<p>"REVERSIBLE MECHANICAL COUPLING FOR TENSIONAL ANCHORAGES" Reversible mechanical coupling for tensional anchor ages, constituted by a cylindrical body inferiorly ending into a widened portion of conical shape capable of causing a set to be radially expanded of clamping levers pivoted around a linking ring controlled to move coaxially with the cylindrical body by a set of oleodynamic cylinders supported by said body, said clamping levers being kept into contact with said body by springs, and being in mechanical interference, in their expanded position, with a conical surface provided in the seat for the coupling. A set of vertical guides is moreover provided on the upper portion of the cylindrical body, to the purpose of guiding a set of wedges pivoted around an upper linking ring controlled to move coaxially with the cylindrical body by another set of oleodynamic cylinders supported by said body.</p> |
