Anchors for claddings

All forms of building protection covering the base material, thus, the outer supporting wall against environmental impacts belong to the term claddings. The term “anchor” points to the fixing of greater loads so that heavy-load façades again are the topic. Modersohn is the specialized company for the planning and delivery of façade anchorages for double-skinned brickwork or precast concrete components.

Anchor sleeves

Anchor sleeves are thick-walled threaded sleeves or threaded sockets for higher load capacities that often have transverse mandrels or pull-through reinforcement (through round holes in the anchor sleeve) for a better force application into the concrete. The word “anchor” has its origin in high-performance fixing technology where heavy precast concrete parts are lifted, transported or fixed permanently supporting, as already described for anchoring technology. Modersohn produces special solutions for example as anchor sleeves for connection fixings on in-situ concrete.

Anchor cross joints

Anchor cross joints predominantly serve in monument restoration at the endpoint on tensile anchoring for force distribution in the brickwork wall. They are the alternative for simple quadratic or rectangular fastening plates and shall especially save material in addition to a better optical appearance (since often well visible). In particular, if they are fabricated from stainless steel they can be cut as flat and bended in a way that they can be welded together as a cross. Modersohn produces these anchor cross joints, also designated as St. Andrews crosses, with a diameter of 0.2 m up to approx. 1 m.

Anchoring of concrete façades

The designation anchoring of concrete façades concerns the fixing of suspended precast concrete components that become more and more interesting for a visually appealing and sustainable façade design based on strongly improved concrete grades and production methods, including dying and shaping up to a polished surface. This also includes fixing systems for heavy loads. They have to be slim designed advantageous material costs and a low thermal transfer, and they have to be optimal upon adjustability and mounting. In addition to anchoring systems (fixed-end anchors), Modersohn also offers the MOSO system of the general technically approved panel anchors that is quickly and flexibly available with a high degree of standards. If requested, our own Engineering Office for Structural Analysis will draw up verifiable static proofs.

Anchor channels

At Modersohn designated as MOSO MBA-channel systems with European or German technical approval. Accordingly, Modersohn has a CE and Ü mark for these products.

MOSO anchor channels are embedded flush in concrete with head bolts and foam-filled C-rail so that only the rail top with recess is still visible. After concrete hardening, the foam is removed and mounting of component put before can be started by means of hammer and hook head bolts. MOSO anchor channels facilitate a continuous positioning of the components in one direction corresponding to the channel length.

Anchor plates

Modersohn produces various anchor or welding plates using head bolts, high yield steel anchors (rebar anchors), cleats, threaded sleeves or anchor sleeves in stainless steel or normal steel (galvanized/primed. The head bolts, normally with technical approval, are welded with the anchor plate using the drawn arc method. Head bolts with a diameter of up to 22 mm can be set.

Anchor plates in form of angles- U-profiles or Z-profiles are also possible.

Anchor rods

„Anchor rods“is a term coming from plug technology for threaded parts of fixings of composite mortar systems. These are normally threaded ends with ends especially form for composite mortar mounting, e.g. with external hex and squarely cut end in order to destroy the adhesive mortar cartridge in the borehole in a rotating movements with the anchor rod using the percussion drill and to uniformly mix the adhesive components (resin and hardener).

Modersohn delivers various composite mortar systems with anchor rods made of stainless steel. If necessary, special solutions are realized, since extensive storage and processing possibilities of anchor rods (up to 3000 mm) and round steels in 1.4404, 1.4571 and stainless Lean Duplex steels are available in addition plug storages.

Anchor systems for pre-cast concrete components

For fixing technology in and on concrete, Modersohn processes several hundred tons of stainless steels per annum, MOSO fixing systems including verifiable statics are planned in our own Engineering Office for Structural Analysis. We define "anchor systems" as designed all by the engineer and heavy-load fixings varying on a basic system for pre-cast concrete components, especially in the area of the façade.

Anchor systems for brickwork

For fixing technology of brickwork, Modersohn processes several hundred tons of stainless steels per annum. MOSO fixing systems for the projects including verifiable statics are planned in our own Engineering Office for Structural Analysis. We define “anchor systems“as heavy-load fixings all designed by the engineer according to a basic systems bearing the brickwork walls in variants or standardized, bearing up against tipping or reinforcing. The main focus of Modersohn is façade anchoring.

Attika-brick anchors

„Attika brick anchors” serve to be able to further brick the facing wall over the roof edge area to the top. Normally, there is no suitable fixing base facilitating a direct fixing with air layer wire anchors on the rear brickwork or on the concrete. This especially concerns flat roofs for which the structure is most frequently practiced and the ceiling plate is slidably mounted. The front-mounted brickwork façade would break or crack with a fixing in this concrete caused through thermal motions. Therefore, fixing is done in the support concrete (ring beam) below, and must secure the overhanging brickwork wall using a stiff channel construction and wall connection anchor.

Modersohn most frequently delivers these „Attika brick anchors“in order to plug to the concrete. Wall connection anchors are hooked continuously into the mounting channel using the hammer head corresponding to the position of the horizontal joints in the facing brickwork.

Related terms: Attika anchors, wall connection anchors, Attika facing, Attika-fixing anchors

Anchoring technology

Is comparable with the term „fixing technology“, where the term „anchoring“ has its origin in heavy load fixing technology. Therefore, this term can be also reduced to the heavy bearing and holding anchors with load levels above 2.5 kN. 20 to 30 years ago, the term was often used; nowadays it is less in circulation. In addition, there is the danger of mix-ups with anchor technology in shipbuilding. Nevertheless, Modersohn produces also components made of stainless high-grade steel for shipbuilding.

Attika anchors

The Attika anchor is a bearing and fixing anchor for cladding elements if they considerably overtop the floor ceiling of the building. “Attika” comes from Greek and refers to an architectural element that shows well visible inscriptions, status symbols, figures and ornaments on representative structures especially in the ancient and in later epochs. Nowadays, Attika facing is an important protection of the roof finish on flat roofs where special requirements are made on the fixing, for example in the case of “Attika brick anchors. They serve to be able to further brick the facing wall over the roof edge area to the top. Normally, there is no suitable fixing base facilitating a direct fixing with air layer wire anchors on the rear brickwork or on the concrete. This especially concerns flat roofs for which the structure is most frequently practiced and the ceiling plate is slidably mounted. The front-mounted brickwork façade would break or crack with a fixing in this concrete caused through thermal motions.

Therefore, fixing is done in the support concrete (ring beam) below, and must secure the overhanging brickwork wall using a stiff channel construction and wall connection anchor. Modersohn most frequently delivers these „Attika brick anchors“in order to plug to the concrete. Wall connection anchors are hooked continuously into the mounting channel using the hammer head corresponding to the position of the horizontal joints in the facing brickwork.

Brickwork support

The term brickwork support refers to the fixing of most various bricks with bearing and holding anchors in the clam-shell wall structure of the façade. Modersohn also strut glass bricks and other brickwork types in addition to clinker, bricks, lime-sand bricks, concrete stones and natural stones. For about 40 years, MOSO brickwork support systems have been successfully applied. New stainless materials such as the Lean Duplex steels (D4 - 1.4062, 1.4162, 1.4362, 1.4482) ensure that the product became even more favorable despite considerably increased efficiency.

Brickwork support

The term brickwork support refers to the fixing of high-fired bricks with bearing and holding anchors in the clam-shell wall construction of the façade. Proper clinker stones are simply the optimum cladding. This was already known from 1870 to 1914 where clinker stones (bricks burnt with higher temperatures) that were produced and processed true so size and especially in great demand in façade construction. This means that in addition to the stone true in size, also the joints were applied narrowly and exactly to also please optically as faced brickwork, in addition to frost resistance. Such a high-quality facing must be fixed accordingly with high-strength and slenderly designed fixing systems made of stainless steel. For about 40 years, Modersohn provides the brickwork support made of stainless steel.

