いた。Conventionally, in this type of three-dimensional truss, when joining the joining points of truss beams and truss beams, joints are interposed at joints, and the ends of the upper and lower chord members of each truss beam are connected to the joints. The parts were joined by bolts, and the joint plates were straddled by straddling the upper and lower chords and bolted together. However, the upper and lower chords of the truss beams and the lattice members were integrally stopped For this reason, when they are transported, they are deformed or damaged, and when assembling them at an installation site, assembling them integrally is quite troublesome.
