Self-resetting assembly type subway station flexible antiseismic structure

Abstract

The invention discloses a self-resetting assembly type subway station flexible antiseismic structure, which consists of prefabricated components, prestressed bars, waterproof rubber and rubber support seats, wherein a station main body structure is formed by connecting the prestressed bars and the prefabricated components; the fixed connection of structure connecting nodes can be changed into hinged connection, so that a subway station becomes a flexible system; meanwhile, the structure resetting function can be realized through the prestress; rubber waterproof pads and the rubber support seats are combined into T and TT systems; the systems are arranged at the connection components of the prefabricated components; the multiplex waterproof problems can be solved; the seismic reduction effect can also be achieved. The self-resetting assembly type subway station flexible antiseismic structure has the advantages that the assembly type component connection structure can be solved; the underground station structure can become the flexible system through releasing the bending moment at the connecting parts of the prefabricated components; the deformation capability of the subway station is improved; the antiseismic capability of the underground subway station is improved.

Description

technical field [0001] The invention belongs to the field of anti-seismic technology of assembled subway stations, in particular to a flexible anti-seismic structure of a self-resetting assembled subway station, and further relates to a new type of subway station structure system with self-resetting function and anti-seismic ability assembled by using prestressed tendons to connect prefabricated components. Background technique [0002] With the increasingly prominent contradictions among population, resources, environment and social development space, the development of underground space structure has become an important strategic starting point to solve the contradictions. However, subway stations are severely tested by earthquakes. For a long time, the seismic problems of underground structures have not received enough attention, resulting in the slow development of structural forms, design methods and theories of underground structures. With the intensification of earthq...

Problems solved by technology

In the existing technology, the connection between prefabricated components mostly adopts the "consolidation" connection method of sleeve grouting connection. This connection method makes the structural stiffness change uncoordinated, reduces the seismic capacity of the components, and also affects the structural stability of the components. Waterproof performance, causing corrosion of steel reinforcement, reducing the durability of underground structures
