Description

本発明は、長土台の形状に特徴を有する鉄道車両に関する。   The present invention relates to a railway vehicle characterized by the shape of a long base.

鉄道車両は、屋根構体、側構体、台枠及び妻構体が互いに接合されて車両用構体が構成されている。そのうち側構体と台枠との接合部分は、例えば図12に示すような構造を有している。車体表面となる外板101には、内側に縦骨102が接合され、そうした外板101の下端には、断面がいわゆるZ形をした長土台103が車体長手方向に接合されている。この長土台103は、車両用構体を構成する際、薄い平板である外板101の裾部のねじれを防止したり、構体結合時の溶接熱によるひずみを低減させるために設けられている。   In a railcar, a roof structure, a side structure, a frame, and a wife structure are joined together to form a vehicle structure. Among them, the joint portion between the side structure and the underframe has a structure as shown in FIG. 12, for example. A longitudinal bone 102 is joined to the outer plate 101 on the surface of the vehicle body, and a long base 103 having a so-called Z-shaped cross section is joined to the lower end of the outer plate 101 in the longitudinal direction of the vehicle body. The long base 103 is provided in order to prevent the skirt of the outer plate 101 that is a thin flat plate from being twisted and to reduce distortion due to welding heat when the structure is joined when the vehicle structure is formed.

従来の長土台103は、図示するようないわゆるZ形形状をしており、外板101下端の裾部に沿って接合されている。そのため、上方に向けて開口した隙間110が形成され、断面ハット形の縦骨102が、その隙間110に差し込まれるようにして下端部分が挿入されている。側構体と台枠とは、長土台103が接合された外板101の裾部と側梁104とが接合され、その側梁104には床板105が接合されている。更に、この接合部分には床板105に断面L字形のホルダ106が接合され、また縦骨102にも断面コの字形の補強骨107が重ねて接合され、ホルダ106と補強骨107がガセット108によって連結されている。
特開2007−153106号公報
The conventional long base 103 has a so-called Z shape as shown in the figure, and is joined along the bottom of the lower end of the outer plate 101. Therefore, a gap 110 opened upward is formed, and the lower end portion is inserted so that the longitudinal bone 102 having a hat-shaped cross section is inserted into the gap 110. The side structure and the base frame are joined to the hem of the outer plate 101 to which the long base 103 is joined and the side beam 104, and the floor plate 105 is joined to the side beam 104. Furthermore, a holder 106 having an L-shaped cross section is joined to the floor plate 105 at this joined portion, and a U-shaped reinforcing bone 107 is joined to the longitudinal bone 102 so that the holder 106 and the reinforcing bone 107 are joined by a gusset 108. It is connected.

ところで鉄道車両は、開閉扉が出入りする側構体の戸袋部に雨水などが浸入するため、内部に水が溜まらないように戸袋の底部に水抜き孔が形成されている。この点、図12に示す構造では、長土台103によって上方に開口した隙間110が形成されているため、そこに水が溜まらないように水抜き孔へと流れる構図がとられている。例えば図13に示すように、外板201と長土台203との間にできた隙間にエポキシ樹脂の詰め物211が入れられ、ウレタン系樹脂のシール材212が設けられている。従って、戸袋部に浸入した水は、傾斜したシール材212表面を滑って溝部213に落ち、不図示の水抜き孔を通って排水される。しかし、こうした構造の鉄道車両は、わざわざ長土台203に詰め物211を入れなければならず、組立において煩雑な作業であった。   By the way, in a railcar, since rainwater and the like enter the door pocket portion of the side structure where the opening and closing door enters and exits, a drain hole is formed in the bottom portion of the door pocket so that water does not collect inside. In this regard, in the structure shown in FIG. 12, since the gap 110 opened upward is formed by the long base 103, the composition flows into the drain hole so that water does not accumulate there. For example, as shown in FIG. 13, an epoxy resin filling 211 is placed in a gap formed between the outer plate 201 and the long base 203, and a urethane resin sealant 212 is provided. Accordingly, the water that has entered the door pocket slides on the inclined sealing material 212 surface and falls into the groove 213 and is drained through a drain hole (not shown). However, the railway vehicle having such a structure has been troublesome in assembling because the padding 211 has to be put in the long base 203.

