Definitions
- the present invention relates to a multilayer window structure.
- a multilayer window in which an air layer is provided between two transparent plates is known from the viewpoint of sound insulation and heat insulation (see Patent Document 1).
- Such a multi-layer window is supported by a frame material because of a large variation in pressure difference between the internal pressure and the external pressure of the air layer.
- a sealing material, a polymer film, or the like is loaded between the frame member and the multilayer window in order to make the air layer airtight.
- window plates are easily damaged or condensed.
- snow adheres to the bottom of the railway vehicle, but when this railway vehicle travels through a tunnel, upward airflow is generated, and stones around the railway track adhere to the snow under the railway vehicle. is there. In that case, the stone was rolled up by the rising air current and collided with the glass window plate, and the glass window plate was damaged.
- a method of sticking a scattering prevention film to the outside of the glass window plate has been adopted, but the glass window plate cannot be completely prevented from being damaged. Therefore, at present, a multi-layer window in which a glass window plate and a polycarbonate window plate are combined is widely used.
- Such a multi-layer window can be prevented from cracking due to the impact of stones by placing the polycarbonate window facing the outside of the vehicle, but dew condensation occurs between the glass window and the polycarbonate window. There was a problem that was likely to occur. In particular, in the case of a large multi-layer window used in a cold region, condensation is likely to occur due to a large temperature difference between inside and outside the vehicle. As a method for solving this, there is known a method in which a desiccant is disposed between one window plate and the other window plate (see Patent Document 2).
- spacers are provided between the glass window plate (one window plate) and the polycarbonate window plate (the other window plate) on the respective peripheral edges of the one window plate and the other window plate. It is arranged to extend along.
- a sealing material is disposed between the spacer and one of the window plates and between the spacer and the other window plate so that the spacer is integrated with the one window plate and the other window plate. It has become. With such a configuration, a sealed air layer is formed between one window plate and the other window plate.
- the spacer has a hollow ring shape and is filled with a drying material.
- a plurality of slit-shaped holes are formed in the side wall of the spacer on the air layer side, and the inside of the spacer communicates with the air layer.
- the inside of an air layer is dehumidified with a desiccant.
- the present invention has been made to solve the above-described problems, and an object of the present invention is to provide a multilayer window structure capable of preventing the occurrence of condensation between a pair of window plates.
- a multi-layer window structure includes: one window plate made of glass; and made of polycarbonate; both the width and width are smaller than the one window plate, and the thickness is 5 mm to 30 mm.

- the spacer is filled with a desiccant.
- the primary sealing material is preferably made of butyl rubber.
- the elasticity that extends in close contact with each peripheral edge of the one window plate and the other window plate and that closely contacts the peripheral edge of the spacer It is preferable to further have a secondary sealing material made of a body.
- a black paint film is formed on the peripheral edge of the other window plate on the air layer side.
- the center of the other window plate is the periphery of the other window plate under the condition of an air temperature of 18 ° C to 25 ° C. It is preferable to warp from the portion so as to protrude 0.1 mm to 3.0 mm toward the opposite side of the one window plate.
- the other window plate made of polycarbonate is formed smaller in both the width and width than the one window plate made of glass, so that the peripheral window when the other window plate thermally expands is formed. Strain width is reduced. Further, by forming the other window plate with a thickness of 5 mm to 30 mm, it is possible to prevent moisture from penetrating into the air layer. In addition, by setting the size of the primary sealing material to 0.5 mm or more and 6 mm or more in width, even if stress is applied to the primary sealing material due to thermal expansion of the other window plate, cracks in the primary sealing material And tearing can be prevented. Thus, moisture permeation through the other window plate and moisture permeation due to cracking or tearing of the primary sealing material can be prevented. As described above, the occurrence of condensation between one window plate and the other window plate can be prevented.
- the moisture in the air layer sealed by one window plate, the other window plate and the spacer can be removed by filling the spacer with the desiccant. Therefore, it is possible to more effectively prevent the occurrence of condensation between one window plate and the other window plate.
- the primary sealing material is made of butyl rubber, so that moisture can be prevented from passing through the primary sealing material.
