Description

本発明は、電磁波をシールド（遮蔽）する電磁波シールドルームに関する。 The present invention relates to an electromagnetic wave shield room that shields electromagnetic waves.

電磁波シールドルームとして、２枚の板材と、その板材間に配した導電性シートから構成され、導電性シートは表面に金属メッキを施した炭素繊維不織布からなり、その不織布の縁部は板材縁より張出させた所定の大きさのシールドパネルを構成し、そのシールドパネルを連結して構成するものが提案されている（例えば、特許文献１参照。）。この電磁波シールドルームでは、シートパネル同士を連結する際、シールドパネルから張出した導電性シートの接合部に接着剤を塗布し、接合部同士を接着させて電気的に接続している。 The electromagnetic wave shield room is composed of two plates and a conductive sheet arranged between the plates. The conductive sheet is made of a carbon fiber non-woven fabric whose surface is metal-plated, and the edge of the non-woven fabric is from the edge of the plate. It has been proposed that a shield panel having a predetermined size overhanging is formed and the shield panels are connected to each other (see, for example, Patent Document 1). In this electromagnetic wave shield room, when the sheet panels are connected to each other, an adhesive is applied to the joint portion of the conductive sheet overhanging from the shield panel, and the joint portions are adhered to each other to be electrically connected.

特開平４−１３０７００号公報Japanese Unexamined Patent Publication No. 4-130700

しかし、上述の特許文献１の電磁波シールドルームでは、シートパネル同士を連結する際、シールドパネルから張出した導電性シートの接合部に接着剤を塗布し、接合部同士を接着剤で接着させているため、接着を行う作業員の熟練度等によっては接合部同士の導電性が劣化し、シールド性能が低下するおそれがある、という問題がある。 However, in the electromagnetic wave shield room of Patent Document 1 described above, when the sheet panels are connected to each other, an adhesive is applied to the joint portion of the conductive sheet overhanging from the shield panel, and the joint portions are adhered to each other with the adhesive. Therefore, there is a problem that the conductivity between the joints deteriorates and the shielding performance may deteriorate depending on the skill level of the worker who performs the bonding.

また、導電性シートの接合部を接着剤により接着するため、電磁波シールドルームを組み立てる際、接着剤が硬化するまで時間がかかると共に、接着のやり直しが困難で、さらには電磁波シールドルームを解体する場合には接着した導電性シートの接合部を切断する必要があり、電磁波シールドルームを解体してシールドパネルを再利用する場合には適さないという問題があった。 In addition, since the joints of the conductive sheets are adhered with an adhesive, when assembling the electromagnetic wave shield room, it takes time for the adhesive to harden, it is difficult to redo the adhesion, and when the electromagnetic wave shield room is disassembled. It is necessary to cut the joint portion of the bonded conductive sheet, and there is a problem that it is not suitable for disassembling the electromagnetic wave shield room and reusing the shield panel.

そこで、本発明はこのような問題点に着目してなされたもので、導電性シートの接合部のシールド性能が低下せず、かつ、組み立てが容易であると共に、シールドパネルの再利用も容易な電磁波シールドルームを提供することを目的とする。 Therefore, the present invention has been made by paying attention to such a problem, and the shielding performance of the joint portion of the conductive sheet is not deteriorated, the assembly is easy, and the shield panel can be easily reused. The purpose is to provide an electromagnetic wave shield room.

前記課題を解決するため、本発明の電磁波シールドルームは、金属パネルの間に断熱材および電磁波シールドシートを挟むと共に、電磁波シールドシートの端部がハミ出し部分としてハミ出るように設けたシールドパネル同士を連結して構築した電磁波シールドルームであって、前記シールドパネル同士の連結部分の室内側にはその連結部分に沿って延びる長尺で細幅の長尺細細凹部が形成され、その長尺細細凹部に各シールドパネルからハミ出した前記電磁波シールドシートのハミ出し部分同士を重ね合わせ丸めたハミ出し部分重合丸め部が挿入されていることを特徴とする。
また、本発明に係る電磁波シールドルームでは、前記長尺細細凹部には、前記ハミ出し部分重合丸め部が挿入された後、室内側から樹脂またはゴム製の押縁材が挿入されていることも特徴とする。 In order to solve the above-mentioned problems, in the electromagnetic wave shield room of the present invention, a heat insulating material and an electromagnetic wave shield sheet are sandwiched between metal panels, and shield panels provided so that the end portion of the electromagnetic wave shield sheet is exposed as a protruding portion. This is an electromagnetic wave shield room constructed by connecting the shield panels, and a long and narrow elongated recess extending along the connecting portion is formed on the indoor side of the connecting portion between the shield panels. The electromagnetic wave shield sheet is characterized in that a superpositioned portion of the electromagnetic wave shield sheet, which is formed by superimposing and rounding the exposed portions of the electromagnetic wave shield sheet, is inserted into the fine recesses.
Further, in the electromagnetic wave shield room according to the present invention, a resin or rubber edging material may be inserted from the indoor side after the squeezed out partially polymerized rounded portion is inserted into the long narrow recess. It is a feature.

