Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model provides a welding bracket for steel structure production as shown in figures 1-5, which comprises a U-shaped bolt 1, an overlapping block 2, a first handle bolt 3, a bracket 4, a second handle bolt 5 and a limiting plate 7, the bottom ends of the two sides of the U-shaped bolt 1 are respectively provided with an external thread 11, the top of the U-shaped bolt 1 is provided with a first threaded hole 12, the limiting plate 7 is connected to the inner side of the U-shaped bolt 1 through an extension spring 6, a slot 71 is arranged on the surface of the limiting plate 7, one end of the second handle bolt 5 is screwed with the first thread opening 12 arranged on the U-shaped bolt 1 until being inserted into the insertion groove 71, specifically, the surface of the limiting plate 7 is sleeved with a rubber pad 8, so that the friction force between the limiting plate and a steel structural section can be increased, the fixing effect is enhanced, meanwhile, the buffer effect is achieved, so that the limiting plate 7 can be tightly attached to sectional materials with various shapes;
