Viscous damping spherical steel support
The invention discloses a viscous damping spherical steel support which comprises an upper support plate, the upper support plate is located above a middle support plate, a lower support plate is located below the middle support plate, a cambered surface groove is formed above the middle support plate, a spherical crown lining plate is arranged in the cambered surface groove, and a sliding groove is formed in the upper end of the lower support plate. A guide plate is fixedly installed at the lower end of the middle seat plate through bolts and slidably loaded in a sliding groove, guide sliding plates are fixedly arranged on the two walls of the sliding groove, dampers are loaded at the left end and the right end of the lower support plate in the transverse bridge direction respectively, clamping grooves are loaded at the left end and the right end of the lower support plate respectively, and middle cylinder bodies of the dampers are located between the clamping grooves. The anti-shearing performance is reliable; a viscous damping device is arranged, so that the requirements for slow sliding under daily working conditions and rapid movement and damping energy dissipation under earthquake working conditions are met at the same time; a safety pin structure is further arranged, a safety pin can be cut off in time under the earthquake fortification effect, a bridge consumes energy through the dampers on the two sides, and the shock absorption effect is achieved.
本发明公开了一种粘滞阻尼球型钢支座，包括上支座板，所述上支座板位于中间座板上方，下支座板位于中间座板下方，中间座板上方设有弧面槽，弧面槽内部装设有球冠衬板，下支座板上端开设有滑槽，中间座板下端通过螺栓固定安装有导向板，导向板滑动装载在滑槽内，滑槽两壁上固定设置有导向滑板，所述下支座板横桥向左右两端分别搭载有阻尼器，下支座板左右两端分别搭载有卡槽，阻尼器中缸体位于卡槽之间；本发明抗剪性能可靠；且设置粘滞阻尼装置，同时满足日常工况下慢速滑移与地震工况下快速运动与阻尼耗能作用；本发明还设置保险销结构，在设防地震作用下时保险销能够及时剪断，使得桥梁通过两侧阻尼器耗能，达到减震效果。
