Description

本発明は、鉄道車両の側構体の構造に係り、詳しくは、外板外面の見栄えを良好に保ちながら側構体を確実に補強することができる鉄道車両に関する。   The present invention relates to a structure of a side structure of a railway vehicle, and more particularly, to a railway vehicle that can reliably reinforce a side structure while maintaining a good appearance of an outer surface of an outer plate.

近年のステンレス製鉄道車両における側構体として、ステンレス製の外板の内側に補強材を接合した構造のものが多く製造されている。前記補強材としては、外板内面に所定間隔で横骨と縦骨とを接合したもの（例えば、特許文献１参照。）や、外板内面全体にコルゲート板を接合したもの（例えば、特許文献２参照。）が知られている。
特開２００６−３４１３００号公報 特開平１１−２７８２５８号公報 As a side structure in a stainless steel railway vehicle in recent years, many structures having a structure in which a reinforcing material is joined to the inside of a stainless steel outer plate are manufactured. Examples of the reinforcing material include a material in which a lateral bone and a longitudinal bone are joined to the inner surface of the outer plate at predetermined intervals (for example, refer to Patent Document 1), and a material in which a corrugated plate is joined to the entire inner surface of the outer plate (for example, Patent Document). 2) is known.
JP 2006-341300 A JP 11-278258 A

従来のように、外板に横骨や縦骨、あるいはコルゲート板を直接溶接して接合すると、その溶接痕が外板に残り外板外面の外観を悪化させる。レーザー溶接で車体長手方向に連続的に発生した線状の溶接痕は、外板外面の車体長手方向に施されるヘアライン仕上げなどによって目立たなくすることができるが、車体上下方向に発生した線状の溶接痕やスポット溶接の点状の溶接痕は、鉄道車両を見るときの視線の動きとも相俟って非常に目立つものとなる。   When a lateral bone, a longitudinal bone, or a corrugated plate is directly welded and joined to the outer plate as in the prior art, the welding marks remain on the outer plate and deteriorate the appearance of the outer surface of the outer plate. The linear welding marks that are continuously generated in the longitudinal direction of the car body by laser welding can be made inconspicuous by the hairline finish applied in the longitudinal direction of the car body on the outer surface of the outer plate. These welding marks and spot-like welding marks of spot welding become very conspicuous in combination with the movement of the line of sight when viewing the railway vehicle.

このため、レーザー溶接によって補強材を外板に溶接する場合は、溶接痕を目立たなくするために横骨が主体となるため、車体上下方向の剪断力に対する剛性の確保が難しく、面外変形に対応するためには、外板や補強材の強度を増したり、補強材の数を多くする必要があった。しかし、外板や補強材の強度を増すために肉厚を厚くしたり、補強材の数を多くしたりすると重量が増加し、また、部材コストも増加するという問題がある。   For this reason, when welding the reinforcing material to the outer plate by laser welding, it is difficult to ensure rigidity against the shearing force in the vertical direction of the vehicle body because the horizontal bones are mainly used to make the welding marks inconspicuous. In order to cope with this, it was necessary to increase the strength of the outer plate and the reinforcing material or to increase the number of reinforcing materials. However, when the thickness is increased or the number of reinforcing materials is increased in order to increase the strength of the outer plate or the reinforcing material, there is a problem that the weight increases and the member cost also increases.

そこで本発明は、外板を効果的に補強することができるとともに、外板外面の見栄えも良好な側構体を備えた鉄道車両を提供することを目的としている。   SUMMARY OF THE INVENTION An object of the present invention is to provide a railway vehicle having a side structure that can effectively reinforce an outer plate and has a good appearance on the outer surface of the outer plate.

上記目的を達成するため、本発明の鉄道車両は、鉄道車両の側構体を構成する外板の内面に、車体長手方向に向けた複数の横骨を上下多段に接合するとともに、該複数の横骨の車体内側面に、凸状部と凹状部とが連続する方向を車体上下方向に向けたコルゲート板を接合したことを特徴としている。   In order to achieve the above object, a railway vehicle according to the present invention joins a plurality of lateral bones in the longitudinal direction of the vehicle body to the inner surface of the outer plate constituting the side structure of the railway vehicle in a vertical and multistage manner. A corrugated plate having a direction in which the convex portion and the concave portion are continuous in the vertical direction of the vehicle body is joined to the inner surface of the vehicle body of the bone.