- the primary sealing material even if stress is applied to the primary sealing material, it is difficult for cracks and tears to occur, so that it is possible to more effectively prevent the occurrence of condensation between one window plate and the other window plate.
- the secondary sealing material made of an elastic body extends in close contact with the other window plate and the peripheral edge of the one window plate, and in close contact with the peripheral edge of the spacer, thereby forming an air layer. The penetration of moisture into the inside can be prevented more effectively.
- the center of the other window plate is 0.1 mm to 3 mm on the opposite side of the one window plate from the peripheral portion of the other window plate.

The expansion / contraction width becomes larger than the conventional one.
- the peripheral portion of the other window plate 23 is distorted by thermal expansion, and even if stress is applied to the primary sealing material 33a, peeling or cracking is unlikely to occur. Therefore, the permeation
- butyl rubber is excellent in moisture resistance, moisture can be prevented from permeating through the primary sealing material 33a. Moreover, since butyl rubber is rich in elasticity, the primary sealing material 33a is not easily cracked or broken.
- the secondary sealing material 33 b made of an elastic body is disposed between one window plate 21 and the other window plate 23.
- the cross-sectional shape of the secondary sealing material 33b is a trapezoid
- the width on the one window plate 21 side is about 15 mm
- the width on the other window plate 23 side is about 13.5 mm
- the vertical dimension is about 8 mm.
- the secondary sealing material 33 b extends in close contact with the peripheral edges of the one window plate 21 and the other window plate 23, and is in close contact so as to surround the peripheral edge of the spacer 27. Thereby, each peripheral part of the primary sealing material 33a and the spacer 27 will be in the state covered with the secondary sealing material 33b.
- the first frame member 25 is a rectangular member made of, for example, an aluminum alloy, and each of the peripheral edges of the one window plate 21, the other window plate 23, and the secondary seal material 33 b. It is arranged so as to surround it.
- the cross section of the first frame member 25 is L-shaped, and an annular first frame portion 25a that overlaps the edge (step surface 23b) on the outer surface 23a side of the other window plate 23 via the second elastic body 31b.
- a second frame portion 25b extending from the outer peripheral end of the first frame portion 25a in a direction orthogonal to the one window plate 21.
- the first frame portion 25a of the first frame member 25 is disposed inside the outer plate 15a and the window holding portion 15f via a third elastic body 31c.
- a second elastic body 31 b is disposed between the first frame portion 25 a and the other window plate 23.
- a first elastic body 31a is disposed between the second frame portion 25b and one of the window plates 21.

- a unit 17 is configured.
- the second frame member 36 has a substantially L-shaped cross section and extends in the vertical direction along the outer plate 15a.
- the cross-sectional shape of the inner edge portion 36a of the second frame member 36 is about 20 mm in length, for example, and presses the inner surface 21a of one window plate 21 through a liner 39 made of a rubber plate.
- the cross-sectional shape of the outer edge portion 36b of the second frame member 36 is, for example, about 23 mm in length, and a silicon-based quaternary seal member 38 is loaded between the second frame portion 25b.
- the multi-layer window unit 17 has both the inner surface 21a of one window plate 21 and the outer surface 23a (step surface 23b) of the other window plate 23 by the second frame member 36 and the outer plate 15a. Pressed and held.
- the other window plate 23 made of polycarbonate is formed smaller in both the width and width than the one window plate 21 made of glass.
- the width of the distortion at the peripheral edge when the window plate 23 is thermally expanded is suppressed.
- the other window plate 23 by forming the other window plate 23 to have a thickness of 5 mm to 30 mm, which is thicker than the other conventional window plate, it is possible to prevent moisture from permeating into the air layer AR.
- the primary sealing material 33a is subjected to the thermal expansion of the other window plate 23. Even if stress is applied to the material 33a, the primary seal material 33a can be prevented from cracking or tearing. For this reason, the permeation

Even if the window plate 23 expands and contracts due to thermal expansion, the other window plate 23 does not warp inward (on the one window plate 21 side). Therefore, the heat of the outside air is not directly transmitted to the one window plate 21 through the other window plate 23, and it is possible to prevent the occurrence of condensation due to the close contact between the one window plate 21 and the other window plate 23.
