Description

[Detailed Description of the Invention] <<Industrial Application Field>> This invention relates to a vibration control support for a structure, and particularly to a support for controlling minute vibrations applied to a structure.

《Background of the idea》 As is well known, earthquakes occur frequently in Japan, and various earthquake-proofing measures are applied to the building structures in Japan.In particular, nuclear power plants and other structures are subject to fatal damage if they are damaged. The entire structure is earthquake resistant.

On the other hand, with recent advances in building materials and construction technology, structures are becoming larger in span, and especially in integrated circuit manufacturing factories, there is an extremely high demand for internal cleanliness.

The reason for this is that technological innovation is making remarkable progress in this field, production equipment is frequently updated, and flexibility in accommodating equipment is required.

By the way, in this type of manufacturing factory, micro ICs
Vibration countermeasures were an extremely important issue in printing patterns.

Therefore, in the past, like nuclear power plants,
While the entire factory building is equipped with earthquake-proofing measures, the sources of vibration within the factory are also covered with anti-vibration rubber to prevent vibrations from being transmitted to the surrounding area.

However, even with the above-mentioned countermeasures, micro-vibrations are transmitted to each floor through the slabs and pillars of the structure, and in the current situation where IC patterns are on the order of microns, it is not an effective vibration countermeasure. Nakatsuta.

As a solution to this problem, for example, this can be prevented by increasing the diameter or thickness of the columns, beams, and slabs of the structure, but this means that by increasing the span, these items have become larger in diameter and thicker, and then stacked on top of each other. This would be extremely uneconomical.

Moreover, such means of increasing the diameter or thickness of columns and beams of a structure have the disadvantage that the usable space of the structure is reduced.

This idea was made in view of the above-mentioned background, and its purpose is to reduce the slight vibrations of the structure without increasing the diameter of the structure's columns or increasing the thickness of the beams and slabs. The purpose is to provide vibration control support that can be controlled with a relatively simple configuration.

<Means for Solving the Problem> In order to achieve the above object, this invention is a support that is installed vertically between the floors of a structure, and this support is in contact with the top and bottom of the floors, respectively. and a cylindrical column extending in the vertical direction with these abutting sections provided at both ends, the abutment section being provided so as to be freely protrusive and retractable with respect to the column, and , characterized by having an elastoplastic material.

Note that the elastoplastic material used in this invention refers to special rubber, ferrite, etc.

<<Embodiments>> Hereinafter, preferred embodiments of this invention will be described in detail with reference to the accompanying drawings.

1 and 2 show an embodiment of a vibration control support for a structure according to this invention.

The support 10 shown in the figure is installed between an upper floor beam 12 and a lower floor beam 14 constructed on the upper and lower floors of a structure, and is configured as follows.

That is, the control support 10 includes a hollow cylindrical support 16 and a pair of contact parts 17 fixed to both ends of the support support 16, and each contact part 17 is made of an elastic-plastic material 18 such as special rubber or ferrite. , 18.

In this embodiment, as shown in FIG.
Screws are installed at both ends of the support column 16, and a threaded rod 20 is screwed onto the screws, and a mounting plate 22 is fixedly attached to one end of the threaded rod 20.
The elastoplastic material 18 is adhesively fixed between the and the backing plate 24, and by turning the threaded rods 20 at both ends, the contact portion 17 moves in and out of the support column 16, thereby causing the control support 10 to move. It can be installed in any location.

The control support 10 is installed at the upper abutment part 1.
With the threaded rod 20 of No. 7 loosened, place it upright at an appropriate location on the lower floor beam 14, turn the threaded rod 20 on the upper end side,
The contact portions 17 are extended upward, and above each contact portion 17,
The lower end backing plates 24, 24 are the upper and lower floor beams 12, 14
This is done by making contact with the surface of the

In addition, the installation location may be, for example, beams 12 and 1 on the upper and lower floors.
They can be placed in rows at appropriate intervals along the 4 spaces, or they can be placed in arbitrary positions instead of in rows.
Furthermore, it may be provided between a slab and a beam or between slabs.

Now, when the vibration control support 10 configured as described above is installed between the floors of a structure, even if slight vibrations generated elsewhere in the structure are transmitted through beams, columns, slabs, etc. The elastoplastic material 18 provided on the control support 10 absorbs this.

Therefore, in the space in which the control support 10 is installed, it is possible to eliminate the influence of minute vibrations.

Also, the control support 10 itself does not need to carry the load of the structure. Therefore, it is sufficient for the support column 16 to have a proof strength to press the elastic-plastic material 18 toward the installed member, and the support column 16 can be made to have the minimum cross-sectional area necessary for this purpose.

FIG. 3 shows another embodiment of this invention,
Only the characteristic points will be explained below.

That is, this embodiment is characterized in that an oil damper 26 is built inside the column 16.

With this configuration, in addition to the effects of the above embodiment, when the upper floor beam 12 (or slab) or the lower floor beam 14 (or slab) vibrates independently, the control support 10 allows the vibration of the other beam. Alternatively, when vibrations are transmitted to the slab, it is possible to attenuate the vibrations.

In the above embodiment, the pillar 16 has a hollow cylindrical shape, but it is of course not limited to this, and may have a rectangular cylindrical shape or a solid body. For example, it may also be used as a support member for a partition wall. .

Further, the means for expanding and contracting the support column 16 is not limited to the above-mentioned one, and may be expanded and contracted using, for example, a biasing means such as a jack.

Furthermore, the control support 10 of the present invention includes reinforcing bars,
Can be used for various structures such as steel concrete structures.

<<Effects of the invention>> As explained in detail in the embodiments above, the vibration absorbing support according to the present invention has a relatively simple structure of a pair of abutting parts and a support having an elastoplastic material. If installed between the floors of a structure, it is possible to control the minute vibrations transmitted between the structures without making any changes to the configuration of the structure itself.

Furthermore, the struts that support the elastic-plastic material have the smallest cross-sectional area and have little effect on the available space.

Therefore, these effects make the control support of the present invention particularly suitable for large-span structures such as IC factories, and of course can also be applied to existing structures.

Furthermore, if the control support is configured to be expandable and retractable, it can be installed at any location, so there is no restriction on the degree of freedom of space usage when changing production equipment or the like.
