Problems solved by technology

The disadvantages of this kind of bolted ball grid structure are: complex processing technology and long processing time; a large number of scaffolds need to be erected during installation, which is inconvenient for construction; and it is heavy, consumes materials, and costs high
The disadvantages of this welded ball grid structure are: on-site assembly is required; and the assembly time is long; the welding quality is high; the overall structure has low safety and reliability coefficient and high risk
[0006] Therefore, the traditional above-mentioned two kinds of grid balls have their own different shortcomings, and there are problems such as time, safety, and cost of grid construction.

Description

field of invention [0001] The invention relates to a building grid structure, in particular to a grid ball connection structure and a manufacturing method thereof. Background technique [0002] The building grid structure is a large-span, large-area, and large-space building roof structure. It is especially suitable for large industrial plants, large sports buildings, public buildings, and airport buildings. In recent years, the application of grid structure has also been extended to decorative grids. The grid structure is a metal grid structure composed of grid rods and grid balls. The grid ball is an important part of the grid structure. [0003] Grid ball structure, it can generally be divided into bolted ball grid structure and welded ball grid structure. [0004] Bolt balls are solid steel balls with built-in threads. The bolt ball grid structure is to connect the grid rods with the bolt ball sphere through high-strength bolts. The disadvantages of this kind of bol...
