The side film 21 is fixed in such a manner that it is gripped in the gap between the rising duct 70 (including the overhanging portion 70a) and the first window kiss 71.

図７に示すように、第１窓キセ７１の車内側には、テーブル７３や調和空気の吐出し口および流路などを備える第２窓キセ７２が備えられる。第２窓キセ７２を備える第１窓キセ７１は、キセモジュール７６を構成する。立ち上がりダクト７０を含むダクトモジュール７７（図６）は、側膜２１の車外側に備えられる断熱材（吸音材、遮音材を兼ねると好ましい）７４（後述する図８参照）の表面に側膜２１を押圧するキセモジュール７６を支持するに十分な剛性を有する。 As shown in FIG. 7, inside the vehicle of the first window kiss 71, a second window kiss 72 including a table 73, a discharge port for conditioned air, a flow path, and the like is provided.

図８はダクトモジュールおよびキセモジュールの高さ方向に交差する断面図（図６のＣ－Ｃ断面図）であり、図９はダクトモジュールおよびキセモジュールを鉄道車両に取り付ける際の作業手順を示す模式図である。 FIG. 8 is a cross-sectional view (CC cross-sectional view of FIG. 6) intersecting the duct module and the xet module in the height direction, and FIG. It is a figure.

以下、ダクトモジュールおよびキセモジュールを鉄道車両に取り付ける際の作業について説明する。まず、台枠１０と側構体２０と屋根構体３０などからなる６面体の構体７が製造される。図９において、側構体２０および屋根構体３０の車内側には断熱材７４が貼りつけられ（矢印７９ａ）、この断熱材７４の車内側にダクトモジュール７７（立ち上がりダクト７０）が固定される（矢印７９ｂ）。ダクトモジュール７７が車内側に傾かないように、必要に応じて、ダクトモジュール７７のＺ方向の中央部と側構体２０とを接続しても良い。 Hereinafter, the work for attaching the duct module and the skein module to the railroad vehicle will be described. First, a hexahedral structure 7 including an underframe 10, a side structure 20, a roof structure 30, and the like is manufactured. In FIG. 9, a heat insulating material 74 is attached to the inside of the vehicle of the side structure 20 and the roof structure 30 (arrow 79a), and the duct module 77 (rising duct 70) is fixed to the inside of the vehicle of the heat insulating material 74 (arrow). 79b). If necessary, the central portion of the duct module 77 in the Z direction and the side structure 20 may be connected so that the duct module 77 does not tilt inward of the vehicle.

続いて、側膜２１を側構体２０に備える過程で、この側膜２１により立ち上がりダクト７０を車内側から覆う（矢印７９ｃ）。更に、立ち上がりダクト７０に対して、車内側から側膜２１を車外の方向へ押圧する態様で、キセモジュール７６を立ち上がりダクト７０に固定する（矢印７９ｄ）。 Subsequently, in the process of providing the side film 21 to the side structure 20, the rising duct 70 is covered from the inside of the vehicle by the side film 21 (arrow 79c). Further, the kiss module 76 is fixed to the rising duct 70 in a manner of pressing the side film 21 from the inside of the vehicle toward the outside of the vehicle against the rising duct 70 (arrow 79d).

従来は、鉄道車両１の構体７を構成する側構体２０の車内側に、複数の窓２３に対応する側内装材を備え、同様に、屋根構体３０の車内側に複数の天井内装材を備えていた。これに対し、本実施形態の構成によれば、一連の窓２３を含む側構体２０の車内側をＸ方向に単一材である側膜２１で覆うとともに、屋根構体３０の車内側を単一材である（図１の例では２つの）天井膜３１で覆うので、内装材に関する部品点数を大幅に低減することができる。 Conventionally, side interior materials corresponding to a plurality of windows 23 are provided inside the side structure 20 constituting the structure 7 of the railway vehicle 1, and similarly, a plurality of ceiling interior materials are provided inside the roof structure 30. Was there. On the other hand, according to the configuration of the present embodiment, the inside of the side structure 20 including the series of windows 23 is covered with the side film 21 which is a single material in the X direction, and the inside of the roof structure 30 is single. Since it is covered with the ceiling film 31 (two in the example of FIG. 1), which is a material, the number of parts related to the interior material can be significantly reduced.

さらに、従来における窓に対応して配置される複数の側内装材は、一旦、取付けて取付状況を確認した後、必要に応じて取り外して、間隔や隙間を調整する作業などが含まれることから、隣り合う側内装材との位置決め作業に多くの工数を要していた。同様に複数の天井内装材も、隣り合う天井内装材の位置決めに多くの工数を要していた。これに対し、本実施形態の構成によれば、側膜２１および天井膜３１を架け渡すように配置することで、側内装材および天井内装材に係わる位置決め工数を大幅に削減することができる。 Furthermore, since the plurality of side interior materials arranged corresponding to the conventional windows include work such as once mounting, checking the mounting status, and then removing as necessary to adjust the intervals and gaps. , It took a lot of man-hours to position the interior material on the adjacent side. Similarly, for a plurality of ceiling interior materials, a large number of man-hours are required for positioning adjacent ceiling interior materials. On the other hand, according to the configuration of the present embodiment, by arranging the side film 21 and the ceiling film 31 so as to bridge each other, the positioning man-hours related to the side interior material and the ceiling interior material can be significantly reduced.

さらに、側膜２１および天井膜３１の単位面積当たりの重量が、従来の熱可塑性樹脂などからなる側内装材および天井内装材の重量に比較して小さいので、大幅な軽量化を実現できる。さらに、側膜２１および天井膜３１で軽量化した重量の一部を利用して、車両全体の重量を大きくすることなく、より面密度の大きい遮音材（吸音材）や断熱材を採用することによって、車内騒音が小さくより快適な移動空間を提供することができる。 Further, since the weight per unit area of the side film 21 and the ceiling film 31 is smaller than the weight of the side interior material and the ceiling interior material made of a conventional thermoplastic resin or the like, a significant weight reduction can be realized. Further, by utilizing a part of the weight reduced by the side membrane 21 and the ceiling membrane 31, a sound insulating material (sound absorbing material) or a heat insulating material having a higher surface density is adopted without increasing the weight of the entire vehicle. Therefore, it is possible to provide a more comfortable moving space with less noise in the vehicle.

また、従来、鉄道車両１の車内で生じる騒音は、側内装材および天井内装材の車内側の面で反射するため減衰率が小さく、車内騒音の低減を阻害していた。これに対し本実施の形態によれば、可撓性のある側膜２１および天井膜３１が鉄道車両１の車内の大部分を覆うため、反射に伴う車内騒音の減衰率が大きくなり車内騒音の低減を促進することができる。 Further, conventionally, the noise generated in the vehicle of the railway vehicle 1 is reflected on the inner surface of the side interior material and the ceiling interior material, so that the attenuation rate is small, which hinders the reduction of the noise in the vehicle. On the other hand, according to the present embodiment, since the flexible side film 21 and the ceiling film 31 cover most of the inside of the railroad vehicle 1, the attenuation rate of the in-vehicle noise due to the reflection becomes large, and the in-vehicle noise becomes large. Reduction can be promoted.

以上述べたように、本実施形態によれば、部品点数を削減するとともに、側構体および屋根構体と内装材との位置決め作業に係わる製作工数を低減でき、軽量な内装材を有する鉄道車両を提供することができる。 As described above, according to the present embodiment, it is possible to reduce the number of parts and the manufacturing man-hours related to the positioning work between the side structure and the roof structure and the interior material, and provide a railway vehicle having a lightweight interior material. can do.
