Multi-story/high-rise fabricated steel structural prestressed supporting system capable of realizing rigid connection of joints

Abstract

The invention relates to a multi-story / high-rise fabricated steel structural prestressed supporting system which is capable of realizing rigid connection of joints, and belongs to the technical field of structural engineering. The multi-story / high-rise fabricated steel structural prestressed supporting system is assembled by fabricated floors, fabricated flange columns and fabricated prestressed diagonal supports by bolts; each fabricated floor comprises a board A, a board B and a board C; and the fabricated floors are spliced by bolts to form a whole floor board of a building. Beam-column joints of a steel structural system are connected by welding in a plant, and the prestressed diagonal supports and a frame are also connected by welding in the plant, so that the rigid connection of the joints can be effectively realized, the welding quality can be ensured, and the structure can bear force well. The multi-story / high-rise fabricated steel structural prestressed supporting system has the advantages that the industrial production is realized, the quick fabrication can be carried out in site, the construction speed is enhanced, the construction period is reduced, the construction cost decreases, environmental pollution is alleviated, and dismounted steel can be recycled. The multi-story / high-rise fabricated steel structural prestressed supporting system is environmentally-friendly.

Description

technical field [0001] The invention relates to a multi-high-rise assembled steel structure prestressed support system for realizing rigid connection of nodes, and belongs to the technical field of structural engineering. Background technique [0002] my country's "Twelfth Five-Year Plan" proposes to bring the construction industry into the era of energy conservation, emission reduction and green environmental protection. The "Green Building Evaluation Standards" issued by the Ministry of Housing and Urban-Rural Development defines green buildings as follows: In the whole life cycle, maximize resource saving (land saving, energy saving, water saving, material saving), protect the environment and reduce pollution, provide people with healthy, applicable and efficient use of space, and a building that coexists harmoniously with nature. Steel structure residences can better reflect the essence of green buildings, and the "Twelfth Five-Year Plan" really provides a major opportuni...

Problems solved by technology

[0005] The problem with the existing prestressed support system of multi-story prefabricated steel structures in my country is that the splicing position of the floor slab is located at the node of the beam-column connection, and the lug plate and frame system of the oblique support are spliced ​​with bolts. Realize the rigid connection of nodes, which is not conducive to the stress of the structure
