Steel structure welding and clamping device for building

Abstract

The invention discloses a steel structure welding and clamping device for a building. The device comprises a protection cover and two supporting vertical plates, a driving mechanism and a lifting mechanism are mounted in the protection cover, a supporting plate is mounted on the top of the protection cover, a strip hole is formed in the supporting plate, the two supporting vertical plates penetrate through the strip hole, extend into the protection cover, and are matched with the driving mechanism, the lifting mechanism is mounted above the driving mechanism and is mounted between the two supporting vertical plates, the two ends of the lifting mechanism are mounted on the two supporting vertical plates, a clamping mechanism is mounted on the inner side of each supporting vertical plate, asteel structure can be clamped, welding precision is ensured, under the effect of the driving mechanism, the steel structure can be driven to rotate, a worker can conveniently weld the steel structure, the lifting mechanism can lift the steel structure required to be clamped to the same horizontal plane of the clamping mechanism, the clamping mechanism can conveniently clamp the steel structure, and the work efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of steel structure welding, in particular to a welding clamping device for steel structures used in construction. Background technique [0002] Steel structure is a structure composed of steel materials, which 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 section steel and steel plates. Welding, bolt or rivet connection; because of its light weight and easy construction, it is widely used in large factories, venues, super high-rises and other fields. [0003] When welding the steel structure, it is generally necessary to fix the steel parts. However, artificially aligning and fixing the steel structure will not only have a great impact on the welding accuracy, but also cause instability of the parts and affect the welding. efficiency, and because of the large size of the steel structure, it is neces...

Problems solved by technology

[0003] When welding the steel structure, it is generally necessary to fix the steel parts. However, artificially aligning and fixing the steel structure will not only have a great impact on the welding accuracy, but also cause instability of the parts and affect the welding. efficiency, and because of the large size of the steel structure, it is necessary to use a special bench for clamping and welding operations, and the steel structure must be continuously turned over during the welding process (generally more than 10 times of turning operations are required), and the steel structure is turning over There are potential safety hazards in the process, not only labor-intensive but also relatively low efficiency
