本発明は、電磁シールドルーム用パネルおよびその固定
方法に関する。DETAILED DESCRIPTION OF THE INVENTION (Objective) The present invention relates to an electromagnetic shielding room panel and a method for fixing the same.
最近、医療機器、ＯＡ機器等の精密電子・電気機器の電
磁波、磁気による誤動作や、計測ミスを防止することが
重要視され、シールドルームの施工が増大している。Recently, it has become important to prevent malfunctions and measurement errors caused by electromagnetic waves and magnetism in precision electronic and electrical equipment such as medical equipment and OA equipment, and the construction of shielded rooms is increasing.
ところが、電磁波シールドを施す場合は、高周波領域で
の磁界分が主体となるため、アルミニウムや銅等の高導
電材が使用されるが、磁界シールドの場合は低周波領域
での磁界分が主体となりアモルファス金属やパーマロイ
等の高透磁率材が使用され、電磁波シールドとは全く別
の扱いとなっていた。However, when applying electromagnetic shielding, the magnetic field is mainly in the high frequency range, so highly conductive materials such as aluminum or copper are used, but in the case of magnetic field shielding, the magnetic field is mainly in the low frequency range. Highly permeable materials such as amorphous metal and permalloy were used, and they were treated completely differently from electromagnetic shielding.
特に、ＭＲＩやコンピュータルームにおいては、ベース

電界に対して別別の施工をしていたためコストアップと
なっていた。In particular, in MRI and computer rooms, consideration must be given to base manufacturer owners (5G or less), magnetic field shielding to the limit (0.5G or less) that does not cause computer malfunction, and electromagnetic wave interference (for example, MHI In the case of
Separate construction was required for electric fields, which increased costs.

め、かなりの工数を要し、コスト高となっている。Next, the main construction method for these magnetically or electromagnetically shielded rooms is partition-like construction in which they are stretched over a building frame. In other words, the frame is made of lightweight steel or wood, and plywood or concrete panels are pasted on top of it.
Materials that are shielding materials (copper aluminum for electric fields,
In the case of a magnetic field, amorphous or permalloy) is fixed, a plywood or concrete panel is placed on top of it for finishing, the joints are sealed, and the finishing is done by painting, which requires a considerable amount of man-hours and is costly. It is high.
本発明は、前述した従来技術の不具合を解決し、簡単に
施工できるシールド材を提供することを解決すべき課題
とする。An object of the present invention is to solve the problems of the prior art described above and to provide a shielding material that can be easily constructed.

提供する。(Structure) In order to solve the above-mentioned problems, the present invention consists of a rectangular frame made of L-shaped angles and pipes, and on the frame, an iron plate,
A silicon steel plate, an aluminum plate or a copper plate is placed, and its end is 90mm along the figure 12 angle and the pipe.
6. To provide an electromagnetic shielding panel having a structure in which a soft magnetic amorphous alloy is placed on a bent box shape.
好ましくは軟磁性非晶質合金が厚さ５〜１００μｍ、ア
スペクト比１０〜１５．０００のフレーク状軟磁性非晶
質合金片を積層した構成とする。Preferably, the soft magnetic amorphous alloy has a structure in which flaky soft magnetic amorphous alloy pieces having a thickness of 5 to 100 μm and an aspect ratio of 10 to 15,000 are laminated.

ンドにて、簡単に固定する電磁波シールドパネルの固定
方法を提供する。Furthermore, the present invention provides a method for fixing electromagnetic shielding panels in which the panels configured as described above are easily fixed together using bolts and pads.
電磁波シールドを施す場合はアルミニウムまたは銅の高
導電材を使用すればかなりシールド率を向上させること
ができるが、ある程度のシールド率であれば、鉄、けい
素鋼Ｖ等の磁性体でも接続が充分であれば可能である。When applying electromagnetic shielding, the shielding rate can be significantly improved by using highly conductive materials such as aluminum or copper, but if the shielding rate is to a certain extent, magnetic materials such as iron and silicon steel V will also suffice for connection. If so, it is possible.
磁気シールドに対しては、アルミニウム、銅では全く効
果はなく、鉄、けい素鋼でも透磁率が低いため不充分で
ある。高透磁率非晶質金属であれば高効率で磁気シール
ドできる。この非晶質金属は、薄帯状であれば幅が狭い
ため、複合化の際に施工性が複雑となるため、非晶質合
金片の積層体が好ましい。For magnetic shielding, aluminum and copper have no effect at all, and even iron and silicon steel are insufficient because of their low magnetic permeability. High magnetic permeability amorphous metals can provide highly efficient magnetic shielding. If this amorphous metal is in the form of a thin strip, its width will be narrow, which will complicate workability when compounding. Therefore, a laminate of amorphous alloy pieces is preferable.
非晶質合金片の厚さを５μｍ未満にすると非晶質合金片
の製造が困難であり、これが１００μｍを越えて厚くな
ると非晶質化が難しくなるのでこの厚さは、５〜１００
μｍとする。特に好ましい厚さ２０〜６０μｍである。If the thickness of the amorphous alloy flake is less than 5 μm, it is difficult to manufacture the amorphous alloy flake, and if it becomes thicker than 100 μm, it becomes difficult to make it amorphous.
Let it be μm. A particularly preferable thickness is 20 to 60 μm.
非晶質合金片のアスペクト比が１０未満では、非晶質合

