【発明の属する技術分野】
本発明は鉄道車両構体の製作方法に関する。
【０００２】
【従来の技術】
複数の中空アルミ押出し形材で構成され、主に屋根構体ブロック，側構体ブロック，台枠ブロック等よりなる鉄道車両構体は、室内側及び室外側に溶接線を有するため、両面溶接する必要がある。従来の構体製作法では、特開平６−２７０７９７号公報に記載の方法のように、例えば、室内側から溶接した場合、部材を反転して室外側を溶接する必要があった。したがって、溶接時に反転作業が入るため作業性が悪かった。
【０００３】
【発明が解決しようとする課題】
従来技術では、中空アルミ押出し形材の裏表に溶接線が生じる材料よりなる鉄道車両構体は、室内側及び室外側に溶接線を有し、両面を溶接する必要があり、部材の反転作業が入るため、作業性が悪かった。
【０００４】
本発明の目的は、中空アルミ押出し形材を用いて各構体ブロックを溶接で製作する際、部材の反転作業を伴わないように、室内側或いは室外側の片側からの溶接で容易に溶接作業を行えるような鉄道車両構体の製作方法を提供することにある。
【０００５】
【課題を解決するための手段】
上記目的は、複数の中空アルミ押出し形材（１，１´）を用いて、屋根構体ブロック，側構体ブロック，台枠ブロックよりなる鉄道車両構体を製作する方法において、前記中空アルミ押出し形材は、第１の板（１ａ）と、これに実質的に平行な第２の板（１ｂ）と、前記第１の板と前記第２の板とを接続する第３の板（１ｃ）と、からなり、前記中空アルミ押出し形材の前記第１の板（１ａ）と前記第３の板（１ｃ）との接続部から、該第１の板（１ａ）の端部までの突出部（１ａ´）は、前記第２の板（１ｂ）と前記第３の板（１ｃ）との接続部から該第２の板（１ｂ）の端部までの突出部（１ｂ´）よりも突出しており、所望の前記ブロックを製作する際に、まず、複数の中空アルミ押出し形材（１，１´）を準備し、それぞれの前記中空アルミ押出し形材の前記第１の板（１ａ，１´ａ）の前記端部同士（１ａ´，１´ａ´）を突合せ、前記第１の板が鉄道車両構体の室内側に位置する際には、前記突合せた部分を鉄道車両構体の室外側から接合し、または前記第１の板が鉄道車両構体の室外側に位置する際には、前記突合せた部分を鉄道車両構体の室内側から接合し、その後、一つの前記中空アルミ押出し形材（１）の前記第２の板（１ｂ）の前記端部（１ｂ´）と隣接する前記中空アルミ押出し形材（１´）の前記第２の板（１´ｂ）の前記端部（１´ｂ´）との間を塞ぎ形材（２）で塞ぎ、該塞ぎ形材（２）のそれぞれの端部をそれぞれの前記第２の板に溶接で接合し、該塞ぎ形材（２）の接合は、前記第１の板（１ａ，１´ａ）が室外側に位置する場合は室内側から溶接で接合し、前記第１の板（１ａ，１´ａ）が室内側に位置する場合は室外側から溶接で接合すること、によって達成できる。
【０００６】
以上のように、部材を反転せずに、片側からの溶接ですむために、溶接作業性は良好になる。
【０００７】
【発明の実施の形態】
以下、本発明の実施例について図１ないし図８を用いて説明する。
【０００８】
図１は本発明の一実施例で、中空アルミ押出し形材１，１′で構成された裏表に溶接線が生じる構体の一部を示している。図４のように、一般に鉄道車両構体は、主に左右の側構体ブロック，屋根構体ブロック，妻構体ブロック及び台枠ブロック等の構体ブロックより構成される。各構体ブロックを製作する場合、複数の中空アルミ押出し形材を作業盤上に並べ、溶接線１０を溶接でつなぎあわせていく。図１は中空アルミ押出し形材１と隣合う別の中空アルミ押出し形材１′とを塞ぎ形材２を介して溶接で溶接した状況を示している。図１、図２から明らかなように、形材１は、実質的に平行な外板１ａと内板１ｂと、両者を斜めに接続する複数の接続板である第３の板１ｃと、からなる。それぞれの接続板は外板１ａ、内板１ｂにトラス状に接続している。形材１の幅方向の端部において、外板１ａの端部は内板１ｂの端部よりも突出している。端部の接続板は突出した外板１ａの途中に接続している。内板１ｂの端部に２つの接続板が接続している。この接続部から内板１ｂの端部側に向けて板が突出している。この板の突出部は短い。この板は外板１ａ側に凹んだ位置にあり、凹部を設けている。凹部に塞ぎ形材２の端部が重なる。形材１′は形材１と同様の構成である。
【０００９】
図２は図１で示した中空アルミ押出し形材同士１，１′の溶接状況の溶接方法を示している。構体ブロックの室外側の外板１ａと外板１′ａとを突合せて溶接を行う。その後、塞ぎ形材２を構体ブロックの室内側の内板１ｂと内板１′ｂをつなぐように設置し、溶接で溶接する。その後、塞ぎ形材２を構体ブロックの室内側の内板１ｂ、内板１′ｂをつなぐように設置し、溶接で接合する。したがって、溶接作業は中空アルミ押出し形材の外板１ａ，１′ａの溶接及び内板１ｂ，１′ｂの溶接は、共に室内側からの作業ですむために、部材の反転作業も無く作業性が良い。
