Abstract: An edge beam construction including two vertical perforated rolled shapes with webs inverted toward the center of the beam, and a bottom track having a flange disposed in a vertical position against bottom lips of the vertical rolled shapes. The three basic components of the edge beam are positioned so as to provide access for press joining tools. A building module manufacturing method utilizes the light gauge steel rolled shapes that permit industrialized, automated manufacture of floor, roof and wall panels for modular housing and commercial structures with integrated mechanical and electrical systems and rigid framing for road transport without trailers. The module manufacturing method includes a novel method of constructing and positioning a gable.

Abstract: A modular production system and method for producing wall panels of a modular building. The system includes a worktable, a plurality of telescoping tools mounted over the worktable, an overhead tram disposed adjacent the worktable, and a plurality of material supply bridges movably supported on the overhead tram so as to be movable over the worktable. The method of manufacturing a panel of a modular structure includes moving the first material supply bridge over a worktable to place panels of sheeting on the worktable, and then moving a second material supply bridge over the worktable to place steel members for the construction of a steel frame. A third material supply bridge is then moved over the worktable to apply adhesive on the sheeting in a pattern mirroring the steel frame.
