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. Achieved thereby, on the one hand, is the provision of an annular surface, formed by the circumferential constriction, to convey the prestressing forces to the part of the structure, in addition to the smaller face turned away from the first partial body. The specific compressive stress on the concrete of the part of the structure is thereby decreased. Thanks to this particular construction and given shape, the inventive force transfer body can be realized more easily, compared to bearing plates, poured anchor bodies or prior art anchor bodies.
Force transfer body for an anchorage, comprising a body having an abutting surface serving as the contact surface for an anchor head containing individual members of a tension tendon, wherein said body is concreted within a concrete part of a structure, the force transfer body comprising at least first and second partial bodies, said first partial body being essentially annular and having first and second surfaces, with said first surface forming the abutting surface, said second partial body being disposed adjacent said second surface of the first partial body and coupled to said first partial body, the second partial body having the form of a hollow body with an outer surface and an inner generated surface and the outer surface being divided into two essentially annular faces and an outer generated surface, wherein the outer generated surface essentially represents the shell of a truncated cone whose larger face is turned towards the first partial body and wherein the outer generated surface has at least one radially circumferential constriction, an annular surface being formed by the circumferential constriction which, in addition to the smaller face, serves to convey prestressing forces to said concrete part of the structure.
