Problems solved by technology

This method has the advantage of being extremely flexible, but this method also has disadvantages, which are mainly reflected in the following aspects: 1. When connecting super-large cross-section circular pipes, lug plates are used for butt jointing, and the required number of lug plates cannot guarantee accuracy.
2. Influenced by the weight of the component, the thickness requirements of the lug plate and the welding seam of the lug plate are too high, and they need to be removed after installation, which will affect the aesthetics of the component appearance
3. The end of the component is easily deformed during installation, disassembly and transportation
4. The ear plate affects the welding operation surface and affects the welding quality
Therefore, in the installation and splicing of large components, the technical level of the application personnel is very high, and it is difficult to promote

Abstract

The invention relates to a mounting and splicing joint, in particular to a mounting and splicing joint of a large-section circular steel tube and an operation method of the mounting and splicing joint. The mounting and splicing joint comprises a positive head connecting end and a negative head connecting end, and the positive head connecting end and the negative head connecting end are spliced. According to the mounting and splicing joint of the large-section circular steel tube and the operation method of the mounting and splicing joint, the operation convenience is further improved, and thecomponent safety is improved.

Description

technical field [0001] The invention relates to an installation splicing node, in particular to an installation splicing node of a large-section circular steel pipe and an operation method thereof. Background technique [0002] During the on-site installation and construction of steel structures, the splicing of components is an indispensable link in building construction. The quality of splicing directly affects the quality and safety of construction. The convenience and adjustability of the splicing form also affects the construction period and cost. The traditional splicing joints are connected by lug plates, and after the lug plates are installed and positioned, they are positioned and welded on site. This method has the advantage of being extremely flexible, but this method also has disadvantages, which are mainly reflected in the following aspects: 1. When connecting super-large cross-section circular pipes, lug plates are used for butt jointing, and the required numb...
