【発明の属する技術分野】
本発明は、電磁遮蔽材からなる電磁遮蔽層で覆ってビル内空間を外部からの独立した電磁遮蔽空間として構成する電磁遮蔽ビルのリニューアルの窓施工方法に関する。
【0002】
【従来の技術】
今やオフィスビルでは、LANその他の通信回線を使ってそれぞれが独自の通信情報処理システムを構築しているところが多い。このようなシステムが大規模化すると、通信回線の確保が課題になり、ケーブルの配線も複雑に錯綜して、部屋や装置の配置替えの際には、そのための配線変更の作業量が多くなるため、電波を使った無線通信方式の採用も1つの方法として注目されている。
【0003】
ところが、電波を使った無線通信方式を採用する場合には、使用周波数帯域について電波法の規制が問題になる。そこで、このような電波法による規制を受けることなく、自由に使用周波数帯域を選択、設定して独自の無線による通信方式を採用するためには、ビル内の空間を外部から電磁的に遮蔽した電磁遮蔽ビルの構築が不可欠となる。既に出願人は、このような電磁遮蔽ビルに関し、例えば特公平6−99972号公報や特公平6−99973号公報、特公平7−16118号公報、特公平6−76706号公報に、ビルの躯体や外壁の遮蔽構造について提案し、特公平6−99971号公報や特公平6−33699号公報、特公平6−13822号公報に、ビルの出入口の遮蔽構造について、特公平6−63407号公報や特公平5−79790号公報、特公平3−58557号公報に、窓開口部の遮蔽構造について提案している。また、特公平3−62320号公報や特公平3−45972号公報、特公平3−62318号公報、特公平5−34159号公報に、天井や階層別の遮蔽構造について提案している。
【0004】
これらの提案に見られるように、電磁遮蔽ビルは、躯体や壁構造体に電磁遮蔽材を用い、さらに窓や出入口等の開口部にも電磁遮蔽材を用いてビルの外壁に沿って全面を電磁遮蔽材で覆うようにすることにより、ビル内の空間を外部と独立した1つの電磁遮蔽空間として構成することができる。また、ビル内を1つの電磁遮蔽空間としてではなく、各フロア毎に上下の天井や床において電磁遮蔽材で仕切り、或いは各フロアにおいて部屋間の壁を電磁遮蔽材で仕切ることによって、各フロア毎、或いは各部屋毎に独立した複数の電磁遮蔽空間を構成することができる。
【0005】
【発明が解決しようとする課題】
ところで、既設のビルを電磁遮蔽ビルとしてリニューアルしようとする場合には、当然、躯体が電磁遮蔽性能を有していないので、壁や床、天井に、金属メッシュや金属箔、導電性繊維を用いたシート、導電性塗料等の電磁遮蔽材をその内面や内装材との間に貼り合わせることによって実現できる。しかし、窓部は、電磁遮蔽層を有するガラスと取り替えることになると、施工が難しくなりコストも高くなるという問題がある。
【0006】
例えば窓部に電磁遮蔽ガラスを用いる場合、通常考えられているのは、複層タイプであるため、既存建物のサッシ溝幅に入らない場合が多い。加えて上記のような電磁遮蔽ガラスは高価であるという問題もある。
【0007】
【課題を解決するための手段】
本発明は、上記の課題を解決するものであって、窓開口部の電磁遮蔽を簡便に施工することができる電磁遮蔽ビルリニューアルの窓施工方法を提供するものである。
【0008】
そのために本発明は、シール材やバックアップ材を用いて窓のサッシ枠に窓ガラスが装着されている既存のビルに対し電磁遮蔽材からなる電磁遮蔽層を覆ってビル内空間を外部からの独立した電磁遮蔽空間として構成する電磁遮蔽ビルにリニューアルするための窓施工方法であって、
既存の前記窓ガラスの内側のシール材やバックアップ材を除去し、
しかる後既存の前記窓ガラスの内側に電磁遮蔽性能を有するフイルムを貼り合わせ、
既存の前記窓ガラスの内側に貼り合わせたフイルムとサッシ枠との溝部に導電性押縁またはガスケットを嵌め込むことにより、前記窓ガラス及びフイルムをサッシ枠の内側から押さえ固定して
電磁遮蔽ビルにリニューアルするための窓施工を行うこと特徴とする。
【0009】
【発明の実施の形態】
以下、本発明の実施の形態を図面を参照しつつ説明する。
図1は本発明に係るフイルム遮蔽窓構造の電磁遮蔽ビルの実施の形態を示す図であり、1は窓開口部、2は壁、3は天井、4は床を示す。
【0010】
