（課題を解決するための手段） 前記の目的を達成するため、本発明に係る床防振装置
は、床と、同床上にばねを介して支持されたマスとの間
に、減衰性の高い弾性体を介装して構成されている。(Means for Solving the Problems) In order to achieve the above object, the floor vibration isolator according to the present invention has a high damping property between the floor and the mass supported on the floor via a spring. It is configured by interposing an elastic body.

る。(Operation) Since the floor vibration isolator according to the present invention is configured as described above, the spring for supporting the mass on the floor and the elastic body having a high damping property interposed between the mass and the floor. The sum of rigidity and
By adjusting the mass of the mass, the floor damping device can have an appropriate natural period, and by adjusting the amount of the elastic body, an appropriate damping coefficient can be obtained.
而して床が上下に振動すると、マスは上下に大きく振
動し、前記弾性体は圧縮力及び引張力を受け、振動を減
衰させる。When the floor vibrates up and down, the mass vibrates up and down, and the elastic body receives a compressive force and a tensile force to damp the vibration.
（実施例） 以下本発明を図示の実施例について説明する。(Examples) The present invention will be described below with reference to illustrated examples.
（１）は床（２）上に固定された容器で、その底部
（1a）上にマス（３）をコイルばね（４）で上下方向に

る。(1) is a container fixed on the floor (2), and supports a mass (3) on the bottom (1a) of the container in the vertical direction by a coil spring (4), and at the same time, supports the mass (3) and the bottom (1a). ) Is inserted into the mass (3) and the bottom (1a) by inserting an elastic body (5) having a high damping property, for example, an elastomer such as high damping rubber or silicone rubber into the upper and lower surfaces of the elastic body (5). Glue each one.
更に前記マス（３）の側面と前記容器（１）の側壁
（1b）との間にも弾性体（５）が介装される。Further, an elastic body (5) is also interposed between the side surface of the mass (3) and the side wall (1b) of the container (1).
図中（６）はボルト（７）を介して前記マス（３）の
取付けられる周波数調整用マスである。In the figure, (6) is a frequency adjusting mass to which the mass (3) is attached via a bolt (7).

計重量と、コイルばね（４）と弾性体（５）と（５′）
による剛性から、図示のマスダンパーの固有周波数が設
定される。Thus, the total weight of the mass (3) and the frequency adjusting mass (6), the coil spring (4), the elastic bodies (5) and (5 ').
The natural frequency of the mass damper shown in the figure is set from the rigidity due to.
上記したように構成したマスダンパーが取付けられた
床が上下に振動すると、マス（３）は上下に大きく振動
し、同マス（３）の底部の弾性体（５）は交互に圧縮
力、引張力を受け、振動を減衰させる働きをする。When the floor with the mass damper constructed as described above vibrates up and down, the mass (3) vibrates greatly up and down, and the elastic body (5) at the bottom of the mass (3) alternately compresses and pulls. It receives force and acts to damp vibrations.
同時に前記マス（３）の側部の弾性体（５′）は床の
振動に伴って剪断変形を生起し、底部の弾性体（５）と
同様に、固有周期、減衰定数の調整に寄与するととも
に、マス（３）の側方への移動を制限する。At the same time, the elastic body (5 ') on the side of the mass (3) causes a shear deformation due to the vibration of the floor, and like the elastic body (5) on the bottom, contributes to the adjustment of the natural period and the damping constant. At the same time, the lateral movement of the cell (3) is restricted.
なお前記弾性体（５′）はマス（３）の変形分だけ圧
縮しておけば、接着する必要はない。The elastic body (5 ') need not be adhered if it is compressed by the amount of deformation of the mass (3).
更に前記弾性体（５）は第５図に示すように、小さな
ユニツトに区分され、互いに離隔して配置される。これ
は前記弾性体（５）が圧縮された場合、横方向に膨らむ
ため、そのスペースを確保し、相隣る弾性体（５）が干
渉しないようにするためである。Further, as shown in FIG. 5, the elastic body (5) is divided into small units and arranged apart from each other. This is because when the elastic body (5) is compressed, it expands in the lateral direction, so that a space is secured and the adjacent elastic bodies (5) do not interfere with each other.
