Description

【０００１】
【発明の属する技術分野】
本発明は、主に建築用に使用される合わせガラスに関する。
【０００２】
【従来の技術】
近年、建築物にはカーテンウォール工法等の外壁工法を用いて板ガラスを躯体に支持させ、これにより外壁を構築している例が増えている。板ガラスを、その周縁に取付ける部材を介して躯体に取付ける代表的な方法はサッシ構法である。すなわち、アルミニウム合金の押し出し材等の部材でフレームを形成し、該フレーム内にシーリング材を介して板ガラスを施工する方法であり、一般的な施工方法である。
【０００３】
一方、板ガラス周辺の意匠性を向上させるため、高強度のシリコーンシーリング材を用いて板ガラスの室内側にアルミニウム部材等を接着した構造シリコーン構法（以下、「ＳＳＧ構法」という）がある。また、ガラスの透視面積を極限まで追求したものに、点支持で板ガラスを支持する孔あき強化ガラス構法（以下、「ＤＰＧ構法」という）がある。ＤＰＧ構法では、強化または倍強度ガラスに孔（皿孔状の孔を含む）を加工し、特殊なボルト部材を介して板ガラスを躯体に固定する。
【０００４】
サッシ材を用いた構法は周辺の枠が不可欠であるため、透視性が低い欠点がある。ＳＳＧ構法では主に、熱線反射ガラスを用いるため、室外からの外観ではサッシ材のない優れた意匠性が得られるが、室内から見るとアルミニウム部材等が目立ち、サッシ構法と同様に意匠性が劣る。さらに、ＳＳＧ構法ではシーリング材とアルミニウム部材との接着性を充分に管理しなければならない難点がある。
【０００５】
ＤＰＧ構法は、板ガラスの室外側は極めて平滑な平面が得られるが、室内側では、支持ボルト部材と支持部材とが突き出しており、室内側に関してはフラットな表面という印象は乏しい。また、孔部の強度を一定以上にするための制限から、ボルト部材等の大きさを小さくするには限界があった。
【０００６】
建築物の外壁工法で、強化ガラスの用途として、強化ガラスを用いたドアも知られている。強化ガラスドアでは、板ガラスの４隅に複雑な加工を施し板ガラスを両側から金属プレートで挟み込む施工方式が採用されている。この方式では、表面側に金属プレートが出てきてしまうので、意匠性に劣る。
【０００７】
また、強化ガラスを使用した場合、万一の板ガラス破損の際には、破片がバラバラと飛散脱落する問題点があり、これを回避するための飛散防止フィルムを貼る等の対策が不可欠である。ただし、フィルムの耐久性には寿命があり、これをクリアするため、合わせガラスを採用することも多い。合わせガラスとは、透明で接着力の強い樹脂の中間膜を２枚以上の板ガラスで挟み込み、オートクレーブに入れ、約１３０℃の温度、約１５０ＭＰａの圧力の条件下で圧着したものである。強化合わせガラスは、飛散防止性能、耐久性能で、ともに飛散防止フィルムを貼った強化ガラスを大幅に上回る。
【０００８】
上記中間膜としては、従来よりポリビニルブチラール製のものが使用されてきたが、最近は耐水性、耐貫通性等の性能の要求から、エチレン・ビニルアセテート共重合体製のものが多用されるようになってきた。
オートクレーブ処理の際には、合わせガラスをガラス全体を包み込むようなゴム製の袋に入れて加熱加圧するが、その際、合わせガラスに部材が取付けられる場合、該部材がガラス面から飛び出していると、該部材の部分がゴム袋を引き裂くこともあり、部材取付けの障害となっていた。
【０００９】
【発明が解決しようとする課題】
本発明は、前述の課題を解決すべくなされたものであり、室内側にも室外側にも平滑な面を提供し、フレーム等の構造物がなく、透明性を追求した構法が可能であり、かつ、工場製品の出荷段階で取付部材を一体化することで、品質安定性、現場施工性を高めることができる合わせガラスを提供することを目的とする。
【００１０】
【課題を解決するための手段】
本発明は、複数枚の板ガラスが中間膜を介して接着されてなる合わせガラスにおいて、前記合わせガラスの端縁の一部では、少なくとも一枚の板ガラスは他の板ガラスより平面サイズが小さく、合わせガラスの該部位に段差部を形成しており、躯体と係合する取付部材が、前記段差部に中間膜を介して接着されおり、該平面サイズが小さな板ガラスの前記段差部の近傍にはナット部材である他のネジ状部材が埋設されており、前記取付部材の一部と前記ネジ状部材とがボルト部材であるネジ状部材を介して結合されている合わせガラスを提供する。
このような段差部に中間膜を介して取付部材が接着されていれば、オートクレーブ処理の際に取付部材がゴム袋を引き裂く不具合も解消でき、また、工場製品の出荷段階で取付部材が一体化でき、品質安定性、現場施工性が高められる。
【００１１】
本発明において、前記段差部の近傍にはネジ状部材が埋設されており、前記取付部材の一部と前記ネジ状部材とが他のネジ状部材を介して結合されることが必須である。
このように板ガラスと取付部材との固定が中間膜を介するのみならず、ネジ状部材の組合せと併用されれば、より確実な固定となる。
【００１２】
また、本発明において、前記取付部材は躯体の一部と係合され、板ガラスと躯体との間で回動機構が構成されることが好ましい。
このように、板ガラスと躯体との間で回動機構が構成されていれば、板ガラスが風圧を受けた等のときに、板ガラスに発生する応力の緩和が図れる。
【００１３】
