ABSTRACT:
A sheet metal structural shape for use as a stud or mullion in wall construction or a purlin or sub-purlin in deck construction which is symmetrical about a vertical bisecting plane having a central vertical web, two diagonal legs projecting downwardly from one end of the web forming an included angle of about 30.degree. to about 90.degree., each of the diagonal legs having a leg projecting downwardly at its extremity in a plane substantially parallel to the web, each of the parallel legs having flanges extending outwardly at their extremity, a closure side extending between the extremities of the flanges enclosing the area formed by the diagonal sides, parallel sides and closure side, and a stiffening member at the other end of the web. A wall structure utilizing a spaced series of the metal structural shapes with a wall material attached to the flanges of adjacent structural shapes. Also included in this invention is a double wall construction wherein a second wall material is attached between adjacent metal structural shapes to a flat face of the stiffening member of the structural shape. The wall structure is particularly suited to shaft wall construction. A poured concrete or a precast deck and a metal deck structure utilizing a series of the metal structural shapes of this invention providing deck structures of superior insulation, fire resistance and uplift resistance.
