PURPOSE:To improve structural efficiency and improve rigidity inside and outside the face by connecting trusses assembled with upper chords and a lower chord via horizontal chords, brace chords and lattices into a triangular solid with beams and brace chords. CONSTITUTION:Two parallel upper chords 1 and 1 and a lower chord 2 are assembled into a triangular solid via multiple horizontal chords 5, brace chords 4 and lattices 3, and a triangular space truss with short buckling length and good structural efficiency is constituted. Trusses are arranged in horizontal parallel rows at a fixed interval, and the trusses are connected by beams 5' and 5' extended with the upper chords 1 and 1. Intersections between the upper chords 1 and 1 and the beams 5' and 5' are connected by brace chords 4' and 4' while the arrangement and phase of the brace chord 4 of the truss are displaced by one measure, and a triangular space truss structure is formed. These trusses or truss structures are connected with angle steels, bending members and gusset plates as required.