本発明の合わせガラスの構成は、積層される板状部材の全てが無機質の板ガラスである必要はなく、無機質の板ガラスと有機質の板ガラスと通称されるもの、たとえばポリカーボネート樹脂板、アクリル樹脂板等の樹脂板とを積層した構成も、さらには、全てが有機質の板ガラスである構成をも含む。
【００１４】
なお、本発明において、合わせガラスは建築物に使用されるのが主なことより、該合わせガラスの両表面に位置する板ガラスを、便宜的に「室内側ガラス」および「室外側ガラス」という。
【００１５】
【発明の実施の形態】
本発明の合わせガラスにおいて、複数枚の板ガラスのうち、施工されたとき室内側に面して配される板ガラス（室内側ガラス）は、施工されたとき室外側に面して配される板ガラス（室外側ガラス）より部分的に平面サイズが小さく加工されており、合わせガラスとして一体化された際には該部分に段差部を形成する。
【００１６】
該段差部には、取付部材が、合わせガラス製造時に取付けられる。すなわち、中間膜を２枚の板ガラスで挟み込み、オートクレーブ処理する際に、該段差部においては、室外側ガラスと取付部材との間に中間膜を配しておく。このような構成とすることで、オートクレーブ処理により室外側ガラスと取付部材との接着固定が図れる。
【００１７】
すなわち、オートクレーブ処理により合わせガラスと取付部材とを一体的に接着できるため、品質が安定し、かつ、高接着強度が得られる。また、既に部材がセットされた状態の板ガラスパネルであるため、施工時の取り扱いが容易である。また、前記段差部がなければ室内側ガラスが存在したであろう空間に取付部材が配されるので、ＤＰＧ工法のボルト部材とは異なり、取付部材が合わせガラスのガラス面から大きく飛び出すこともない。
【００１８】
取付部材は、強力な接着力を有する中間膜によりオートクレーブで接着されるので、接着部の信頼性は高いが、さらに接合を強固にするために、機械的な接合も併有させ得る。具体的には、合わせガラスの前記段差部の近傍に皿孔加工を施しておき、該皿孔にはナット部材を埋設しておき、前記取付部材の孔にボルト部材の先端を貫通させた後、ナット部材にボルト部材の先端を螺合させる。
【００１９】
本発明における段差部は、典型的には合わせガラスの角隅部に矩形状に設けるが、辺の中間部に矩形状に設けたり、角隅部に三角形状に設けることもできる。
本発明は、壁面への板ガラスの取付、表示板（看板等）、合わせガラスドア等に利用できる。ドアに利用する場合などには、ヒンジ機構が必要となる。該ヒンジ機構では、本発明における取付部材は、構造部材側からの腕材と嵌合し、回転機構を形成する必要があるが、このような加工を取付部材に施すこともできる。
【００２０】
また、板ガラスを壁面に使用する際には、板ガラスの支持部材が回転ヒンジ機構を有していれば、風圧を受けた等のときに板ガラスに発生する応力の緩和に有効である。
この場合、正方形の板ガラスであれば、板ガラス角隅部において板ガラスの辺に対して約４５度方向に回転ヒンジを設けることが好ましい。横長の長方形板ガラスであれば、縦辺に回転ヒンジを設けることが好ましい。ヒンジは一方向の回転のみであるため、取付部材と嵌合する躯体側の腕材等に、さらに前記ヒンジ軸と直交する方向の回転機構を設ければ、応力緩和性能はさら向上する。
【００２１】
【実施例】
図１は、本発明の合わせガラスの実施例の要部断面図であり、図２は、要部斜視図である。合わせガラス１は、室外側ガラス２、室内側ガラス３、中間膜５、取付部材７等より構成される。合わせガラス１は、端縁部において室外側ガラス２が室内側ガラス３より張り出して段差部４を形成している。また、合わせガラス１の端縁から所定距離の位置において、室内側ガラス３には皿孔６が加工されている。そして、皿孔６にはネジ状部材（ナット部材）９が配されている。
【００２２】
合わせガラス１には、強化または倍強度ガラスを用いるのが好ましい。皿孔６は、合わせガラス１の２枚の板ガラス２、３を貫通するものでもよいが、室外側ガラス２の表面を平滑に保つためには、図１に示すように室内側ガラス３のみに設けるのが望ましい。皿孔６には、アルミニウム等からなる緩衝材１０を介してナット部材９が配される。ボルト部材１１の先端が、取付部材７の孔を貫通してナット部材９に緊締螺合されることで、取付部材７と合わせガラス１とが機械的に結合される。
【００２３】
なお、図１の例では、皿孔６にナット部材９を配し、ボルト部材１１を取付部材７の孔を貫通させナット部材９に緊締螺合させる構成を採ったが、該構成に限定されない。たとえば、まず、皿孔６に該皿孔６に嵌合する形状のボルト部材をボルト部材の先端が室内側ガラス３を貫通するように配し、次に、取付部材７の孔をボルト部材の先端が貫通するようにして取付部材７を配し、その後、ボルト部材、取付部材７および合わせガラス１を一体化し、最後に、ナット部材をボルト部材の先端に緊締螺合させる構成であってもよい。
【００２４】
また、皿孔６のような形状の孔とする代りに、たとえば、室内側ガラス３の孔を口径の異なる段差を設けた孔とし、ナット部材９が室内側に抜けないようにした構成であってよく、室外側ガラス２と室内側ガラス３とに口径の異なる貫通孔を形成し、室外側ガラス２と室内側ガラス３とで段差を設けた孔を構成させ、ナット部材９が室内側に抜けないようにした構成であってもよい。
【００２５】
