US 4,673,309 A · Method and apparatus for anchoring cables of high-tensile steel wire

Abstract

A method and an apparatus are described for anchoring cables, bundles of parallel or standard wire, or the like, of preferably high-tensile steel wire. At least one end of the cable or the like is introduced into a fixed anchoring socket and sealed with a pourable material. In order for the anchoring apparatus to have improved properties under static stress, and in particular under great dynamic stress, without requiring additional structural safety features, while enabling lower-cost manufacture, it is provided that the bundle be twisted and the bundle or cable opened for some distance from the associated end in such a manner that the wires or strands extend uniformly all the way through the conical inner region of the anchoring socket. Further, a metallic casting material is poured into the anchoring socket between the opened wires or strands, and a direct metal-to-metal joint is established between the metallic casting material and the wires or strands of the cable or bundle.

Dependent claims

An apparatus for anchoring cables, bundles of wires or strands, or the like, of preferably high-tensile steel wire comprising:

at least one fixed anchoring socket having a front end and a back end and including an inner surface defining a cone, wherein an associated end of the cable or bundle is twisted open such that it forms a cone approximately identical to the cone defined by the inner surface of the anchoring socket;
a metallic cast body inserted between the opened or spread-apart wires or strands;
and
a perforated template disposed on the front end of the anchoring socket into which the spread-apart wires or strands can be threaded.