そこで、本発明は、かかる課題を解決すべく、長土台における排水のための煩わしい作業を不要にした鉄道車両を提供することを目的とする。   Accordingly, an object of the present invention is to provide a railway vehicle that eliminates the troublesome work for drainage on the long base in order to solve such a problem.

本発明の鉄道車両は、外板の車内面側に骨部材が車体高さ方向と車体長手方向の縦横に接合された側構体を台枠と接合するに際し、前記外板の裾部に長土台を接合し、その外板と長土台との接合部分を側梁に当てて接合させるものであって、前記長土台は、前記外板の裾部に重ねられるフランジ部と、そのフランジ部と接合した前記側梁の上方に位置する立体部とを備え、その立体部が、前記外板に接して閉じる形状で形成されたものあることを特徴とする。   The railcar according to the present invention has a long base at the hem of the outer plate when the side structure in which the bone member is bonded to the vehicle inner surface side of the outer plate in the vehicle body height direction and the vehicle body longitudinal direction is joined to the base frame. And the joint portion between the outer plate and the long base is applied to a side beam to join the flange portion, and the long base is joined to the flange portion of the outer plate, and the flange portion is joined to the flange portion. And a three-dimensional portion positioned above the side beam, and the three-dimensional portion is formed in a shape that closes in contact with the outer plate.

また、本発明の鉄道車両は、前記側構体では複数の縦骨が前記横骨と長土台の上に重ねて接合され、その縦骨の下端部分に対し、前記側梁に対して立設された内骨が接合されたものであることが好ましい。
また、本発明の鉄道車両は、前記側構体の戸袋部には、前記長土台の立体部から前記長土台の上面及び前記内骨にかけて薄膜のシール材が設けられ、排水溝が形成されたものであることが好ましい。
In the railcar of the present invention, in the side structure, a plurality of vertical bones are overlapped and joined to the horizontal bone and the long base, and the lower end portion of the vertical bone is erected with respect to the side beam. It is preferable that the inner bone is joined.
In the railcar of the present invention, a thin seal material is provided on the door pocket portion of the side structure from the three-dimensional portion of the long base to the upper surface of the long base and the inner bone, and a drainage groove is formed. It is preferable that

よって、本発明によれば、長土台の立体部上方を閉じるように形成したため、従来例のように水抜きのための詰め物を入れる手間が省け、組み立て作業が簡素化される。また、その後のメンテナンスでも詰め物の取り換えなどが不要となり、その点でも手間を省くことができる。そして、こうした長土台は、構体組み立て時に外板の裾部を補強する他、組み立て後も構体の剛性を高めるための骨部材として機能する。   Therefore, according to this invention, since it formed so that the solid part upper part of a long base might be closed, the effort which puts the filling for draining like a prior art example is saved, and an assembly operation is simplified. In addition, it is not necessary to replace the stuffing in the subsequent maintenance, and this can save time. Such a long base functions as a bone member for reinforcing the rigidity of the structure after the assembly, in addition to reinforcing the skirt of the outer plate at the time of the structure assembly.

