4 KE transport anhors General KE transport anhors - Transport double walls more seurely The Produt KE transport anhors are used to eret and transport wall setions both during the prodution of the prefabriated part and at the site of onstrution. The KE III model is designed for popular panel sizes and the KE IV model for panels with speifi requirements. The variety of dimensions and the novel design make the KE transport anhor an unrivalled produt tehnially, eonomially and in relation to safety that learly inreases flexibility during the onstrution of prefabriated parts. Features GS mark (KE III) for maximum possible safety Graduated bearing loads for eonomi planning Quiker and simpler to install for a problem-free prodution proess Position an be planned independent of the formwork girders for optimum solutions tehnially and eonomially Additional omments The KE III is produed from 14 mm diameter steel and the KE IV from 16 mm diameter steel. The anhors an be supplied in widths of 120 to 360 mm. The minimum onrete overing on the inside side of the shuttering is 10 mm for the KE III models and on the outside 20 mm. For KE IV transport anhors a minimum onrete overing of 20 mm inside and outside must be maintained. 4
5 KE transport anhors Produt range for better solutions KE transport anhors the more seure and eonomi way to transport or eret wall setions during the prodution of the prefabriated part and at the site of onstrution. Two designs are available for different installation types: KE transport anhor model A The standard design. Positioned at the entre of gravity of the wall panels. Suitable for stationary produtions/systems. Available as KE III and IV. * KE IV is designed with 2 stirrups * * KE transport anhor model B For quik loking into the formwork girder The 90 stirrup leg makes it easier to seure the transport anhor to the formwork girder e.g. by means of spring steel binders. Can also be inserted at the point of gravity. Suitable for use in rotating systems. Available as KE III. 5 KE transport anhors - Transport double walls seurely

8 KE transport anhors Planning If more than two anhors are provided a ompensating hanger or similar load distributing devie must be used. For transport reasons, setions in exess of 3.00 m in height must in pratie be turned at the site of onstrution. To this end the setions are to be put down flat and then raised to the upright position. The design riteria an be found in the assembly and usage instrutions approved in the design speifiations. Mounting reinforement must be verified. The anhor spaings must be planned so that the wall an be lifted at its entre of gravity: Distane between enters KE III: e 300 mm Distane between enters KE IV: Distane to edge KE III: Distane to edge KE IV: a 200 mm e 600 mm a 400 mm The wall panels must be designed with a minimum reinforement of Ø 6 / 250 mm in the anhor region. For the load ase transverse pull, suffiient edging must be provided between the free edge and the transport anhor or a formwork girder in the anhor region. * The transverse pull load of the KE III transport anhor an be inreased to 20 kn (onrete strength f 25 N/mm 2 ) if a 100 x 100 x 10 mm T-square is positioned on a width of 1.00 m per anhor. The square must be overed by an elastomer strip or shaft bearing. The steel setion must be seured against falling (e.g. weld the steel stirrup and seure to rane hooks with able). A square timber an also be used to protet the edge against damage aused by the rane hangers. This means a load inrease an only be obtained in a limited manner. 8
9 KE transport anhors Planning for better solutions Determining the transport anhor load When arrying out the planning, the regulations in the assembly and usage instrutions approved by the Professional Trade Assoiation for Building and Allied Trades must be observed and maintained. When determining the loads working on the transport anhors, the following must be observed whilst taking possible load overlap into onsideration: 1. Dead weight of the prefabriated part 2. Adhesion in the shuttering on lifting out 3. Impat loads 4. Number and arrangement of the transport anhors 5. Diretion of fore from means 1. Dead weight: To determine the dead weight of the wall setion, the load of the total volume of the shuttering is taken as 25.0 kn/m3. Additional mounting parts must be onsidered separately. 