Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a technical field relating to a seismic isolation device in which a seismic isolation member is interposed between an upper mount and a lower mount.

[0002]

2. Description of the Related Art As a conventional seismic isolation device, for example, the seismic isolation device disclosed in Japanese Patent Laid-Open No. 11-287291 is known. This conventional seismic isolation device is of a laminated type in which a seismic isolation member is interposed between an upper pedestal and a lower pedestal, and is provided with a side plate that covers the side surface of the seismic isolation member and has a good appearance. I am making it.

[0003]

However, in the above-described conventional seismic isolation device, one end of the side plate is fixed to the edge of the upper mount or the lower mount by a hinge with a coil spring, and the other end is attached and detached by a catch member. It is fixed by adsorption. Therefore, the side plate that is opened by the stress applied to the upper or lower base during seismic isolation operation is subjected to the vertical force (vertical direction) with respect to the seismic isolation device due to the elastic bias of the coil springs and the stress applied to the upper or lower base. Since the side plate moves up in the (direction) direction, there is a problem that the seismic isolation operation imposes a load on the upper or lower pedestal that is moving, and the seismic isolation performance is impaired. The own weight of the attached side plate may affect the seismic isolation operation.

Further, as a form of covering the side surface of the seismic isolation device, there is a form in which a cover member or the like is simply detachably attached to the side surface of the seismic isolation device by a magnet, but the cover member falls off from the seismic isolation device during seismic isolation. Therefore, there is a problem in that the seismic isolation member interferes with the seismic isolation operation. After the seismic isolation operation, there is a problem in that the cover member that has fallen off must be attached and the work for recovering the cover member is required. Further, as a form in which the cover member does not fall off during seismic isolation, a structure in which one end of the cover member is rotatably connected to the side surface of the seismic isolation device by a hinge or the like is used. Since the cover member interferes with the seismic isolation member, the problem that interferes with the seismic isolation operation performed by the seismic isolation member remains unsolved.

The present invention has been made in consideration of such a problem, and it is movable in the horizontal direction with respect to the seismic isolation device and is isolated from the seismic isolation operation of the seismic isolation member to reduce seismic isolation performance. It is an object of the present invention to provide a seismic isolation device and a cover unit that have a good appearance without being damaged.
