H-shaped steel column framework system of fabricated modularized self-resetting steel structure for multi-storey and high-rise building

Abstract

The invention provides an H-shaped steel column framework system of a fabricated modularized self-resetting steel structure for a multi-storey and high-rise building and belongs to the technical field of structural engineering. The system comprises outer node modules, corner node modules and inner node modules. The invention provides a novel fabricated module. Frame nodes and inflection points are cut out to serve as wholes to be assembled, the bending moment of the frame inflection points is very small, a weak connecting mode can be adopted among columns, the connecting mode is flexible, the steel consuming quantity is reduced, and the connecting difficulty is lowered. Through design of pre-stress steel stranded wires, residual deformation of the frame nodes can be reduced after an earthquake, and the self-resetting effect is achieved. Through arrangement of holding plates, cover plates and outer ribs, while beam accurate positioning can be achieved, stability of the nodes is improved. The outer ribs are arranged in beam flanges, and thus the beautiful effect can be achieved while the local bearing capacity is improved. In production and construction of the steel-structure system, modularization, the factorization, standardization and assemblage are combined, factory production is achieved, and engineering cost is reduced.

Description

technical field [0001] The invention relates to a multi-high-rise assembled modular self-resetting steel structure H-shaped steel column 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 housing steel structures. [0003] The definition of green building: in the whole life cycle of the building, save resources to the greatest exte...

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.
