Technical Field

[0001] The utility model belongs to the technical field of steel structure grid installation, in particular to a ground assembly membrane support frame for a bolt ball node grid. Background Art

[0002] At present, steel structure buildings are widely used in the roof systems of sports, cultural venues, industrial plants and other buildings because of their simple structure, convenient connection, material saving, clear force, high rigidity, good seismic performance, light weight and beautiful appearance. When assembling the prefabricated steel structure grid, it is necessary to connect the grid rods through bolt balls to form the final steel structure grid.

[0003] Since the grid structure is a spatial structure, multiple grid rods need to be connected to the bolt ball at different angles during assembly and connection. Its installation is more complicated than that of a plane structure. It is also troublesome to determine the spatial position of the bolt ball node and the grid rod during ground assembly. In addition, manual support is required when the bolt ball is connected to the rod, which slows down the assembly speed, is inefficient, and the labor consumption cannot be effectively controlled. Therefore, how to improve the assembly efficiency of the bolt ball and the grid rod and reduce labor consumption is an urgent problem to be solved by technical personnel in this field.
