Best mode for carrying out the invention

The present invention will be described in detail with reference to the accompanying drawings.

The vibration-free structure according to the present invention is, in principle, a suspension device having a restoring force in three directions.

, OMPI It is established by applying the three-dimensional suspension device. FIG. 1 and FIG. 2 show one embodiment of the ternary suspension device.], Which is disposed on one side of the support a or the support b A first component member (and a second component member (B) disposed on the other side and having a concave surface 1) and rotatably held by the first component forest (A); And the concave surface 1 of the second component member (B).]) The contacting sphere 2 and either the first component member (A) or the second component member (B) are supported by the support surface. a The elastic suspension device 3 elastically supported on the first component member (A) is slidably held outside the first component member (A), and the second component member (B) is hinged. The holding device 4 of the second component (B) is pressed so that the concave surface 1 of the second component (B) and the ball 2 held by the first component (A) are pressed against each other. Second component And a tensioning device 5 for pulling the material (B) in one direction.] In particular, the holding device 4 is a supporting shell slidable with respect to the outer periphery of the first component (A). The supporting cylinder ό and the second component member (Β) are connected by a plurality of equal-length ring rods 7, and these ring-dedicated 7 is connected at both ends via a universal joint 8, so that the second component (Β) maintains contact with the sphere 2 on its concave surface 1. It can be moved in parallel. According to the above-described structure, the three-dimensional suspension mounting amount is such that the first component (.) And the second component (Β) are parallel to the holding surface a. And in mutually orthogonal two-dimensional directions, that is, relative to the X or Y direction.

O PI When a deviation occurs, the sphere 2 rolls on the concave surface 1 of the second component (B). At this time, a centripetal force acts between the two to move the supported member b to the original position. It generates a restoring force to return, and returns the supported member b to its original position.Also, the vibration in the ヱ direction perpendicular to the supporting surface of the supported member b suspended on the supporting member a The elastic suspension device 5 is cut off or absorbed by the elastic body 9 such as a fork spring, for example, so that the elastic suspension device 5 can expand and contract in the X, Υ, and 三 directions as a whole. That is. FIGS. 5 and 4 show the structural principle of the seismic-free structure according to the present invention]), and the inner wall 11 for forming a protection space for the protection inside the outer wall 10 is accommodated. ^One or more three-dimensional suspension devices 12 are installed between the outer wall 1Q and the inner wall 11 so that the inner wall 11 is hollow inside the outer wall 10. And the inside of the space 13 formed between the outer wall 10 and the inner wall 11 is made to be vacuum or atmospheric pressure.] The vibration generated outside the outer wall 10 is It is intended to be transmitted into the protected space of the wall 11.

Next, an embodiment of the vibration-free structure according to the present invention will be described. Figures 5 and 6 show an actual travel example of a seismic-free reactor building as a fixed seismic structure, and Figs. 7 and 8 show the same external view. This shows another embodiment of a reactor building having a different shape, and has a double-wall structure composed of an outer wall 14 and an inner wall 15. The outer wall 14 is hollowly held by the three-dimensional suspension device 1 内部.

OMPI

, 删 The lower part 14a is a three-dimensional base where the lower part 14a has a supporting function and a wall function because it does not generate vibration and inclination due to wind pressure etc. due to external weather changes. In addition, the upper part 14 b is configured as a windproof roof having only a light wall function, and is fixed to the ground 18 on the artificial rock 17 through the artificial rock 17. The outer wall 14 is entirely made of steel or steel reinforced concrete, partly steel reinforced concrete)) or steel reinforced concrete. The structure can be combined with the support function and the wall function, such as a steel frame structure (metal structure in the other part), and a three-dimensional suspension directly on the foundation. It is also possible to connect the cushioning device 1, and use a material having only a large wall function for forming an internal space as the external wall 14. 1 9 is the ground surface. The inner wall 15 is constructed by applying the current reactor building almost as it is. However, it is possible to appropriately change the position for providing structural consistency when supporting the outer wall 14, for example, the position of a pillar, a and the like. In other words, since the non-seismic reactor building related to the invention has a building scale, its structural mechanical contents are rational and economical, so it is considered as a whole. Must be configured as a consistent structure. In this drawing, the inner wall 15 is configured so that the whole has both the supporting function and the wall function, but it is necessary that the J? Even if it is configured so that it has the same function and the other part has only the wall function, the protective body can be placed on the outer wall with a three-dimensional suspension device.

