ABSTRACT:
A hinged building truss, such as a roof truss, includes elongated wooden structural members connected by a double hinge joint. The joint has a central elongated flat plate having first and second pivots located toward respective ends of the elongated plate. First ends of first and second flat plates overlap first and second ends of the central flat plate and rotate in the plane of the plates at the first and second pivots, respectively.
The first and second plates each include a plurality of teeth, struck from second end areas of each plate, for fastening each plate to a face of a structural member to be pivoted. The structural members can thus be rotated about the pivots. The length of the elongated plate between the overlapping portions of the first and second plates is sufficient to accommodate sheet sheathing attached to each of the structural members when the double hinged joint is in folded position with the structural members substantially parallel and adjacent to each other.
