ABSTRACT:
A protective panel may be used alone or paired to form a protective structure to provide a protected space in an excavation by buttressing the upright walls of the excavation. The protective panel is constructed of a corrugated aluminum sheet that has alternating, oppositely opening, longitudinal channels. The end edges and the lateral edges of the sheet are rigidified respectively by a transverse and longitudinal rigidifying members. Mounting stations are located on one side of the protective panel and are formed by transverse support plates that extend across the top of a selected channel and that are reinforced by gusset webs to create a beam section. A brace assembly may mount to the mounting station and may support the protective panel against an upright excavation wall; preferably, however, a pair of opposed protective panels are interconnected and retained apart by a plurality of spreader beams extending between opposed mounting stations to create a protective structure in the form of a trench box. The protective structure may be supported by leg members that telescope into the transverse rigidifying members. Alternatively, the protective structure may be suspended from a wheeled carriage. A plurality of protective structures may be stacked and retained by interconnect pins. The protective panels may include inwardly oriented handles. An optional end panel with a specially configured latch structure is disclosed, and optional mounting stations and spreader beams are described.
