JORDAHL ® Anchor ChannelsQuality since 1907JORDAHL ® 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 introducedKahn’s reinforcing technology in Germany,developed the Anchor Channel by designing aC-shaped profile which was used as reinforcementand connection device at the same time.Today, with a century of experience in anchoringand connection technology “Deutsche KahneisenGmbH” with its brand name JORDAHL ® has developedinto an internationally renowned companyand a leader of research in anchoring technology,with a strong relationship to its customers.JORDAHL ® ProductsQuality made in Germany since 1907 and usedin projects around the worldState of the art and help customers buildefficiently to maintain quality standardsMade under strict quality control according toGerman and European approval requirementsEurocode compatible design & approved safetyconcept – ETA-09/0338 et al.Comprehensive range of superior anchoringand connection products with accessoriesISO 9001 based internal QA / QC processesWhichever type of construction is in progress,JORDAHL ® provides fully developed solutions ininstallation technology: for joining componentsto one another, for suspending loads or forconnecting devices.

Product RangeJORDAHL ® offers a broad range of products:JTA, the standard anchor channel product groupfor tension, angled tension and shear load.JXA, the toothed channels accommodating loadsin all directions.JGB, the anchor channels with welded rebar forinstallation in thin slabs.JORDAHL ® T-bolts, available as hammer head,hook head and toothed bolts.JTB, the easy solution for corrugated metal sidingand roof installation on concrete.JRA, the anchor channel with parallel weldedrebar anchors for extremly high dynamic loads.W-ProfilesTraditionally JORDAHL ® profiles are hot rolledfrom a billet. Therefore they are particularly freeof residual stresses. The geometry is optimized,well-suited for dynamic loads and high clampingforces from the T-bolts. Anchor channels madefrom hot rolled profiles are the preferred solutionfor curtain walls under high wind loads, elevators,heavy pipes under pre-stressed post-tensionedbridges, etc.K-ProfilesThe smaller JORDAHL ® profiles are cold formed in arolling mill which ensures dimensional consistencythroughout the cross sectional area. Cold formedanchor channels can be used for connecting precastelements, taking the dead weight of facadesor for attaching corrugated metal siding.SafetyworkTimeefficiencyLowcostSteel gradesMost profiles are made from carbon steel materialconforming to EN 10025 with a minimum yieldstrength of 235 N / mm 2 . Stainless steel grade A4conforming to EN 10088 is available upon request.Round AnchorsUnless custom design is required, anchors aregenerally cold-headed in a fully automa ted andmonitored production process.Simple toinstallNo risk offireGuide to ETA compatible Design5

JORDAHL ® Anchor ChannelsCurtain WallModern facade systems provide protection foroccupants of office and apartment buildings, aswell as the means for architects to create attractivebuildings on the metropolitan skyline. Completefacade elements can be pre-configured in the factoryand lifted with a crane into position. They canconsist of glass, metal, concrete and natural stoneelements. Intelligent solar power and air conditioningsystems can even be integrated. Curtain wallsystems guarantee superior quality, a safe workingenvironment, and fast on-site installation.JORDAHL ® anchor channels for glass and metalfacades are used to connect the longitudinal andtransverse profiles of curtain wall systems andtransfer the loads into the concrete structure. Theyare adaptable to suit any application and formattedin accordance with the design requirements.The various individual solutions are based on twobasic principles:The AdvantagesEasy installation and adjustability of theconnection systemInstallation close to the slab edgeSecure transfer of vertical and horizontal loadseven into thin floor slabs.

JORDAHL ® Anchor ChannelsPrestressed Bolted Jointsand Tightening TorquePrestressing Forces of T-BoltsIn connection technology, for the applicationsSuspended direct and stand-off installationStress in the channel longitudinal directionit 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 prestressingwith tightening torque is normally higherthan the external load.The applied prestressing force is dissipateddown to about 30 % by relaxation.Bolts made of stainless steel exhibit higherfriction than zincplated or HDG bolts. Therefore,stainless steel bolts produce lower prestressingforces.JORDAHL ® bolts are supplied ready for installation.They should not be additionally oiled ortreated with lubricants before the tighteningtorque is applied.The bolted joint may be prestressed only whenthere 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 rolledprofiles can be used. In order to prestress a boltedjoint with electro-galvanized (gv) bolts or stainlesssteel bolts, we recommend to use the tighteningtorques according to page 38.T instT instPrestressingforceExternal force =characteristictensile loadExternal force =characteristictensile loadHot rolled profile, hook headbolt and washer ensureuniformly distributed surfacepressure and allow hightorque moments.38Guide to ETA compatible Design