- the black portion BK made of a black coating film is formed on the inner peripheral side of the other window plate 23 (on the one window plate 21 side), thereby deteriorating the primary sealing material 33a due to sunlight irradiation. Can be prevented. For this reason, it is possible to prevent the occurrence of cracks in the primary sealing material 33a and to prolong the service life.

Therefore, it is possible to prevent the occurrence of condensation between the one window plate 21 and the other window plate 23. Moreover, the crack and tearing of the primary sealing material 33a can be prevented by using butyl rubber having high stretchability as the material of the primary sealing material 33a. Therefore, it is possible to prevent the occurrence of condensation between one window plate 21 and the other window plate 23. By covering the respective peripheral portions of the primary sealing material 33a and the spacer 27 with the secondary sealing material 33b, it is possible to prevent moisture from permeating into the AR in the air layer.

これを解決する方法としては、一方の窓板と他方の窓板との間に乾燥材を配置するものが知られている(特許文献2参照)。
すなわち、(1)本発明の一態様に係る複層窓構造は、ガラスからなる一方の窓板と;ポリカーボネートからなり、前記一方の窓板よりも縦幅横幅ともに小さく、5mm~30mmの厚さで形成された他方の窓板と;前記一方の窓板および前記他方の窓板の各周縁に沿って延在するように配置され、前記一方の窓板および前記他方の窓板の間の空気層の側の側壁に孔を有する中空環状のスペーサと;前記一方の窓板および前記他方の窓板の各周縁に沿って延在するとともに、前記一方の窓板と前記スペーサのとの間、および、前記他方の窓板と前記スペーサのとの間に配置された、厚さ0.5mm以上かつ幅6mm以上の弾性体からなる一次シール材と;を具備する。
はじめに、本実施形態の複層窓構造20を適用する鉄道車両1の概略構成について説明する。図1に示すように、鉄道車両1の車両構体2は、屋根構体3と一対の側構体5と台枠7と妻構体9と、から概略構成されている。これらのうち、台枠7は床部を構成し、台枠7の両側部には各側構体5が接合されている。屋根構体3には、車室内の冷暖房を行うためのエアコンディショナーやパンタグラフが据え付けられている。
次いで、本実施形態の複層窓構造20について説明する。図2に窓枠パネル15を外側から見た正面図、図3に図2のA-A線に沿った断面図、図4に図2のB-B線に沿った断面図、図5に図4の部分拡大図を示す。複層窓構造20は、窓枠パネル15と複層窓ユニット17から概略構成されている。以下、それぞれについてその詳細を説明する。
図1,2に示すように、窓枠パネル15は、車両構体2の外側に配置される外板15aと、車両構体2の内側に配置される内板15bと、これら外板15a及び内板15b間に設けられたリブ部15cと、から概略構成されている。このうち、図2に示すように、外板15aには、略矩形の窓開口Rが形成されている。さらに、図3,4に示すように、外板15aには、窓開口Rの縁に沿うように延在する、矩形で且つ環状の窓保持部15fが設けられている。
図2,4に示すように、窓押え金41、部材40aおよび外板15aには、2箇所にボルト40を通す孔15hが設けられている。窓押え金41は、ボルト40の締め付けにより、部材40a、外板15a(窓保持部15f)、第三の弾性体31c、第1の枠部25aおよび第二の弾性体31bを介して他方の窓板23を車両内側方向に押圧する。
