2 JORDAHL Connection Systems Quality since 1907 JORDAHL anchor channels are manufactured by Deutsche Kahneisen GmbH in Germany. The history of connecting steel to concrete begins in 1907 with an invention of Julius Kahn, member of a Chicago family of architects, whose Kahn irons opened up completely new possibilities for construction with reinforced concrete. In 1913 Anders Jordahl, a Norwegian engineer, who introduced Kahn s reinforcing technology in Germany, developed the anchor channel by designing a C-shaped profile which was used as reinforcement and connection device at the same time. Today, with a century of experience in anchoring and connection technology Deutsche Kahneisen GmbH with its brand name JORDAHL has developed into an internationally renowned company and a leader of research in anchoring technology, with a strong relationship to its customers. JORDAHL Products Quality made in Germany since 1907 and used in projects around the world.

4 JORDAHL Connection Systems Easy Anchoring in Concrete JORDAHL anchor channels are a superior connection system for transferring loads in reinforced and unreinforced concrete components. Anchor channels are cast into concrete and support static and dynamic loads. They are especially designed for highly reinforced and slender concrete parts. Anchoring without damaging the concrete structure and reinforcement Good integration into heavily reinforced components Suitable for pre-stressed and post-tensioned structures Increased load capacity near reinforcement High fatigue resistance as well as loads resulting from seismic tremors and explosions Time efficient on-site installation Skilled labour not required for installation Installation with simple tools like hammer and wrench Small edge distances Easy to customize 15 different sizes for the most economical solution Adjustable in three dimensions No damage of reinforcement and floor heating Reinforcement can be taken into account when planning Greatest Safety Ensured Eurocode-compatible design and EU-wide ETA approval ( ETA-09/0338 ) and therefore international validity Design concept with National Building Approval Z , Z , Z , Z , Z Installation without damaging the body of the structure Verified safety through building approval of the products High load capacity even in delicate or highly reinforced components Independent of shrinkage and creep of the concrete component Suitable for installation in the compression and tension zone of the component safety work time efficiency low cost simple to install no risk of fire 4

5 Channel Overview JORDAHL offers following channels with corresponding bolts: JTA-W Traditionally JORDAHL profiles are hot rolled from a billet. Therefore they are particularly free of residual stresses. The geometry is optimized, well-suited for dynamic loads and high clamping forces from the T-bolts. Anchor channels made from hot rolled profiles are the preferred solution for curtain walls under high wind loads, elevators, heavy pipes under pre-stressed post-tensioned bridges, etc. JXA The toothed, hot-rolled JXA profiles absorb longitudinal forces due to toothing between the channel lip and bolt. JGB Anchor channels with W and K profiles are used to fasten railings with special anchors in narrow members. JTA-K Cold-formed JORDAHL profiles JTA-K are characterized by their consistent dimensions over the complete cross-section surface. They can be used, for example, to connect prefabricated elements that absorb the dead weight of facades. JZA Cold-formed tooth profiles JZA absorb loads in the longitudinal direction of the channel. JM Deutsche Kahneisen Gesellschaft mbh supplies mounting channels as W and K profiles in toothed form as well as non-toothed form. Perforated, unperforated and in many types of cross-section, they offer great versatility in use. JTB Profiled metal sheet connector channels facilitate efficient connection of profiled metal sheets ( wall and roof ) using self-drilling screws. Steel Grades Most profiles are made from carbon steel material conforming to EN with a minimum yield strength of 235 N/mm 2. Stainless steel grade A4 conforming to EN is available upon request. Round Anchors Unless custom design is required, anchors are generally cold-headed in a fully automated and monitored production process. 5

7 Installation Efficient, Easy and Fast JORDAHL supplies anchor channels in all desired lengths. To avoid fresh concrete from flowing into the profile, JORDAHL anchor channels are filled with either polystyrene ( PS ) or polyethylene ( PE ) foam. Both types can be removed easily. Connecting JORDAHL anchor channels are installed according to the reinforcement/formwork drawings. To prevent displacement during concrete pouring, the channels are held in place: on wooden formwork by nails through the nail holes in the back of the profile on steel formwork by bonding with hot melt adhesives, or by bolting on with JORDAHL T-bolts, or with magnets on the surface of a concrete slab by wiring the anchors to reinforcement bars or, if required, by means of special spacers spot welded to the anchors. Concrete Concrete is poured into the formwork. Removal of Foam Filler After the removal of the formwork the foam filler can be easily removed by means of a hammer or other tools. Mounting Connections JORDAHL T-bolts can now be inserted into the anchor channel slot at any desired point and, following 90 rotation, can be fixed by tightening with the appropriate torque. The slot on the bottom of the bolt must be transverse in relation to the channel direction. 7

30 JORDAHL Connection Systems Prestressed Bolted Joints and Tightening Torque Prestressing Forces of T-Bolts In connection technology, for the applications Suspended direct and stand-off installation Stress in the channel longitudinal direction it is important to prestress the bolted connections in order to prevent undesired loosening or slippage of the bolted connections. Higher-strength bolts (8.8) are not absolutely necessary for this purpose. Grade 4.6 and A4-50 bolts are also adequate if the following points are taking into consideration: In the short term, a force arising from prestressing with tightening torque is normally higher than the external load. The applied prestressing force is dissipated down to about 30 % by relaxation. Bolts made of stainless steel exhibit higher friction than ZP or HDG bolts. Therefore, stainless steel bolts produce lower prestressing forces. JORDAHL bolts are supplied ready for installation. They should not be additionally oiled or treated with lubricants before the tightening torque is applied. The bolted joint may be prestressed only when there is steel to steel contact. If the channel is set back behind the concrete surface, then the connection must be shimmed by means of a suitable washer ( see page 34 ). If this is not followed and the attached part is prestressed against the concrete surface, it leads to residual stresses in the component. These can cause cracks or splitting of the concrete component. Suspended Direct and Stand-Off Installation For these applications, cold formed and hot rolled profiles can be used. In order to prestress a bolted joint with electro zinc plated ( ZP ) bolts or stainless steel bolts, we recommend to use the tightening torques according to page 29. T inst T inst Prestressing force External force = characteristic tensile load External force = characteristic tensile load Hot rolled profile, hook head bolt and washer ensure uniformly distributed surface pressure and allow high torque moments. 30

31 The relationship between prestressing force and tightening torque can be seen from the graphs below. The prestressing forces vary strongly with the friction in the thread between the nut and the bolt. Low friction causes high pre-load, typical for hot-dip galvanized bolts with lubricated nuts. Friction is increased for electro zinc plated ( medium ) and stainless steel ( high ) nuts and bolts. The recommended installation torque may be increased by 30 % without danger of reaching the yield strength of the bolts.

As a result of a 90 degree rotation after being inserted or tilted in, the threaded hole is at the centre. Locking plates are preferably used for stand-off mounting with long bolts or threaded rods. Because of the hidden installation, they are not approved by the German Institute for Structural Engineering. Hooked-Head Locking Plates They are forged with an accurate shape and therefore ensure that they do not rotate back. In order to make installation easier, we recommend a thin strip of foam inside the channel, behind the locking plate. Hammer-Head Locking Plates Hammer-Head locking plates can be used for the temporary fixing of components of lesser importance. They clamp without a particular form fit like the hook-head locking plates. On request, we also produce captive strips suitable for fixed thread spacings.
