Abstract: Wall and floor connection arrangements. In various embodiments, a first a joist rim is coupled to the flanges of at least some vertically extending studs such that an upper rim flange of the first joist rim is substantially coplanar with a portion of an upper track of the wall. A second joist rim is coupled to another lateral flange of at least some of the vertically extending studs such that an upper rim flange of the second joist rim is substantially coplanar with a portion of the upper track and the upper rim flange of the first joist rim. A plurality of first joists may be coupled to the first rim and plurality of second joists may be coupled to the second rim. A floor deck may be received on the upper track as well as the upper flanges of the first and second joist rims.

Abstract: Various floor and wall constructions are disclosed. One embodiment includes a second vertical wall supported over a first vertical wall. One or more joist rims may be attached to the first vertical wall and pluralities of joists may be attached to the joist rims. Decking material may be supported on the plurality of joists. The second vertical wall may be fabricated from spaced second studs that extend between a top track and a bottom track. The bottom track comprises a web and two upstanding legs. The ends of the second studs serve to define open areas within the bottom track between the respective stud ends. A cementitious material may be applied onto the decking material and into the open areas within the bottom track to form the floor surfaces and barriers within the open areas.

Abstract: Various building components and building construction techniques are disclosed. One embodiment comprises a joist end bearing condition wherein a joist rim is supported on a support structure adjacent to a bearing wall and attached thereto. Joists are attached to the joist rim and noncombustible board may be supported on the joists to form a floor surface. Other embodiments include metal joist rims that also function as headers for walls and headers for window and door openings in walls. Various methods of constructing walls from prefabricated panels formed from cold-formed steel components are also disclosed.