【００１０】
図１及び図２での溶接は室内側からの作業を示したが、室外側からでもよい。
【００１１】
図３は本発明の一実施例で側梁形材５を含む台枠ブロック３と側構体ブロック４を溶接した状況を示している。本実施例の台枠ブロック３は、図１，図２で示した方法で製作したように室内側からの溶接で組上げている。例えば、側梁形材５の外板５ａと台枠３の外板３ａとを突合せて溶接する。その後、側梁形材５の内板５ｂと台枠３の内板３ｂとを塞ぎ形材２′を介して溶接する。このように製作した台枠ブロック３と側構体４とを室内外の両面溶接で溶接する。
【００１２】
図４は図１ないし図３に示した方法で製作した側梁形材５を含む台枠ブロック３，側構体ブロック４，屋根構体６よりなる妻構体を除く車両構体を示す。
【００１３】
図５は本発明の一実施例で、側梁形材５を含む台枠ブロック３と側構体ブロック４を溶接した溶接部の状況を示している。本実施例は、台枠ブロック３に溶接された側梁形材５と側構体４の溶接作業を室内側から行った例である。即ち、側梁形材５の外板５ａと側構体４の外板４ａとを突合せて溶接する。その後、側梁形材５の内板５ｂと側構体４の内板４ｂとを塞ぎ形材２″を介して溶接する。
【００１４】
上記と同様に各ブロック同士の接合は、中空アルミ押出し形材の室内側の内板及び室外側の外板共に、室内側の溶接作業で済ますことが出来る。
【００１５】
図６は本発明の一実施例で、側梁形材５を含む台枠ブロック３と側構体ブロック４を溶接した溶接部の状況を示している。本実施例は、台枠ブロック３に溶接された側梁形材５と側構体４の溶接作業を室外側から行った例である。即ち、側梁形材５の内板５ｂと側構体４の内板４ｂとを突合せて溶接する。その後、側梁形材５の外板５ａと側構体４の外板４ａとを塞ぎ形材２″を介して溶接する。なお、側梁形材５を含む台枠ブロック３の製作は、この場合、室外側からの溶接作業で行った例を示している。
【００１６】
上記と同様に各ブロック同士の接合は、中空アルミ押出し形材の室外側の外板及び室内側の内板共に、室外側の溶接作業で済ますことが出来る。要するに、室内側からの溶接で組上げる場合は、外板を先に溶接して、その後、内板を塞ぎ形材を介して溶接し、室外側からの溶接で組上げる場合は、内板を先に溶接して、その後、外板を塞ぎ形材を介して溶接する。
【００１７】
図７は塞ぎ形材２′′が擬装部品の接合や強度上等の観点から所定の形状にしても良い。
【００２０】
【発明の効果】
本発明によれば、少なくとも各構体ブロックを製作する場合、反転作業を行わずに溶接作業ができ、作業コストが低減できる。また、本発明によれば、中空アルミ押出し形材同士の接合に、室内側から或いは室外側から溶接作業が行える。

As apparent from FIGS. 1 and 2, theprofile 1 includes a substantially parallel outer plate 1 a andinner plate 1 b, and athird plate 1 c that is a plurality of connecting plates that obliquely connect the two. Become. Each connection plate is connected to the outer plate 1a and theinner plate 1b in a truss shape. At the end in the width direction of theprofile 1, the end of the outer plate 1 a protrudes beyond the end of theinner plate 1 b. The connecting plate at the end is connected in the middle of the protruding outer plate 1a. Two connection plates are connected to the end of theinner plate 1b. A plate protrudes from the connecting portion toward the end of theinner plate 1b. The protruding part of this plate is short. This plate is in a position recessed toward the outer plate 1a, and is provided with a recess. The end of theclosing shape 2 overlaps the recess. Theprofile 1 ′ has the same configuration as that of theprofile 1.
