Spherical grid steel structure joint

The spherical grid structure is the main structural form of modern grid engineering. Because of the special structure of the spherical grid, the advantages of the grid are better reflected, not only from the cost, but also from the difficulty of construction and the cost of factory processing. The advantages in other aspects are reflected. The advantages of the spherical grid structure are inseparable from the joints of the spherical grid structure. The bolted ball structure of the spherical grid is the essence of the spherical grid, so the spherical grid can become a bolted ball grid.

The joints of the spherical grid structure need to be determined according to the engineering environment, especially the structural modeling of the grid and the analysis of the stress conditions. The spacing of the threaded holes on the bolt ball, the size of the bolt ball, the length of the rod, etc. all determine the spherical net The main factor of the steel structure joint.
