Abstract: A series of spaced-apart light gauge cold formed steel studs underlie an elongated light gauge cold formed steel channel or box. A series of joist supports are connected to the channel and a series of joists, formed of a light gauge cold formed steel, are connected to the joist supports and extend outwardly from the box. Decking is supported on the joist. Concrete is poured into the channel to form a reinforced header or beam, and concrete is also poured onto the decking to form a concrete floor. Together, the concrete floor and header form a monolithic concrete structure that enables the joist to be misaligned with studs.

Abstract: A combination stud and bridging member for use in a metal wall. The stud includes a web and a pair of flanges with the web including first and second sides and having a depression formed therein. Adapted to engage or extend through the web, the bridging member includes first and second end portions. One end portion includes a concave shaped recess that when disposed adjacent the stud accommodates the depression formed in the web. Disposed on the end portion of the bridging member having the concave recess is a projection receiver. Disposed on the opposite end of the bridging member is a projection. In a wall structure, the bridging members are adapted to extend between the studs. More particularly, the projections of the bridging members extend through openings formed in the web of the studs and into the projection receivers of adjacent bridging members to form an interlocked relationship.

Abstract: A stud spacer for use in a wall structure. The stud spacer includes a pair of opposed projections. The respective projections of the stud spacer interconnect with similar projections from adjacent stud spacers to form an interconnected series of stud spacers that extend through the studs that comprise the wall structure. When connected, each projection extends through an opening in an adjacent projection and a locking surface or locking tab associated with one projection seats in or against a stop or seat formed in the other projection.
