Description

本発明は、複層ガラス窓の施工用押え冶具および複層ガラス窓の施工方法に関する。   The present invention relates to a pressing jig for the construction of a multilayer glass window and a construction method of a multilayer glass window.

２枚のガラス板を、スペーサを介して隔置し、中空層が形成されてなる複層ガラスは、断熱性及び防音性に優れており、ビル用、住宅用、その他各種建造物の窓用として広く普及している。
一方、建造物に施工されている既存の単板構成のガラス窓に、新規のガラス板を並設することによって、前記ガラス窓を複層ガラス窓に改築することが、例えば特許文献１に提案されている。既存のガラス窓を複層ガラス窓の一部として利用することにより、新たに複層ガラスを嵌め込む場合に比べ、施工費を削減できるとともに、施工期間の短縮、既存のガラス窓の廃棄が不要、及びサッシの交換が不要という利点がある。 Double-layer glass with two glass plates separated by a spacer and formed with a hollow layer is excellent in heat insulation and soundproofing, and is used for windows in buildings, houses, and other various structures. As widely used.
On the other hand, for example, Patent Document 1 proposes that the glass window is remodeled into a double-glazed glass window by arranging a new glass plate in parallel with an existing single-panel glass window constructed in a building. Has been. Using existing glass windows as part of a multi-layer glass window reduces construction costs, shortens the construction period, and eliminates the need to discard existing glass windows compared to the case where a new multi-layer glass is fitted. And there is an advantage that no sash replacement is required.

複層ガラス窓化のために、新規なガラス板にスペーサを接着したものを既存のガラス窓に取り付ける施工方法は、例えば、一方の側面にブチルゴム（一次シール材）が形成されたスペーサをガラス窓の周縁部にブチルゴムを介して接着し、次いで、前記スペーサの他方の側面に新規のガラス板をブチルゴムによって接着し、次いで、既存のガラス窓と新規のガラス板との間の端縁部の隙間に形状保持のためのシール材（二次シール材）を打設する工程を経る。
しかしながら、前記した既存のガラス窓に新規のガラス板を取り付ける複層ガラス窓の組立方法では、一次シール材であるブチルゴムを、スペーサ付きガラス板と既存のガラス窓との双方に施工現場にて接着するため、施工現場での複層ガラス窓の組立作業に手間がかかるという問題点があった。 In order to make a double-glazed glass window, a method of attaching a new glass plate with spacers attached to an existing glass window is, for example, using a glass window with a spacer with butyl rubber (primary sealant) formed on one side. Is bonded to the peripheral portion of the spacer with butyl rubber, and then a new glass plate is bonded to the other side of the spacer with butyl rubber, and then the edge gap between the existing glass window and the new glass plate Then, a step of placing a sealing material (secondary sealing material) for maintaining the shape is performed.
However, in the method of assembling a multi-layer glass window in which a new glass plate is attached to the existing glass window, the primary sealing material butyl rubber is bonded to both the glass plate with the spacer and the existing glass window at the construction site. Therefore, there is a problem that it takes time to assemble the multi-layer glass window at the construction site.

かかる問題点の解決が図られた複層ガラス窓を施工現場にて容易に組み立てることができるスペーサ付きガラス板及び複層ガラス窓の組立方法が、特許文献２として提案されている。特許文献２に記載の複層ガラス窓の施工方法は、既存の矩形状のガラス窓に、複層ガラス化するためのシール材としてのブチルゴムが塗工されたスペーサを周辺部に有する矩形状のスペーサ付きガラス板を、スペーサを介して配した後、前記ブチルゴムをガラス窓に圧着させることにより、スペーサ付きガラス板を既存のガラス窓に取付けている。その圧着方法としては、スペーサ付きガラス板の表面からスペーサに沿ってローラーを押しつけて走行させることにより行うことが記載されている。一方、作業員が施工現場で、既存のガラス窓にスペーサ付きガラス板を取り付けた後、作業員が手で押すという手法も行なわれていた。   Patent Document 2 proposes a glass plate with a spacer and a method for assembling a multi-layer glass window that can easily assemble a multi-layer glass window in which such problems are solved at a construction site. The construction method of the double glazing window described in Patent Document 2 is a rectangular glass window having a spacer coated with butyl rubber as a sealing material for forming a double glazing on an existing rectangular glass window. After arranging the glass plate with a spacer through the spacer, the glass plate with the spacer is attached to the existing glass window by pressing the butyl rubber onto the glass window. As the press bonding method, it is described that the pressing is performed by pressing a roller along the spacer from the surface of the glass plate with the spacer. On the other hand, after a worker attaches a glass plate with a spacer to an existing glass window at a construction site, the worker pushes it by hand.

