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.

Embodiment Construction

[0056] The present invention is described in detail below in conjunction with accompanying drawing:

[0057] as attached figure 1 As shown, the splicing position of the assembled truss plate of the present invention is set in the middle of the main girder, where the shear force and bending moment are relatively small. From the perspective of structural mechanics, the setting of the splicing position is reasonable.

[0058] as attached figure 2 As shown, in the hollow special-shaped column multi-story assembled steel structure system of the present invention, the beam involved is a truss beam composed of channel steel and gusset plate splicing, including upper and lower chords II5, web members 2 and gusset plates 3 , where the upper and lower chords I5 and web 2 are respectively made of channel steel and angle steel, and are divided into single-channel steel beams and double-channel steel beams according to the upper and lower chords, and the single-channel steel beams are pr...

Abstract

A hollow irregular column multi-layer high-rise assembling steel structure system relates to the technical field of engineering and comprises assembling truss plates and assembling flange columns. 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. The assembling truss plates and the assembling flange columns are all prefabricated in the factory and assembled through bolts on the construction site.

Description

technical field [0001] The invention relates to a multi-story assembled steel structure system of hollow special-shaped columns, 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 "Hollow Twelfth Five-Year Plan" has brought the construction industry ...