Since 2006, Modersohn also uses high-strength and stainless steel Lean Duplex steels, facilitating a very slender construction of brickwork support and thus, considerably reducing procurement costs thermal conductivity values.

Brick tie anchors

Brick tie anchors are fixing anchors consisting of perforated and/or profiled flat steel. They serve for the lateral stabilization of the brickwork wall and are set with one end into the mortar of the brickwork joint upon bricking up. Normally they have a hammer head on the other side that is infinitely variable and mounted into an anchor or mounting rail. With this, the “brick tie anchor“ can be adjusted suitably to the horizontal joint of the brickwork wall. Related products are wall connectors that are set in, however, on both sides with the ends upon bricking and thus, have a continuously equal perforation and or/profiling. They are only suitable for butt joint connections of brickwork walls relatively identical in construction since the joint inserts must be on the same height. Therefore, Modersohn mostly sells „brick tie anchors“ produced as standard system or special form for connecting into a vertically arranged profile rail, the so-called “brick tie channel”.

Product information: brick tie systems at Modersohn

Related terms: brick tie systems, brick tie anchoring, brick tie fixing, wall anchors, wall fixing anchors, wall connection anchors, connection anchors, wall connectors, brick tie channels

Brickwork connection

The force-fit connection of brickwork walls among each other is important, for example if brickwork inside walls hot load-bearing exterior brickwork and even very different brickwork types hit each other. As a rule, even wall connectors with a technical approval of DIBt (German Institute for Building Technology) are applied for such a butt area. They are inexpensive, but must be already planned or installed for the wall that has been built at first and look out halfway through in order to brick the connection wall. If wall connectors are lacking, the brick height of the connection brick is not identical, or special force has to be intercepted, so the problem can be solved using plugged rail profiles and continuously adjustable brickwork connection anchors.

Modersohn provides an important supplement with the MOSO perforated type (brickwork reinforcement) for brickwork butt areas against vibration and settlement crack danger. With the term “brickwork connection“ also the connection between other building connections such as concrete or steel truss or rather steel girder can be meant. For this purpose, Modersohn offers special solutions.

Related terms: butt technology, wall connections, terminal connectors, brickwork reinforcement, brickwork sheathing, brickwork connection

Beveled profiles

At present “beveling” using a sword or prism on a mechanical or hydraulic press is the most frequently applied deformation method for plates or rather panels made of metal. The hydraulic beveling presses applied at Modersohn can deform plates or panels made of stainless steel, aluminum, brass, copper and other metals quickly and precisely according to customer requirements. Especially precise bending areas with an angular accurateness of up to +/- 0,2° are possible through an automatic crowning bow and laser tracing during the beveling process. Modersohn fabricates various precision profiles also for assembling measuring devices in plant construction and engineering.

Brick tie channels

Normally, „brick tie channels“ are C-shaped or trapezoidal support bars for mounting the wall connections anchors. Together with the wall connection anchors, the wall connection rails serve for the stabilization and the connection of brickwork walls to the same or different building materials. The most flexible solution is a C-rail (mounting rail) with punched oboblong holes in the frontward side that is mounted to the bearing displacement base using suitable plugs. The developing joint gap through the wall connecting rails (for ex. profile 28/15 mm with a t panel thickness of the rail of 15 mm) can be normally filled with mortar. Our own engineering office for structural analysis can advise you technically and provide you with suitable accessories from our comprehensive stock.

Beveled sheet metals made of aluminum

At present, “beveling” using a sword or prism on a mechanical or hydraulic press is the most frequently applied deformation method for plates or rather panels made of metal. The hydraulic beveling presses applied at Modersohn can deform aluminum cuts quickly and precisely, e.g. to an angle, U-profile, Z-profile or cap profile. When cutting on the laser or on the water jet cutting system, also holes and recesses can be included.

Related terms: beveled profiles, k, press profiles, bending profiles, special profiles

Brickwork reinforcement

Brickwork reinforcement is the stabilizing of the brickwork wall (washer) in the hardened mortar compound via allowance of profiled power taking material in the brickwork joints. They can include profiles (strips, high yield steels) or fabric made of steel, stainless steel and also fiber-reinforced plastics. With the MOSO perforated tape, Modersohn has developed a brickwork reinforcement that is technically approved for supporting lintels being produced from high-strength steel (galvanized) or stainless steel (Lean Duplex steel D3). The MOSO perforated tape can be also applied in thin-bed joints and adhesive joints based on the low tape thickness. Gripping and thus, the reinforcing effect, always ensue via round holes with the hardened mortar or adhesion plug contained in them. This hole compound is verifiably more sustainable compared to ribbed bars which is proven by tensions tests.

Accordingly, the MOSO perforated tape is also applied as crack safety against shrinkage cracks and for point load and lateral load stabilization. Another major advantage of the MOSO perforated tape is that it is delivered on a roll in a cardboard box with a length of 25 m, 50 m or 100 m and that the required length can be cut off precisely fitting with tin snips without cuts.

Collecting trays

Collecting trays serve for a secure recording of liquid materials and bulk materials, for example not to let hazardous substances seep or to collect useful materials. For many years Modersohn has produced „stainless trays“for industrial purposes. In addition to drip trays in food industry and for example for castor tanks in the area of nuclear power stations, collecting trays have been also produced for the painting shops of a large aircraft manufacturer or simple drip trays for production machines. The system tray production for hazardous substances storage has a large share at Modersohn, with proof of the German Water Resource Act (WHG) and leak tests (dye penetration method or vacuum test method), which completely checks the trays before delivery. This is already an interior design for very large trays. Experienced welders of Modersohn are welding the cladding parts prefabricated in the plant on site.

Compound anchors

Compound anchor is a collective term for many variants of adhesive or mortar anchors standing out due to a stress-free anchoring in concrete or brickwork within the borehole. Expansion anchors or rather expansion plugs, however, press the borehole apart. Compound anchor technology is especially advantageous for plug or needle fixings (deeper boreholes) in flexible building materials and for relatively small edge distances to the lateral edge of the fixing base. The fixing type most frequently applied for heavy-load anchors are compound plugs or rather adhesive plugs the adhesive mortar of which is pressed into the borehole using cartridges or fuses. Such compound anchors mostly consist of 2 components, one is adhesive resin and the other one the hardener. When pressing into the borehole, both components mix and react with each other so that the threaded rod or anchor rod plugged in is firmly bonded with the borehole after a relatively short setting time.

It is important for a frictional connection that, in addition to the good mixing of the components, also a flushing of the borehole is performed so that not loose building material particles prevent the crimping effect of the adhesive or rather mortar with edge of the borehole. As a partner of the companies Fischer Dübel (Tumlingen, Denzlingen) and Hilti (Kaufering), Modersohn sells a wide range of compound anchors. In addition, Modersohn itself produces various anchor rods in special forms and sizes, also with the approval in individual cases.

Clamping connections

Modersohn delivers a multitude of tension structure on the ends of which threaded parts are applied in order to extend the tension rod using a clamping sleeve or to apply forces. Alternatively, forces are applied to the clamping connection via tightening nuts in the area of end structures (for example force distribution plugs for brickwork). Modersohn very often delivers threaded rods of M6 – M42 in lengths of 3000 mm taking over the task of a clamping connection using suitable coupling sleeves and end plates. The new threaded rods according to DIN 975 mad of stainless Lean Duplex steel 1.4362 are very economical as a technically better and thus a cheaper alternative to A4/A5 steel.

