Claim Text:
1. A joist girder construction system, comprising: (a) a pair of bi-planar sheets of structural material, each of said bi-planar sheets having two alternating series of vertical segments, each segment of each series, in horizontal cross-section, defining a planar base parallel to a base of a successive vertical segment of said alternating series of vertical segments, said planar bases of each segment of said alternating series integrally connected to each other by sidewalls; (b) respective upper and lower horizontal tracks, each defining in, transverse cross-section, a substantially U-shaped geometry, each track open-ended for enclosing and securing respective upper and lower edge areas of both bi-planar sheets of said pair thereof; (c) a plurality of vertical members, each of said members vertically disposed between said pair of bi-planar sheets and nested within opposing corrugations thereof; and (d) respective left and right tubular horizontal member defining in cross-section, a geometry of a polygon, an inner portion of each horizontal member having a partially cut-out lower surface proportioned for engagement about respective left and right edge areas of said upper track.
