Abstract: In a stressing anchorage for prestressing elements (2) in part of a structure, at least one part of an anchor head (4) consists of a mortar-like mass in the area in which bores (3) are disposed to accept frustoconical wedges (8). The frustoconical wedges (8) are made of steel. Since the mortar-like mass on which the frustoconical wedges are supported is more ductile, i.e., more workable than the wedges (8), the distribution of load from the wedges (8) to the anchor head (4) takes place in such a fashion that marked peaks of the load are considerably reduced.

Abstract: The force transfer body comprises a first, essentially annular partial body, preferably of cast steel, and a second partial body, preferably of a castable mortar mass capable of hardening. The second partial body is cast in one piece with the first partial body. An inner conical aperture is lined with a funnel-shaped plastic part, which overlaps at least a section of the first partial body. The first partial body has an abutting surface, turned away from the part of the structure, serving the firm contact with an anchor head containing individual members. The prestressing forces arising concentratedly with the anchorage are conveyed from the anchor head via the first partial body into the second partial body, and from there into the part of the structure. The second partial body is designed essentially frustoconical, the truncated cone extending, tapering, away from the first partial body. In the area of the outer generated surface of the second partial body there is a circumferential constriction.