Related terms: tension anchoring, tension rods, prestress, double ends, tendons

see also: tension anchors, prestressed anchors, clamping sleeves, threaded rods, threaded sleeves

Clamping sleeves

Are internal thread sleeves with left-hand and right-hand thread as well as a device for turning the clamping sleeve during the assembly. The internal thread can be throughout long or undercut. Where undercutting from solid material or thick-walled tube (hollow steel can be very costly. Clamping sleeves pressed from the tube or short threaded sleeves (or nuts) with 2 laterally welded round or flat members are cheaper but normally cannot absorb so large forces. The devices for tightening can be a round hole into which a round member is inserted as a clamping lever. This means, however, a reduction of the cross-section which can be statically disadvantageous.

Another possibility is the tightening with a wrench, in which the clamping sleeve is designed as a hexagon or centrally milling two opposite flat sides in case of a round sleeve. On them, the spanner or tongs can grab. Modersohn produces clamping sleeves in a metric coarse thread of M6 – M52.

Related terms: span sleeves, span members

Clamping anchors

Clamping anchors are special cantilever anchors in the form of a cap or omega profile. They are applied for the bearing fixings of precast concrete panels in the façade area, and are mounted on the ceiling plate of the floor. This is realized by means of a plug or anchor channel. The profile form provides enough stiffness in order to bridge the air and insulating layer in the Attika area or to bear the railing panel in the parapet area of a balcony. Modersohn produces MOSO clamping anchors made of high-strength stainless Lean Duplex steel (1.4062, 1.4162, 1.4362, 1.4482) with technical approval Z-30.3-19. These materials are considerably more corrosion resistant, especially during stress corrosion, compared to the classic austenitic grades (1.4401, 1.4404, 1.4571).

In addition, material cross-sections can be minimized based on the double as high basic strength of the material reducing the product price together with the more favorable purchase price of the material.

Copper cuts

Modersohn delivers water jet cuts fabricated from copper plates for different applications in plant engineering, mechanical engineering or civil engineering. The cuts may have a round or angular outer contour and also holes and recesses. The material thickness can be also chosen variably. Everything is possible from 1 to 100 mm. The copper cut can be deformed as requested (edging, rounding, bending). Applications regarding joining technology are possible, so that complete constructions can be produced. Prof. Dr.-Ing. Wolf Berend Busch and Rüdiger Gottwald of our supervision for joining technology can give some additional information.

Elastomeric bearings

Modersohn delivers „elastomeric bearings“in form of unreinforced and reinforced rubber bearings, with or without technical approval. Typical material thicknesses of these rubber bearings for stock balancing and damping regarding concrete elements are 3.5, 10 and 20 mm. The rolled-up square meter goods are stored in formats per 1200 x 3600 mm. As required, Modersohn can produce cuts from them and punch holes into them.

Edge protection profiles

Stainless steel profiles or normal steel profiles (galvanized, primed) are produced for the protection of concrete edges or plaster edge by Modersohn. Edge protection profiles made of aluminum, brass or copper are also possible. Using concrete anchors for plugging or gluing depending on the material. Normally, edge protection profiles are in angle form with different leg lengths and profile lengths as required. Very heavy designs as impact protection are also possible, such as tank training areas and washing areas or on starting ramps at the forwarding agency. Modersohn can also bring ornaments and forms in the optics of edge protection layers using laser or water jet cutting plants.

Façade plug

The term “façade plugs” was created by the company Upat from Emmendigen (taken by the company Fischer) comparable with “long shaft plugs” or “frame plugs” depending on the producer. Normally, it concerns expansion plugs with a long countersunk screw or hexagon head screw which is applied with a longer bonding depth (usually up to 90 mm) and a special long fixing shaft in the façade area. The relatively large bonding depth shall improve the holding values also in the wall brickwork (also perforated bricks). In former times, even façade plugs with a total length of 320 mm were produced that had a maximum fixing thickness of 230 mm. As the name suggest, the plugs were exclusively applied in the façade and were often used in connection with the so-called air layer eye anchors for the renovation of the clam-shell brickwork façade.

As a partner of the companies Fischer and Hilti, Modersohn delivers most different frame plugs including possible necessary surface floor installation parts made of stainless steel, aluminum or normal steel.

Frame anchors

The term „frame anchors“, also designated as “frame anchor” or “long-shaft fixing” is a plastic expansion anchor with an especially long fixing shaft. The screw has a special countersunk that can be also covered with a cap. Various frame constructions requiring a larger fixing thickness can be also fixed cleanly with regard to optics. As a partner of Fischer and Hilti, Modersohn delivers most various frame anchors including possibly necessary mounting parts made of stainless steel, aluminum or normal steel.

Façade substructures

Façade substructures are a collective term for all holding and bearing anchor systems behind the façade cladding. Normally, substructure means a connected system-based profile structure and less an arrangement of single anchors. The expectation is that such a substructure offers a high degree of adaptation or adjustability for the specific fixing situation. Modersohn provides such profile systems for heavy-load façades (brickwork facades, precast concrete part façades), especially for façade areas with difficult fixing bases. These are for example wind post systems or Attika fixings. These systems guarantee a high stability and adjustability. In addition, Modersohn produces substructures for solar module cladded substructures according to customer specifications.

Façade anchors

Façade anchor is a collective term for all façade fixings or façade fixing systems. These bearing and holding anchors systems are often made of stainless steel. In addition to corrosion resistance, especially in case of permanent moisture in mineral building materials which then have corrosive effect with galvanized surfaces, the relative low thermal conductivity value λ = 15 (Lambda-value, W/[m*K] is interesting as façade building material. Compared to aluminum, λ = 150 is set as alloy and λ = 45 is set for normal steel (galvanized). Especially if it concerns heavy-load fixings in the façade, it is important to reduce the fixing structure once again in the cross-section using high-strength Duplex stainless steels in order to minimize heat transfers. In cooperation with the Fraunhofer Institute for construction physics in Stuttgart, Modersohn investigated numerous example façades and discovered that a cross-section reduced and well designed façade anchor made of high-strength stainless Lean Duplex steel 1.4062, 1.4162, 1.4362 or 1.4482 results in the greatest insulating effects. A presently possible thermal separation by means of plastic that is possibly porous has by far not that success even for partition thicknesses above 10 mm.

With a thermal separation called “MOSOTHERM”, an epoxy resin filled with hollow microspheres, Modersohn did not reach a notable reduction of the thermal conductivity in relation to the fixing problem and the additional costs. Despite the fact that many of the offered (more or less) pressure transferring foamed plastics are often very questionable with regard to durability and creep behavior at higher temperatures and will certainly not obtain the necessary technical approval.

Faced brickwork anchoring

The term "faced brickwork“ has its origin in the word „facing” which is a stone for the “facing brick”. From 1870 to 1914 these were clinker stones (bricks burnt with high temperatures) that were produced and processed due to size. This means that in addition to the stone true to size also the joints were structured narrowly and exactly, in order to please optically as facing brickwork in addition to frost resistance. Nowadays, to this function as an optic cladding and the general weather protections of the building, the function as a part for a clam-shell thermally insulated façade was added. With the MOSO brickwork fixing, Modersohn delivers a perfect system made of high-strength stainless Lean Duplex steel.

These high-grade steels extensively tested by Modersohn since 2013 and technically approved stand out for façade fixings due to a slender structure, less use of materials and thus, lower costs, and a very low heat transfer. In addition, Lean Duplex steels (1.4062 and 1.4362) provide a considerably higher corrosion resistance in this field of application compared to A4 or A5 steel, also close to the sea.

