ABSTRACT:
A unitary integral metal stud formed of sheet metal for constructing a fire-retardant wall and the wall structure formed of a plurality of studs and a pair of spaced-apart layers of gypsum wallboard panels in abutting relationship, the stud comprising a web having a pair of flanges defining a wallboard panel-engaging channel on one side, and a kerf-engaging flange substantially centrally locatead on the other side, and means extending from the web and having a supporting surface adapted to have a second layer of gypsum wallboard panels affixed thereto. A first row of panels is engaged by the channel and kerf-engaging flange, whereas a second layer of gypsum wallboard panels is affixed to the supporting surface extending from the roof. Additionally apertures may be provided in the web to inhibit heat conduction through the metal stud, and additionally to provide space into which the edges of the wallboard panels may dissipate heat if they should become hot, as for example during a fire. The resultant wall structure formed of the studs has a superior fire-rating.
