Description

本開示は、複層ガラスに関する。 The present disclosure relates to double glazing.

従来、断熱性や防音性を向上させる観点から、建物の開口部に配置されるガラス窓として複層ガラスが用いられている。複層ガラスは、例えば、少なくとも２枚のガラス板とスペーサとを有する。スペーサは２枚のガラス板間の周縁部に配置され、２枚のガラス板を隔置する。スペーサとガラス板との間には、封着材が配置される。これによって、ガラス板で挟まれる中空層が封止され、複層ガラスが構成される。 2. Description of the Related Art Conventionally, from the viewpoint of improving heat insulation and soundproofing properties, double glazing has been used as glass windows arranged at openings of buildings. Double glazing has, for example, at least two glass panes and spacers. A spacer is disposed peripherally between the two glass plates to space the two glass plates apart. A sealing material is arranged between the spacer and the glass plate. As a result, the hollow layers sandwiched between the glass plates are sealed to form double glazing.

複層ガラスを用いて引き違い窓等の建具を製造する場合、矩形に枠組みされた框体に複層ガラスを嵌め込むことで、建具を製造することが一般的である。これによって、建具としての十分な強度が得られる。一方、複層ガラス自体に形状維持性及び長期耐久性を付与する技術として、ガラス板同士の間隙に、従来のスペーサに加え、樹脂スペーサや金属スペーサを配置する技術が開示されている（例えば、特許文献１参照）。 2. Description of the Related Art When manufacturing a fitting such as a double sliding window using double glazing, it is common to manufacture the fitting by fitting the double glazing into a rectangular frame. By this, sufficient strength as fittings can be obtained. On the other hand, as a technique for imparting shape retention property and long-term durability to the double glazing itself, a technique for arranging a resin spacer or a metal spacer in addition to the conventional spacer in the gap between the glass plates has been disclosed (for example, See Patent Document 1).

特開２００６－２７３７０５号公報JP 2006-273705 A

意匠性向上の観点から、複層ガラスの強度を向上させ、框体のガラス表面への掛かり代を極力小さく、もしくは框体を有さずに建具を構成できることができれば好ましい。しかし、上記目的を達成するため、特許文献１に開示されているように樹脂スペーサを単に配置する場合、建具の十分な強度が得られない。一方、金属スペーサを配置する場合、建具の断熱性が低下するという課題があった。 From the viewpoint of improving the design, it is preferable to improve the strength of the double glazing and to minimize the amount of engagement of the frame with the glass surface, or to form fittings without a frame. However, when resin spacers are simply arranged as disclosed in Patent Document 1 in order to achieve the above object, sufficient strength of fittings cannot be obtained. On the other hand, when arranging a metal spacer, there was a problem that the heat insulating property of fittings deteriorated.

本開示は、上記に鑑みてなされたものであり、框体を小さくできる、もしくは框体を有さずに建具を構成できる強度を有し、かつ断熱性を確保できる複層ガラスを提供することを目的とする。 The present disclosure has been made in view of the above, and provides a double glazing that can reduce the size of the frame or has the strength to configure fittings without a frame and that can ensure heat insulation. With the goal.

本開示は、少なくとも２枚のガラス板がスペーサを介して隔置され、前記ガラス板同士の間隙に中空層が形成された複層ガラスにおいて、前記ガラス板同士の間隙の周縁部、かつ前記スペーサよりも前記ガラス板の端縁側もしくは内周側に、補強部材が配置され、前記補強部材は、前記ガラス板以上の弾性強度を有する繊維強化プラスチックにより構成される、複層ガラスに関する。 The present disclosure relates to a multi-layer glass in which at least two glass plates are spaced apart via a spacer and a hollow layer is formed in the gap between the glass plates, wherein the peripheral portion of the gap between the glass plates and the spacer A reinforcing member is arranged on the edge side or the inner peripheral side of the glass plate, and the reinforcing member is made of fiber reinforced plastic having an elastic strength equal to or greater than that of the glass plate.

