Abstract

In an interlocking beam construction in which hollow beams are notched and interlocked to define a completely rigid joint without fasteners, reinforcement inserts are slid into the beam to the notched area. The inserts are notched to conform to the notches in the respective beams so that the interlocking function of the beams is accommodated, but the weakness that would otherwise be produced at the joint due to the notching of the otherwise hollow beams is eliminated.
