Abstract:
1. A modular building system for constructing a multi-story building, the system comprising: a plurality of prefabricated modular units, each modular unit comprising a horizontal concrete slab for forming a floor of the building, a concrete joist portion extending horizontally along a first edge of the slab, the joist portion extending below the slab and having a portion that extends horizontally beyond the first edge of the slab to form a receiving lip, a plurality of concrete columns positioned on top of the slab along the first edge, and a plurality of connectors installed in cavities formed in the modular unit, wherein the slab and the joist portion form a bottommost portion of each modular unit, wherein at least one modular unit of the plurality of prefabricated modular units further comprises at least one of (a) a raised floor positioned above the slab and (b) a dropped ceiling positioned below the slab, wherein at least one floor of the multi-story building is formed by arranging the modular units so that the slab of a first modular unit is positioned on the receiving lip of a second modular unit, and at least one additional floor of the multi-story building is formed by arranging the modular units so that the joist portion of an upper modular unit is positioned on the columns of a lower modular unit.