《第１実施形態》
本実施形態に係る複層ガラス１は、複数のガラス板であるガラス板２１、ガラス板２２、及びガラス板２３と、補強部材３と、スペーサ４１及びスペーサ４２と、フィルム５と、を有する。以下の説明では、Ｘ方向とは、複層ガラス１の厚さ方向を示し、Ｙ方向とは、Ｘ方向に直交する複層ガラス１の幅方向を示し、Ｚ方向とは、Ｘ方向及びＹ方向に直交する複層ガラス１の高さ方向を示す。 <<1st Embodiment>>
The multi-layer glass 1 according to the present embodiment includes a plurality of glass plates, namely glass plate 21 , glass plate 22 , and glass plate 23 , reinforcing member 3 , spacers 41 and 42 , and film 5 . In the following description, the X direction refers to the thickness direction of the double glazing 1, the Y direction refers to the width direction of the double glazing 1 orthogonal to the X direction, and the Z direction refers to the X direction and the Y direction. The height direction of the double glazing 1 orthogonal to the direction is shown.

複層ガラス１は、図１及び図２に示すように、矩形状の３枚のガラス板２１、ガラス板２２、及びガラス板２３と、上記ガラス板同士の間隙の周縁部に配置される枠状のスペーサ４１及びスペーサ４２と、を有する。ガラス板２１、ガラス板２２、及びガラス板２３は、スペーサ４１及びスペーサ４２によって隔置される。上記構成によって、中空層６が封止される。 As shown in FIGS. 1 and 2, the multi-layer glass 1 includes three rectangular glass plates 21, 22, and 23, and a frame disposed at the periphery of the gap between the glass plates. and a spacer 41 and a spacer 42 having a shape. Glass plate 21 , glass plate 22 , and glass plate 23 are separated by spacers 41 and 42 . The above configuration seals the hollow layer 6 .

ガラス板２１、ガラス板２２、及びガラス板２３は、特に限定されず、材質としてはフロート法によって製造されるフロートガラス、強化ガラス等により構成できる。また、合わせガラス、型板ガラス、網入りガラス等であってもよい。本実施形態の複層ガラス１が有するガラス板の枚数は３枚であるが、これに限定されず、２枚以上であればよい。複層ガラスの外表面に配置されるガラス板は、後述するフィルム５を挟んで形成される合わせガラスであることが好ましい。フィルム５により、スペーサや補強部材が配置される複層ガラスの周縁部を好ましく加飾できるためである。また、フィルム５に紫外線防止フィルムを用いればスペーサや補強部材の紫外線による劣化を防ぐことができる。本実施形態において、複層ガラス１の外表面に配置されるガラス板２１及びガラス板２３は合わせガラスであり、複層ガラス１の内部に配置されるガラス板２２は単板のガラス板である。ガラス板２２は、ガラス板２１及びガラス板２３よりも、Ｙ方向の長さが短く、段違いに配置される。これによって、補強部材３を配置するスペースを広く確保できる。上記に加えて、一組の補強部材３によって、３枚のガラス板を補強できる。 The glass plate 21, the glass plate 22, and the glass plate 23 are not particularly limited, and can be made of float glass manufactured by a float method, tempered glass, or the like. Laminated glass, figured glass, wired glass, or the like may also be used. Although the number of glass plates included in the multi-layer glass 1 of the present embodiment is three, the present invention is not limited to this, and the number of glass plates may be two or more. The glass plate arranged on the outer surface of the multi-layer glass is preferably laminated glass formed with a film 5 to be described later sandwiched therebetween. This is because the film 5 can preferably decorate the periphery of the double glazing on which spacers and reinforcing members are arranged. Further, if an ultraviolet protection film is used as the film 5, deterioration of spacers and reinforcing members due to ultraviolet rays can be prevented. In this embodiment, the glass plate 21 and the glass plate 23 arranged on the outer surface of the double glazing 1 are laminated glasses, and the glass plate 22 arranged inside the double glazing 1 is a single glass plate. . The glass plate 22 has a shorter length in the Y direction than the glass plates 21 and 23 and is arranged in a different level. As a result, a large space for arranging the reinforcing member 3 can be secured. In addition to the above, a set of reinforcing members 3 can reinforce three sheets of glass.

