Abstract
The invention provides a novel three-dimensional seismic isolation device which comprises a horizontal seismic isolation component, a transition steel structural platform and a vertical seismic isolation component. The horizontal seismic isolation component is fixedly connected with the vertical seismic isolation component by the transition steel structural platform; and the vertical seismic isolation component comprises an upper sleeve, a lower sleeve, a lower bottom plate, a belleville spring, a middle guide rod and viscous damping fluid. The novel three-dimensional seismic isolation device is simple and convenient to manufacture and is convenient to construct, install and maintain; horizontal damping and vertical damping are decoupled mutually and are not involved mutually. Due to adoption of the belleville steel plate spring, the novel three-dimensional seismic isolation device has low vertical stiffness when vertically moving, so that the vertical period of an upper structure is prolonged and the earthquake action is reduced; and meanwhile, a good viscous hole is formed by a gap between the belleville spring and the lower sleeve for the viscous damping fluid in the lower sleeve and a butterfly steel plate takes an effect of a piston in a viscous damper, so that the vertical earthquake action is further reduced by energy dissipation and safety of the upper structure is ensured.
