JP 2005-329412 A

しかしながら、上述した鉄道車両構体では、前述のように締結具によってパネル部材を梁部材に接合するため、組立作業が煩雑になり、製造効率が低くなるという問題がある。また、近年、高い強度を有する鉄道車両構体の開発が望まれている。   However, in the above-described railway vehicle structure, the panel member is joined to the beam member by the fasteners as described above, so that the assembly work becomes complicated and the manufacturing efficiency is lowered. In recent years, development of a railway vehicle structure having high strength has been desired.

そこで、本発明は、高い強度を得ることができ且つ製造効率を高めることが可能な鉄道車両構体を提供することを課題とする。   Then, this invention makes it a subject to provide the railway vehicle structure which can obtain high intensity | strength and can improve manufacturing efficiency.

上記課題を解決するため、本発明に係る鉄道車両構体は、台枠に立設される梁部材に複数のパネル部材を接合してなる鉄道車両構体であって、梁部材には、梁部材の長手方向に沿った凹部又は該凹部に対応する凸部の一方が形成されていると共に、パネル部材には、凹部又は凸部の他方が形成されており、凸部を凹部に弾性嵌合させることによって、梁部材とパネル部材とが互いに接合されていることを特徴とする。   In order to solve the above problems, a railway vehicle structure according to the present invention is a railway vehicle structure formed by joining a plurality of panel members to a beam member standing on a frame, and the beam member includes a beam member. One of the concave portion along the longitudinal direction or the convex portion corresponding to the concave portion is formed, and the other concave portion or the convex portion is formed on the panel member, and the convex portion is elastically fitted to the concave portion. The beam member and the panel member are joined to each other.

この鉄道車両構体では、パネル部材を梁部材に接合するに際し、凸部を凹部に弾性嵌合させることで足り、締結具を用いる必要がなくなるため、組立作業が簡便なものとなる。また、このように凸部を凹部に弾性嵌合させていることから、パネル部材が梁部材から外れ難いため、パネル部材と梁部材とが互いに確実に接合される。従って、本発明の鉄道車両構体によれば、高い強度を得ることができ且つ製造効率を高めることが可能となる。   In this railway vehicle structure, when the panel member is joined to the beam member, it is sufficient to elastically fit the convex portion to the concave portion, and it is not necessary to use a fastener, so that the assembling work is simplified. Further, since the convex portion is elastically fitted to the concave portion in this way, the panel member is not easily detached from the beam member, so that the panel member and the beam member are reliably joined to each other. Therefore, according to the railway vehicle structure of the present invention, high strength can be obtained and the manufacturing efficiency can be increased.

また、パネル部材において互いに対向する一対の端部には、互いに当接することによって凸部をなす第1の突起部及び第2の突起部がそれぞれ形成されており、隣接する2つのパネル部材は、一方のパネル部材の第1の突起部と他方のパネル部材の第2の突起部とが当接してなる凸部を凹部に弾性嵌合させることによって、梁部材に接合されていることが好ましい。このように、第1の突起部と第2の突起部とが当接してなる凸部を凹部に弾性嵌合させることで、2つのパネル部材が1つの凹部によって梁部材に接合されることとなる。よって、組立作業が一層簡便なものとなり、作業効率を一層高めることができる。   In addition, a pair of end portions facing each other in the panel member are formed with a first protrusion and a second protrusion that form a protrusion by abutting each other, and the two adjacent panel members are It is preferable that the first projection of one panel member and the second projection of the other panel member are joined to the beam member by elastically fitting a projection formed by contact with the recess. As described above, the convex portion formed by the contact between the first protrusion and the second protrusion is elastically fitted to the concave portion so that the two panel members are joined to the beam member by the single concave portion. Become. Therefore, the assembling work is further simplified, and the working efficiency can be further increased.