図1において、壁2は、例えば既設の電磁遮蔽性能を有しない躯体の内壁に金属メッシュや金属箔(フイルム)、不織布、その他導電性繊維を用いたシート等を貼ったり、導電性塗料を塗って電磁遮蔽構造にしたもの、或いはこのような電磁遮蔽構造のボードを用いたものである。天井3、床4も、壁2と同様の施工、電磁遮蔽材を貼り合わせたパネルを用いたものである。これに対して、窓開口部1は、窓ガラスの内側に電磁遮蔽性能を有するフイルムを貼り合わせて用い、サッシ溝部のフイルムとの間の施工には、導電性の押縁やガスケットを用いたものである。なお、外側の施工には、通常のシーリング材を用いている。電磁遮蔽性能を有するフイルムとしては、例えば太陽光線反射フイルム、さらにこれと導電性フイルムを組み合わせた複合フイルムを用いることができる。
【0011】
図2は本発明に係るフイルム遮蔽窓構造の断面図であり、11はガラス、12はフイルム、13は押縁、14はシール材、15はバックアップ材、16はサッシ枠、17はセッティングブロックを示す。
【0012】
図2において、ガラス11は、通常のガラスである。したがって、既存のビルでは、既存のガラスをそのまま用いることができる。フイルム12は、例えば電磁遮蔽性能を有する太陽光線反射フイルムであり、ガラス11の内面に貼り合わせる。押縁13は、ガラス11の内面に貼り合わせたフイルム12とサッシ枠16とを電気的に接続するように導電性材料を用いたものであり、導電性ガスケットであってもよい。シール材14、バックアップ材15、セッティングブロック16は、それぞれサッシ枠16にガラス11を装着する場合に通常用いられるものであり、シール材14、バックアップ材15は、ガラス11の外側に用いられる。
【0013】
次に、リニューアルの場合の窓部の施工について説明する。リニューアルの場合には、既存のガラスをそのまま使用する。シール材やバックアップ材を内側だけ除去してからフイルム12をガラス11に貼り合わせる。そして、フイルム12の上からサッシ枠16との溝部に押縁13を嵌め込んで、ガラス11及びフイルム12をサッシ枠16の内側から押さえ固定する。フイルム12は、最近耐久性が向上し、特に太陽光線を遮蔽するもので10年以上にわたり所定の性能を維持するだけの期待が持てるようになっているが、性能が低下して交換する場合には、押縁13を外してフイルム12を剥がし、同様の施工を行えばよい。
【0014】
図3は本発明に係るフイルム遮蔽窓構造の他の実施の形態を示す図であり、太陽光線反射フイルム12に導電性フイルム22を組み合わせて用いた複合フイルムの構造の例である。外側を太陽光線反射フイルム12にして内側に導電性フイルム22を組み合わせて用いると、紫外線などを遮断するためフイルム全体の耐久性が向上すると共に、電磁遮蔽性能を確保することができる。したがって、導電性フイルム22だけを用いた場合に比較して著しく耐久性の向上が見られ、しかも、コストの低減を図ることもできる。
【0015】
なお、本発明は、上記の実施の形態に限定されるものではなく、種々の変形が可能である。例えば上記の実施の形態では、既存の建物をリニューアルする場合に適用して説明したが、新築の建物であっても同様に適用できることはいうまでもない。また、フイルムは、上記太陽光線反射フイルム以外でも、電磁遮蔽性能を有する他のフイルムを用いてもよいし、薄いメッシュ状の導電性材料をフイルムとして用いてもよい。
【0016】
【発明の効果】
以上の説明から明らかなように、本発明によれば、既存のガラスの内側でシール材等を除去し、フイルムを貼り合わせてサッシ枠の溝部に導電性の押縁やガスケットを施工することによって電磁遮蔽層を実現できるので、既存の建物のリニューアルに対応でき、しかも、電磁遮蔽ガラスと交換せずに低コストで簡便に電磁遮蔽窓を施工できる。また、太陽光線反射フイルムに導電性フイルムを組み合わせた複合フイルムの構造にすることにより、従来の電磁遮蔽ガラスより低コストで耐久性の高い所望の電磁遮蔽レベルの窓部を実現できる。

BACKGROUND OF THE INVENTION
The present invention relates to a renewal window construction method for an electromagnetically shielded building, which is covered with an electromagnetic shield layer made of an electromagnetic shield material and constitutes a building interior space as an independent electromagnetic shielded space from the outside.