ブチルゴムは、ローラーの押し付け圧に対して反発する性質を有しているため、ローラーによる圧着方法では、シール材をガラス窓に確実に圧着することが難しいという問題点が見出された。そこで、特許文献３では、複層ガラス窓化した後、その空気層の空気を吸引し、空気層を減圧しながらシール材を既存のガラス窓を徐々に押圧させていくことにより、シール材を既存のガラス窓に圧着させることが提案されている。   Since butyl rubber has a property of repelling against the pressing pressure of the roller, it has been found that it is difficult to reliably press the sealing material to the glass window by the pressing method using the roller. Therefore, in Patent Document 3, after forming a multi-layer glass window, the air in the air layer is sucked and the sealing material is gradually pressed against the existing glass window while depressurizing the air layer. It has been proposed to crimp an existing glass window.

しかしながら、特許文献２および特許文献３のいずれの方法も、矩形状のスペーサ付きガラス板を、既存のガラス窓に配してシール材を介して圧着させる際、隅部においてスペーサ付きガラス板の反り返りが発生することがあり、４隅部においてシール材の圧着不良が生じる問題点や、隅部の圧着の安定性のばらつきによる耐久性不良の問題点や、寸法精度の誤差が生じる問題点があった。   However, in both methods of Patent Document 2 and Patent Document 3, when a rectangular glass plate with a spacer is arranged on an existing glass window and crimped via a sealing material, the glass plate with a spacer is warped at the corner. There is a problem that the seal material is poorly crimped at the four corners, a problem of durability failure due to variations in the crimping stability of the corners, and a problem of dimensional accuracy error. It was.

図１、２に示すように、複層ガラス窓を施工する現場にて、既存の矩形状のガラス窓１に矩形状のスペーサ付きガラス板２を取り付けることで複層ガラス窓３が組み立てられる。スペーサ付きガラス板２は、施工性および耐久性を考慮して、通常は室内側面に取付けられる。 DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of a pressing jig for construction of a multilayer glass window and a construction method of a multilayer glass window according to the present invention will be described with reference to the accompanying drawings. In this explanation, in order to facilitate understanding, first, a construction method of a multi-layer glass window will be explained.
As shown in FIGS. 1 and 2, a multi-layer glass window 3 is assembled by attaching a rectangular glass plate 2 with a spacer to an existing rectangular glass window 1 at a site where a multi-layer glass window is to be constructed. In consideration of workability and durability, the glass plate 2 with a spacer is usually attached to the side surface of the room.

建造物の開口部に嵌め込まれたガラス窓１は、図３に示されるごとく、通常、その上辺においては、上側の枠体３１に嵌め込まれ、シーラント材３２によって接着されており、また、下辺においては、ガラス窓１の小口面に対応する部分の所定箇所に配されたセッティングブロック３３を介して下側の枠体３４に嵌め込まれ、ガラス窓１の下辺においても枠体３４にシーラント材３５によって接着されている。図示していないが、ガラス窓の左右の縦辺も同様に枠体の縦部に嵌め込まれ、シーラント材によって接着されている。   As shown in FIG. 3, the glass window 1 fitted in the opening of the building is usually fitted on the upper frame 31 on the upper side and bonded by the sealant material 32, and on the lower side. Is fitted into the lower frame body 34 via a setting block 33 disposed at a predetermined position corresponding to the small edge of the glass window 1, and the sealant material 35 is also attached to the frame body 34 at the lower side of the glass window 1. It is glued. Although not shown, the left and right vertical sides of the glass window are similarly fitted into the vertical portion of the frame and are bonded by a sealant material.

スペーサ付きガラス板２は、ガラス窓１とともに複層ガラス窓を構成するガラス板であり、矩形状のガラス板２１と、シール材２２と、スペーサ２３と、シール材２４とを有している。矩形状のガラス板２１は、既存の矩形状のガラス窓１のうち枠体４に嵌め込まれた部分を除いた露出の寸法より小さいサイズのガラス板である。より具体的には、図１のように、スペーサ付きガラス板２のガラス窓１への取付けが容易となるように、矩形状のガラス板２１の４辺の端面とガラス窓１の枠体４に嵌め込まれた部分の境界線との間隔Ｐが１５ｍｍ以上確保されるような、ガラス窓１より小サイズの寸法のガラス板２１であるのが好ましい。   The glass plate 2 with a spacer is a glass plate that forms a multi-layer glass window together with the glass window 1, and includes a rectangular glass plate 21, a sealing material 22, a spacer 23, and a sealing material 24. The rectangular glass plate 21 is a glass plate having a size smaller than the exposed dimension excluding the portion of the existing rectangular glass window 1 fitted into the frame body 4. More specifically, as shown in FIG. 1, the end surfaces of the four sides of the rectangular glass plate 21 and the frame body 4 of the glass window 1 so that the glass plate 2 with spacers can be easily attached to the glass window 1. It is preferable that the glass plate 21 has a size smaller than that of the glass window 1 so that a distance P of 15 mm or more from the boundary line of the portion fitted into the glass window 1 is secured.

例えば、矩形状のスペーサ付きガラス板２のガラス板２１は、図４のように、施工された既存の矩形状のガラス窓１の内側に納まる小サイズの寸法とし、ガラス窓１の周縁部に間隔Ｌ、Ｍ、Ｎ、Ｏが形成されるように配される。通常、ガラス窓の周辺部は、建築物の窓の開口部の枠体に所定の呑込み寸法をもって納まるように施工される。従って、枠体から露出したガラス窓１の辺と、対応するガラス板２１の辺との間の間隔Ｌ、Ｍ、Ｎ、Ｏの寸法は、例えば、それぞれ１８ｍｍ程度となる様に、スペーサ付きガラス板の横寸法は、ガラス窓の横寸法より小さくし、またスペーサ付きガラス板の縦寸法は、ガラス窓の縦寸法より小さくする。なお、図４において、斜線で示したガラス窓１の周辺部分Ｂは、ガラス窓１の枠体に納まった部分を示し、線Ｃがガラス窓１の枠体に納まった部分とガラス窓１の透視部分との境界線であり、この境界線の内側が建築物の窓の開口部に施工されたガラス窓の透視有効領域となる。
また、ガラス窓およびスペーサ付きガラス板のそれぞれの板厚としては、ガラス窓１の強度を損なうことなく、複層ガラス窓の軽量化、施工しやすさの面から、スペーサ付きガラス板の板厚は、ガラス窓のガラス板厚と同等または薄い方が好ましい。例えば、スペーサ付きガラス板の板厚は、５〜１２ｍｍが実用的である。 For example, the glass plate 21 of the glass plate 2 with a rectangular spacer has a small size that fits inside the existing rectangular glass window 1 as shown in FIG. It arrange | positions so that the space | interval L, M, N, and O may be formed. Usually, the peripheral part of the glass window is constructed so as to fit in the frame of the opening part of the window of the building with a predetermined penetration size. Accordingly, the glass with spacers is set so that the distances L, M, N, and O between the side of the glass window 1 exposed from the frame and the side of the corresponding glass plate 21 are about 18 mm, for example. The horizontal dimension of the plate is smaller than the horizontal dimension of the glass window, and the vertical dimension of the glass plate with spacers is smaller than the vertical dimension of the glass window. In FIG. 4, a peripheral portion B of the glass window 1 indicated by hatching indicates a portion that is accommodated in the frame of the glass window 1, and a portion in which the line C is accommodated in the frame of the glass window 1 and the glass window 1. This is a boundary line with the see-through portion, and the inside of this boundary line becomes the see-through effective area of the glass window constructed in the opening of the window of the building.
In addition, the thickness of the glass window and the glass plate with a spacer is not limited to the thickness of the glass window 1, and the thickness of the glass plate with the spacer is reduced in terms of weight reduction and ease of construction of the multi-layer glass window. Is preferably equal to or thinner than the glass plate thickness of the glass window. For example, the thickness of the glass plate with a spacer is practically 5 to 12 mm.

