Separation type damping energy consumption three-dimensional seismic isolation support
The invention discloses a separation type damping energy consumption three-dimensional seismic isolation support which comprises a horizontal seismic isolation unit arranged between an upper structure and a middle bearing platform, and a vertical seismic isolation unit arranged between the middle bearing platform and a foundation bearing platform. The horizontal seismic isolation unit is a vertical lead rubber support which is axially and vertically installed, and the vertical seismic isolation unit is formed by connecting at least two inclined lead rubber supports equal in size specification in parallel to form a set of outward expanding cylindrical structure in space symmetry so that the vertical deformation borne by the vertical seismic isolation unit can be transformed into inclined deformation and outward expanding displacement of the inclined rubber supports. An upper friction plate and a lower friction plate are arranged between the vertical seismic isolation unit and the middle bearing platform, and initial supporting force is provided and seism/vibration energy is dissipated through friction sliding of a contact face. According to the separation type damping energy consumption three-dimensional seismic isolation support, seism and environment vibration in three directions can be isolated at the same time, the seism/vibration response and seism/vibration transmission of a protected structure or device with the separation type damping energy consumption three-dimensional seismic isolation support are effectively controlled, and the safety under the seism/vibration action is protected.
