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.

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
JTB
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.
Profiled metal sheet connector channels facilitate
efficient connection of profiled metal sheets ( wall
and roof ) using self-drilling screws.
JZA
Cold-formed tooth profiles JZA absorb loads in the
longitudinal direction of the channel.
Most profiles are made from carbon steel material
conforming to EN 10025 with a minimum yield
strength of 235 N/mm2. Stainless steel grade A4
conforming to EN 10088 is available upon request.
JM
Round Anchors
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.
Unless custom design is required, anchors are
generally cold-headed in a fully automated and
monitored production process.

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.

Anchor Channels under Fire Loading
Anchor channels JTA and JXA can also be used in
components made of standard concrete with a fire
prevention 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 reinforced 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 ).

JRA – W 74/48 –
JORDAHL® anchor channels JRA consist of W 74/48
profiles with reinforced concrete anchors welded on
at the sides. The system may be adapted to many
areas of application. Other profile sizes can also be
provided with reinforced concrete anchors in special
solutions. They should be certified in the individual
case.
Load Capacity
JRA W 74/48 is suitable for absorbing extremely
high static and dynamic loads. The construction has
been tested by the German Federal Institute for
Materials Testing under the number 2.2/20247. On
the basis of experimental data with a load range of
Fo – Fu = 38 kN, with an upper load of Fo = 40 kN
these anchor channels have passed the long-term
stress capability test for fatigue load ranges of up to
30 kN.

Applications
JORDAHL® 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 ).
Installation
The 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.

All weights per metre for mill finish steel. For galvanized profiles: weights per metre × 1.10. For A4 profiles: weights per metre × 1.02.
The bolt load bearing capacity and the maximum point load bearing capacity must be noted ( see pages 13 and 29 ). The respective lower
value is decisive.

All load capacities are calculated elastically plastically in accorddance with DIN 18800 γF= 1.4 Deflection f < l/150 for steel.
Given more accurate knowledge, vertifications with partial safety margins must be carried out by the static designer.
We recommend an estimate of approx. 80 % of the values given above.
6)
The value only applies for St – A4 = FRd = 26.6 kN.

Notes
Bolt capacity may be limited by anchor
channel capacity
Observe profile load bearing capacity.
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 )

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.
Tinst

External force =
characteristic tensile
load
External force =
characteristic tensile
load
30
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.
Prestressing force
Hot rolled profile, hook head
bolt and washer ensure
uniformly distributed surface
pressure and allow high
torque moments.
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.

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:
1)
FEd ≤ FRd × ( 1 - M Ed/ M Rd )
FRd = permissible load ( see page 29 )
MRd = permissible bending moment
FEd = existing tensile load component
MEd = 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/mm 2 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 Installation
In 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.
For anchor channel
design according to
ETA-09/0338 please see

The 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 installation is finished, the corrosion protection is assured.

Stress in Channel Longitudinal Direction
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.

JORDAHL® 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 Plates
They are forged with an accurate shape and
therefore ensure that they do not rotate back.

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.
Material

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.

Brick Tie Channels
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 are
cast into the reinforced concrete. The corresponding 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.

Material
Channels 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.
Product Options
Joining channels can be obtained in various cross
sections. The masonry restraint channel
Kt 25/15-D consists of a channel with integrated
punched anchors which can be bent out. It ensures
secure anchoring even in freshly deshuttered
conditions. The associated brick ties of corresponding sizes can be obtained.

Profiled Metal Sheet Channels JTB
Profiled metal sheet channels permit fast, costeffective 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
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.
Material
Profiled 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 ).
JORDAHL® have a suitable channel connection
arrangement available for any application requirement or concentration of reinforcement.

Mounting and Installation
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.
End Anchors
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.

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.
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.

Edge Protection Angle JKW
JORDAHL® edge protection angles are supplied
with anchors ready to install. The round steel
anchors bent in a U shape may easily be fitted
into the reinforcing cage and do not conflict with
the corner reinforcement. JORDAHL® edge
protection angles are bent over at an angle of 92°.
This ensures good contact with the formwork and
a clean edge to the concrete. JORDAHL® edge

Pressure Bolts JDS
perm. F =
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.

Bolt
Constituents
The 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 Advice
In 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 a r ≥ 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.
