ABSTRACT:
A truss for use as support for a sloped roof of a building. The truss can be a collapsible metal truss. A method for assembling the truss is described. Each of the of the rafter and beam can include a metal chord all which chords lie in a first plane. Each of struts can include a metal chord located in a second plane parallel to the first plane. There are pivotal connections between various members. The chords of the truss can be moved into a collapsed position for storage and transport of the truss. The chords can be hollow tubes of generally rectangular cross section. The pivotal connections can be nut and bolt connections. The rafter and beam chords can be connected at an eave end to each other by a metal member, and the truss can include an eave extension member. The truss can have chords which are coplanar with each other, each chord of the beam and rafter having a "U"-shaped cross section defining a trough, which trough of the beam opens upwardly and which trough of the rafter opens downwardly, opposing legs of each "U" forming outer walls of the chord on either side of a central plane of the truss.
