Abstract

Embodiments of the invention comprises a truss assembly and a method for assembling the truss assembly. The truss assembly includes V-shaped longitudinal supports forming corners of an elongated truss located at each angle of a polygonal axial cross-section. Open webs are fixedly attached between each adjacent V-shaped longitudinal supports extending the length of the elongated truss. The open webs have a plurality of bends in a same plane, and the plurality of bends are welded to a portion of the inner surface of adjacent V-shaped longitudinal members without having to place jigs or bracing to form the open web or to secure the open web to the two V-shaped longitudinal members. The elongated support truss may have a triangular cross-section, a rectangular cross-section, a square cross-section, a pentagonal cross-section, or the like.

First claim

open webs fixedly attached between adjacent V-shaped longitudinal members, the open webs extending at least a portion of a 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 the adjacent V-shaped longitudinal members.

2. The elongated support truss of claim 1 , wherein the polygonal axial cross-section is a triangular cross-section and the inner angle of the V-shaped longitudinal members is 60 degrees.

3. The elongated support truss of claim 1 , wherein the polygonal axial cross-section is a rectangular or square cross-section and the inner angle of the V-shaped longitudinal members is 90 degrees.

4. The elongated support truss of claim 1 , wherein the polygonal axial cross-section is a pentagonal cross-section and the inner angle of the V-shaped longitudinal members is 108 degrees.

5. The elongated support truss of claim 1 , wherein each of the open webs are welded to the V-shaped longitudinal members without having to place jigs or bracing to form the open webs or to secure the open webs to the adjacent V-shaped longitudinal members.

6. The elongated support truss of claim 1 , further comprising:
an end member fixedly attached at each end of the elongated support truss with a shaft extending longitudinally outwardly from the end member adapted to engage a drive to longitudinally rotate the elongated support truss;
solar panels attached along one side of the elongated support truss of polygonal axial cross-section, and
at least one rotatable drive capable of rotatably driving at least one of the shafts at the end of the elongated support truss to move the solar panels in relation to a change of direction of incoming solar energy.

7. The elongated support truss of claim 6 , wherein the outwardly extending shaft is located at a position other than the center of mass of the elongated support truss of polygonal axial cross section.

8. The elongated support truss of claim 6 , further comprising:
an A-frame operatively coupled to each end of the elongated support truss.

9. The elongated support truss of claim 6 , wherein the end member is a plate that is fixedly attached to each of the V-shaped longitudinal members.
