Description

複層ガラスDouble glazing
　本発明は、複層ガラスに関する。 The present invention relates to a multilayer glass.
　フレームに取り付けられる既存のガラス板に対し、枠状のスペーサを介して新規のガラス板を貼り付ける、複層ガラスの製造方法が提案されている（例えば特許文献１参照）。新規のガラス板は、既存のガラス板の室内側に配設される。既存のガラス板を複層ガラスの一部として利用することにより、施工費の削減、施工期間の短縮などが可能である。また、既存のガラス板や既存のフレームがそのまま再利用でき、資源の無駄が削減できる。 A method for producing a double-glazed glass in which a new glass plate is attached to an existing glass plate attached to a frame via a frame-shaped spacer has been proposed (for example, see Patent Document 1). The new glass plate is disposed on the indoor side of the existing glass plate. By using an existing glass plate as a part of the double glazing, it is possible to reduce the construction cost and the construction period. In addition, existing glass plates and existing frames can be reused as they are, and resource waste can be reduced.

　フレームの内周には固定溝が形成されており、固定溝の内部に既存のガラス板の端部が固定されている。一方、新規のガラス板は、固定溝の外部に配設されており、固定溝の内部に固定されていない。そのため、既存のガラス板が割れたときに、新規のガラス板のバランスが崩れ、新規のガラス板が室外側に脱落する虞があった。 The fixed groove is formed in the inner periphery of the frame, and the end of the existing glass plate is fixed inside the fixed groove. On the other hand, the new glass plate is disposed outside the fixed groove and is not fixed inside the fixed groove. Therefore, when the existing glass plate is broken, the balance of the new glass plate is lost, and the new glass plate may drop out to the outdoor side.

　第１ガラス板１１は、フレームに固定される既存のガラス板である。第１ガラス板１１の端部は、フレームの内周に形成される固定溝３１、３２の内部に固定部材３３、３４などで固定される。第１ガラス板１１は、未強化ガラスまたは強化ガラスなどである。第１ガラス板１１は、第２ガラス板１２よりも室外側に配設されるため、強化ガラスであることが好ましい。強化ガラスは、熱強化ガラス、化学強化ガラスのいずれでもよい。 The first glass plate 11 is an existing glass plate fixed to the frame. The edge part of the 1st glass plate 11 is fixed by the fixing members 33 and 34 etc. inside the fixing grooves 31 and 32 formed in the inner periphery of a flame | frame. The first glass plate 11 is untempered glass or tempered glass. Since the 1st glass plate 11 is arrange | positioned in the outdoor side rather than the 2nd glass plate 12, it is preferable that it is a tempered glass. The tempered glass may be either heat tempered glass or chemically tempered glass.
　第２ガラス板１２は、第１ガラス板１１を基準として室内側に配設される新規のガラス板である。第２ガラス板１２は、固定溝３１、３２の外部に配設されており、固定溝３１、３２の内部に固定されていない。第２ガラス板１２は、第１ガラス板１１と同様に、未強化ガラスまたは強化ガラスなどである。 The second glass plate 12 is a new glass plate disposed on the indoor side with respect to the first glass plate 11. The second glass plate 12 is disposed outside the fixed grooves 31 and 32 and is not fixed inside the fixed grooves 31 and 32. Similar to the first glass plate 11, the second glass plate 12 is untempered glass or tempered glass.
　スペーサ１３は、第１ガラス板１１と第２ガラス板１２との間隔を保つ。スペーサ１３は、枠状に形成され、密閉空間１６を取り囲む。スペーサ１３は、中空部を有する。この中空部と密閉空間１６とは連通されており、中空部には乾燥剤が充填される。密閉空間１６が乾燥できる。 The spacer 13 keeps the distance between the first glass plate 11 and the second glass plate 12. The spacer 13 is formed in a frame shape and surrounds the sealed space 16. The spacer 13 has a hollow part. The hollow portion and the sealed space 16 are communicated with each other, and the hollow portion is filled with a desiccant. The sealed space 16 can be dried.
　１次シール１４は、第１ガラス板１１とスペーサ１３との間に配設され、その間を封止すると共に、その間を接着する。また、１次シール１４は、スペーサ１３と第２ガラス板１２との間に配設され、その間を封止すると共に、その間を接着する。 The primary seal 14 is disposed between the first glass plate 11 and the spacer 13, and seals between them and bonds them together. Further, the primary seal 14 is disposed between the spacer 13 and the second glass plate 12, and seals between them and bonds them therebetween.
