Description

[Detailed description of the invention] The present invention relates to the structure of a railway vehicle body.

Conventionally, when attaching a gable to a roof structure/side structure assembly, as shown in FIG. It takes a lot of effort and time to align the edges, and it is troublesome to accurately match the curved surface of the roof structure 1 and the mating surface of the gable structure 3, which requires a considerable amount of correction time.

The present invention has been made in order to eliminate the above-mentioned drawbacks, and the gable structure is divided into a combed operative section and a square gable member. The upper end joints of the members are formed inward from the outer surface and approximately perpendicular to the outer surface, and the lower end joints of the gables attached to the ends of the roof structure and the longitudinal joints attached to both sides of the roof structure are formed at right angles to the outer surface. It is characterized in that the end member is attached to the side end joint portion of the side structure, which is slightly shorter in length than the roof structure, with its upper end joint portion and both sides of the inner surface of the end member in contact with the side end joint portion.

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

In FIG. 2, the roof structure 1, side structure 2, gable structure 3, and underframe 4 are manufactured separately, and the gable structure 3 is manufactured separately into a gable comb section 5 and a rectangular gable member 6.

The roof structure 1 has a gable comb section 5 fixed to the end, and side structures 2 on both sides.
are assembled integrally, and the lower ends of these side structures 2 are attached to the underframe 4.
However, the gable member 6 for the side structure 2 and the gable combing section 5
In this embodiment, the length of the roof mechanism 1 in the longitudinal direction is set slightly longer than that of the side parts 2, and the gable member 6 is attached to the gable. It is attached at a position inside the outer surface of the comb section 5 (Fig. 4).

The joining part between the cutting part 5 and the end member 6 is formed into bent parts 7 and 8 which are bent inward at 90 degrees as shown in Fig. 4, or is attached as a separate part as shown in Fig. 9. L-shaped member 17.
18, and to attach the end member 6 to the side part 2, as shown in FIGS. 3 and 5, a corner post 9 which is an L-shaped member is installed vertically at the inner end of the side part 2, The side part of the inner surface of the gable member 6 is attached via the gable comb 9, and in this case, the position of the gable member mounting surface of the corner post 9 is such that the gable member 6 can be attached to the inner side of the outer surface of the gable comb section 5. At the same time, if possible, the lower end of the end member 6 should be attached to the vertical surface of the underframe 4.
], taken on the same vertical plane as the actual component mounting surface of the underframe 4.

In addition, if the actual component mounting surfaces of the corner pillar 9 and the underframe 4 do not match, as shown in FIG. or the first
As shown in FIG. 0, it can be attached to the upper surface of the underframe 4 using a separate L-shaped member 19.

Therefore, a sealant is applied to the joints of the corner pillar 9, the side part 2, and the end member 6, and the mounting seat 1L12 with the rain gutter 10 provided from the outside of the side part 2 and the end member 6 [Fig. ], or connect with the L-shaped member 13 (Fig. 7) to cover the corner part, and apply a sealant from the outside to the joint part of the surgical part 5 and the end member 6, as shown in Fig. 4. As shown in FIG. 2, the retaining plate 14 with its upper end in contact with the bent portion 7 is fixed to the end member 6, or is further tightened, and the rain gutter 1 is attached so as to cover the retaining plate 14 at the lower part of the surgical area 5.
5 prevents rainwater from entering the joint.

Although the side end joint portion of the side portion 2 is a separate corner post 9 in the above embodiment, it may be a bent portion where the side end portion is bent inward at 90°.

As described above, in the present invention, the gable structure 3 is divided into the gable combing section 5 and the rectangular gable member 6 which is the lower part, and the lower end joint of the gable combing section 5 and the upper end joint of the gable member 6 attached thereto. Since both portions are substantially perpendicular to the outer surface, the attachment position of the gable member 6 to the gable comb portion 5 attached to the end portion of the roof structure 1 can be changed by moving it in the lateral longitudinal direction.

Therefore, even if there is an error in the lengths of the roof structure 1 and the side parts 2 in the longitudinal direction, assembly can be performed as is, and edge alignment work is not required.

In addition, the work of aligning the gable structure 3 to the roof structure 1, side portions 2, and underframe 4, which have curved surfaces, is achieved by dividing the gable structure 3 into the gable comb section 5 and the gable member 6, which improves the precision of the mating surfaces. It becomes easy.

Therefore, according to the present invention, it is possible to shorten the construction period and reduce the manufacturing cost by omitting the edge alignment work and shortening the work time to ensure the precision of the mating surfaces of the gable structure with respect to the roof structure, side parts, etc. Vehicle body assembly work can be carried out easily.

In addition, the end member 6 and the end combing part 5 and the end member 6 and the side part 2
Since a sealant is applied to the joints and then covered with another member, such as a rain gutter-shaped member, finishing treatment of the joints can be omitted, the appearance is not impaired, and watertightness is ensured. This can further increase the product value.

Furthermore, since the end member 6 can be manufactured at an appropriate time up to the final assembly process, there are fewer restrictions on the manufacturing process and the utilization rate of production equipment can be increased.
