Abstract: A metal stud having a central web between a pair of opposed flanges includes an opening in the web through which a channel can pass. The opening has at least one straight edge and a centrally disposed bendable tab extending into the opening. The width of the tab is substantially less than the width of the opening. Bending the tab to a position at right angles to the web of the stud provides a surface to which the channel can be attached. A framework is disclosed which comprises a plurality of such metal studs having openings in their webs through which the channel is passed and then attached to the bent tabs.

Abstract: An elongate unitary wall framing clip and a wall spacing assembly comprising the clip in combination with a stud member are provided for forming a multilayer wall assembly. The multilayer wall assembly includes a base layer comprising plural backing panels and a secondary layer comprising plural secondary panels, with the base and secondary layers being spaced apart by plural stud members. The clip includes an elongate web portion having proximate and distal edges and first and second side surfaces. An elongate full flange portion joins the web distal edge and extends beyond each of the web first and second side surfaces. An elongate half flange portion joins the web proximate edge and extends beyond the first side surface of the web. A first channel for receiving an edge of a first backing panel of the base layer is formed by the cooperation of the web portion first side surface and the half and full portions extending therebeyond.

Abstract: I-beam studs of sheet metal have overlapped shaftwall portions having holes to provide for flow of cooling air along the overlapped portions to prevent failure of the studs from fire. First drywall sheets are mounted in the studs on the shaftwall sides thereof, and second drywall sheets are secured to the studs at the corridor sides thereof.
