ABSTRACT:
A connector (10) is disclosed which serves the dual function of providing a threaded insert for threaded engagement with a lifting bolt to move the concrete casting and as a shear connection between the first concrete casting and a mating concrete casting. The connector (10) is cast within a first concrete casting (12). A threaded portion (18) is exposed at an edge of the casting which threadedly receives a lifting bolt. When the casting is being installed, an exposed reinforcing rod section (30) of the mating concrete casting is inserted within the threaded portion (18) and a grouting cavity (20) in the connector and the reinforcing bar is pressure grouted therein with epoxy, a metallic non-shrink grout or other suitable grout.
