<p>PROBLEM TO BE SOLVED: To provide a space truss, which has a rational structure without superposing members, can be manufactured easily with high accuracy and has high reliability at a low cost by ensuring horizontal rigidity without moreover using a special part or the like. SOLUTION: Upper chords 3 and lower chords 4 are disposed on the same perpendiculars and the upper sides of the upper chords 3 and the lower sides of the lower chords 4 are done in parallel, and planar trusses 2 in which post members 5 and diagonal members 6 are joined are installed among both the upper chords and the lower chords. The planar trusses 2 are crossed at right angles and disposed, and the lower chords 4 or the upper chords 3 are joined mutually to form V-shaped trusses 10. A plurality of these V-shaped trusses 10 are arranged, and the space truss is constituted by folded plate-shaped truss 11 in which the upper chords 3 or lower chords 4 of the adjacent V-shaped trusses 10 are folded and matched mutually.</p> |