2. Adhesive fores: When raising the wall setion out of the shuttering, onsideration must be given to adhesive fores, the extent of whih depends on the type and omposition of the skin used. The following fores our for onventional materials: Oiled shuttering: q = 1.0 kn/m² Painted shuttering: q = 2.0 kn/m² Rough timber shuttering: q = 3.0 kn/m² An adhesive fore of q = 1.0 kn/m2 has already been taken into onsideration in the KE transport anhor load apaity tables. 3. Impat loads: When lifting, depositing and transporting wall setions impat stresses an our. Their extent depends substantially on the type of hoisting equipment used and an be a multiple of the panel weight. The ranes used in the prefabriation proess and also modern truk-mounted ranes have preision lifting equipment. Lifting load fators of f = 1.1 to 1.3 are to be applied here. A lifting load fator of f = 1.3 has already been taken into onsideration in the KE transport anhor load apaity tables. To determine the lifting load oeffiient under other basi onditions, the values must be determined aording to DIN : Number and arrangement of the transport anhors Prefabriated onrete parts do not always have the ideal geometry of a retangular panel with no reesses. Asymmetrial wall geometry and/or openings in the setion produe different loads for the installed transport anhors. In this ase, the distanes from the enters of the KE anhors to the wall setion point of gravity are inorporated into the determining of the respetive anhor load. Where there are more than two transport anhors, the mounting arrangement is statistially undefined. In this ase, a roller ompensation hanger is to be used. The higher number of anhors must not be used for the dimensional design without this measure. 5. Diretion of fore from the lifting means (diagonal pull) If hangers are not used for transport, there is inreased tensile load on the transport anhors. The maximum admissible angle of inlination α between the vertial and the lifting means is 45 degrees. The length of the lifting means is to be seleted aordingly. This angle = 45 has already been taken into onsideration in the KE transport anhor load apaity tables. The maximum admissible panel weight alters with the angle of inlination. 9 KE transport anhors - Transport double walls seurely
10 KE transport anhors Dimensional design Dimensional design of transport anhor systems When planning, the regulations in the assembly instrutions must be observed and maintained. Transport anhors for double walls must be dimensioned by an engineer for the fores atually ourring in pratie. The loads to be taken into onsideration are as follows: α = angle of inlination β = angle of spead S = entre of gravity KE = KE transport anhor l = lifting means length The angle of inlination α must not exeed 45. To this end, the length of the lifting means is to be l e/1.41. Central pull = load in axial diretion of the anhor Diagonal pull = load distribution under the angle of inlination α relative to the vertial Transverse pull = load distribution at the end fae when double wall is set upright. Extreme ase Dead weight of the wall setion G = r x V r = onrete gross density 25 kn/m³ V = onrete volume of the two shutterings 2. Adhesion of the onrete part in the shuttering Ha = ha x A The shuttering adhesion Ha is absorbed by the transverse pull load apaity of the anhor F red. Where the shuttering is oarsely strutured, the adhesive fore inreases onsiderably. An adhesive fore of q = 1.0 kn/m 2 has already been taken into onsideration in the KE transport anhor load apaity tables. A = adhering shuttering fae Shuttering type: ha Oiled shuttering 1 kn/m² Smooth timber shuttering 2 kn/m² Coarse timber shuttering 3 kn/m² 10

Impat load/lifting load fators F red = F admi / f Lifting Gear Tower rane for onstrution Lifting load fator f 1.3 Truk-mounted rane 1.3 Loading bridges, gantry rane 1.3 The redued anhor resistane F red inludes the redution through lifting load fators of a onventional tower rane, truk-mounted rane or gantry rane. If other lifting means are used, the lifting load fators will be higher. These are to be determined to DIN : A lifting load fator of f =1.3 has already been taken into onsideration in the KE transport anhor load apaity tables. Exavator, depending on the driving operation Number and arrangement of the transport anhors F Av = G x b / (a + b) F Bv = G - FA Openings in the wall setion or an asymmetrial geometry produe different loads on the anhors. F Av = F Bv = G = a = b = Vertial fore portion at anhor A Vertial fore portion at anhor B Weight of double wall at point of gravity Distane from entre anhor A to the point of gravity* Distane from entre anhor B to the point of gravity * 5.
