ABSTRACT:
A reversible mechanical coupling for tensional anchorages includes a cylindrical body having a widened portion of conical shape capable of causing a set of clamping levers to be radially expanded by pivoting around a lower linking ring controlled to move coaxially with the cylindrical body by a first set of oleodynamic cylinders supported by the cylindrical body. The clamping levers are kept in contact with the body by springs, and are in mechanical interference, in their expanded position, with a conical surface provided in the seat for the coupling. A set of vertical guides is for provided on the upper portion of the cylindrical body for guiding a set of wedges pivoting around an upper linking ring controlled to move coaxially with the cylindrical body by a second set of oleodynamic cylinders supported by the body.
