Device for tightening reinforcing elements in pre-stressed concrete structures includes tensioning means with mechanical drive to contact coupling member connected to reinforcement element and second coupling member connected to structure

摘要

The device includes at least one tensioning means (SM) having a mechanical drive and designed to contact with a first coupling member (K1) connected to at least one reinforcement element (V) on one side and with a second coupling member (K2) connected to the structure (B) on the other side. A swivel connection (S1 or S2) with at least one swivel axis (A) arranged at an angle to the tensioning direction (X) is provided in the path of the pre-stress force flow between the connection of the first coupling member with the reinforcing element, and the connection of the second coupling member with the structure.