O.VPI Alternatively, it is possible to connect to the foundation and make the inner wall 15 a frame having only a support function without a wall function, or a structure using the inner wall 15. In order to prevent the movement of the outer wall 14 from being transmitted to the inner wall 15, it is ideal to evacuate the space 20 formed between the outer wall 14 and the inner wall 15. It is. However, since the inner wall 15 has a sufficient mass, there is no problem even at normal atmospheric pressure. In addition, as a method of preventing vibrations generated inside, the equipment that is the source of vibrations is supported on a base with a three-dimensional suspension device, or periodic vibration is generated. It must be prevented by not doing so.

If the inner wall 15 has a structure having only the wall function, it is necessary to evacuate the space 20 between the inner and outer walls, so that the portion can be omitted. However, it is significant when used as a radiation barrier. In addition, the outer wall 15 is configured as a steel structure having sufficient seismic strength, and it does not hinder itself even if it vibrates. Sir. The fixed seismic structure can be applied not only to the above seismic reactor building but also to precision factories and other buildings.

Between the outer wall 24 and the inner wall 250 Then, one or two or more three-dimensional suspension mounts 2 ό are weighed, and the inner wall 25 is suspended in the outer wall 24 in a hollow manner. Space 27 'formed between inner and outer walls

O PI

— WiPO It is not always necessary to use a vacuum, and for an ordinary ambulance, sufficient performance can be obtained at atmospheric pressure. In this embodiment, the outer wall 24 has a function of supporting the entire inner wall 25 and a function of blocking external weather changes and noise at the same time. The part has both the holding function and the wall function at the same time, and the other part has only the supporting function or the wall function, and further has only the supporting function that is entirely formed by a frame etc. It can be configured as the original. The inner wall 25 also has both a support function to support the protective material and a wall function that plays a role of heat insulation and noise isolation, and a part of the inner wall 25 has the support function and the wall function. The other part has only the supporting function or the wall function, and the other part has only the supporting function that came out of the frame etc. In addition, the protection can be directly supported by the three-dimensional suspension device 20 on the outer wall 24, and the inner wall 25 can be omitted. The entrance door is provided with a door 28 and an inner door 29 on the outer wall 24 and the inner wall 25, respectively. By using double doors, it is possible to improve the quality of the interior in terms of spatial functions such as heat insulation and sound. In order to prevent the vibration generated in the inner wall 25 from being transmitted to the bed 50 of the sick, the bed 50 is connected to the inner wall with a three-dimensional suspension device 2 ό. since the 2 Tsutebe' de 3 0 by _c to this to support in the 5 is in and the child to set ¾ a three-Motosa scan pen tio NSoryou 2 ό to double between the outer wall 2, It will be a high-performance seismic bed. Occurs within S ¾ 25

OMPI There are two types of vibration: mainly due to the movement of humans and the operation of the medical device S1. 3 3 is supported on the inner wall 25 by the three-dimensional suspension device 2 、, and the medical device is operated by the medical device 31. 5 is also prevented by supporting the inner wall 25 with the three-dimensional suspension device 2 装置. S 4 is a vehicle body, and 3 5 is a wheel. Non-stationary ¾ seismic-free structures can be applied to the formation of protected spaces outside the above-mentioned ambulance sickroom for ambulances, transport trucks and other automobiles, railcars, ships, and aircraft. It is possible.
