Truss assembly and method for making the same

An elongated support truss having a polygonal axial cross-section, the elongated support truss comprising:

• V-shaped longitudinal members forming corners of the polygonal axial cross section, each of the V-shaped longitudinal members comprises an inner surface and an outer surface, wherein the inner surface of each of the V-shaped longitudinal members is located on a first side comprising an inner angle that is less than 180 degrees, and the outer surface of each of the V-shaped longitudinal members is located on a second side comprising an outer angle that is greater than 180 degrees, and wherein the polygonal axial cross section is a triangular cross-section;
• and
• open webs fixedly attached between adjacent V-shaped longitudinal members, the open web extending at least a portion of a length of the elongated support truss along each side of the triangular cross-section, each of the open webs comprising a plurality of bends in the same plane, the plurality of bends fixedly attached to a portion of the inner surface of each of the adjacent V-shaped longitudinal members.

A method for forming an elongated support truss with a polygonal axial cross-section, the method comprising:

• assembling open webs between three or more V-shaped longitudinal members;
• wherein the V-shaped longitudinal members form corners of the polygonal axial cross section, each of the V-shaped longitudinal members comprises an inner surface and an outer surface, wherein the inner surface of each of the V-shaped longitudinal members is located on a first side comprising an inner angle that is less than 180 degrees, and the outer surface of each of the V-shaped longitudinal members is located on a second side comprising an outer angle that is greater than 180 degrees;
• wherein the open webs are fixedly attached between adjacent V-shaped longitudinal members, the open webs extending at least a portion of the length of the elongated support truss along each side of the polygonal axial cross-section, each of the open webs comprising a plurality of bends in a same plane, the plurality of bends fixedly attached to a portion of the inner surface of each of the V-shaped longitudinal members.
