The grid structure is an important branch of the spatial structure system. It constructs an architectural structure form that combines stability and aesthetics through the orderly connection of three-dimensional spatial rods. Currently, commonly used grid forms include bolt-sphere grids and welded-sphere grids. Bolt-sphere grids are assembled and connected through bolt spheres, bolts, sleeves, conical heads, and rods, while welded-sphere grids are welded and connected by hollow spheres and rods. This structural form is widely used in various industrial and civil buildings.