本発明の電磁波シールドルームでは、シールドパネル同士の連結部分の室内側にはその連結部分に沿って延びる長尺で細幅の長尺細細凹部が形成され、その長尺細細凹部に各シールドパネルからハミ出した電磁波シールドシートのハミ出し部分同士を重ね合わせ丸めたハミ出し部分重合丸め部が挿入されている。
そのため、電磁波シールドシートのハミ出し部分同士を接着剤で接着しないため、導電性シートの接合部のシールド性能の低下を防止できると共に、電磁波シールドルームを容易に組み立てることができ、また、シールドパネルの再利用も容易である。 In the electromagnetic wave shield room of the present invention, a long and narrow elongated narrow recess extending along the connecting portion is formed on the indoor side of the connecting portion between the shield panels, and each shield is formed in the long thin recess. A polymerized rounded portion is inserted, which is obtained by superimposing and rounding the exposed portions of the electromagnetic wave shield sheet that have been exposed from the panel.
Therefore, since the exposed parts of the electromagnetic wave shield sheet are not adhered to each other with an adhesive, deterioration of the shielding performance of the joint portion of the conductive sheet can be prevented, the electromagnetic wave shield room can be easily assembled, and the shield panel can be assembled. It is easy to reuse.

In addition to the entrance door and the outlet, the electromagnetic wave shield room 1 is provided with a heat exchanger, lighting, an AC distribution board, a noise cut transformer, etc., but these are well-known ones that are not related to the present invention. Therefore, description and illustration will be omitted.

そして、シールドパネル１１を横方向に連結するため、左右の縦板１１ｅ，１１ｆの内、一方の縦板１１ｅには、フック形状のパネル接続用フック１１ｉが設けられている一方、他方の縦板１１ｆには、パネル接続用フック１１ｉが係止するスリット１１ｊ（図３(ａ)参照。）が形成されている。 Then, in order to connect the shield panels 11 in the horizontal direction, one of the left and right vertical plates 11e and 11f is provided with a hook-shaped panel connecting hook 11i, while the other vertical plate is provided. A slit 11j (see FIG. 3A) is formed in the 11f to which the panel connecting hook 11i is locked.

ここで、金属パネル１１ａ，１１ｂとしては、例えば、厚さ０．５ｍｍの鋼板または厚さ０．８ｍｍのアルミ板を使用し、高さは約２４００ｍｍ、幅は９００ｍｍ程度確保して、壁材や天井材、床材となるようにする。 Here, as the metal panels 11a and 11b, for example, a steel plate having a thickness of 0.5 mm or an aluminum plate having a thickness of 0.8 mm is used, and a height of about 2400 mm and a width of about 900 mm are secured to form a wall material or the like. Make it a ceiling material and floor material.

また、金属パネル１１ａ，１１ｂは、平板形状でも良いが、後述する図３〜図８に示すように連結材１１ｃや連結材１１ｄ、縦板１１ｅ，１１ｆがズレずに金属パネル１１ａ，１１ｂ周縁に確実に納まるように折り曲げたり、シールドパネル１１，１１同士の連結箇所の室内側では隙間が発生する段差や凹部を設ける一方、シールドパネル１１，１１同士の連結箇所の室外側では隙間が発生せずに重なるように突出等させて形成している。尚、シールドメッシュ１１ｈが内側に設けられる金属パネル１１ｂは室内側のパネルとなり、シールドメッシュ１１ｈが内側に設けられない金属パネル１１ａは室外側のパネルとなるようにシールドパネル１１を使用する。 Further, the metal panels 11a and 11b may have a flat plate shape, but as shown in FIGS. 3 to 8 described later, the connecting members 11c, the connecting members 11d, and the vertical plates 11e and 11f are not displaced on the periphery of the metal panels 11a and 11b.

