Abstract
Anchoring device for the harmonic steel wires used in the prestressing of load-bearing concrete structures, characterized in that it is formed substantially by "anchors" that retain the harmonic steel wires provided with heels at their ends and consisting of: A) a main ring provided with: a) a threaded central hole; b) certain outside diameter at a certain height; c) certain greater external diameter in the rest of its height; d) notches provided with a semicircular shape, arranged in all their circumference and, in almost all the height of the smaller diameter, equispaced in pairs, with a transverse placement flush with the surface where said notches are made. In the remaining part towards the greater diameter and through such part, there are holes of greater diameter and of such characteristics that each of them includes two of the small holes formed by coupling the notches or semi-holes existing in the two rings ; B) a secondary ring resting on the step formed by the different diameters of the main ring, and having: a) a height equal to that of the part of the main ring equipped with the smallest diameter; b) such an internal diameter adherently surrounding the part of smaller diameter of the main ring; c) an external diameter slightly smaller than the part of greater diameter of the main ring; d) semicircular notches equispaced in pairs over the entire extension of the inner face and coinciding with the notches in the surface of the part with the smaller diameter of the main ring; C) the notches in both rings, that is, the notches in the main ring facing outwards and the notches in the secondary ring facing inwards, when both rings are in their final position, will form holes through the rings. Which will pass the harmonic steel wires forming the necessary cable for prestressing the structure. (Machine-translation by Google Translate, not legally binding)