Façade suspension

The term facade suspension is colloquially used as a collective term for a variety of most different façade fixing systems. Compared to supporting, elevating, bracing or intercepting on brackets the term can be interpreted professionally in a way that it concerns a fixing systems that directs forces of the façade to the side or further upwards into the displacement base. Such fixing systems often work with tension rods in form of threaded rods or flat steels that adjustably and flexibly extrapolate the forces of the façade to the side or further upwards via plugs or anchor channels into the supporting rear wall. As an example, Modersohn produces the so-called MOSO panel anchor for precast concrete part façades with a very slender and well adjustable structure made of stainless steel. Such a panel anchor consists of the so-called “installation part” for concreting into the precast concrete part to be attached, the in-situ concrete which can be a plug or an anchor channel and the “mounting part” connecting both consisting of a threaded rod with head part and nuts.

In the lower and lateral area of the precast concrete part pressure screws and possibly handrail panels are necessary for an exact positioning and fixation of the precast concrete panel opposite to the wall surface of the load-bearing rear wall. Such a “façade suspension“with tension rod can absorb loads of precast concrete parts with above 50 kN. Civil engineers and technicians of Modersohn are planning optimum „façade suspensions” for heavy-load façades for you.

Facing brackets

"Facing brackets" are support anchors that are especially designed for façade walls prebuilt with mortar. For almost 40 years, Modersohn has delivered the brickwork anchoring systems contained in this term. The façade facing with clinker stones in from of a double-sheet wall structure with insulation and air layer has proved to be especially sustainable in the last years for large buildings. This requires also perfect and very durable façade load-bearing systems as they are produced by Modersohn. MOSO brickwork supports are produced very slender, with high-strength bearing and holding structures made of the stainless Lean Duplex steels 1.4062, 1.4162, 1.4362 and 1.4482. See also bracket anchors at Modersohn under the term "ecoINOX.

Façade panel anchors

The term façade panel anchor is understood to mean all bearing and holding anchor systems for precast concrete part claddings in the outdoor area on buildings. In addition to the known „clamping anchors“ for Attika and parapet panels, Modersohn also delivers “panel anchors”, “support consoles”, “drilling-through anchors” handrail panels”, “grouting” and “pressure support transfers”. Through the application of technically approved high-strength stainless Lean Duplex steels (D4), Modersohn can design “façade panel anchors” more slender and cost saving or they can be more heavily loaded. Also the E-modulus may be set higher by about 18 % compared to A4 steels. Our own engineering office for construction analysis can submit specific proposals with regard to the anchorage for the suspension of façade panels and provide verifiable static proofs.

Edge profiles made of stainless steel

A metal sheet profile that was cold-formed through a sword or prism. The production is effected on a so-called press brake, it is also designated as folded press. Edge profiles made of stainless steel are also called trimming press or stainless steel profile or they are name as a special profile form such as stainless steel angle, U profile, Z profile etc.

Elastomeric bearings

Modersohn delivers „elastomeric bearings“in form of unreinforced and reinforced rubber bearings, with or without technical approval. Typical material thicknesses of these rubber bearings for stock balancing and damping regarding concrete elements are 3.5, 10 and 20 mm. The rolled-up square meter goods are stored in formats per 1200 x 3600 mm. As required, Modersohn can produce cuts from them and punch holes into them.

Façade anchors

Façade anchor is a collective term for all façade fixings or façade fixing systems. These bearing and holding anchors systems are often made of stainless steel. In addition to corrosion resistance, especially in case of permanent moisture in mineral building materials which then have corrosive effect with galvanized surfaces, the relative low thermal conductivity value λ = 15 (Lambda-value, W/[m*K] is interesting as façade building material. Compared to aluminum, λ = 150 is set as alloy and λ = 45 is set for normal steel (galvanized). Especially if it concerns heavy-load fixings in the façade, it is important to reduce the fixing structure once again in the cross-section using high-strength Duplex stainless steels in order to minimize heat transfers. In cooperation with the Fraunhofer Institute for construction physics in Stuttgart, Modersohn investigated numerous example façades and discovered that a cross-section reduced and well designed façade anchor made of high-strength stainless Lean Duplex steel 1.4062, 1.4162, 1.4362 or 1.4482 results in the greatest insulating effects. A presently possible thermal separation by means of plastic that is possibly porous has by far not that success even for partition thicknesses above 10 mm.

With a thermal separation called “MOSOTHERM”, an epoxy resin filled with hollow microspheres, Modersohn did not reach a notable reduction of the thermal conductivity in relation to the fixing problem and the additional costs. Despite the fact that many of the offered (more or less) pressure transferring foamed plastics are often very questionable with regard to durability and creep behavior at higher temperatures and will certainly not obtain the necessary technical approval.

Grout-in anchors

"Grout-in anchors“is a further term for „compound anchors” which is primarily used for bearing and holding anchors in the fixing area of natural stone. The fixing systems produced from wire, round steel, threaded rods or tube are set into round holes with mortar. For heavy loads also larger components are set into bearing brickwork walls with special mortar, for example for façade renovation. Therefore, grout-in anchors are less assigned to universal plug systems but more to special systems and special manufactures for certain fields of application.

Heavy-load fixings

Heavy-load fixings is a collective term from civil engineering that from experience describes bearing and holding anchors with load levels over 2.5 kN. Among them are light fixings that also get by with simple expansion anchors, for example made of plastics.

Heavy-load plugs

General term for bonded anchor and expansion anchors systems for load levels above 2.5 kN and more. In the area of façade fixing, Modersohn sells especially glued plugs with toner or cartridge, and anchor rods made of stainless steel. In the meantime, many of the anchors rods consist of the high-strength stainless Lean Duplex steel instead of the austenitic materials 1.4401, 1.4404 or 1.4571. Thus, bonded anchors reach tensile loads of about 75 kN in corresponding uncracked concrete.

Head bolt anchoring

Head bolt anchoring are round steels with single-sided molded round head or hexagon head. In civil engineering they are most frequently welded on anchors plates and anchor rails. The head bolt anchors are also cast into the concrete and serve as a bearing element for the mentioned terminal fixings for components such as supports, parapet, façades etc. In Germany, a technical approval is required for bearing structures regarding head bolt anchors. In addition, a great many edge protection structures for concrete edges with head bolts are applied. Modersohn processes head bolts with a diameter up to 22 mm using the arc ignition method. Head bolt anchoring in stainless steel as well as in normal steel (galvanized or primed) are produced. Mixed compounds are also possible.

Laser cutting

At present, laser cutting, as a thermal separation method for plates, is the most important shape cutting method for plates made of steel, stainless steel and also non-ferrous metals. As an alternative, water jet abrasive cutting is to be mentioned which has, however, considerably slower cutting speeds for thinner plate thicknesses compared to the laser. When laser cutting is performed on stainless steel that is cut using nitrogen as a process gas, the focal point of the laser beam is on the bottom of the plate. This results in a melting of the kerfs from bottom to top. Therefore, this is termed “laser fusion cutting” where the nitrogen gas serves for exhausting the molten mass of the joints and as a protection gas for preventing that the cut edges oxidize. When cutting normal steel that is cut using oxygen as process gas, the focal point of the laser beam is on the top of the plate. The energy releasing with the oxygen leads to a combustion process that considerably accelerates the cutting speed once more.

Therefore, this is termed „laser beam flame cuts”, similar to autogenously flame cutting. The inflated oxygen has also the task to blow out the iron oxide (slag) from the joint (blowing gas). In its production, Modersohn has all important cutting methods. Laser plants of 4 and 5 kW are available that can also process tubes in addition to plates. Plates made of stainless steel can be processed with a thickness of 0.5 to 25 mm.

Laser cuttings

At Modersohn, laser cutting is a fabrication method for a precise and inexpensive form cutting of plates or metal plates made of stainless steel, normal steel (ST) or aluminum. Plate thicknesses up to 25 mm (for stainless steel) and a format of 2000 x 4000 mm can be cut with our 4 and 6 kW plants. For high-alloyed materials (for example stainless steel) laser cutting is operated as melting with a laser focus on the bottom plate side using nitrogen and for non-alloy or low-alloy materials (normal steel ST) with a laser focus on the top plate side using oxygen as cutting gas.

