ABSTRACT:
A series of rectangular sheet metal roof and wall panels each includes inner and outer corrugated skin portions which are connected by web members or portions which may also be corrugated. A fabricated sheet metal ridge beam rigidly connects the inner skin portions of the roof panels on opposite sides of the ridge to transmit tension forces, and connects the outer skin portions of the roof panels for transmitting compression forces. Inclined inner eave attachment plates or panels rigidly connect the skin portions of the roof and wall panels, and other eave attachment members rigidly connect the roof panels and wall panels to form a building structure which has substantial total strength and may be easily and quickly erected without the use of a crane. Each of the roof and wall panels is prepunched and may be formed from a single metal sheet which has a single major corrugation or a Z-shaped lateral configuration. Longitudinally spaced sheet metal spacers connect the outer skin portions and web portions of assembled panels, and longitudinally spaced and laterally extending elongated stiffeners or tie members rigidly connect the inner skin portions and spacers of the assembled panels.
