振、免震材に関するものである。[Detailed Description of the Invention] [Field of Industrial Application] This invention provides vibration isolation and seismic isolation materials for buildings that absorb ground vibrations and minimize the vibrations applied to buildings when an earthquake occurs. It is related to.

防振、免震材と、建造物の震動減衰作用をする緩衝材と
から構成されている。-S, seismic isolation devices for buildings are installed between the ground and the building, and include vibration isolation and seismic isolation materials that support the building and absorb seismic waves, and dampen the vibration of the building. It is made up of a cushioning material.
従来のこの免震装置に用いられている防振、免震材は、

震動に対しては震動を吸収する効果があるが、強度の震
動に対して余り効果的ではなかった。The vibration isolation and seismic isolation materials used in this conventional seismic isolation device are:
[Problem to be solved by the invention] However, the vibration isolation of the conventional block-shaped or column-shaped rubber bodies, etc. Seismic isolation materials have relatively high rigidity, so they are effective in absorbing mild vibrations, but they are not very effective against strong vibrations.
また、ゴム体の内部に鋼板が挿入された防振、免震材は
、垂直方向の震動を吸収する効果はあるが、水平方向の
震動を吸収する面で必ずしも満足できるものではなかっ
た。Furthermore, vibration-proofing and base-isolating materials in which steel plates are inserted inside a rubber body have the effect of absorbing vibrations in the vertical direction, but are not necessarily satisfactory in terms of absorbing vibrations in the horizontal direction.
そこで、この発明の目的は、弾性部材と弾性部に埋設さ

軽度の震動を吸収するのみではなく強度の震動にも対応
できる、低い剛性の建造物用防振、免震材を提供するこ
とである。Therefore, an object of the present invention is to create a structure with low rigidity that can not only absorb mild vibrations in the vertical direction but also cope with strong vibrations, by using an elastic member and a reinforcing member having a large number of holes embedded in the elastic part. Our goal is to provide vibration isolation and seismic isolation materials for buildings.

できる。In order to achieve the above object, the present invention provides an elastic member [
3] A large number of holes (5) are formed in the reinforcing member (4) buried inside. Further, the large number of holes (5) formed in the reinforcing member (4) are formed in a honeycomb structure or a net structure, or are made of metal, a polymer compound, or the like. Further, the plurality of holes (5) may be filled with an elastic member (3) or a member different from the elastic member (3).

ことができる。Since the elastic member (3) and the members loaded into the many holes (5) of the reinforcing member (4) are integrally formed in close contact with each other, the elastic member (3) is prevented from vertical and Since expansion and contraction in the horizontal direction can be reasonably suppressed, the rigidity of the vibration isolation and seismic isolation material can be lowered. Therefore, the elastic member (3) can expand and contract in the vertical and horizontal directions, and can absorb strong vertical and horizontal vibrations caused by earthquakes and the like.
さらに、前記多数の孔（５）の形状及び装填される部材

とができる。Furthermore, by changing the shape of the large number of holes (5) and the material of the loaded member, the vibration isolation and seismic isolation performance can be changed.

免震作用が有効に働く。The large number of holes (5) are filled with an elastic member (3) or an elastic member (
A member made of a different material from the elastic member (3) is loaded, and the elastic member (
3) is formed so as to be in close contact with and integrated with it. Since the reinforcing member (4) and the members loaded into the many holes (5) are in close contact with the elastic member (3), the elastic member (3) can expand and contract due to vibrations in the vertical and horizontal directions. Since the elastic member (3) can be strengthened and suppressed, the rigidity of the elastic member (3) can be lowered, so that the elastic member (3) can be expanded and contracted and can absorb vibrations caused by earthquakes, etc. , vibration isolation in buildings, etc.
Seismic isolation works effectively.
