ABSTRACT:
A supporting structure for modular building units comprising a pre-cast reinforced pre-insulated concrete slab. The supporting structure is a rectangular multi-bayed structural unit, suitable for use as a floor system or a roof, supported by composite pre-cast concrete beams integrated from the upper surface to the lower surface of the unit. At least a pair of pre-cast reinforced longitudinal beams run parallel to the length of the structure. Pre-cast reinforced composite crossbeams or purlins run in the transverse direction at regular intervals. The beams and purlins have integrated deformed reinforcing bar steel, and may include steel channel bottom reinforcement. An upper reinforcement of wire mesh is provided near the surface, welded to the reinforcing rods at intervals. The steel channel bottom reinforcement includes a plurality of spaced apart upright steel studs welded at regular intervals along the channel. In one embodiment, the beams and purlins create a series of structural recessed bays along the underside of the structure that include rigid polystyrene insulating foam for thermal and sound insulation as well as integral vapor barrier. In another, lower weight embodiment, a nonconcrete central foam core is provided, with a metal wire grid supported on each side of the foam core, with pre-cast perimeter beams and purlins.
