Technical Field

[0001] The utility model relates to the technical field of building grids, in particular to a device for connecting bolt ball nodes of building grids. Background Art

[0002] Grid structures can be categorized into flat grids and curved grids based on their appearance. Typically, flat grids are called grids, while curved grids are called grid shells. Grid shells are curved grid structures that combine the characteristics of both rod-based and thin-shell structures. They offer a balanced load-bearing system and a wide span. They are a type of spatial structure that has garnered considerable attention both domestically and internationally, experiencing the fastest growth over the past half century and boasting broad prospects for development.

[0003] During the construction of the building grid, some connection nodes need to connect and fix multiple grid frames through bolt balls, and fixed support rods are installed at the bottom of the bolt balls to support and fix the bolt balls, thereby improving the supporting performance of the building grid. Since the building grid is not flat, the heights of the support rods on the sides of some bolt balls are not symmetrically distributed, and the lengths of the support rods are different. When the support rods on the sides of the existing bolt balls are connected to the grid frame, the angle of the support rods on the sides of the bolt balls cannot be adjusted, resulting in the surfaces of the support rods on the sides of the bolt balls and the grid frame being unable to fit tightly together, thereby affecting the connection and fixation between the support rods on the sides of the bolt balls and the grid frame.

[0004] Therefore, it is necessary to propose a bolt ball node connection device for building grid to solve the above problems. Utility Model Content