このとき、隣接する2つのパネル部材の端部に沿って溶接部が形成されていることが好ましい。この場合、鉄道車両構体の一層高い強度を得ることができる。例えば、溶接部としては、スポット溶接又は連続溶接等が挙げられる。   At this time, it is preferable that the welding part is formed along the edge part of two adjacent panel members. In this case, higher strength of the railway vehicle structure can be obtained. For example, spot welding or continuous welding is mentioned as a welding part.

また、上記作用効果を好適に奏する構成としては、具体的には、凹部及び凸部は、梁部材の長手方向に沿って延在している構成が挙げられる。   Moreover, as a structure which shows the said effect suitably, specifically, the structure where the recessed part and the convex part are extended along the longitudinal direction of a beam member is mentioned.

また、凹部は、梁部材において車両外側を向く面に形成された第1の凹部と、車両内側を向く面に形成された第2の凹部と、を含み、第1の凹部及び第2の凹部に凸部を弾性嵌合させることによって梁部材にそれぞれ接合されたパネル部材で、車両外壁及び車両内壁が形成されていることが好ましい。この場合、車両外壁及び車両内壁の高い強度を得ることができ、且つ車両外壁及び車両内壁の製造効率を高めることが可能となる。   The concave portion includes a first concave portion formed on a surface of the beam member facing the vehicle outer side and a second concave portion formed on the surface facing the vehicle inner side, the first concave portion and the second concave portion. It is preferable that the vehicle outer wall and the vehicle inner wall are formed by panel members respectively joined to the beam member by elastically fitting the convex portions to each other. In this case, high strength of the vehicle outer wall and the vehicle inner wall can be obtained, and the manufacturing efficiency of the vehicle outer wall and the vehicle inner wall can be increased.

このとき、車両外壁と車両内壁との間には、防振材又は防音材の少なくとも一方が設けられていることが好ましい。これにより、車両の防振性や防音性も高めることができる。   At this time, it is preferable that at least one of a vibration-proof material or a sound-proof material is provided between the vehicle outer wall and the vehicle inner wall. Thereby, the vibration proof property and soundproof property of a vehicle can also be improved.

本発明によれば、高い強度を得ることができ且つ製造効率を高めることが可能となる。   According to the present invention, high strength can be obtained and the production efficiency can be increased.

次に、側構体16について詳細に説明する。側構体16では、台枠18aに連結され鉛直方向に延在する縦梁部材(梁部材)16aに、車両内側からインナパネル部材(パネル部材)16dが連結されていると共に、車両外側からアウタパネル部材(パネル部材)16cが接合されている。つまり、側構体16では、台枠18aに立設される縦梁部材16aに、複数のパネル部材4が接合されて構成されている。   Next, the side structure 16 will be described in detail. In the side structure 16, an inner panel member (panel member) 16d is connected from the vehicle inner side to a vertical beam member (beam member) 16a connected to the frame 18a and extending in the vertical direction, and an outer panel member from the vehicle outer side. (Panel member) 16c is joined. That is, the side structure 16 is configured by joining a plurality of panel members 4 to a vertical beam member 16a standing on a frame 18a.

図3は図1の鉄道車両構体における側構体の縦梁部材を示す斜視図である。図3に示すように、縦梁部材16aは、板構造体であって、車両内側に設けられたインナ部28と、車両外側に設けられたアウタ部29と、を有し、これらが互いに接合されて形成されている。   FIG. 3 is a perspective view showing a longitudinal beam member of a side structure in the railway vehicle structure of FIG. As shown in FIG. 3, the longitudinal beam member 16a is a plate structure, and has an inner portion 28 provided on the inner side of the vehicle and an outer portion 29 provided on the outer side of the vehicle, which are joined to each other. Has been formed.

