Abstract: A system for securing the fabric cover of a fabric covered building to the framework or foundation of the building. Along each side of the fabric cover, a tie-down member is fastened so as to extend substantially from one end of the fabric cover to the opposite end. This member is most conveniently a pipe inserted in pockets formed along the sides of the fabric cover, the member being exposed at intervals by cut-outs in the pockets. A plurality of individually adjustable tensioning devices, such as a winch or come-along, are positioned along each side of the fabric cover and attached at one end to the tie-down member where it is exposed by the cut-outs and attached at the opposite end to the framework or ground anchoring foundation. The tensioning devices exert an adjustable force on the tie-down members in the direction of the ground anchoring foundation.

Abstract: The present invention provides a strong yet lightweight truss which could be used in many applications, and is adapted particularly to a support framework for those fabric covered structures utilizing a fabric stretched over the top of the supporting framework. The truss can be made up into sections comprising tubular upper and lower truss members separated by a continuous tubular web. The coupling plates may be attached to each end of the sections such that the top edge of the coupling plate is below the upper side of the upper member, providing a smooth upper surface to the truss and eliminating wear points which could damage the fabric or other material stretched over or supported by the truss. The truss is easily transported and manufactured.

Abstract: The present invention provides a strong yet lightweight truss arch which could be used in many applications, and is adapted particularly to a support framework for those fabric covered structures utilizing a single piece of fabric stretched over the top of the supporting framework. The truss arch is made up of sections comprising tubular upper and lower arctuate truss members separated by a continuous tubular web. The coupling plates on each end of the sections are attached such that the top edge of said coupling plate is below the upper side of the upper member, providing a smooth upper surface to the truss arch and eliminating wear points which could damage the fabric or other material stretched over or supported by the truss arch. The truss arch is easily transported and manufactured.
