JORDAHL® Connection Systems

Quality since 1907

JORDAHL® anchor channels are manufacturedby Deutsche Kahneisen GmbH in Germany. Thehistory of connecting steel to concrete begins in1907 with an invention of Julius Kahn, memberof a Chicago family of architects, whose “Kahnirons” opened up completely new possibilitiesfor construction with reinforced concrete. In 1913Anders Jordahl, a Norwegian engineer, who intro-duced 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 anchoringand connection technology “Deutsche KahneisenGmbH” with its brand name JORDAHL® has deve-loped 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

JORDAHL® offers following channels with correspon-ding 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 charac-terized 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.

Channel Overview

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 10025 with a minimum yieldstrength of 235 N/mm2. Stainless steel grade A4conforming to EN 10088 is available upon request.

Round Anchors

Unless custom design is required, anchors are generally cold-headed in a fully automated and monitored production process.

JORDAHL® supplies anchor channels in all desired lengths. To avoid fresh concrete from flowing intothe profile, JORDAHL® anchor channels are filledwith either polystyrene ( PS ) or polyethylene ( PE )foam. Both types can be removed easily.

ConnectingJORDAHL® anchor channels are installed accor-ding 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 ad-

hesives, 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.

ConcreteConcrete is poured into the formwork.

Removal of Foam FillerAfter the removal of the formwork the foam fillercan be easily removed by means of a hammer orother tools.

Mounting ConnectionsJORDAHL® T-bolts can now be inserted into theanchor channel slot at any desired point and,following 90° rotation, can be fixed by tighteningwith the appropriate torque. The slot on the bottomof the bolt must be transverse in relation to thechannel direction.

Material and Identification

Identification of JORDAHL® Anchor Channels

JORDAHL® anchor channels are permanently identified on the profile side and/or foam filling with type of profile and material specification.

Identification of JORDAHL® Anchor Channels JTA-CE

JORDAHL® anchor channels which are compliant with a European Technical Approval ( ETA ) show the designation “-CE”, see figure

Identification of JORDAHL® Bolts

JORDAHL® bolts are embossed on the bolt head with works symbol, type and strength class.

JORDAHL® anchor channels with round anchors are additionally embossed on the rivet head on the inside of the channel with profile designation or load class.

Anchor channels JTA and JXA can also be used in components made of standard concrete with a fireprevention requirement F90 or F60 to DIN 4102 Part 2 ( 90 or 60 minutes time to failure under fire ). Anchor channels in reinforced concrete beams stressed by fire on one side, reinforced concrete beams stressed by fire on three sides, and rein-forced concrete columns stressed by fire on four sides were investigated. In this case, only dead loads at right angles to the channel longitudinal axis and central tension/oblique tension and shear load are permissible ( no longitudinal tension ).

JORDAHL® anchor channels JSA consist of profiles with punched-out loops and associated anchoring straps made of sheet metal strip, which are installed on the building site and can easily be bent to shape by hand.

ApplicationsJORDAHL® anchor channel JSA should be used for fixing non-load bearing constructions. In this case, anchoring must be carried out only in normal reinforced concrete in strength class ≥ C12/15.

They may be used without further certification, if the load does not exceed 1 kN/m2. Slippage at the anchoring straps is to be expected under service load. The anchor channel

type is no longer approved by the German Institute for Structural Engineering ( DIBt ).

InstallationThe anchoring straps are pushed through the punchedout loops at spacings of 250 mm and bent to shape ( see figure ). There are punched-out loops at spacings of 125 mm, straps are installed only in each second loop. In any case, an anchoring strap must be arranged at the start and end of the channels. During installation, the edge distances from page 14 should be observed.

JORDAHL® channel-bolt combinations are extremely robust and simple to install. However, full service ability is achieved only if the fitted part is mounted directly with steel contact.

