Description

Technical Field

[0001] The utility model relates to the technical field of steel truss welding, in particular to a welding auxiliary device for connecting steel trusses. Background Art

[0002] A steel truss is a load-bearing frame widely used in buildings and engineering structures, primarily made of steel. It combines triangular or polygonal components to form a lightweight but high-strength structure. Steel trusses have excellent compressive and tensile properties, can effectively disperse loads, and are suitable for large-span spaces such as stadiums, bridges, and industrial plants. To ensure a secure connection between steel truss members and enhance the strength and stability of the overall structure, the individual components are generally connected by welding. Welding can effectively transfer loads and reduce deformation and damage caused by loose connections. Furthermore, the welding process can achieve a high degree of connection accuracy, ensuring coordination between the various components when subjected to stress, thereby increasing the load-bearing capacity and service life of the truss. Generally, a worker places the main truss and support rods in the appropriate position on the workbench and then activates the welding device to weld them.

[0003] However, conventional steel truss welding requires manual placement and positioning of the trusses, increasing the risk of welding defects. This can lead to unstable positions of the main trusses and support rods during welding, slowing down the overall welding process and impacting construction progress. This also increases safety risks and the risk of accidents. To address these issues, those skilled in the art have proposed a welding auxiliary device for steel truss connections.
