Abstract
Abstract The specification discloses a truss having first and second wall columns and first and second roof elements. Knee braces connect the wall columns intermediate their ends with the roof portions intermediate their ends. A center cord spans the roof sections, the latter comprising pairs of stacked wooden elements arranged vertically edge to edge bridging the point at which the knee braces join the roof elements and the point at which the center cord joins the roof elements. The construction minimizes costs and wastage of materials, and uses standard commercially available lumber while providing for adequate strength.
