A pre-fabricated concrete slab system and method have matching rectangular male and female type slabs which fit adjacent to each other in a checkerboard fashion. The male slabs include spaced reinforcing rods extending longitudinally and transversely through the male slabs with the rods' distal ends protruding outwardly away from one or more side edges of the male slabs to form a plurality of male connectors. The female slabs include a plurality of corresponding female sockets on one or more sides of the female slab, each female socket receiving a corresponding male connector when dropped therein. Corresponding female sockets positioned on opposite side edges of the female slabs are interconnected by steel reinforcing bars in both the longitudinal and transverse directions in a configuration similar to the male slabs so that, when connected, a continuous tension reinforcement is established between male and female slabs in both the longitudinal and transverse directions.
A male and female connector system for interconnecting reinforcing elements embedded in a pair of mating concrete structures, each of said concrete structures having an upper surface and a side edge, said connector system comprising a reinforcing element in one of said mating concrete structures having an end projecting beyond the side edge of said one mating concrete structure with an enlarged head thereon to form a male connector, and a female socket fixture connected to a reinforcing element in said other concrete structure and positioned along the side edge of said other concrete structure for receiving said male connector through a top of said female socket fixture which is open to said upper surface.
A male and female connector system for interconnecting reinforcing elements embedded in first and second mating concrete structures, each of said first and second concrete structures having a generally planar upper surface and a side edge substantially perpendicular to said upper surface, said connector system comprising:
