　次に、発明の実施の形態を説明する。
　まず始めに、電磁波遮蔽性能を有する合わせガラスの構成について、図１を用いて説明する。
　図１に示す如く、合わせガラス１は、電磁波遮蔽性能を有する合わせガラスであり、一対のガラス板２・３の間に、中間膜４・５および導電性部材６を介在させている。 Next, embodiments of the invention will be described.
First, the structure of a laminated glass having electromagnetic wave shielding performance will be described with reference to FIG.
As shown in FIG. 1, the laminated glass 1 is a laminated glass having electromagnetic wave shielding performance, and an intermediate film 4, 5 and a conductive member 6 are interposed between a pair of glass plates 2, 3.
　一対のガラス板２・３は、透明なフロートガラスであり、互いに平行に配置するとともに、軟化した中間膜４・５により接着されることによって、一対のガラス板２・３の間に導電性部材６を介在させつつ一体化される。 The pair of glass plates 2 and 3 are transparent float glass, arranged in parallel to each other, and bonded to each other by the softened intermediate films 4 and 5 so that a conductive member is interposed between the pair of glass plates 2 and 3. 6 is integrated.
　中間膜４・５は、樹脂製の膜状部材であり、一対のガラス板２・３の間に導電性部材６とともに配置される。中間膜４・５は、加熱により軟化させることによって、導電性部材６を介在させつつ、一対のガラス板２・３を接着する役割を果たす部材であり、本実施形態ではＥＶＡ（エチレン・酢酸ビニル共重合樹脂）製としている。尚、中間膜４・５としては、ＰＶＢ（ポリビニルブチラール樹脂）製のものを採用することも可能である。 The intermediate films 4 and 5 are resin-made film-like members, and are disposed together with the conductive member 6 between the pair of glass plates 2 and 3. The intermediate films 4 and 5 are members that play a role of bonding the pair of glass plates 2 and 3 while interposing the conductive member 6 by being softened by heating. In this embodiment, EVA (ethylene / vinyl acetate) is used. Copolymer resin). The intermediate films 4 and 5 may be made of PVB (polyvinyl butyral resin).
　導電性部材６は、樹脂製（例えば、ＰＥＴ製）のメッシュシートを基材として、該メッシュの表面に導電性材料（例えば、Ｃｕ）をコーティングして構成される部材であり、一対のガラス板２・３の間において、中間膜４・５とともに配置される。
　より詳しくは、合わせガラス１では、ガラス板２と導電性部材６の間に中間膜４が配置され、ガラス板３と導電性部材６の間に中間膜５が配置される。
　尚、本実施形態で示す導電性部材６は、Ｃｕの表面にさらに黒鉛を塗布したものを採用している。 The conductive member 6 is a member configured by coating a mesh material made of resin (for example, PET) as a base material and coating the surface of the mesh with a conductive material (for example, Cu), and a pair of glass plates 2 and 3 are arranged together with the intermediate films 4 and 5.
More specifically, in the laminated glass 1, the intermediate film 4 is disposed between the glass plate 2 and the conductive member 6, and the intermediate film 5 is disposed between the glass plate 3 and the conductive member 6.
In addition, the electroconductive member 6 shown by this embodiment employ | adopted what further apply | coated graphite on the surface of Cu.
　そして、合わせガラス１の導電性部材６は、一対のガラス板２・３の周囲から食み出した部位である食み出し部６ａを備えている。
　食み出し部６ａは、合わせガラス１を窓枠等に設置する際に、該合わせガラス１の周囲に配置される接地体（図示せず）に対して接続される部位であり、食み出し部６ａを接地体に接続することによって、合わせガラス１の電磁波遮蔽性能が発揮される。 And the electroconductive member 6 of the laminated glass 1 is provided with the protrusion part 6a which is the site | part which protruded from the circumference | surroundings of a pair of glass plates 2 * 3.
The protruding portion 6a is a portion connected to a grounding body (not shown) arranged around the laminated glass 1 when the laminated glass 1 is installed on a window frame or the like. By connecting the part 6a to the grounding body, the electromagnetic wave shielding performance of the laminated glass 1 is exhibited.
　導電性部材６は、光を透過する性質を有しており、一対のガラス板２・３の間に導電性部材６を介在させた合わせガラス１は、光を透過しつつ（透視性を有しつつ）、電磁波を遮蔽する能力を有する。 The conductive member 6 has a property of transmitting light, and the laminated glass 1 in which the conductive member 6 is interposed between the pair of glass plates 2 and 3 transmits light (has transparency). However, it has the ability to shield electromagnetic waves.
　導電性部材６は、食み出し部６ａが折り曲げられることによって、メッシュの表面に付着している導電性材料（Ｃｕ）が剥がれたり、あるいは、メッシュを構成する繊維が断線したりすると、導電性が低下し、ひいては、合わせガラス１の電磁波遮蔽性能が低下する要因となる。このため、合わせガラス１は、導電性部材６の食み出し部６ａを、折り曲げずに製造することが望まれる。 When the protruding portion 6a is bent, the conductive member 6 becomes conductive when the conductive material (Cu) attached to the surface of the mesh is peeled off or the fibers constituting the mesh are disconnected. As a result, the electromagnetic wave shielding performance of the laminated glass 1 is reduced. For this reason, the laminated glass 1 is desired to be manufactured without bending the protruding portion 6a of the conductive member 6.

As shown in FIG. 2, the protective member 10 used in the method for manufacturing a laminated glass 1 according to an embodiment of the present invention is composed of a pair of plate- like members 11 and 12.
　第一の板状部材１１は、合わせガラス１の製造時において、導電性部材６の食み出し部６ａを下方から支持するとともに、食み出し部６ａの裏面（下面）を保護するためのアルミニウム製の部材であり、その厚みが、ガラス板２と中間膜４の厚みの合計と略一致している。

The thickness of the glass plate 2 and the intermediate film 4 is approximately equal to the total thickness of the glass plate 2 and the intermediate film 4.
Moreover, as shown to FIG. 3 (A), the 1st plate-shaped member 11 is formed in a series of frame-shaped bodies provided with the hole part 11a, and the glass plate 2 and intermediate | middle are formed in the hole part 11a. It is comprised so that the film | membrane 4 can be arrange | positioned.

　また、第二の板状部材１２は、図３（Ａ）に示すように、孔部１２ａを備えた一連の枠状体に形成されており、孔部１２ａの中に、ガラス板３および中間膜５を配置することができるように構成されている。 The 2nd plate-shaped member 12 is a member made from aluminum for protecting the surface (upper surface) of the protrusion part 6a of the electroconductive member 6 at the time of manufacture of the laminated glass 1, The thickness is a glass plate. 3 and the total thickness of the intermediate film 5 substantially coincide with each other.
Further, as shown in FIG. 3A, the second plate-like member 12 is formed in a series of frame-like bodies provided with holes 12a, and the glass plate 3 and the middle are formed in the holes 12a. It is comprised so that the film | membrane 5 can be arrange | positioned.

　第一の板状部材１１は、孔部１１ａの角部が、導電性部材６に接触することとなるため、該角部において、面取り部１１ｂが形成されている。第一の板状部材１１の角部に、面取り部１１ｂを形成することによって、真空引きの際に、第一の板状部材１１と導電性部材６が接触しても、導電性部材６の下面に傷が付くことを防止できる。 The first plate-like member 11 has a chamfered portion 11b formed at the corner portion because the corner portion of the hole portion 11a comes into contact with the conductive member 6.

　また、第二の板状部材１２は、孔部１２ａの角部が、導電性部材６に接触することとなるため、該角部において、面取り部１２ｂが形成されている。第二の板状部材１２の角部に、面取り部１２ｂを形成することによって、真空引きの際に、第二の板状部材１２と導電性部材６が接触しても、導電性部材６の上面に傷が付くことを防止できる。 Moreover, since the corner | angular part of the hole 12a contacts the electroconductive member 6 in the 2nd plate-shaped member 12, the chamfered part 12b is formed in this corner | angular part. By forming the chamfered portion 12b at the corner of the second plate-like member 12, even if the second plate-like member 12 and the conductive member 6 come into contact with each other at the time of vacuuming, the conductive member 6 It is possible to prevent the upper surface from being scratched.
　尚、本実施形態では、食み出し部６ａを保護するための保護部材１０を、板状部材１１・１２で構成した場合を例示しているが、保護部材の構成はこれに限定されない。本発明の一実施形態に係る合わせガラス１の製造方法において使用する保護部材は、例えば、塊状の弾性体で食み出し部６ａを覆って保護する構成や、綿状の部材で食み出し部６ａを覆って保護する構成等も採用することができ、真空バッグ２０の収縮時において、食み出し部６ａに作用する応力を抑止および軽減して、食み出し部６ａの破損を防止できる種々の構成を採用し得る。 In addition, in this embodiment, although the case where the protective member 10 for protecting the protrusion part 6a is comprised by the plate-shaped members 11 * 12 is illustrated, the structure of a protective member is not limited to this. The protective member used in the manufacturing method of the laminated glass 1 which concerns on one Embodiment of this invention is the structure which covers and protects the protrusion part 6a with a lump-shaped elastic body, for example, and a protrusion part with a cotton-like member The structure which covers and protects 6a can also be adopted, and when the vacuum bag 20 is contracted, the stress acting on the protruding portion 6a can be suppressed and reduced to prevent the protruding portion 6a from being damaged.

