specific Embodiment approach
[0031] The present invention aims to provide a ring-shaped friction rotating shock-isolation bearing, which provides ring-shaped friction through rotation deformation, and sets a frequency conversion shock-isolation system and a buffer spring to improve the deformation capacity of the shock-isolation mount and realize the next direction of extremely large earthquakes and long-period earthquakes. Seismic performance goals of the limit. The specific implementation is as follows:
[0032] Such as figure 1 As shown in the figure, a ring-shaped friction-rotation shock-isolation device that can be used for shock absorption of buildings and bridges is composed of an upper cover plate 1, a rotating rigid body 2 in bite contact with the upper cover plate 1, and an annular friction wall in contact with the lateral curved surface of the rotating rigid body 2 3. The buffer spring 4 connected to the lower part of the rotating rigid body 2, the lower part of the buffer spring 4 is connecte...