ましい範囲は５０〜ｉｏ、ｏｏ。If the aspect ratio of the amorphous alloy flake is less than 10, the magnetic permeability of the amorphous alloy flake decreases, and the magnetic shielding properties of the amorphous alloy flake change, making lamination difficult and deteriorating the magnetic shielding property. It becomes like this. On the other hand, if the aspect ratio is
, ooo, handling of the amorphous alloy pieces becomes troublesome and productivity decreases. A particularly preferred range of aspect ratio is 50 to io, oo.
である。It is.

安くなった。(Example 1) Construct a quadrilateral as shown in Fig. 1 with L-shaped angle 3,
Bend the 2.31 thick steel plate 2 on top of it and spot weld it.
A box shape was created. As shown in Fig. 1.2, on top of the iron plate 2, the amorphous alloy flakes laminated sheet 1 as described above is pasted with an adhesive so as to follow the shape, and 600 dragon width x I + 200 crane length x 50 crane height panel. At the center of this panel in the height direction, 5 bolt holes are machined with a pitch of 100 dragons. Using this panel, a shield room with a width of 4.8 m, a length of 6 yn, a length of 2.4 rn, and a height of 2.4 rn was manufactured. After tightening the panels with bolts and nuts 6 in holes 5 that had been previously drilled, welding 8 was performed so that the steel plates 2 were connected to each other, as shown in FIG. Further, as shown in FIG. 4, the corner portions were fixed with bolts 11 using auxiliary angles 10, and then the angles 10 and the steel plate were welded. As a result, this shielded room can reduce the static magnetic field of 5G to below IG, and
It is possible to obtain an attenuation rate of 60 dB or more in the range from 0 KHz to IGHz, making it possible to perform everything from magnetic shielding for static magnetic fields to electromagnetic shielding for high frequency regions, and the construction period is shortened by two-thirds compared to the conventional construction method using lightweight steel frames. , the cost has also become cheaper.

ことができた。The shield room was 468 m wide x 6 m long x 2.4 m high, and the joints between the panels were capped with aluminum auxiliary material 7 so as to weaken both angles 3, and then tightened with 6 bolts. For the corner portions, as shown in FIG. 4, an L-shaped auxiliary angle 1o was used, and after capping with an aluminum auxiliary material 7 if necessary, bolts 11 were tightened. This shielded room can handle 50y of 500+nG magnetic field at 50Hz.

おいて、１００ｄＢ以上の減衰率を得ることができた。This shield room has a variable magnetic field of 100mG to 20mG.
At the same time, it was possible to obtain an attenuation rate of 100 dB or more in IMHz to 100 MHz.
工期も非常に短縮され、３分の２とすることができた。The construction period was also greatly shortened, cutting it by two-thirds.

い。In addition to the above, when creating a shield room when you do not want the magnetic field inside the room to leak to the outside, it is necessary to place an amorphous alloy laminated sheet on the outside, so the panel assembly is carried out in Examples 1 to 3. Since it is the opposite, it is necessary to construct the corner part as shown in Figure 9.10. Moreover, when using auxiliary materials, the construction method shown in FIG. 11.12 may be used.

れる。Next, when constructing an electromagnetic and magnetically shielded room, unlike conventional construction methods in which the frame is framed with lightweight steel or wood, holes are pre-drilled between the bent parts of the panels and bolts are inserted into those parts. Since the connection can be easily made by tightening with a screwdriver and a nand, the construction period is greatly shortened.

ことができる。In addition, when using electromagnetic shielding, especially when the frequency is low, a small space becomes a problem, so it is possible to weld the bent parts of the panels together or to place U-shaped auxiliary materials at the bolt tightening parts. Leakage from the mating portion can be prevented and electrical conductivity can be obtained.
