開発した。 In the three-dimensional truss constituting the Oharima frame, a structure in which a triangular lattice or a square lattice is constructed with truss-shaped frame members is known. By increasing the size of the grid, the number of on-site joints can be reduced.
Therefore, the number of times the frame material is lifted can be reduced. However, as the frame becomes longer, the problem of buckling of the upper and lower chords arises. Therefore, the applicant
As shown in No. 138203, we have developed a structure in which a buckling prevention material that also serves as a purlin support is arranged for a three-dimensional truss consisting of a triangular lattice. Furthermore, we have developed a structure shown in Japanese Utility Model Application Publication No. 123511/1983 for a three-dimensional truss consisting of a rectangular lattice with a buckling prevention material that also serves as a purlin support.

細を図示した実施例によつて説明する。 In the case of forming a rectangular lattice, a supporting member is connected between the middle point of the connecting member and the intersection of the lower chord member,
The joint at the intersection of the lower chords is complicated. Therefore, this invention was devised to avoid the concentration of members by connecting the lower end of the support member between the midpoints of the lower chord, and to also prevent the lower chord from buckling. The details will be explained below with reference to illustrated embodiments.

点間に支持材６を連結してある。 The unit frame member 1 is configured to form a truss shape by connecting an upper chord member 2 and a lower chord member 3 with a lattice member 4,
This unit frame material 1 is configured to form a large number of quadrilateral lattices. The connecting member 5 is arranged to connect the intermediate points of the upper chord members 2, 2 of the adjacent frame members 1, 1. The connecting members 5 can be connected to adjacent grids. In order to reinforce the tie member 5, a support member 6 is connected between the middle point of the tie member 5 and the middle point of the lower chord member 3.

の繋材は母屋受けを兼用することもできる。 This device has the above-mentioned configuration, in which a tie member is arranged and connected between the upper chord members on the compression side of the space truss, and a support member is arranged and connected between the middle point of the tie member and the middle point of the lower chord member. Therefore, the buckling length of the frame material, especially the top chord material and the bottom chord material, is shortened, the length of the frame material forming the rectangular lattice can be made longer than that of the conventional one, and the concentration of components at the bottom chord joint is reduced. few. Therefore, it is possible to increase the size of the square grid, which in turn reduces the number of joints on site, reduces the number of times frame materials are lifted, and improves construction efficiency. Furthermore, since a triangular lattice is formed in a part of the square lattice, the rigidity and stability of the entire three-dimensional truss can be improved, and furthermore, this connecting member can also be used as a purlin support.