Lean Duplex steel

Type of structure within the material area of stainless steel where about half of the basic types of the structure “ferrite” and “austenite” result in the so-called “Duplex steel” as mixed structure. The designation “Lean” is the Standard or Common Duplex steel 1.4462 known for many years. The new types designated as stainless Lean Duplex steels are 1.4062, 1.4162, 1.4362, 1.4482 and 1.4662, i.e. all materials lower-alloyed than 1.4462. Compared to the pure austenitic types (for example 1.4301, 1.4404/1.4571), considerably higher strength, the elasticity module that can be set higher and in normal atmospheric areas (up to 50°C) a higher corrosion resistance, especially in danger of stress crack corrosion.

Manufacturer's qualification class E

In the field of jointing technology or welding technology it is a valid proof of suitability that has to be regularly renewed in the company through a control of external examiners (mostly through staff members of a training and testing institute of welding). There are the class B, C, D and E. Class E existing at Mo9dersohn is the most extensive qualification for which a welding engineer is necessary as a welding supervisor. Formerly designated as „large welding certificate“, „proof of suitability for welding”, “large proof of suitability”.

MAG welding

Metal active gas welding (MAG welding) is the most important welding method at Modersohn and is applied for most of the fixing parts in civil engineering. The metal wire (filler metal) is conducted from the cable roll to the welding gun. The wire emerging on the welding gun in front is supplied with a high stress which produces an arc upon contact of the wire tip with the work piece surface. The wire melting through the conduction resistance can be applied relatively clean and uniform as a weld. So that such a welding wire melt does not react with oxygen at one und thus oxidizes, a so-called protection gas such as argon or an argon-CO2 mixture is also blown on the welding process on the top of the pistol. Modersohn uses welding wires with a diameter of 0.8 – 1.0 – 1.2 mm.

Mounting parts made of stainless steel

The term „mounting part „regarding fixing technology in civil engineering must be considered in combination with the term “installation part”. A mounting part for example is casted into concrete whereas the installation part is the fixing that serves as a link to the locally bearing structure during installation on site to the already incorporated part (mounting part). This differentiation into „mounting part „and „installation part“ can be often found for fixing systems of precast concrete parts. Modersohn produces fixing systems with „mounting parts”, for example for MOSO-brickwork support anchors.

Needle anchors

Everywhere where very thick brick walls (for example in the area of dados of a castle wall), natural stone or deposits are to be secured against drifting apart or slipping off, very deep (partly several meters) are drilled into the round holes using special drills. There, so-called “needle anchors” are sticked in. Needle anchors combine the property of tensile strength and reinforcement. They consist of a profiled bar profile (needle) that has a holding or load-bearing plate on only one side. Normally, the profile is a profiled round steel (for example rebars, threaded rod), being grouted with mortar or adhesive in the borehole.

The head plate or an anchor cross is mostly screwed on so that a prestress can be applied through tightening of a nut after the setting process. Modersohn produces the needle anchors in various lengths and cross-sections.

Non-ferrous metals

„Non-ferrous metals“ (NF-metals) are understood to mean all metal alloys, in which iron (Fe) does not occur as main alloy element. On the metal market these are normally copper, aluminum, brass or bronze alloys if it concerns plates, profiles or tubes. Modersohn processes non-ferrous metals on cutting plants (among others water jet cutting, laser cutting etc.), sawing, milling and press braking.

Recessing bodies

Recessing bodies

Modersohn most frequently delivers recessing bodies for in-situ concrete or concrete components as plastic sleeves in round or oval form with an open end for taking up guiding spikes and pinned fitting spikes that are produced from round steels. In addition there are foams or rather PE or PS foam elements that are grouted into the concrete and scratched out later. The recessing bodies, however, can be produced from stainless steel or normal steel (galvanized, primed). The term also includes the so-called „lost shutterings“. Another area of recessing bodies are pipe and cable ducts for which openings or channels are recessed by means of pipe segments or frame constructions.

Panel anchors

Panel anchors are heavy-load support anchors for facades that are applied in pairs for suspended precast concrete panels. Such a panel anchor systems is composed of the so-called “installation part” for concreting into the precast concrete part to be suspended, the so-called in-situ concrete fixing, this can be a plug or an anchor channel and the “mounting part” connecting both that normally consists of a head part and nuts. In the lower and lateral area of the of the suspended precast concrete parts, pressure screws and possibly handrail panels are needed for an exact distance positioning to the supporting rear wall. Such a “panel anchor” is designed to be slender being advantageous for material costs and a low heat transfer. In addition, a versatile adjustability and simple mounting are important, since for the heavy concrete plates only a very little range of motion for the attachment is available.

Therefore, in addition to cantilever anchors (clamping anchors) MOSO panel anchors are especially economic. They have a technical approval, and are also quickly available from stock based on the system standard. Our own engineering office for construction analysis draws up verifiable static proofs on demand.

Parapet anchors

Parapet anchors are heavy-load fixing systems for precast concrete parts on balconies (as balcony railing), overhangs and claddings in the Attika area of the façade. Normally, they consist of the supporting anchor that is designed as an overhanging profile (anchoring element for example as cap profile [clamping anchor]) for a direct force introduction into the displacement base. Holding anchors in form of tooth holder anchors and pressure supports ensure that façade plate systems fixed in this way do not lead to vibrations at wind pressure-suction or tremors.

Modersohn also offers such anchor systems cost-effectively made of high-strength Duplex steel (1.4062, 1.41,62, 1.4362, 1.4482) with technical approval Z-30.3-19, with which material cross-sections can be reduce and the fatigue strength can be considerably improved in addition to the equal corrosion resistance to A4/A5 at least.

Parapet anchors

Parapet anchors are concrete precast fixings for concrete façade plates, for example in the area of balconies or windows serving for fall protection. Such concrete precast plates are of course always a structure protection and have to be applied with statically designed bearing and holding anchors, especially at in-situ concrete. Especially solid and often applied fixings for this area are anchoring elements in form of so-called clamping anchors transferring the forces from the concrete precast plate directly into the in-situ concrete by means of a very solid cap profile, where they are plugged on ceiling panels or screwed on anchor channels.

Permanent scaffolding anchors

The stable fixing of scaffoldings is only possible for large or high structures using special holding anchors. These fixings permanently remaining in the façade and subjected horizontally and to tension are basically made of stainless steel in double-shell façade construction. „Permanent scaffolding anchors „are designed with an internal threaded sleeve for which later only the outlet in the joint area of the brickwork façade protrudes. Only if a scaffold for façade works is errected, a ring bolt is screwed in establishing a connection to the scaffold.

Precast lintel fixtures

Brickwork lintels more often are no longer bricked but suspended to console anchors as finished prefabricated part with appropriate brickwork optics through straps or special angular stones that can be concreted. The total system is called „precast lintel fixture“, and consist of two anchor channel, normally with an anchorage U-shaped bracket instead with head bolts. Hammer or hook head screws and two fixing consoles bear the concreted precast lintel. A height adjustment is effected via the adjusting system using the V-pulley on the supporting bracket head. The oblong holes of the holding plate of the bracket and the anchor rail in the prefabricated part allow for an adjustment to the sides and into the depth. Since the precast lintel is additionally reinforced, it can be immediately applied for the lining of the additional façade wall. Thus, a further angular interception can be dropped. Modersohn delivers „precast lintel fixtures“ of this type as „FB-U” with technical approval Z-21.4-1907. Furthermore, there are further “precast lintel fixture systems” that make use of the lateral brickwork directly on the window or door opening.

Reinforcement stirrups and/or reinforcement plates are concreted on both ends of the lintel and the whole concrete component lintel is put on the laterally lined supporting walls. Also these systems are produced by Modersohn depending on the demand situation.

