吸収型積層ゴム支承に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertical shock absorbing type laminated rubber bearing in which a device for absorbing a vertical shock is added to a conventional laminated rubber bearing.

【従来の技術及び発明が解決しようとする課題】一般に
通常の地震は、周期が１秒以下の短周期成分が卓越して
いる場合が多い。非免震の中低層ビルは、地震波の周期
に近い固有振動数であるため、大きな地震力を受ける。
建物の固有周期を超高層並に延ばして、地震力を低減し
ようとするのが従来の積層ゴム支承の考え方である。2. Description of the Related Art In general, an ordinary earthquake often has a short period component having a period of 1 second or less. Non-seismic low-rise buildings are subject to large seismic forces because they have natural frequencies close to the period of the seismic wave.
The idea of conventional laminated rubber bearings is to reduce the seismic force by extending the natural period of the building to the level of a super-high-rise building.
【０００３】図３は、免震装置例えば積層ゴム支承を用
いた場合、固有振動周期がＴ0 からＴ1 に延びると、応
答加速度が相応に低減することを示した概念図である。FIG. 3 is a conceptual diagram showing that, when a seismic isolation device such as a laminated rubber bearing is used, when the natural vibration period extends from T 0 to T 1 , the response acceleration is correspondingly reduced.
【０００４】図４は従来の積層ゴム支承の概念図で、薄

になる。従って水平方向の剛性が小さいため水平方向に
軟らかく地震時の応答加速度を低減するに有効であるが
上下方向に対しては非免震の場合と略同じ挙動をとるこ
とになる。FIG. 4 is a conceptual view of a conventional laminated rubber bearing, in which thin rubber and an iron plate are alternately overlapped and vulcanized and bonded, whereby the rigidity in the horizontal direction is smaller and the vertical load is smaller than when there is no iron plate. However, the rigidity is increased because the iron plate restrains an attempt to spread at a right angle thereto. Accordingly, the laminated rubber bearing has characteristics required to support a long-term load of a building, which has a long cycle in the horizontal direction and is stable in the vertical direction. Therefore, since the rigidity in the horizontal direction is small, it is soft in the horizontal direction and is effective in reducing the response acceleration in the event of an earthquake. However, the behavior in the vertical direction is almost the same as in the case of non-seismic isolation.
【０００５】しかるに、先の阪神大震災の報告によれば
最大加速度が水平で８３３Gal 上下で最大５０７Gal と
いわれ、水平動の大きさもさることながら、上下動も極
めて大きかったことになる。記録のなかには水平加速度
よりも上下加速度の方が大きな値を示したものもあると
言われる。However, according to the report of the Great Hanshin Earthquake, the maximum acceleration is said to be 833 Gal in the horizontal direction and 507 Gal in the vertical direction, which means that the vertical motion is extremely large as well as the horizontal motion. It is said that some of the recordings showed a higher vertical acceleration than a horizontal acceleration.
【０００６】振動時間は水平、上下とも１０〜１５秒程
度と短く、略同時に観測されているという。瞬間的に大
きな力が水平、上下方向共かかったと言えよう。The vibration time is as short as about 10 to 15 seconds both horizontally and vertically, and it is said that they are observed almost simultaneously. It can be said that a large force was instantaneously applied to both the horizontal and vertical directions.
【０００７】そこで、このような都市直下型地震に対す

する。The present invention absorbs such instantaneous initial shocks in the vertical direction, extends the natural vibration period for vertical vibrations after the initial shocks, reduces vertical vibrations, and simultaneously reduces horizontal vibrations. It is an object of the present invention to provide a vertical shock absorbing laminated rubber bearing that exhibits a conventional vibration reducing effect.