スペーサ付きガラス板２としては、例えば、ガラス板２１の一方の面の周縁部よりも内側であって、枠状のスペーサ２３のガラス板２１と面する部分の両方の側面に、予めシール材を塗工して形成されたシール材２２、２４付きのスペーサ付きガラス板２が使用される。あるいは、ガラス板２１の一方の面の周縁部よりも内側であって、枠状のスペーサ２３の一方の側面が配置される部分に、または枠状のスペーサ２３のガラス板２１と面する部分の側面に、予めシール材を塗工して形成されたシール材２２付きのスペーサ付きガラス板２が使用される。   As the glass plate 2 with a spacer, for example, a sealing material is previously applied to both side surfaces of a portion facing the glass plate 21 of the frame-like spacer 23 inside the peripheral portion of one surface of the glass plate 21. A glass plate 2 with spacers with sealing materials 22 and 24 formed by coating is used. Alternatively, the inner side of the peripheral edge of one surface of the glass plate 21 and the portion of the frame-shaped spacer 23 on which one side surface is disposed or the portion of the frame-shaped spacer 23 facing the glass plate 21 A glass plate 2 with a spacer with a sealing material 22 formed on a side surface by previously applying a sealing material is used.

上記したシール材２２、２４は、複層ガラスにおける一次シール材に該当するものであり、かかるシール材としては、スペーサ２３とガラス窓１およびガラス板２１との接着力が充分確保され、透湿防止性で、耐久性の高いブチルゴム系のシール材が最適である。
かかるスペーサ付きガラス板は、複層ガラス窓を施工する現場ではなく、別途工場にて生産管理が施された条件下で製造されるのが好ましい。 The sealing materials 22 and 24 described above correspond to the primary sealing material in the multi-layer glass, and as such a sealing material, sufficient adhesion between the spacer 23 and the glass window 1 and the glass plate 21 is ensured, and moisture permeability is ensured. A butyl rubber-based sealing material that is highly preventive and highly durable is optimal.
Such a glass plate with a spacer is preferably manufactured under conditions where production control is performed separately at a factory, not at the site where a multi-layer glass window is constructed.

スペーサ付きガラス板２のガラス板２１としては、通常、建築用として用いられているフロート板ガラス、普通ガラス板、熱線吸収ガラス板、紫外線吸収ガラス板、熱線反射ガラス板であってもよいが、複層ガラス窓の断熱性および遮熱性の向上のため、ガラス板２１のガラス窓１側の面に、Ｌｏｗ−Ｅ（Ｌｏｗ−Ｅｍｉｓｓｉｖｉｔｙ）膜が形成されたＬｏｗ−Ｅガラス板（低放射ガラス板）を使用するのが特に好ましい。また、型板ガラス、合わせガラス、線・網入りガラス板、倍強度ガラス、強化ガラス（風冷強化ガラス、化学強化ガラス）や、これらの機能が複合化されたガラス板などを、目的とする要求仕様に応じて適宜使用することができる。また、ガラス板２１の取り扱い中に、ガラス板２１が破損しないように、ガラス板２１の周縁部に面取り加工を施しておくことが好ましい。   The glass plate 21 of the glass plate 2 with a spacer may be a float plate glass, a normal glass plate, a heat ray absorbing glass plate, an ultraviolet ray absorbing glass plate, or a heat ray reflecting glass plate that is usually used for construction. Low-E glass plate (low emission glass plate) in which a Low-E (Low-Emissivity) film is formed on the surface of the glass plate 21 on the side of the glass window 1 in order to improve the heat insulation and heat shielding properties of the laminated glass window It is particularly preferred to use In addition, target glass, laminated glass, glass plate with wire / mesh, double-strength glass, tempered glass (air-cooled tempered glass, chemically tempered glass), and a glass plate that combines these functions It can be used appropriately according to the specification. Moreover, it is preferable to chamfer the peripheral edge of the glass plate 21 so that the glass plate 21 is not damaged during handling of the glass plate 21.