　２次シール１５は、スペーサ１３を取り囲むように配設され、第１ガラス板１１と第２ガラス板１２との間を封止すると共に、その間を接着する。２次シール１５が第１ガラス板１１と第２ガラス板１２とを接着できるように、スペーサ１３は第１ガラス板１１および第２ガラス板１２よりも小さく形成される。 The secondary seal 15 is disposed so as to surround the spacer 13, and seals between the first glass plate 11 and the second glass plate 12 and adheres between them. The spacer 13 is formed smaller than the first glass plate 11 and the second glass plate 12 so that the secondary seal 15 can bond the first glass plate 11 and the second glass plate 12.
　密閉空間１６は、断熱層を形成する。密閉空間１６には、乾燥空気や不活性ガスが封入される。密閉空間１６の気圧は、大気圧と同じでもよいし、大気圧よりも小さくてもよい。密閉空間１６は、真空とされてもよい。この場合、密閉空間１６の内部には、第１ガラス板１１と第２ガラス板１２との間隔を保つピラーが設けられてもよい。 The sealed space 16 forms a heat insulating layer. The sealed space 16 is filled with dry air or inert gas. The air pressure in the sealed space 16 may be the same as the atmospheric pressure, or may be smaller than the atmospheric pressure. The sealed space 16 may be evacuated. In this case, a pillar that keeps the distance between the first glass plate 11 and the second glass plate 12 may be provided inside the sealed space 16.
　Ｌｏｗ－Ｅ膜１７は、放射伝熱を抑制することで、熱の通過を制限する。Ｌｏｗ－Ｅ膜１７は、例えば密閉空間１６を挟んで対向する２枚のガラス板のうち、例えば室内側のガラス板（図１では第２ガラス板１２）の対向面に形成される。 The Low-E film 17 restricts the passage of heat by suppressing radiant heat transfer. The Low-E film 17 is formed, for example, on the facing surface of the indoor glass plate (the second glass plate 12 in FIG. 1) among the two glass plates facing each other with the sealed space 16 in between.
　Ｌｏｗ－Ｅ膜１７は、一般的なものであってよく、例えば、透明誘電体膜、赤外線反射膜、および透明誘電体膜をこの順で含む積層膜であってよい。透明誘電体膜としては、金属酸化物や金属窒化物が代表的である。金属酸化物としては、酸化亜鉛や酸化スズが代表的である。赤外線反射膜としては、金属膜が代表的である。金属膜としては、銀（Ａｇ）が代表的である。ここで、赤外線反射膜は、透明誘電体膜同士の間に、１層以上形成されてよい。 The Low-E film 17 may be a general film, for example, a laminated film including a transparent dielectric film, an infrared reflective film, and a transparent dielectric film in this order. Typical examples of the transparent dielectric film include metal oxides and metal nitrides. Typical metal oxides include zinc oxide and tin oxide. A typical example of the infrared reflecting film is a metal film. A typical metal film is silver (Ag). Here, one or more infrared reflective films may be formed between the transparent dielectric films.
　Ｌｏｗ－Ｅ膜１７は、密閉空間１６に収容されてよく、密閉空間１６からはみ出さなくてよい。密閉空間１６は大気と隔離されているため、大気中の水分とＬｏｗ－Ｅ膜１７との接触が防止でき、Ｌｏｗ－Ｅ膜１７の劣化が制限できる。 The Low-E film 17 may be accommodated in the sealed space 16 and may not protrude from the sealed space 16. Since the sealed space 16 is isolated from the atmosphere, contact between moisture in the atmosphere and the Low-E film 17 can be prevented, and deterioration of the Low-E film 17 can be limited.
　尚、Ｌｏｗ－Ｅ膜１７は、耐湿性に優れる場合、図８に示すように密閉空間１６からはみ出してもよい。Ｌｏｗ－Ｅ膜１７は、例えば第２ガラス板１２における第１ガラス板１１との対向面の全面に形成されてもよく、トリミングされていなくてもよい。 Note that the Low-E film 17 may protrude from the sealed space 16 as shown in FIG. For example, the Low-E film 17 may be formed on the entire surface of the second glass plate 12 facing the first glass plate 11 or may not be trimmed.
