【従来の技術】ガラス板の表面にスプレー法やスパッタリング法によって金属等の酸化物薄膜を形成した熱線反射ガラスや、ガラス板面に熱線反射フイルムを貼着したガラス板は、可視光や日射光に対して優れた反射、吸収特性があり、従来より建築用や車両用の窓ガラスとして、太陽の直射光の軽減やプライバシー性の保護を目的として広く使われている。 BACKGROUND ART or heat-reflecting glass forming the oxide thin film of metal or the like on the surface of the glass plate by a spray method or a sputtering method, a glass plate was stuck the heat-reflecting film on the glass plate surface, visible light or sunlight excellent reflection against, has absorption properties, as a window glass for conventionally and architectural vehicles are widely used for protection of the direct light reduction and privacy of the sun.

【0003】一方、近年、省エネルギーの観点から建家の冷暖房負荷を軽減させるために複層ガラスが、広く普及するようになってきているが、これらの省エネ効果をより高めるために前記金属等の酸化物薄膜を形成したり、熱線反射フイルムを貼着した熱線反射ガラスを複層ガラスを構成するガラス板として用いることも良く行われている。 [0003] In recent years, multilayer glass in order to reduce the heating and cooling loads of building block from the viewpoint of energy saving, but have come to spread widely, the metal or the like in order to enhance these energy savings or forming an oxide thin film, and a heat-reflecting glass was stuck to a heat ray reflection film is made it can be used as a glass plate constituting the double glazing.

【0004】これらの複層ガラスを構成するガラス板としては、室内側、室外側ガラス共に倍強度のガラス板を用いたり、未強化ガラス(生板とも呼ばれることがある)を用いることが多く、熱線反射膜は、複層ガラスの空気層に面した側のガラス板のいずれかの面に設けられる。 [0004] As the glass plate constituting these double glazing, interior side, or a glass plate double strength to the outdoor side glass both, it is often used untempered glass (sometimes referred to as raw plate) heat ray reflective film is provided on either side of the glass plate on the side facing the air layer of the double-glazing.

【0005】例えば実開昭56−70079号公報には、熱線反射フイルム体を貼着したガラス板と他のガラス板とを、前記フイルム面を内側にして間隔をおき対立させ、その周辺部を気密に接合し一体化して成る複層ガラスが開示されている。 [0005] JP-Utility Model 56-70079, a glass plate and another glass plate bonded to the heat ray reflective film body, to conflict every apart by the film surface inwardly, the peripheral portion double glazing bonded formed by integrally discloses airtight.

【0006】あるいは、特開平1−105895号公報には、本体着色熱吸収性ガラスからなる外側ガラス板と、アニールしたガラスから成り外側ガラス板の方に向いた面上に15nm〜40nmの範囲の厚さの銀層を含む被膜を有する内側ガラス板を備えた二重ガラスユニットが開示されており、さらに、外側ガラス板を全体的にまたは部分的に強化されたガラスからなる二重ガラスユニットとしたものが開示されている。 [0006] Alternatively, JP-A-1-105895, an outer glass plate made of body colored heat absorbing glass, the range of 15nm~40nm on the surface facing towards the outer glass plate consists annealed glass double glazing unit with an inner glass plate having a coating comprising a silver layer having a thickness of are disclosed, further, a double glazed unit comprising a wholly or partly reinforced glass outer glass plate It has been disclosed those.

【発明が解決しようとする課題】前記特開平1−105 The object of the invention is to be Solved by the JP-A-1-105
895号公報に示されるもので、室外側ガラス板を強化ガラス板としたものについては、室外側ガラス板が破損した時に、破損したガラス板が全体に亘って多数の小さな破砕片となって地上に落下し、建物の高さが高くなるにつれて、前記破砕片が地上に到達するときの衝撃力が大きくなるので、安全上好ましくない。 Those represented in 895 JP, for those in which the outdoor side glass plate and tempered glass plate, when the outdoor side glass plate is broken, and throughout the broken glass plate a number of small fragments ground fall, as the building height increases, because the impact force increases when the crushed pieces reaches the ground, safety is not preferable.

【0008】このような場合には、割れたときの破片の大きさが細かくなく、窓枠のシール材の接着力によって破片を接着して支持する未強化ガラスや倍強度ガラスの方が有効であり、一般的にビル等の外壁に用いられている。 [0008] In such a case, no fine the size of the debris when broken, is effective toward the untempered glass or fold strength glass and supporting adhering debris by the adhesive force of the sealing member of the window frame There are commonly used in the outer wall of a building or the like.

【0009】一般的に強化ガラスや倍強度ガラスなど熱処理をしたガラス板は、ガラス板の内部に必然的に偏光歪みを有し、可視光透過性の高い透視性のある熱線反射ガラスを膜付けした倍強度ガラスの場合、この偏光歪みによって歪み縞模様が発生することが一般的に良く知られていたが、特に倍強度ガラスは強化ガラスとした時よりもこの縞模様の発生が顕著であった。 [0009] Generally the glass plate was heat treated like tempered glass or multiples strength glass has inevitably polarization distortion in the glass plate, film with a heat-reflecting glass with a high see-through visible light transmission for the fold strength glass, but the distortion stripe pattern generated by the polarization distortion has been generally well known, a particular fold strength glass is remarkable occurrence of stripes than when the reinforcing glass It was.

