Abstract
A sheet metal structural member for use in the formation of a cast construction panel which member, in turn, comprises a sheet metal web defining a linear edge along one side, and a zig-zag edge along the other side, the zig-zag edge defining wider regions, and narrower regions between the wider regions, and the web extending in a generally triangular fashion from one narrower region through a wider region to the next narrower region, edge formations formed around the zig-zag edge portions of the web and, recesses formed in the wider portions of the web. The apex of each of the wider portions of the web, which may be secured to a construction material to form a panel.
Claims6
A first sheet metal structural member comprising;
- a sheet metal web lying in a predetermined plane and defining a generally linear edge portion along one side, and a generally zig-zag edge portion along the other side, said zig-zag edge portion defining wider regions each having an apex, and narrower root regions between said wider regions, and said web extending in a generally zig-zag fashion from one said narrower region through said wider region to the next said narrower region;
- edge flange formations formed around said zig-zag edge portions of said web and extending at an angle to said predetermined plane;
- recess means formed in each of said wider portions of said web, said recess means extending generally from an apex of a said web to a root region of said web;
- flange means formed around each of said recess means, whereby to reinforce said web, and,
- generally triangular indentations formed in said root of said web adjacent said recess means, but spaced therefrom, said triangular indentations being defined by a first generally linear base side, parallel to said linear edge portion of said sheet metal web, a second side, extending from said base side at an angle, and a third generally curved side extending from said base side, said sides meeting one another at generally curved junctions, and said second and third sides defining on either side thereof respective root portions of said web, located between said edge flange and said indentations.
