A multi-high-rise assembled modular self-resetting steel structure square tube column frame system

Abstract

The invention discloses a multi-storey and high-rise fabricated modularized self-resetting steel structure square pipe column framework system and belongs to the technical field of structure engineering. The multi-storey and high-rise fabricated modularized self-resetting steel structure square pipe column framework system comprises outer joint modules, angle joint modules and inner joint modules. The invention provides the novel fabricated modules. Joints and inflection points of a framework are cut out to serve as a whole to be fabricated. The bending moments of the framework inflection points are quite small, columns can be connected weakly, and connecting modes are flexible, so that the steel using amount is decreased, and connecting difficulty is reduced. Through the design of prestressed steel stranded wires, residual deformation of the framework joints after an earthquake can be reduced, and the self-resetting effect is achieved. Supporting plates, cover plates and outer ribs are arranged, so that the stability of the joints is improved while beams are positioned precisely. The outer ribs are arranged inside beam flanges, so that the attractive effect can be further achieved while the local bearing capacity is improved. In production and construction of the steel structure system, modularization, industrialization, standardization and fabrication are combined, industrialization production is achieved, and the engineering construction cost is reduced.

Description

technical field [0001] The invention relates to a multi-high-rise assembled modular self-resetting steel structure square pipe column frame system, which belongs to the technical field of structural engineering. Background technique [0002] In the whole life cycle of the building, save resources to the greatest extent (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 . This concept is an important strategic transformation for changing the mode of economic growth and promoting sustainable development, and it truly provides a major opportunity for the innovation and industrialization of the corresponding system of steel structures for houses (residential buildings) in my country. [0003] At present, the systematic research on high-rise steel structure residences at home and abroad is in its infancy...

Problems solved by technology

A lot of welding is used in the construction of traditional steel structure residential buildings, the construction speed is slow, and the pollution to the environment is serious. The most important thing is that the quality of the welds is not suitable for control, which seriously affects the safety performance of the building.