合わせガラス１の躯体への取付けは、取付部材７の小口面に設けられた溝８に、躯体側からの支持部材１２を挿入して行われる。この場合、溝部８は、入口の溝幅よりも奥の方の溝幅が大きく形成されており、支持部材１２の先端部分は均一の厚さであるため、溝部８と支持部材１２とで一種のヒンジ機構を構成する。すなわち、取付部材７の溝８の入口と支持部材１２との接触点を中心として、合わせガラス１は若干の角度だけ回動する。これにより、風圧を受けた等のときの、板ガラスに発生する応力の緩和が図れる。
【００２６】
皿孔６に配されるナット部材９、緩衝材１０は、取付部材７と同様に、合わせガラス製造時（オートクレーブ処理の際）において、中間膜５により、合わせガラスに一体化される。図１、図２の場合は、合わせガラスの室内側の面が完全な平坦面ではなくなるが、従来のＤＰＧ構法と比較すると、取付部材の出っ張りの程度は小さくなり、かなり改善されている。
【００２７】
図３は、本発明の合わせガラスをファサードに使用した実施例の正面図であり、取付部材７の取付位置および形状を示す。（ａ）は図１、図２に示した実施例のもので、合わせガラス１を四隅で支持したものである。（ｂ）は、合わせガラス１の室内側ガラス３の四隅を辺に対し約４５度の角度で切り落とし、取付部材７の溝８と支持部材１２とで構成されるヒンジ回転軸を、辺に対し約４５度傾けて設置した例である。合わせガラス１が正方形の場合、図３（ｂ）のようにヒンジ機構を辺に対し約４５度傾けて設置することで、風圧を受けた等のときの、板ガラスに発生する応力の緩和機能は、最も効果的となる。（ｃ）は、合わせガラス１の縦二辺の全長に取付部材７を取付けた例である。
【００２８】
図４は、参考例の要部断面図である。図４の例では、板ガラスに孔加工等することなく、合わせガラス１と取付部材７とが、ほとんど突起部分を生じさせずに一体化される。合わせガラス１は、室内側ガラス３が部分的または辺全体において室外側ガラス２より小さく、段差部４を構成しており、段差部４に取付部材７が中間膜５により接着されている。
【００２９】
取付部材７は、末端に筒状部１３を有しており、躯体または建具の支持部材の軸部（図示せず）と係合されヒンジ機構を構成する。この構成では、正風圧状態においては、耐風圧性能は取付部材の強度に依存し、負風圧状態においては、耐風圧性能は取付部材７と中間膜５との接着性能に依存していることとなる。なお、金属（取付部材７）と中間膜５との接着強度は十分であることが確認されている。
【００３０】
図５は、本発明の合わせガラスの、さらに他の実施例の要部断面図であり、図６は、要部斜視図である。いずれも、本発明をドアに使用した場合を想定している。合わせガラス１に中間膜５、ナット部材９等を使用して取付部材７が取付けられる構成は、図１、図２に示される実施例と同様である。
【００３１】
図５、図６の構成においては、図１、図２に示される実施例における溝８の代りに筒状部１３が形成されている。筒状部１３には、躯体または建具の支持部材の軸部１４が嵌合され、ヒンジ機構を構成する。合わせガラスドアの該ヒンジ機構により、合わせガラスドアは回動自在となる。
なお、同様のヒンジ機構を、建築物壁面のファサードにも応用できる。
【００３２】
上述の各実施例では、全て室外側ガラスと室内側ガラスとの２枚の板ガラスで合わせガラスを構成しているが、これに限定されず、３枚以上の板ガラスで合わせガラスを構成した場合にも本発明は適用でき、よくその機能を発揮し得る。
【００３３】
【発明の効果】
本発明により、強力な接着力の中間膜で一体に取付部材を接着した合わせガラスが得られる。また、一方の板ガラス（室内側ガラス）の平面サイズが小さく、段差部が形成されているため、合わせガラスから取付部材が大きく突出することはなく、平坦な面が形成される。
【００３４】
また、合わせガラスと取付部材とが機械的にも結合されているので、中間膜での接着に加え、より確実な固定が得られる。
さらに、取付部材は躯体の一部と係合され、板ガラスと躯体との間で回動機構が構成されるので、板ガラスが風圧を受けた等のときに、板ガラスに発生する応力の緩和が図れる。

BACKGROUND OF THE INVENTION
The present invention relates to a laminated glass mainly used for construction.
[0002]
[Prior art]
In recent years, there are an increasing number of buildings in which an outer wall is constructed by supporting a plate glass on a casing using an outer wall method such as a curtain wall method. A typical method of attaching the plate glass to the housing through a member attached to the peripheral edge is a sash construction method. In other words, this is a general construction method in which a frame is formed by a member such as an extruded material of aluminum alloy, and a plate glass is constructed in the frame via a sealing material.
