本発明は、サツシ窓枠と電磁遮蔽部材を使用した窓ガラ
スにより構成した電磁遮蔽窓の接地方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method of grounding an electromagnetic shielding window constituted by a window glass using a sash window frame and an electromagnetic shielding member.
近代的なオフィスビルの代表としてインテリジェントビ
ルが挙げられる。インテリジェントビルでは、複合電子
交換機やコンピュータ等の精報通信設備を共同利用し、
ビル内や外部との情報通信を行っている。この情報通信
では、光ファイバー・ケーブルや同軸ケーブルを利用し
たデータバイウェイ方式による情報ネットワークが検討
され、提案されている。Intelligent buildings are representative of modern office buildings. Intelligent buildings share information communication equipment such as complex electronic exchanges and computers,
It communicates information within the building and with the outside world. In this field of information communication, data-byway information networks using optical fiber cables and coaxial cables have been studied and proposed.
しかし、光ファイバー・ケーブルや同軸ケーブルを利用
したデータハイウェイ方式では、光ファイバー・ケーブ

で張りめぐらさなければならず、工費や工期などがケー
ブル敷設のために余分にかかることになる。However, with the data highway method that uses optical fiber cables and coaxial cables, the optical fiber cables and coaxial cables must be stretched to every corner of an intelligent building, which requires extra labor costs and construction time to lay the cables. It will take a while.
ビル内の情報通信に電波を使えばケーブル敷設の必要は
ないが、この場合、一方では、外部へノイズ電波を放出
することから、一定範囲の周波数では電波法上の規制を

部のテレビ中間周波、ワイヤレスマイクの電波等により
システムが誤動作するという問題が生じる。If radio waves are used for information communication within a building, there is no need to lay cables, but in this case, on the other hand, noise radio waves are emitted to the outside, so frequencies within a certain range are subject to regulations under the Radio Law. On the other hand, there is a problem in that the system malfunctions due to external radio waves, internal television intermediate frequency waves, radio waves from wireless microphones, and the like.
つまり、ビル内の無線通信では、自ビルにおいては相互

ユニティ−（外部の電磁波ノイズによって機器が障害を
受ける）という用語を生み、それぞれの技術開発も進め
られている。In other words, wireless communication within a building requires technology that does not introduce electromagnetic noise into the building to prevent mutual interference, and conversely, does not emit electromagnetic waves so as not to affect other buildings. Therefore, technology that does not emit or inject radio waves is required, and those that do not emit radio waves have EMI
(Electro-magnetic interference alliance), and for those that do not transmit radio waves, the term immunity (equipment is damaged by external electromagnetic noise), and each technology is being developed.

になってきた。Additionally, technology that prevents electromagnetic waves from emitting or entering is also required at Combicoater centers, hospitals, and AV conference rooms that handle precision electronic equipment. In particular, recently it has been discovered that radio waves emitted from computers and displays can be easily detected using relatively simple equipment, so the eavesdropping of radio waves leaking from electronic devices that handle information, such as combi coaters, has become a problem. It's here.
その他、外部のノイズ源としては、電車や高圧線、車両

Become.
上記のように電磁遮蔽ビルの需要は様々なところにある

部分の負担を軽減するために、シールドルームに窓を設
けず密室構造にする場合がある。また、仮に窓を設けた
場合にも放送局用の特殊ガラス（合わせガラス）を入れ
たり、或いはシャッターを取り付けることによって窓開
口部の電磁遮蔽性能を確保することもある。As mentioned above, there is demand for electromagnetic shielding buildings in various places, but in the past, when constructing an electromagnetic shielding building, ensuring electromagnetic shielding performance at the openings was troublesome, so we reduced the burden of this part. In order to do this, the shield room may not have a window and be constructed as a closed room. Furthermore, even if a window is provided, the electromagnetic shielding performance of the window opening may be ensured by inserting special glass for broadcasting stations (laminated glass) or by attaching a shutter.

遮蔽を行うようにしている。The applicant has already filed an application for an intelligent building that uses electromagnetic shielding members to construct the frame and openings such as windows and doorways, making the entire building an electromagnetic shielding structure that enables communication within the building using radio waves. are doing. In this intelligent building, electromagnetic waves are shielded throughout the building by using mesh-filled glass or glass covered with conductive film for the windows and entrances and exits of the building.

た。By the way, when imparting electromagnetic shielding performance to the glass window opening as described above, a member having electromagnetic shielding performance, such as a cloth-like material woven from fine wires (mesh), is sandwiched between two pieces of glass. Alternatively, an electromagnetic shielding layer is formed by attaching a metal film having a certain thickness to the glass surface. In order to improve the electromagnetic shielding performance of window openings using such glass, generally, for example, the electromagnetic shielding layer is made thicker to increase the electromagnetic shielding performance of the window glass, and the electromagnetic shielding material used in the window glass is This is to ensure grounding. In other words, the goal is to efficiently release the electromagnetic wave energy captured by the electromagnetic shielding layer to the ground without re-radiating it. Therefore, conventional grounding methods have attempted to ensure complete grounding by electrically connecting everything.

すという問題がある。For example, when using a sash window frame as a window frame, when filling a conductive caulking material between the electromagnetic shielding layer of the window glass and the sash window frame, the alumite finish coating (surface protection film) on the sash surface is applied. -8B is peeled off and electrically connected. Peeling off the surface protective film of the sash in this way not only takes time and effort, but also poses a problem of deteriorating the weather resistance of the sash.

It is characterized by being connected.