　また、保護部材１０は、できるだけ軽量の素材を用いて構成することが好ましく、より軽い保護部材１０を用いることによって、合わせガラス１の製造作業（より詳しくは、保護部材１０の配置作業）における作業者の負担を軽減することができる。 Moreover, although the protection member 10 (each plate-shaped member 11 * 12) shown by this embodiment is made from aluminum, the material of the protection member 10 is not limited to this, The heating temperature (about about at the time of manufacture of the laminated glass 1) 150.degree.

By using the lighter protective member 10, a work in manufacturing the laminated glass 1 (more specifically, an operation of arranging the protective member 10). The burden on the user can be reduced.
　さらに、本実施形態では、第一の板状部材１１および第二の板状部材１２に形成する各面取り部１１ｂ・１２ｂを、Ｒ面取りとした場合を例示しているが、保護部材１０に形成する面取りの態様はこれに限定されず、例えば、Ｃ面取りであってもよく、導電性部材６との接触部に角部を残さない態様となっていればよい。 Furthermore, in this embodiment, although the case where each chamfering part 11b * 12b formed in the 1st plate-shaped member 11 and the 2nd plate-shaped member 12 is made into R chamfering is illustrated, it forms in the protection member 10 The chamfering aspect to perform is not limited to this, For example, C chamfering may be sufficient as long as it does not leave a corner | angular part in a contact part with the electroconductive member 6.

　各板状部材１１・１２を一連の枠状体の形態とした場合、板状部材１１・１２には、各板状部材１１・１２の外部と各孔部１１ａ・１２ａが連通される隙間が無いため、真空バッグ２０（図２参照）内で真空引きする際に、各板状部材１１・１２の周囲における真空バッグ２０の食い込みを軽減することができ、合わせガラス１の加工を安定させることができる。 Moreover, in the manufacturing method of the laminated glass 1 which concerns on one Embodiment of this invention, as shown to FIG. 3 (A), the shape of each plate-shaped member 11 * 12 is made into the hole part 11a * surrounding glass plate 2.3 *. It is preferable to form a series of frame-like bodies formed with 12a.

