ABSTRACT:
A truss assembly and attachment member for use in constructing truss assemblies. The attachment member includes an intermediate leg with first and second connecting plates disposed at opposite ends of the intermediate leg. Each of the connecting plates have a plurality of teeth extending generally perpendicular from the connecting plates. The intermediate leg has at least one groove extending from the same side as the sharp projections of the connecting plates and extending substantially the entire length of the leg between the connecting plates. This groove is deeper in the proximity of the connecting plates than in the center of the leg midway between the connecting plates. The leg also has a pair of side flanges projecting from both its outside edges and extending in the same direction as the groove. The depth of the side flanges varies along their length with the lowest depth being in the proximity of the connecting plates and the highest depth being in the proximity of the midpoint of the flanges located between the connecting plates.
