Industrialized assembly type special-shaped column steel structure system

Abstract

The invention provides an industrialized assembly type special-shaped column steel structure system and belongs to the technical field of structural engineering. The industrialized assembly type special-shaped column steel structure system comprises assembly type truss plates and assembly type columns. Each assembly type truss plate comprises lattice truss beams and floor slabs and is prefabricated in a factory, and the assembly type truss plates and beam-column joints of the assembly type columns are spliced through beam-end seal plates in a construction site, and the assembly type columns are spliced among layers in the site through bolts to form a multiple-layer truss plate steel frame structure. The assembly type truss plates and the assembly type columns are prefabricated in the factory and are assembled in the construction site through bolts.

Description

technical field [0001] The invention relates to an industrialized assembled special-shaped column steel structure frame 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, my country's steel output exceeded 700 million tons in 2011, 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 into the ...

Problems solved by technology

Traditional steel structure residential buildings use a lot of site welding during construction, 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, and the working environment of the workers is poor, which seriously affects the safety performance of the building.

[0005] Traditional steel structure residential buildings have not fully utilized the advantages of steel structure residential buildings. With the continuous development of my country's steel structure building technology, multi-high-rise steel structure systems should adopt design modularization and component standardization to promote industrialization with standardization and promote industrialization with industrialization. However, domestic research on the modularization of industrialized prefabricated steel structures is still in its infancy, and an innovative modular prefabricated steel structure system is urgently needed
