ABSTRACT:
Two U-shaped beam half sections are attached together by having nesting ledges/receptacles on the flanges of the half sections. While the flanges of each beam half overlap against each other, the nesting ledges/receptacles hold the beam half flanges to fixed locations. Fasteners such as screws can be driven through the sides of the beam half flanges to fixedly lock the beam half sections to one another.
