Description

本発明は、シングルスキンタイプの外板を有し、外板に内側配置材との溶接接合部を持った鉄道車両構体に関するものである。   The present invention relates to a railway vehicle structure having a single skin type outer plate and having a welded joint with an inner arrangement member on the outer plate.

外板には通常、鋼板、ステンレス鋼板、アルミニウム板が用いられ、特に、鋼板、ステンレス鋼板では内側配置材としての骨材などとの溶接接合部を有している。溶接方法はスポット溶接やレーザ溶接が採用されている(例えば、特許文献1、2参照。)。   A steel plate, a stainless steel plate, and an aluminum plate are usually used for the outer plate. Particularly, the steel plate and the stainless steel plate have a welded joint portion with an aggregate as an inner arrangement member. Spot welding or laser welding is employed as the welding method (see, for example, Patent Documents 1 and 2).

特許文献2はスポット溶接の場合電極の押圧による圧痕や大電流を通すことによる高温酸化が原因した変色が生じるとし、内側からの外板外面に溶け込みが及ばない線状のレーザ重ね溶接によってそれらの問題を回避する技術を開示し、併せ、レーザ溶接時に外板などの歪み矯正とレーザ重ね合わせ溶接部の密着性向上を図る技術を提案している。

In Patent Document 2, in the case of spot welding, discoloration caused by high-temperature oxidation due to indentation due to electrode pressing or passing of a large current occurs, and those lasers are welded by linear laser lap welding that does not penetrate into the outer surface of the outer plate from the inside. A technique for avoiding the problem is disclosed, and a technique for correcting the distortion of the outer plate and the like and improving the adhesion of the laser overlap weld during laser welding is proposed.
Japanese Patent Laid-Open No. 8-25068 Japanese Patent Laid-Open No. 9-30414

ところで、特許文献1に記載のレーザ溶接では、ステンレス鋼板の外板の板厚が2mmを切ると、例えば図9に示すような外板aと骨材などの内側配置材bとのレーザ溶接接合部cのラインに沿う部分において、この溶接ラインを境に両側近傍がその周辺の内側への面外変形を伴い内向きに屈曲する例えば角折れと称される図示するような変形が生じ始め、板厚が小さくなるほど変形量が増す。これは、内側からのレーザ溶接による外板途中までの溶け込み部が凝固する際の凝縮が原因しており、その屈曲が大きくなるほど、外面が鏡面であるほど、平滑な外板での屈曲部からの正反射によって目立つことを経験している。塗装もされず鏡面のままとされるステンレス鋼板の外板において特に著しい。   By the way, in the laser welding described in Patent Document 1, when the thickness of the outer plate of the stainless steel plate is less than 2 mm, for example, laser welding joining between the outer plate a and the inner arrangement material b such as an aggregate as shown in FIG. In the portion along the line of the part c, the deformation shown in the figure called a corner fold, for example, called a corner fold, in which the vicinity of both sides is bent inward with an out-of-plane deformation inside the periphery of the weld line, The amount of deformation increases as the plate thickness decreases. This is due to the condensation when the melted part of the outer plate is solidified by laser welding from the inside. The larger the bend, the more the outer surface is the mirror surface, Experienced to stand out by regular reflection. This is especially true for the outer plate of a stainless steel plate that is not painted and remains a mirror surface.

一方、従来から走行している実車で多く見られるベルトグラインディング仕上げやヘアライン仕上げをした外板において、それらの研磨目の向きに沿う線状に行ったレーザ溶接による屈曲部は目立ちにくく、直交する向きに行ったレーザ溶接による屈曲部が目立つことを本発明者は経験しているし、知られてもいる。これは、研磨目が持っている研磨目に直交する方向への乱反射による視覚的なぼかし効果ないしは埋没効果といえる。   On the other hand, in the outer plate with belt grinding finish and hairline finish that are often seen in actual vehicles that have been running in the past, the bent parts by laser welding performed linearly along the direction of the polished eyes are not noticeable and are orthogonal The present inventor has experienced and is known to have a conspicuous bent portion by laser welding performed in the direction. This can be said to be a visual blurring effect or burial effect by irregular reflection in a direction perpendicular to the polishing eye.

しかし、外板aとレーザ溶接される内側配置材bは、車両の上下方向および長手方向に向く縦横に配置されるので、縦向きの骨材bの長手方向にレーザ溶接すると目立ってしまうが、一方向にしか仕上げ加工できないベルトグラインディング仕上げやヘアライン仕上げの研磨目によっては、縦横のレーザ溶接ラインに沿って生じる縦横の屈曲部双方に対応できない。また、スポット溶接痕には有効ではなく、目立たなくするには溶接後の表面加工によるしかない。また、外板自体の表面加工によるのでは、除去できない汚れや凹み傷が付いても交換できない不便がある。   However, since the inner arrangement material b laser welded to the outer plate a is arranged vertically and horizontally in the vertical direction and longitudinal direction of the vehicle, it becomes noticeable when laser welding is performed in the longitudinal direction of the vertical aggregate b. Depending on the belt grinding and hairline finishes that can only be finished in one direction, both vertical and horizontal bends that occur along the vertical and horizontal laser welding lines cannot be accommodated. Further, it is not effective for spot welding marks, and the only way to make it inconspicuous is by surface processing after welding. Moreover, there is an inconvenience that the outer plate itself cannot be replaced even if it has dirt or dents that cannot be removed by surface processing of the outer plate itself.

また、車両の外板の外面にシートフィルムを貼って装飾し、除去できない汚れや凹み傷が付いた場合、シートフィルムを貼り替えて対応することが行われている。不透明なシートフィルムによれば擦り傷はもとより、凹み傷でも凹み部から浮くことで全く目立たなくなる。しかし、シートフィルムが無地などの一様な外観を呈しているため、レーザ溶接による外方に凸な屈曲部のライン上ではこれを却って目立たせてしまうので採用できない。   In addition, when a sheet film is pasted and decorated on the outer surface of the outer plate of the vehicle, and a stain or dent scratch that cannot be removed is attached, the sheet film is replaced to cope with it. According to the opaque sheet film, not only scratches but also dents are not noticeable by floating from the dents. However, since the sheet film has a uniform appearance such as a solid color, it cannot be used because it is conspicuous on the line of the outwardly bent portion by laser welding.

本発明者は、除去できない汚れや傷に対し貼り替え対応できるシートフィルムが、印刷できるのは勿論、金属シートはもとより、URL[http://coburn.jp/products/products010102.html](非特許文献1)でネット上に公開されているように蒸着金属面にエンボス加工やエッチング加工ができることに着目し、レーザ溶接によるライン状の屈曲部やスポット溶接の圧痕を見立たなくすることを提案する。   The present inventor can print a sheet film that can be applied to dirt and scratches that cannot be removed, as well as a metal sheet, as well as a URL [http: // coburn. jp / products / products010102. [Html] (Non-patent Document 1) Focusing on the possibility of embossing and etching on the vapor-deposited metal surface as disclosed on the net, and invisible line-shaped bent portions by laser welding and spot welding indentations Suggest to do.