次に、本発明に係る鉄道車両の一実施形態について図面を参照しながら以下に説明する。図1は、本実施形態の鉄道車両を構成する側構体を示した図である。この鉄道車両は、ステンレス製構体であって、その側構体1が構体ブロックなどのパーツを接合して組み合わされた車両用構体によって構成されている。車両用構体は、側構体1の上部に屋根構体が、前後には妻構体がそれぞれ接合され、更にその下には台枠が接合されている。側構体1は、2つの車端窓ブロック2と中間窓ブロック3、そして窓ブロック2,3の間に3つの側入口ブロック4が接合されている。車端窓ブロック2や中間窓ブロック3は、例えば上下に分けられた上部外板と下部外板との接合によって側外板が形成され、その車体内側には剛性を保つため骨部材などが接合されている。   Next, an embodiment of a railway vehicle according to the present invention will be described below with reference to the drawings. FIG. 1 is a view showing a side structure constituting the railway vehicle of the present embodiment. This railway vehicle is a stainless steel structure, and its side structure 1 is constituted by a vehicle structure in which parts such as a structure block are joined and combined. In the vehicle structure, the roof structure is joined to the upper part of the side structure 1, the wife structure is joined to the front and rear, and the underframe is joined to the bottom structure. In the side structure 1, two vehicle end window blocks 2, an intermediate window block 3, and three side entrance blocks 4 are joined between the window blocks 2 and 3. In the vehicle end window block 2 and the intermediate window block 3, for example, a side outer plate is formed by joining an upper outer plate and a lower outer plate which are divided into upper and lower parts, and a bone member or the like is joined to the inside of the vehicle body to maintain rigidity. Has been.

次に図2は、中間窓ブロックを車内側から表した図であり、両端には接合された側入口ブロック4が示されている。中間窓ブロック3は、外板11に骨部材を接合して構成されている。図3乃至図5は、そうした構造が分かりやすいように、それぞれ中間窓ブロックの腰部、吹寄せ部、幕部を横方向に切った図2のA−A断面、B−B断面そしてC−C断面を示した図であり、図6は、腰部を縦方向に切った図2のD−D断面図である。   Next, FIG. 2 is a view showing the intermediate window block from the vehicle inner side, and the side inlet blocks 4 joined to each other are shown. The intermediate window block 3 is configured by joining a bone member to the outer plate 11. 3 to 5 are cross-sectional views taken along the lines AA, BB, and CC in FIG. 2 in which the waist portion, the blowing portion, and the curtain portion of the intermediate window block are cut in a transverse direction so that such a structure can be easily understood. FIG. 6 is a cross-sectional view taken along the line DD in FIG. 2 with the waist section cut in the longitudinal direction.

中間窓ブロック3は、厚さ2mmのステンレス製の外板11に対し、厚さ1.5mmステンレス製板材から形成された補強部材である横骨12と、更にその上に縦骨13が接合されている。なお、以下の説明において、特定の横骨12又は縦骨13を他のものと区別する場合には、a,b…の符号を付して示す。横骨12及び縦骨13は、そのほとんどが図6に示すように、断面がコの字に折り曲げられた立体部301と、その両側に張り出したフランジ部302が連続したハット形状をしたものである。   The intermediate window block 3 has a lateral bone 12 that is a reinforcing member formed of a stainless steel plate material having a thickness of 1.5 mm, and a vertical bone 13 further joined thereto on a stainless steel outer plate 11 having a thickness of 2 mm. ing. In the following description, when a specific transverse bone 12 or longitudinal bone 13 is distinguished from other bones, a, b... As shown in FIG. 6, the horizontal bone 12 and the vertical bone 13 are each formed in a hat shape in which a three-dimensional portion 301 whose cross section is bent in a U shape and flange portions 302 projecting on both sides thereof are continuous. is there.

本実施形態では、例えば図6に示すように、横骨12が外板11に直接接合され、その横骨12に重ねて縦骨13が接合されている。横骨12は、外板11に重ねられたフランジ部302に沿うようにレーザ溶接が行われ、縦骨13は、そのフランジ部302が横骨12の立体部301に重ねられ、その重なった部分にレーザ溶接が行われる。本実施形態では、骨部材の接合にレーザ溶接が使用されるが、接合手段としてはレーザ溶接の他、スポット溶接や栓溶接を使用してもよい。また、本実施形態でも部分的には栓溶接なども使用されている。   In this embodiment, for example, as shown in FIG. 6, the lateral bone 12 is directly joined to the outer plate 11, and the longitudinal bone 13 is joined to the lateral bone 12 so as to overlap. The horizontal bone 12 is laser-welded so as to follow the flange portion 302 overlapped with the outer plate 11, and the vertical bone 13 is overlapped with the three-dimensional portion 301 of the horizontal bone 12, and the overlapping portion Laser welding is performed. In this embodiment, laser welding is used for joining the bone members, but as the joining means, spot welding or plug welding may be used in addition to laser welding. Also in this embodiment, plug welding or the like is partially used.

