Description

Description: TECHNICAL FIELD The present invention relates to a structure of a roof structure constituted by using a corrugated sheet roof plate in, for example, a railroad car, a bus, an enclosure overpass, and the like.

[Conventional technology]

For roofs of railway vehicles and the like, roof panels corrugated in the shape of corrugated sheets have been conventionally used (JP-A-59-1536).
No. 55, No. 57-13368, etc.), and its construction will be described with reference to FIGS. 4 to 6.

A roof plate 1 stretched over the roof of a vehicle or the like has a corrugated plate shape in which a large number of beads 1a are formed in parallel along the longitudinal direction of the vehicle and the rigidity of the roof in the longitudinal direction is increased. The walk boards 2 are connected to both sides of the roof board 1 and arranged on the roof portion of the vehicle.

On the other hand, the vehicle is provided with eaves girders 3 provided along both sides in the longitudinal direction of the vehicle and a curve along the shape of the roof, orthogonal to the eaves girders 3 and orthogonal to the longitudinal direction of the roof (roof). A large number of talc members 4 for increasing the rigidity in the width direction) and eaves girders 3
And a step board reinforcing member 5 provided in parallel with each other, and these are welded to each other to form the main structure of the roof frame. Then, the roof plate and the walk plate described above are placed on the roof structure thus configured and fixed by welding or the like to form a roof of a vehicle or the like.

In this case, according to the above-mentioned JP-A-59-153655, the bead 1a at the portion where the roof plate 1 comes into contact with the talc member 4 is eliminated to form a flat plate, thereby increasing the joint area between the talc member and the roof plate. As a result, the rigidity of the roof structure can be increased.

At the middle portion of the talc member 4, there are further provided long beam girders such as an air-conditioning duct mounting member 6 and a ceiling fluorescent lamp mounting member 7 along the longitudinal direction of the vehicle, either directly or via a connecting metal fitting 8. And indirectly fixed, and the air-conditioning duct 9, the ceiling fluorescent lamp 10, the ceiling plate 11, the wind regulating plate 12, the line delia 13 and the like are attached to these.

[Problems to be solved by the invention]

However, in the above roof structure structure, a large number of talc members 4 are required in order to secure the rigidity of the roof structure. In addition to this, since a plurality of mounting members 6 and 7 and connecting metal fittings 8 for the purpose of simply mounting ceiling mounting parts such as ducts and fluorescent lamps are required, the number of parts increases, and accordingly, Material requirements are also increased. Further, there is a problem that setup and processing time increase due to the increase in the number of parts, and the vehicle weight also increases.

The present invention has been made in order to solve the above-mentioned problems of the prior art, and provides a roof structure structure for a vehicle, which can be reduced in weight, reduced in the number of parts, and shortened in working time. It is an object.

[Means for solving the problem]

In order to achieve the above-mentioned object, the present invention is a roof structure of a vehicle using a corrugated sheet as a roof plate, wherein the roof plate has:
By arranging a plurality of beads continuously in the longitudinal direction of the roof plate, a roof plate having increased rigidity in the width direction of the roof is formed, and a plurality of longitudinal girders are installed in the longitudinal direction of the roof. A roof structure having no talc member that reinforces the rigidity in the width direction of the roof is provided by adopting a configuration in which the vertical girder supports the roof plate.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. In these figures, 20 indicates a roof plate made of a corrugated plate. This roof plate 20 has a large number of beads that are long in a direction (width direction of the roof) perpendicular to the longitudinal direction of the vehicle.
Since 20a are formed in parallel and a curved portion is provided by press working or the like in accordance with the shape of the roof as shown in FIG. 3, the rigidity of the roof plate 20 in the width direction is increased. In addition, the same walk boards 2 as in the conventional example are provided on both sides of the roof board 20.

Eaves girders 21 similar to the conventional example are provided on both sides of the vehicle, and longitudinal girders 22, 23, 24 are symmetrically installed between the eaves girders 21 and 21 on both sides from the center to both sides. Since the roof board 20 has increased rigidity in the width direction, the talque member 26 fixed by the coupling fitting 25 is provided only at the front and rear ends in the longitudinal direction of the vehicle.
These form the frame of the roof structure. This house eaves girder 21
Unlike the conventional example, does not receive the talc member, so that the size and weight can be reduced accordingly. Air-conditioning duct attachment members 27 are attached to the vertical beams 22 and 23 so as to face each other, and the air-conditioning duct 9 is attached to these members.
10 and ceiling plate 11 are attached. Further, the air conditioning plate 12 and the line delia 13 are attached between the vertical girders 22 and 23 on the most central side. That is, each stringer 22 to 24 has sufficient rigidity to receive the roof panel 20 and each facility in the room.

The roof plate 20 described above is welded to the upper portion of the roof frame to form a roof structure.

According to such a roof structure structure, the bead of the roof plate 20 is
20a is orthogonal to each vertical girder 22 to 24, and since the curved portion that matches the curved surface of the bead is formed by pressing or the like along the length of the bead 20a, the rigidity in the width direction of the roof increases, The conventional talc member 4 can be omitted.

In addition, each vertical girder 22 to 24 is a conventional duct mounting member 6
The ceiling fluorescent lamp mounting member 7 is provided with some modifications, and does not increase the number of parts.

That is, the present invention relates to a large number of beads applied to the roof plate 20.
The rigidity required for the roof structure is secured by the 20a and the curved portion, and the vertical girders 22 to 24, and at the same time, each ceiling part is directly attached to each vertical girder, which significantly reduces the number of parts in the roof structure structure. Can be reduced.

〔The invention's effect〕

As described above, according to the roof structure structure of the present invention, the roof plate and the stringers are rationally arranged to secure the required rigidity, and a large amount of talc that is specially provided in the conventional structure is provided. By eliminating the need for members, the number of parts can be reduced, the material can be saved, the setup time and the processing time can be reduced, and the weight of the product can be reduced.
