Technical Examples
  1. An improved structural truss (3) and method of making same having oppositely disposed U-shaped channel chords (2) and struts (1) interconnected to one another at alternately extending apices (6) wherein the apices (6) form an inverted U-shape at a cross-section at the center of the strut (1). The ends (4) of successive segments of the unit lengths of the struts (1) and the chords (2) have holes for the insertion of a tapered pin (9), thus precisely controlling the length of successive trusses. The truss member (3) also has vertical load-bearing strut sections (17) at the end of each manufactured length of truss (3) to support a cantilevered section of chord (10).
