  The present invention relates to a railway vehicle structure that is assembled by joining a roof structure, a side structure, and the like, and more particularly, to a railway vehicle structure that eliminates a step at a joint portion between the roof structure and the side structure.

  The railway vehicle is composed of a railway vehicle structure in which a side structure is joined to the left and right sides along the longitudinal direction of the underframe, a wife structure is joined before and after the side structure, and a roof structure is joined to the upper part. An example of such a railway vehicle structure is disclosed in Japanese Patent Application Laid-Open No. 2003-191842 proposed by the present applicant. This is a vehicle having a stainless steel structure, and is a railway vehicle structure having a structure in which parts such as side structure blocks are joined and combined. FIG. 8 is a side view of the railway vehicle structure disclosed in the publication.

  In the railway vehicle structure 100, a roof structure 102 is joined to the upper part of the side structure 101, and a lower part of the side structure 101 is joined to the underframe 103. The side structure 101 for one vehicle described in the publication that constitutes such a railway vehicle structure is located between two sets of vehicle end window blocks 111, three sets of intermediate window blocks 112, and each of the window blocks 111, 112. The four side inlet blocks 113 are joined to each other. Each of the blocks 111 to 113 is created by attaching a side outer plate to a framework. A roof structure 102 is placed on and joined to the side structure 101 formed by joining the blocks 111 to 113. FIG. 9 is a cross-sectional view showing a joint portion between the side structure 101 and the roof structure 102.

The roof structure 102 is provided with a plurality of rafters 122 extending in the vehicle body width direction on the lower surface of the roof outer plate 121. The roof skin 121 is formed in a corrugated shape at the center in the vehicle body width direction, and is formed in an outer shape so as to be separated from the rafters 122 at the corners at both ends in the width direction. Is formed over the entire length. In such a roof structure 102, the end portion of the rafter 122 is joined to the long girder 125, and the column 127 of the side structure 101 is joined to the long girder 125. At this time, the roof outer plate 121 is overlapped from the outer side with respect to the side outer plate 128 of the side structure 101 with the outer side of the flange 123 curved and lowered downward, and the end portion 124 being vertical. And the part in which the outer plates overlapped is joined by spot welding.
Japanese Patent Laying-Open No. 2003-191842 (page 2-3, FIG. 2) JP-A-5-4579 (FIG. 1)

However, in the conventional railway vehicle structure, as described above, the roof outer plate 121 of the roof structure 102 is overlapped and joined to the side outer plate 128 of the side structure 101 from the outside, so that there is a step in that portion, and the appearance It was not good looking.
On the other hand, Patent Document 2 discloses a structure in which a ridge as shown in FIG. 10 is formed at a joint portion between a roof structure and a side structure. Specifically, the roof outer plate 211 of the roof structure 201 is bent at the end in the width direction so as to form a flange 212, and the side outer plate 213 of the side structure 202 is bent of the roof outer plate constituting the flange 212. It is overlapped and joined to the part from the outside. Accordingly, in such a railway vehicle structure, a step between the roof outer plate 211 and the side outer plate 213 does not appear on the side surface of the side structure 202, but the presence of the eaves 212b can be well confirmed by passengers standing at the platform, and looks good in that respect. Was not good.

  Further, when the overlapping portion of the roof outer plate 121 and the side outer plate 128 is joined by spot welding, a watertight treatment using a sealing material is further required at the joined portion. However, the seal material at the joint portion needs to be replaced due to deterioration over time, or when the compatibility with the detergent used for car washing is poor, the seal is deteriorated, and replacement for that is also necessary. Therefore, in the conventional railway vehicle structure, the maintenance related to the sealing material between the side structure 101 and the roof structure 102 is troublesome.

  Accordingly, an object of the present invention is to provide a railway vehicle structure in which a step and a fence formed at a joint portion between a side structure and a roof structure are not visible to passengers standing at the platform.

A railway vehicle structure according to the present invention is formed by joining a side structure, a roof structure, a wife structure, and a frame, and the side structure is curved at an upper portion thereof and extends to the roof structure side. A step between the side structure and the roof structure, which is joined to the end of the roof structure at a low position by the connection plate and connected to the end of the vehicle body in the longitudinal direction of the vehicle body, forms a fence. Features.
Moreover, the rail vehicle structure according to the present invention is preferably such that the side structure, the roof structure and the connection plate are continuously welded by MIG welding or TIG welding.

