Patent

CA 2163272

An adjustable length steel joist has been developed which offers advantages in building construction compared to the present open web joist of fixed length. The proposed joist can be made in half lengths which can be joined together at the construction site by means of a bolted connection. This feature greatly facilitates building con- struction and shipment. The joist which is constructed from a tubular zig zag shaped web and two straight top and bottom components made from sheet metal is light in weight and easily assembled during manufacture.
