建築物の揺れを低減することができる。According to a fifth aspect of the present invention, there is provided a mounting structure for a seismic isolation device, wherein the seismic isolation device extends in a direction perpendicular to the lower rail, the lower rail being connected to the base structure, and the upper structure. Consists of an upper rail to be connected and a center block that displaceably engages the lower rail at the lower part, displaceably engages the upper rail at the upper part, and supports the upper structure from the base structure. The lower rail or upper rail is connected to the base structure or upper structure via a soft plate or elastic body, so construction errors, building,
The soft plate is deformed or the cushioning material operates in response to the dimensional error and eccentricity of the seismic isolation device, and the load during the seismic isolation operation. This is performed without incorporating a movable mechanism. In addition, the height of the center block of the seismic isolation device can be made smaller than that of a conventional seismic isolation device with a built-in mechanical movable mechanism. Lower,
The shaking of the building can be reduced.