さらに、本発明の鉄道車両は、前記外板と前記横骨とは、レーザー溶接にて接合されていること、また、前記コルゲート板は、鉄道車両構体の剛性確保を考慮し、側構体下部に接合される台枠の枕梁の位置に対して車体中央側の直近に位置した出入口引戸用戸袋部分に設けられることを特徴としている。   Furthermore, in the railway vehicle of the present invention, the outer plate and the lateral bone are joined by laser welding, and the corrugated plate is provided at the lower part of the side structure in consideration of securing rigidity of the railway vehicle structure. It is characterized in that it is provided in the door pocket portion for the entrance / exit sliding door located in the immediate vicinity of the center of the vehicle body with respect to the position of the pillow beam of the underframe to be joined.

本発明の鉄道車両によれば、複数の横骨の内側面に接合したコルゲート板によって外板（側構体）を効果的に補強することができ、コルゲート板の凸状部と凹状部とが連続する方向を車体上下方向に向けることにより、車体上下方向の剪断力に対する剛性を高めることができ、面外変形を防止して車体全体の剛性を向上させることができる。さらに、外板や横骨の肉厚を薄くできるので、車体の軽量化やコストダウンを図ることができる。また、コルゲート板を横骨の車体内側面に接合することにより、外板には関係なくコルゲート板を接合することができるので、外板の外観に悪影響を与えることもない。また、外板と横骨とをレーザー溶接で接合することにより、外板の溶接痕は車体長手方向になるので、今まで同様のヘアライン仕上げなどを施すことによって良好な外観に仕上げることができる。さらに、コルゲート板によって補強する箇所は、外板の全体であってもよいが、台車からの振動が直接的に加わる部分、すなわち、台車が装着される台枠枕梁の位置に対して車体前後方向中央側の直近に位置する出入口引戸用戸袋部分にのみ設けることにより、少ない部品点数及び製作工数で車体全体の剛性を効果的に高めることができる。   According to the railway vehicle of the present invention, the outer plate (side structure) can be effectively reinforced by the corrugated plate joined to the inner side surfaces of the plurality of lateral bones, and the convex portion and the concave portion of the corrugated plate are continuous. By directing the direction to be directed in the vertical direction of the vehicle body, it is possible to increase the rigidity against the shearing force in the vertical direction of the vehicle body, thereby preventing out-of-plane deformation and improving the rigidity of the entire vehicle body. Further, since the thickness of the outer plate and the lateral bone can be reduced, the weight of the vehicle body and the cost can be reduced. In addition, since the corrugated plate can be joined regardless of the outer plate by joining the corrugated plate to the vehicle body inner side surface of the horizontal bone, the appearance of the outer plate is not adversely affected. In addition, by joining the outer plate and the horizontal bone by laser welding, the weld mark of the outer plate is in the longitudinal direction of the vehicle body, so that it can be finished in a good appearance by applying the same hairline finish until now. Further, the portion to be reinforced by the corrugated plate may be the entire outer plate, but the portion where vibration from the cart is directly applied, that is, the position of the frame pillow beam on which the cart is mounted By providing only in the door pocket portion for the entrance / exit sliding door located in the immediate vicinity of the center in the direction, the rigidity of the entire vehicle body can be effectively increased with a small number of parts and manufacturing man-hours.

II is a sectional view, FIG. 3 is a sectional view taken along the line III-III in FIG. 1, FIG. 4 is an exploded perspective view of an outer plate, a lateral bone and a corrugated plate, and FIG.

鉄道車両１は、左右一対の側構体２、上部の屋根構体、前後両端の妻構体と台枠とを接合して組み付けるとともに、台枠の枕梁に台車３を装着したものであって、側構体２には、複数の側窓２ａと側出入口２ｂとが設けられ、側出入口２ｂの両側で側窓２ａとの間には出入口引戸用戸袋２ｃがそれぞれ設けられている。   The railcar 1 is a structure in which a pair of left and right side structures 2, an upper roof structure, front and rear end wad structures and a frame are joined and assembled, and a carriage 3 is attached to a pillow beam on the frame, The structure 2 is provided with a plurality of side windows 2a and side doorways 2b, and doorway doors 2c for doorways are provided between the side windows 2a on both sides of the side doorway 2b.

