Buffering anti-beam-falling bridge support
The invention provides a buffering anti-beam-falling bridge support which comprises a base plate, a middle connecting base plate, a horizontal shearing buffering mechanism and an upper base plate, and the middle connecting base plate can be horizontally installed on the base plate in a sliding mode; the horizontal shearing buffering mechanism is arranged in a surrounding mode in the circumferential direction of the base plate and abuts against the middle connecting base plate. The upper seat plate can slide in the longitudinal bridge direction and the transverse bridge direction and is rotatably installed on the middle connecting seat plate around the central axis of the middle connecting seat plate. When the upper seat plate moves beyond a first preset distance range in the longitudinal bridge direction under the action of a beam body or moves beyond a second preset distance range in the transverse bridge direction, the horizontal shearing buffer mechanism is extruded through the middle connecting seat plate; the horizontal shear buffering mechanism generates horizontal shear resistance to buffer movement of the beam body. According to the scheme, the buffering anti-beam-falling bridge support can be integrally coordinated in the longitudinal bridge direction and the transverse bridge direction to buffer the earthquake acting force, effective damping in all directions is achieved, and the better anti-beam-falling effect is achieved.
本发明提供了一种缓冲防落梁桥梁支座，包括底座板、中间连接座板、水平剪切缓冲机构和上座板，中间连接座板可水平滑动地安装在底座板上；水平剪切缓冲机构沿底座板的周向环绕设置并与中间连接座板相互抵接；上座板沿纵桥向和横桥向可滑动且绕中间连接座板的中轴线可旋转地安装在中间连接座板上；上座板在梁体作用下沿纵桥向移动超过第一预设距离范围或沿横桥向移动超过第二预设距离范围时通过中间连接座板挤压水平剪切缓冲机构；水平剪切缓冲机构产生水平剪切阻力以缓冲梁体的移动。本方案的缓冲防落梁桥梁支座能够在纵桥向和横桥向整体协调以缓冲地震作用力，实现各个方向的有效减震，具有更加良好防落梁效果。
