Disclosed is a rigidity-flexibility combined type tensile seismic isolation device. A seismic isolation support is disposed in a cavity of an upper support fixing body, an upper connecting plate of the seismic isolation support is in rigid connection with the upper end of the upper support fixing body, a lower connecting plate of the seismic isolation support is in rigid connection with the upper end of a lower support fixing body positioned in the cavity of the upper support fixing body, the upper end of the lower support fixing body is supported by the lower end of the upper support fixing body by means of contacting to enable the lower support fixing body to be in a suspended state, the lower end of the lower support fixing body extends into an inner cavity of a lower buttress connector, and a precompressed elastomer is arranged in a cavity formed by the lower end of the lower support fixing body and the upper end of the lower buttress connector. The rigidity-flexibility combined type tensile seismic isolation device has the advantages that when the rigidity-flexibility combined type tensile seismic isolation device bears pressure, the upper support fixing body and the lower support fixing body move vertically oppositely without affecting vertical compression performance of the seismic isolation support; when under the action of vertical tensile force, the lower end of the upper support fixing body and the upper end of the lower support fixing body extrude mutually, so that opposite vertical displacement can be avoided to guarantee that the seismic isolation support is not in the tensile state.