側構体２は、外板４と、該外板４の内面に上下多段に接合される複数の横骨５と、該横骨５の車体内側面に接合されるコルゲート板６と、側窓枠７ａ及び側出入口枠７ｂとで構成されており、これらの部材は、すべてステンレス鋼で形成されている。横骨５は、平面状の中間面５ａと、該中間面５ａの幅方向両端で折り曲げられた起立面５ｂ，５ｂと、両起立面５ｂ，５ｂの幅方向端部から外側にそれぞれ折り曲げられたフランジ面５ｃ，５ｃとを備えた断面ハット型のもので、外板４の内面の所定位置に所定長さのものが車体長手方向に向かってそれぞれ配置され、フランジ面５ｃ，５ｃの長手方向に送られるレーザービームによって外板４とレーザー溶接される。   The side structure 2 includes an outer plate 4, a plurality of horizontal bones 5 that are joined to the inner surface of the outer plate 4 in multiple upper and lower stages, a corrugated plate 6 that is joined to the vehicle body inner surface of the lateral bone 5, and a side window frame 7a and the side entrance / exit frame 7b, and these members are all made of stainless steel. The lateral bone 5 was bent outward from the planar intermediate surface 5a, the rising surfaces 5b and 5b bent at both ends in the width direction of the intermediate surface 5a, and the width direction end portions of both the rising surfaces 5b and 5b. A hat-shaped cross section provided with flange surfaces 5c and 5c, with a predetermined length disposed at a predetermined position on the inner surface of the outer plate 4 in the longitudinal direction of the vehicle body, and in the longitudinal direction of the flange surfaces 5c and 5c. The outer plate 4 is laser welded by the laser beam sent.

コルゲート板６は、複数の凸状部６ａと複数の凹状部６ｂとが交互に連続して設けられた周知のもので、前記凸状部６ａと凹状部６ｂとが連続する方向（折曲線の方向）を、横骨５に直交する車体上下方向に向けて横骨５の車体内側に配置され、各横骨５の内側面となる中間面５ａに凹状部６ｂを当接させ、この当接部分が任意の接合手段で接合される。   The corrugated plate 6 is a well-known corrugated plate 6 in which a plurality of convex portions 6a and a plurality of concave portions 6b are alternately and continuously provided. The corrugated plate 6 is a direction in which the convex portions 6a and the concave portions 6b are continuous. Direction) in the vertical direction of the vehicle body perpendicular to the horizontal bone 5, the concave portion 6 b is brought into contact with the intermediate surface 5 a serving as the inner surface of each horizontal bone 5, and this contact The parts are joined by any joining means.

このように、外板４に対してその内面に複数の横骨５を接合するとともに、この横骨５の内側面に凸状部６ａと凹状部６ｂとが連続する方向を車体上下方向に向けて接合することにより、車体上下方向の剪断力に対する強度、剛性を確保することができ、面外変形を抑えて外板を効果的に補強することができる。これにより、車体全体の剛性を向上させることができる。   In this manner, the plurality of horizontal bones 5 are joined to the inner surface of the outer plate 4 and the direction in which the convex portions 6a and the concave portions 6b are continuous on the inner side surface of the horizontal bone 5 is directed in the vertical direction of the vehicle body. By joining together, it is possible to secure strength and rigidity against the shearing force in the vertical direction of the vehicle body, and to effectively reinforce the outer plate while suppressing out-of-plane deformation. Thereby, the rigidity of the whole vehicle body can be improved.

