したものである。When a seismic isolation device such as a laminated rubber is installed on a pillar, which is a main structural part such as a pillar, a pillar, a column base, etc. on a general floor of a building, it does not conform to the fireproof building prescribed by the Building Standards Law. . Therefore, the applicant has previously developed various inventions in which the seismic isolation device has a fireproof covering structure. For example, one example is JP-A-3-87443. The present invention has been developed to further improve the performance of the above-mentioned invention, to temporarily support even when the seismic isolation device fails, and to facilitate repair and replacement of the seismic isolation device.

A fire proof panel is arranged by fixing the lower end thereof, and a support base is provided near the seismic isolation device to support a load acting on the seismic isolation device when the seismic isolation device does not function. This is a disaster-prevention structure for a seismic isolation device in which the nozzle of the foam fire extinguisher is arranged around the device facing the outer fireproof panel.

A fire-resistant coating material 3 is provided, which has a slack that bulges outward in the middle and has upper and lower ends secured by bolts. On the side surface of the top of the pillar 1, a fireproof panel 4 having a fireproof performance of about 30 minutes is disposed on the outer periphery of the fireproof covering material by extending upward and fixing the lower end thereof diagonally.

By disposing the fireproof panel to secure the displacement space of the seismic isolation device, the fireproof panel can be moved together with the lower structure, and the flow of the flame against the blowing of the flame creates a flow of wind, deflects the fire outward, and laminates rubber. In addition, it is possible to improve the fire resistance of the fireproof panel by installing a fire extinguishing system, and to improve safety by providing a support base.
