PROBLEM TO BE SOLVED: To provide a railway vehicle body structure capable of maintaining a bond strength of a frame and a side body structure and reducing a number of formation of junctions.SOLUTION: A railway vehicle body structure 1 is formed by jointing a side body structure 3, a roof body structure 4, and an end body structure 5 to a frame 2. The frame 2 comprises plural transverse beams 11 extending in a width direction of a vehicle with a prescribed interval. The side body structure 3 comprises an outside plate 12 which is a side wall part of the vehicle, and a side beam 13 extending in a longitudinal direction of the vehicle on a lower end side of the outside plate 12. A lower end part 12a of the outside plate 12 comprises a junction row 51 for jointing the outside plate 12, the side beam 13 and the transverse beams 11 formed along a longitudinal direction of the vehicle. The junction row 51 comprises: first junctions 52 in which plural stages of junctions W are formed in a vertical direction; and second junctions 53 in which a number of stages of junctions W are formed in the vertical direction, the number of stages of junctions W being smaller than the number of stages of junctions of the first junctions 52. The first junctions 52 are provided on the positions of the transverse beams 11 and the second junctions 53 are provided on the positions except for the positions of the transverse beams 11.SELECTED DRAWING: Figure 2
【課題】台枠と側構体との接合強度を維持しつつ接合部の形成数を削減できる鉄道車両構体を提供する。【解決手段】台枠2に側構体3、屋根構体4、及び妻構体5を接合してなる鉄道車両構体1であって、台枠2は、所定の間隔をもって車両の幅方向に延在する複数の横梁11を備え、側構体3は、車両の側壁部をなす外板12と、外板12の下端側において車両の長手方向に延在する側梁13とを備え、外板12の下端部12aには、外板12と側梁13と横梁11とを接合する接合部列51が車両の長手方向に沿って形成され、接合部列51は、接合部Wが上下方向に複数段に形成された第1の接合部52と、接合部Wが上下方向に第1の接合部52よりも少ない段数で形成された第2の接合部53とを有し、第1の接合部52は、横梁11の位置に設けられ、第2の接合部53は、横梁11の位置を除く位置に設けられている。【選択図】図2
