Novel high-bearing wedge-shaped friction vertical seismic isolation device
The device comprises an upper connecting plate, a supporting column, a cylinder body, a spring steel circular ring and a lower connecting plate, the supporting column is fixedly arranged at the bottom of the upper connecting plate, two or more conical ring grooves are evenly formed in the outer side of the supporting column, the cylinder body is fixedly arranged at the top of the lower connecting plate, the supporting column is inserted into the cylinder body, and the spring steel circular ring is inserted into the cylinder body. More than two square ring grooves are formed in the inner wall of the cylinder body, spring steel rings are connected in the square ring grooves in a sliding manner, and conical bulges matched with the conical ring grooves are fixedly arranged on the inner sides of the spring steel rings. According to the novel high-bearing wedge-shaped friction vertical seismic isolation device, the multiple spring steel rings are placed in the cylinder, each spring steel ring provides axial rigidity and feeds the axial rigidity back to the wedge-shaped stress column in an overlapped mode, and therefore the axial rigidity and the bearing capacity of the device are greatly improved.
本发明公开了一种高承载楔形摩擦的新型竖向隔震装置，包括上连接板、支撑柱、筒体、弹簧钢圆环和下连接板，支撑柱固设于上连接板底部，支撑柱的外侧均匀开设有两个以上的锥形环槽，筒体固设于下连接板顶部，且支撑柱插接于筒体内，筒体内壁开设有两个以上的方形环槽，方形环槽内滑动连接有弹簧钢圆环，弹簧钢圆环内侧固设有与所述锥形环槽配合的锥形凸起。本发明提出的一种高承载楔形摩擦的新型竖向隔震装置，通过在筒体内放置多个弹簧钢圆环，每个弹簧钢圆环分别提供轴向刚度并叠加反馈给楔形受力柱，从而大幅度的提高装置的轴向刚度及承载能力。
