ABSTRACT:
A system for the edge-lifting of a horizontally disposed concrete slab either for transport or tilt-up operations, and embodying components which, after positioning in the slab form, become embedded in the slab after the wet concrete is poured and has become set or hardened. Such components include a horizontal reinforcing bar which extends through the edge region of the slab at a low level and imparts reaction force to a slab-lifting anchor bolt thereabove through the medium of a hanger clip at the time that the slab is lifted. The anchor bolt is fixedly positioned in the slab form and the hanger clip is hung on the anchor bolt and serves to support the reinforcing rod therebeneath in cradle-like fashion preparatory to a concrete-pouring operation for slab-forming purposes. The hanger clip of the system obviates the necessity of creating an upward offset in the reinforcing rod and hanging the rod directly on the anchor bolt at the point of the offset.
