Embodiment Construction

[0057] The implementation of the structural system will be described in detail below in conjunction with the accompanying drawings.

[0058] Such as Figure 1~10 As shown, the present invention is an industrially assembled multi-high-rise steel structure prestressed central support system, including a steel structure main frame, a prestressed support member, and a column system, and is characterized in that: the steel structure main frame includes a foundation Frame, column system. Wide beam 3, narrow beam 4 and column base 7 are assembled into foundation plate frame in factory, and floor slab is example with pressed steel plate concrete here, and floor slab can also be forms such as reinforced concrete floor slab. The prestressed support members are described here in a general form. Place the profiled steel plate 5 on the wide beam 3 and the narrow beam 4, connect it with studs, pour concrete 6 on the profiled steel plate 5, use the gaps between the webs of the wide beam 3 ...

Abstract

The invention relates to an industrialized assembled multi-story high-rise steel structure prestressed centrally-braced system, belonging to the field of buildings. The industrialized assembled multi-story high-rise steel structure prestressed centrally-braced system comprises steel structure main body slab racks, prestressed bracing members and columns. Wide beams, narrow beams and column bases are assembled in a factory to form base slab racks. The base slab racks and slabs are integrally fabricated. 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 prestressed 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...