そこで、本発明の目的は、除去できない汚れや傷には貼り替えにて対応できるシートフィルムを用い、視覚的なぼかし効果、埋没効果、のほか周りとの同化度を高める同化効果などによるカモフラージュ効果と、それらの組み合わせを含め、溶接後の後仕上げなしに、レーザ溶接による縦横に走る屈曲部やスポット溶接痕であっても、目立ちにくくできる鉄道車両構体を提供することにある。   Therefore, the object of the present invention is to use a sheet film that can be replaced by dirt and scratches that cannot be removed, and a camouflage effect by visual blurring effect, burial effect, as well as an assimilation effect that increases the degree of assimilation with the surroundings In addition, the present invention is to provide a railway vehicle structure including a combination thereof, which can be made inconspicuous even if it is a bent portion or a spot weld mark that runs vertically and horizontally by laser welding without post-finishing after welding.

上記のような目的を達成するために、本発明の鉄道車両構体は、外板に内側の配置材や重ね材との溶接接合部を持った鉄道車両構体において、少なくとも側構体の外板は、その外面に、印刷、エンボス加工、研磨加工、エッチング加工の少なくとも1つによる、車両の長手方向またはおよび上下方向に向いた線状の荒らし粗面の平面模様か凹凸模様パターン、車両の長手方向またはおよび上下方向の方向性を持った微細幅形状および密集配列の微細な連続、不連続な平面模様か凹凸模様のパターン、車両の長手方向またはおよび上下方向の方向性を持った微細幅形状および密集配列の連続、不連続な平面模様か、凹凸模様に車両の長手方向またはおよび上下方向に向いた線状または非線状の荒らし粗面パターンを持った微細な平面模様か凹凸模様のパターン、定形、非定形で、車両の長手方向またはおよび上下方向に向いた線状または非線状の荒らし粗面を持った平面模様か凹凸模様のパターン、の少なくとも1つが形成されたシートフィルムが貼着されていることを1つの特徴としている。   In order to achieve the above-described object, the railway vehicle structure of the present invention is a railway vehicle structure having a welded joint with an inner arrangement material or a laminated material on the outer plate, at least the outer plate of the side structure is On the outer surface, a plane pattern or uneven pattern pattern of a linear rough surface facing the longitudinal direction of the vehicle or the vertical direction by at least one of printing, embossing, polishing, etching, or the longitudinal direction of the vehicle or And fine width shape with up and down direction and fine continuous of dense arrangement, discontinuous plane pattern or uneven pattern, fine width shape and denseness with vehicle longitudinal direction and up and down direction Fine planar pattern or unevenness with continuous or discontinuous planar pattern or uneven pattern with linear or non-linear roughening rough surface pattern oriented in the longitudinal or vertical direction of the vehicle A sheet in which at least one of a flat pattern or a concavo-convex pattern having a linear or non-linear roughening surface oriented in the longitudinal direction or the vertical direction of the vehicle is formed in a uniform pattern, a regular shape, an atypical shape One feature is that the film is attached.

このような構成では、外板の外面に貼り合わせたシートフィルムに形成してある平面模様や凹凸模様のパターンが、印刷、エンボス加工、研磨加工、エッチングの少なくとも1つによるものであるため、どのような平面模様や凹凸模様パターンでも形成して外板を装飾できるし、区分ごとに異なったパターンを形成し、または貼り分けて装飾することができ、レーザ溶接の向きの違いやレーザ溶接域とスポット溶接域の混在に対応して、それらによる屈曲やスポット痕などの溶接痕を、視覚的なぼかし効果、埋没効果、のほか周りとの同化度を高める同化効果やカムフラージュ効果と、それらの組み合わせが得られるし、少なくとも不透明部や線状、非線状の荒らしパターンによる乱反射部ではスポット溶接の圧痕や熱変色に対する覆い隠しができる。また、除去できない汚れや傷に対してはシートフィルムの貼り替えにて対応できる。ここで、シートフィルムの貼り合わせは、レーザ溶接やスポット溶接域、あるいはそれらの目立たなくしたい必要範囲に限って行えばよいが、車両の装飾上、必要範囲を超えた範囲、あるいは外板の全面に及ぶこともできる。   In such a configuration, the plane pattern or the uneven pattern formed on the sheet film bonded to the outer surface of the outer plate is due to at least one of printing, embossing, polishing, and etching. It is possible to decorate the outer plate by forming even a flat pattern or concavo-convex pattern like this, and it is possible to form different patterns for each section, or decorate them separately. Corresponding to the mixture of spot welding areas, welding blurs such as bending and spot marks, visual blurring effect, burying effect, as well as assimilation effect and camouflage effect that increase the degree of assimilation with the surroundings, and combinations thereof At least in opaque parts and irregular reflection parts due to linear or non-linear roughening patterns It can be. Moreover, it is possible to deal with dirt and scratches that cannot be removed by re-seat the sheet film. Here, the lamination of the sheet film may be performed only in the laser welding or spot welding area, or in the necessary range that is not desired to be conspicuous, but in the decoration of the vehicle, the range beyond the necessary range or the entire surface of the outer plate. Can extend to

特に、車両の長手方向またはおよび上下方向に向いた線状の荒らし粗面の平面模様のパターンであると、線状の向きに沿った横向きまたは縦向きのレーザ溶接による屈曲部を同化ないしはカモフラージュさせられるし、凹凸模様のパターンであると、同化効果に加え、さらに、入射光を線状の荒らし粗面パターンの向きに直交する方向にランダムに散乱させるが、この散乱方向は、車両の長手方向の線状の荒し粗面パターンでは、車両の長手方向に多用されるレーザ溶接による屈曲部に対して屈曲方向となって、屈曲面からの正反射なく背景部とほぼ同等の外観を呈する視覚的なぼかし効果ないしは埋没効果が得られる。また、車両の上下方向の線状の荒し粗面パターンでは、これに直交する方向にランダムに散乱させる散乱方向が線状の向きに沿った縦向きの柱材などとのレーザ溶接による屈曲部に対して屈曲方向となって、屈曲面からの正反射なく背景部とほぼ同等の外観を呈する視覚的なぼかし効果ないしは埋没効果も得られる。これら両方向の線状の荒し粗面の平面模様や凹凸模様のパターンを異なった溶接域ごとに個別に施し、あるいは貼り分けて対応することができ、その違いを車両全体での模様付けとすることもできるが、車両の長手方向および上下方向に向いた線状の荒らし粗面の平面模様や凹凸模様のパターンを合成したパターンとすることもでき、これにより、車両の長手方向に多用されるレーザ溶接による屈曲部と、柱材などに沿った上下方向のレーザ溶接による屈曲部との双方に対し、平面模様では視覚的な同化ないしはカモフラージュの効果、凹凸模様では視覚的なぼかし効果、埋没効果が得られる。   In particular, in the case of a line pattern of rough surface roughened in the longitudinal direction and the vertical direction of the vehicle, the bent portion by horizontal or vertical laser welding along the linear direction is assimilated or camouflaged. In addition to the assimilation effect, if the pattern is a concavo-convex pattern, the incident light is randomly scattered in a direction perpendicular to the direction of the linear roughening rough surface pattern. This scattering direction is the longitudinal direction of the vehicle. The linear rough surface pattern is a visual direction that is almost the same as the background without regular reflection from the bent surface, with the bent direction by the laser welding frequently used in the longitudinal direction of the vehicle. A smooth blur effect or buried effect. In addition, in the case of a linear rough surface pattern in the vertical direction of the vehicle, the scattering direction that randomly scatters in the direction orthogonal to the vertical direction is applied to the bent part by laser welding with a vertical column material along the linear direction. On the other hand, a visual blurring effect or an embedding effect is obtained which is in the bending direction and exhibits an appearance almost equal to the background without regular reflection from the bent surface. These two types of linear rough rough surface plane pattern and uneven pattern can be individually applied to different welding areas, or can be applied separately, the difference being the patterning on the entire vehicle However, it is also possible to make a pattern that is a combination of a linear roughened rough surface pattern or an uneven pattern oriented in the longitudinal direction and the vertical direction of the vehicle, and thus a laser that is frequently used in the longitudinal direction of the vehicle. For both the bent part by welding and the bent part by laser welding in the vertical direction along the pillar material, etc., there is a visual assimilation or camouflage effect in the planar pattern, and a visual blurring effect and a buried effect in the uneven pattern. can get.

