Abstract

A metal wall framing system for residental and commercial building construction. Channel shaped metal studs are secured between top and bottom channel shaped metal tracks without the use of separate fasteners by an arrangement of lugs, tabs and punched slots that hold the studs tightly to the tracks in a predetermined position.

Claims

1. A metal wall framing system for buildings or the like comprising a substantially channel shaped track member having a web portion and a pair of opposed flanges, a substantially channel-shaped stud member having a web portion and a pair of opposed side walls which are adapted to fit between said flanges of said track member, each of said flanges of said track member having an inwardly projecting lug and an inwardly and upwardly projecting tab, each of said sidewalls of said stud member having a slot and a notch formed therein adjacent to one end of said stud and designed to cooperate with said lugs and said tabs whereby as the end of said stud member is inserted between said flanges of said track member, said projecting lugs will engage said slots and said tabs will engage said notches and thereby lock the end of said stud member to said track member.

2. The metal wall framing system of claim 1 in which the lugs and tabs are formed at regularly spaced intervals along the length of the track member.

3. The metal wall framing system of claim 1 in which a substantially continuous inwardly projecting rib is formed in each flange of said track member parallel to the edges of said track flanges.

4. The metal framing system of claim 3 in which said lugs are formed as portions of said rib.

5. The metal framing system of claim 1 in which said tabs are inclined approximately 25* inwardly from said flanges of said track.

6. A metal wall framing system for buildings or the like comprising a pair of spaced parallel substantially channel shaped track members each having a web portion and a pair of opposed flanges, a plurality of substantially channel shaped stud members extending between said track members and secured thereto without the use of separate fasteners by a plurality of inwardly projecting jugs and inwardly and upwardly projecting tabs formed in said flanges of said track member which engage a plurality of cooperating slots and notches formed in the side walls of the ends of said studs.
