Assembly type beam-column node connection device with function recovery effect

Abstract

The invention relates to an assembly type beam-column node connection device with a function recovery effect, and belongs to the field of structure engineering. The assembly type beam-column node connection device with the function recovery effect consists of a round steel pipe column with a cantilever beam section, a general beam section and a connection device for the round steel pipe column and the general beam section. According to the node connection device, welded parts are all finished in a factory, so that the weld seam quality and the machining precision can be more easily controlled; the round steel pipe column with the cantilever beam section and the general beam section are assembled by adopting a high-strength bolt and a connection plate on site, so that the construction speed is greatly increased and the construction quality is greatly improved; meanwhile, the general beam section can be arranged on the connection plate at the lower part of the cantilever beam section, so that the difficulty in construction is lowered and the field assembly and positioning are easy; a node is used for both beam end reinforcement and cover plate connection weakening; through reasonable parameter design, double energy consumption of frictional sliding of the bolt and plastic deformation of the connection plate and the bolt can be realized and a plastic hinge can be transferred to the connection plate; and the function of the structure can be recovered only by replacing the connection plate after earthquake.

Description

technical field [0001] The invention relates to an assembled beam-column joint connection device with recoverable functions, 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 ...

Once the existing multi-story public buildings and residential buildings are damaged by an earthquake, the buildings will be terminated, which will have a serious impact on social economic recovery and people's lives. At the same time, the economic losses caused by the closure of some buildings after the earthquake may exceed the structural its own economic value
