[0002] The bolt-ball grid structure is a structural system that uses bolt-ball nodes to spatially connect grid members. It has the characteristics of good integrity, high spatial rigidity, and very stable structure. It can span a larger span with less material. The resulting building structure is light, flexible in space, and beautiful. It is widely used in industrial plants, gymnasiums, exhibition halls, terminal buildings and other buildings.

[0003] Since the grid system is mostly used for large-span structures and has a large number of rods, compared with traditional concrete structures, its manufacturing and installation precision requirements are high and the construction is difficult. The bridge and pipelines of the electromechanical engineering need to be laid in the space between the upper and lower chords of the grid. In addition, the bolt ball spacing is large, and the grid rods cannot bear additional loads and are only allowed to bear force through the bolt ball nodes. Traditional supports and hangers have problems such as lack of fixed points, low rigidity, poor stability, and low construction efficiency. Utility Model Content
