Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a structure for a railway vehicle. [Prior Art] Conventionally, as shown in Fig. 2, in the structure of a railway vehicle, a plurality of side pillars 4 are erected on side beams 3, 3 on both sides of a platform 2 disposed at the bottom of a car body 1. A curtain plate belt 5 and a waist belt 6, which serve as transverse bones, are arranged in the longitudinal direction of the vehicle body on these side pillars 4.4 to form side grooves, and the upper parts of the side pillars 4.4 are connected to long bamboos 7.4 in the longitudinal direction of the vehicle body. 7, connect the long bamboos 7 and 7 with multiple tarukis 8, 8 to form a roof structure, and rivet the outer panel 9 on the outside of the gutter and the roof board 10 on the outside of the roof structure. Alternatively, the structure is such that the rigidity of the vehicle body 1 is maintained by the gutter and roof structure, the outer panel 9, and the roof plate 10, which are stretched by spot welding or the like.

(Problem to be solved by the invention) Incidentally, the presence or absence of distortion in the outer skin is a factor that greatly affects the appearance of a vehicle, but in the case of conventional structures, in order to avoid bearing the load on the outer skin, It is necessary to firmly connect the outer panels, and there are various distortion factors such as irregular arrangement of the frame, rivet heads, spot welding impressions, arc welding heat effects, etc., and the body assembly work requires skill. Work processes such as the process of removing distortion required time and effort.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a railway vehicle with an excellent appearance, in which the rigidity of the vehicle body is borne by the structural frame, the work for attaching the outer panels is simplified, the work process is shortened, and the work process is shortened.

[Means for solving problems]

In order to achieve the above object, the present invention provides a structure for a railway vehicle having a structure frame formed by arranging a plurality of longitudinal columns and a plurality of horizontal frames in a direction perpendicular to the longitudinal columns. A structure frame is formed by arranging braces in a rectangular space formed by the frame and the transverse bones, and an outer panel is stretched over the structure frame.

[For production]

By configuring in this way, the structure frame can be assembled firmly and the structure can be made such that stress is borne only by the structure frame.

〔Example〕

An embodiment of the present invention will be described below with reference to FIG.

The figure shows the side gutter of the car body. A plurality of vertical side pillars 21 are erected on the side beams 20, and on the upper part of these side pillars 21 there is a curtain plate belt 22 which becomes a horizontal frame, and in the middle part there is a waist belt 23. are arranged respectively, and adjacent side columns 21.21 and side beams 20. Waist belt 23
Braces 2 are provided in the rectangular space 24 formed by the curtain plate belt 22.
5 is provided as a reinforcing member to form a structure frame, and the outer panel is stretched over this structure frame.

With this configuration, the structure frame can be assembled firmly and the structure can have sufficient strength even without a skin panel, and since there is no need to firmly connect the skin panel to the structure frame, distortion of the skin panel can be avoided. It is possible to prevent this from occurring, improve the appearance, shorten the vehicle assembly process, and since no stress is placed on the outer panel, it is possible to freely select the material for the outer panel.

Although the above embodiment describes an example in which the present invention is applied to a street gutter, it is also possible to apply the present invention to each block such as a roof structure, a nine-frame structure, etc. A structure may be formed by combining the present invention with a part of the structure.

〔Effect of the invention〕

As described above, the present invention arranges braces in the rectangular space of the vehicle structure frame formed by the vertical columns and the horizontal ribs, so that the structure frame is firmly assembled, and the stress is borne only by the structure frame. Because of this structure, there is no need to strengthen the mounting of the outer panel, which prevents the occurrence of distortion, simplifies the outer panel installation work and shortens the work process, and also allows the material of the outer panel to be freely selected. Therefore, it can be made into a railway vehicle with an excellent appearance.
