Description
Technical Field
[0001] The utility model relates to the technical field of steel structures, in particular to a welding fixing device for building steel structures. Background Technique
[0002] Building steel structures refer to structural forms that can bear and transfer loads, which are connected by steel plates and hot-rolled, cold-bent or welded profiles through connectors. They are mainly composed of beam steels, steel columns, steel trusses or steel pipes made of section steels and steel plates, etc. Steel structure parts are widely used in high-rise buildings, industrial factories, bridges, stadiums, convention centers and other fields.
[0003] In view of the above and existing related technologies, the inventor believes that the following defects often exist: Steel pipes are common steel structure parts. When steel structure parts are needed, most of them need to connect two or more steel structure parts together. The common connection method is to complete the connection by welding. Since most welding operations lack special fixing mechanisms, workers need to manually complete the position limitation and alignment of steel structure parts during welding, which is prone to difficult operation problems during operation. Therefore, a welding fixing device for building steel structures is proposed for the above problems. Content of the Utility Model
[0004] In order to make up for the deficiencies of the prior art and solve at least one of the technical problems proposed in the background technique.

The surfaces of the two backing plates are both provided with a limiting device. The limiting device includes a moving block. The surface of the moving block is slidably connected to the inner wall of the backing plate. A placing block is fixedly connected to the upper surface of the moving block. A threaded rod is rotatably connected to the inner surface of the placing block. Two opposite threads are provided on the surface of the threaded rod. Two clamping rings are threadedly connected to the surface of the threaded rod. Push the moving block to make the moving block slide on the inner surface of the backing plate. The moving block drives the placing block, the threaded rod, the clamping rings and the steel structure pipe to move. After the two steel structure pipes are fitted together, welding is carried out. By setting the moving block, the placing block, the threaded rod and the clamping rings, the position of the steel structure pipe can be fixed, and at the same time, it is convenient to adjust the position of the steel structure pipe.

When the rotating plate rotates, it rotates at the bottom end of the limiting plate, and the limiting plate can limit the position of the rotating plate.
[0012] The beneficial effects of the present utility model are as follows:
[0013] 1. When welding the steel structure pipe is required in the present utility model, the moving block is pushed to slide on the inner surface of the backing plate.
