Abstract: A roof structure supporting a roof comprising a truss and a joist supporting the truss, the joist having two elongated wooden beam members on the bottom of the truss connected with beam tie members comprised of a pair of congruent truncated mirror image parallelograms forming hexagons with mutually facing and abutting portions. Each beam tie member is connected to outer sides of top and bottom elongated wooden beams and is adjacent to the next beam tie connected to outer sides of top and bottom elongated wooden beams. The tied beams allow use of smaller, less expensive beam members yet providing good truss support in a joist.

Abstract: A roof truss having laterally extended portions compared to standard size roof trusses for supporting a roof over a longer span compared to the span of a standard size truss. The extended portion has a supplemental purlin outside of the outermost web member of a standard size roof truss. The supplemental purlin transmits roof load force through a K truss or half-K truss with the upper portion of the K truss fastened to the supplemental purlin and a lower portion fastened to the roof truss extended bottom chord. Use of the supplemental purlin and K-truss architecture eliminates the need for sloping web members in the truss extended portion thereby saving material in truss construction while utilizing standard size truss templates and assembly jigs.