スペーサ２３としては、図１、２、５、６に示されるように、通常の複層ガラスにおいて使用されている断面が略角筒状のアルミニウム製のスペーサが使用される。略角筒状のアルミニウム製のスペーサの場合には、このスペーサの空間部の必要箇所には、複層ガラス窓の結露防止のための乾燥剤２６（例えば、シリカゲル等）が充填される。また、略角筒状のアルミニウム製のスペーサの場合には、その空間層２７となる側の内面部に、通気性の溝部２８を設けることが好ましい。この溝部は、スペーサの空間部と空間層２７との間を通気可能にするように形成されたものであり、通気孔を通してスペーサの空間部に充填された乾燥剤により空間層の乾燥状態を維持し、結露を低減できる。   As the spacer 23, as shown in FIGS. 1, 2, 5, and 6, an aluminum spacer having a substantially rectangular tube shape in cross section that is used in ordinary multilayer glass is used. In the case of a substantially square cylindrical aluminum spacer, a necessary portion of the spacer space is filled with a desiccant 26 (for example, silica gel or the like) for preventing condensation on the double-glazed glass window. Further, in the case of a substantially square cylindrical aluminum spacer, it is preferable to provide a breathable groove 28 on the inner surface on the side that becomes the space layer 27. This groove portion is formed so as to allow ventilation between the space portion of the spacer and the space layer 27, and the space layer is maintained in a dry state by a desiccant filled in the space portion of the spacer through the vent hole. And condensation can be reduced.

上記したスペーサ２３は、通常、矩形状のガラス板２１に対応した４辺（即ち、下辺側、左辺側、右辺側及び上辺側）を有する枠状となるように、下辺側、左辺側、右辺側及び上辺側の各スペーサのそれぞれが突き合わされる４つの角のコーナーにおいては、コーナーブロックを差し込み、それぞれのスペーサが連結される。
なお、乾燥剤は、例えば、矩形形状の多層ガラスのいずれか一辺のスペーサに充填してもよいし、複数辺のスペーサに充填してもよいし、また、一辺のスペーサの一部に部分的に充填してもよい。 The above-mentioned spacer 23 usually has a lower side, a left side, and a right side so as to have a frame shape having four sides corresponding to the rectangular glass plate 21 (that is, the lower side, the left side, the right side, and the upper side). At the corners of the four corners where each of the side and upper side spacers abut each other, a corner block is inserted to connect the spacers.
For example, the desiccant may be filled into a spacer on one side of a multilayer glass having a rectangular shape, or may be filled into a spacer on a plurality of sides, or partially on a part of the spacer on one side. May be filled.