[0003]
On the other hand, there is a structural silicone construction method (hereinafter referred to as “SSG construction method”) in which an aluminum member or the like is bonded to the indoor side of the plate glass using a high-strength silicone sealing material in order to improve the design properties around the plate glass. Further, there is a perforated tempered glass construction method (hereinafter referred to as “DPG construction method”) that supports a plate glass with a point support in pursuit of the transparent area of glass. In the DPG construction method, holes (including countersunk holes) are processed in tempered or double strength glass, and the plate glass is fixed to the housing via a special bolt member.
[0004]
The construction method using the sash material has a drawback that the transparency is low because the surrounding frame is indispensable. In the SSG construction method, heat ray reflective glass is mainly used, so that an excellent design without a sash material can be obtained from the outside, but when viewed from the inside, aluminum members are conspicuous and the design is inferior as in the sash construction. . Furthermore, in the SSG construction method, there is a difficulty in sufficiently managing the adhesiveness between the sealing material and the aluminum member.
[0005]
In the DPG construction method, an extremely smooth flat surface can be obtained on the outdoor side of the plate glass, but the support bolt member and the support member protrude on the indoor side, and the impression of a flat surface on the indoor side is poor. In addition, there is a limit in reducing the size of the bolt member and the like due to the restriction to make the strength of the hole part a certain level or more.
[0006]
A door using tempered glass is also known as an application of tempered glass in the outer wall construction method of buildings. The tempered glass door employs a construction method in which complicated processing is applied to the four corners of the plate glass, and the plate glass is sandwiched between the metal plates from both sides. In this method, the metal plate comes out on the surface side, so that the design is inferior.
