ABSTRACT:
A shoring beam extension and reinforcement assembly allows a user to removably connect a plurality of shoring beams together so as to customize a support assembly to a particular excavation site. In use, main shoring beams extending around the periphery of an excavation site are connected at the corners by corner connections and are connected along the longitudinal sides of the excavation site by the extension of reinforcement assembly. Additionally, the first and second connectors support a center shoring beam laterally across the excavation site. The assembly is provided with additional support by tabs extending from each of the first and second connectors. Reinforcing beams include tabs having apertures adapted to align with apertures in the tabs of the first and second connectors such that connecting pins may be inserted there through to connect the reinforcing beams with the connectors. Eyelets located on the first and second connectors provide a means by which the assembly may be supported.
