Abstract (en)
[origin: CH706630B1] The method involves connecting carbon fiber-reinforced polymer tapes (4) with steel girders (3) of a steel structure i.e. iron bridge (1), at end regions in a traction-force fit manner. A lifting element (7) is arranged between the polymer tapes and the steel girders. The lifting element is vertically driven to the polymer tapes in a region between end anchorages (5) for causing traction force tensioning between the end regions of the polymer tapes. The polymer tapes are installed at the steel girders over a length of the steel girders. The lifting element is a hydraulic, pneumatic, electrical or mechanical actuatable lifting element. An independent claim is also included for a steel structure.
