Abstract

The present invention is directed to a floor joist for use in a steel framed flooring structure. The floor joist has a U-shaped rectangular cross section with two parallel spaced apart flanges and a central web bridging the flanges and connected to one edge of each of the flanges. The central web has an extension on each end thereof, the extension extending beyond the flanges a distance of at least half the width of the flange.

Claims (3)

1. A floor joist for use in steel framed flooring structures, the joist comprising a metal joist having a generally U shaped rectangular cross section with two parallel spaced apart flanges and a central web bridging the flanges and connected to one edge of each of the flanges, the central web being an extension at either end thereof, the extension extending beyond the flanges a distance of at least half the width of the flange, the extension being bendable to allow it to butt against a web of a rim joist in a steel framed flooring structure.
2. A floor joist according to claim 1 wherein the floor joist is provided with slots between the web and the extension to allow the extension to be bent more easily.
3. A floor joist according to claim 2 wherein the extension extends beyond the web a distance of about the width of the flange.