  By the way, in the railway vehicle structure of this embodiment, as can be seen from FIG. 1 and FIG. 2, the upper part of the side structure extends to the roof structure side (not shown) and is curved. Therefore, the intermediate window block 10 and the side entrance block 20 similarly have a curved shape with the outer plates 11 and 25 upward. In the intermediate window block 10, a joint member 35 is provided along the curved shape of the outer plate 11 on the extension of the side column 12 and the curtain frame 15, and in the side entrance block 20, A joint member 36 along the curved shape of the outer plate 25 is provided at a comb tooth portion along the line 24b. The curved surface portion is provided with reinforcing members 37 and 38 having a hat-shaped cross section in the longitudinal direction so as to connect the joint members 35 and 36 respectively.

  Here, FIG. 6 is a cross-sectional view showing a curved portion of the upper part of the side structure, that is, the upper part of the outer plate. The outer plate 11 (the same applies to the outer plate 25) is curved at the upper portion as shown in the figure, and the connecting plate 41 is joined to the flat portion 11a ahead. The connection plate 41 is a long plate material having a length corresponding to one vehicle, and both ends in the width direction are bent in opposite directions to form folded ends 41a and 41b. The connecting plate 41 is used to connect the side structure formed by joining the vehicle end, the intermediate window block, and the side entrance block to the roof structure.

  At this time, one folding end 41a is joined from below to the flat portion 11a at the upper end of the outer plate 11, and the other folding end 41b is joined with the end of the roof-side connecting plate 43 placed thereon. Accordingly, the connecting portion between the side structure 1 and the roof structure 2 is formed with a step so that the end of the roof structure is positioned lower than the end of the curved side structure. In the railway vehicle structure of the present embodiment, the step formed by the step surface 41c of the connection plate 41 thus becomes a rod 42 that collects and passes water so that the rain that has fallen on the roof does not reach the passengers at the platform. This saddle 42 is located at the tip of the curved portion at the top of the vehicle body and is in a position where its presence is not known even when the passenger sees the vehicle from a home or the like.

A rafter 45 is provided between the roof side connection plate 43 and the fastener 44 joined to the folded end 41b so as to insert the tip, and the roof outer plate in which the central part in the vehicle body width direction is formed in a corrugated shape. 46 is joined to the roof-side connecting plate 43 and disposed on the rafter 45.

Each part which comprises the railway vehicle structure comprised as mentioned above is joined as follows. First, the intermediate window block 10 and the side entrance block 20 are contacted with the left and right vertical sides of the entrance frame 21 with respect to the vehicle body inner surface of the outer plate 11, and are continuously welded from the outside of the vehicle body by a laser.
The intermediate window block 10 includes an upper outer plate 11A including an outer plate 11 including a curtain plate portion and a lower outer plate 11B including a waist plate portion. Has been. Therefore, the upper outer plate 11A and the lower outer plate 11B are abutted against each other, and the joining line 18 that appears at the height of the window opening 10 is joined by continuous welding with a laser.

  And the joining of the side structure 1 and the roof structure 2 is the welding connection of the outer plate 11 and the roof side connection plate 43 which were piled up on the connection board 41 and the folding ends 41a and 41b. Specifically, the corner p1 between the front end of the outer plate 11 and the connection plate 41 shown in FIG. 6 and the corner p2 between the front end of the roof side connection plate 43 and the connection plate 41 are continuously welded. Here, the laser is used like the entrance frame 21 and the outer plate 11 described above, and continuous welding is performed, and since the finish is not visible to the passenger, post-treatment of the bead is unnecessary, and therefore continuous MIG welding or TIG welding is used. You may make it join to. Further, other joints are appropriately joined by laser welding or the like.

Therefore, according to the railway vehicle structure of the present embodiment, the side structure 1 is curved and extends toward the roof structure 2 side, and the end of the side structure 1 is in a position that cannot be seen from the passenger standing on the platform. And since the side structure 1 is joined at that position via the roof structure 2 via the connection plate 35, the joint portion cannot be seen. Since it cannot be confirmed, it looks better. Moreover, since the joint part of the side structure 1 and the roof structure 2 is in a position that cannot be seen by the passengers, it is necessary to post-process the bead that can be formed even if the part is continuously welded by MIG welding or TIG welding. It is easy to process.
Further, by continuously welding such as MIG welding, TIG welding, and laser welding, it is possible to ensure the water tightness of the joint, eliminating the need for the sealing material required for spot welding, No maintenance is required to replace the material.
