上記車両において、さらに、内装材が、鉄道車両における屋根構体、側構体の少なくとも１つの内装パネルであり、波板の山または谷が連続する方向が鉄道車両の構体の胴まわり方向に向くように取付けられ、山または谷が連続する方向に湾曲またはおよび屈曲している構成では、鉄道車両の屋根構体、側構体、妻構体などにおける内装意匠の設計による湾曲形状や屈曲形状を生かして、山または谷が連続する方向を湾曲や屈曲の向きと直交するように設定することで、内装材の山および谷が繰り返す方向の曲げ剛性および座屈強度も高めることができ、従って、その方向の支持強度、被支持強度も増大し、化粧材支持構造および組立てのさらなる簡略化が図れる。[0016]
In the above vehicle, the interior material is at least one interior panel of a roof structure and a side structure of a rail car, and the mountain or valley of the corrugated sheet is attached such that the continuous direction of the mountain or valley is directed to the waist direction of the rail car structure. In a configuration where the mountains or valleys are curved or bent in the direction in which the mountains or valleys continue, the mountains or valleys take advantage of the curved shape or the bent shape by the design of the interior design in the roof structure, side structure, or end structure of the railway vehicle. By setting the direction in which the vertical direction is orthogonal to the direction of bending or bending, it is possible to increase the bending rigidity and buckling strength in the direction in which the peaks and valleys of the interior material repeat, thus supporting strength in that direction, The strength to be supported is also increased, and the cosmetic material support structure and assembly can be further simplified.

このように、金属製の波板４と金属製板５や金属製の内装用板５ａとを貼り合わせた上記のように支持強度および被支持強度、面外局部荷重に対する強度が増大し、しかも、簡単な構造の内装材１を複数の骨材７や内装支持部材８に亘る１枚ものとして通しで当てがい取付けることができるので、継ぎ目が少なく体裁のよい、また継ぎ目による強度や剛性の低下のない優れた内装ができる。しかも、前記支持強度、被支持強度、面外局部荷重に対する強度の高さから骨材７や内装支持部材８への取付け箇所は少なくて良く、車体の剛性上必要な骨材７があってもそれへの取付けを省略したり、骨材７が必要取付け箇所になかったり少なかったりして内装支持部材８を設けるにしてもその必要数を削減することができ、内装材１などを取付けのための構造および組み立てが簡単になるので車両コストの低減が図れる。内装材１は途中に屋根構体の軒桁などの骨７があってもそれに取付けなくてよいし、中間に内装支持部材８が従来あったような場合でもそれを省略することができる。[0034]
Thus, as described above in which the metal corrugated sheet 4 and the metal sheet 5 and the metal interior sheet 5a are bonded to each other, the support strength, the supported strength, and the strength against the out-of-plane local load increase. Since the interior material 1 having a simple structure can be properly fitted through as a single piece extending over a plurality of aggregates 7 and the interior support member 8, the joint has a small appearance, and the strength and the rigidity decrease due to the joint. Interior decoration can be done. Moreover, the location of attachment to the aggregate 7 or the interior support member 8 may be small because of the support strength, support strength, and strength against local load outside the surface, even if there is the aggregate 7 necessary for the rigidity of the vehicle body Even if the installation of the interior support member 8 is omitted by omitting the installation on it or when the aggregate 7 is not necessary or not at the required installation location, the required number can be reduced, and the installation of the interior material 1 etc. Thus, the cost and cost of the vehicle can be reduced. The interior material 1 does not have to be attached even if there is a bone 7 such as an eaves girder of the roof structure in the middle, and even if the interior support member 8 is conventionally located in the middle, it can be omitted.

天井パネル２１の両側部分をなす内装材１および側構体の内装パネルである内装材のそれぞれは、波板４の山４ａまたは谷４ｂが連続する方向が鉄道車両の構体の胴まわり方向に向くように取付けられ、内装材１は山４ａまたは谷４ｂが連続する方向に湾曲し、内装材２は山４ａまたは谷４ｂが連続する方向にまたはおよび屈曲していることにより、鉄道車両３の屋根構体、側構体などにおける内装意匠の設計による湾曲形状や屈曲形状を生かして、山４ａまたは谷４ｂが連続する方向を湾曲や屈曲の向きと直交するように設定することで、内装材１の山４ａおよび谷４ｂが繰り返す方向の曲げ剛性、座屈強度および面外局部荷重に対する強度も高めることができ、従って、その方向の支持強度、被支持強度も増大し、化粧材支持構造および組立てのさらなる簡略化が図れる。図示しないが妻構体、仕切り構体にも同様に適用することができる。[0036]
Each of the interior material 1 forming both side portions of the ceiling panel 21 and the interior material which is the interior panel of the side structure is such that the direction in which the mountain 4a or the valley 4b of the corrugated sheet 4 is continuous is directed to the waistline direction of the railway vehicle structure attached, the interior material 1 is curved in the direction of the mountain 4a or valley 4b are continuous, by the interior material 2 that direction or and bending mountain 4a or valley 4b are continuous, the roof structure of the railway vehicle 3, By setting the direction in which the mountain 4a or the valley 4b is continuous to be orthogonal to the direction of the curve or the bending by utilizing the curved shape or the bent shape by the design of the interior design in the side structure or the like, the mountain 4a of the interior material 1 and The flexural rigidity and buckling strength in the direction in which the valleys 4b repeat can also be enhanced, so that the support strength and supported strength in that direction are also increased, and the cosmetic material support structure and It attained further simplification of the stand. Although not shown, the present invention can be similarly applied to a wife structure and a partition structure.
