[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. When welding steel structures, a clamping bracket structure for steel structure welding is required to fix it.

[0003] According to the description of a positioning bracket for steel structure welding disclosed on the patent website (authorization announcement number: CN216503205U), "The utility model relates to the technical field of steel structure welding, and in particular to a positioning bracket for steel structure welding. Its technical solution includes: a base plate and a movable plate, threaded rods are rotatably installed in the middle of both sides of the upper surface of the base plate, and rotating shafts are embedded and installed in the middle of both sides of the upper surface of the base plate. The bottom ends of the threaded rods rotate relative to the base plate through the rotating shafts, and the bottoms of the two threaded rods are respectively provided with turntables, and the two threaded rods pass through the middle of both sides of the movable plate respectively. The movable plate is located above the base plate, and a support plate is installed in the middle of the upper surface of the movable plate. Connecting columns are fixed at the four corners of the lower surface of the support plate, and four connecting holes matching the connecting columns are provided in a rectangular array in the middle of the upper surface of the movable plate. The connecting columns are inserted into the connecting holes, and the lower surface of the support plate contacts the upper surface of the movable plate. A positioning groove is provided in the middle of the upper surface of the support plate. The utility model has the advantages of stably adjusting the height of the steel structure and facilitating welding."

[0004] In view of the above description, the applicant believes that there are the following problems:

However, in actual use, when fixing steel structures of different sizes, it is necessary to frequently install different support plates on the shifting plate through plug-in columns, which is time-consuming. Secondly, when the rotating turntable drives the threaded rod to rotate, the two turntables need to be rotated at the same speed at the same time. During operation, there is a large possibility of error, which can easily cause serious damage to the threaded rod and the shifting plate installation, reducing the service life. Therefore, it is necessary to improve a clamping bracket structure for steel structure welding to solve the above problems. Utility Model Content
