ABSTRACT:
A series of rectangular roof panels and rectangular wall panels each include inner and outer corrugated sheet metal skins 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. The inner skins and spacer members of the roof panels are rigidly connected across a ridge portion to transmit tension forces. The outer skins and spacer members of the roof panels form a pitch of less than twelve degrees and are rigidly connected across the ridge portion for transmitting compression forces. Inner attachment plates and fasteners rigidly connect the inner skins and spacer members of the roof panels to the inner skins and spacer members of the wall panels, and the spacer members of the roof panels are also rigidly connected to the outer skins 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 one embodiment, the roof panels are connected at the ridge by an upper tapered wedge member and a ridge beam disposed below the panels, and in another embodiment, a ridge beam is disposed between the panels. The roof and wall panels are constructed either with parallel skins or with tapering spacer members forming non-parallel skins. The spacer members within the roof panels may also be formed with open lattice-type crossing struts for minimizing weight in larger roof panels.