（複層ガラス窓の組み立て方法）
複層ガラス窓の組立てを行うに当たっては、別途工場にて製作されたスペーサ付きガラス板２を、工場から複層ガラス窓の施工現場へ搬入する。次に、図１のように、シール材２４を介してスペーサ付きガラス板２をガラス窓１に取り付ける。図１は、ガラス窓１に対し、室内側からスペーサ付きガラス板２を取り付ける態様を示した例であるが、ガラス窓１に対し、室外側からスペーサ付きガラス板２を取り付ける態様としてもよい。
スペーサ付きガラス板２のガラス窓１への取り付けに当たっては、ガラス窓１の左右側の辺の所定箇所に位置決め用のガイドブロックを配するとともに、図３のように、スペーサ付きガラス板２の下辺側の所定箇所にセッティングブロック３６を配し、スペーサ付きガラス板２をガラス窓１に向かって（すなわち、図３における矢印方向）進行させ、スペーサ付きガラス板２をガラス窓１に対してシール材２４を介して圧着する。図示した例においては、セッティングブロック３６は、スペーサ付きガラス板２の下辺に間隔をあけて２個配置されている。なお、必要に応じて、左右の側辺側にもセッティングブロックを配してもよい。 (Assembly method of multi-layer glass window)
In assembling the multi-layer glass window, the glass plate 2 with a spacer manufactured separately at the factory is carried from the factory to the construction site of the multi-layer glass window. Next, as shown in FIG. 1, the glass plate 2 with the spacer is attached to the glass window 1 through the sealing material 24. FIG. 1 shows an example in which the glass plate 2 with spacers is attached to the glass window 1 from the indoor side, but the glass plate 2 with spacers may be attached to the glass window 1 from the outdoor side.
In attaching the glass plate 2 with a spacer to the glass window 1, a positioning guide block is arranged at a predetermined position on the left and right sides of the glass window 1, and the lower side of the glass plate 2 with a spacer as shown in FIG. A setting block 36 is arranged at a predetermined position on the side, the glass plate 2 with spacers is advanced toward the glass window 1 (that is, in the direction of the arrow in FIG. 3), and the glass plate 2 with spacers is sealed against the glass window 1 Crimp through 24. In the example shown in the figure, two setting blocks 36 are arranged at intervals on the lower side of the glass plate 2 with spacers. Note that setting blocks may be arranged on the left and right sides as necessary.

次いで、ガラス窓１に取り付けたスペーサ付きガラス板２の上下辺と左右辺とを押圧して圧着するとともに、後述する複層ガラス窓の施工用押え冶具を使用して、４つの隅部を同時、あるいは順次押し付けて圧着させる。
なお、スペーサ付きガラス板２をシール材２４を介してガラス窓１に取り付けた後、別途用意した押圧密着冶具によってスペーサ付きガラス板２の４辺を同時、あるいは順次押し付けて４辺を圧着させることもできる。 Next, the upper and lower sides and the left and right sides of the glass plate 2 with spacers attached to the glass window 1 are pressed and pressure-bonded, and the four corners are simultaneously formed using a presser jig for construction of a multi-layer glass window described later. Or, press them one after another to make them crimp.
In addition, after attaching the glass plate 2 with a spacer to the glass window 1 through the sealing material 24, the four sides of the glass plate 2 with the spacer are simultaneously or sequentially pressed by a separately prepared pressing and adhering jig to press the four sides. You can also.

必要に応じて、ガラス窓１に対してスペーサ付きガラス板２を取り付け、圧着して複層ガラス窓の組立て体を製造した後、ガラス窓１とスペーサ付きガラス板２との間の空間層２７を減圧し、次いで減圧された空間層２７にガスを注入してもよい。
また、スペーサ付きガラス板２とガラス窓１とが、シール材２４を介して充分圧着しているかどうかの圧着性の確認は、空間層２７の空気を吸い出して減圧状態を作り、空間層２７の間隔や圧力変化が無いことによって行なうことができる。 As needed, after attaching the glass plate 2 with a spacer to the glass window 1 and press-bonding it to produce a multilayer glass window assembly, the space layer 27 between the glass window 1 and the glass plate 2 with the spacer is used. May be decompressed, and then gas may be injected into the decompressed space layer 27.
In addition, to confirm whether or not the glass plate 2 with spacers and the glass window 1 are sufficiently crimped via the sealing material 24, the pressure of the space layer 27 is confirmed by sucking out the air in the space layer 27 and creating a reduced pressure state. This can be done without any interval or pressure change.