[0007]
In addition, when tempered glass is used, there is a problem that fragments are scattered and dropped in the event of a plate glass breakage, and measures such as applying a scattering prevention film to avoid this are indispensable. However, the durability of the film has a lifetime, and in order to clear this, laminated glass is often adopted. Laminated glass is obtained by sandwiching a transparent and strong adhesive resin interlayer between two or more plate glasses, placing them in an autoclave, and press-bonding them under conditions of a temperature of about 130 ° C. and a pressure of about 150 MPa. The tempered laminated glass is much better than the tempered glass with the anti-scattering film on it.
[0008]
As the intermediate film, those made of polyvinyl butyral have been used, but recently, those made of ethylene / vinyl acetate copolymer are often used due to demands for performance such as water resistance and penetration resistance. It has become.
In autoclave treatment, the laminated glass is put in a rubber bag that wraps the whole glass and heated and pressurized. At that time, when the member is attached to the laminated glass, the member protrudes from the glass surface. The part of the member may tear the rubber bag, which is an obstacle to the attachment of the member.
[0009]
[Problems to be solved by the invention]
The present invention has been made to solve the above-mentioned problems, and provides a smooth surface both indoors and outdoors, and there is no structure such as a frame, and a construction method pursuing transparency is possible. And it aims at providing the laminated glass which can improve quality stability and on-site construction property by integrating an attachment member in the shipment stage of a factory product.
[0010]
[Means for Solving the Problems]
The present invention relates to a laminated glass in which a plurality of sheet glasses are bonded via an intermediate film, and at least a part of the sheet glass has a smaller planar size than other sheet glasses at a part of the edge of the laminated glass, and the laminated glass A step member is formed in the portion of the plate, a mounting member that engages with the housing is bonded to the step member through an intermediate film, and a nut member is provided in the vicinity of the step member of the plate glass having a small planar size. A laminated glass in which another screw-like member is embedded and a part of the mounting member and the screw-like member are coupled via a screw-like member that is a bolt member is provided.
If the mounting member is bonded to such a step through an intermediate film, the problem of the mounting member tearing the rubber bag during autoclaving can be eliminated, and the mounting member is integrated at the factory product shipping stage. It is possible to improve quality stability and on-site workability.
[0011]
In the present invention, a screw-like member is embedded in the vicinity of the stepped portion, and it is essential that a part of the mounting member and the screw-like member are coupled via another screw-like member.
In this way, not only the fixing of the plate glass and the mounting member is performed via the intermediate film, but also when the combination of the screw-shaped members is used together, the fixing is more sure.
[0012]
Moreover, in this invention, it is preferable that the said attachment member is engaged with a part of housing | casing, and a rotation mechanism is comprised between plate glass and a housing body.
Thus, if the rotation mechanism is configured between the plate glass and the housing, the stress generated in the plate glass can be reduced when the plate glass is subjected to wind pressure or the like.
[0013]
The laminated glass of the present invention does not require that all of the laminated plate-like members are inorganic plate glasses, but is commonly referred to as inorganic plate glass and organic plate glass, such as polycarbonate resin plates and acrylic resin plates. The configuration in which the resin plates are laminated also includes a configuration in which all are organic plate glasses.
[0014]
In the present invention, since laminated glass is mainly used for buildings, the plate glasses located on both surfaces of the laminated glass are referred to as “indoor glass” and “outdoor glass” for convenience.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
In the laminated glass of the present invention, among a plurality of plate glasses, a plate glass (indoor glass) arranged facing the indoor side when constructed is a plate glass arranged facing the outdoor side when constructed (inside glass). The planar size is partially processed smaller than the outdoor glass), and when the laminated glass is integrated, a step portion is formed in the portion.
[0016]
An attachment member is attached to the step portion when the laminated glass is manufactured. That is, when the intermediate film is sandwiched between two plate glasses and autoclaved, the intermediate film is disposed between the outdoor glass and the attachment member at the stepped portion. By setting it as such a structure, the adhesion fixation of outdoor side glass and an attachment member can be aimed at by an autoclave process.
[0017]
That is, since the laminated glass and the mounting member can be integrally bonded by autoclaving, the quality is stable and high adhesive strength is obtained. Moreover, since it is a sheet glass panel in which a member has already been set, handling during construction is easy. Moreover, since the mounting member is arranged in the space where the indoor side glass would exist if there is no stepped portion, the mounting member does not jump out of the glass surface of the laminated glass unlike the bolt member of the DPG method. .