インナ部28は、例えばステンレス鋼等からなる1.0〜1.5mmの厚さの金属板をプレス成形や押出・引抜成形することで形成されている。このインナ部28は、断面ハット形状を呈しており、車両外側に開口するような断面コ字状の本体板41と、この本体板41の両端のそれぞれから突出するフランジ44とを有している。本体板41は、互いに対向する側板41a,41aが底板41bを介して連続されて構成されている。   The inner portion 28 is formed, for example, by press-molding or extruding / pulling-molding a metal plate having a thickness of 1.0 to 1.5 mm made of stainless steel or the like. The inner portion 28 has a hat shape in cross section, and has a U-shaped main body plate 41 that opens to the outside of the vehicle, and flanges 44 that protrude from both ends of the main body plate 41. . The main body plate 41 is configured such that side plates 41a and 41a facing each other are continuous via a bottom plate 41b.

底板41bの車両内側の面41cには、後述の凸部46が弾性嵌合されるものとして、鉛直方向(縦梁部材16aの長手方向)に沿って延在する凹部27が形成されている。凹部27は、開口側が狭くなる(絞られる)ように設けられている。具体的には、凹部27は、凹部本体26及び開口部25を含んでいる。開口部25は、凹部本体26の開口側に段差25aを介して連続しており、凹部本体26よりも狭くなっている。   A concave portion 27 extending along the vertical direction (longitudinal direction of the longitudinal beam member 16a) is formed on the vehicle inner surface 41c of the bottom plate 41b so that a convex portion 46 described later is elastically fitted. The recess 27 is provided so that the opening side is narrowed (squeezed). Specifically, the recess 27 includes a recess body 26 and an opening 25. The opening 25 is continuous to the opening side of the concave body 26 via a step 25 a and is narrower than the concave body 26.

なお、図5(a)に示すように、ここでのインナ部28では、側板41aの車両左右方向の寸法Aは、35mmとされ、側板41a,41a間の距離Bは、50mmとされている。また、フランジ44の車両前後方向の寸法Cは、30mmとされている。凹部本体26の幅Dは、5mm以上10mm未満とされ、開口部25の幅Eは、3mm以上5mm未満とされている。また、凹部本体26の車両左右方向の寸法Fと開口部21の車両左右方向の寸法Gとは、互いに等しくされている。   As shown in FIG. 5A, in the inner portion 28 here, the dimension A in the vehicle left-right direction of the side plate 41a is set to 35 mm, and the distance B between the side plates 41a and 41a is set to 50 mm. . The dimension C of the flange 44 in the vehicle front-rear direction is 30 mm. The width D of the concave body 26 is 5 mm or more and less than 10 mm, and the width E of the opening 25 is 3 mm or more and less than 5 mm. Further, the dimension F of the concave body 26 in the left-right direction of the vehicle and the dimension G of the opening 21 in the left-right direction of the vehicle are equal to each other.

図3に戻り、アウタ部29は、上記インナ部28と同様な構成を有している。すなわち、アウタ部29は、断面ハット形状を呈しており、車両内側に開口するような断面コ字状の本体板24と、この本体板24の両端から突出するフランジ30とを有している。本体板24は、互いに対向する側板24a,24aが底板24bを介して連続されて構成されている。そして、底板24bの車両外側の面24cには、鉛直方向に沿って延在する凹部23が形成されている。凹部23は、開口側が狭くなるように設けられ、凹部本体22及び開口部21と、を含んでいる。開口部21は、凹部本体22の開口側に段差21aを介して連続しており、凹部本体22よりも狭くなっている。   Returning to FIG. 3, the outer part 29 has the same configuration as the inner part 28. That is, the outer portion 29 has a hat shape in cross section, and has a main body plate 24 having a U-shaped cross section that opens to the inside of the vehicle, and flanges 30 that protrude from both ends of the main body plate 24. The main body plate 24 is configured such that side plates 24a and 24a facing each other are connected via a bottom plate 24b. And the recessed part 23 extended along a perpendicular direction is formed in the surface 24c of the vehicle outer side of the baseplate 24b. The recess 23 is provided so that the opening side is narrow, and includes a recess body 22 and an opening 21. The opening 21 is continuous to the opening side of the concave body 22 via a step 21 a and is narrower than the concave body 22.

