It is the schematic diagram which looked at the side part and window part of the railway vehicle from the inside of the vehicle.

  The railcar 1 includes an air conditioner (not shown) below the underframe 10 (upper floor 12) with reference to FIG. The air is blown to a conditioned air duct (not shown) provided along the X direction below the upper floor 12. Thereafter, in FIG. 6, the conditioned air is supplied to every corner of the railcar 1 via the rising duct 70 which is connected to the conditioned air duct and forms a duct module 77 which branches in the Z direction.

  The rising duct 70 is a duct having a rectangular cross section that intersects in the Z direction, and has a sufficiently high rigidity to support a later-described xero module 76. The upper end of the riser duct 70 has an overhang 70a along the X direction so that the conditioned air flowing in the Z direction inside the riser duct 70 changes its flow direction in the X direction and is supplied into the vehicle.

  Hereinafter, an operation of attaching the duct module and the xe module to a railway vehicle will be described. First, a hexahedral structure 7 including the underframe 10, the side structure 20, the roof structure 30, and the like is manufactured. In FIG. 9, a heat insulating material 74 is attached to the inside of the side structure 20 and the roof structure 30 (arrow 79a), and a duct module 77 (rise duct 70) is fixed to the heat insulating material 74 inside the vehicle (arrow). 79b). If necessary, the center of the duct module 77 in the Z-direction and the side structure 20 may be connected so that the duct module 77 does not lean inward.

  Subsequently, in the process of providing the side membrane 21 in the side structure 20, the side duct 21 covers the rising duct 70 from inside the vehicle (arrow 79c). Further, the xen module 76 is fixed to the rising duct 70 by pressing the side membrane 21 from the inside of the vehicle toward the outside of the vehicle against the rising duct 70 (arrow 79d).

  Conventionally, side interior materials corresponding to the plurality of windows 23 are provided inside the side structure 20 that constitutes the structure 7 of the railway vehicle 1, and similarly, a plurality of ceiling interior materials are provided inside the roof structure 30. I was On the other hand, according to the configuration of the present embodiment, the inside of the side structure 20 including the series of windows 23 is covered with the side film 21 which is a single material in the X direction, and the inside of the roof structure 30 is Since the material is covered with the ceiling film 31 (two in the example of FIG. 1), the number of components related to the interior material can be significantly reduced.

  Furthermore, since the plurality of side interior materials that are arranged corresponding to the conventional windows are once attached and checked for the installation state, then removed as necessary, and the work of adjusting the interval and the gap is included. In addition, many man-hours were required for the positioning work with the adjacent interior material. Similarly, a plurality of ceiling interior materials also required many man-hours for positioning adjacent ceiling interior materials. On the other hand, according to the configuration of the present embodiment, by arranging the side film 21 and the ceiling film 31 so as to bridge over them, the number of positioning steps related to the side interior material and the ceiling interior material can be significantly reduced.

  Further, since the weight per unit area of the side film 21 and the ceiling film 31 is smaller than the weight of the side interior material and the ceiling interior material made of a conventional thermoplastic resin or the like, a significant weight reduction can be realized. Furthermore, by using a part of the weight reduced by the side membrane 21 and the ceiling membrane 31, without increasing the weight of the entire vehicle, a sound insulating material (sound absorbing material) or a heat insulating material having a higher surface density is employed. Accordingly, it is possible to provide a more comfortable moving space with less noise in the vehicle.

  Conventionally, the noise generated in the interior of the railway vehicle 1 is reflected on the inner surface of the side interior material and the ceiling interior material, so that the attenuation rate is small, which hinders the reduction of the interior noise. On the other hand, according to the present embodiment, since the flexible side film 21 and the ceiling film 31 cover most of the interior of the railcar 1, the attenuation rate of the interior noise due to reflection increases, and the interior noise is reduced. Reduction can be promoted.

  As described above, according to the present embodiment, it is possible to reduce the number of parts, reduce the number of man-hours required for positioning work between the side structure and the roof structure and the interior material, and provide a railway vehicle having a lightweight interior material. can do.

  In addition, this invention is not limited to above-described embodiment, Various modifications are included. For example, the above-described embodiment has been described in detail for easy understanding of the present invention, and is not necessarily limited to one having all the configurations described. In addition, a part of the configuration of one embodiment can be replaced with the configuration of another embodiment, and the configuration of one embodiment can be added to the configuration of another embodiment. . In addition, for a part of the configuration in each embodiment, it is also possible to add, delete, or replace another configuration.