Plug anchors

Plug anchors are air layer holding anchors in the double brickwork of a façade. In the displacement base, normally in the load-bearing brickwork, they are punched uniformly distributed into drilled round holes using a special plastic expansion plug (basic rule 5 units square meter). They shall prevent the relatively slim brickwork façade (11.5 cm and less) from tipping and buckling. The length of the plug anchors is chosen in a way that they bridge the insulation and air layer and that they at the end protrude at least 50 mm into the horizontal joints of the facing shell with a bending of 90° (turning length ≥ 25 mm). Nowadays, more technically approved plug anchors with shaft end are sold Instead of the bent off ends, saving the process of bending off. In addition the plastic plug sleeves are firmly pre-assembled on the wire so that mounting with the drive-in tube that is put over the wire during the setting process, is very simply. The technical approvals reach up to a shell distance of 200 mm. Modersohn also delivers air layer anchor systems for larger shell distances. According to DIN EN 1996-2-NA, thus, part 2 of the National Annex of Eurocode 6 “Brickwork shells are to be connected through anchors made of stainless steel according to the general technical approval or through anchors made of stainless steel according to DIN E_N 845-1 the use of which is regulated in a general technical approval. With this the application of stainless steel for bearing and holding anchors in the double brickwork façade is mandatory.

It is only left open from which stainless steel grade the anchor is produced. These are increasingly technically approved Lean Duplex stainless steels (D4) that have considerable advantages with regard to technology and price compared to the A4 grades. These steels are different from A4 steels, because of their ferrite magnetically attracted share of the structure, so that a check with the magnet on the site to verify that no galvanized normal steel had been processed is hardly possible. For this reason, test certificates, inspection certificates and approval documents should be delivered completely in advance. Civil engineers and technicians of Modersohn can help you with the planning of the right air layer anchors. Modersohn can satisfy your needs short-term from a large stock range of different air layer anchor systems.

Pressure transmitting insulation

In order to fix the cladding with a possibly slender fixing cross-section made of metal (or stainless steel) in the façade area, it is useful to supplement or exchange the fastening components with a considerably lower heat conducting material. Pressure loads, oblique tension or shear loads can be also intercepted with plastics for example.

The prerequisite is that the material has a corresponding load-bearing capacity, environmental resistance and service life in addition to sufficient values for thermal separation. As an alternative it is also possible to build the bearing and holding anchors of façades more slender through improved material strengths for example using stainless Lean Duplex steels or through improved structural details and thus, to reduce thermal bridges. Modersohn does this simultaneously. The pressure transmitting insulation “MOSOTHERM” has been developed for this purpose.

Railing fasteners

Modersohn offers different fixing systems for railing fasteners. In the area of plugs, Modersohn delivers systems for the cracked tensile zone and connection anchors with corresponding technical approval. In addition, anchor plates or welding plates with approved head bolts are produced on demand. In addition to stainless steel, the customer also receives designs in normal steel galvanized or primed. Also special designs for the fixing on timber are produced.

Reinforcement steel

Reinforcement steel or or „reinforcement bar” are rebar steels as single rod, mat welded or basket welded, bound and bended. Modersohn especially delivers the design in stainless steel. Lean Duplex steels are more and more applied for high yield steels since the basic strength of the material and the cirpping effect are considerably higher and the material procurement costs are more favorable compared to those of the classic A4 steel. The corrosion resistance for the stainless Lean Duplex steels 1.462 or 1.4062 is above that of 1.4404 or 1.4571.

Reinforcement technology

The term reinforcement technology characterizes a branch of industry with the task to stabilize concrete and brickwork and to transfer or redirect forces. Normally, profile steel is inserted for the production of concrete and brickwork structural components. In this way, typical reinforcement technology can be circumscribed in general. In this area, Modersohn occupies a series of niche applications with stainless steel. In addition of the typical rebar made of A4 or D4 (Lean Duplex steel), Modersohn has delivered the universal brickwork reinforcement MOSO perforated tape for years. It does not only for the simple decrease of cracks in the brickwork, but it is normally applied for intercepting falls of windows and door lintels in facing brickwork, a force deflection occurs into the lateral supporting brickwork using the MOSO perforated tape.

Reinforcements made of stainless steel

Modersohn delivers reinforcement systems for concrete and wall brickwork. Normally, rebars or MOSO clamping band (wall brickwork reinforcement) consist of stainless steel. The reason is that galvanized steels in the alkaline environment of concrete or mortar, connected with permanent moisture, corrode very quickly. It becomes very problematic if sulfide precipitation accrues, for example with clinker façades. With “permanent moisture” it is not the question of several years but of a few months at most. This can be already a wet season where there is no real dying process in the wall or in the air layer as investigations have shown weather-exposed sides of buildings. Zinc dissolves in a very short time forming white rust. At first, however, white rust does not look dangerous so much. But it is less material destroying compared to the immediately eye-catching brown rust. Permanent moisture is no problem for stainless steel even it concerns very inexpensive material qualities such as chrome steel 1.4003 that is often processed as rebar in Switzerland.

Especially chrome steel and Duplex steels are technically very interesting, particularly for concrete reinforcement. Based on the ferrite share of structural elements (attracted magnetically), they have a considerably higher cripping effect of the surface (stronger surface roughness) compared to austenitic steel grades such as 1.4401, 1.4404 or 1.4571.

Refurbishment brackets

An important field of activity in building industry is the subject “building with existing structures” or also “called “retrofit”. For the repair of bearing components or rather structural parts, Modersohn offers numerous special support anchors. The refurbishment brackets are support anchors at the displacement base on which components are applied and partly fixed with mandrels. These brackets serve for securing existing additions or façade elements of concrete and brickwork walls or for safely supporting or bearing old building materials after reconstruction. The background is that the existing older building structure can be severely checked or determined with regard to the load-bearing capacity and general quality of the building material. Our own Engineering Office for Structural Analysis is gladly prepared to advise you for the choice of refurbishment fixing systems.

Many of the refurbishment brackets are variant structures on the basis of statically designed basic systems, and are predominantly applied in monument restoration.

Refurbishment anchors

Modersohn produces refurbishment anchors for the safety and replacement of bearing and holding anchors with an existing structure. Present fixing systems from past decades are often produced from galvanized normal steels and corroded in certain buildings, especially façade areas. They may result in failure. For a total refurbishment it is often sufficient if only a part of the bearing or rather holding constructions are considered as critical during inspection. A reason for such a radical measure is that only a very small part of the cladding or rather façade can be removed for assessment, so that after view (for ex. on the weather face of the façade) the complete façade is rejected. The bearing „refurbishment anchors” are exclusively produced from stainless steel of resistance class III of the technical approval Z-30.3-6 or Z-30.3-19 (of Modersohn).

The ease of installation is also important for a refurbishment anchor. Experienced engineers and technicians of Modersohn can revert to an extensive repertoire on already tested fixing systems.

Refurbishment fixings

An important field of activity in building industry is the subject “building with existing structures” or also called “retrofit”. For the repair of bearing structures or building components Modersohn provides numerous special fixings. The term “refurbishment fixings „is a collective term for bearing and holding anchors with the aim to preserve existing, partly landmarked structure. Planning and delivery of refurbishment fixings necessitate much experience and knowledge about existing older structures. In case of doubt, tensile tests must be performed for plug- and connection anchor systems that can be accompanied by Modersohn as a partner of the plug manufacturers Fischer (Tumlingen) and Hilti (Kaufering). With regard to the load-bearing capacity and the general building material quality it is hard to determine whether the condition is suitable for a sufficient fixing.

