Patent ID: 8209939

Claim:
A system for supporting a load across a plurality of non-intersecting beams; each respective beam of said plurality of non-intersecting beams having a web depending from an upper chord and a plurality of ribs extending generally perpendicular from said web integrally coupling said web with said upper chord; said upper chord being generally parallel with a chordal plane; the system comprising: at least one crossing member; each respective crossing member of said at least one crossing member intersecting a selected non-intersecting beam of said plurality of non-intersecting beams at at least one respective intersection locus; each said respective crossing member having a length and a width; each said respective crossing member presenting a substantially planar upper surface substantially along said length and said width; at each said respective intersection locus said respective non-intersecting beam presenting a channel structure configured for receiving said respective crossing member in a substantially nesting orientation when said respective non-intersecting beam and said respective crossing member are in an installed orientation; said respective crossing member including an integral support expanse configured for a substantially nestingly abutting relation with said upper chord; said respective crossing member and said upper chord being substantially coplanar at said upper surface at each said respective intersection locus in said installed orientation; at least one tension resisting member extending between two adjacent ribs of said plurality of ribs for resisting tension forces on said upper chord in said installed orientation.