[0002]
[Prior art]
Many office buildings now have their own communication information processing systems built using LAN and other communication lines. When such a system becomes large-scale, securing communication lines becomes a problem, and the wiring of cables is complicated and complicated, and the amount of work for changing the wiring becomes large when rearranging rooms and devices. Therefore, the adoption of a wireless communication system using radio waves has attracted attention as one method.
[0003]
However, when a radio communication system using radio waves is adopted, regulations of the Radio Law regarding the frequency band used become a problem. Therefore, in order to select and set the use frequency band freely and adopt a unique wireless communication system without being restricted by the Radio Law, the space in the building is electromagnetically shielded from the outside. Construction of electromagnetic shielding building is indispensable. For example, Japanese Patent Publication No. 6-99972, Japanese Patent Publication No. 6-99973, Japanese Patent Publication No. 7-16118, Japanese Patent Publication No. 6-76706, and the like, And the outer wall shielding structure, and Japanese Patent Publication No. 6-99971, Japanese Patent Publication No. 6-33699, Japanese Patent Publication No. 6-13822, and the Japanese Patent Publication No. 6-63407 Japanese Patent Publication No. 5-79790 and Japanese Patent Publication No. 3-58557 propose a shielding structure for a window opening. Further, Japanese Patent Publication No. 3-62320, Japanese Patent Publication No. 3-45972, Japanese Patent Publication No. 3-62318, and Japanese Patent Publication No. 5-34159 have proposed shielding structures according to ceilings and layers.
[0004]
As seen in these proposals, electromagnetic shielding buildings use electromagnetic shielding materials for the frame and wall structure, and also use electromagnetic shielding materials for openings such as windows and doorways to cover the entire surface along the outer wall of the building. By covering with the electromagnetic shielding material, the space in the building can be configured as one electromagnetic shielding space independent from the outside. Also, instead of building the building as a single electromagnetic shielding space, each floor is partitioned by electromagnetic shielding materials on the top and bottom ceilings and floors, or walls between rooms on each floor are separated by electromagnetic shielding materials. Alternatively, a plurality of independent electromagnetic shielding spaces can be configured for each room.
[0005]
[Problems to be solved by the invention]
By the way, when trying to renew an existing building as an electromagnetic shielding building, naturally, the frame does not have electromagnetic shielding performance, so metal mesh, metal foil, or conductive fiber is used for walls, floors, and ceilings. It can be realized by attaching an electromagnetic shielding material such as a sheet or conductive paint between the inner surface and the interior material. However, when the window portion is replaced with glass having an electromagnetic shielding layer, there is a problem that the construction becomes difficult and the cost becomes high.
[0006]
For example, when an electromagnetic shielding glass is used for a window part, since what is usually considered is a multi-layer type, it often does not enter the sash groove width of an existing building. In addition, there is a problem that the electromagnetic shielding glass as described above is expensive.
[0007]
[Means for Solving the Problems]
This invention solves said subject and provides the window construction method of the electromagnetic shielding building renewal which can construct electromagnetic shielding of a window opening part simply.
[0008]
For this purpose, the present invention covers an electromagnetic shielding layer made of an electromagnetic shielding material on an existing building in which a window glass is attached to a window sash frame using a sealing material or a backup material, and the interior space of the building is made independent A window construction method for renewing an electromagnetic shielding building configured as an electromagnetic shielding space,
Remove the sealing material and backup material inside the existing window glass ,
After that, a film having electromagnetic shielding performance is pasted inside the existing window glass,
By fitting the conductive ridge or gasket groove with existing said bonded to the inside of the window glass film and sash frame, fixed to hold the window glass and film from the inside of the sash frame
It is characterized by the construction of windows for renewal to electromagnetic shielding buildings .
