Abstract
A hinged metal web member for use in forming a truss or joist assembly. In one embodiment, the web member includes a pair of leg members having connector plates at the upper and lower end portions. Each connector plate has a plurality of teeth struck therefrom, with all of the teeth extending from a common side of the web member. The leg members are joined at their upper end portions by a hinge which allows the leg members to be folded together for shipping and storage, then opened to assume a V configuration when forming a truss or joist, A series of such web members may be hingedly connected to provide a web assembly of the required length and configuration. The hinge connection should be sufficiently strong and rigid to allow the web member to be utilized under conditions to be encountered in truss assembly, yet sufficiently pliable that the hinge may be snapped or broken apart to obtain a web member of the desired length.