腰部では、図2に示すように、4本の横骨12が外板11に接合され、その横骨12の上には、窓開口部21の下の4本の縦骨13aと、窓開口部21の左右の縦辺に沿って2本の縦骨13bが接合されている。そして、最上部の横骨12bは、上方に延びたフランジ部311が形成され、その先端には車内側に折り曲げられたヘリ曲部311aが形成され、窓開口部21の窓枠剛性が高められている。側外板を構成する上部外板11と下部外板11との境目Pがこのフランジ部311の高さにあり、上部に分割された外板11は段差のない車体表面になるように構成されている。   At the waist, as shown in FIG. 2, four horizontal bones 12 are joined to the outer plate 11, and on the horizontal bone 12, four vertical bones 13 a below the window opening 21 and a window opening. Two vertical bones 13 b are joined along the left and right vertical sides of the portion 21. The uppermost lateral bone 12b is formed with a flange portion 311 extending upward, and a helicopter portion 311a bent at the inner side of the vehicle is formed at the tip thereof, so that the window frame rigidity of the window opening 21 is enhanced. ing. The boundary P between the upper outer plate 11 and the lower outer plate 11 constituting the side outer plate is at the height of the flange portion 311, and the outer plate 11 divided into the upper portion is configured to be a vehicle body surface without a step. ing.

一方、外板11の裾部には長土台14が接合され、下側のフランジ部14aが下端を揃えるようにして重ねられている。本実施形態の長土台14は、断面がハット形の骨部材と同様に立体部14bとフランジ部14a,14cが形成されている。そこで、横骨12に重ねられた縦骨13がこの長土台14にも重ねて接合されている。長土台14は本来、車両用構体の組み立てに際して側構体の薄い平板である外板11の裾部のねじれ防止や、構体結合時の溶接熱による側構体の外板11のひずみを低減させる目的で設けられている。しかし、本実施形態では骨部材として車両用構体の剛性を高める役割も果たしている。   On the other hand, a long base 14 is joined to the skirt portion of the outer plate 11, and a lower flange portion 14a is overlapped so that the lower ends thereof are aligned. The long base 14 of this embodiment has a three-dimensional portion 14b and flange portions 14a and 14c formed in the same manner as a hat-shaped bone member. Therefore, the vertical bone 13 superimposed on the horizontal bone 12 is also overlapped and joined to the long base 14. The long base 14 is originally intended to prevent twisting of the skirt portion of the outer plate 11 which is a thin flat plate of the side structure when assembling the vehicle structure, and to reduce distortion of the outer plate 11 of the side structure due to welding heat when the structure is joined. Is provided. However, in this embodiment, it also plays a role of increasing the rigidity of the vehicle structure as a bone member.

長土台14は、下方のフランジ部14aが外板11の端部に揃うように幅広で形成され、その2層に重ねられた部分が側梁17に沿って張り合わせるようにして接合されている。そして、側梁17の上に位置する長土台14の立体部14bは、断面が台形形状であって車体上側が傾斜面になっている。従って、本実施形態の長土台14は上方が閉じられているため、中に水が溜まってしまうようなことがなく、戸袋部に浸入した水は、傾斜面に沿って側梁17の上面17aに落ちるようになっている。その側梁17には不図示の水抜き孔が形成され、接続された排水管によって水が排水されるようになっている。   The long base 14 is formed wide so that the lower flange portion 14 a is aligned with the end portion of the outer plate 11, and the two overlapping layers are joined so as to stick together along the side beam 17. . And the three-dimensional part 14b of the long base 14 located on the side beam 17 is a trapezoidal cross section, and the vehicle body upper side is an inclined surface. Therefore, since the long base 14 of the present embodiment is closed at the upper side, water does not accumulate therein, and the water that has entered the door pocket portion is the upper surface 17a of the side beam 17 along the inclined surface. To fall. A drain hole (not shown) is formed in the side beam 17 so that water is drained by a connected drain pipe.