そして、この縦梁部材16aでは、インナ部28のフランジ44とアウタ部29のフランジ30とが互いに当接され、例えば溶接等で接合されている。これにより、縦梁部材16aにおいては、凹部27が車両内側を向く面41cに形成され,凹部23が車両外側を向く面24cに形成されることとなる。   And in this vertical beam member 16a, the flange 44 of the inner part 28 and the flange 30 of the outer part 29 are contact | abutted mutually, and are joined by welding etc., for example. Thereby, in the longitudinal beam member 16a, the concave portion 27 is formed on the surface 41c facing the vehicle inner side, and the concave portion 23 is formed on the surface 24c facing the vehicle outer side.

図4は、図1の鉄道車両構体における側構体のインナパネル部材を示す斜視図である。図2及び図4に示すように、インナパネル部材16dは、例えば0.6〜1.5mmの厚さの略平板状を呈しており、例えばステンレス鋼等で形成されている。このインナパネル部材16dは、車両前後方向に沿った板状のパネル本体43と、このパネル本体43において車両前後方向の両端部にそれぞれ設けられた突起部31,33と、を含んでいる。   4 is a perspective view showing an inner panel member of a side structure in the railway vehicle structure of FIG. As shown in FIGS. 2 and 4, the inner panel member 16 d has a substantially flat plate shape with a thickness of, for example, 0.6 to 1.5 mm, and is formed of, for example, stainless steel. The inner panel member 16d includes a plate-like panel main body 43 along the vehicle front-rear direction, and protrusions 31 and 33 provided at both ends of the panel main body 43 in the vehicle front-rear direction, respectively.

突起部31は、図4に示すように、パネル本体43の車両前後方向の一端部43aに直交(交差)すると共に車両外側に突出する基端板31aと、基端板31aの先端からパネル本体43の内側に向かって鋭角に交差する先端板31bと、を有し、断面フック状に内側に屈曲されたような板状を呈している。この先端板31bは、基端板31aとの間の角度が所定範囲内で変化するように、基端板31aとの接続箇所を基点として弾性変形可能となっている。   As shown in FIG. 4, the protrusion 31 includes a base end plate 31 a that is orthogonal to (intersects) one end 43 a of the panel main body 43 in the vehicle front-rear direction and protrudes outside the vehicle, and the front end of the base end plate 31 a from the front end 43, and a tip plate 31b that intersects at an acute angle toward the inside of 43, and has a plate shape that is bent inward in a hook shape in cross section. The distal end plate 31b is elastically deformable with the connection point with the proximal end plate 31a as a base point so that the angle between the distal end plate 31a and the proximal end plate 31a changes within a predetermined range.

なお、図5(b)に示すように、ここでのインナパネル部材16dでは、突起部31の車両左右方向の寸法Hは、凹部本体26の寸法F及び開口部25にの寸法G(図5(a)参照)の合計に応じたものとされている。また、先端板31bの車両前後方向の寸法Iは、凹部本体26の幅Dの1/2よりも若干大きいものとされている。   As shown in FIG. 5B, in the inner panel member 16d here, the dimension H in the vehicle left-right direction of the protrusion 31 is the dimension F of the concave body 26 and the dimension G of the opening 25 (FIG. 5). (See (a)). Further, the dimension I of the front end plate 31b in the vehicle front-rear direction is slightly larger than ½ of the width D of the concave body 26.

