Abstract

(57) [Summary] [Purpose] To develop a seismic isolation device with a fire-resistant structure that can sufficiently follow large deformations of the seismic isolation device body and properly exhibit its original fire-resistant function. The purpose is to provide. [Structure] A seismic isolation device main body that is inserted between arbitrary structures and can be elastically deformed; If the main body of the seismic isolation device is significantly deformed due to an earthquake or the like, both the base material and the refractory material follow the deformation. That is,
This is because the base material is wrapped around the main body of the seismic isolation device with a sufficient margin, and the fireproof material is made of an easily deformable material. Therefore, its fireproof function is reliably maintained.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a seismic isolation device, and in particular, to a seismic isolation device that can be elastically deformed. Relates to fire-covered structures.

0002

[Conventional technology]

For example, laminated rubber is used as the seismic isolation device. Need this kind of laminated rubber They are placed in suitable locations to provide seismic isolation to various structures. By the way, the above product Layered rubber may need to be fireproofed depending on where it is used. So Conventionally, the laminated rubber was surrounded by a fire-resistant member.

0003

[Problem that the idea aims to solve]

The conventional configuration described above has the following problems. In the case of conventional fireproof construction , if the seismic isolation rubber does not deform or if there is very slight deformation, follow it. It will not be damaged. However, a large earthquake occurred and the laminated rubber was damaged. If the product deforms, it will not be able to follow the deformation and will be damaged. There was a problem. If it is damaged in this way, it will not be able to perform its original fireproof function. There was also the problem that it became impossible to do so.

0004 The present invention was developed based on these points, and its purpose is to It can sufficiently respond to large deformations of the seismic device itself, and maintains its original fireproof function. Our goal is to provide a seismic isolation device with a fire-resistant structure that can function normally. .

[0005]

[Means to solve the problem]

In order to achieve the above object, the seismic isolation device devised in this application can be installed between arbitrary structures. The main body of the seismic isolation device that can be inserted and elastically deformed, and the outer periphery of the main body of the above-mentioned seismic isolation device have a margin. A wrapped base material and an easily deformable fireproof material placed around the outer periphery of the base material. It is characterized by having the following.

[0006]

[Effect]

If the main body of the seismic isolation device is significantly deformed due to an earthquake, etc., the base material and fireproof material should be Together, we will follow the transformation. In other words, the base material should have sufficient margin relative to the main body of the seismic isolation device. The refractory material is made of easily deformable material. Because there is. Therefore, its fireproof function is reliably maintained.

【Example】

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 1 to 6. First, the structure A seismic isolation device main body 5 is inserted between 1 and 3. This seismic isolation device main body 5 includes a pair of The steel plate flanges 7 and 9 and the laminated rubber provided between the flanges 7 and 9 It consists of 11.

[0008] The outer periphery of the seismic isolation device main body 5 is provided with a fireproof structure. That is, as shown in Figure 1. As shown in FIG. It is wrapped. At that time, take into consideration the deformation of the laminated rubber 11, and make sure that it is sufficiently loosened. Wrap it in the same position. In addition to the way of winding the wire 13 shown in FIG. 1, the method shown in FIG. The method shown in FIG. 1 may be used, or another wrapping method may be used. Wai above As shown in FIG. , is fixed at 9.

[0009] Next, as shown in FIG. 5 and FIG. material 17, and ceramic fiber 19 and nonwoven fabric 21 are placed on the outside of the material 17. are arranged sequentially. These rock wool materials 17, ceramic fibers 19, The nonwoven fabric 21 constitutes a fireproof material. The outermost part is also shown in Figure 3. The wire mesh 23 is arranged so as to Then, fix it in several places with fireproof pins 25. It is something to do. The above is the fireproof structure.

0010 According to this embodiment, the following effects can be achieved. First, earthquakes, etc. Even if the laminated rubber 11 deforms significantly, the fireproof structure will not be damaged. It is possible to follow the deformation and maintain its fireproof function. This is Because the rubber layer 13 is wrapped around the laminated rubber 11 in a sufficiently relaxed state, the This is because it can sufficiently follow the deformation of the laminated rubber 11 as shown in FIG. This is because the various components such as rock wool 17 installed are flexible. be. Also, the wire 13 is not fixed to the laminated rubber 11 but to the flanges 7 and 9. Therefore, there is no possibility of damaging the laminated rubber 11.

[0011] Note that the present invention is not limited to the above embodiment. For example, the main body of the seismic isolation device There are various types other than those shown in the figure, and the key is to deform by elastic deformation. It is fine as long as it can absorb the It can also be used as a base material and fireproof material. It can be considered.

0012

[Effect of the idea]

As detailed above, according to the seismic isolation device according to the present invention, the base material is attached to the main body of the seismic isolation device. Is the fireproof material wrapped around the wall with plenty of room and is it made of a material that can be easily deformed? Even if the main body of the seismic isolation device is significantly deformed due to an earthquake, etc., the underlying structure remains intact. materials and refractory materials can reliably follow this and maintain their fireproof function.
