Problems solved by technology

[0004] At present, the existing prefabricated corrugated web beam-column joints and bolted-welded beam-column joints have roughly the same failure mode, that is, the overall damage in the area will occur, and the function cannot be quickly restored after the earthquake, which makes the prefabricated steel structure building The post-earthquake repair and reinforcement are no different from traditional steel structure buildings, and it is impossible to achieve "prefabricated buildings that can quickly restore functions".

Abstract

The invention relates to a fabricated corrugated web beam-column joint connecting device with a restoration function, and belongs to the field of structural engineering. The fabricated corrugated web beam-column joint connecting device with the restoration function is composed of a round steel tubular column provided with a cantilever beam section, a corrugated web I-shaped beam section and a connecting unit for the round steel tubular column provided with the cantilever beam section, and the corrugated web I-shaped beam section. The welding work of the joint connecting device is finished in a factory, the weld quality and machining precision are easier to control, high-strength bolts, connecting plates and L-shaped connecting pieces are adopted on site to fabricate the round steel tubular column provided with the cantilever beam section, and the corrugated web I-shaped beam section, the construction speed is greatly increased, and the construction quality is greatly improved; and meanwhile, the corrugated web I-shaped beam section can be overlapped on the connecting plate on the lower portion of the cantilever beam section, the construction difficulty is lowered, and on-site splicing and positioning are facilitated. A joint of the fabricated corrugated web beam-column joint connecting device with the restoration function is a beam-end reinforced joint; and through reasonable parameter design, double energy consumption of bolt friction gliding and plastic deformation of the connecting plates and the bolts can be achieved, and post-earthquake fast restoration can also be achieved.

Description

technical field [0001] The invention relates to a recoverable assembled corrugated web beam-column node connection device, which belongs to the technical field of structural engineering. Background technique [0002] Since the reform and opening up, my country has achieved world-renowned achievements in the field of urban construction. At the same time, the traditional extensive construction mode with high energy consumption, high pollution, and low efficiency is still relatively common, which is incompatible with the development requirements of new urbanization, industrialization, and informatization. far cry. Changing the production mode of the existing construction industry and developing green buildings is an important strategy to lead the new normal of economic development and achieve sustainable development. The prefabricated steel structure building has the characteristics of standardized design, factory production, assembly construction, integrated decoration, and in...