図4に戻り、突起部33は、上記突起部31と同様な構成を有している。すなわち、パネル本体43の車両前後方向の他端部43bに直交(交差)すると共に車両外側に突出する基端板33aと、基端板33aの先端からパネル本体43の内側に向かって鋭角に交差する先端板33bと、を有し、断面フック状に内側に屈曲されたような板状を呈している。この先端板33bは、基端板33aとの間の角度が所定範囲内で変化するように、基端板33aとの接続箇所を基点として弾性変形可能となっている。   Returning to FIG. 4, the protrusion 33 has the same configuration as the protrusion 31. That is, the base end plate 33a that is orthogonal to (intersects) the other end portion 43b of the panel main body 43 in the vehicle front-rear direction and projects outward from the vehicle, and intersects at an acute angle from the front end of the base end plate 33a toward the inside of the panel main body 43 And has a tip plate 33b that is bent inward in a hook shape in cross section. The distal end plate 33b is elastically deformable with the connection point with the proximal end plate 33a as a base point so that the angle with the proximal end plate 33a changes within a predetermined range.

このインナパネル部材16dは、図6に示すように、その突起部31における基端板31aが、隣接する他のインナパネル部材16dの突起部33における基端板33aと当接されている。これにより、縦梁部材16aの凹部27に対応する凸部46が、突起部31,33によって形成されることとなる。つまり、インナパネル部材16d,16dの互いに対向する一対の端部43a,43bには、互いに当接することによって凸部46をなす突起部31,33がそれぞれ形成されている。この凸部46は、車両外側に突出し、先端部が断面錨状を呈している。   As shown in FIG. 6, the inner panel member 16 d has a base end plate 31 a in the protruding portion 31 in contact with a base end plate 33 a in the protruding portion 33 of another adjacent inner panel member 16 d. Thereby, the convex part 46 corresponding to the concave part 27 of the vertical beam member 16a is formed by the projecting parts 31 and 33. That is, the pair of end portions 43a and 43b facing each other of the inner panel members 16d and 16d are formed with projections 31 and 33 that form the convex portions 46 by abutting each other. This convex part 46 protrudes to the vehicle outer side, and the front-end | tip part is exhibiting cross-sectional hook shape.

そして、インナパネル部材16dは、かかる当接状態で、その凸部46が縦梁部材16aの凹部27に嵌合されている。ここで、凸部46が凹部27に嵌合される際には、先端板31b,33bが凸部46を収縮させるように屈曲され、凸部46が開口部25を通って凹部本体26に進入される。その後、凸部46が弾性によって元の状態に戻ることで、先端板31b,33bが段差25aに係止される。これにより、図2に示すように、凸部46が凹部27にしっかりと弾性嵌合されることとなる。その結果、縦梁部材16aとインナパネル部材16dとが互いに接合され、インナパネル部材16dによって車両内壁が形成される。   And the inner panel member 16d has the convex portion 46 fitted in the concave portion 27 of the vertical beam member 16a in such a contact state. Here, when the convex portion 46 is fitted into the concave portion 27, the end plates 31 b and 33 b are bent so as to contract the convex portion 46, and the convex portion 46 enters the concave body 26 through the opening 25. Is done. Thereafter, the convex portion 46 returns to its original state by elasticity, so that the end plates 31b and 33b are locked to the step 25a. Thereby, as shown in FIG. 2, the convex portion 46 is firmly elastically fitted to the concave portion 27. As a result, the longitudinal beam member 16a and the inner panel member 16d are joined to each other, and the inner panel member 16d forms a vehicle inner wall.

アウタパネル部材16cは、上記インナパネル部材16dと同様の構成とされており、パネル本体43と突起部31,33と、を含んでいる。そして、アウタパネル部材16c,16cの突起部31,33によって凸部46が形成され、この凸部46が縦梁部材16aの凹部23に嵌合されている。これにより、凸部46が凹部23に弾性嵌合されて縦梁部材16aとアウタパネル部材16cとが互いに接合され、アウタパネル部材16cによって車両外壁が形成される。   The outer panel member 16c has the same configuration as the inner panel member 16d, and includes a panel body 43 and protrusions 31 and 33. And the convex part 46 is formed by the projection parts 31 and 33 of the outer panel members 16c and 16c, and this convex part 46 is fitted by the recessed part 23 of the vertical beam member 16a. Thereby, the convex part 46 is elastically fitted to the concave part 23, the longitudinal beam member 16a and the outer panel member 16c are joined together, and the outer panel member 16c forms a vehicle outer wall.