また、車両の長手方向またはおよび上下方向の方向性を持った微細幅形状および密集配列の微細な連続、不連続の平面模様や凹凸模様のパターンであると、その微細度、密集度に応じた方向性のある外観は、それに一致する方向のレーザ溶接による屈曲部を周りの背景への視覚的な同化ないしはカモフラージュの効果および、凹凸模様であれば特に、凹凸面の傾斜や曲がりなどの形状も含めた入射光をレーザ溶接による屈曲部の屈曲方向に分散反射させてのぼかし効果、埋没効果も幾分得られる。レーザ溶接の方向の違いに対する対応は線状の荒し粗面パターンの場合と同様にできる。   Also, if the vehicle has a fine width shape with a longitudinal or vertical direction of the vehicle and a fine continuous, discontinuous plane pattern or uneven pattern with a dense arrangement, it corresponds to the fineness and denseness. The directional appearance also has the effect of visual assimilation or camouflaging the bent part by laser welding in the direction matching it to the surrounding background, and the shape of the uneven surface, such as the inclination and curvature of the uneven surface. A blurring effect and a burying effect can be obtained to some extent by dispersing and reflecting the included incident light in the bending direction of the bent portion by laser welding. Corresponding to the difference in the direction of laser welding can be performed in the same manner as in the case of a linear rough surface pattern.

また、車両の長手方向またはおよび上下方向の方向性を持った微細幅形状および密集配列の連続、不連続な平面模様か、凹凸模様に車両の長手方向またはおよび上下方向に向いた線状または非線状の荒らし粗面パターンを持った微細な連続、不連続の平面模様か凹凸模様のパターンであると、上記、車両の長手方向またはおよび上下方向の方向性を持った微細幅形状および密集配列の微細な平面模様や凹凸模様のパターンと同様な作用に加え、線状または非線状の荒らし粗面パターンでの平面模様による視覚的な同化やカムフラージュの効果、凹凸模様による入射光の方向性があるか方向性のない散乱作用が複合するので、レーザ溶接による屈曲部を周りの背景への視覚的なぼかし効果や埋没効果をさらに高められる。   In addition, a continuous or discontinuous plane pattern with a fine width shape and dense arrangement with the longitudinal direction of the vehicle or the vertical direction, or a concavo-convex pattern, a linear or non-directional pattern oriented in the longitudinal direction or the vertical direction of the vehicle. If the pattern is a fine continuous, discontinuous plane pattern or uneven pattern with a linear roughening rough surface pattern, the above-mentioned fine width shape and dense arrangement with the vehicle's longitudinal or vertical directionality In addition to the same effect as fine flat patterns and uneven patterns, visual assimilation and camouflage effects of linear or non-linear roughened rough surface patterns, directionality of incident light due to uneven patterns Since there is a composite of scattering action with or without directionality, it is possible to further enhance the visual blurring effect and burying effect on the background around the bent portion by laser welding.

また、定形、非定形で、車両の長手方向またはおよび上下方向に向いた線状または非線状の荒らし粗面を持った荒らし平面模様か凹凸模様のパターンであると、定形、非定形な模様パターンに線状、非線状な荒らし模様が複合した平面または凹凸の模様付けができるし、平面模様では線状の向きに沿うレーザ溶接の屈曲部に対する同化ないしはカモフラージュの効果、凹凸模様では特に、線状の荒らし面によるそれに直交する方向への入射光の微細散乱作用にて直線のレーザ溶接に沿った屈曲部のぼかし効果ないしは埋没効果が得られ、非線状荒らし面によっては入射光の方向性のない微細散乱によってレーザ溶接の向きに関係なくそれによる屈曲部のぼかし効果ないしは埋没効果が幾分得られる。   Also, if the pattern is rough or flat, with a rough or rough surface that is linear or non-linear, oriented in the longitudinal or vertical direction of the vehicle, it may be a regular or irregular pattern. The pattern can be flat or uneven with a combination of linear and non-linear roughening patterns on the pattern, the assimilation or camouflage effect on the bent part of laser welding along the linear direction in the flat pattern, especially in the uneven pattern, The effect of blurring or burying of the bent part along the straight line laser welding is obtained by the fine scattering action of the incident light in the direction perpendicular to the linear vanishing surface. Depending on the non-linear vanishing surface, the direction of the incident light is obtained. Due to the infinitesimal scattering, the effect of blurring or burying the bent portion is obtained somewhat regardless of the direction of laser welding.

本発明の鉄道車両構体は、また、上記の構成に加え、さらに外板に内側の配置材や重ね材との溶接接合部を持った鉄道車両構体において、側構体の外板は、鉄道車両の長手方向に向いてレーザ溶接接合する内側配置材の配置域を少なくともカバーした範囲で、1500〜10000mmの曲率半径を持って上下方向に湾曲していることを別の特徴としている。   In addition to the above-described structure, the railcar structure of the present invention further includes a railcar structure having a welded joint with an inner arrangement material or a laminated material on the outer plate. Another feature is that it is curved in the vertical direction with a radius of curvature of 1500 to 10000 mm within a range that covers at least the arrangement area of the inner arrangement material to be laser welded in the longitudinal direction.

このような構成では、上記の鉄道車両構体に加え、さらに、外板が内側配置材と鉄道車両の長手方向に向いてレーザ溶接してできる屈曲部の突出向きと、外板が1500〜10000mmの曲率半径を持った湾曲の突出向きが一致することで、入射光の拡散反射特性の点で共通し、屈曲部外面の外板外面に対する屈曲率および突出率を、平板に対するよりは低減し、かつ、外板の湾曲形状はレーザ溶接部を境にその両側がその周辺部の内側への面外変形を伴って内側に屈曲する変形力を、外側に凸の湾曲方向から内側に凸への反転に対する突っ張り抵抗にて抑えることによっても、レーザ溶接による屈曲部外面の外板外面に対する屈曲率および突出率を低減するので、湾曲した外板の外面とレーザ溶接による屈曲部外面との方向が一致している入射光の拡散特性の差を抑えて、鉄道車両の長手方向にレーザ溶接が行なわれる内側配置材の配置域においてレーザ溶接による屈曲部の背景に対するぼかし効果ないしは埋没効果が得られる。   In such a configuration, in addition to the above-described railway vehicle structure, the outer plate has a protruding direction of a bent portion formed by laser welding in the longitudinal direction of the inner arrangement member and the rail vehicle, and the outer plate has a thickness of 1500 to 10,000 mm. By matching the protruding direction of the curve having a radius of curvature, it is common in terms of the diffuse reflection characteristics of the incident light, and the bending rate and the protruding rate of the outer surface of the bent portion with respect to the outer surface of the outer plate are reduced compared to the flat plate, and The curved shape of the outer plate is reversed from the bending direction of the convex on the outside to the convex on the inner side, with the deformation force that bends inward with the out-of-plane deformation inward of the peripheral part at the boundary of the laser weld The bending resistance and the protrusion ratio of the outer surface of the bent portion by laser welding to the outer surface of the outer plate are also reduced by suppressing the tension resistance against the outer surface of the bent portion, so that the direction of the outer surface of the curved outer plate matches the outer surface of the bent portion by laser welding. Have To suppress the difference in the diffusion properties of the incident light, blurring effect or buried effects on the background of the bent portion by laser welding can be obtained in the arrangement region of the inner arrangement material laser welding in the longitudinal direction of the railway vehicle is performed.

