ABSTRACT:
A building structure supported by four central vertical columns fixed to the ground at vertices of a rectangle whose dimensions are much smaller than the dimensions of a floor of the eventual building. Segments of the columns constitute spreaders in upper and lower sets of trusses, each set including two pairs of trusses, the trusses of one pair being parallel to one another and perpendicular to the trusses of the other pair, and the upper and lower sets being vertically aligned. The chords of each truss extend outwardly from the columns, and the outer ends of the chords of the upper trusses are connected to the outer ends of corresponding chords of the lower trusses by generally vertical structural members by which to support, in cooperation with the columns, one or more floors of the structure above the bottom floor. Each column is the principal longitudinal member of a module havihg a rectangular transverse section throughout the major portion of its length and including members fixed to the column and projecting therefrom which, after erection, become segments of the chords of the trusses. Each module, when its column is horizontal, has lateral and vertical dimensions no greater than about 12 feet, or 3.5 meters, so that the modules can be safely and conveniently transported on a road or highway from a fabrication factory or the like to the site of the building, thereby minimizing expensive on-site work. The small size of the rectangle formed by the four columns permits inexpensive erection of the building even on steep slopes.
