Abstract: A building and method and apparatus for making a building at a job-site location is disclosed. The roof, side walls and end walls are made of similar skin and frame panels that are roll-formed on the job site, cut to length, have holes formed therein and are crimped to form bends in the roof and side wall panels to form interfitting portions at the corner of the roof and side walls. The panels are placed on a framing jig and seamed at connecting flanges and gussets are secured at inside corners to form a roof and side wall building section. These building sections may be a single skin panel and frame panel or multiples thereof. A multiple of two is shown. A roof truss may be fastened to the roof section for wider buildings. The framing jig is adjustable in size and shape to form buildings of different heights and widths. The framing jig shown is lifted by actuating hydraulic cylinders and a formed building section is seamed to a previously raised building section.

Abstract: Siding panels for covering the exterior wall of buildings mutually define a tongue and groove interfit which facilitates installation by placing the weight of an upper panel on an underlying lower panel instead of requiring an installer to hold the panel in place against gravity. Mounting nails are used in combination with the tongue and groove interfit to positively lock the tongue of one panel into the groove of the underlying panel. Nail placement is controlled by the relative placement of nail slots and hammer abutment surfaces formed on each panel. Because the panels must be pivoted in place and held in place by the overhanging siding nails, it is virtually impossible for the installer to make a mistake that results in an upper siding panel coming loose from the siding panel below.