　室内側脱落防止具１８は、第１ガラス板１１が割れる場合に第２ガラス板１２の室内側への脱落を防止する。よって、二次的な損害を低減することができる。この効果は、第１ガラス板１１が強化ガラスである場合に顕著である。強化ガラスは、全体的に粒状に割れるため、割れた場合に第２ガラス板１２を支えきれないからである。 The indoor side drop prevention tool 18 prevents the second glass plate 12 from falling into the indoor side when the first glass plate 11 breaks. Therefore, secondary damage can be reduced. This effect is significant when the first glass plate 11 is tempered glass. This is because the tempered glass is broken into granular shapes as a whole, so that the second glass plate 12 cannot be supported when broken.
　室内側脱落防止具１８は、第１ガラス板１１が割れる前から第２ガラス板１２を室内側から押さえており、第１ガラス板１１が割れた後に第２ガラス板１２を室内側から押さえ続ける。第２ガラス板１２の室内側へのズレがほとんどない。 The indoor side drop prevention tool 18 holds the second glass plate 12 from the indoor side before the first glass plate 11 breaks, and continues to hold the second glass plate 12 from the indoor side after the first glass plate 11 is broken. . There is almost no displacement of the second glass plate 12 to the indoor side.
　室内側脱落防止具１８は、上側横部材２１に形成される固定溝３１の内部に固定部材３３などで固定されてよく、例えば固定溝３１の室内側の側面に固定されてよい。第２ガラス板１２が室内側に脱落しようとして室内側脱落防止具１８を室内側に押すとき、上側横部材２１が室内側脱落防止具１８を室外側に押し返すことができる。 The indoor side drop prevention tool 18 may be fixed to the inside of the fixing groove 31 formed in the upper lateral member 21 with a fixing member 33 or the like, and may be fixed to the side surface of the fixing groove 31 on the indoor side, for example. When the second glass plate 12 tries to drop out indoors and pushes the indoor side drop prevention tool 18 toward the indoor side, the upper lateral member 21 can push the indoor side drop prevention tool 18 back to the outdoor side.
　室内側脱落防止具１８は、例えばＺ字状に形成され、固定溝３１の室内側の側面に固定される第１鉛直部１８ａと、第２ガラス板１２の室内側の面と接触する第２鉛直部１８ｂと、第１鉛直部１８ａと第２鉛直部１８ｂとを接続する水平部１８ｃとで構成される。 The indoor side fall-off prevention tool 18 is formed in, for example, a Z-shape, and is in contact with the first vertical portion 18 a fixed to the indoor side surface of the fixing groove 31 and the indoor side surface of the second glass plate 12. It is comprised by the vertical part 18b and the horizontal part 18c which connects the 1st vertical part 18a and the 2nd vertical part 18b.
　一方、室外側脱落防止具１９は、第１ガラス板１１が割れる場合に第２ガラス板１２の室外側への脱落を防止する。よって、二次的な損害を低減することができる。この効果は、第１ガラス板１１が強化ガラスである場合に顕著である。強化ガラスは、全体的に粒状に割れるため、割れた場合に第２ガラス板１２を支えきれないからである。 On the other hand, the outdoor dropout prevention tool 19 prevents the second glass plate 12 from dropping out to the outdoor side when the first glass plate 11 breaks. Therefore, secondary damage can be reduced. This effect is significant when the first glass plate 11 is tempered glass. This is because the tempered glass is broken into granular shapes as a whole, so that the second glass plate 12 cannot be supported when broken.
　室外側脱落防止具１９は、第１ガラス板１１が割れる前から第２ガラス板１２を室外側から押さえており、第１ガラス板１１が割れた後に第２ガラス板１２を室外側から押さえ続ける。第２ガラス板１２の室外側へのズレがほとんどない。 The outdoor drop-off prevention tool 19 holds the second glass plate 12 from the outdoor side before the first glass plate 11 breaks, and continues to hold the second glass plate 12 from the outdoor side after the first glass plate 11 is broken. . There is almost no deviation of the second glass plate 12 to the outdoor side.