＜実施形態の電磁波シールドルーム１の主な効果＞
以上説明したように本発明に係る実施形態の電磁波シールドルーム１では、シールドパネル１１，１１同士の連結箇所では、シールドメッシュ１１ｈのハミ出し部分１１ｈ’を重ね合わせ丸めてハミ出し部分重合丸め部１１ｈ”を形成し、そのハミ出し部分重合丸め部１１ｈ”を図２(ａ)に示す押縁材１２または図２(ｂ)に示す押縁材１２’等によって、シールドパネル１１，１１同士の連結箇所に形成した隙間１１ｋに押し込むことにより連結したシールドパネル１１のシールドメッシュ１１ｈ同士を接続する。 <Main effects of the electromagnetic wave shield room 1 of the embodiment>
As described above, in the electromagnetic wave shield room 1 of the embodiment according to the present invention, at the connection portion between the shield panels 11 and 11, the shaving portion 11h'of the shield mesh 11h is overlapped and rolled, and the shaving part polymerization rounded portion 11h The shield panel 11 and 11 are connected to each other by the edging material 12 shown in FIG. 2 (a) or the edging material 12'shown in FIG. 2 (b). The shield meshes 11h of the shield panels 11 connected by pushing into the formed gap 11k are connected to each other.

そのため、シールドパネル１１，１１同士の隙間１１ｋに押し込まれたハミ出し部分重合丸め部１１ｈ”は、シールドメッシュ１１ｈが２枚重ね以上に幾重にも重なるので、シールドメッシュ１１ｈのハミ出し部分１１ｈ’を接着剤で貼り付ける場合よりも、シールドパネル１１，１１同士の連結箇所の隙間１１ｋから電磁波が漏れることを効果的に防止することができ、電磁波が漏れ易い隙間１１ｋから電磁場が漏れ難くなるので、電磁波シールドルーム１全体の電磁波遮蔽能力を向上させることができる。 Therefore, in the partially polymerized rounded portion 11h of the shield mesh 11h pushed into the gap 11k between the shield panels 11 and 11, the shield mesh 11h overlaps more than two layers, so that the squeezing portion 11h'of the shield mesh 11h is formed. Compared to the case of pasting with an adhesive, it is possible to effectively prevent electromagnetic waves from leaking from the gap 11k at the connecting portion between the shield panels 11 and 11, and the electromagnetic field is less likely to leak from the gap 11k where electromagnetic waves easily leak. The electromagnetic wave shielding ability of the entire electromagnetic wave shielding room 1 can be improved.

特に、シールドメッシュ１１ｈのハミ出し部分１１ｈ’を重ね合わせ丸めてハミ出し部分重合丸め部１１ｈ”をシールドパネル１１，１１同士の連結箇所の隙間１１ｋの奥まで押し込むため、その隙間１１ｋでは、隙間１１ｋの入口からハミ出し部分重合丸め部１１ｈ”まで各シールドパネル１１，１１のシールドメッシュ１１ｈのハミ出し部分１１ｈ’が狭い空間で対向するので、この点でもその隙間１１ｋでの電磁波の遮蔽能力が向上し、電磁波シールドルーム１全体の電磁波遮蔽能力を向上させることができる。 In particular, since the squeeze-out portion 11h'of the shield mesh 11h is overlapped and rolled up, and the squeeze-out partial polymerization rounded portion 11h "is pushed deep into the gap 11k at the connection point between the shield panels 11 and 11, the gap 11k is the gap 11k. Since the humming part 11h'of the shield mesh 11h of each shield panel 11 and 11 faces each other in a narrow space from the entrance of the humming part to the humming part polymerization rounded part 11h ", the electromagnetic wave shielding ability in the gap 11k is improved in this respect as well. However, the electromagnetic wave shielding ability of the entire electromagnetic wave shielding room 1 can be improved.