[0009]
FIG. 2 shows a welding method in which the hollow aluminum extrudedshapes 1, 1 ′ shown in FIG. 1 are welded. Welding is performed by butting the outer plate 1a and the outer plate 1'a outside the structure block. Thereafter, theclosing shape member 2 is installed so as to connect theinner plate 1b and the inner plate 1'b on the indoor side of the structure block, and is welded by welding.Thereafter, theclosing shape member 2 is installed so as to connect theinner plate 1b and the inner plate 1'b on the indoor side of the structure block, and joined by welding. Therefore, since the welding of the outer plates 1a and 1'a and theinner plates 1b and 1'b of the hollow aluminum extruded shape is both performed from the inside of the room, workability is eliminated without reversing the members. Good.
[0010]
Although welding in FIGS. 1 and 2 shows work from the indoor side, it may be from the outdoor side.
[0011]
FIG. 3 shows a state in which theframe block 3 including the sidebeam shape member 5 and theside structure block 4 are welded in one embodiment of the present invention. Theundercarriage block 3 of this embodiment is assembled by welding from the indoor side as manufactured by the method shown in FIGS. For example, weldedtogether butt theouter plate 3a of theouter plate 5a and theunderframe 3 of Gawaharikatachizai 5. Thereafter, theinner plate 5b of theside beam profile 5 and theinner plate 3b of theframe 3 are closed and welded via the profile 2 '. Theunderframe block 3 and theside structure 4 manufactured in this way are welded by double-sided welding inside and outside the room.
[0012]
FIG. 4 shows a vehicle structure excluding a wife structure composed of aframe block 3, aside structure block 4, and a roof structure 6 including theside beam members 5 manufactured by the method shown in FIGS.
[0013]
FIG. 5 shows an embodiment of the present invention and shows a situation of a welded portion where theframe block 3 including the sidebeam shape member 5 and theside structure block 4 are welded. In this embodiment, the welding work of the sidebeam shape member 5 and theside structure 4 welded to theunderframe block 3 is performed from the indoor side. That is, weldedtogether butt and an outer plate 4a of theouter plate 5a and theside structure 4 ofGawaharikatachizai 5. Thereafter, theinner plate 5b of theside beam profile 5 and theinner plate 4b of theside structure 4 are closed and welded via theprofile 2 ″.
[0014]
In the same manner as described above, the blocks can be joined to each other by welding on the indoor side of both the inner plate on the indoor side and the outer plate on the outdoor side of theextruded hollow aluminum material.
[0015]
FIG. 6 shows an embodiment of the present invention, and shows a situation of a welded portion where theframe block 3 including theside beam members 5 and theside structure block 4 are welded. In this embodiment, the welding work of the sidebeam shape member 5 and theside structure 4 welded to theunderframe block 3 is performed from the outdoor side. That is, it weldedtogether butt theinner plate 4b of theinner plate 5b and theside structure 4 ofGawaharikatachizai 5. Thereafter, theouter plate 5a of theside beam profile 5 and the outer plate 4a of theside structure 4 are closed and welded via theprofile 2 ″. Theframe block 3 including theside beam profile 5 is manufactured in this manner. In this case, an example of performing welding work from the outdoor side is shown.
[0016]
In the same manner as described above, the blocks can be joined to each other by a welding operation on the outdoor side of both the outer outer plate and the inner inner plate of theextruded hollow aluminum material. In short, when assembling by welding from the inside of the room, the outer plate is welded first, then the inner plate is closed and welded via the shape material, and when assembling by welding from the outside of the room, the inner plate is First, the outer plate is closed and then welded via the profile.
