Abstract
1496970 Anchor bolts; screw sockets HILTI AG 1 July 1975 [22 July 1974] 27613/75 Heading F2H In an expansible anchor in which coacting inclined thrust surfaces on an expansible socket and an expansion element cause radial expansion of the socket in a borehole upon axial movement of the expansion element, rolling bodies such as spheres or cylinders are positioned between the thrust surfaces to reduce friction. As shown in Fig. 1 spheres 3 are positioned between frusto-conical thrust surfaces 6 of the socket and guide grooves 9 in a frusto-conical thrust surface 8 of an expander bolt 2. Guide grooves may additionally or alternatively be formed in the thrust surfaces of the socket. In the embodiment of Fig. 2 the expansion element 12 is externally threaded and has a forwardly tapering thrust surface 20. In modifications of the Fig. 1 embodiment (Figs. 3 and 4, not shown) series of axiallyspaced spheres (28) are provided; and the spheres are replaced by cylinders (40) between flat inclined thrust surfaces. Where series of axially spaced spheres 56 are provided, the socket can, as shown in Fig. 5, be divided into separate axial sections 46 held together by yokes 48 and expansible by respective frustoconical portions 54 of the expansion element. The socket can be formed of segments held together by clips, or can be longitudinally slit at its forward end to allow for its expansion.