また、外板４には車体長手方向の横骨５だけを接合し、特に、横骨５の長手方向にレーザー溶接するとともに、コルゲート板６は横骨５の内側面となる中間面５ａに接合しているので、外板４の表面に溶接痕が発生しても車体長手方向に生じるため、外板４の外面に車体長手方向のヘアライン仕上げなどを施すことによって目立たなくすることができ、外板外面の見栄えが良好な側構体を得ることができる。一方、横骨５とコルゲート板６との接合は、外板４にはまったく関係なく行うことができるので、横骨５及びコルゲート板６の構造や接合位置などの条件に応じて、レーザー溶接、アーク溶接、スポット溶接などの溶接や、ボルトやリベットなどの締結手段を適宜用いることができる。   Further, only the lateral bone 5 in the longitudinal direction of the vehicle body is joined to the outer plate 4, and in particular, laser welding is performed in the longitudinal direction of the lateral bone 5, and the corrugated plate 6 is joined to the intermediate surface 5 a serving as the inner side surface of the lateral bone 5. Therefore, even if a welding mark is generated on the surface of the outer plate 4, it occurs in the longitudinal direction of the vehicle body. Therefore, the outer surface of the outer plate 4 can be made inconspicuous by applying a hairline finish in the longitudinal direction of the vehicle body. A side structure with a good appearance on the outer surface of the board can be obtained. On the other hand, since the joining of the lateral bone 5 and the corrugated plate 6 can be performed regardless of the outer plate 4, laser welding, depending on conditions such as the structure of the lateral bone 5 and the corrugated plate 6 and the joining position, Welding means such as arc welding and spot welding, and fastening means such as bolts and rivets can be used as appropriate.

さらに、コルゲート板６を車体高さ方向全体に設けることによって外板４の補強を効果的に行うことができるので、肉厚の薄いコルゲート板６を使用しても十分な剛性を確保でき、側構体の構造の簡略化が図れるとともに、外板４，横骨５及びコルゲート板６の肉厚を適正に選定することにより、車体全体の軽量化及び製造コストの低減を図ることができる。   Further, since the outer plate 4 can be effectively reinforced by providing the corrugated plate 6 in the entire vehicle body height direction, sufficient rigidity can be secured even if the thin corrugated plate 6 is used. The structure of the structure can be simplified, and by appropriately selecting the thicknesses of the outer plate 4, the lateral bone 5 and the corrugated plate 6, it is possible to reduce the weight of the entire vehicle body and reduce the manufacturing cost.

また、コルゲート板６を設けて外板４を補強する位置は、側窓２ａや側出入口２ｂを除く外板４の内側全体とすることもできるが、側窓２ａの上下の幕板部や腰板部には設けずに、車体高さ方向に連続してコルゲート板６を配置可能な出入口引戸用戸袋２ｃの部分に全高に連続するようにコルゲート板６を設けるだけでも十分な補強効果を得ることができる。さらに、側出入口２ｂの位置や開口幅などの条件によっては、すべての出入口引戸用戸袋２ｃの部分にコルゲート板６を設けることなく、荷重支持点である台枠枕梁の位置に対して車体前後方向中央側の直近に位置する出入口引戸用戸袋部分にのみ設けることも可能であり、これにより、少ない部品点数及び製作工数で車体全体の剛性を効果的に高めることができる。   Further, the position where the corrugated plate 6 is provided to reinforce the outer plate 4 may be the entire inner side of the outer plate 4 excluding the side window 2a and the side doorway 2b, but the upper and lower curtain plates and the waist plate of the side window 2a. A sufficient reinforcing effect can be obtained simply by providing the corrugated plate 6 so as to continue to the full height at the door sliding door pocket 2c where the corrugated plate 6 can be continuously arranged in the vehicle body height direction without being provided at the portion. Can do. Further, depending on conditions such as the position of the side doorway 2b and the opening width, the corrugated plate 6 is not provided in all the doorway door pockets 2c, and the front and rear of the vehicle body with respect to the position of the underframe pillow beam as the load support point It is also possible to provide only in the door pocket portion for the entrance / exit sliding door located in the immediate vicinity of the center in the direction, thereby effectively increasing the rigidity of the entire vehicle body with a small number of parts and manufacturing man-hours.

なお、前記横骨５の形状は適宜選択することができ、前述の断面ハット型の他、断面Ｚ型の部材を横骨として使用することができる。また、側窓２ａや側出入口２ｂの枠部材の組み付け、接合は従来と同様に行うことができ、これらの枠部材とコルゲート板６の両側部分との接合も任意に行うことができる。さらに、側窓２ａや側出入口２ｂの大きさ、配置数も任意である。   In addition, the shape of the said horizontal bone 5 can be selected suitably, and the cross-sectional Z-shaped member other than the above-mentioned cross-sectional hat type can be used as a horizontal bone. Further, the frame members of the side window 2a and the side doorway 2b can be assembled and joined in the same manner as before, and these frame members and both side portions of the corrugated plate 6 can be joined arbitrarily. Furthermore, the size and the number of arrangement of the side window 2a and the side entrance 2b are also arbitrary.
