Consequently, not only the handling of each member such as the management and the transport of them is troublesome, but also the coupling work of the members needs much trouble. Consequently, it has been desired to decrease the number of members as much as possible, or to simplify the coupling work.

  • the diagonal members are formed by using bent rod members shaped in a letter V, the bent rod members having coupling portions at both ends and at centers of the rod members, as main members, and by arranging a plurality of bent rod members in a state of intersecting to each other and of intersecting with the chord members of both of the lattices diagonally at positions of the respective intersecting points, and by coupling ends of bent rod members intersecting with a bent rod member to a center of the latter bent rod member at each of the intersection points, and by coupling a straight line rod member with an end of a diagonal member at which the length of the bent rod members is too long in place of the bent rod member, the straight line rod member formed to have a length equal to one side of the letter V of the bent rod members, the straight line rod member including coupling portions at both ends thereof.
