のスペースが必要となる。However, if the foundation concrete surface and the supporting slab surface are uneven, a gap is formed between the concrete surface and the supporting slab and the building cannot be stably supported. Further, since it is necessary to install a separate damper, the device becomes large in size and a certain space is required in the height direction.

The sphere begins to roll between the moving members, and the damping plate is sheared and deformed by the surface friction between the sphere and the damping plate and the pressing force of the sphere, so that the damping force is exerted. Furthermore, since the frictional resistance with the damping plate when the sphere rolls also acts as a damping force at the same time, a high damping effect is exhibited by a combination of these.

らの組み合わせによって高い減衰効果を発揮する。In the state shown in FIG. 1, when the floor slab 12 moves to the left due to an earthquake or the like, the double floor material 16 relatively moves to the right as shown in FIG.
4 starts rolling to the right between the floor slab 12 and the double flooring 16. At this time, the damping plates 11 and 13 compressed and deformed by the sphere 14 have a surface friction force with the sphere 14 and the sphere 14
Since it is sheared and deformed by the pressing force of the damping force, the damping force is exerted, and further, the damping plates 11 and 13 when the sphere 14 rolls.
Since the frictional resistance between and also acts as a damping force at the same time, a high damping effect is exhibited by a combination of these.

Furthermore, the damping mechanism described above not only prevents earthquakes, but also eliminates traffic vibration obstacles (resonances caused by the natural period of the building), and also causes children on the upper floor to bounce off and thus the solid propagating sound transmitted to the lower floor. You can also mute it.

初めて保持部22に当たるようになっている。As shown in FIGS. 7 and 8, the holding plate 20 is a plate material formed of hard plastic, lightweight concrete, a PC plate or the like, and is designed to have a plate thickness that does not contact the double floor material 16. . In addition, the holding plate 20 is formed with circular holding portions 22 that penetrate the upper and lower surfaces at predetermined intervals. The inner diameter of the holding portion 22 is larger than the outer diameter of the spherical body 14, and the spherical body 14 is surrounded in a non-contact state. By this, when the sphere 14 begins to roll,
It is designed to hit the holding portion 22 for the first time.

In this embodiment, when the sphere 14 starts rolling, it moves while pushing the holding portion 22, so that frictional resistance is generated between the holding plate 20 and the floor slab 12, which is high in combination with the damping action of the damping plates 11 and 13.

As a result, the spherical body 14 sneaks into the lower surface of the holding plate 20 and undergoes large shear deformation. Further, in the holding portion 162 shown in FIG. 10, since the top portion is expanded and contracted so as to wrap the sphere 14, the sphere 14 does not jump out of the holding portion 162.

However, if the seismic isolation structure of this embodiment is applied, a spherical body can be used depending on the weight of the building. An ideal seismic isolation structure can be obtained by changing the sphere diameter and the number of spheres, and the material and thickness of the damping plate.