補強部材３は、複層ガラス１の撓みを抑制し、強度を確保する部材である。補強部材３は、ガラス板同士の間隙の周縁部に配置され、複数のガラス板をＸ方向に隔置する。補強部材３は、例えばガラス板同士の互いに対向する内面に当接して配置される。補強部材３は、後述するスペーサ４１及びスペーサ４２よりも、ガラス板の端縁側に配置される。補強部材３は、スペーサ４１及びスペーサ４２との間に間隔を有して配置されていてもよい。 The reinforcing member 3 is a member that suppresses bending of the double glazing 1 and ensures strength. The reinforcing member 3 is arranged at the periphery of the gap between the glass plates, and separates the plurality of glass plates in the X direction. The reinforcing member 3 is arranged, for example, in contact with the inner surfaces of the glass plates facing each other. The reinforcing member 3 is arranged closer to the edge side of the glass plate than spacers 41 and 42 which will be described later. The reinforcing member 3 may be arranged with a gap between the spacer 41 and the spacer 42 .

補強部材３は、ガラス板が３枚以上である場合、複数形成されるガラス板同士の間隙の全てに配置されることが好ましい。補強部材３は、少なくとも複層ガラス１のＹ方向及びＺ方向のうち、少なくともいずれかの方向の両端部に配置されることが好ましく、Ｙ方向及びＺ方向の両方向の両端部に配置されることがより好ましい。補強部材３は、スペーサ及び中空層６を囲うように枠状に配置されることが更に好ましい。これによって、複層ガラス１の構造が、複数のガラス板と補強部材３とが一体化したモノコック構造を有するため、各部材の強度を単に足し合わせた強度よりも高い強度を得ることができる。つまり、通常はガラス端部に用いる框体（図示しない）でガラス強度を保っていたところ、この框体のガラス１の室内外のＸ－Ｙ面に露出する幅を小さくすることができる。もしくは框体を用いずにガラス１のみとすることができる。このため、框体を枠内に収めることができ室内外から框体が見えないあるいは框体が無い仕様の建具を提供可能となる。 When the number of glass plates is three or more, the reinforcing member 3 is preferably arranged in all of the gaps between the plurality of glass plates. The reinforcing members 3 are preferably arranged at both ends of at least one of the Y direction and the Z direction of the double glazing 1, and are arranged at both ends of the Y direction and the Z direction. is more preferred. More preferably, the reinforcing member 3 is arranged in a frame shape so as to surround the spacer and the hollow layer 6 . As a result, since the structure of the multi-layer glass 1 has a monocoque structure in which a plurality of glass plates and the reinforcing member 3 are integrated, strength higher than the strength obtained by simply adding the strength of each member can be obtained. In other words, while the strength of the glass is normally maintained by a frame (not shown) used at the end of the glass, the width of the frame exposed to the XY plane inside and outside the room of the frame can be reduced. Alternatively, only the glass 1 can be used without using the frame. For this reason, the frame can be accommodated within the frame, and it is possible to provide fittings with specifications such that the frame cannot be seen from the inside and outside of the room or there is no frame.