Stainless steel housing

Stainless steel housings as cladding on machines and industrial plants are very often produced by Modersohn. In addition to the standard materials .4301 (1.4307 A2L) and 1.4404 (A4L) as well as 1.4571 (A5), Modersohn also delivers Duplex steels (made of stainless Lean Duplex steel), 1.4062, 1.4162, 1.4362, 1.4482, 1.4662 and Superduplex for highest demands on corrosion resistance. The weld edges are smoothly ground and the complete housing is perfectly refinished around with solid grinding plants so that housing seems to be from one cast. If a grinding and fleece look is too expensive, there is also the possibility of uniformly blasting small and large housings with finest abrasive glass beads in three bead blasting rooms.

By far, glass bead blasting is (like most of non-metallic blasting materials) the most careful and corrosion-technically best method since the blasting material is completely cleaned from ferrite residues using magnetic separators before reuse.

This is a big problem upon blasting with stainless steel granule since the martensite formation in the granules renders a cleaning impossible (permeability) and especially cinders of weld areas or thermal cutting methods are also blasted on the work pieces. Modersohn has a lot of experience in the production of housings and can quickly and precisely help with the development and the right material and surface selection in addition to the mounting of covers, hinges and seals.

Supporting brackets for brickwork

Supporting brackets for brickwork are hanger rods consisting of fastening heads (often adjustable in height) for anchor rail or plugs, diagonal pull element (e.g. gusset plate), bracing element against tensile force (e.g. pressure distribution plate on the gusset plate or on the pressure screw) and a support angle or support plate on which the façade brickwork is assembled. Modersohn supplies the supporting brackets system MOSO complete with technical approvals and verifiable structural analysis.

Suspension loop

In the area of window or door lintel of the facing wall, so-called “suspension loops” are hanged to the cut-off angle construction for a covered fixing of the brick-on-end course or concealed supports. Normally, these are bent wire parts mad of stainless steel wire of 3 or 4 mm that are bricked into the vertical joints. In addition, a cross-pinning of the brick-on-end course stones or concealed support stones are necessary. This facilitates to safely fix a bricked lintel also for larger window and door openings without that a support angle can be seen from below. Such a suspension loop can also hang on a brickwork reinforcement strip that extrapolates the bearing forces laterally into the supporting brickwork similar to the MOSO perforated tape.

In this case, the suspension loops are so-called „suspension brackets” or also “perforated tape brackets” with which the brick-on-end courses or concealed supports are clamped. Furthermore, Modersohn delivers different special variants of brick-on-end course fixings for bricked lintels for precast component part lintels.

Stainless steel

Stainless high-grade steel or stainless steel have the same meaning and signify a stainless high-alloyed steel material with at least 10.5 % of chrome and maximum 1.2 % of carbon within the area of “high-grade steels”. But the term “stainless” is to be understood as a value term under normal atmospheric conditions. So that no corrosion would develop, stainless steel additionally needs oxygen and moisture from the environment for forming the protective passive layer (chromium oxide, chromium hydroxide). Of course, there are applications and environmental impacts that can let corrode (less alloyed) stainless steels. Therefore, it is always important to seek expert advice with regard to presently about 120 different types of stainless steels. For further questions, consult Modersohn. Wilhelm Modersohn (member of the Executive Board of the information agency Edelstahl-Rostfrei in the steel center in Düsseldorf, Germany) and Prof. Dr.Ing. Wolf-Berend Busch, Chairman of the Executive Board of DVS Westfalen, Germany) can answer your specific questions (possibly per E-mail).

Stainless steel

A subgroup of „stainless steels” that disposes of a special high resistance against many environmental impacts producing natural corrosion. Stainless steel is a value term for which it is assumed to that the material is resistant against impacts occurring in the atmosphere compared to most of them. The alloy element Cr (chrome) is very important for these stainless steels designate as high-alloyed stainless steels.

The prerequisite for forming of only a few nm (nanometer) thick so-called “passive layer” ((chromium oxide/chromium hydroxide layer) for stainless steel are at least 10.5 masses % chrome, maximum 1.2 masses % carbon and the impact of oxygen and moisture from the surrounding atmospheric air. Contaminations, for example through salts (chlorides) and the lack of oxygen or moisture can strongly reduce the resistance so that “stainless” steel corrodes again and forms brown rust. In case of uncertainties regarding the right selection of the material and the assessment of environmental conditions, an expert must be always consulted. In such a case, please apply to the information office Stainless Steel in Düsseldorf, Germany, www.edelstahl-rostfrei.de

Stainless steel trays

For many years, Modersohn has produced “stainless steel trays” for industrial purposes, often for the storage of hazardous substances. In addition to drip trays for castor tanks in the nuclear power area, also collecting trays for painting halls of a large aircraft manufacturer or simple drip trays for production machines were produced so that no oils or cooling emulsions seep away in the concrete. System tray production, however, has a high share for the storage of hazardous substances, where Modersohn completely checks the trays with the proof of the German Water Resources Act (WHG) and leak tests (dye penetration method or vacuum method). Very big trays often mean a room lining. Experienced welders of Modersohn are welding the cladding parts prefabricated in the plant on site.

Scaffold anchorages

The stable fixing of mounting scaffolds is only possible with special holding anchors especially for large or high buildings. These fixings remaining permanently in the façade and subjected to tensions are basically made of stainless steel in clam-shell façade construction.

“The scaffold anchors for facing brickwork” are designed with an internal threaded sleeve for which only the mouth of in the joint area of the brickwork façade protrudes. It is optically hardly visible because it is closed with a colored cover cap in line with the wall mortar.

Only if a scaffold is erected or facade works, a ring bolt is screwed in that created the connection to the scaffold. Modersohn also offers "MOSO scaffold anchorages" in a heat transfer optimized form in order to avoid thermal bridges.

Spacers for façades

“Spacers for façades” is a designation from lightweight façade construction. The existing air gap and/or insulation layer behind the cladding is crucial for a so-called double-skinned façade. With the relatively light cladding elements, the “spacer” as a “fixing anchor” primarily provides stability with wind and snow loads and for a well adjustable and simple assembly. These fastening systems are increasingly produced from stainless steel and not from aluminum as they used to be. The reason is a more favorable heat conductance value for stainless austenitic or Duplex steels. Whereas aluminum is estimated with a λ (lambda value [W/m*K]) of 150, we have estimated a lambda value of 15 for the envisaged stainless steel grades. For comparison, ferrite steel (normal steel) must be estimated with λ = 45.

Modersohn is specialized in processing stainless Duplex steels (Lean Duplex steels) for such spacers and can also considerably reduce thermal conductivity cross-sections trough a high strength of these materials. This facilitates further cost savings.

Stud welding

This is an arc welding method in the area of joint technology, in which power flows via the contact between work piece and welding component using the method of arc ignition welding or tip ignition welding. Through the material resistance, this power heats the contact surface so far that the steel or metal surfaces melt with each other. In this way, at Modersohn head bolts are applied on anchor plates in the arc ignition method, and smaller threaded ends are applied to plant components in the tip ignition method. The advantage of this welding method is a small heat transfer into the work piece and a high economic production speed.

Support anchor connection systems

Is the general designation for a fixing system that absorbs the complete load of mounted structural components. As a rule, it serves as a description of the mechanical connection of different building materials, especially in the double-skin façade.

Support bracket

Support brackets are bearing anchors for the clam-shell facing brickwork façade. The forces of the facing formwork are laterally diverted into the displacement base (mostly concrete) via a mostly height-adjustable support anchor head by means of a removable wedge plate and a cantilever gusset with pressure point (also removable pressure screw). They can be designed as “single support bracket” or “angle support bracket”. As the name suggests, the single support bracket is a bearing anchors for an individual load application point. The single support brackets arranged in a line on a so-called support level bear the force of the facing formwork (façade) via the hardened stone composite. The angle support bracket consist of at least two support anchors heads (load application points) being connect via a continuous, normally firmly welded angle. This is the advantage of the angle support bracket compare to single support bracket, because load application points on the support level can be saved with an appropriate detail planning. This also saves material costs, mounting work and unpreferred heat transfers.

