Abstract (en)

[origin: EP0436859A2] In order to be able to carry out the arrangement of ribbed tensioning wires (5), which are anchored in the concrete by adhesive bonding, in a prestressed concrete sleeper independently of the space requirement of the drawing heads of the tensioning devices, it is proposed to anchor the tensioning wires (5) temporarily in an anchoring plate (2) and, by suitable design, to make the anchor plate releasable and recoverable. <IMAGE>
