Abstract

Improvements in expandable spigot anchors of the type fixedly adapted to be secured to a pre-drilled hole in a concrete body or the like, characterized in that improved anchoring comprises: an elongated member of steel having a cylindrical body, a tang threaded into one of the ends and an expandable section at the second end; the expandable section is grooved in axial arrangement, with dome rings and an end undercut rim, an axial central cavity, an expandable lug with a conical tapered central portion, located between the respective ends, a recessed portion at one end of the plug adapted to be introduced into the cavity during the placement of the anchor and drive the tapered part inside the cavity, and a support flange placed on the second end of the block, of a diameter substantially identical to that of the body.
