Prefabricated swing pier structure system of self-resetting viscous damper
The invention relates to a prefabricated assembly type swing pier structure system of a self-resetting viscous damper, and belongs to the technical field of bridge engineering seismic mitigation and isolation. Comprising a prefabricated pier column, a prefabricated bearing platform, a prefabricated adding platform, a limiting steel plate, a viscous damper and a friction plate. A friction plate is arranged between the prefabricated adding table and the prefabricated bearing table, the limiting steel plate is arranged along the prefabricated adding table in a sleeved mode, and the viscous damper is arranged between the limiting steel plate and the prefabricated adding table and comprises an outer sliding sleeve, a piston rod, a sealing cover A, a magnet A, a piston, a cylinder wall, a sealing cover B, a magnet B, an upper end cover and a lower end cover. In the earthquake process, the whole structural system swings, earthquake energy is dissipated through the self-resetting viscous damper, meanwhile, the bridge structure can return to the original position through the self weight of the structure and magnet repulsive force, and damage to the bridge structure under the earthquake effect is effectively controlled. According to the method, on-site full-prefabricated assembly construction can be achieved, the construction period is effectively shortened, and an efficient, rapid and green industrial building mode is achieved.
本发明涉及一种自复位粘滞阻尼器的预制装配式摇摆桥墩结构体系，属于桥梁工程减隔震技术领域。包括预制墩柱、预制承台、预制加台、限位钢板、粘滞阻尼器以及摩擦片；预制加台和预制承台之间设置有摩擦片，限位钢板沿预制加台一圈套设设置，粘滞阻尼器设置在限位钢板和预制加台之间，包括：外滑套、活塞杆、密封盖A、磁铁A、活塞、缸壁、密封盖B、磁铁B、上端盖、下端盖。地震过程中，整个结构体系产生摇摆，通过自复位粘滞阻尼器耗散地震能量，同时通过结构自重及磁铁斥力，可使桥梁结构回复至原始位置，有效控制桥梁结构在地震作用下的损伤；本发明可实现现场全预制拼装施工，有效缩短施工工期，实现高效、快捷、绿色的工业化建造方式。