ところで、側梁17には内骨19が突き立てられるように突設され、縦骨13に対して当てられている。この内骨19は、図2に示すように帯状に形成され、中間窓ブロック3の両端の縦骨13cに接合され、当接したその間の縦骨13にも接合されている。いずれも接合は栓溶接が行われている。そして、本実施形態では、例えば図7に示すように薄膜のシール材41を用いて排水溝40が形成されている。すなわち、図2に示す縦骨13b,13cの間の戸袋部において、長土台14から側梁17の上面17a、そして内骨19に至るまでシール材41が設けられ、そのシール材41によって断面がUの字になった排水溝40が形成される。   By the way, the side beam 17 is provided so as to protrude the inner bone 19 and is applied to the longitudinal bone 13. The inner bone 19 is formed in a band shape as shown in FIG. 2, joined to the longitudinal bones 13 c at both ends of the intermediate window block 3, and also joined to the longitudinal bones 13 in between. In both cases, plug welding is performed. In this embodiment, for example, as shown in FIG. 7, the drainage groove 40 is formed using a thin seal material 41. That is, the sealing material 41 is provided from the long base 14 to the upper surface 17a of the side beam 17 and the inner bone 19 in the door pocket portion between the vertical bones 13b and 13c shown in FIG. A drainage groove 40 having a U-shape is formed.

シール材41によって構成された排水溝40は、排水管43が接続された水抜き孔42に向けて傾斜して取り付けられている。そのため、戸袋部に浸入した水は、長土台14の閉じられた上方の傾斜面に沿って側梁17の上面17aに落ち、排水溝40をスムーズに流れて水抜き孔42から排水管43を通って外に排水される。なお、こうしたシール材41を設けない図6に示すような構造であっても、側梁17の上面17a自体に傾斜を設けることで内骨19に沿って水が流れて水抜き孔42から排水できる。   The drainage groove 40 constituted by the sealing material 41 is attached to be inclined toward the water drain hole 42 to which the drainage pipe 43 is connected. Therefore, the water that has entered the door pocket part falls on the upper surface 17a of the side beam 17 along the closed upper inclined surface of the long base 14, flows smoothly through the drainage groove 40, and drains the drain pipe 43 from the drain hole 42. It drains out through. Even if such a structure as shown in FIG. 6 without the sealing material 41 is provided, the upper surface 17a of the side beam 17 is inclined so that water flows along the inner bone 19 and drains from the drain hole 42. it can.

よって、本実施形態では、立体部14bを台形にしたハット形の長土台14にしたため、従来例のように水抜きのための詰め物を入れる手間が省け、組み立て作業が簡素化された。また、その後のメンテナンスでも詰め物の取り換えなどが不要となり、その点でも手間を省くことができるようになった。そして、こうした長土台14は、構体組み立て時に外板11の裾部を補強する他、組み立て後も構体の剛性を高めるための骨部材として機能するようになった。   Therefore, in this embodiment, since the three-dimensional part 14b is the hat-shaped long base 14 having a trapezoidal shape, it is possible to save the trouble of putting the padding for draining as in the conventional example, and the assembly work is simplified. In addition, it is no longer necessary to replace the stuffing in subsequent maintenance, and it is possible to save time and effort. And such a long base 14 came to function as a bone member for improving the rigidity of a structure after an assembly other than reinforcing the bottom part of the outer plate 11 at the time of a structure assembly.

