以下、本発明の好適な実施例について、図面を参照にし
て詳細に説明する。(Embodiments) Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.
図は、免震ビル1の概略を示し、地盤2上に免震積層ゴ
ム支承3を介して建物本体4が支持しである。The figure schematically shows a seismic isolation building 1, in which a building body 4 is supported on the ground 2 via seismic isolation laminated rubber bearings 3.
更に、建物本体4の基部側面に基部加力用のアクチュエ
ータ5を設置している。Further, an actuator 5 for applying force to the base is installed on the side surface of the base of the building body 4.
アクチュエータ5は油圧シリンダー内の中立位置にピス
トンが保持され、このピストンに一体的に接続されたロ
ッド6が外部に臨み、ロッド6の移動方向はサーボ弁を
具えるサーボバルブ7で決められている。In the actuator 5, a piston is held at a neutral position within a hydraulic cylinder, a rod 6 integrally connected to this piston faces outside, and the direction of movement of the rod 6 is determined by a servo valve 7 provided with a servo valve. .
サーボバルブ7は速度センサーや加速度センサ、変位計
等の出力データに基づいて制御される。The servo valve 7 is controlled based on output data from a speed sensor, acceleration sensor, displacement meter, etc.
制御の方式には種々あるが、物質が一点に集中したもの
として考え、建物を一質点系として考えた最適制御力に
よる制震手段が今日では多く発表されている。Although there are various control methods, many vibration damping methods have been announced today that utilize optimal control force that considers materials concentrated at one point and buildings as a system of one mass point.
上記アクチュエータ5に加圧された油を供給するための
油圧源は、円筒体を鉛直に設置した容器8内に油を入れ
、この容器8の半径と同径の円盤状重錘9を容器8の上
方から嵌入している。A hydraulic source for supplying pressurized oil to the actuator 5 is a container 8 in which oil is placed in a vertically cylindrical container 8, and a disc-shaped weight 9 having the same diameter as that of the container 8 is inserted into the container 8. It is inserted from above.
すなわち、容器8は油圧タンクであって、重錘9は容器
8内を上下に運動するピストンに近似した形状をなす。That is, the container 8 is a hydraulic tank, and the weight 9 has a shape similar to a piston that moves up and down within the container 8.
容器8内の油は下部からサーボバルブ7を通り・アクチ
ュエータ5に至る。容器8と重錘9とで油圧アキュムレ
ータ10を構成しているのである。The oil in the container 8 passes through the servo valve 7 from the bottom and reaches the actuator 5. The container 8 and the weight 9 constitute a hydraulic accumulator 10.
容器8の半径をアクチュエータ5の内径よりも充分大き
くすることにより、重錘9の重さによって生じる容器8
内部の圧力よりも充分に高い圧力でもってロッド6を連
動させ得る。By making the radius of the container 8 sufficiently larger than the inner diameter of the actuator 5, the container 8 caused by the weight of the weight 9
The rod 6 can be moved with a pressure that is sufficiently higher than the internal pressure.
アクチュエータ5はサーボバルブ7の動きに追従して内
部のピストンが中立点を基準にして左右に運動する。そ
の運動力がロッド6を通じて建物本体4の運動を減衰さ
せる方向に作用する。The actuator 5 follows the movement of the servo valve 7, and its internal piston moves left and right with respect to a neutral point. The kinetic force acts through the rod 6 in a direction that damps the movement of the building body 4.
このアクチュエータ5の運動に伴ってアキュムレータ1
0内の油は漸次に外部に排出される。それ故、アキュム
レータ10内の油量は平均的な地震動時間を充分に上回
る程度が必要である。As the actuator 5 moves, the accumulator 1
The oil inside the tank is gradually discharged to the outside. Therefore, the amount of oil in the accumulator 10 needs to be sufficient to exceed the average seismic motion time.
また、建物本体4の質量を考えた場合、アクチュエータ
5の油圧は200kg/c−程度になるように重錘9の
重さを選ぶ。Furthermore, considering the mass of the building body 4, the weight of the weight 9 is selected so that the oil pressure of the actuator 5 is approximately 200 kg/c-.
地震力がおさまり、アクチュエータ5が作動しなくなっ
たような時点で、クレーン等で重錘9を持ち上げ、使用
した油を回収するなどして再び容器8内に油を充填し、
重錘9をセットしなおせばよい。When the seismic force subsides and the actuator 5 no longer operates, the weight 9 is lifted with a crane or the like, the used oil is collected, and the container 8 is filled with oil again.
All you have to do is reset the weight 9.