[0018]
Since the attachment member is bonded by an autoclave with an intermediate film having a strong adhesive force, the reliability of the bonded portion is high, but in order to further strengthen the bonding, mechanical bonding can be combined. Specifically, a countersunk hole is formed in the vicinity of the stepped portion of the laminated glass, a nut member is embedded in the countersunk hole, and the tip of the bolt member is passed through the hole of the mounting member. The tip of the bolt member is screwed into the nut member.
[0019]
The step portion in the present invention is typically provided in a rectangular shape at the corner of the laminated glass, but may be provided in a rectangular shape in the middle of the side or in a triangular shape at the corner.
INDUSTRIAL APPLICABILITY The present invention can be used for attachment of plate glass to a wall surface, a display plate (signboard, etc.), a laminated glass door, and the like. When used for a door, a hinge mechanism is required. In the hinge mechanism, the attachment member in the present invention needs to be fitted with the arm member from the structural member side to form a rotation mechanism, but such processing can also be applied to the attachment member.
[0020]
Further, when the plate glass is used for the wall surface, if the plate glass support member has a rotating hinge mechanism, it is effective for alleviating the stress generated in the plate glass when subjected to wind pressure or the like.
In this case, if it is square plate glass, it is preferable to provide a rotation hinge in the direction of about 45 degree | times with respect to the edge | side of plate glass in a corner corner of plate glass. In the case of a horizontally long rectangular plate glass, it is preferable to provide a rotary hinge on the vertical side. Since the hinge is rotated only in one direction, the stress relaxation performance is further improved if a rotation mechanism in a direction perpendicular to the hinge axis is provided on the arm member on the housing side that fits with the mounting member.
[0021]
【Example】
FIG. 1 is a cross-sectional view of the main part of an embodiment of the laminated glass of the present invention, and FIG. 2 is a perspective view of the main part. The laminated glass 1 includes an outdoor side glass 2, an indoor side glass 3, an intermediate film 5, an attachment member 7, and the like. In the laminated glass 1, the outdoor side glass 2 projects from the indoor side glass 3 at the end edge portion to form a stepped portion 4. In addition, a countersink 6 is processed in the indoor glass 3 at a position a predetermined distance from the edge of the laminated glass 1. A screw-like member (nut member) 9 is disposed in the countersunk hole 6.
[0022]
The laminated glass 1 is preferably tempered or double strength glass. The countersink 6 may pass through the two glass plates 2 and 3 of the laminated glass 1, but in order to keep the surface of the outdoor glass 2 smooth, only the indoor glass 3 is used as shown in FIG. It is desirable to provide it. A nut member 9 is disposed in the countersink 6 via a cushioning material 10 made of aluminum or the like. The front end of the bolt member 11 passes through the hole of the attachment member 7 and is tightened and screwed to the nut member 9, whereby the attachment member 7 and the laminated glass 1 are mechanically coupled.
[0023]
In the example of FIG. 1, the nut member 9 is disposed in the countersunk hole 6 and the bolt member 11 passes through the hole of the mounting member 7 and is tightened and screwed to the nut member 9. However, the configuration is not limited thereto. . For example, first, a bolt member shaped to fit into the countersunk hole 6 is disposed in the countersunk hole 6 so that the tip of the bolt member penetrates the indoor glass 3, and then the hole of the mounting member 7 is made of the bolt member Even if the mounting member 7 is arranged so that the tip penetrates, then the bolt member, the mounting member 7 and the laminated glass 1 are integrated, and finally the nut member is tightly screwed to the tip of the bolt member. Good.
[0024]
Further, instead of the hole having the shape like the countersunk hole 6, for example, the hole in the indoor side glass 3 is provided with a step having a different diameter so that the nut member 9 does not come out indoors. A through-hole having a different diameter is formed in the outdoor side glass 2 and the indoor side glass 3, and a hole provided with a step is constituted by the outdoor side glass 2 and the indoor side glass 3, and the nut member 9 is located on the indoor side. The configuration may be such that it does not come off.