1) Observe profile load bearing capacity.2) The recommended tightening torques T achieve a

firm bolted fixing without overloading the components in the case of direct installation.Higher tightening torques may be required in the case of stand-off installation but require installation tolerances to be compensated for in order not to overload the concrete. ( Produce steel-steel contact )

Prestressing Forces of T-BoltsIn connection technology, for the applications Suspended direct and stand-off installation Stress in the channel longitudinal direction

it is important to prestress the bolted connectionsin order to prevent undesired loosening or slippageof 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 thefollowing points are taking into consideration:

In the short term, a force arising from prestres-sing 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 fric-tion than ZP or HDG bolts. Therefore, stainless steel bolts produce lower prestressing forces.

JORDAHL® bolts are supplied ready for instal-lation. 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 concretesurface, then the connection must be shimmed bymeans of a suitable washer ( see page 34 ).If this is not followed and the attached part isprestressed against the concrete surface, it leadsto residual stresses in the component. These cancause cracks or splitting of the concrete component.

Suspended Direct and Stand-Off InstallationFor 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.

External force = characteristic tensile load

External force = characteristic tensile load

Prestressing force

Hot rolled profile, hook head bolt and washer ensureuniformly distributed surface pressure and allow hightorque moments.

Prestressed Bolted Joints and Tightening Torque

The relationship between prestressing force andtightening torque can be seen from the graphsbelow. The prestressing forces vary strongly withthe friction in the thread between the nut and thebolt. Low friction causes high pre-load, typical forhot-dip galvanized bolts with lubricated nuts.

Friction is increased for electro zinc plated ( medi-um ) and stainless steel ( high ) nuts and bolts. The recommended installation torque may be increa-sed by 30 % without danger of reaching the yieldstrength of the bolts.

Permissible Bending Moments According to Approval Z-21.4-151 1)

1) The bending moment is based on the upper edge of profile and concrete.

2) In the event of bending with additional central tension or oblique tension, the bending moment must be superimposed:

FRd = permissible load ( see page 29 )MRd = permissible bending momentFEd = existing tensile load componentMEd = existing bending moment

Variable Bending Stress: In the case of curtain wall cladding with variable bending

stresses ( e.g. because of temperature changes ), the strain must not exceed A = 50 N/mm2 about the average M, based on the stress cross section of the bolt.

3) For the JTA K28/15 profile, the permissible bolt bending moment MRd must be reduced to 30 Nm in the case of a channel length L > 250 mm.

4) For the JTA K38/17 profile, the permissible bolt bending moment MEd must be reduced to 72 Nm in the case of a channel length L > 250 mm.

Stand-Off InstallationIn case of stand-off installation, a connection can be stressed by a bending moment as well as by tension and shear. Therefore, when choosing the bolt, the permissible bending moment must be considered.

The suitable washer is chosen in accordance with the table below.

Double-Notch Toothed Bolts

Design ResistanceThe two notches of the JORDAHL® notched toothed bolt avoid the slipping in channel longitudinal direction. This bolt can take a shear load parallel to the channel axis up to 7.5 kN with a global safety factor of 3.0. The application is intended only in galvanized hot-rolled profiles. When the installa-tion is finished, the corrosion protection is assured.

This application is documented by means of internal tests and is not part of the Building Approval. The load that can be absorbed depends on the anchor channel material, the bolt type and bolt material used and the tightening torque. The safety factor against slippage is approximately = 5.0. with the specified tightening torques. The specified loads in the channel longitudinal direction can be absorbed safely in conjunction with hot-rolled profiles and bolts in qualities 4.6 and A4-50.

For constructions with higher loadings in the channel longitudinal direction, JORDAHL® toothed channels JXA and JZA with Approval should be used.

AccessoriesLocking Plates

UseJORDAHL® locking plates can be used at any point on the JORDAHL® channel. 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 PlatesThey 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 PlatesHammer-Head locking plates can be used for the temporary fixing of components of lesser impor-tance. 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.

1) The load bearing capacities of the anchor channels according to ETA and the mounting profiles according to p. 24/25 must be noted. The respectively smaller value is decisive.

2) 17.3 kN permissible only in the W53/34 and W 55/42 profile.

JORDAHL® eyelet sockets are used to transfer tensile forces into concrete components, such as occur during the transport of fabricated parts. The eyelet sockets are cast into the reinforced concrete components.

To transmit a force, a reinforcing rod is needed as an anchorage. To do this, a rod with the largest possible diameter is fed through the transverse hole and bent over as per the drawing.