補強部材３は、繊維強化プラスチックにより構成される。これによって、複層ガラス１に框体を有さずに建具を構成できる強度を持たせることができ、かつ断熱性を確保できる。繊維強化プラスチックの例としては、例えば、炭素繊維を補強繊維とし、熱硬化性樹脂や熱可塑性樹脂等の樹脂を含侵させて硬化させた炭素繊維強化プラスチック（ＣＦＲＰ：Ｃａｒｂｏｎ Ｆｉｂｅｒ－Ｒｅｉｎｆｏｒｃｅｄ Ｐｌａｓｔｉｃｓ）や、ガラス繊維を補強繊維として有するガラス繊維強化プラスチック（ＧＦＲＰ：Ｇｌａｓｓ Ｆｉｂｅｒ－Ｒｅｉｎｆｏｒｃｅｄ Ｐｌａｓｔｉｃｓ）等が挙げられる。繊維強化プラスチックを構成する補強繊維としては、上記以外に、アラミド繊維、ボロン繊維等であってもよい。繊維強化プラスチックは、等方性及び直交異方性繊維強化プラスチック、並びに一方向繊維強化プラスチック複合材料のうちいずれであってもよい。補強部材３は、例えばシート状の繊維強化プラスチックを貼り合わせ、オートクレーブ等で加熱することで製造できる。 The reinforcing member 3 is made of fiber-reinforced plastic. As a result, the double glazing 1 can be made strong enough to constitute fittings without a frame, and heat insulating properties can be ensured. Examples of fiber-reinforced plastics include, for example, carbon fiber-reinforced plastics (CFRP: Carbon Fiber-Reinforced Plastics) in which carbon fibers are used as reinforcing fibers, and resins such as thermosetting resins and thermoplastic resins are impregnated and cured. , glass fiber-reinforced plastics (GFRP: Glass Fiber-Reinforced Plastics) having glass fibers as reinforcing fibers, and the like. Aramid fibers, boron fibers, and the like may be used as the reinforcing fibers constituting the fiber-reinforced plastic, in addition to the above. Fiber reinforced plastics can be isotropic and orthotropic fiber reinforced plastics, and unidirectional fiber reinforced plastic composites. The reinforcing member 3 can be manufactured, for example, by bonding sheet-like fiber-reinforced plastics together and heating them in an autoclave or the like.

補強部材３は、ガラス板以上の弾性強度を有する。本明細書において、弾性強度とは、ヤング率を指し、ガラス板のヤング率はおおよそ７１６００ＭＰａである。ヤング率の測定は、ＪＩＳ Ｋ ７１６１に規定する通則に基づき、繊維強化プラスチックの種類に応じて、ＪＩＳ Ｋ ７１６４（等方性及び直交異方性繊維強化プラスチック）、及びＪＩＳ Ｋ ７１６５（一方向繊維強化プラスチック複合材料）のうちいずれかの規定に準拠して行うことができる。 The reinforcing member 3 has an elastic strength equal to or greater than that of the glass plate. As used herein, elastic strength refers to Young's modulus, and the Young's modulus of a glass plate is approximately 71600 MPa. Measurement of Young's modulus is based on the general rules specified in JIS K 7161, and according to the type of fiber reinforced plastic, JIS K 7164 (isotropic and orthotropic fiber reinforced plastic) and JIS K 7165 (unidirectional fiber reinforced plastic composite).

補強部材３は、図３に示すように、第１補強部材３１ａと、第２補強部材３２と、を有する。図３は、図１のＡ－Ａ線断面図の一部を拡大した断面図である。第１補強部材は、ガラス板の互いに対向する内面に接着されて固定される。第１補強部材は、ガラス板が３枚以上である場合、少なくとも外表面に配置される２枚のガラス板に固定されるものであればよい。本実施形態では、第１補強部材３１ａは、ガラス板２１及びガラス板２３の互いに対向する内面に対して、それぞれ接着剤Ａにより固定される２つの部材である。第１補強部材は、一部材で構成されていてもよい。第１補強部材３１ａは、ガラス面の面方向に沿って配置される面と、ガラス板の厚み方向に沿って配置される面からなる板状部材であり、図３に示すように、断面がＬ字形状を有する。 The reinforcement member 3 has the 1st reinforcement member 31a and the 2nd reinforcement member 32, as shown in FIG. FIG. 3 is a partially enlarged cross-sectional view taken along line AA of FIG. The first reinforcing member is adhered and fixed to the mutually facing inner surfaces of the glass plate. When the number of glass plates is three or more, the first reinforcing member may be fixed to at least two glass plates arranged on the outer surface. In the present embodiment, the first reinforcing members 31a are two members that are fixed with an adhesive A to the inner surfaces of the glass plate 21 and the glass plate 23 facing each other. The first reinforcing member may be composed of one member. The first reinforcing member 31a is a plate-like member having a surface arranged along the surface direction of the glass surface and a surface arranged along the thickness direction of the glass plate, and as shown in FIG. It has an L shape.

