I have . In this vibration isolator 2, only the lower end 20 of the curved portion 2A is usually used (when no load is applied to the floor).
It is in a state of being in contact with the floor base surface 1 and only the lower end portion 20 is bent and deformed by the floor impact force when a specific object is dropped, effectively absorbing the impact energy, and preventing noise downstairs. Thus, the sound insulation effect can be improved.

ための孔２１が開口されている。The compressing section 2B does not significantly displace (vertically move) the floor surface when the load exceeds a specific range of load, for example, when moving furniture or heavy objects placed on the floor. It is intended to improve the livability by effectively suppressing the shaking and sinking of the building. The compressing unit 2B of this embodiment, as shown in FIG. 2, is formed in a substantially cylindrical shape to maintain a constant gap d to the inner peripheral surface of the curved portion 2A, connected to the curved portion 2A at the top It is configured to be integrally connected by a portion J, and a hole 21 for the support leg 3 to enter is opened at the center.

The male screw portions 30 and 31 are threaded in opposite directions. For example, a one-letter or ten-letter groove is engraved on the upper surface of the support leg 3, and a screwdriver or the like is engaged with the groove to turn the groove. By moving the floor, the level of the floor base material 4 can be freely changed to adjust the floor height.

This will be described with reference to the graph I in FIG.
The remaining II and III in the graph shown in FIG. 3 show the characteristics of the conventional vibration damping material. For example,
When a light specific object having a floor impact force of f 1 or less is mistakenly dropped on the floor, the floor (floor base material 4) hardly moves up and down as shown in graph I, but the impact energy also decreases. Since it is not so large, the propagation energy to the downstairs is small, and the sound insulation effect has almost no problem.

<F 3, provided that expansion f 2 is the least floor impact force generated during running around the person) acts on the floor, the lower end portion 20 of the impact force f 2 in just bend 2A in this region to the outside 2 Since the displacement is large in the opening direction, as shown by the decrease in the slope of the graph I in that range, the floor also moves up and down in accordance with that, and efficiently absorbs the impact energy.
Therefore, such running of people and JIS A1418
The sound is effectively isolated from the heavy impact source, and the propagation of noise downstairs is greatly suppressed. In this way, the floor impact force is due to the large expansion deformation operation to the outside of the lower end portion 20 of the curved portion 2A to the previous f 3, curved deformation until the lower surface and the same level of compression unit 2B.

機構として作用する。However, if a relatively heavy heavy object acts on the floor (floor base material 4) as an impact force f (f <f 3 ), it is difficult.
The bending energy of the bending portion 2A and the compression portion 2B are absorbed by the compression deformation in the vertical direction. That is, since so as to absorb the impact energy by both the compressing unit 2B and the curved portion 2A in this case, vertical movement is the specific object of the bed (underfloor member 4) as shown in the graph I There to be significantly suppressed compared with the case of the dropping, a bending portion 2A and the compressor unit 2B acts as a stopper mechanism in other words.

Incidentally, the lower end portion 2 0 of the curved section 7A Ru Oh bent inward. Further, as shown in FIG. 5, the vibration damping member 8 may be one in which a curved portion 8A and a compressed portion 8B are formed in a reverse inner / outer positional relationship.

向上につながる。As described above, according to the present invention, in order to particularly efficiently absorb the floor impact energy generated when a specific range of load acts on the floor, the present invention is particularly applied to such a load. It has a curved portion that increases displacement, just by forming the characteristic as the load range is consistent with the impact force on running around and weight impact source of human, noise daily frequent Can be effectively absorbed, which in turn leads to an improvement in sound insulation performance for downstairs and the like.

For example, by placing the furniture so that it does not significantly displace the floor surface when placing furniture or moving heavy objects, it is possible to prevent difficulty in walking due to shaking of the floor, etc. Also leads to improvement.
