Abstract: A recess former (130) is adapted for forming a recess (133) around the head of an anchor element (131) which is embedded in an edge of a concrete slab during casting thereof. The recess former (130) has an outer curved surface extending from a flat base surface. The outer surface has a hole at its apex to allow the anchor (131) to extend out of the recess former (130). A web (137) is located at the outer surface and has a channel (138) which is adapted for positioning of shear reinforcement means. The web (137) forming an air gap after the recess former (130) is removed from the recess.

Abstract: An anchor device (10) for the edge lifting of a concrete slab (11) is disclosed. The anchor device (10) comprises an anchor element (12) with a shank (14) partially embedded in the concrete slab (11) with one end of the anchor element (12) having a lifting head (15) positioned a small distance inwardly of the edge (16) of the concrete slab (11) within a recess (17) form in the edge (16) of the slab (11). Shear reinforcement bars (18) are also partially embedded in the slab (11) and partially positioned within the recess (17). The portion of the shear reinforcement bars (18) which is positioned within the recess (17) is spaced between the head (15) and the concrete of the slab (11) in the direction of lifting.
