[0003] A search of Chinese Patent Publication No. CN221870896U reveals a connector for welding building steel pipes, comprising a mounting plate, an air pump fixedly mounted on the mounting plate, a connecting pipe powered on each side of the air pump, and a middle plate fixedly connected to the connecting pipe; a middle cavity is provided within the middle plate, and eight evenly circumferentially distributed sliding tubes are fixedly connected to the side wall of the middle plate, each sliding tube having a sliding cavity communicating with the middle cavity, and a sliding plate slidably connected within the sliding cavity, with a connecting rod having its other end penetrating the sliding cavity fixedly connected to the sliding plate; the eight connecting rods are divided into four groups, and each group of connecting rods is fixedly connected to a limiting arc plate; through the setting of the limiting arc plate, the limiting arc plate can be moved to closely fit the inner wall of building steel pipes of different diameters, thereby fixing and limiting the building steel pipes of different diameters; through the setting of two symmetrical middle plates, and the limiting arc plate connected by the two middle plates, two building steel pipes of different diameters can be limited and fixed, thus facilitating subsequent welding connection.

[0004] However, in implementing the relevant technology, the following problems were found with the above-mentioned connector for welding steel pipes in building construction: steel pipes with right-angle welding are used in building construction. In the existing technology, it is inconvenient to limit and fix the steel pipes when welding at right angles, resulting in low practicality. Based on this, this utility model designs a connector for welding steel pipes in building construction to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a connector for welding steel pipes in buildings, so as to solve the problem mentioned in the background art of inconvenience in limiting and fixing steel pipes when welding at right angles.

The top of the U-shaped frame is provided with a second corner plate, and the bottom of the second corner plate is fixedly installed with an installation block. The installation block is detachably connected to the first limiting seat and the second limiting seat respectively. The first corner plate and the second corner plate are respectively provided with a fixing component on one side.

[0007] As a preferred embodiment, the fixing assembly includes a support frame, a threaded rod, and a limiting plate. The support frame is located on one side of the first corner plate and the second corner plate, respectively. The threaded rod is installed through the top of the support frame, and the bottom end of the threaded rod is rotatably connected to the top of the limiting plate.

The installation block 7 is inserted into the limiting seat 5, and bolts and nuts are used to secure the installation block 7 to the limiting seat 5. Install between seats 2 and 5. Place the back of U-shaped frame 1 on the ground according to the usage requirements. Place the two steel pipes that need to be welded at right angles on corner plate 1 2 and corner plate 2 6 respectively. Move the two steel pipes to align their ends and limit their movement. Weld the steel pipes at right angles. There are fixing components 8 on one side of corner plate 1 2 and corner plate 2 6 respectively. Place the steel pipes that need to be welded together on corner plate 1 2 and corner plate 2 6 respectively. Move the two steel pipes to align their ends. Rotate the fixing components 8 and move them downward to limit and fix the steel pipes. Then the steel pipes can be welded.