ことができる。In the method of grounding an electromagnetic shielding window of the present invention, the electromagnetic shielding member of the window glass is grounded to the window frame through the conductive caulking material and the coating on the surface of the window frame. A capacitor can be formed in the region to impedance ground. Therefore, the electromagnetic shielding layer of the window glass can be grounded through the sash window frame in a high frequency range without peeling off the surface protective coating of the sash.

。In Fig. 1, wire glass 1.2 is so-called wired glass containing mesh wires 3 to 6, and each is commercially available as a general-purpose product and is used as window glass for electromagnetic shielding windows. . If the mesh pitch of these wire glasses 1 and 2 is shifted by half a frame to form a two-panel glass window, electromagnetic shielding performance can be improved.

接地とすることができる。In addition, if only glass with electromagnetic shielding performance is used,
Radio waves enter through the gaps in the glazing around the four sides of the glass, reducing the electromagnetic shielding performance of the window as a whole. Therefore, for example, a conductive tape 9 such as a copper foil tape is applied around the four edges of the end, and the conductive tape 9 is fitted into the sash window frame 10 using a conductive sealing material 7 and a setting block 8 made of conductive rubber. , a conductive sealant 7, a setting block 8, etc. through the wire glass 1.2.
The mesh wires 3 to 6 and the sash window frame 10 are electrically integrated. Therefore, conventionally, Satsushi window frame IO
However, in the present invention, this surface protective coating is not peeled off and the sash window frame 10 is connected to the sash window frame 10 through the surface protective coating. It is characterized by making connections. In this way, several MH
In the high frequency region above z, the surface protective coating can be replaced with a small capacitance capacitor and resistor, and impedance grounding can be achieved.

, can be attenuated by absorption and transmission to the sash window frame 10 through the setting block 8. Note that the conductive tape 9 may be a conductive paint.
次に、本発明が適用される電磁遮蔽窓の種々の変形例を
説明する。Next, various modifications of the electromagnetic shielding window to which the present invention is applied will be explained.
第２図はワイヤーガラスとしてクロスワイヤーガラスを

シワイヤーガラスを使用した例を示す図である。FIG. 2 is a diagram showing an example in which cross wire glass is used as the wire glass, and FIG. 3 is a diagram showing an example in which caltrop wire glass is used as the wire glass.
第２図（ａ）に示すように１３ｍｍの間隔でｘＹ方向に
配列したメッシュ筋ワイヤーに対して、同図ら）に示す
ようにＸＹ力方向それぞれ半コマずつずらして重ねると
、同図（Ｃ）に示すようにメッシュ筋ワイヤーの間隔が
半分の６．５ｍｍとなり、電磁遮蔽性能を高めることが

をとると電磁遮蔽層間の反射、吸収、共振等により電磁
遮蔽効果を上げることができ、この距離Ｘを電磁遮蔽層
の特性や周波数に応じて変えることによって、その効果
をさらに高めることができる。As shown in Figure 2 (a), mesh wires arranged in the x and Y directions at intervals of 13 mm are overlapped by a half frame in each of the X and Y force directions as shown in Figure 2 (C). As shown in Figure 2, the spacing between the mesh wires is halved to 6.5 mm, improving electromagnetic shielding performance. Moreover, according to the results of experiments, it was found that the electromagnetic shielding effect was higher than when one sheet with a spacing of 6.5 mm was used. That is, the distance X on the cross section shown in FIG.
When this distance is set, the electromagnetic shielding effect can be increased due to reflection, absorption, resonance, etc. between the electromagnetic shielding layers, and by changing this distance X according to the characteristics and frequency of the electromagnetic shielding layer, the effect can be further enhanced.
また、第３図に示すようにメッシュ筋ワイヤーが斜め方

かも９ｍｍ間隔の１枚のヒシワイヤーガラスよりも高い
電磁遮蔽性能を確保することができる。The same applies to the case of using a caltrop wire glass in which the mesh wires cross diagonally as shown in FIG. In other words, if the pieces of calcined wire glass shown in (a) of the same figure are stacked with a shift of half the mesh wire pitch, the 18 mm spacing becomes 9 mm, and the electromagnetic resistance is higher than that of a single piece of calcined wire glass with a 9 mm spacing. Shielding performance can be ensured.

性能を高めることができる。In the example shown in FIG. 4(a), the electromagnetic shielding layers 11 and 13 are arranged so as to sandwich the glass 12 from both sides, so that they are separated by the thickness of the glass 12.
Further, a glass 14 is laminated on the electromagnetic shielding layer 13 via an interlayer film or an adhesive layer (not shown), and the glass 1
2.14, the electromagnetic shielding layer 13 is sandwiched therebetween. By doing this, the electromagnetic shielding layer 1
1 and 13 are separated by at least the thickness of the glass 12, and the electromagnetic waves transmitted through one electromagnetic shielding layer are attenuated by absorption/reflection between the electromagnetic shielding layers 11 and 13. Electromagnetic shielding performance can be further improved than in the case of using only an electromagnetic shielding layer.

, a cross section of a laminated glass structure having glasses 12 and 14 and a laminated interlayer film or an adhesive layer as required, and the example shown in FIG.

It is a multi-layer transparent body type in which an electromagnetic shielding layer 20.23 is provided on the inner surface of 9.24. Therefore, in this example, the distance between the electromagnetic shielding layers 20 and 23 can be set by the sealing member 21 regardless of the thickness of the glass 19, 24.

It is possible to improve the electromagnetic shielding performance of the window opening while maintaining the weather resistance of the window. In addition, by simply fitting the window glass using conductive caulking material, back-up material, etc., there is no need to peel off the surface protective coating of the sash, which reduces the number of man-hours, reduces construction costs, and shortens the construction period. It is possible to shorten the time.