図2に示すように、クランプ台34は、複層窓ユニット17の上端部および下端部に沿って水平に延在する。なお、クランプ台34はその延在方向に垂直な断面で見た場合に略U字状であり、その端部は窓枠パネル15に溶接されている。
図3,4に示すように、複層窓ユニット17は、一方の窓板21と、他方の窓板23と、スペーサ27と、一次シール材33aと、二次シール材33bと、第一の枠材25と、を備えている。複層窓ユニット17は、正面視した場合に、たとえば略矩形であり、窓開口Rを塞ぐようにして装着されている。
一方の窓板21は、たとえば縦986mm×横2036mm×厚さ4mm程度の、略矩形状を有する透明なガラスである。一方の窓板21は、他方の窓板23と対向するように配置され、鉄道車両1に複層窓構造20を装着する際、車両内側に設置される。
他方の窓板23は、たとえば縦984mm×横2033mm×厚さ8mm程度の、透明なポリカーボネートからなる略矩形の窓板である。他方の窓板23は、鉄道車両1に複層窓構造20を装着する際、車両外側に設置される。
また、他方の窓板23は、一方の窓板21に対し、たとえば8mm程度離間して配置されており、互いの間には密閉された空気層ARが形成されている。
図5に示すように、スペーサ27は、たとえば断面形状が縦7mm×横7mm程度の中空環状であり、一方の窓板21および他方の窓板23の間に配置されている。スペーサ27は、一次シール材33aを介して一方の窓板21および他方の窓板23に接着されており、一方の窓板21および他方の窓板23の周縁に沿って延在している。これにより、スペーサ27、一方の窓板21および他方の窓板23は一体化し、一方の窓板21および他方の窓板23の間に空気層ARを形成している。
図5に示すように、一次シール材33aは、一方の窓板21とスペーサ27との間、他方の窓板23とスペーサ27との間にそれぞれ1本ずつが配置されている。一次シール材33aは弾性体からなり、一方の窓板21および他方の窓板23の周縁に沿って延在するとともに、スペーサ27の側面に密着している。このような構成により、スペーサ27、一方の窓板21および他方の窓板23は一体化されている。
図5に示すように、弾性体からなる二次シール材33bは、一方の窓板21および他方の窓板23の間に配置されている。また、二次シール材33bの断面形状は台形であり、一方の窓板21側の横幅が15mm程度、他方の窓板23側の横幅が13.5mm程度、縦寸法が8mm程度となっている。また、二次シール材33bは、一方の窓板21および他方の窓板23の周縁に密着して延在するとともに、スペーサ27の周縁を取り囲むように密着している。これにより、一次シール材33aとスペーサ27の各周縁部は、二次シール材33bによって覆われた状態となる。
図3,4に示すように、第一の枠材25は、たとえばアルミニウム合金からなる矩形状の部材であり、一方の窓板21、他方の窓板23および二次シール材33bの各周縁を取り囲むように配置されている。第一の枠材25の断面はL字状であり、他方の窓板23の外面23a側の縁(段差面23b)に第二の弾性体31bを介して重なり合う環状の第1の枠部25aと、第1の枠部25aの外周端から一方の窓板21に直交する方向に延在する第2の枠部25bと、から構成されている。
また、他方の窓板23の内側(一方の窓板21側)の周縁部に、黒色の塗膜からなる黒色部BKが形成されていることにより、日光の照射による一次シール材33aの劣化を防ぐことができる。そのため、一次シール材33aの亀裂発生を防ぐことができるとともに、耐用期間を長くすることが可能となる。
また、一次シール材33aの材料として、伸縮性に富むブチルゴムを用いることにより、一次シール材33aの亀裂や断裂が防げる。そのため、一方の窓板21と他方の窓板23との間の結露発生を防ぐことができる。
一次シール材33aとスペーサ27の各周縁部を二次シール材33bによって覆うことにより、空気層中ARへの水分の透過を防ぐことができる。また、二次シール材33bによりスペーサ27の周縁側を支持することにより、一次シール材33aの亀裂や断裂を防ぐことができる。これにより、一方の窓板21と他方の窓板23との間の結露発生を防ぐことができる。
以上により、一方の窓板21と他方の窓板23との間の結露発生を防ぐことができる。
(実施例1)
一方の窓板21とスペーサ27との間、他方の窓板23とスペーサ27との間には、断面形状が厚さ0.5mm、幅6mmのブチルゴムからなる一次シール材33aをそれぞれ配置し、スペーサ27、一方の窓板21および他方の窓板23を一体化させた。また、スペーサ27の周縁部の一方の窓板21および他方の窓板23の間には、ブチルゴムからなる二次シール材33bを配置した。
