ABSTRACT:
A prefabricated structural panel for use in constructing the walls and/or roof of a building, which comprises two laterally spaced, longitudinal rails, preferably of pressure-treated wood, each of which has a lengthwise extending channel formed in the side facing the other rail, the channel preferably having sides that converge toward the bottom; and each rail also having narrow slots formed therein along the top edges of the channel sides. Each of the longitudinal rails has a stepped configuration on the side opposite the channel, which interlock with a companionate stepped configuration of the rail on the next-adjacent panel. A plurality of ribs extends perpendicularly between the rails, and their ends are shaped to fit snugly down into the channels. On opposite sides of the ribs are panels of sheet material such as plywood, plastic laminate, sheet metal, fiberglass reinforced plastic and the like, the edges of which fit snugly into the slots. A plurality of battens is provided on opposite sides of the panel, each batten bearing against the outer surface of the sheet material directly over one of the ribs. A plurality of fasteners joins the assembly together, some of the fasteners being driven through the sheet material into the rails and into the ribs, and others being driven through the rails into the ribs, others being driven through the battens and sheet material into the ribs, and still others being driven through the rails into the rails of the next-adjacent panels.
