Abstract

A truss section, comprising at least three parallel elongated structural members, said members defining a first cross-section, said members having two ends, said truss sections including means for end-wise coupling a plurality of said truss sections to assemble a longer load-bearing span, the improvement comprising an additional elongated structural member parallel to and structurally interconnected with at least two of said elongated structural members, said additional elongated structural member located substantially within said first cross-section, so as to define between said at least two and said additional elongated structural members, an elongated volume having a generally triangular cross-section.

1 . In a truss section, said truss section comprising at least three parallel elongated structural members, said members defining a first cross-section, said members having two ends, said truss sections including means for end wise coupling a plurality of said truss sections to assemble a longer load-bearing span, the improvement comprising an additional elongated structural member parallel to and structurally interconnected with at least two of said elongated structural members, said additional elongated structural member located substantially within said first cross-section, so as to define between said at least two and said additional elongated structural members, an elongated volume having a generally triangular cross section.  
     
     
         2 . In a truss section, said truss section comprising four parallel elongated structural members, said members defining a first generally rectangular cross-section, said members having two ends, said truss sections including means for end wise coupling a plurality of said truss sections to assemble a longer load-bearing span, the improvement comprising at least one additional elongated structural member parallel to and structurally interconnected with at least two of said elongated structural members, said additional elongated structural member located substantially within said first cross-section, so as to define with at least two of said elongated structural members, an elongated volume having a second, generally triangular cross-section.  
     
     
         3 . In a truss section, said truss section comprising four parallel elongated structural members, said members defining a first generally rectangular cross-section with four sides, said members having two ends, said truss sections including means for end-wise coupling a plurality of said truss sections to assemble a longer load-bearing span, the improvement comprising at least one additional elongated structural member parallel to and structurally interconnected with at least two of said elongated structural members, said additional elongated structural member located substantially within sa d first cross-section, so as to define with at least two of said elongated structural members, a recessed channel having a generally triangular cross-section in one of said four sides.