また、隣接する2つのアウタパネル部材16c,16cの端部43a,43b間を塞ぐように、端部43a,43bに沿って溶接部41が形成されている。ここでの溶接部41は、例えば連続溶接部とされている。なお、溶接部41は、スポット溶接部とされていてもよい。ちなみに、隣接する2つのインナパネル部材16d,16dの端部43a,43bに沿って、溶接部41が形成されていてもよい。   Moreover, the welding part 41 is formed along the edge parts 43a and 43b so that between the edge parts 43a and 43b of two adjacent outer panel members 16c and 16c may be block | closed. Here, the welded portion 41 is, for example, a continuous welded portion. The welded portion 41 may be a spot welded portion. Incidentally, the welding part 41 may be formed along the edge parts 43a and 43b of two adjacent inner panel members 16d and 16d.

また、側構体16においては、アウタパネル部材16cとインナパネル部材16dとの間(つまり、車両外壁と車両内壁との間)には、防振材42が設けられている。   Further, in the side structure 16, a vibration isolating material 42 is provided between the outer panel member 16 c and the inner panel member 16 d (that is, between the vehicle outer wall and the vehicle inner wall).

以上のように構成された鉄道車両構体10では、縦梁部材16aには、凹部23,27が形成されていると共に、パネル部材4には、凸部46が形成されており、凸部46を凹部23,27に弾性嵌合させることで縦梁部材16aとパネル部材4とが互いに接合されている。よって、パネル部材4を縦梁部材16aに接合するに際しては、凸部46を凹部23,27に弾性嵌合させることで足り、従来の鉄道車両構体のように締結具を用いる必要がなくなるため、組立作業が簡便なものとなる   In the railway vehicle structure 10 configured as described above, the vertical beam member 16a has the recesses 23 and 27, and the panel member 4 has the protrusions 46. The vertical beam member 16a and the panel member 4 are joined to each other by being elastically fitted to the recesses 23 and 27. Therefore, when the panel member 4 is joined to the longitudinal beam member 16a, it is sufficient to elastically fit the convex portion 46 to the concave portions 23 and 27, and it is not necessary to use a fastener as in the conventional railway vehicle structure. Easy assembly work

また、鉄道車両構体10では、上述したように、凸部46を凹部23,27にしっかりと弾性嵌合させている。つまり、凸部46の先端板31b,33bを凸部46が収縮されるように屈曲して、凸部46を開口部25から凹部本体22,26に進入させた後、凸部46を弾性によって元の状態に復帰させて、先端板31b,33bを凹部の段差21a,25aに係止させている。従って、パネル部材4にあっては、縦梁部材16aから外れ難く、縦梁部材16aと確実に接合されることになる。従って、鉄道車両構体10によれば、高い強度を得ることができ且つ製造効率を高めることが可能となる。   Further, in the railway vehicle structure 10, as described above, the convex portion 46 is firmly elastically fitted to the concave portions 23 and 27. In other words, the end plates 31b and 33b of the convex portion 46 are bent so that the convex portion 46 is contracted, and after the convex portion 46 enters the concave body 22 and 26 from the opening 25, the convex portion 46 is elastically moved. Returning to the original state, the end plates 31b and 33b are engaged with the stepped portions 21a and 25a of the recesses. Therefore, the panel member 4 is not easily detached from the vertical beam member 16a, and is reliably joined to the vertical beam member 16a. Therefore, according to the railway vehicle structure 10, high strength can be obtained and manufacturing efficiency can be increased.