　図８および図９に示す如く、本発明の別実施形態に係る合わせガラス１００の製造方法は、まず始めに、保護部材１１０を構成する第一の板状部材１１１を、定盤や作業床上の所定位置に配置する（ＳＴＥＰ－２０１）。 Next, the flow of the manufacturing method of the laminated glass 100 for electromagnetic wave shielding which concerns on another embodiment of this invention is demonstrated.
As shown in FIGS. 8 and 9, in the method for manufacturing a laminated glass 100 according to another embodiment of the present invention, first, the first plate member 111 constituting the protective member 110 is placed on a surface plate or a work floor. It is arranged at a predetermined position (STEP-201).
　次に、第一の板状部材１１１の配置位置を基準として、第一の板状部材１１１の孔部１１１ａの中で、下段のガラス板１０１、中間膜１０４の順に積層していき、孔部１１１ａから食み出し部１０６ａが形成されるように導電性部材１０６を被せた後、さらに中間膜１０５、中段のガラス板１０２の順に積層する（ＳＴＥＰ－２０２）。 Next, on the basis of the arrangement position of the first plate-like member 111, the lower glass plate 101 and the intermediate film 104 are sequentially laminated in the hole 111a of the first plate-like member 111. After covering the conductive member 106 so that the protruding portion 106a is formed from 111a, the intermediate film 105 and the middle glass plate 102 are laminated in this order (STEP-202).
　次に、中段のガラス板１０２および中間膜１０５を孔部１１２ａに通しつつ、導電性部材１０６の食み出し部１０６ａを、第一の板状部材１１１との間で挟むように、第二の板状部材１１２を重ねて配置する（ＳＴＥＰ－２０３）。
　尚、本実施形態では、中段のガラス板１０２および中間膜１０５を配置した後に、第二の板状部材１１２を配置する構成としているが、例えば、第二の板状部材１１２を所定位置に配置した後に、孔部１１２ａを基準として、孔部１１２ａの中にガラス板１０２および中間膜１０５を配置してもよい。 Next, the second glass plate 102 and the intermediate film 105 are passed through the hole portion 112a while the protruding portion 106a of the conductive member 106 is sandwiched between the first plate member 111 and the second plate portion 111a. The plate-like members 112 are stacked and placed (STEP-203).
In this embodiment, the second plate member 112 is arranged after the middle glass plate 102 and the intermediate film 105 are arranged. For example, the second plate member 112 is arranged at a predetermined position. After that, the glass plate 102 and the intermediate film 105 may be disposed in the hole 112a with the hole 112a as a reference.
　次に、中段の板ガラス１０２に対して中間膜１０７を積層していき、食み出し部１０９ａが形成されるように導電性部材１０９を被せた後、さらに中間膜１０８、上段のガラス板１０３の順に積層して、積層体１２０を形成する（ＳＴＥＰ－２０４）。 Next, the intermediate film 107 is laminated on the middle plate glass 102, and after covering the conductive member 109 so that the protruding portion 109a is formed, the intermediate film 108 and the upper glass plate 103 are further formed. By sequentially laminating, the laminate 120 is formed (STEP-204).
　次に、上段のガラス板１０３および中間膜１０８を孔部１１３ａに通しつつ、導電性部材１０９の食み出し部１０９ａを、第二の板状部材１１２との間で挟むように、第三の板状部材１１３を重ねて配置する（ＳＴＥＰ－２０５）。
　このようにして、２層の食み出し部１０６ａ・１０９ａを、保護部材１１０によって保護する。
　尚、本実施形態では、上段のガラス板１０３および中間膜１０８を配置した後に、第三の板状部材１１３を配置する構成としているが、例えば、第三の板状部材１１３を所定位置に配置した後に、孔部１１３ａを基準として、孔部１１３ａの中にガラス板１０３および中間膜１０８を配置してもよい。 Next, while passing the upper glass plate 103 and the intermediate film 108 through the hole 113a, the protruding portion 109a of the conductive member 109 is sandwiched between the second plate member 112 and the third plate 112. The plate-like members 113 are arranged so as to overlap each other (STEP-205).
In this manner, the two layers of the protruding portions 106a and 109a are protected by the protective member 110.
In the present embodiment, the third plate member 113 is arranged after the upper glass plate 103 and the intermediate film 108 are arranged. For example, the third plate member 113 is arranged at a predetermined position. After that, the glass plate 103 and the intermediate film 108 may be disposed in the hole 113a with the hole 113a as a reference.
　次に、導電性部材１０６・１０９の食み出し部１０６ａ・１０９ａを保護部材１１０で覆った状態で積層体１２０を真空バッグ２０に入れて、真空バッグ２０内の真空引きを行い、積層体１２０内の滞留している余分な空気を除去した後に、積層体１２０を保護部材１１０ごとオートクレーブ容器内で加圧、加熱して、中間膜１０４・１０５・１０７・１０８を軟化させ、積層体１２０の各層を一体化させることによって合わせガラス１００を作製する（ＳＴＥＰ－２０６）。 Next, the laminated body 120 is put in the vacuum bag 20 in a state where the protruding portions 106a and 109a of the conductive members 106 and 109 are covered with the protective member 110, and the vacuum bag 20 is evacuated to laminate the laminated body 120. After removing excess air remaining in the laminate, the laminate 120 is pressurized and heated in the autoclave container together with the protective member 110 to soften the intermediate films 104, 105, 107, and 108, and The laminated glass 100 is produced by integrating the layers (STEP-206).
　そして冷却後に、合わせガラス１００を真空バッグ２０から取り出し、保護部材１１０を除去することによって、合わせガラス１００が得られる。 Then, after cooling, the laminated glass 100 is taken out from the vacuum bag 20 and the protective member 110 is removed, whereby the laminated glass 100 is obtained.
　合わせガラス１００は、食み出し部１０６ａ・１０９ａを保護部材１１０で保護しながら真空引き等の処理が施されるため、食み出し部１０６ａ・１０９ａは、真空バッグ２０が収縮する際に折り曲げられてしまうことがなく、導電性部材１０６・１０９の層数が増えた場合であっても、真空引きが終了するまで良好な（曲がりのない）形状を維持することができる。そのため、合わせガラス１００において所望する導電性を確実に確保することができ、電磁波遮蔽性能の向上を図ることができる。 The laminated glass 100 is subjected to a process such as evacuation while protecting the protruding portions 106a and 109a with the protective member 110. Therefore, the protruding portions 106a and 109a are bent when the vacuum bag 20 contracts. Even when the number of layers of the conductive members 106 and 109 is increased, a good shape (without bending) can be maintained until the evacuation is completed. Therefore, the desired conductivity in the laminated glass 100 can be reliably ensured, and the electromagnetic wave shielding performance can be improved.

The conductive member 109 is formed around the conductive member 109. Further, a protruding portion 109a, which is a portion where the conductive member 109 protrudes from the intermediate films 107 and 108, is formed. The conductive member 106 and the intermediate films 104 and 105 are disposed between the plates 101 and 102, and the conductive member 109 is disposed between the adjacent glass plates 102 and 103 of the three glass plates 101, 102, and 103.
