Swing type buffer energy consumption type bridge seismic resistance check block structure
The invention belongs to the technical field of bridge seismic resistance, and particularly relates to a swing type buffer energy consumption type bridge seismic resistance check block structure whichcomprises a steel corbel and a check block structure, the steel corbel is fixed to the side face of the top of a pier near a movable support, and the check block structure is fixed to the top of thesteel corbel, and comprises a steel bottom plate, an energy consumption type low-yield-point steel plate, a limiting block, a swing rod and a fixed steel plate. The bridge seismic resistance check block structure can effectively limit large displacement between the beam body and the bridge pier, prevent the beam body from falling in the bridge direction and the transverse bridge direction and being vertically separated from the supports, reduce damage to the movable supports and the expansion joints, meanwhile, the seismic resistance check block structure is arranged near each movable support,collision positions are scattered, the number of collision positions is large, and the earthquake force acting on each stop block structure can be effectively reduced. The check block body comprisesthe energy consumption type low-yield-point steel plate, and part of earthquake energy is consumed through plastic deformation.
本发明属于桥梁抗震技术领域，具体涉及一种摇摆式缓冲耗能型桥梁抗震挡块结构，包括钢牛腿和挡块结构，所述钢牛腿固定在活动支座附近的桥墩顶部的侧面，所述挡块结构固定在钢牛腿顶部，包括钢底板、耗能型低屈服点钢板、限位块、摇摆杆以及固定钢板。本发明桥梁抗震挡块结构能有效限制梁体和桥墩之间的较大位移，防止梁体发生顺桥向和横桥向落梁危害以及梁体竖向脱离支座危害，减小活动支座和伸缩缝的损坏，同时该抗震挡块结构布置在每一活动支座附近，碰撞位置分散，数量多，能有效减小作用在每一挡块结构上的地震力。挡块块体包含一块耗能型低屈服点钢板，通过塑性变形消耗部分地震能量。