また、本実施形態では、上述したように、パネル部材4において互いに対向する一対の端部43a,43bには、互いに当接することによって凸部46をなす突起部31,33がそれぞれ形成されており、この凸部46を凹部23,27に弾性嵌合させることによって、縦梁部材16aにパネル部材4が接合されている。よって、2つのインナパネル部材16d,16dは1つの凹部27によって縦梁部材16aに接合され、2つのアウタパネル部材16c,16cは1つの凹部23によって縦梁部材16aに接合されることとなる。よって、組立作業が一層簡便なものとなり、作業効率を一層高めることができる。   In the present embodiment, as described above, the pair of end portions 43a and 43b facing each other in the panel member 4 are formed with the projecting portions 31 and 33 that form the convex portions 46 by abutting each other. The panel member 4 is joined to the longitudinal beam member 16a by elastically fitting the convex portion 46 to the concave portions 23 and 27. Therefore, the two inner panel members 16d and 16d are joined to the vertical beam member 16a by one concave portion 27, and the two outer panel members 16c and 16c are joined to the vertical beam member 16a by one concave portion 23. Therefore, the assembling work is further simplified, and the working efficiency can be further increased.

また、本実施形態では、上述したように、隣接する2つのアウタパネル部材16c,16cの端部43a,43bに沿って溶接部41が形成されている。よって、鉄道車両構体10の一層高い強度を得ることができる。また、本実施形態のように、溶接部41を連続溶接部とすることで、車両の水密性及び気密性を高めることができる。   In the present embodiment, as described above, the welded portion 41 is formed along the end portions 43a and 43b of the two adjacent outer panel members 16c and 16c. Therefore, higher strength of the railway vehicle structure 10 can be obtained. Moreover, the watertightness and airtightness of a vehicle can be improved by making the welding part 41 into a continuous welding part like this embodiment.

また、本実施形態では、上述したように、縦梁部材16aにおいて車両外側を向く面24cに形成された凹部23に、アウタパネル部材16cの凸部46を弾性嵌合させて該アウタパネル部材16cを縦梁部材16aに接合させ、車両外壁を形成している。また、縦梁部材16aにおいて車両内側を向く面41cに形成された凹部27に、インナパネル部材16dの凸部46を弾性嵌合させて該インナパネル部材16dを縦梁部材16aに接合させ、車両内壁を形成している。よって、車両外壁及び車両内壁の高い強度を得ることができ、且つ車両外壁及び車両内壁の製造効率を高めることが可能となる。   Further, in the present embodiment, as described above, the convex portion 46 of the outer panel member 16c is elastically fitted to the concave portion 23 formed on the surface 24c facing the vehicle outer side in the vertical beam member 16a, so that the outer panel member 16c is longitudinally fitted. A vehicle outer wall is formed by joining to the beam member 16a. Further, the convex portion 46 of the inner panel member 16d is elastically fitted to the concave portion 27 formed on the surface 41c facing the vehicle inner side in the vertical beam member 16a, and the inner panel member 16d is joined to the vertical beam member 16a, thereby An inner wall is formed. Therefore, high strength of the vehicle outer wall and the vehicle inner wall can be obtained, and the manufacturing efficiency of the vehicle outer wall and the vehicle inner wall can be increased.

また、本実施形態では、上述したように、車両外壁と車両内壁との間に防振材が設けられているため、車両の防振性も高めることができる。   In the present embodiment, as described above, since the vibration isolating material is provided between the vehicle outer wall and the vehicle inner wall, the vibration isolating performance of the vehicle can be improved.

なお、本実施形態では、鉄道車両構体10の剛性をパネル部材4で積極的に受け持っており、よって、別途に柱部材等を設けることが不要とされている。   In the present embodiment, the rigidity of the railway vehicle structure 10 is positively handled by the panel member 4, so that it is not necessary to separately provide a column member or the like.