また、実施形態の電磁波シールドルーム１では、シールドメッシュ１１ｈのハミ出し部分１１ｈ’同士を接着剤で接着せずに重ね合わせた上で丸めて連結するため、シールドメッシュ１１ｈのハミ出し部分１１ｈ’同士が確実に電気的に接続され、電磁波シールドルーム１全体を一枚のシールドメッシュ１１で囲んだ状態とほぼ同じとなり、この点でも電磁波シールドルーム１全体の電磁波遮蔽能力を向上させることができる。 Further, in the electromagnetic wave shield room 1 of the embodiment, since the exposed portions 11h'of the shield mesh 11h are overlapped with each other without being adhered with an adhesive and then rolled and connected, the exposed portions 11h'of the shield mesh 11h are connected to each other. Is reliably electrically connected, and is almost the same as a state in which the entire electromagnetic wave shield room 1 is surrounded by a single shield mesh 11, and in this respect as well, the electromagnetic wave shielding ability of the entire electromagnetic wave shield room 1 can be improved.

また、実施形態の電磁波シールドルーム１では、シールドメッシュ１１ｈのハミ出し部分１１ｈ’同士は重ね合わせて丸めたハミ出し部分重合丸め部１１ｈ”を、図２(ａ)，(ｂ)に示すような押縁材１２，１２’によってシールドパネル１１，１１同士の連結箇所の隙間１１ｋに押し込むだけで、従来技術のように接着剤により接着しないため、電磁波シールドルーム１を容易に組み立てることができると共に、電磁波シールドルーム１を分解も容易となり、シールドパネル１１の再利用も容易である。 Further, in the electromagnetic wave shield room 1 of the embodiment, the “partial polymerization rounded portion 11h” of the shield mesh 11h in which the exposed portions 11h'are overlapped and rounded is as shown in FIGS. 2 (a) and 2 (b). The electromagnetic wave shield room 1 can be easily assembled and the electromagnetic wave can be easily assembled because the ridge members 12 and 12'just push the shield panels 11 and 11 into the gap 11k at the connecting point and do not adhere with an adhesive as in the prior art. The shield chamber 1 can be easily disassembled, and the shield panel 11 can be easily reused.

特に、実施形態の電磁波シールドルーム１では、シールドメッシュ１１ｈのハミ出し部分１１ｈ’を重ね合わせ丸めたハミ出し部分重合丸め部１１ｈ”を図２(ａ)，(ｂ)に示すような押縁材１２，１２’によって、シールドパネル１１，１１同士の連結箇所に形成した隙間１１ｋに押し込むため、ハミ出し部分重合丸め部１１ｈ”を簡単かつ確実に隙間１１ｋの奥まで押し込むことが可能となり、電磁波シールドルーム１全体の電磁波遮蔽能力を確実に向上させることができると共に、電磁波シールドルーム１を容易に組み立てることができる。 In particular, in the electromagnetic wave shield room 1 of the embodiment, the ridge material 12 as shown in FIGS. , 12'pushes into the gap 11k formed at the connection point between the shield panels 11 and 11, so that the partially polymerized rounded portion 11h with a bite can be easily and surely pushed into the gap 11k, and the electromagnetic wave shield room. The electromagnetic wave shielding ability of the entire 1 can be surely improved, and the electromagnetic wave shielding room 1 can be easily assembled.

また、実施形態の電磁波シールドルーム１では、従来技術とは異なり、シールドメッシュ１１ｈのハミ出し部分１１ｈ’同士を接着剤で接着せず、重ね合わせた上で丸めて押縁材１２，１２’によってシールドパネル１１，１１同士の連結箇所の隙間１１ｋに押し込むだけであるため、シールドメッシュ１１ｈのハミ出し部分１１ｈ’の重ね処理や丸め処理等が上手くいかなかった場合にはやり直しも容易であり、この点でも電磁波シールドルーム１全体の電磁波遮蔽能力を向上させることができる。 Further, in the electromagnetic wave shield room 1 of the embodiment, unlike the conventional technique, the exposed portions 11h'of the shield mesh 11h are not adhered to each other with an adhesive, but are overlapped and rolled up and shielded by the edging materials 12, 12'. Since the panels 11 and 11 are simply pushed into the gap 11k at the connection point, it is easy to redo if the overlapping process or the rounding process of the squeezed portion 11h'of the shield mesh 11h does not go well. However, the electromagnetic wave shielding ability of the entire electromagnetic wave shielding room 1 can be improved.
