Abstract: The present invention is an insulated modular wall system for quickly and efficiently constructing buildings of one or more stories. Included in this modular wall system is a plurality of building pans, each having a pair of flanges for interlocking adjacent building pans. Some of these flanges are configured to compensate for dimensional variations that are inherent in each of the building pans. If not compensated for, these dimensional variations can result in excessive stress when a plurality of adjacent building pans are interlocked. Included in the invention is a unique method for supporting convention floor boards, and a unique arrangement for creating a gap for electrical wires and the like.

Abstract: A multi-use metal building comprises a skeleton composed of vertical posts connected to upper and lower horizontal longitudinal girders, thus forming a frame ensuring transverse and longitudinal stability.In the horizontal plane, the skeleton comprises self-supporting metal trough elements modulated to the same width as the posts, with corrugated cross section, these trough elements resting on the upper longitudinal girders of the frame and serving on the one hand as floor support and on the other hand as roof.The vertical walls (posts, upper and lower longitudinal girders, outer skin made of asbestos and inner insulating partition) ensure the vertical stability in both directions.
