Abstract
A space frame system built from rectangular tubing comprisingtwo substantially parallel planar chord frames laced together by many diagonal struts. The planar frames are of a rectangular grid pattern, both of the same grid dimensions, each made from continuous chords in one direction and tie chords one grid dimension long in the other direction, all the chords being disposed in one plane without overlap. Each frame has a position aligned with but out of registration with the other by half a grid dimension each way so intersections on one planar frame line up with open centers of the grids on the other. Diagonal struts run from intersections on one planar frame to the nearest intersections on the other. At intersections, the chords and struts are bolted or welded to one or more flat and bent plates. The outermost surfaces of the chords in one planar frame may be left clear of bolts and plates, and skylights may be mounted thereon.