粗面荒らし度は、砥粒の粒度で見て、60〜220番に相当するものとすることができる。   The rough surface roughening degree can correspond to Nos. 60 to 220 in terms of the grain size of the abrasive grains.

このような構成では、外板の外観を損なわない程度の平面的なあるいは凹凸のある荒らしパターンによって、溶接部を十分に目立たないか、目立ち難くすることができる。   In such a configuration, the welded portion is not sufficiently conspicuous or difficult to be conspicuous by a planar or uneven roughening pattern that does not impair the appearance of the outer plate.

シートフィルムは、金属シートの表面または金属の蒸着面にエンボス加工、研磨加工、またはエッチング加工された凹凸模様パターンを有したものとすることができる。   The sheet film may have a concavo-convex pattern that is embossed, polished, or etched on the surface of the metal sheet or the metal deposition surface.

このような構成では、シートフィルムの面に大きさ、形状、光学効果の違う各種の凹凸模様パターンを自由に選択し、また、同時、異時に複合して形成できる。   In such a configuration, various concavo-convex patterns having different sizes, shapes, and optical effects can be freely selected on the surface of the sheet film, and at the same time, they can be formed in combination at different times.

本発明の鉄道車両構体の1つの特徴によれば、外板の外面に貼り合わせたシートフィルムの平面模様や凹凸模様のパターンが、印刷、エンボス加工、研磨加工、エッチングの少なくとも1つによるもので、各種平面模様や凹凸模様パターンを形成して装飾し、区分ごとに異なったパターンの形成や貼り分けでの装飾もでき、これにより、レーザ溶接の向きの違いやレーザ溶接域とスポット溶接域の混在に対応して、それらによる屈曲やスポット痕などの溶接痕を、視覚的なぼかし効果、埋没効果、のほか周りとの同化やカムフラージュの効果と、それらの組み合わせが得られるし、少なくとも不透明部や線状、非線状の荒らしパターンによる乱反射部ではスポット溶接の圧痕や熱変色を覆い隠せる。また、除去できない汚れや傷に対してはシートフィルムの貼り替えにて対応できる。   According to one characteristic of the railway vehicle structure of the present invention, the planar pattern or the uneven pattern of the sheet film bonded to the outer surface of the outer plate is at least one of printing, embossing, polishing, and etching. It is possible to decorate by forming various plane patterns and concavo-convex patterns, and decorating by forming different patterns for each section or attaching them separately. Corresponding to mixing, welding marks such as bending and spot marks can be combined with visual blurring effect, burial effect, assimilation with surroundings and camouflage effects, and at least opaque parts In addition, the irregular reflection part by linear and non-linear roughening patterns can cover the spot welding indentation and thermal discoloration. Moreover, it is possible to deal with dirt and scratches that cannot be removed by re-seat the sheet film.

特に、車両の長手方向またはおよび上下方向に向いた線状の荒らし粗面の平面模様のパターンでは線状の向きに沿った横向きまたは縦向きのレーザ溶接による屈曲部を同化やカモフラージュ効果にて目立ち難くできるし、凹凸模様のパターンでは、特に、入射光の線状に直交する向きへの散乱作用による、線状に沿う縦向きまたはおよび横向きのレーザ溶接による屈曲部を視覚的なぼかし効果ないしは埋没効果にて目立たないか目立ち難くできる。これら両方向の線状の荒し粗面の平面模様や凹凸模様のパターンを併用するのに、異なった向きの溶接域ごとに個別に施し、あるいは貼り分けて対応でき、その違いを車両全体での模様付けとすることもできる。しかし、両方向の線状の荒らし粗面の平面模様や凹凸模様のパターンを重畳合成したパターンとして模様、意匠を統一することもできる。   In particular, in the pattern pattern of a rough lined rough surface facing the longitudinal direction or the vertical direction of the vehicle, the bent portion by horizontal or vertical laser welding along the linear direction is conspicuous due to assimilation or camouflage effect. It can be difficult, and in the case of uneven patterns, it is possible to visually blur or bury the bent portions by laser welding in the vertical and horizontal directions along the line, especially due to the scattering of incident light in the direction perpendicular to the line. The effect can be inconspicuous or inconspicuous. In order to use both the rough and rough surface patterns in both directions, and the uneven pattern, it can be applied to each welding area with different orientations or attached separately. It can also be attached. However, it is possible to unify the pattern and design as a pattern obtained by superimposing and synthesizing a planar pattern or a concavo-convex pattern of linear rough surfaces in both directions.

車両の長手方向またはおよび上下方向の方向性を持った微細幅形状および密集配列の微細な連続、不連続の平面模様や凹凸模様のパターンでは、その微細度、密集度に応じた方向性のある外観は、それに一致する方向のレーザ溶接による屈曲部を背景への視覚的な同化ないしはカモフラージュの効果および、凹凸模様であれば特に、凹凸面の傾斜や曲がりなどの形状も含めた入射光をレーザ溶接による屈曲部の屈曲方向に分散反射させてのぼかし効果、埋没効果も幾分得られ、方向が一致するレーザ溶接による屈曲部を目立ち難くできる。レーザ溶接の方向の違いに対する対応は線状の荒し粗面パターンの場合と同様にできる。   A fine width shape with a longitudinal or vertical direction of the vehicle and a dense continuous arrangement, a discontinuous plane pattern, or a pattern with a concavo-convex pattern has directionality according to its fineness and density. Appearance is laser assimilation or camouflage effect on the background of the bent portion by laser welding in the direction matching it, and incident light including shapes such as uneven and inclined surfaces, especially for uneven patterns A blurring effect and a burying effect obtained by dispersing and reflecting in the bending direction of the bent portion by welding are also somewhat obtained, and the bent portion by laser welding having the same direction can be made inconspicuous. Corresponding to the difference in the direction of laser welding can be performed in the same manner as in the case of a linear rough surface pattern.