Restraining brick walls to reinforced concrete components

Brick tie channels and the associated ties ensure the permanent and secure connection of masonry or timber components to adjacent reinforced concrete background. The brick tie channels arecast into the reinforced concrete. The correspon-ding ties are introduced into the channels and connected to the timber or masonry. Masonry ties anchors are set into the mortar joint at intervals of about 25 cm.

MaterialChannels and ties are manufactured from stainless steel 1.4571/1.4404/1.4401 ( A4 ) for use in the external walling area. In interiors, it is possible to use hot-dip galvanized or pregalvanized steel products.

Profiled Metal Sheet Channels JTB

Profiled metal sheet channels permit fast, cost-effective installation of profiled metal sheets on reinforced concrete components. The anchors on such conventional channels are often difficult to insert in the pre-formed reinforcement cages. The profiled metal sheet channels JTB-AR and JTB-uni from JORDAHL® can be incorporated more easily in the existing reinforcement due to their slim anchor format.

Products

JORDAHL® have a suitable channel connection arrangement available for any application require-ment or concentration of reinforcement.

The types JTB-AR and JTB uni are suitable for all typical applications. They are recommended in particular for all reinforced components. Profiled metal sheet channels from JORDAHL® and the associated end anchors have Building Approval: JTB: Z-21.4-161.

MaterialProfiled metal sheet channels from JORDAHL® are produced from steel to EN 10 025, hot-dip galvanized with ≥ 50 µm zinc layer or from stainless steel 1.4571 or 1.4401/1.4404 ( A4 ).

Profiled metal sheet channels with inserted foam filling are concreted into the smooth and flat concrete surface of the load bearing component, flush with the surface and in the correct alignment. End joints between two fixing channels should be about 20 mm. Following the removal of the formwork, the profiled metal sheets are fixed to the channel by approved

connecting means, self-tapping screws or set screws. The profiled metal sheet must be fixed in the central third of the width of the rear of the channel. The axis of the bolt must be at least 2.5 cm from the end of the channel. The applicable Standards and Regulations for profiled metal sheets and fixing means ( DIN 18 807, Approval Z-14.1-4 ) must be observed.

Design Resistance FRd

Mounting and Installation

Hot-dip galvanized channels which are shortened individually are secured at the end by end anchors approved by the German Institute for Structural Engineering. The end anchors are connected 75 mm away from the end of the channels.

The connections means used for the end anchors can be selftapping drill screws ST 4.8 × 16 ZP to EN ISO 15481.

1) If the channels are arranged in such a way that the anchors of adjacent channels are offset centrally by at least 250 mm with respect to one another, the axial spacing aa may be reduced to 80 mm.

2) In the event that the permissible anchor force is not fully utilised, the edge spacing ar in the case of exclusively central tensile loading may be reduced to: red. ar = NEd / NRd × ar ≥ 5 cm NEd = existing anchor force, NRd = permissible anchor force

3) If the anchor force is fully utilised, the last anchor must be at least 90 mm away from the edge.

4) If the anchor force is fully utilised, the two end anchors must have a mutual spacing of at least 150 mm.

5) This is given by the geometry of the anchor and the required concrete covering c according to DIN 1045.

Pressure Bolts JDS

JORDAHL® pressure bolts are spacer bolts.They are primarily used in the installation of precast elements and are used to transmit compressive forces resulting from dead weight or wind loads. Tensile forces cannot be absorbed.

ConstituentsThe construction comprises a plastic sleeve with a nail plate, which is

arranged in the precast element or in the in-situ concrete,

a suitable bolt with nuts and washer made of stainless steel 1.4401( A4 ) nach EN 10088.

Application AdviceIn order to permit adjustment, the bolt should be arranged about 15 cm away from the edge of the fabricated part. In this case, the edge spacing from the upper edge of the plate should be ar ≥ 1.5× d ( d = plate thickness ). The fact that the forces are passed on in the concrete must be verified and ensured by adequate reinforcement in the force introduction region.

In combination with a tube socket ( see page 36 ), the pressure bolt joint can also be braced against inadvertent detachment.
