Industrialized assembled multi-story high-rise steel structure centrally-braced system

Abstract

The invention relates to an industrialized assembled multi-story high-rise steel structure centrally-braced system, belonging to the field of buildings. The industrialized assembled multi-story high-rise steel structure centrally-braced system comprises steel structure main body slab racks, bracing members and columns. Wide beams, narrow beams and slabs are integrally fabricated in a factory. The wide beams and the narrow beams are welded in the factory by using channel steel. Pipelines pass through positions between the web channel steel of the wide beams and the web channel steel of the narrow beams to form base slat racks A, base slab racks B and base slab racks C. High-strength bolts and partial welding only in the factory are adopted for parts where the base slab racks are connected with column bases and the wide beams are connected with the narrow beams. The column bases are connected with the columns through high-strength bolts and flanges. The industrialized assembled multi-story high-rise steel structure centrally-braced system has the advantages that the construction speed is fast, the structure bearing capacity is high, the lateral movement resistance is good, the strength of materials can be fully exerted, the horizontal load is effectively resisted, the structure interlayer displacement is reduced, the environmental pollution caused by welding is reduced and the cost is saved.

Description

technical field [0001] The invention relates to a novel structural system, in particular to an industrialized assembled steel structure central support system applied in the construction field. Background technique [0002] The construction of ordinary steel structures uses a lot of welding on site, which not only affects the construction speed but also makes it difficult to control the construction quality. In recent years, there have been numerous engineering quality problems caused by the construction quality of steel structures, and on-site welding is one of the most important Factors, on-site welding quality is not easy to control, and it causes great pollution to the environment. [0003] The traditional reinforced concrete structure requires on-site binding of steel bars and pouring of concrete, which requires a lot of labor and maintenance time, and the project cost is greatly increased. And a large amount of construction waste is generated when the building is demo...

[0002] The construction of ordinary steel structures uses a lot of welding on site, which not only affects the construction speed but also makes it difficult to control the construction quality. In recent years, there have been numerous engineering quality problems caused by the construction quality of steel structures, and on-site welding is one of the most important Factors, on-site welding quality is not easy to control, and it causes great pollution to the environment

[0003] The traditional reinforced concrete structure requires on-site binding of steel bars and pouring of concrete, which requires a lot of labor and maintenance time, and the project cost is greatly increased

And when the building is demolished, a large amount of construction waste will be generated.

[0004] In recent years, domestic scholars' research on prefabricated steel structures is limited to multi-layers, and the construction speed is only slightly reduced, and the rapid installation of steel structures has not really been realized, reflecting the advantages of steel structures
