Description

Technical Field

[0001] The utility model relates to the technical field of steel structure welding, in particular to a welding device for assembled steel structures. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. Prefabricated steel structure is a steel structure component that can be assembled on site. Steel structure components usually require welding devices to weld and fix the splicing between steels; Patent No. CN202321490695.7 discloses a welding device for prefabricated steel structure. The technical solution uses the cooperation of L-shaped movable rods and baffles to enable the device to squeeze the baffles through the push plate when in use, thereby pushing the baffles in the direction of the steel, so that the baffles are close to the surface of the steel, and through the staggered L-shaped movable rods and baffles, the surfaces of both sides of the steel are squeezed by the baffles, thereby fixing the steel, making the forces on both sides of the steel balanced, thereby preventing the steel from shaking or dislocating during welding.

[0003] The welding device disclosed above can prevent the steel from shaking or dislocating during the welding process, but its design structure is relatively complicated, which is achieved by staggered L-shaped movable rods and baffles, and there are multiple L-shaped movable rods and baffles, which requires the steel structures to be inserted and connected one by one, resulting in time-consuming actual assembly of the steel structure. In addition, the length of the steel structure is lengthened after welding, which is inconvenient for unloading. For this reason, we design a welding device for assembled steel structures.
