The use of ifting inserts with crimped end requires the compliance with this Installation Instruction as well as the General Installation Instruction. The Installation and Application Instructions for the belonging PHIIPP lifting devices (ifting loop with threaded end, Adapter for lateral tension, Wirbelstar, ifty ) as well as the data sheets of the be- longing PHIIPP accessories (Plastic nailing plates, Retaining caps KH etc.) must be followed also. The anchor may only be used in combination with the mentioned PHIIPP lifting devices. ifting inserts with crimped end are designed for the transport of precast concrete units only. Multiple use within the transport chain (from production to installation of the unit) means no repeated usage. A repeated usage is only allowed (e.g. ballasts for cranes) if it complies with the German approval (DIBt No.: Z-.3-).

Materials The ifting insert with crimped end consists of a galvanised precision steel tube in special quality. Alternatively the insert can be delivered in stainless steel SS 31. The end of the insert is crimped in order to avoid the penetration of concrete. A U-shaped stirrup is inserted through the cross hole to transfer the loads into the unit (acc. to Table 3 and Picture ). 17 PHIIPP GmbH, 3741 Aschaffenburg Technical changes and errors reserved February 17 2

With lateral tension the ifting insert with crimped end has only half of the load bearing capacity compared to axial loading. However, this is not a limitation because during tilt-up only half of the weight has to be lifted (please refer to the General Installation Instruction) PHIIPP GmbH, 3741 Aschaffenburg Technical changes and errors reserved February 17

4 Reinforcement Main reinforcement / Axial tension Additional reinforcement for diagonal tension When using ifting inserts with crimped end precast units must be reinforced with a minimum reinforcement (Table 3). This minimum reinforcement can be replaced by a compaudeoh VWHHO EDU UHQIRUFHPHQW $W WKH UVW WPH RI OIWQJ WKH concrete must have a minimum strength fcc of 15 N/mm². The user is personally responsible for further transmission of load into the concrete unit. If the ifting insert with crimped end is used under diagonal tension E >.5 an additional reinforcement according to Table 4 is required. Here the reinforcement for diagonal tension is placed contrarily to the tensile direction (Picture 7) and must have direct pressure contact to the anchor insert in the peak of its bending. Existing static or constructive reinforcement can be taken into account for the minimum reinforcement according to Table 3. Direct pressure contact Ødbr Øds Picture 7 Diagonal tension Position of the direct pressure contact between insert and additional reinforcement must be within the thread reach of the insert.

5 PHIIPP ifting insert with crimped end Reinforcement Additional reinforcement for lateral tension If an anchor is loaded by lateral tension where the inclination is J DQ DGGWRQDO UHQIRUFHPHQW V UHTXUHG (Table 5 or Table ). The reinforcement for lateral tension can be made as a single reinforcement bar (Picture ) or double reinforcement bar (Picture 9) as well as reverse reinforcement (Picture ). There must be direct pressure contact between the insert of the transport anchor and the reinforcement in the peak of the bending. ateral forces on threaded transport anchors are only possible with wall thicknesses d according to table 2. The reinforcement for lateral tension is installed in the front side of the wall contrary to the load direction. Tilting of walls can cause diagonal and lateral tension at the same time (Picture 9 and ). In this case only the reinforcement for lateral tension is required (reverse reinforcement or double reinforcement bar). The diagonal tension is already covered by using this reinforcement. b g Picture 9 Diagonal tension - double reinforcement bar b g Ødbr2 g FQ Øds1 Ødbr1 Øds2 2 Ødbr2 h2 1 Picture Diagonal and lateral tension Reverse reinforcement for lateral tension Ødbr1 Table : Reverse reinforcement for lateral tension (material B500B) (required if J h1 Picture ateral tension - single reinforcement bar During mounting the tilt-up or turn-over of a unit requires lateral reinforcement (single reinforcement bar according to Picture or reverse reinforcement for lateral tension according to Picture ). The double reinforcement bar for lateral tension (Picture 9) covers standard lifting directions. With lateral tension the mesh reinforcement (Table 2) must be applied as a mesh cap. In addition to the mesh cap longitudinal reinforcement must be installed as shown in Table 5 or Table. oad ØdS2 2 h2 Ødbr2 ongitudinal reinforcement Ø length Ø Ø Ø Ø Ø Ø Ø1 00 Table 5: Reverse reinforcement for lateral tension (material B500B) (required if J oad Øds1 h1 1 Ødbr1 ongitudinal reinforcement Ø length Ø Ø Ø Ø Ø Ø Ø1 00 Minimum element thickness of 0 mm is required PHIIPP GmbH, 3741 Aschaffenburg Technical changes and errors reserved February 17
