に提案し、従来より実施している。(Problems to be solved by the invention) A truss frame material unitized from upper and lower chord members and a belly member is assembled in two directions in a mesh shape, and a purlin support material for receiving a purlin on the upper side is connected to mesh nodes. In a three-dimensional truss constructed by erection in one direction, in order to prevent buckling of the purlin support material with a large fulcrum distance, a support member is raised from the lower chord material of the truss frame material and connected to the purlin support material. The applicant has already proposed a three-dimensional truss having a structure in which the deformation of the purlin support material is restrained, and has been implementing it conventionally.

る。The structure of this space truss is to raise the support member from both sides in the direction orthogonal to this in order to enhance the restraining effect of the purlin support material, and to clamp the purlin support material by sandwiching the central part. Since it is connected to the node position of the lower chord, many members will gather at this node,
It is complicated to settle and assembly work is troublesome.

うな四辺形を基本形とする網目を構成する。The truss frame member A is formed by connecting the upper chord member 1 and the lower chord member 2 with the belly member 3 as shown in Fig. 2 -II, and is connected to the bundle member 4 arranged at the nodal position of the space truss. To form a mesh having a quadrilateral as a basic form.

両側から拘束する。As shown in FIG. 2I, the support member 6 rises from the central portion of the lower chord members 2 and 2 facing each other in one direction, and is connected to the central portion of the purlin support member 5 so as to be obliquely crossed in plan view. The material 5 is restrained from both sides.

材６の交点に接続され、例えば上下弦材1,2間にダブル
ワーレントラスをなして配置される。The lower part of the support member 6 is connected to the central portion of the lower chord member 2 so that the bending moment does not act on the lower chord member 2, and the abdominal member 3 partially supports the lower chord member 2 as shown in FIG. It is connected to the intersection of the members 6 and is arranged, for example, as a double warren truss between the upper and lower chord members 1 and 2.

この場合、束材４の中央部には一面内で４本の腹材３が
集合することになる。In this case, four belly members 3 are gathered in one plane at the center of the bundle 4.
