Abstract: An apparatus for supporting a concrete floor includes at least two joist assemblies. Each joist assembly includes a male frame member and a female frame member. A plurality of top joist clips retain a top of the male frame member against the female frame member and a plurality of bottom joist clips retain a bottom of the male frame against the female frame member. A plurality of bottom and top straps are used to retain a distance between two adjacent joist assemblies. A cross brace is used to retain a distance between two adjacent joist assemblies. A deck panel is retained and supported between two adjacent joist assemblies. Concrete is poured over a top of the deck panel to form a composite floor system. An exterior insulating finishing system is attached to the concrete, while it is still wet to form a composite wall system.

Abstract: An apparatus for supporting a concrete floor and a composite floor system constructed therewith comprises form panels supported between a plurality of joists, the joists including a shear connector at least partially embedded in the concrete slab of the floor system. Each of the joists may be formed of a double channel structural member, including a top chord to which the shear connector is secured, a bottom chord and a reinforced web.
