Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fabricated steel structure, in particular to a modular fabricated steel structure connecting structure. BACKGROUND

[0002] Fabricated building is a new type of building method, which is to manufacture uniform prefabricated components in the factory, and then transport them to the construction site for modular installation. Compared with traditional cast-in-place reinforced concrete buildings, it has the characteristics of fast construction speed, less influence of environmental factors, etc., so it is gradually adopted by more real estate developers.

[0003] Fabricated buildings are mainly divided into three technical modes: fabricated prefabricated concrete structure, steel structure and wood structure. Among them, steel structure is a natural fabricated structure. Various beams and columns are mass-produced in the factory, transported to the construction site, inserted into each beam and column, and then welded or fixed with bolts at the connection between the beam and the column. Chinese patent CN202110666055.6 discloses a modular assembled steel structure connecting piece. A connecting column is fixed on each of the four planes of the stand column with a bolt, a slot is formed in the connecting column, and the steel is inserted into the connecting column through the slot and fixed together with the connecting column with a bolt.

[0004] However, each connecting column is only fixed with a side surface of the stand column by a bolt, and the fixing strength is not enough. Moreover, the steel itself is heavy, and once the fabricated building is completed, it is usually used for a long time. Once the bolt fixed between the stand column and the connecting column is damaged, the stand column and the connecting column are separated, which will cause serious safety accidents. If the connection between the stand column and the connecting column is welded, the weld will be gradually corroded by air during long-term use, and the weld will be easily broken, which will also cause serious safety accidents. Moreover, different functional buildings require different layer heights, and the steel structure building made of the modular steel structure has a uniform height, which cannot be assembled into buildings with different layer heights.

[0005] Therefore, a modular fabricated steel structure connecting structure is proposed to solve the above problems. SUMMARY
