Description

Technical Field

[0001] The invention relates to the technical field of building structure reinforcement, in particular to a reinforced concrete frame structure and a construction method thereof. Background Art

[0002] Reinforced concrete structure refers to a structure made of concrete reinforced with steel bars. The main load-bearing components are made of reinforced concrete. It includes thin shell structures, large formwork cast-in-place structures, and reinforced concrete structures built using slipforms, lifting plates, etc. A structure made of steel bars and concrete. The steel bars bear tension, and the concrete bears compression.

[0003] Referring to the existing Chinese patent with publication number CN115450479A, a reinforced concrete frame structure is disclosed, including a reinforced concrete foundation, a prefabricated reinforced concrete column 1 is attached to the upper end of the reinforced concrete foundation, and a connecting block 1 is fixedly connected to the upper end of the prefabricated reinforced concrete column 1, a connecting block 2 is attached to the connecting block 1, and the connecting block 2 is fixedly connected to the bottom end of the prefabricated reinforced concrete column 2, a prefabricated reinforced concrete beam is attached to the upper end of the prefabricated reinforced concrete column 2, the bottom end of the prefabricated reinforced concrete column 1 is clamped in a connecting piece 1 and fixedly connected by bolts, and the bottom end of the connecting piece 1 is fixedly connected to the reinforced concrete foundation by a positioning screw and a positioning threaded sleeve.

[0004] The above-mentioned reinforced concrete frame structure is provided with a shock absorbing device, which improves the stiffness and ductility of the beam-column joint and significantly improves the seismic performance of the beam-column joint. The present invention realizes the detachability of the structure, and the bolt connection between the prefabricated reinforced concrete components allows the components to be quickly disassembled and assembled, so that any frame components damaged by an earthquake can be replaced in time. However, the above-mentioned reinforced concrete frame structure still has some disadvantages, such as: the bottom end of the connecting piece is fixedly connected to the reinforced concrete foundation by a positioning screw and a positioning threaded sleeve. Under the action of a strong earthquake, the frame structure may produce a large horizontal displacement and deformation, thereby affecting its overall stability, and the node may be damaged due to excessive load. Therefore, we need to propose a reinforced concrete frame structure and a construction method thereof. Summary of the invention

The setting of the elastic sheets can improve the earthquake resistance of the base.
