Incidentally, reference numeral 205 in the figure denotes a shock absorber provided between the slab 201 and the floor material 202 and absorbing vibration energy.

In the vibration-isolated floor structure using the curved guide device or the three-dimensional guide device as described above, the floor material 202 is stably placed at the steady position of the guide device 203 in the absence of vibration such as an earthquake. Even if the building is located and the building vibrates due to an earthquake or the like, the slab 201 and the floor material 202 are vibration-insulated by the guide device 203, and large vibrations cannot be transmitted to the floor material. .

Here, when the three-dimensional guide device or the like is installed between the slab and the floor material, if the three-dimensional guide device has a large height, it is placed due to the limitation of the ceiling height. The height of the article is limited, and it becomes difficult to install the article to be placed in a stable manner. Moreover, since a space is formed between the floor material and the slab, the vibration on the floor material easily resonates. There is a problem of becoming.

Therefore, an object of the present invention is to provide a curved guide device and a three-dimensional guide device which have a small height dimension and generate less noise.

In the three-dimensional guide device 120 of the embodiment configured as described above, the curve guide devices 110U, 11 are provided.
By stacking 0D to form a guide device that can move along a spherical surface in a three-dimensional manner, the overall structure can be made thinner, the structure is simple, the manufacturing is easy, and the cost is low. Become.

Further, since the elastic members 115U and 115D are attached to the track rails 111U and 111D, the elastic members 115U and 115D are deformed even when the flatness of the mounting surface is poor, so that the shape of each rail is changed. It is possible to maintain and perform smooth curve guidance, and a three-dimensional guide operation can be performed by combining the two. Further, even if vertical vibration is applied by the elastic members 115U and 115D as the initial vibration of the earthquake and vertical load changes in the three-dimensional guide device, the elastic members 115U and 115D are also generated.
As a result, the fluctuation of the load is buffered, the shocking load is not applied to the curved guide device and the three-dimensional guide device, and it is possible to prevent the three-dimensional guide device from being damaged by the initial vertical vibration.

Further, the main structure is a rail 111 having a plate structure.
Since the elastic members 115U and 115D are attached to the U and 111D, the local bending near the ball rolling groove of the plate and the elastic force of the elastic members 115U and 115D cause
The vertical vibration can be effectively absorbed, and the mounted object and the moving article can be protected from the damage due to the shocking vertical load. Then, the sound accompanying the rolling motion is absorbed and silenced by the elastic members 115U and 115D while being transmitted, so that the operation can be silenced.

By arranging such a three-dimensional guide device between the slab and the floor material so as to spread in a plane, important facilities in a building such as a computer system and a cultural property storage room, the cultural property itself It is possible to realize a vibration-isolated floor structure to be installed on the floor such as.

Therefore, when the flat guide device and the three-dimensional guide device according to the present invention are interposed between the slab and the floor material, a large horizontal vibration can be released and the vertical vibration can be effectively damped. it can. When there is no vibration such as an earthquake, the floor material is stably positioned at the steady position of the guide device, and even if the building vibrates due to an earthquake or the like, the guide device is placed between the slab and the floor material. It is possible to prevent large vibrations from being transmitted to the floor material by moving the floor material in one direction with respect to the slab and then inverting it to repeat the above process to attenuate the vibration. ,
Eventually, there is an effect that it is possible to configure a vibration-isolated floor structure that stops at the stationary position which is the lowermost part of the guide device and does not damage the articles placed on the floor material.
