Abstract

The invention relates to a function-restorable assembly type beam column-column flange connection joint device and belongs to the field of structural engineering. A function-restorable assembly type beam column-column flange connection joint is composed of a round steel pipe column with a cantilever beam section, a lower round steel pipe column section, a common beam section and a connecting device. Welded parts in the joint device are finished in a factory, and weld seam accuracy and quality are easier to control; the round steel pipe column with the cantilever beam section, the lower round steel pipe column section and the common beam section are assembled only through high-strength bolts and connecting plates on site; fastening work of the bolts is convenient and fast; and construction speed is greatly improved. Meanwhile, the common beam section can be built on the lower connecting plate of the cantilever beam section, so that the construction difficulty is lowered, and on-site assembly and positioning are easy. The joint of the joint device is a beam-end reinforcement and cover plate connecting weakening combined joint; through reasonable design, double energy dissipation of bolt friction slippage and plate plastic deformation can be achieved; fast restoring after an earthquake is easy; and the joint ductility is good, and the energy-dissipating capacity and bearing capacity are high.

Description

technical field [0001] The invention relates to an assembled beam-column-column flange connection node 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 dec...