次に、図8は、中間窓ブロック3の左側端部を示した図3の一部拡大図である。側入口ブロック4との連結部分であり、側入口フレーム18が外板11の外側に重ねて接合されている。外板11の内側には縦骨13cが接合されているが、この縦骨13cは、立体部301の側面と片側のフランジ部302に切欠き131(図2参照)が複数形成され、横骨12の先端の端部が挿入されている。縦骨13cの接合は、外板11に当てられたフランジ部302のレーザ溶接によって行われるが、表面側には側入口フレーム18があるため、縦方向の溶接痕が車体表面に現れることはない。   Next, FIG. 8 is a partially enlarged view of FIG. 3 showing the left end portion of the intermediate window block 3. It is a connecting portion with the side inlet block 4, and the side inlet frame 18 is overlapped and joined to the outside of the outer plate 11. The longitudinal bone 13c is joined to the inner side of the outer plate 11. The longitudinal bone 13c has a plurality of notches 131 (see FIG. 2) formed on the side surface of the three-dimensional portion 301 and the flange portion 302 on one side, thereby forming a lateral bone. The end of 12 tips is inserted. The longitudinal bone 13c is joined by laser welding of the flange portion 302 applied to the outer plate 11. However, since the side entrance frame 18 is on the surface side, no longitudinal welding mark appears on the surface of the vehicle body. .

続いて、中間窓ブロック3の幕部には、図5に示すように、外板11に対して横骨12dが直接接合され、その上に縦骨13が重ねられて接合が行われる。図9は、幕部を示した図2のE−E断面図である。図示するように、外板11には横骨12が接合され、その上端部に横骨12dのフランジ部302と屋根構体8の端部が重ねられて接合されている。一方、幕部における最下部の横骨12eは、下方に延びたフランジ部313が形成され、その先端には内側に折り曲げられたヘリ曲部313aが形成され、窓開口部21の窓枠剛性が高められている。   Subsequently, as shown in FIG. 5, the transverse bone 12 d is directly joined to the outer plate 11 at the curtain portion of the intermediate window block 3, and the longitudinal bone 13 is overlapped thereon to join. FIG. 9 is a cross-sectional view taken along the line EE of FIG. 2 showing the curtain portion. As shown in the drawing, the lateral bone 12 is joined to the outer plate 11, and the flange portion 302 of the lateral bone 12 d and the end portion of the roof structure 8 are overlapped and joined to the upper end portion thereof. On the other hand, the lowermost horizontal bone 12e in the curtain portion is formed with a flange portion 313 extending downward, and a helicopter portion 313a bent inward is formed at the tip thereof, and the window frame rigidity of the window opening 21 is increased. Has been enhanced.

次に、せん断力のかかりやすい吹寄せ部には、図2に示すように、補強部材としてシアプレート31が張り合わされている。このシアプレート31は、板厚2mmの外板11に対し、厚さ1.5mmのステンレス鋼板あって、窓開口部21の左右両側に設けられている。シアプレート31は、吹寄せ部全体に重なる大ききであって、特に窓開口部21の窓隅部R1〜R4の周りに沿うように突起部31aが上下に形成され、その窓隅部R1〜R4を補強する形状になっている。   Next, as shown in FIG. 2, a shear plate 31 as a reinforcing member is attached to the blowing portion where shearing force is easily applied. The shear plate 31 is a stainless steel plate having a thickness of 1.5 mm with respect to the outer plate 11 having a thickness of 2 mm, and is provided on both the left and right sides of the window opening 21. The shear plate 31 is large enough to overlap the entire blowing portion, and in particular, a protrusion 31a is formed vertically so as to extend around the window corners R1 to R4 of the window opening 21, and the window corners R1 to R4 are formed. It is shaped to reinforce.