Based on its standardization, the single support bracket can be flexibly applied and is normally available in the standard load levels from stock at Modersohn. Furthermore, Modersohn has the CE marking, type tests and the technical approval Z-21.8-1892 for bearing anchor heads and pre-cast lintel fixtures Z-21.4-1907.

Support anchors for brickwork

The term support anchors must be considered in a combination with the term “fixing anchor”. A “support anchor“ is a fixing absorbing the complete dead load of the structural component and a certain part of externally acting forces, such as for example traffic weights, wind or snow loads. They mainly care after vertically acting forces. Against this, a fixing anchor shall only absorb the dead weight and certain part of additional externally acting forces, for example saving against tilting away, if a concrete precast plate is vertical to a foundation. Therefore, they essentially look after horizontally acting forces. Both anchor types are often commonly used for fixing a structural component. Modersohn produces support anchors for brickwork in form of brackets (brickwork brackets) or also called support brackets. Typical fixing anchors are for example: handrail panels, air layer wire ties or scaffold fixing anchors.

Staircase profiles

Modersohn produces stainless steel profiles (at least as angle profile 40/40/4 mm) with non-slip treat edge (R12) for concreting in concrete stairs. The MOSO staircase threaded profile is also an edge protection and stands out due to durability, especially in the area of the tread edge milled as toothing. Such tread edges on concrete stairs are ideal for the external area with a high movement of persons, for example at universities, schools and public buildings. The profiles are produced in lengths of 6000 mm and can be ordered fixlength depending on the stair width. Also round stair forms (convex, concave) are possible. In this case, the profiles are suitably rounded on a profile bending machine. Anchoring is done using flat anchors or head bolt anchors depending on the edge reinforcement of the staircases.

The stairs are concreted on the head, so the step protection angle on the bottom of the formwork can be connected or sticked (hot glue). A mounting to the nail holes is also possible, but it is often not requested because of the nail hole optics. The staircase tread profiles can be also produced in brass or bronze (hard bronze).

Substructures for façades

Façade substructures are a collective term for all fixing and supporting anchor elements behind the cladding. As a rule, the term substructure means a connected system-based profiled structure and less an arrangement of single anchors. The expectation is that such a substructure also provides a considerable degree of adjustment or rather adjustability for the concrete fixing situation. For heavy-load façades (brickwork façades, precast concrete facades), especially for façade areas with difficult fixing subsurfaces, Modersohn offers such profile systems. These are for example wind post systems or Attika fixings. These systems guarantee a high stability and adjustability.

In addition, Modersohn also produces substructures for solar module cladded façades according to customer specifications.

Threaded sockets

In civil engineering, normally a thick-walled tube sleeved with internal thread made of full material or hollow steel. The origin comes from tube connection technology. Modersohn produces them, but predominantly for tension anchorages made of round steel or threaded rods. Some variants have an inspection hole in order to ascertain whether both thread ends are screwed in far enough and meet centrically. A threaded socket serves for the connection of threaded rods or double ends but not for tightening sockets. See clamping sleeve. Threaded sockets are available as hexagon brass coupling or circular sockets. There is the heavy or thick-walled design compared to the thread sockets that have been produced from thinner tubes or tube sleeves with pressed socket.

Tube support

Modersohn fabricates special construction for wall and ceiling fixing of pipelines. The support anchors or rather bearing components of these systems are “tube supports” and are produced from plate or tube constructions. Following customer specifications, special clamps including screwing are included in the delivery as accessory. Modersohn has a store of threaded rods with a length of 3000 mm, of M 5 – M 42 in stainless steel A4 or D4 (Lean Duplex steel). With this, also simple tube suspensions with an extended adjustment possibility can be produced.

Related terms: tube fixings, pipeline fixings, tube holders, tube supports, clamps

Threaded sleeves

"Threaded sleeves“ are internal thread fasteners which are predominantly produced from round tubes. Thus, the wall of the threaded sleeve is relatively thin, but the production as standardized or serial parts is relatively cheap. As an alternative, there are the corresponding more thick-walled and thus, more load-bearing threaded sockets. The threaded sleeves serve for the screw connection with double-sided or continuous sleeve. As open threaded sleeves with unilateral sleeve they are welded with other steel parts or applied with the unilateral shat end, or perforated end as transport and lifting fixture in precast concrete parts. Furthermore, there are numerous other application fields in addition to the building industry. In addition to threaded sockets, Modersohn delivers various types of threaded sleeves in stainless steel.

Wall connecting systems

In the meantime, connecting systems for brickwork are produced in a wide range of variants. This concept certainly has origin for wall connecting anchors. They consist of perforated flat steel that has a fixing head on one side. The perforated flat end serves for insertion into the horizontal joint of the brickwork wall. The head of the hammer head is very often punched and can be slided into a mounting or anchoring rail. This facilitates a continuously adjustable holding fixture in height from concrete to brickwork so that the wall connecting anchor can be inserted precisely fitting into the horizontal joint of the brickwork wall to be connected. If a hammer or hook head bolt is welded using a U washer and nut. Modersohn often produces both variants corresponding to the project requirement. Such wall connecting anchors are often applied for wind posts and Attika facing anchors.

Wall anchors

In the meantime, the term wall anchor is a collective term for all brickwork fixings. This reaches from wall ties or brick tie anchors for the connection of brickwork walls up to visible cross or decorative anchors on needling or tension anchors in monument restoration. In order to receive concrete indications for a product specification, information should be found in advance in the internet or specialist brochures of fixing suppliers. The origin is the so-called “wall anchors” as a visible force distribution on the outer façade in order to dissipate the forces of the outer brick wall drifting to the outside (in the past mostly soft and porous natural stones) via needle anchors or tension rods into the inside of the bearing structural component. These “wall anchors” can be often seen in form of decorative elements, cross anchors or so-called St. Andrew´s cross on churches, domes or castles. Modersohn also produces the classic “wall anchors” from stainless steel.

For this purpose, stainless Lean Duplex steels are very suitable since they can be better coated with a black color for example compare to austenitic steels. The adhesion of colors, varnishes or also the foundations is considerably better on the ferritic-austenitic mixed microstructure of Duplex steels.

Welding company

Modersohn is a certified welding company with the manufacturer qualification class E, also for dynamic loads. The prerequisite is the monitoring by one welding engineer of whom Modersohn has employed two of these specialists. Prof. Dr.-Ing. Wolf Berend Busch (Chairman of the Executive Board of DVS in Westfalen, Germany and lecturer at Bielefeld University of Applied Sciences ) and Dipl.-Ing. Jürgen Matzelle (manager of product development for heavy-load fixing systems in our own Engineering Office for Structural Analysis) work as welding engineers. In addition, Rüdiger Gottwald (site manager) is continuously in production as welding expert and auditor. Modersohn also processes numerous special materials such as full austenites with the grades .4529, 1.4539, 1.4547 or also Duplex steels such as 1.4062, 1.4162, 1.4362, 1.4462, 1.4410 etc. For this reason, Modersohn has many process tests and special approvals. From very small welding constructions up to welded trusses with a unit weight up to 5 tons and up to a length of 14 meters, everything is possible in the assembly halls.

The material qualities are tested using X-ray fluorescence devices. At Modersohn, also light elements up to Al (aluminum) or S (sulphur) can be measured using the new devices. If requested, a measurement report can be attached to the delivery. In addition, Prof. Busch in the laboratory of the University of Applied Sciences or at the laboratory of DVS can quickly and simply perform special weld tests (for ex. section images), mechanical investigations or spectroscopic tests for very light alloy elements such as C (carbon).
