Therefore, some examples are shown below. In other words, the first example is a tension bolt type in which the constituent members are connected to a hemispherical joint hardware using a single high tension bolt arranged in the axial direction, and the second example is a tension bolt type in which the constituent members are connected to a hemispherical joint hardware by inserting the ends of the constituent members into the joint hardware. There are various types such as a welded type in which parts are welded, and a third example is a shear bolt type such as a Waxman joint.

This complicates construction, and with the first tension bolt type, excessive stress is concentrated on the bolt part, requiring high-strength materials, making it difficult to adjust the angle of the component parts, and making it difficult to adjust the angle of the component parts.
The welding type, for example, requires on-site welding work, which requires time and skill, and poses a safety problem because the welding work is performed at a high place.

に溶接により固着している。Reinforcement plates 2 and 2 are installed at six locations on each of the upper and lower sides of the inner peripheral surface of the steel pipe 1.
The reinforcing plates a are vertically opposed and attached by welding, and all the reinforcing plates protrude toward the axis of the steel pipe 1, which coincides with the center of the node P. This reinforcing plate prevents a decrease in rigidity due to out-of-plane deformation of the steel pipe 1. Six beam end support plates 3, 3a are protruded from both upper and lower sides of the outer peripheral surface of the steel pipe 1, respectively, and correspond to the upper and lower reinforcing plates 2.degree. 2a with the tube wall in between. Ring-shaped connecting plates 4, 4ah< are attached to both upper and lower end surfaces of the steel pipe 1, and these connecting plates are fixed to reinforcing plates 2, 2a and supporting plates 3, 3a by welding.

The wear b is connected to the upper and lower support plates 3゜3a through the joint plates 6 and 6 with bolts 7, and similarly, the flange of the chord material is connected to the top plate 8 of the support plate and the bolt 10 through the joint plates 9 and 9. are connected by.

Among the lattice bars 5C in the lattice beam 5, the upper end portion of the lattice bar 501 located at the beam end is connected to the upper support plate 3 with a bolt. In this way, the upper end of the lattice bar 5cl at the beam end is attached to the upper support plate 3 to avoid stress concentration on the bolt part.

型のように高強度の材質を必要としない。(Effects of the Invention) As explained above, according to the present invention, the present device can be constructed without using specially processed members and the construction is simple. It can be constructed using conventional construction techniques, eliminating the need for special construction techniques, simplifying construction, and connecting the steel pipe and the end of the lattice beam by bolts rather than welding, so the angle of the lattice beam can be adjusted. Adjustment is easy, work safety is ensured, and one end of the lattice bar at the end of the beam is concentrated on one side of the steel pipe, preventing excessive stress concentration from occurring at the bolt joint on the negative side. Unlike conventional tension bolt types, high-strength materials are not required.