【0010】特に透明な倍強度ガラスをもう1枚組み合わせた複層ガラスとすると、つまり前記複層ガラスを構成する2枚のガラス板を倍強度ガラスとし、外側の倍強度ガラスの室内側面、つまり複層ガラスの空気層側の面に熱線反射膜を設けた場合には、倍強度ガラスのもつ内部歪みによって熱線反射膜面上にスジ状やまだら状の縞模様が単板の時に比べて一層顕著となり、室内側方向から室外をみる場合のみならず、室外側方向から室内をみる場合においても、前記縞模様によって外観上の見栄えが悪いという問題点があった。 [0010] Especially when the double glazing in combination another sheet of transparent fold strength glass, that is, the two glass plates constituting the double glazing was doubled strength glass, indoor side of the outer fold strength glass, that is in case of providing the heat-reflecting film on the surface of the air layer side of the insulating glass, streaks or mottled striped heat ray reflective film plane by internal strain with the fold strength glass even more than that when a single plate becomes significant, not only from the indoor side direction See outdoor, when viewing the interior from the outdoor side direction, the external appearance of the motorcycle is disadvantageously poor by the striped pattern.

【0011】この縞模様は、前記倍強度ガラスに透視性のある熱線反射膜等を膜付けした仕様の特有の現象であり、倍強度ガラスの製造方法によってその模様の形状に多少の違いはある。 [0011] The stripes are specific phenomena specifications put film heat-reflecting film such as a see-through to the multiplying strength glass, there are some differences in shape of the pattern by the manufacturing method of multiple strength glass .

【0012】また、前記複層ガラスを構成する2枚のガラス板を未強化ガラス(生板ガラス)とし、外側の未強化ガラスの室内側面、つまり複層ガラスの空気層側の面に熱線反射膜を設けた場合には、熱線反射膜面上にスジ状やまだら状等の縞模様の発生することはなく、室内外の両方向からみても外観上の見栄えが悪くなるということはないが、熱割れ等が発生し易くなり、強度上劣るという問題点があり、板厚構成を厚くせざるを得なかった。 Further, the the two glass plates the unreinforced glass constituting the double glazing (Namaita glass), the indoor side of the outer unreinforced glass, i.e. heat-reflecting film on the surface of the air layer side of the insulating glass the when provided not occur streaky stripes or mottled such as heat ray reflective film plane, is not that appearance on interior and exterior directions viewed even appearance is poor, heat liable cracking or the like occurs, there is a problem that it is inferior on the strength, was forced to increase the thickness configuration.

【0013】さらに、前記実開昭56−70079号公報に記載した熱線反射フイルムを貼着した複層ガラスは、ガラス板へのフイルムの均一な貼着作業に時間と手間が掛かるだけでなく、ガラス板に貼着させたフイルムの接着部分が、経年使用によって太陽光による劣化や変色の恐れがあり、見栄えが悪くなるのは避けられなかった。 Furthermore, multi-layered glass was stuck to a heat ray reflective film as described in JP-A Sho 56-70079, not only it takes time and labor to uniform sticking work of the film to the glass plate, the bonded portion of the film that was bonded to a glass plate, there is a risk of deterioration and discoloration due to sunlight by long-term use, appearance from becoming poor was inevitable.

【0018】 [0018]

【発明の実施の形態】本発明の複層ガラスGの実施例を図1に示す。 Examples of insulating glass G of the embodiment of the present invention is shown in FIG.

【0019】本発明は、対向する2枚のガラス板1、2 The present invention, glass plates 1 and 2 of the two opposing
の外周部を乾燥剤入りのスペーサー材5を介して接着後、スペーサー材5とガラス板1、2間の凹部にシーリング材6を充填密封した複層ガラスGにおいて、外側ガラス板1をその空気層4に面する側に熱遮蔽膜3を形成した未強化フロートガラス(通常、生板と称する)とし、一方、室内側ガラス板2を強化ガラスとしたものである。 After bonding the outer peripheral portion of through a spacer material 5 with a desiccant, in the double glass G filled sealed sealing material 6 into the recess between the spacer material 5 and the glass plates 1 and 2, the air outside the glass plate 1 unreinforced float glass to form a heat shielding film 3 on the side facing the layer 4 (usually referred to as raw plate), and on the other hand, is obtained by a tempered glass indoor side glass plate 2.

