An industrialized modular multi-high-rise fabricated steel frame system

Abstract

The invention relates to an industrialized modularized high-rise assembled steel structure framework system, which belongs to the technical field of the structure engineering. The industrialized modularized high-rise assembled steel structure framework system is formed by assembling assembled-type floor slabs and assembled-type flange columns by adopting bolts; each assembled-type floor slab comprises a plate A, a plate B and a plate C, and every two adjacent assembled-type floor slabs are spliced by adopting the bolts to form an entire floor slab of a building. By integrating the modularization, factorization and assemblization, the factorized production of the steel structure system is realized, rapidness in on-site assembling can be realized, the construction speed can be increased, the construction period can be shortened, and the engineering cost can be reduced; the high-strength bolts are used for assembling the system on site, so that the environmental pollution caused by the concrete pouring and steel material welding can be avoided; the structural components can be high-efficiently recycled after being disassembled, so that the construction garbage can be reduced, an environment-friendly concept can be actually realized, and the industrialized modularized high-rise assembled steel structure framework system is a green structural system.

Description

technical field [0001] The invention relates to an industrialized modular multi-high-rise assembled steel structure frame system, which belongs to the technical field of structural engineering. Background technique [0002] According to the statistics of China Iron and Steel Association, in 2011, my country's steel output exceeded 700 million tons, ranking first in the world's steel output. The steel structure building area in the United States accounted for more than 50% of the total building area, and Japan accounted for 80%, while my country accounted for less than 40%. %. China, as a big steel production country in the world, lags far behind in the development of steel structure housing. [0003] my country's "Twelfth Five-Year Plan" proposes to bring the construction industry into the era of energy conservation, emission reduction and green environmental protection. The "Green Building Evaluation Standards" issued by the Ministry of Housing and Urban-Rural Development d...

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.

[0005] At present, the problem of the existing multi-high-rise fabricated steel structure system in my country is that the splicing position of the floor slab is located at the joint of the beam-column connection, and the rigid connection of the joint cannot be realized only by relying on a limited number of high-strength bolts, which is not conducive to the stress of the structure