車両の長手方向またはおよび上下方向の方向性を持った微細幅形状および密集配列の連続、不連続な平面模様か、凹凸模様に、車両の長手方向またはおよび上下方向に向いた線状または非線状の荒らし粗面パターンを持った微細な連続、不連続の平面模様か凹凸模様のパターンでは、上記方向性を持った微細幅形状および密集配列の微細な平面模様や凹凸模様のパターンと同様な作用に加え、線状または非線状の荒らし粗面パターンでの平面模様による視覚的な同化やカムフラージュの効果、凹凸模様による入射光の方向性があるか方向性のない散乱作用が複合するので、レーザ溶接による屈曲部を周りの背景への視覚的なぼかし効果や埋没効果をさらに高められる。   A continuous or discontinuous plane pattern or concavo-convex pattern with fine width shape and dense arrangement with longitudinal direction and vertical direction of the vehicle, linear or non-linear direction in the longitudinal direction or vertical direction of the vehicle A fine continuous or discontinuous planar pattern or uneven pattern with a rough surface rough pattern is the same as a fine planar pattern or uneven pattern with a fine width shape and dense arrangement with the above directionality. In addition to the action, the visual assimilation and camouflage effect due to the flat pattern in the linear or non-linear roughening rough surface pattern, and the scattering effect with or without directivity of the incident light due to the uneven pattern are combined. In addition, it is possible to further enhance the effect of visually blurring or burying the bent portion by laser welding on the surrounding background.

定形、非定形で、車両の長手方向またはおよび上下方向に向いた線状または非線状の荒らし粗面を持った荒らし平面模様か凹凸模様のパターンでは、定形、非定形な模様パターンに線状、非線状な荒らし模様が複合した平面または凹凸の模様付けができ、平面模様では線状の向きに沿うレーザ溶接の屈曲部に対する同化ないしはカモフラージュの効果、凹凸模様では特に、線状の荒らし面によるそれに直交する方向への入射光の微細散乱作用にて直線のレーザ溶接に沿った屈曲部のぼかし効果ないしは埋没効果が得られ、非線状荒らし面によっては入射光の方向性のない微細散乱によってレーザ溶接の向きに関係なくそれによる屈曲部のぼかし効果ないしは埋没効果が幾分得られる。   Regular or non-standard, rough or flat patterns with linear or non-linear rough surfaces facing the longitudinal or vertical direction of the vehicle. It is possible to create a flat or uneven pattern with a combination of non-linear roughening patterns. In the flat pattern, the effect of assimilation or camouflage on the bent part of the laser welding along the linear direction. By the fine scattering action of incident light in the direction perpendicular to it, the blurring effect or burial effect of the bent part along the straight line laser welding is obtained, and depending on the non-linear roughening surface, the fine scattering without the directivity of the incident light Therefore, the effect of blurring or burying the bent portion can be obtained somewhat regardless of the direction of laser welding.

本発明の鉄道車両構体の別の特徴では、1つの特徴に加え、さらに、外板のレーザ溶接による屈曲部の突出向きと外板の湾曲の突出向きが同じで、それらの屈曲方向、湾曲方向への入射光の拡散反射特性が共通すること、屈曲部外面の外板外面に対する屈曲率および突出率が、平板の場合より低減すること、外板の湾曲形状がレーザ溶接部を境にした両側におけるさらにその周辺部の内側への面外変形を伴った屈曲を抑えること、の複合によって、湾曲した外板の外面とレーザ溶接による屈曲部外面との方向が一致している入射光の拡散特性の差を抑えられ、鉄道車両の長手方向にレーザ溶接が行なわれる内側配置材の配置域においてレーザ溶接による屈曲部を目立ち難くすることができる。   In another feature of the railway vehicle structure of the present invention, in addition to one feature, the protruding direction of the bent portion by laser welding of the outer plate and the protruding direction of the curved outer plate are the same. The diffuse reflection characteristics of the incident light to the surface are the same, the bending rate and protrusion rate of the outer surface of the bent portion with respect to the outer surface of the outer plate are reduced compared to the case of a flat plate, and the curved shape of the outer plate is on both sides of the laser weld The diffusion characteristics of incident light in which the direction of the outer surface of the curved outer plate and the outer surface of the bent portion by laser welding are matched by the combination of further suppressing the bending with the out-of-plane deformation to the inside of the peripheral portion Thus, the bent portion by laser welding can be made inconspicuous in the arrangement region of the inner arrangement material where laser welding is performed in the longitudinal direction of the railway vehicle.

前記粗面荒らし度が、砥粒の粒度で見て、60〜220番に相当することにより、外板の外観を損なわない程度の平面的あるいは凹凸のある荒らし模様パターンによって、溶接部を十分に目立たないか、目立ち難くすることができる。   When the rough surface roughening degree corresponds to No. 60 to 220 in terms of the grain size of the abrasive grains, the welded portion can be sufficiently formed by a rough or uneven roughening pattern that does not impair the appearance of the outer plate. Can be inconspicuous or inconspicuous.

金属シートの表面またはシートフィルムの金属蒸着面にエンボス加工、研磨加工、またはエッチング加工した凹凸模様パターンによれば、シートフィルムの面に大きさ、形状、光学効果の違う各種の凹凸模様パターンを自由に選択し、また、同時、異時に複合して形成でき、装飾および溶接痕に対する視覚的効果を高めやすい。   According to the concavo-convex pattern embossed, polished, or etched on the surface of the metal sheet or the metal deposition surface of the sheet film, various concavo-convex patterns with different sizes, shapes, and optical effects can be freely applied to the surface of the sheet film. In addition, it can be formed at the same time and at the same time, and it is easy to enhance the visual effect on decoration and welding marks.

以下、本発明に係る実施の形態の鉄道車両構体について図1〜図8を参照しながら説明し、本発明の理解に供する。なお、以下の説明および図示は、本発明の具体例であって、特許請求の範囲の記載内容を限定するものではない。   Hereinafter, a railway vehicle structure according to an embodiment of the present invention will be described with reference to FIGS. 1 to 8 for understanding of the present invention. The following description and illustration are specific examples of the present invention, and do not limit the description of the scope of the claims.

本実施の形態は、主としてステンレス鋼板よりなる外板2の外面に、図1、図2、図4に示す鉄道車両1の長手方向に配した骨材としての内側配置材3、図2に示すような縦向きの柱材としての内側配置材4や補強材としての内側配置材5、あるいは各種の重ね材との溶接接合部6を持った鉄道車両構体1を対象としている。しかし、これに、限られることはなく、例えば溶接接合部6はレーザ溶接に限らずスポット溶接にも対応できる。   In the present embodiment, an inner arrangement material 3 as an aggregate disposed in the longitudinal direction of the railway vehicle 1 shown in FIGS. 1, 2, and 4 is shown in FIG. 2, on the outer surface of an outer plate 2 mainly made of a stainless steel plate. The present invention is intended for the rail vehicle structure 1 having the inner arrangement member 4 as a vertically oriented pillar member, the inner arrangement member 5 as a reinforcing member, or a welded joint 6 with various kinds of overlapping members. However, the present invention is not limited to this. For example, the weld joint 6 can be used not only for laser welding but also for spot welding.