第２補強部材３２は、第１補強部材３１ａに接着されて固定される。第２補強部材３２の形状は、特に限定されないが、例えば略直方体形状を有する。第２補強部材３２のいずれかの一面が、第１補強部材３１ａのガラス板の厚み方向に沿って配置される面に対して、接着剤Ａにより固定される。第２補強部材３２は、２つの第１補強部材３１ａに対してそれぞれ接着されて固定される。これによって、ガラス板２１及びガラス板２３にそれぞれ固定された２つの第１補強部材３１ａに対して、第２補強部材３２が固定され、ガラス板と補強部材とが一体化される。 The second reinforcing member 32 is adhered and fixed to the first reinforcing member 31a. Although the shape of the second reinforcing member 32 is not particularly limited, it has, for example, a substantially rectangular parallelepiped shape. Any one surface of the second reinforcing member 32 is fixed by an adhesive A to the surface of the first reinforcing member 31a arranged along the thickness direction of the glass plate. The second reinforcing member 32 is adhered and fixed to each of the two first reinforcing members 31a. Thereby, the second reinforcing member 32 is fixed to the two first reinforcing members 31a fixed to the glass plate 21 and the glass plate 23, respectively, and the glass plate and the reinforcing member are integrated.

第１補強部材３１ａと第２補強部材３２とを有する補強部材３の上記構成により、複層ガラス１の製造工程を簡略化できる。例えば、補強部材３を一部材で構成した場合には、補強部材３をガラス板の間に挿入し、接着剤で固定することは、補強部材３を挿入する際に接着剤を削ぎ取るように移動させる事態が生じるため困難である。補強部材３の上記構成により、従来手法によりガラス板２１、ガラス板２２、及びガラス板２３の間にスペーサ４１及びスペーサ４２を配置した後に、第１補強部材３１ａをガラス板に固定し、第２補強部材３２を第１補強部材３１ａに固定できるため、容易に補強部材３をガラス板の間に接着して固定できる。 Due to the above configuration of the reinforcing member 3 having the first reinforcing member 31a and the second reinforcing member 32, the manufacturing process of the double glazing 1 can be simplified. For example, when the reinforcing member 3 is composed of a single member, inserting the reinforcing member 3 between glass plates and fixing with an adhesive causes the adhesive to be scraped off when the reinforcing member 3 is inserted. It is difficult because situations arise. With the above structure of the reinforcing member 3, after the spacers 41 and 42 are arranged between the glass plates 21, 22, and 23 by a conventional method, the first reinforcing member 31a is fixed to the glass plates, and the second reinforcing member 31a is fixed to the glass plate. Since the reinforcing member 32 can be fixed to the first reinforcing member 31a, the reinforcing member 3 can be easily adhered and fixed between the glass plates.

スペーサ４１及びスペーサ４２は、ガラス板同士の間隙に中空層６を形成する。スペーサ４１及びスペーサ４２は、補強部材３と同様に、ガラス板同士の間隙の周縁部に、ガラス板同士の互いに対向する内面に当接して配置される。スペーサ４１は、ガラス板２１及びガラス板２２を、スペーサ４２は、ガラス板２２及びガラス板２３をＸ方向に隔置する。ガラス板２１とガラス板２２との間隙、及びガラス板２２とガラス板２３との間隙にそれぞれ中空層６が形成される。スペーサ４１及びスペーサ４２は、図２及び図３に示すように、補強部材３よりもガラス板の内周側に配置される。これによって、ガラス板同士の間隙のスペーサよりも外周側に、補強部材３を配置するスペースを確保できる。上記に加えて、従来手法により複層ガラス１同士の間にスペーサ４１及びスペーサ４２を配置した後に、補強部材３を配置することができる。 Spacers 41 and spacers 42 form hollow layers 6 in the gaps between the glass plates. Similar to the reinforcing member 3, the spacers 41 and the spacers 42 are arranged at the periphery of the gap between the glass plates so as to abut against the inner surfaces of the glass plates facing each other. The spacer 41 separates the glass plates 21 and 22, and the spacer 42 separates the glass plates 22 and 23 in the X direction. A hollow layer 6 is formed in each of the gap between the glass plates 21 and 22 and the gap between the glass plates 22 and 23 . As shown in FIGS. 2 and 3, the spacers 41 and 42 are arranged closer to the inner peripheral side of the glass plate than the reinforcing member 3. As shown in FIG. Thereby, a space for arranging the reinforcing member 3 can be secured on the outer peripheral side of the spacer in the gap between the glass plates. In addition to the above, the reinforcing member 3 can be arranged after the spacers 41 and 42 are arranged between the double glazings 1 by the conventional method.

