Multi-directional displacement anti-seismic facility device for bridge
A multi-directional displacement anti-seismic facility device for a bridge comprises an upper pre-embedded steel bar, a middle multi-directional displacement control box and a lower pre-embedded steel bar. The multi-directional displacement control box is of a cuboid cavity structure and comprises a top plate, a bottom plate and side plates which are all formed by welding steel plates. The top plate and the bottom plate are correspondingly provided with sliding long slotted holes which are through up and down, and the bottom end, provided with an external thread, of the upper pre-embedded steel bar extends into the sliding long slotted holes of the top plate and is connected with the top plate through a mounting base plate and a nut; the top end, with external threads, of the lower embedded steel bar extends into the sliding long slotted hole of the bottom plate and is connected with the bottom plate through a mounting base plate and a nut; and the upper pre-embedded steel bar and the lower pre-embedded steel bar are respectively connected with the sliding slotted hole of the middle multi-directional displacement control box in a movable fit manner. Deformation caused by normal temperature change in the longitudinal direction of a bridge does not have the blocking phenomenon, and the requirement for simultaneous large horizontal displacement in the transverse bridge direction and the longitudinal bridge direction of the bridge using the friction pendulum support is met under the action of earthquake loads.
一种桥梁用多向位移抗震设施装置，包括上部预埋钢棒、中间的多向位移控制箱、下部预埋钢棒；多向位移控制箱为长方体空腔结构，包括顶板、底板、侧板均为钢板相互焊接构成；其顶板、底板上对应开设有上下通透的滑动长槽孔，上部预埋钢棒带有外螺纹的底端伸入顶板的滑动长槽孔内，通过安装垫板和螺母连接顶板；下部预埋钢棒带有外螺纹的顶端伸入底板的滑动长槽孔内，通过安装垫板和螺母连接底板；上部预埋钢棒、下部预埋钢棒分别与中间多向位移控制箱的滑动长槽孔移动配合连接。本发明在桥梁纵向正常的温度变化引起的变形不会发生卡死现象，在地震荷载作用下满足桥梁使用摩擦摆支座的横桥向和顺桥向同时大水平位移需求。
