Description

Technical Field

[0001] The utility model relates to the technical field of steel structure processing, in particular to a temporary support fixture for welding delicate steel structure components. Background Art

[0002] In the era of rapid economic development, the advantages of low cost and short construction period of steel structure have attracted more and more attention. Considering the beauty of the building, the steel structure factory will be designed to highlight the difference from other steel structures. The stairs leading to the underground of commercial buildings and residential buildings and the top of the driveway will also use steel structures for the installation of glass and curtain walls. When welding the steel structure, large components can be hoisted by mechanical equipment. At the same time, small components will appear. They have no support points and must be installed and welded by mechanical equipment, resulting in waste of machine hours and greatly increased construction costs.

[0003] In the prior art, temporary support devices are often used when welding and assembling steel structures at high altitudes. However, the existing temporary support devices have a simple structure. When placed on uneven ground, workers are required to adjust their levelness. If the adjustment is wrong, the safety hazard of the entire device when supporting the steel structure will be greatly increased. Therefore, we propose a sophisticated temporary support fixture for welding steel structure components to solve the above problems. Utility Model Content