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a view showing an embodiment of an electromagnetic shielding building having a film shielding window structure according to the present invention, wherein 1 is a window opening, 2 is a wall, 3 is a ceiling, and 4 is a floor.
[0010]
In FIG. 1, for example, the wall 2 has a metal mesh, a metal foil (film), a nonwoven fabric, a sheet using other conductive fibers, or a conductive paint applied to the inner wall of a casing that does not have electromagnetic shielding performance. Thus, an electromagnetic shielding structure or a board having such an electromagnetic shielding structure is used. The ceiling 3 and the floor 4 are also constructed using the same construction as that of the wall 2 and a panel to which an electromagnetic shielding material is bonded. On the other hand, the window opening 1 uses a film having electromagnetic shielding performance on the inner side of the window glass and uses a conductive ledge or gasket for construction with the sash groove film. It is. In addition, a normal sealing material is used for the outside construction. As a film having electromagnetic shielding performance, for example, a sunlight reflecting film, and a composite film combining this with a conductive film can be used.
[0011]
FIG. 2 is a cross-sectional view of a film shielding window structure according to the present invention, wherein 11 is glass, 12 is a film, 13 is a ledge, 14 is a sealing material, 15 is a backup material, 16 is a sash frame, and 17 is a setting block. .
[0012]
In FIG. 2, glass 11 is normal glass. Therefore, existing glass can be used as it is in an existing building. The film 12 is, for example, a sunlight reflecting film having electromagnetic shielding performance, and is bonded to the inner surface of the glass 11. The pressing edge 13 uses a conductive material so as to electrically connect the film 12 bonded to the inner surface of the glass 11 and the sash frame 16, and may be a conductive gasket. The seal material 14, the backup material 15, and the setting block 16 are each normally used when the glass 11 is attached to the sash frame 16, and the seal material 14 and the backup material 15 are used outside the glass 11.
[0013]
Next, the construction of the window in the case of renewal will be described. In the case of renewal, the existing glass is used as it is. The film 12 is bonded to the glass 11 after removing only the sealing material and the backup material inside. Then, the pressing edge 13 is fitted into the groove portion with the sash frame 16 from above the film 12, and the glass 11 and the film 12 are pressed and fixed from the inside of the sash frame 16. The film 12 has recently been improved in durability and can be expected to maintain a predetermined performance for more than 10 years. May remove the pressing edge 13 and peel off the film 12 and perform the same construction.
[0014]
FIG. 3 is a view showing another embodiment of the film shielding window structure according to the present invention, which is an example of the structure of a composite film in which a conductive film 22 is used in combination with a sunlight reflecting film 12. When the outer side is the solar light reflecting film 12 and the conductive film 22 is used in combination, the ultraviolet ray is cut off, so that the durability of the entire film is improved and the electromagnetic shielding performance can be secured. Therefore, the durability is remarkably improved as compared with the case where only the conductive film 22 is used, and the cost can be reduced.
[0015]
In addition, this invention is not limited to said embodiment, A various deformation | transformation is possible. For example, in the above-described embodiment, the description has been made in the case where an existing building is renewed. However, it goes without saying that the present invention can be similarly applied to a newly built building. Moreover, as the film, other than the solar ray reflecting film, other films having electromagnetic shielding performance may be used, or a thin mesh conductive material may be used as the film.
[0016]
【The invention's effect】
As is clear from the above description, according to the present invention, the sealing material and the like are removed inside the existing glass, the film is attached, and a conductive ledge or gasket is applied to the groove portion of the sash frame. Since the shielding layer can be realized, it is possible to cope with the renewal of an existing building, and it is possible to easily construct an electromagnetic shielding window at low cost without replacing the electromagnetic shielding glass. Moreover, by using a composite film structure in which a conductive film is combined with a sunlight reflecting film, a window portion having a desired electromagnetic shielding level that is lower in cost and higher in durability than conventional electromagnetic shielding glass can be realized.
