Industrially assembled multiple high-rise steel special-shaped column frame-eccentric supporting system

Abstract

The invention provides an industrially assembled multiple high-rise steel special-shaped column frame-eccentric supporting system, and relates to the technical field of structural engineering. The industrially assembled multiple high-rise steel special-shaped column frame-eccentric supporting system comprises assembled truss plates, assembled special-shaped columns and eccentric supporting components, wherein the assembled truss plates comprise structural truss beams and floor slabs, and the structural truss beams are provided with channel steel web members; the assembled truss plates are prefabricated in a factory, the assembled truss plates are mutually spliced with flange plates of the assembled special-shaped columns through beam-end blanking plates of the assembled truss plates at the construction site, and the assembled special-shaped columns are spliced on site through bolts in an interlayer to form a multi-layer truss plate steel frame structure; on the basis of the steel frame structure, the eccentric supporting components are connected to the truss beams in a beam plate layer of the frame structure or the bottoms of the columns to serve as lateral load resistance components; the assembled truss plates, the assembled special-shaped columns and the eccentric supporting components are all fabricated in the factory and assembled through the bolts on the construction site.

Description

technical field [0001] The invention relates to an industrially assembled multi-story steel special-shaped column frame-eccentric support system, which belongs to the technical field of structural engineering. Background technique [0002] my country's annual urban and rural housing area is 2 billion square meters, of which more than 80% are high-energy buildings, and the energy consumption per unit building area in my country is more than twice that of developed countries. According to the statistics of the China Iron and Steel Association, in 2011, my country's steel output exceeded 700 million tons, ranking first in the world's steel output for 16 consecutive years. Our country is less than 4%. As the country with the largest construction scale and steel output in the world, China lags behind seriously in the development of steel structures for houses (including residences). [0003] At present, the systematic research on high-rise steel structure residences at home and ...

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.

[0004] In the traditional steel frame structure system, the lateral rigidity of the structure is difficult to meet the requirements, and the deformation is large, which is easy to cause damage to non-structural components. The industrially assembled multi-story steel special-shaped column frame-eccentric support system adds an additional Lateral and longitudinal eccentric supports increase the lateral stiffness of the structure and improve the deformation performance of the structure
