Longitudinal elastic constraint multifunctional seismic mitigation and isolation support
The invention discloses a longitudinal elastic constraint multifunctional seismic mitigation and isolation support. The support comprises a lower seat plate; a middle seat plate which is in sliding connection with the lower seat plate and is provided with a first cambered surface; a rotating piece which is located on the middle seat plate and provided with a second cambered surface, wherein the second cambered surface makes contact with the first cambered surface; a first limiting device which is installed on the rotating part and abuts against the middle seat plate to limit the first cambered surface to slide relative to the second cambered surface, wherein the connecting strength of the first limiting device and the rotating part is smaller than a preset threshold value; second limiting devices which are installed on the lower seat plate and located on the two sides of the middle seat plate in the longitudinal bridge direction respectively to limit the sliding distance of the middle seat plate in the longitudinal bridge direction; and a restraining device which comprises a connecting assembly and an elastic piece, wherein the connecting assembly is connected with the lower seat plate and the elastic piece. The support has the longitudinal adjustable limiting function and longitudinal elastic constraint, the anti-seismic property is improved, a telescopic adjuster can be omitted for a large-span bridge, the maintenance workload is reduced, and the construction cost and the operation cost can be saved.
本发明公开了一种纵向弹性约束多功能减隔震支座，支座包括：下座板；中座板，与下座板滑动连接，具有第一弧面；转动件，位于中座板上，具有第二弧面，第二弧面与第一弧面接触；第一限位装置安装在转动件上，并与中座板抵接，限制第一弧面相对第二弧面滑动，第一限位装置和转动件的连接强度小于预设阈值；第二限位装置安装在下座板上，分别位于中座板沿纵桥向方向的两侧，限制中座板沿纵桥向方向的滑动距离；以及约束装置，包括连接组件和弹性件，连接组件连接下座板和弹性件。支座具备纵向可调限位功能、纵向弹性约束，并提高了抗震性能，可以实现大跨度桥梁取消设置伸缩调节器，减少养护维修工作量，有利于节约建设成本及运营成本。