吹寄せ部では、こうしたシアプレート31の上から骨部材を接合した構成になっている。そして、シアプレート31によって剛性を高めているため、中間の縦骨13を省略した構造になっている。吹寄せ部は、図4に示すように、外板11にシアプレート31が重ねられてレーザ溶接によって接合されているが、横骨12と同様に車体横方向にレーザを走らせて接合される。そうしたシアプレート31に対し、横骨12fがレーザ溶接によって接合され、その両端部に縦骨13b,13cが接合されている。縦骨13bは、片側を長くして段差のついた一方のフランジ部314がシアプレート31に当てられて接合されている。この場合、縦方向にレーザ溶接を行っても、シアプレート31が間にあるため、外板11の表面に縦方向の溶接痕は現れない。   In the blowing part, the bone member is joined from above the shear plate 31. Since the rigidity is enhanced by the shear plate 31, the intermediate longitudinal bone 13 is omitted. As shown in FIG. 4, the blowing portion is joined by laser welding with the shear plate 31 overlapped on the outer plate 11, but is joined by running a laser in the vehicle body lateral direction in the same manner as the lateral bone 12. The transverse bone 12f is joined to such a shear plate 31 by laser welding, and the longitudinal bones 13b and 13c are joined to both ends thereof. The longitudinal bone 13b is joined by making one side longer and having one stepped flange portion 314 applied to the shear plate 31. In this case, even if laser welding is performed in the vertical direction, since the shear plate 31 is in between, no vertical welding mark appears on the surface of the outer plate 11.

外板11は、端部が応力を受けて変形し易いため、外形線に沿って骨部材を接合するなどして強度を確保しているが、本実施形態では、窓開口部21の窓枠に沿って起立したヘリ曲部が形成されている。そこで、シアプレート31には、窓開口部21の形状に沿って図4に示すようにヘリ曲部31bが形成されている。更に、窓開口部21の上下にも同様にヘリ曲部が形成されている。ここで図10及び図11は、窓隅部R1或いはR2を示した図であり、いずれも図(a)は図2の一部拡大図であり、図(b)はその横方向断面図である。   Since the outer plate 11 is easily deformed due to stress at the end portion, the strength is ensured by joining bone members along the outer shape line. In this embodiment, the window frame of the window opening 21 is secured. A helicopter erected along the line is formed. Therefore, a helicopter 31b is formed in the shear plate 31 along the shape of the window opening 21 as shown in FIG. Furthermore, helicopter portions are similarly formed above and below the window opening 21. Here, FIGS. 10 and 11 are views showing the window corners R1 or R2, both of which (a) is a partially enlarged view of FIG. 2, and (b) is a transverse sectional view thereof. is there.

図10に示す窓開口部21の下の腰部には、横骨12bが外板11に接合され、そこに内骨16が車内側へ突き出すように(図6参照)接合されている。内骨16は、その端部がガセット25によって縦骨13bと栓溶接によって接合されている。横骨12bは、窓開口部21側のフランジ部311が上方に延び、先端が折り曲げられたヘリ曲部311aになっている。フランジ部311は、シアプレート31の突起部31aと干渉しないように切り欠かれ、フランジ部311のヘリ曲部311aと、シアプレート31のヘリ曲部31bは、窓開口部21の枠形状に沿って連続している。そして、フランジ部311とシアプレート31とはガセット32によって連結され、そのガセット32にもヘリ曲部32aが形成されている。なお、こうした構造は窓開口部21において左右対称に形成され、右側の窓隅部R4にも同様に構成されている。   The lateral bone 12b is joined to the outer plate 11 at the lower portion of the lower portion of the window opening 21 shown in FIG. 10, and the inner bone 16 is joined thereto so as to protrude toward the vehicle interior (see FIG. 6). The end of the inner bone 16 is joined to the longitudinal bone 13b by a gusset 25 by plug welding. The horizontal bone 12b is a helicopter 311a in which the flange 311 on the window opening 21 side extends upward and the tip is bent. The flange portion 311 is cut out so as not to interfere with the projection portion 31 a of the shear plate 31, and the helically curved portion 311 a of the flange portion 311 and the helically curved portion 31 b of the shear plate 31 are along the frame shape of the window opening 21. Are continuous. The flange portion 311 and the shear plate 31 are connected by a gusset 32, and the gusset 32 also has a helicopter portion 32a. In addition, such a structure is formed symmetrically in the window opening 21 and is similarly configured in the right window corner R4.

