Abstract:
1. An adjustable composite roof truss comprising: one or more roof truss members that include a pivot end, a connection end, a roof facing edge, an inside edge, and a pivot surface; one or more roof base members that include a receiving end, a connecting end, a top edge, a bottom edge, and a contact surface; and one or more central bodies, substantially parallelepipedic in shape, comprised of an expanded polymer matrix, having opposite faces, a first surface and an opposing second surface; wherein the roof truss members are pivotally connected to the roof base members by a pivot fastener inserted through a pivot opening positioned between a midpoint and the receiving end along the contact surface of the roof base members and a stator opening located between a midpoint and the pivot end of the roof truss members; wherein the roof base members include an embedded portion extending from the roof facing edge or the bottom edge respectively such that the embedded portion longitudinally extends across and into a central body; wherein the roof base members include an exposed portion longitudinally extending above the central body; and wherein one or more expansion holes are positioned along the embedded portion between the first surface and the second surface of the central body such that the polymer matrix expands through the expansion holes.
