Abstract

The invention provides a detachable modular beam column joint device. The detachable modular beam column joint device comprises a reinforced concrete column, an H-shaped steel beam, joint standard parts and connecting standard parts; the H-shaped steel beam and the joint standard parts are connected through the connecting standard parts; the H-shaped steel beam comprises H-shaped steel and a beam connecting plate; the beam connecting plate is provided with a web steel plate; the joint standard parts are provided with L-shaped steel; the web steel plate and the L-shaped steel are fixed; and a plurality of connecting standard parts are divided into two parts, one part is fixed to the beam connecting plate, the other part is fixed to the joint standard parts, and the two parts of the connecting standard parts are fixed. According to the connecting device, the standard parts and a beam column are in bolt connection, a large amount of field wet operation is omitted, and the construction efficiency can be improved; and the standard parts of the same size are connected with beams of different sizes, standardization of an assembly type structure is achieved, a joint plastic hinge area is generated within the device range, the anti-seismic requirement can be met, replacement can be conducted after an earthquake, and the energy dissipation capability of joints is effectively improved.

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...