　室外側脱落防止具１９は、上側横部材２１の外周面に固定されてよい。ここで、上側横部材２１の外周面とは、上側横部材２１の横断面視における上側横部材２１の外周面を意味する。室外側脱落防止具１９は、例えば上側横部材２１の室内側の面に固定されてよい。第２ガラス板１２が室外側に脱落しようとして室外側脱落防止具１９を室外側に押すとき、上側横部材２１が室外側脱落防止具１９を室内側に押し返すことができる。 The outdoor dropout prevention tool 19 may be fixed to the outer peripheral surface of the upper lateral member 21. Here, the outer peripheral surface of the upper lateral member 21 means the outer peripheral surface of the upper lateral member 21 in a cross-sectional view of the upper lateral member 21. The outdoor side fall-off prevention tool 19 may be fixed to, for example, the indoor side surface of the upper lateral member 21. When the second glass plate 12 pushes the outdoor fall-off prevention tool 19 to the outdoor side in an attempt to drop off the outdoor side, the upper lateral member 21 can push the outdoor fall-off prevention tool 19 back to the indoor side.
　室外側脱落防止具１９は、例えばＺ字状に形成され、上側横部材２１の室内側の面に固定される第１鉛直部１９ａと、第２ガラス板１２の室外側の面と接触する第２鉛直部１９ｂと、第１鉛直部１９ａと第２鉛直部１９ｂとを接続する水平部１９ｃとで構成される。 The outdoor fall-off prevention tool 19 is formed in, for example, a Z-shape, and the first vertical portion 19a fixed to the indoor side surface of the upper lateral member 21 and the outdoor side surface of the second glass plate 12 are in contact with each other. 2 vertical portions 19b, and a horizontal portion 19c connecting the first vertical portion 19a and the second vertical portion 19b.
　尚、本実施形態では、室内側脱落防止具１８と、室外側脱落防止具１９とが別々に形成されるが、一体に形成されてもよい。また、室内側脱落防止具１８や室外側脱落防止具１９は、フレームの何処に取り付けられてもよく、下側横部材や左側縦部材、右側縦部材などに取り付けられてもよい。さらに、室内側脱落防止具１８や室外側脱落防止具１９は、複数でもよい。他の実施形態において同様である。 In addition, in this embodiment, although the indoor side drop prevention tool 18 and the outdoor side drop prevention tool 19 are formed separately, you may form integrally. Further, the indoor side drop prevention tool 18 and the outdoor side fall prevention tool 19 may be attached anywhere on the frame, and may be attached to a lower horizontal member, a left vertical member, a right vertical member, or the like. Furthermore, the indoor side fall prevention tool 18 and the outdoor side fall prevention tool 19 may be plural. The same applies to other embodiments.

　複層ガラス１０Ｄは、フレーム２０Ｄに取り付けられる。フレーム２０Ｄは、上側横部材２１Ｄと、下側横部材２２Ｄと、左側縦部材２３Ｄと、右側縦部材２４Ｄとで構成される。 Multi-layer glass 10D is attached to frame 20D. The frame 20D includes an upper horizontal member 21D, a lower horizontal member 22D, a left vertical member 23D, and a right vertical member 24D.
　セッティングブロック４０Ｄは、左側縦部材２３Ｄ、右側縦部材２４Ｄに取り付けられ、下側横部材２２Ｄから浮かして取り付けられる。図１などに示す第２ガラス板１２の重みがセッティングブロック４０Ｄを介して下側横部材２２Ｄに作用せず、下側横部材２２Ｄの撓み変形が抑制できる。 The setting block 40D is attached to the left vertical member 23D and the right vertical member 24D, and is attached to the lower horizontal member 22D. The weight of the second glass plate 12 shown in FIG. 1 or the like does not act on the lower lateral member 22D via the setting block 40D, and the bending deformation of the lower lateral member 22D can be suppressed.
　左側縦部材２３Ｄおよび右側縦部材２４Ｄは、下側横部材２２Ｄとは異なり、水平方向ではなく、上下方向に平行とされる。そのため、左側縦部材２３Ｄおよび右側縦部材２４Ｄは、下側横部材２２Ｄよりも、重力に対する耐久性に優れており、ほとんど変形しない。 Unlike the lower horizontal member 22D, the left vertical member 23D and the right vertical member 24D are not parallel to the horizontal direction but are parallel to the vertical direction. Therefore, the left vertical member 23D and the right vertical member 24D are more excellent in durability against gravity than the lower horizontal member 22D, and hardly deform.
　以上、複層ガラスの実施形態などについて説明したが、本発明は上記実施形態などに限定されず、特許請求の範囲に記載された本発明の要旨の範囲内において、種々の変形、改良が可能である。 As mentioned above, although embodiment of the multilayer glass etc. was demonstrated, this invention is not limited to the said embodiment etc., Various deformation | transformation and improvement are possible within the range of the summary of this invention described in the claim. It is.
