ABSTRACT:
A series of rectangular roof panels and rectangular wall panels each include inner and outer corrugated sheet metal skins or skin portions which are rigidly secured by fasteners to opposite sides of formed sheet metal longitudinally extending spacer members rigidly connected by formed sheet metal laterally extending spacer members. A formed sheet metal box-type or fabricated ridge beam and a series of fasteners rigidly connect the inner skin portions and spacer members of the roof panels on opposite sides of the ridge to transmit tension forces, and a compressive wedge and fasteners rigidly connect the outer skin portions, and spacer members of the roof panels for transmitting compression forces. Inclined inner attachment plates and fasteners rigidly connect the inner skin portions and spacer members of the roof panels to the inner skin portions and spacer members of the wall panels, and outer attachment plates and fasteners rigidly connect the spacer members of the roof panels to the outer skin portions and spacer members of the wall panels to form a building structure which has substantial total strength and can be easily and quickly erected without the use of a crane. In some buildings, each of the roof and wall panels may also be formed from a single metal sheet which forms inner skin portions and outer skin portions connected by integral right angle side or web portions, and each panel may have a Z-shaped lateral configuration. Longitudinally spaced and laterally extending sheet metal spacers connect the outer skin portions to the side or web portion of each panel, and longitudinally spaced and laterally extending elongated tie members rigidly connect the inner skin portions of all the assembled panels.
