Abstract
Abstract A prefabricated and demountable building structure is disclosed. The structure provides for ready transportation and quick and easy assembly and disassembly in a minimum of time without the necessity of having to provide various tools to assist in the erection or demounting. The unit consists of a floor assembly having a central floor disc and a number of floor segments which interlock with the disc and with adjacent floor segments. Wall segments which are generally rectangular in side view fit together to form a wall enclosure which interlocks with the floor assembly. A roof assembly consists of a number of individual roof segments which interlock with adjacent roof segments and also interlock with the wall enclosure. The roof assembly is capped by a suitable vent or bonnet arrangement to hold all of the various roof segments in sturdy relationship. The vertical edges of the wall segments are provided with outstanding flanges which form a double flange to receive a wedge clamp to hold adjacent segments securely together. The double flange increases downwardly in width to receive a tapering wedge clamp which is slid over the double flange. The roof segments are likewise provided with flanges on their side or radial edges which butt together to form a double flange with the double flange increasing in width inwardly to receive a tapering roof wedge clamp. A suitable door and/or windows may be provided in selected one of the various wall segments.
