Description

  The present invention relates to a railway vehicle structure.

  Currently, a technology related to a railway vehicle structure that constitutes the body of a railway vehicle has been proposed. The railway vehicle structure includes a pair of side structures that constitute the side surfaces of the body of the railway vehicle, and a roof structure that constitutes the roof of the body of the railway vehicle. The side structure and the roof structure have a metal outer plate and a reinforcing member (frame) joined to the back surface of the outer plate. In recent years, various techniques related to a railway vehicle structure in which a rainwater discharge rod is formed at a joint portion between a side structure and a roof structure have been proposed (see, for example, Patent Document 1).

Japanese Patent Laid-Open No. 10-1047

  However, in the conventional rail vehicle structure 100 with a collar as shown in FIG. 4, the collar 120 protrudes outward in the vehicle width direction from the outer plate 111 constituting the side structure 110, so that the appearance of the body of the railway vehicle is impaired. There was a problem that would be.

  The present invention has been made in view of such a situation, and provides a railway vehicle structure that can improve the appearance of the railway vehicle without protruding a ridge from the outer plate of the side structure outward in the vehicle width direction. The purpose is to do.

  In order to achieve the above object, a railway vehicle structure according to the present invention comprises a pair of side structures constituting the side surface of a railway vehicle, and a roof structure constituting a roof of the railway vehicle. A side outer plate formed so as to rise substantially vertically; a beam member disposed on the vehicle inner side of the side outer plate and extending in the vehicle longitudinal direction and attached below the upper end of the side outer plate by a predetermined dimension; The saddle placement portion is formed by the side outer plate and the beam member. The roof structure has a roof outer plate formed so as to be gradually inclined downward from the roof top to both ends in the vehicle width direction, and is substantially horizontal by bending both ends in the vehicle width direction of the roof outer plate. A ridge having a horizontal portion extending in a vertical direction and a vertical portion rising substantially vertically from the horizontal portion is formed. Then, the side structure and the roof structure are coupled by spot welding the side outer plate and the vertical part of the fence in a state where the roof structure is mounted on the side structure mounting section. It will be.

  When such a configuration is adopted, the roof structure ridge is placed on the side structure ridge placement portion formed by the side skin that rises substantially vertically and the beam member disposed on the vehicle interior side of the side skin. be able to. Therefore, since the eaves can be arranged on the vehicle interior side of the side structure and the eaves do not protrude outward from the side outer plate, the appearance of the railway vehicle can be improved. Moreover, since the side outer plate is formed of a substantially vertical surface, the interior volume can be increased and the passenger capacity can be increased. Further, the beam member attached to the side outer plate can suppress the deformation of the side structure when the side structure and the roof structure are coupled, and can increase the bending rigidity of the entire railway vehicle structure. In addition, the roof structure ridge is placed on the side structure ridge mounting section, and the side skin and the vertical section of the ridge are fastened by spot welding, so the side structure and the roof structure can be joined very easily. be able to.

  In the railway vehicle structure according to the present invention, the side outer plate and the vertical portion of the eave can be fastened in a state where the upper end portion of the side outer plate and the upper end portion of the vertical portion of the eave are aligned at substantially the same height. .

  By adopting such a configuration, the end portion of the side structure (upper end portion of the side skin) and the end portion of the roof structure (upper end portion of the vertical portion of the eaves) can be aligned at the upper portion, so that these both end portions are covered. Thus, it is possible to close the joint between the side structure and the roof structure simply by applying the waterproofing agent. Accordingly, it is possible to increase the water tightness of the joint portion, reduce the application range of the waterproofing agent at the joint portion, and reduce the time and labor required for vehicle manufacture.

  Further, in the railway vehicle structure according to the present invention, a cross-section hat-shaped beam member in which plate-shaped flange portions are connected to both ends of a columnar portion having a U-shaped cross section is employed, and the surface of the flange portion is a side outer plate. The beam member can be attached to the side outer plate while being in contact with the inner surface of the plate.

  When such a configuration is adopted, the beam member is a hat having a cross-sectional shape, and the beam member is formed on the side outer plate in a state where the surface of the flange portion of the beam member is in contact with the inner surface of the side outer plate (the vehicle inner side surface). Since it is attached, the bending rigidity of the structure can be further increased.

  In the railway vehicle structure according to the present invention, one of the flange portions of the beam member is sandwiched between the side outer plate and the vertical portion of the eaves, and the side outer plate, the flange portion of the beam member, and the vertical portion of the eaves are combined. It can also be fastened by spot welding.

  When such a configuration is adopted, the side outer plate, the flange portion of the beam member, and the vertical portion of the flange can be fastened together by spot welding, so that the number of steps in manufacturing the vehicle can be reduced.

  In the railcar structure according to the present invention, the columnar part of the beam member and the horizontal part of the eaves (for example, by indirect spot welding) with the eaves of the roof structure placed on the eaves placement part of the side structure. ) Can be fastened.

  When this configuration is adopted, the columnar portion of the beam member and the horizontal portion of the eaves are fastened, so that the side structure and the roof structure can be more firmly coupled.

  Further, in the railway vehicle structure according to the present invention, a coupling member for coupling the side structure and the roof structure is attached to the inner surface of the side skin, and a transverse beam extending in the vehicle width direction is attached to the inner surface of the roof skin. The coupling member and the cross beam can be fastened (for example, by a hack bolt or spot welding) in a state where the roof of the roof structure is placed on the side of the side structure.

  When such a configuration is adopted, since the coupling member attached to the side outer plate and the cross beam attached to the roof outer plate are fastened, the side structure and the roof structure can be more firmly connected.