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 clean galvanized (medium)and stainless steel (high) nuts and bolts. The recommendedinstallation torque may be increasedby 30 % without danger of reaching the yieldstrength of the bolts.Relationship between Prestressing Force andInstallation Torque for:Mild Steel Bolts Grade 4.6 and Stainless Steel Bolts Grade A4-50Prestressing Force [kN]60.050.040.030.020.010.0M 12M 16FrictionmediumlowhighM 20Profile TypeW 72/48W 55/42W 53/34W 50/30W 40/220.00.0 25.0 50.0 75.0 100.0 125.0 150.0 175.0 200.0T inst [Nm]Mild Steel Bolts Grade 8.8 and Stainless Steel Bolts Grade A4-70Prestressing Force [kN]160.0140.0120.0100.0M 16Frictionmedium80.0M 1260.0W 72/4840.0W 55/42W 53/3420.0W 50/30W 40/220.00.0 50.0 100.0 150.0 200.0 250.0 300.0 350.0 400.0 450.0 500.0T inst [Nm]lowhighM 20Profile TypeGuide to ETA compatible Design39

Double Toothed T-BoltThe Solution for Longitudinal Shear LoadsThe heads of JORDAHL ® double-notch toothedbolts JKB are equipped with 2 hardened teeth.The high strength grade 8.8 of the bolts allowhigh installation torque and consequently highpre-stress of the connecting parts. The two teethon either side bite into the massive lips of the hotrolled profiles.Temporary application will leave marks behind.This does not affect the anchor channel performanceor corrosion resistance.The mechanism works well for the double toothedbolts M20 and M16 in the profiles W 50/30,W 53/34 and W 40/22. The bite creates a mechanicalinterlock that guarantees full load capacity evenafter years of relaxation of the initial torque.

InstallationEfficient, Easy and FastJORDAHL ® supplies anchor channels in all desiredlengths. 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 accordingto the reinforcement/formwork drawings. Toprevent displacement during concrete pouring, thechannels are held in place:on wooden formwork by nails through the nailholes in the back of the profile, or by lateralbonding with hot melt adhesiveson steel formwork by bonding with hot meltadhesives, or by bolting on with JORDAHL ®T-bolts, or with magnetson the surface of a concrete slab by wiring theanchors to reinforcement bars or, if required,by means of special spacers spot welded to theanchors.ConcreteConcrete is poured, raked and vibrated into theformwork – around the anchor channel concretehas to be compacted using appropriate means.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.Guide to ETA compatible Design49

JORDAHL ® Anchor ChannelsSafety of Designfor Fastenings in Concrete – Based on CEN/TS 1992-4-3: Anchor ChannelsWith the European countries officially introducingthe CEN/TS 1992-4-3 standard for anchor channels,a completely new developed design conceptis now available to calculate the strength of anchorchannels cast in concrete. This concept is basedon the European partial safety design and theEuropean Technical Approval for JORDAHL ® anchorchannels (ETA-09/0338). It generally leads to animproved utilisation of connections withJORDAHL ® anchor channels and offers more flexibilityin the design.The following individual conditions can be takeninto account for the design of JTA anchor channels:Edge DistanceLength of channelLoad positioning along the channelConcrete StrengthAdditional reinforcementThickness of concrete memberThe consideration of the above mentioned influencesallow to tailor-made the design for thespecific needs of each project. The key-benefit ofthis design concept is to reach the optimum ofeconomic and technical efficiency.In order to keep the effort of the design as small aspossible JORDAHL ® has carried out thousands ofcalculations. Taking all theoretical failure modesinto account the results have been summarizedinto 2 sets of influences: load configuration andgeometry for steel and concrete. With the knowledgeof the corresponding strength and reductionfactors (see page 13 – 27) any static designer cando a hand calculation.THE EUROCODE DESIGN CONCEPT: F Ed ≤ F RdToday’s building structures are usually designedaccording to the concept with partial safety factors.The concept is published in the Eurocodes (EC)and was adopted by all national standardizationorganizations in Europe.The design verification according to EC2 (concrete)or EC3 (steel) takes place on the design level.The design method according to the Eurocode conceptis as follows: The design loads F Ed are loadsfactored with various partial factors dependingon the load characteristic (e.g. dead or live load)and probability of simultaneous occurrence (loadcombinations).The design loads are compared with the designresistance F Rd = F Rk /γ M where F Rk is the characteristicresistance and γ M is a specific partial factor forthe material property (e.g. concrete γ Mc = 1.5, rebarsteel: γ Ms,re = 1.15).In general the proof according to this safety conceptis stated as:F Ed ≤ F Rd orF EdF Rd≤ 1Both sides, load and resistance, require more effortfrom static designers than the simplified andmore uneconomic permissible loads design, as youcan see from the adjacent symbolic diagram.However, the procedure allows the designer totake different influences of load and material intoaccount and achieve a more constant and reliablesafety level.This state-of-the-art design for anchorage inconcrete is now available as JTA-JORDAHL ® anchorchannel software.50Guide to ETA compatible Design

With today’s knowledge of potential failure modesit is possible to achieve an efficient and economicdesign. However, it is imperative that all data forsuch a detailed comparison is available.concrete failuresteel failureThe resistances of JORDAHL ® anchor channelspublished in this catalogue are based on today’sknowledge of anchoring in concrete as stated inCEN/TS1992-4 and the European Technical Approvalfor JORDAHL ® anchor channels.
