Abstract
A conical wedge for use in gripping a multiply rope or cable, especially concrete-reinforcing tendone, is circumferentially divided into a plurality of complementary parts each of which has, for at least part of its axial length, a deformation produced by pressing its circumferential edges towards its central axial plane so as to displace its interior surface adjacent said edges inwardly thereby increasing contact with the wires of the tendon. Preferably the region of deformation is confined to the narrow axial end of the wedge.
Claims2
A tendon-gripping assembly comprising a tapered wedge for gripping a multi-ply rope or cable, wherein the wedge is circumferentially divided into a plurality of parts surrounding an axial aperture for the rope or cable, each of the said parts having, for at least part of its axial length, opposed inwardly curved side edge portions, and a sleeve for receiving in its interior said parts of said tapered wedge, said sleeve having an inner tapered surface of the same inclination as and engaging exterior surfaces of said wedge parts including regions of said exterior surfaces which are situated between said inwardly curved side edge portions of said wedge parts, the exterior surface regions of said inwardly curved side edge portions of said wedge parts being situated inwardly of and spaced inwardly from the inner surface of said sleeve.