[0025]
Attachment of the laminated glass 1 to the housing is performed by inserting a support member 12 from the housing side into a groove 8 provided on the small face of the attachment member 7. In this case, the groove portion 8 is formed so that the groove width at the back is larger than the groove width of the inlet, and the tip portion of the support member 12 has a uniform thickness. Therefore, the groove portion 8 and the support member 12 are of a kind. The hinge mechanism is configured. That is, the laminated glass 1 rotates by a slight angle around the contact point between the inlet of the groove 8 of the mounting member 7 and the support member 12. As a result, it is possible to relieve the stress generated in the sheet glass when subjected to wind pressure or the like.
[0026]
The nut member 9 and the cushioning material 10 arranged in the countersunk hole 6 are integrated with the laminated glass by the intermediate film 5 when the laminated glass is manufactured (at the time of autoclaving), similarly to the mounting member 7. In the case of FIGS. 1 and 2, the surface on the indoor side of the laminated glass is not a completely flat surface, but compared with the conventional DPG construction method, the degree of the protrusion of the mounting member is reduced and considerably improved.
[0027]
FIG. 3 is a front view of an embodiment in which the laminated glass of the present invention is used for a facade, and shows the mounting position and shape of the mounting member 7. (A) is a thing of the Example shown in FIG. 1, FIG. 2, and is supporting the laminated glass 1 in the four corners. (B) cuts off the four corners of the indoor side glass 3 of the laminated glass 1 at an angle of about 45 degrees with respect to the side, and the hinge rotation axis constituted by the groove 8 of the mounting member 7 and the support member 12 is This is an example of being installed at an angle of about 45 degrees. When the laminated glass 1 is square, the function of relieving the stress generated in the plate glass when the wind pressure is received by installing the hinge mechanism tilted at about 45 degrees with respect to the side as shown in FIG. Will be the most effective. (C) is an example in which the attachment member 7 is attached to the entire length of two vertical sides of the laminated glass 1.
[0028]
FIG. 4 is a cross-sectional view of a main part of a reference example . In the example of FIG. 4, the laminated glass 1 and the mounting member 7 are integrated with each other with almost no projecting portion without drilling the plate glass. In the laminated glass 1, the indoor side glass 3 is partially or entirely smaller than the outdoor side glass 2 to form a stepped portion 4, and an attachment member 7 is bonded to the stepped portion 4 by an intermediate film 5.
[0029]
The attachment member 7 has a cylindrical portion 13 at the end, and is engaged with a shaft portion (not shown) of a support member of a frame or joinery to constitute a hinge mechanism. In this configuration, the wind resistance performance depends on the strength of the mounting member in the positive wind pressure state, and the wind resistance performance depends on the bonding performance between the mounting member 7 and the intermediate film 5 in the negative wind pressure state. Become. It has been confirmed that the adhesive strength between the metal (mounting member 7) and the intermediate film 5 is sufficient.
[0030]
FIG. 5 is a cross-sectional view of a main part of still another embodiment of the laminated glass of the present invention, and FIG. 6 is a perspective view of the main part. In any case, the case where the present invention is used for a door is assumed. The structure in which the attachment member 7 is attached to the laminated glass 1 using the intermediate film 5, the nut member 9 and the like is the same as the embodiment shown in FIGS.
[0031]
5 and 6, a cylindrical portion 13 is formed instead of the groove 8 in the embodiment shown in FIGS. 1 and 2. The cylindrical portion 13 is fitted with a shaft portion 14 of a support member for a frame or joinery to constitute a hinge mechanism. The laminated glass door is rotatable by the hinge mechanism of the laminated glass door.
A similar hinge mechanism can be applied to the facade of a building wall.
[0032]
In each of the above-described embodiments, the laminated glass is composed of two sheet glasses of the outdoor side glass and the indoor side glass, but is not limited thereto, and when the laminated glass is composed of three or more sheet glasses. However, the present invention is applicable and can perform its function well.
[0033]
【The invention's effect】
According to the present invention, a laminated glass can be obtained in which an attachment member is integrally bonded with an intermediate film having a strong adhesive force. Moreover, since the planar size of one plate glass (interior side glass) is small and the step portion is formed, the mounting member does not protrude greatly from the laminated glass, and a flat surface is formed.
[0034]
In addition, since the laminated glass and the mounting member are mechanically coupled, more reliable fixing can be obtained in addition to adhesion with the intermediate film.
Furthermore, since the mounting member is engaged with a part of the housing and a rotating mechanism is configured between the plate glass and the housing, the stress generated in the plate glass can be reduced when the plate glass is subjected to wind pressure or the like. .