【0020】あるいは、前記外側ガラス1として、複数枚のガラス板をPVB(ポリビニルブチラール)等の中間膜で接着した合わせガラスとし、合わせガラスを構成するガラス板として、未強化ガラス、倍強度ガラス、強化ガラスのいずれか1つのガラス板1aと、熱遮蔽膜3 [0020] Alternatively, as the outer glass 1, a plurality of glass plates as PVB (polyvinyl butyral) laminated glass were bonded with the intermediate film such as a glass plate constituting the laminated glass, non-tempered glass, fold strength glass, and one of the glass plates 1a of tempered glass, heat-shielding layer 3
を成膜した未強化ガラス1bとからなる合わせガラス1 Laminated glass 1 consisting of a non-tempered glass 1b which was formed
とし、前記熱遮蔽膜3を空気層4に面する側に構成したものであっても良いが、この場合、未強化ガラス板と未強化ガラス板とからなる合わせガラスとするのが縞模様の発生を防止する上で好ましい。 And then, the heat shield layer 3 may be one configured on the side facing the air layer 4, but in this case, the stripes to a laminated glass consisting of untempered glass sheet and untempered glass sheet preferable for preventing the occurrence.

【0021】さらに、前記内側ガラス2についても同様に、複数枚のガラス板をPVB等の中間膜で接着した合わせガラスとし、合わせガラスを構成するガラス板として、未強化ガラス、倍強度ガラス、強化ガラスより同種又は異種のガラス板を組み合わせて接着した合わせガラスとしても良い。 Furthermore, the similarly for the inner glass 2, a plurality of glass plates and laminated glass were bonded with the intermediate film of PVB such as a glass plate constituting the laminated glass, non-tempered glass, fold strength glass, reinforced a combination of same or different glass plate from the glass may be laminated glass was bonded.

【0022】前記熱遮蔽膜3の可視光透過率は通常小さくなるに従って、内部歪みを有する強化ガラスや倍強度ガラスの板面に成膜しても内部歪みによる縞模様等は目立たないが、可視光透過率が大きくなるに従って縞模様が目立つようになる。 [0022] In accordance with the visible light transmittance of the heat shielding layer 3 is usually small, but noticeable streaks or the like due to internal strain be formed on the plate surface of the tempered glass and fold strength glass having an internal strain, visible stripes become conspicuous in accordance with the light transmittance increases. 特に、倍強度ガラスの場合は強化ガラスに比べて縞模様が強く顕れる。 In particular, in the case of double-strength glass manifested strong stripes compared to tempered glass.

【0023】しかしながら、内部歪みが倍強度ガラスに比べて非常に少ない未強化ガラスに成膜した場合には可視光透過率がある程度大きくなっても目立つことはない。 [0023] However, the visible light transmittance does not stand out even if somewhat large when the internal strain has been deposited in very small untempered glass than doubled strength glass.

室内外の両方向からみても外観上の見栄えが劣ることがない。 It never looks good on the inside and outside of both directions as viewed from even the appearance is poor.

【0044】また、複層ガラスの総厚みを倍強度ガラスと倍強度ガラスからなる複層仕様に対しても、同厚または薄く抑えたままで熱割れの発生もなく、風圧強度を維持できる。 [0044] Further, with respect to multilayer design comprising a total thickness of the double-glazing doubler strength glass and fold strength glass, without the occurrence of heat cracks while suppressing the thickness or thinner, can be maintained wind pressure strength.

【0045】さらに、万一ガラスが割れても室外側への落下の危険性が少なく、建家の冷暖房負荷も軽減でき、 [0045] In addition, even if the unlikely event cracked glass less danger of falling to the outdoor side, can also reduce heating and cooling load of the building block,
かつ、太陽の直射光の軽減やプライバシー性の保護も兼ね備え、騒音も遮断することができる。 And also it has a protective relief and privacy of sun direct light, can also block the noise.

【0046】また、前記したように、前記複層ガラスを構成する外側ガラス板、または内側ガラス板の少なくとも一方を合わせガラスとした場合においては、PVB等の樹脂フイルムにより、破損したガラスを飛散させないばかりでなく、室内に入射する紫外線をも制限しカットすることができ、これにより人体に有害な紫外線の入射を制限でき、また室内の装飾品等の退色等も防止できる。 [0046] Further, as described above, in a case where at least one of the laminated glass of the outer glass sheet or the inner glass plate constituting the multilayer glass, a resin film of the PVB or the like, does not scatter the broken glass well, limit the ultraviolet radiation incident on the chamber and can be cut, thereby to limit the incidence of harmful ultraviolet radiation to the human body, and can also prevent discoloration, etc. of indoor ornaments.

【0047】さらにまた、合わせガラスが異厚構成となることで防音効果が期待でき、乗り物等の室外からの騒音や、室外への騒音を低減を図ることができ、複層ガラスの持つ断熱性に加えて遮音、防音に対して効果がある。 [0047] Furthermore, the laminated glass can be expected soundproof effect by the different thickness configurations, and noise from the outdoor vehicles and the like, it is possible to reduce the noise of the outdoor heat insulation with the double-glazing in addition sound insulation in, it is effective against soundproofing.
