Modular multi-story prefabricated steel structure prestressed eccentric support system

Abstract

The invention belongs to the technical field of structural engineering, and relates to a modularized multi-story and high-rise assembly type steel structure prestress eccentric supporting system formed by assembling assembly type floors, assembly type flange columns and assembly type prestress sway braces through bolts. Each assembly type floor comprises a board A, a board B and a board C. The assembly type floors are spliced through bolts to form a floor of a whole layer of a building. Beam and column nodes of the steel structure system and connection between the prestress sway braces and a framework are welded in a factory, the rigid connection of the nodes can be achieved effectively, welding quality is ensured, and structural stress is facilitated. The modularized multi-story and high-rise assembly type steel structure prestress eccentric supporting system achieves industrialized production, can be rapidly assembled on site, increases the construction speed, shortens the construction period, lowers building cost of projects and reduces pollution to environment, and steel can be recycled after the supporting system is disassembled, so that the supporting system is an environment-friendly structural system.

Description

technical field [0001] The invention relates to a modular multi-high-rise assembled steel structure prestressed eccentric support system, which 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 opportunity for the innovatio...

Problems solved by technology

[0005] The problem with the existing prestressed eccentric bracing 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. The rigid connection of the nodes cannot be realized, which is not conducive to the stress of the structure
