ABSTRACT:
A device for interconnecting two precast concrete objects, such as sections of a vertical column or a horizontal floor panel, which includes two mating joint components, one of the joint components being adapted to be mounted on each of the precast concrete objects, the two mating joint components being constructed of stronger concrete than the precast concrete objects and having mating surfaces which are smaller in cross section than the confronting surfaces of the precast concrete objects. In one embodiment of the invention, a plurality of tightening bolts extend between the two mating joint components. Also, in one embodiment of the invention, one of the mating joint components includes an outwardly extending console for the purpose of joining and supporting a beam or slab.