本実施の形態の鉄道車両構体1は、特に、図1、図2、図4に示す少なくとも側構体11の外板2が、外面に、印刷、エンボス加工、研磨加工、エッチング加工の少なくとも1つによる、図2、図3に示すような車両の長手方向Aまたはおよび上下方向Bに向いた線状の荒らし粗面の平面模様か凹凸模様パターンP1、P2、P3、図1に破線で平面模様か凹凸模様の凹部または凸部を模して示すような車両の長手方向Aまたはおよび上下方向Bの方向性を持った微細幅形状および密集配列の微細な平面模様か凹凸模様パターンP4、図5、図6に示すような車両の長手方向Aまたはおよび上下方向Bの方向性を持った微細幅形状および密集配列の平面模様か凹部に車両の長手方向Aまたはおよび上下方向Bに向いた線状または非線状の荒らし粗面パターンを持った平面模様か凹凸模様パターンP5、P6、P7、P8、P9、図7に示すような定形(図示せず)、非定形な形状で密集した平面模様か凹凸模様パターンP10、さらにそれに車両の長手方向Aまたはおよび上下方向Bに向いた線状または非線状の荒らし粗面を持った平面模様か凹凸模様パターンP11、P12、P13、P14、の少なくとも1つが形成されたシートフィルム21が貼着されたものとしている。   In the railway vehicle structure 1 of the present embodiment, in particular, at least one of the outer plate 2 of the side structure 11 shown in FIGS. 1, 2, and 4 is printed, embossed, polished, or etched on the outer surface. 2 and FIG. 3, a plane pattern of rough rough surfaces or uneven patterns P1, P2, and P3 facing in the longitudinal direction A and the vertical direction B of the vehicle as shown in FIG. 2 and FIG. FIG. 5 shows a fine plane pattern or a concave / convex pattern P4 having a fine width shape and a dense arrangement with a directionality in the longitudinal direction A or the vertical direction B of the vehicle, which is shown by imitating a concave or convex portion of the concave / convex pattern. 6, a fine width shape having a directivity in the longitudinal direction A or the vertical direction B of the vehicle and a plane pattern or a concave portion in a dense arrangement, and a linear shape facing the longitudinal direction A or the vertical direction B of the vehicle. Or non-linear rough Planar pattern or rough pattern P10, P6, P7, P8, P9 having a rough surface pattern, a regular pattern (not shown) as shown in FIG. Further, a sheet on which at least one of a planar pattern or a concavo-convex pattern P11, P12, P13, P14 having a linear or non-linear roughening surface facing the longitudinal direction A or the vertical direction B of the vehicle is formed. It is assumed that the film 21 is attached.

ここで、シートフィルムは巻き取って取り扱える取り扱い性や曲面への貼り合わせなどの貼着の作業性、馴染み性などのために柔軟性を有しているのがよく、塩ビ、PET、アクリルなどの樹脂材料が代表的に挙げられる。中でも、PETはリサイクル性により、アクリルは焼却時に有害ガスが殆ど発生しないことにより、それぞれ環境にやさしいものとなる。また、樹脂製のシートフィルム21はどのように形成されたものでもよいが、0.015mm〜30mm程度の厚みの極薄フィルムから極厚シートまでを押出成形する各種実機がある。押出成形直後のシートフィルム21にはホットローラなどによって、荒らし、研磨、レーザ、エッチングなどにて表面に形成できるあらゆる種類の凹凸模様を転写した凹凸模様パターンをエンボス加工することができる。金属シートでは箔に近づくほど柔軟性はあるが腰が弱く取り扱い難い場合は適度に厚みを増したシートにすればよい。   Here, the sheet film should have flexibility for easy handling, handling work for sticking to curved surfaces, familiarity, etc., such as PVC, PET, acrylic, etc. A resin material is typically mentioned. Among them, PET is environmentally friendly due to recyclability, and acrylic has almost no harmful gas generated during incineration. The resin sheet film 21 may be formed in any manner, but there are various actual machines for extruding from a very thin film having a thickness of about 0.015 mm to 30 mm to a very thick sheet. The sheet film 21 immediately after the extrusion can be embossed with a hot roller or the like to transfer a concavo-convex pattern on which all kinds of concavo-convex patterns that can be formed on the surface by roughening, polishing, laser, etching or the like are transferred. A metal sheet is more flexible as it gets closer to the foil, but if it is difficult to handle because it is weak, it may be made a sheet with a moderately increased thickness.

また、シートフィルム21は、金属シートの表面または樹脂シートフィルムの金属蒸着面にエンボス加工、研磨加工、またはエッチング加工された凹凸模様パターンを有したものとして、シートフィルム21の面に大きさ、形状、光学効果の違う各種の凹凸模様パターンを自由に選択し、また、同時、異時に複合して形成でき、装飾および溶接痕に対する視覚的効果を高めやすい。   In addition, the sheet film 21 has a concavo-convex pattern that is embossed, polished, or etched on the surface of the metal sheet or the metal vapor-deposited surface of the resin sheet film. Various uneven patterns with different optical effects can be freely selected, and can be formed simultaneously and at the same time, and it is easy to enhance the visual effect on decorations and welding marks.

以上のように、外板2の外面に貼り合わせたシートフィルム21に形成してある平面模様や凹凸模様のパターンP1〜P14が、印刷、エンボス加工、研磨加工、エッチングの少なくとも1つによるものであるため、どのような平面模様や凹凸模様パターンでも形成して外板2を装飾できるし、区分ごとに異なったパターンを形成し、または図1に示すように貼り分けて装飾することができ、レーザ溶接の向きの違いやレーザ溶接域とスポット溶接域の混在に対応して、それらによる屈曲やスポット痕などの溶接痕を、視覚的なぼかし効果、埋没効果、のほか周りとの同化度を高める同化効果やカムフラージュ効果と、それらの組み合わせが得られるし、少なくとも不透明部や線状、非線状の荒らしパターンP1、P2、P3による乱反射部ではスポット溶接の圧痕や熱変色に対する覆い隠しができる。また、除去できない汚れや傷に対してはシートフィルム21の貼り替えにて対応できる。なお、シートフィルム21の貼り合わせは、レーザ溶接やスポット溶接域、あるいはそれらの目立たなくしたい必要範囲に限って行えばよいが、車両の装飾上、前記必要範囲を超えた範囲、あるいは外板2の全面に及ぶこともできる。   As described above, the patterns P1 to P14 of the planar pattern and the concavo-convex pattern formed on the sheet film 21 bonded to the outer surface of the outer plate 2 are due to at least one of printing, embossing, polishing, and etching. Therefore, it is possible to decorate the outer plate 2 by forming any plane pattern or concavo-convex pattern, or to form a different pattern for each section, or to paste and decorate as shown in FIG. Corresponding to the difference of laser welding direction and the mixture of laser welding area and spot welding area, the welding marks such as bending and spot marks can be visually blurred effect, buried effect, as well as the assimilation degree with the surroundings The assimilation effect and camouflage effect to be enhanced and the combination thereof can be obtained, and at least the opaque portion and the irregular reflection portion by the linear and non-linear roughening patterns P1, P2, and P3 It can Burying against indentation and thermochromic spot welding. In addition, it is possible to deal with dirt and scratches that cannot be removed by replacing the sheet film 21. The sheet film 21 may be bonded only to a laser welding or spot welding region, or to a necessary range in which the sheet film 21 is not conspicuous. Can also cover the entire surface.

