Abstract

A detachable modular beam-column node device, comprising reinforced concrete columns, H-shaped steel beams, node standard parts and connection standard parts. The H-shaped steel beam and the node standard parts are connected by connecting standard parts; the H-shaped steel beam includes H-shaped steel and beam connecting plates, the beam connecting plate has web steel plates, and the node standard parts have L-shaped steel, web steel plates and L The section steel is fixed; several connecting standard parts are divided into two parts, one part is fixed on the beam connecting plate, the other part is fixed on the node standard part, and the two parts are fixed between the connecting standard parts. The connecting device of the present invention connects beams and columns with bolts through standard parts, which saves a lot of on-site wet work and can improve construction efficiency. By connecting beams of different sizes through standard parts of the same size, the standardization of assembled structures is realized and the plasticity of joints is ensured. The hinge area is generated within the range of the device, which can meet the seismic requirements, can be replaced after the earthquake, and effectively increases the energy dissipation capacity of the nodes.

Description

technical field [0001] The invention relates to a detachable modular beam-column node device and a construction method, which belong to the technical field of architecture and structural engineering. Background technique [0002] During the construction process, compared with the traditional reinforced concrete structure, the prefabricated structure is prefabricated and processed in the factory, and the prefabricated components are installed on site, which greatly reduces the original cast-in-place operation. Since each component is prefabricated in the factory, the prefabricated structure can effectively reduce environmental pollution, increase construction efficiency, and meet the requirements of green buildings. Therefore, the prefabricated structure has a very important application prospect. [0003] In the prefabricated structure, the standardization of each component is the development trend of the prefabricated structure. The more standardized the prefabricated struct...