次に、図５に示すように、スペーサ付きガラス板の４辺近傍であって、スペーサ付きガラス板２の端部のガラス窓１側の間隙部４０に二次シール材が充填される。二次シール材としては、ガラスに対する接着性が高いシリコーン系シーラント、又はポリサルファイド系シーラントが使用される。また、二次シール材は染料又は顔料によって暗色系、例えば黒色に着色されているのが意匠上好ましい。更に、二次シール材は、スペーサ付きガラス板の４辺の外側に位置するガラス窓の枠状の面であって、スペーサ付きガラス板側に向いた面にも塗布されているのがより好ましい。なお、図５の（ａ）は、複層ガラス窓の下辺側部分の縦断面図を示し、図５の（ｂ）は、複層ガラス窓の上辺側部分の縦断面図を示す。
図６は、スペーサ付きガラス板２の端部のガラス窓１側の間隙部４０に二次シール材を充填した状態を示した複層ガラス窓の上辺側の概略図面であり、４１Ａは、スペーサ付きガラス板２の端部のガラス窓１側の間隙部４０に充填された二次シール材を示し、４１Ｂは、スペーサ付きガラス板の４辺の外側に位置するガラス窓の枠状の面であって、スペーサ付きガラス板側に向いた面にも塗布された二次シール材を示す。なお、同図は、複層ガラス窓の上辺側を例示した図面であるが、複層ガラス窓の下辺側も左右の側辺側も同様に二次シール材を形成することができる。 Next, as shown in FIG. 5, a secondary sealant is filled in the gap 40 on the side of the glass window 1 near the four sides of the glass plate with spacers and at the end of the glass plate 2 with spacers. As the secondary sealing material, a silicone sealant or a polysulfide sealant having high adhesion to glass is used. Moreover, it is preferable in terms of design that the secondary sealing material is colored in a dark color system, for example, black by a dye or a pigment. Furthermore, it is more preferable that the secondary sealing material is applied to the surface of the glass window located outside the four sides of the glass plate with spacers and facing the glass plate side with spacers. . 5A shows a longitudinal sectional view of the lower side portion of the multilayer glass window, and FIG. 5B shows a longitudinal sectional view of the upper side portion of the multilayer glass window.
FIG. 6 is a schematic view of the upper side of a multi-layer glass window showing a state in which the gap 40 on the glass window 1 side at the end of the glass plate 2 with a spacer is filled with a secondary sealing material. The secondary sealing material with which the gap | interval part 40 by the side of the glass window 1 at the edge part of the attached glass plate 2 was filled is shown, 41B is a frame-like surface of the glass window located in the outer side of four sides of the glass plate with a spacer. The secondary sealing material is also applied to the surface facing the glass plate with the spacer. In addition, although the figure is a figure which illustrated the upper side of the multilayer glass window, a secondary sealing material can be similarly formed on the lower side and the left and right sides of the multilayer glass window.

At this time, the first pedestal 51 and the second pedestal 52 are firmly positioned at the corners of the glass window 1 by the suction of the suction member 53.
Next, the knob 59 of the presser jig 50 is rotated to lower the adjustment shaft 57 to a predetermined position so that the glass presser plate 56 with the buffer member 67 is brought into contact with the corner of the glass plate 2 with the spacer. The glass plate 2 with a spacer is pressure-bonded to the glass window 1 while maintaining the attached state.
In addition, when constructing a multi-layer glass window, the reaction force of the force generated when the air layer of the constructed multi-layer glass window is depressurized, that is, the reaction force of the force that the glass plate with the spacer tries to elastically deform (with the spacer) The drag that prevents the elastic deformation of the glass plate) is transmitted to the holding jig, and the holding jig presses the corner surface of the glass plate with the spacer toward the glass window. Therefore, according to one aspect of the present invention, if four holding jigs are prepared and arranged at the four corners of the glass plate with spacers, the surfaces of the four corners of the glass plate with spacers are simultaneously pressed against the glass window. Can and is effective.