スペーサ４１及びスペーサ４２は、従来公知のものを使用できる。スペーサ４１及びスペーサ４２は、例えば、内部にゼオライト等の乾燥材が充填された中空のパイプ材と、ガラス板に対向する両側面に配置される第一シール材と、ガラス板の端縁側に配置される第二シール材により構成されるものであってもよい。上記以外に、スペーサ４１及びスペーサ４２は、樹脂系材料により一体に形成されるものであってもよい。 The spacer 41 and the spacer 42 can use a conventionally well-known thing. The spacers 41 and 42 are composed of, for example, a hollow pipe material filled with a desiccant such as zeolite, a first sealing material arranged on both sides facing the glass plate, and an edge side of the glass plate. It may be configured by a second sealing material that is In addition to the above, the spacers 41 and 42 may be integrally formed of a resin-based material.

フィルム５は、合わせガラスを構成する、２枚のガラス板の間に挟持されて配置される。本実施形態において、複層ガラス１の外表面に配置される、ガラス板２１及びガラス板２３が合わせガラスである。フィルム５は、着色されたフィルムであり、ガラス板２１及びガラス板２３の周縁部に配置される。フィルム５が配置されることで、スペーサ４１、スペーサ４２及び補強部材３がＸ方向から視認しづらいように隠蔽することができる。これによって、複層ガラス１の意匠性を向上できる。また、フィルム５に紫外線防止フィルムを用いればスペーサや補強部材の紫外線による劣化を防ぐことができる。フィルム５を合わせガラスの間に配置することで、フィルム５の剥がれや劣化を抑制できるため好ましい。フィルム５は、合わせガラスの間ではなく、例えばガラス板の外側に配置されていてもよい。 The film 5 is sandwiched between two glass plates that constitute laminated glass. In this embodiment, the glass plate 21 and the glass plate 23 arranged on the outer surface of the multi-layer glass 1 are laminated glass. The film 5 is a colored film and is arranged on the peripheral edges of the glass plate 21 and the glass plate 23 . By arranging the film 5, the spacer 41, the spacer 42, and the reinforcing member 3 can be concealed so as to be difficult to see from the X direction. Thereby, the design of the double glazing 1 can be improved. Further, if an ultraviolet protection film is used as the film 5, deterioration of spacers and reinforcing members due to ultraviolet rays can be prevented. By arranging the film 5 between the laminated glasses, peeling and deterioration of the film 5 can be suppressed, which is preferable. The film 5 may for example be arranged on the outside of the glass panes instead of between the laminated glass.

中空層６は、ガラス板２１及びガラス板２２の間隙、並びにガラス板２２及びガラス板２３の間隙に形成される。中空層６は、スペーサ４１及びスペーサ４２によって封止される。中空層６に封入されるガスは、例えば、空気、又はアルゴンガス、クリプトンガス等の不活性ガスである。 The hollow layer 6 is formed in the gap between the glass plates 21 and 22 and the gap between the glass plates 22 and 23 . The hollow layer 6 is sealed with spacers 41 and 42 . The gas enclosed in the hollow layer 6 is, for example, air or an inert gas such as argon gas or krypton gas.

次に、本発明の他の実施形態について説明する。第１実施形態と同様の構成については、説明を省略する場合がある。 Next, another embodiment of the present invention will be described. A description of the same configuration as in the first embodiment may be omitted.
