Solid ball sleeve pitch point

Abstract

The invention discloses a solid ball sleeve pitch point. The solid ball sleeve pitch point specifically comprises a multi-screw-hole solid ball, sleeves with inner threads, screw rods with outer threads, and connectors with outer threads. The solid ball is provided with multiple screw holes with the inner threads, the contacting areas of the end surfaces of the screw holes and the sleeves with theinner threads are rubbed flatly, the solid ball can be connected with the screw rods with the outer threads in multiple positions through the inner threads, the screw rod with the outer threads and the connectors with the outer threads can be hollow and can also be solid, the sleeves with the inner threads is connected with the connectors with the outer threads through the threads, and the sleeves sleeves the outside of the screw rod with the outer threads and the connectors with the outer threads. According to the solid ball sleeve pitch point, all kinds of metal materials such as a steel material and an aluminum alloy can be adopted to be applied to all kinds of metal space structures, the pitch point can be manufactured in a factory standardization mode, the sleeves are only needed tobe rotated in field construction to complete rod part connection, field welding is avoided, the operation difficulty is reduced, and the mounting processes of net racks and net shells are more convenient and fast through the pitch point.

Description

technical field [0001] The invention relates to a solid ball sleeve joint, which belongs to the field of building steel structures. Background technique [0002] Spatial grid structure is a curved space structure formed by connecting rod units through nodes. This type of structure has good mechanical performance, high structural stability, and convenient construction. It has been widely used in various industrial and civil buildings. With the development of my country's economic and social levels, the construction industry is facing tremendous pressure from increased labor costs. Improving the level of building assembly can effectively improve production efficiency. However, although my country's spatial grid structure and other systems can achieve standardized production, on-site assembly The time is longer and the cost is higher. [0003] Commonly used nodes in existing spatial grids are welded ball nodes and bolted ball nodes. Solder ball joints cannot realize assembly c...

Problems solved by technology

Welding ball joints cannot realize assembly construction

Although the bolt ball joint can realize assembly construction, problems such as "false tightening" and "difficulty closing the plug rod" often occur during the construction process, which makes the structural system have certain safety hazards
