Bridge damping base
The invention relates to a bridge damping base. The problems that an existing bridge support with a horizontal buffering function is complex and loose in structure and poor in stability are effectively solved. According to the technical scheme, the damping device comprises a first damping unit and a second damping unit, and the first damping unit vertically buffers; the second damping unit comprises a vertical cylinder, an annular groove is formed in the inner wall of the cylinder, a sphere-like body embedded in the annular groove is arranged in the cylinder, the sphere-like body and the annular groove form a spherical hinge structure, a buffer layer located below the sphere-like body is arranged in the cylinder, the upper surface of a second elastic buffer layer abuts against the flat bottom of the sphere-like body, and the lower surface of the second elastic buffer layer abuts against the flat bottom of the sphere-like body. A vertical rod is connected to the top of the sphere-like body, and the upper end of the vertical rod horizontally moves along with the bridge body so as to stir the sphere-like body to rotate to extrude the buffer layer for buffering; buffering of displacement in any direction in the horizontal plane can be achieved, the whole support and the internal structure of the support have better stability, and stable supporting and buffering of the support on a bridge under normal vertical load and impact are not affected.
本发明涉及一种桥梁减震底座，有效的解决了现有具有水平缓冲功能的桥梁支座结构复杂松散，稳定性差的问题；解决的技术方案包括第一减震单元和第二减震单元，第一减震单元竖向缓冲；第二减震单元包括竖向的筒体，筒体内壁上开有一个环形槽，筒体内装有一个嵌装于环形槽内的类球体，类球体与环形槽组成一个球铰结构，筒体内设有位于类球体下方缓冲层，第二弹性缓冲层的上表面抵住类球体的平底，类球体顶部连接有一个竖杆，竖杆上端随桥体水平移动从而拨动类球体转动挤压缓冲层进行缓冲；本发明能够实现水平面内任意方位移位的缓冲，整个支座及其内部结构具有更好的稳定性，不影响正常竖向载荷和冲击下支座对桥梁的稳定支撑和缓冲。
