る。According to the non-welded truss, the entire assembly can be performed only by the bolting operation using the one-side bolt 8, and the joining can be easily performed without requiring any special positioning. That is, it is possible to join with high accuracy only by managing the bolt holes 11 and 12. Therefore, the assembling time of the truss 1 is greatly reduced. In addition, assembling can be performed easily and accurately in this manner, and a positioning jig is not required.
The truss 1 can be assembled on site and transported in a wire state to reduce the transport volume. Instead of the one-side bolt 8, a normal bolt / nut may be used. However, by using the one-side bolt 8, the nut can be held at the time of bolting work, or the back nut can be used in advance. Work such as welding is unnecessary, and the truss assembling work by bolting work can be further speeded up.

Nothing. Therefore, a bolt head or the like does not hinder a member arranged adjacent to the truss. further,
Although the plates 6 and 7 are used for joining the chords 2 and 3 to each other, most of the lattice members 4 and the bundle 5 are directly joined to the chords 2 and 3. Plates are reduced, and the number of mounting bolts on the plate is reduced.
