Hollow irregular column multi-layer high-rise assembling steel frame-central support system

Abstract

A hollow irregular column multi-layer high-rise assembling steel frame-central support system relates to the technical field of structural engineering. The hollow irregular column multi-layer high-rise assembling steel frame-central support system comprises assembling truss plates, assembling flange columns and central support members. Each assembling truss plate comprises a lattice truss beam with an angle steel web member, a column base node and a floor slab. The assembling truss plates are prefabricated in a factory and spliced with one another through beam end sealing plates or the column base nodes on a construction site to form frame structure beam plate layers. The frame structure beam plate layers are connected vertically through the assembling flange columns to form a multi-layer steel frame structure, and the assembling flange columns are arranged on the column base nodes of the assembling truss plates. On the basis of the steel frame structure, the central support members are connected with the bottoms and tops of the truss beams or the columns in the frame structure beam plate layers to be used as lateral load resistance members. The assembling truss plates, the assembling flange columns and the central support members are all prefabricated in the factory and assembled through bolts on the construction site.

Description

technical field [0001] The invention relates to a hollow special-shaped column multi-story assembled steel frame-central 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] The implementation of my country's "Twelfth Five-Year Plan" has brought the construction industry...

AI Technical Summary

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.