次に、図11に示す窓開口部21の上の腰部には、横骨12eが外板11に接合され、そこに内骨26が重ね合わせて接合されている(図9参照)。内骨26には切欠き部が形成され、そこに縦骨13bの端部が挿入されて接合されている。横骨12eは、窓開口部21側のフランジ部315が延び、先端が折り曲げられたヘリ曲部315aになっている。フランジ部315は、シアプレート31の突起部31aと干渉しないように切り欠かれ、フランジ部315のヘリ曲部315aと、シアプレート31のヘリ曲部31bは、窓開口部21の枠形状に沿って連続している。そして、フランジ部315とシアプレート31とはガセット33によって連結され、そのガセット33にもヘリ曲部33aが形成されている。なお、こうした構造は窓開口部21において左右対称に形成され、右側の窓隅部R3にも同様に構成されている。   Next, the lateral bone 12e is joined to the outer plate 11 at the waist above the window opening 21 shown in FIG. 11, and the inner bone 26 is joined to the outer plate 11 (see FIG. 9). A cutout is formed in the inner bone 26, and the end of the longitudinal bone 13b is inserted and joined thereto. The horizontal bone 12e is a helicopter 315a in which the flange 315 on the window opening 21 side extends and the tip is bent. The flange portion 315 is cut out so as not to interfere with the projection portion 31 a of the shear plate 31, and the helically bent portion 315 a of the flange portion 315 and the helically bent portion 31 b of the shear plate 31 follow the frame shape of the window opening 21. Are continuous. The flange portion 315 and the shear plate 31 are connected by a gusset 33, and the gusset 33 also has a helicopter portion 33a. In addition, such a structure is formed symmetrically in the window opening 21 and is similarly configured in the right window corner R3.

よって、鉄道車両の吹寄せ部は強度不足によって外板面へのシワが発生し易いが、本実施形態では吹寄せ部にシアプレート31を重ねて剛性を高めることで強度不足を補っている。特に、窓開口部21の窓隅部R1〜R4に対して突起部31を形成して補強しているため、高い応力が発生する箇所も十分に強度を確保することができている。更に、窓開口部21の窓隅部R1〜R4を含む枠形状に沿って、シアプレート31のヘリ曲部31bや骨部材のフランジ部311,315のヘリ曲部311a,315aが形成されているため、この点でもより剛性を高めた構成になっている。従って、側構体に面積の大きい窓開口部21が形成された鉄道車両であっても、車体剛性を向上させて面外変形に対する強度を増加させることができる。また、窓開口部21の枠形状に沿って周状にヘリ曲部31b,311a,315aが形成されているため、これが窓周囲のシールだまりを兼ねることもできる。   Therefore, the blowing portion of the railway vehicle is likely to be wrinkled on the outer plate surface due to insufficient strength, but in this embodiment, the lack of strength is compensated by increasing the rigidity by overlapping the shear plate 31 on the blowing portion. In particular, since the projections 31 are formed and reinforced with respect to the window corners R1 to R4 of the window opening 21, the strength where the high stress is generated can be sufficiently ensured. Furthermore, along the frame shape including the window corners R1 to R4 of the window opening 21, the helicopter 31b of the shear plate 31 and the helicopters 311a and 315a of the flanges 311 and 315 of the bone members are formed. Therefore, in this respect as well, the structure is more rigid. Therefore, even in a railway vehicle in which the window opening 21 having a large area is formed in the side structure, the rigidity against the out-of-plane deformation can be increased by improving the rigidity of the vehicle body. Further, since the helicopter portions 31b, 311a, and 315a are formed in a circumferential shape along the frame shape of the window opening 21, this can also serve as a seal pool around the window.