特に、車両の長手方向Aまたはおよび上下方向Bに向いた線状の荒らし粗面の平面模様のパターンP1〜P3では線状の向きに沿った横向きまたは縦向きのレーザ溶接による屈曲部を同化やカモフラージュ効果にて目立ち難くできるし、凹凸模様のパターンP1〜P3では、特に、入射光の線状に直交する向きへの散乱作用による、線状に沿う縦向きまたはおよび横向きのレーザ溶接による屈曲部を視覚的なぼかし効果ないしは埋没効果にて目立たないか目立ち難くできる。これら両方向の線状の荒し粗面の平面模様や凹凸模様のパターンP1、P2をP3のように併用するのに、図1に示すように異なった向きの溶接域ごとに個別に施し、あるいは貼り分けて対応でき、その違いを車両全体での模様付けとすることもできる。しかし、図2に示すように両方向の線状の荒らし粗面の平面模様や凹凸模様のパターンを重畳合成したパターンとして模様、意匠を統一することもできる。   In particular, in the patterns P1 to P3 of the linear roughening rough surface oriented in the longitudinal direction A or the vertical direction B of the vehicle, the bent portion by the horizontal or vertical laser welding along the linear direction is assimilated. The camouflage effect makes it inconspicuous, and in the concavo-convex patterns P1 to P3, in particular, a bent portion by longitudinal or lateral laser welding along the linear shape due to the scattering action of the incident light in the direction orthogonal to the linear shape. Can be made inconspicuous or inconspicuous by visual blurring effect or burial effect. In order to use these flat and rough patterns P1 and P2 of linear rough surfaces in both directions like P3, it is applied individually or welded to each welding area in different directions as shown in FIG. It can be handled separately, and the difference can be used as a pattern for the entire vehicle. However, as shown in FIG. 2, the pattern and design can be unified as a pattern obtained by superimposing and synthesizing a planar rough surface pattern or an uneven pattern in both directions.

また、図1に破線で平面模様か凹凸模様の凹部または凸部を模して示すような車両の長手方向Aまたはおよび上下方向Bの方向性を持った微細幅形状および密集配列の微細な連続、不連続の平面模様や凹凸模様のパターンP4であると、その微細度、密集度に応じた方向性のある外観は、それに一致する方向のレーザ溶接による屈曲部を周りの背景への視覚的な同化ないしはカモフラージュの効果および、凹凸模様パターンP4であれば特に、凹凸面の傾斜や曲がりなどの形状も含めた入射光をレーザ溶接による屈曲部の屈曲方向に分散反射させてのぼかし効果、埋没効果も幾分得られる。レーザ溶接の方向の違いに対する対応は線状の荒し粗面パターンP1〜P3の場合と同様にできる。ここで、平面模様か凹凸模様パターンP4は、連続したもの、不連続なものを含み、不連続な場合の方向性は、方向性を持たせる向きの平面模様パターンP4の不連続間隔か凹凸模様パターンP4の凹部または凸部の不連続間隔が、これに直交する方向の間隔よりも小さいこと、平面模様パターンP4の幅か凹凸模様パターンP4の凹部または凸部の方向性を持たせる向きの大きさが、これに直交する向きの幅よりも大きいこと、の少なくとも一方によって得られる。しかし、レーザ溶接による屈曲部に対する視覚的な同化ないしは埋没を効果的に図るには、方向性を強める方がよく連続性が好適で方向性を与える向きに直角な方向に線パターンが間隔を置くか、異なった種類の線パターンが並ぶか、線状凹部と線状凸部とが交互に並ぶパターンになる。また、線状凹部と線状凸部はレーザ溶接による屈曲部の幅と同等程度で同化が図れるが、屈曲部に複数の線状凹凸部が載る太さ程度未満の微細幅として入射光を幅方向に乱して視覚的なぼかし効果、埋没効果をも幾分得て、より目立たないか、目立ち難くすることができる。この場合も幅方向の傾斜や湾曲を併用することによって幅方向への入射光の散乱度をさらに高められる。   In addition, as shown by a broken line in FIG. 1 simulating a concave portion or a convex portion of a plane pattern or an uneven pattern, a fine width shape having a directivity in the longitudinal direction A or the vertical direction B of the vehicle and a fine continuation of a dense arrangement When the pattern P4 is a discontinuous plane pattern or concavo-convex pattern, the directional appearance according to the fineness and density is visually reflected on the surrounding background by the bent portion by laser welding in the direction matching it. Assimilation or camouflage effect and, in the case of the concavo-convex pattern P4, in particular, the blurring effect by diffusing and reflecting incident light including the shape of the concavo-convex surface such as the inclination and bending in the bending direction of the bent portion by laser welding, Some effect is also obtained. Corresponding to the difference in the direction of laser welding can be performed in the same manner as in the case of the linear rough surface patterns P1 to P3. Here, the flat pattern or the uneven pattern P4 includes a continuous pattern or a discontinuous pattern. The directionality in the case of the discontinuity is the discontinuous interval or the uneven pattern of the plane pattern pattern P4 having a direction. The discontinuous interval of the concave portion or convex portion of the pattern P4 is smaller than the interval in the direction orthogonal thereto, and the width of the plane pattern pattern P4 or the direction in which the directionality of the concave portion or convex portion of the concave and convex pattern P4 is given. Is greater than the width in the direction perpendicular thereto. However, in order to effectively achieve visual assimilation or embedding of the bent part by laser welding, it is better to increase the directionality, the continuity is preferable, and the line pattern is spaced in a direction perpendicular to the direction giving the directionality. Alternatively, different types of line patterns are arranged, or linear concave portions and linear convex portions are alternately arranged. In addition, the linear recesses and linear protrusions can be assimilated to the same extent as the width of the bent portion by laser welding, but the width of incident light is reduced to a fine width less than about the thickness where a plurality of linear uneven portions are placed on the bent portion. By disturbing the direction, you can get some visual blurring effect and burying effect, making it less noticeable or less noticeable. Also in this case, the scattering degree of incident light in the width direction can be further increased by using the inclination and curvature in the width direction together.

また、図示しないが、前記方向性を持った微細凹凸模様・パターンP4の凹部および凸部の少なくとも一方に、方向性が一致する線状または非線状の荒らし粗面パターンを持った荒らし微細凹凸模様・パターンにすると、微細凹凸模様・パターンP4と同様な作用、効果に、線状または非線状の荒らし粗面パターンによる入射光の方向性があるか方向性のない散乱作用が複合するので、レーザ溶接による屈曲部の周りの背景へのぼかし効果や埋没効果をさらに高められるので、屈曲部がさらに目立ち難くすることができる。   Further, although not shown in the drawing, rough fine irregularities having a linear or non-linear roughening rough surface pattern having the same directionality on at least one of the concave and convex portions of the fine concavo-convex pattern / pattern P4 having the directionality. When the pattern / pattern is used, the same action and effect as the fine concavo-convex pattern / pattern P4 are combined with the directional or non-directional scattering action of the incident light by the linear or non-linear roughening rough surface pattern. Since the blurring effect and the burying effect on the background around the bent portion by laser welding can be further enhanced, the bent portion can be made more inconspicuous.

