Technical Field

[0001] The utility model relates to the technical field of welding jigs, in particular to a steel structure welding jig. Background Art

[0002] A steel structure is a structure composed of steel materials and is one of the main building structure types. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of sections and steel plates, and rust removal and anti-rust processes such as silanization, pure manganese phosphating, water washing, drying and galvanizing are adopted. The components or parts are usually connected by welds, bolts or rivets. Because of its light self-weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings and other fields. During the welding process of the steel structure, a jig is needed for fixing;

[0003] The existing patent No. CN220881218U discloses a welding jig for steel structures, including a base and clamping seats slidably connected to both sides of the base. A driving assembly for driving the clamping seats to slide towards each other is connected to the base. An arc groove is connected to the inner side of the clamping seat. A clamping block matched with the arc groove is slidably connected in the arc groove. A rotating assembly for driving the clamping block to slide is connected to the clamping seat. A clamping member for limiting and clamping the steel structure is connected in the clamping block.

For the existing steel structure welding jig, during use, since the length of the steel structure is uncertain and the corresponding length needs to be intercepted according to requirements, when two steel structure building materials are respectively fixed on the corresponding jigs, it is easy that due to the long length of the steel structure parts, one end of the steel structure parts will droop downward during the welding process, and the welding end will tilt upward, thus making it inconvenient to perform welding operations on the two steel structure parts, reducing the applicable range of the jig and being inconvenient to promote;

[0006] 2. The existing steel structure welding jig can only perform clamping and fixing operations on steel structure parts of the same size, which also results that during welding, for steel structure parts of other sizes, jigs corresponding to their sizes need to be selected, increasing the welding cost and being unable to meet the usage requirements.
