Description

Technical Field

[0001] The utility model relates to the technical field of steel structural parts, in particular to a spliced ​​steel structural part. Background Art

[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. The components or parts are usually connected by welds, bolts or rivets.

[0003] Steel structures have the advantages of high material strength, light weight, steel toughness, good plasticity, uniform material, and high structural reliability. They are widely used in large factories, venues, super high-rise buildings, bridges and other fields. In addition, the demolition of steel structure buildings will hardly generate construction waste, and the steel can be recycled and reused.

[0004] When welding between steel structural parts in existing warehouses, it is necessary to weld the steel sheets to the I-beams by hand, and when welding the steel sheets again on the symmetrical surface of the I-beams, the two sets of steel sheets need to remain level, so the position of the steel sheets needs to be determined multiple times, which is time-consuming and labor-intensive.