次に、本発明の第2実施形態に係る鉄道車両構体について説明する。図7は、本発明の第2実施形態に係る鉄道車両構体におけるパネル部材を示す斜視図である。本実施形態の鉄道車両構体50が上記第1実施形態の鉄道車両構体10と異なる点は、パネル部材4(図2参照)に代えて、パネル部材51を備えた点である。   Next, the railway vehicle structure according to the second embodiment of the present invention will be described. FIG. 7 is a perspective view showing a panel member in the railway vehicle structure according to the second embodiment of the present invention. The difference between the railcar structure 50 of the present embodiment and the railcar structure 10 of the first embodiment is that a panel member 51 is provided instead of the panel member 4 (see FIG. 2).

パネル部材51は、車両前後方向に沿った板状のパネル本体52を有している。また、このパネル本体52の内面52aには、縦梁部材16aの凹部23,27に弾性嵌合されるものとして、鉛直方向に沿って延在するように凸部53が設けられている。この凸部53は、上記凸部46と同様な構成を有しており、車両前後方向に沿って並設されている。   The panel member 51 has a plate-like panel main body 52 along the vehicle front-rear direction. Further, a convex portion 53 is provided on the inner surface 52a of the panel main body 52 so as to be elastically fitted to the concave portions 23 and 27 of the vertical beam member 16a so as to extend along the vertical direction. The convex portion 53 has a configuration similar to that of the convex portion 46, and is arranged in parallel along the vehicle front-rear direction.

この鉄道車両構体50においても、上記効果と同様な効果、すなわち、高い強度を得ることができ且つ製造効率を高めることが可能となるという効果が奏される。   This railcar structure 50 also has the same effect as the above effect, that is, an effect that high strength can be obtained and manufacturing efficiency can be increased.

次に、本発明の第3実施形態に係る鉄道車両構体について説明する。図8は、本発明の第3実施形態に係る鉄道車両構体におけるパネル部材を示す斜視図である。本実施形態の鉄道車両構体60が上記第2実施形態の鉄道車両構体50と異なる点は、パネル部材53(図7参照)に代えて、パネル部材61を備えた点である。   Next, a railcar structure according to a third embodiment of the present invention will be described. FIG. 8 is a perspective view showing a panel member in the railway vehicle structure according to the third embodiment of the present invention. The difference between the railcar structure 60 of the present embodiment and the railcar structure 50 of the second embodiment is that a panel member 61 is provided instead of the panel member 53 (see FIG. 7).

パネル部材61は、車両前後方向に沿った板状のパネル本体62を有している。また、このパネル本体62の内面62aには、縦梁部材16aの凹部23,27に弾性嵌合されるものとして、所定距離だけ離間されるように鉛直方向に沿って並設(ここでは、3つ)された凸部63からなる凸部ユニット64が設けられている。この凸部63は、上記凸部46と同様な構成を有している。また、凸部ユニット64は、車両前後方向に沿って複数並設されている。   The panel member 61 has a plate-like panel main body 62 along the vehicle front-rear direction. Further, the inner surface 62a of the panel main body 62 is elastically fitted to the recesses 23 and 27 of the vertical beam member 16a, and is arranged side by side along the vertical direction so as to be separated by a predetermined distance (here, 3 There is provided a convex unit 64 composed of the convex portions 63. The convex portion 63 has the same configuration as the convex portion 46. Further, a plurality of the convex unit 64 are arranged in parallel along the vehicle front-rear direction.

この鉄道車両構体60においても、上記効果と同様な効果、すなわち、高い強度を得ることができ且つ製造効率を高めることが可能となるという効果が奏される。   Also in this railway vehicle structure 60, the same effect as the above effect, that is, the effect that high strength can be obtained and the production efficiency can be increased is exhibited.

It is also possible to form recesses on the panel members, and to form projections corresponding to the recesses on the panel members of the structures 18, 12, 14, and elastically fit these projections and recesses to each other. For example, as shown in FIG. 1, in the roof structure 14, a concave portion is formed in a curved beam member (beam member) 14b that curves upward. At the same time, a projection corresponding to the recess is formed in the panel member 14a.