また、図5、図6に示すような定形、図7に示すような非定形な平面模様か凹凸模様パターンP5、P10で透明部と不透明部とによって模様化して、透明部にスポット溶接の圧痕が透けても、背景への同化やカムフラージュの効果が得られ、目立たなくすることができる。形状の類似度によっては埋没効果も幾分得られる。しかし、本発明者の実験によれば、図5、図6、図7に示すサイズの平面模様か凹凸模様パターンP5、P10では模様付け効果は得られても、鏡面による正反射がレーザ溶接による屈曲部の形状を外観させてしまい凸部の丸みのある外面によっても目立ち難くすることができなかった。図7に示すような凹凸模様・パターンP10を図8に示すサイズまで小さくすると、鏡面の連続性がきめ細かく崩れてレーザ溶接による屈曲部の目立ち程度が半減し始め、さらにサイズを1/2程度に小さくすると模様付け効果に加え、レーザ溶接による屈曲部を目立ち難くする効果も得られる。   5 and FIG. 6, a non-standard planar pattern as shown in FIG. 7 or uneven pattern P5, P10, and patterned with a transparent part and an opaque part, and an indentation of spot welding on the transparent part Even if it is transparent, the effect of assimilation to the background and camouflage can be obtained, making it less noticeable. Depending on the degree of similarity in shape, a sunk effect can be obtained. However, according to the experiments of the present inventors, even if the patterning effect is obtained in the planar pattern or the uneven pattern P5, P10 of the size shown in FIGS. 5, 6, and 7, the regular reflection by the mirror surface is caused by laser welding. The shape of the bent portion was made to appear, and the outer surface with the rounded convex portion could not be made inconspicuous. When the concavo-convex pattern / pattern P10 as shown in FIG. 7 is reduced to the size shown in FIG. 8, the continuity of the mirror surface is finely broken, and the conspicuous degree of the bent portion by laser welding starts to be halved. If it is made small, in addition to the patterning effect, an effect of making the bent part by laser welding inconspicuous is also obtained.

しかし、このような定形、非定形な平面模様か凹凸模様パターンP5、P10を、図5、図6、図7に示すような車両1の長手方向Aまたはおよび上下方向Bに向いた線状または非線状の荒らし粗面を持った平面模様か、凹凸模様パターンP6〜P9、P11〜P14にすると、定形、非定形な模様パターンに線状、非線状な荒らし模様が複合した平面または凹凸の模様付けができ、平面模様パターンP6〜P9、P11〜P14では線状の向きに沿うレーザ溶接の屈曲部に対する同化ないしはカモフラージュの効果を得てその分目立ち難くすることができる。凹凸模様パターンP6〜P9、P11〜P14では特に、レーザ溶接による連続した屈曲部を凹凸模様によって視覚的に分断するのに併せ、線状の荒らし面によるそれに直交する方向への入射光の微細散乱作用にて直線のレーザ溶接に沿った屈曲部のぼかし効果ないしは埋没効果が得られ、非線状荒らし面によっては入射光の方向性のない微細散乱によってレーザ溶接の向きに関係なくそれによる屈曲部のぼかし効果ないしは埋没効果が幾分得られ、目立たなくすることができる。   However, such a regular, non-standard planar pattern or concavo-convex pattern P5, P10 is formed into a linear shape facing the longitudinal direction A or the vertical direction B of the vehicle 1 as shown in FIGS. If a flat pattern with a non-linear roughening surface, or an uneven pattern P6 to P9, P11 to P14, a flat or uneven surface where a linear or non-linear roughening pattern is combined with a regular or non-standard pattern pattern. In the plane pattern patterns P6 to P9 and P11 to P14, the effect of assimilation or camouflaging with respect to the bent portion of the laser welding along the linear direction can be obtained to make it less noticeable. In particular, in the uneven pattern P6 to P9 and P11 to P14, the continuous bending portion by laser welding is visually divided by the uneven pattern, and fine scattering of incident light in the direction perpendicular to the linear roughening surface is performed. The effect of blurring or burying of the bent part along the straight line of laser welding is obtained by the action, and depending on the non-linear roughening surface, the bent part caused by fine scattering without directivity of incident light regardless of the direction of laser welding. The effect of blurring or burying is somewhat obtained and can be made inconspicuous.

ところで、本発明者の実験によれば、粗面の荒らし度は、砥粒の粒度で見て、60〜220番であるのが好適であり、外板2の外観を損なわない程度の荒らしによって、溶接接合部6における溶接痕の背景に対するぼかし効果ないしは埋没効果、同化効果が十分に得られ、目立たなくすることができる。   By the way, according to the inventor's experiment, the roughening degree of the rough surface is preferably 60 to 220 in view of the grain size of the abrasive grains, and the roughening does not impair the appearance of the outer plate 2. The blurring effect, the burial effect, and the assimilation effect with respect to the background of the weld mark in the weld joint 6 can be sufficiently obtained and made inconspicuous.

最後に、鉄道車両構体1は図4に示すように、側構体11の外板2が、鉄道車両1の長手方向に向いてレーザ溶接接合する内側配置材3の配置域を少なくともカバーした範囲で、1500〜10000mmの曲率半径を持った上下方向に湾曲している。このようにすると、外板2が内側配置材3と鉄道車両1の長手方向に向いてレーザ溶接してできる屈曲部の突出向きと、外板2が1500〜10000mmの曲率半径を持った湾曲の突出向きが一致することで、入射光の拡散反射特性の点で共通し、屈曲部外面の外板2外面に対する屈曲率および突出率を、平板に対するよりは低減し、かつ、外板2の湾曲形状はレーザ溶接接合部6を境にその両側がその周辺部の内側への面外変形を伴って内側に屈曲する変形力を、外側に凸の湾曲方向から内側に凸への反転に対する突っ張り抵抗にて抑えることによっても、レーザ溶接による屈曲部外面の外板2外面に対する屈曲率および突出率を低減するので、湾曲した外板2の外面とレーザ溶接による屈曲部外面との方向が一致している入射光の拡散特性の差を抑えて、鉄道車両1の長手方向Aにレーザ溶接が行なわれる内側配置材の配置域においてレーザ溶接による屈曲部の背景に対するぼかし効果ないしは埋没効果が得られ、上記した各種のパターンP1〜P14なとの併用で、より目立ち難くすることができる。   Finally, as shown in FIG. 4, the railway vehicle assembly 1 has a range in which the outer plate 2 of the side construction 11 covers at least the arrangement area of the inner arrangement member 3 that is laser-welded in the longitudinal direction of the railway vehicle 1. Curved vertically with a radius of curvature of 1500-10000 mm. In this way, the outer plate 2 is bent in the protruding direction of the bent portion formed by laser welding in the longitudinal direction of the inner arrangement member 3 and the railcar 1, and the outer plate 2 is curved with a curvature radius of 1500 to 10,000 mm. By matching the protruding directions, it is common in terms of the diffuse reflection characteristics of incident light, the bending rate and the protruding rate of the outer surface of the bent portion with respect to the outer surface of the outer plate 2 are reduced as compared with the flat plate, and the curvature of the outer plate 2 is reduced. As for the shape, the laser welding joint 6 is used as a boundary, and both sides of the laser welding joint 6 are deformed to be bent inward with out-of-plane deformation to the inside of the peripheral part. Also, since the bending rate and the protrusion rate of the outer surface of the bent portion by laser welding with respect to the outer surface of the outer plate 2 are reduced, the directions of the outer surface of the curved outer plate 2 and the outer surface of the bent portion by laser welding coincide with each other. Diffuse incident light In the arrangement region of the inner arrangement material in which laser welding is performed in the longitudinal direction A of the railway vehicle 1 while suppressing the difference in properties, a blurring effect or a buried effect on the background of the bent portion by laser welding is obtained, and the various patterns P1 described above By using together with ~ P14, it can be made more inconspicuous.
