Abstract
Abstract An elongated stud or beam, formed of sheet material, and provided at each end with protruding sharply pointed tabs. It is intended that the stud would be disposed between upper and lower horizontally elongated wooden, building construction members, with the sharply pointed tabs imbedded in said wooden members to resist withdrawal therefrom, and to further resist lateral displacement of the sheet material stud relative to the elongated wooden members.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
141 words
A building construction member formed from an elongated blank of sheet material and including, a web extending centrally, longitudinally of said blank, said blank having opposite longitudinal edge portions respectively bent at angles obtuse to the plane of said web to form a pair of panels conjoined by and spaced apart by said web, flanges formed by bending respective longitudinal, marginal edge portions of said panels, each at an angle substantially normal to the plane of said panels, said flanges occupying parallel planes, and being joined by and spaced apart by the interconnecting web and by said respective panels, said panels and said flanges being substantially co-extensive with said web, and said flanges being in substantial, mutual registration with each other, fastening means carried at each end of the construction member to secure said construction member in assembly in a building.
Claim 2
Dependent Claim
