Abstract

Improvements in the anchoring system of wires, bars or braided cables for prestressed or post-tensioned concrete elements, characterized in that the tensioning rods or rods are fitted at their ends to retaining elements formed by two or more independent parts that have surfaces of contact with the rod of generators parallel to this and guidelines equivalent to those of said element, whose parts are formed by two cylindrical surfaces of converging axes, one of the cylindrical surfaces adapts to the bar, wire or cable to be anchored, and the another adapts and slides on one of the inner cylindrical surfaces with convergent axes of the outer part, so that when sliding the inner part with respect to the outer surrounding element, the adjustment pieces exert a uniform compression on the entire contact surface, both in the interior with the tensioning element, as in the outer contact with the surface of Sliding, which determines a perfect retention of the tensioning element without producing degolladuras in the same, nor be able to produce seizures by coupling.
