TRUSS ARCH FOR FABRIC COVERED BUILDINGS AND THE LIKE

摘要

The present invention provides a strong yet lightweight truss arch which cou ld 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 tubul ar 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 sa id 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.
