Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a structure forming a car body for a railway vehicle.

[Conventional technology]

A conventional structure for a railway vehicle is constructed by combining separately formed structures such as a floor structure, an underframe, a steel bridge, a gable structure, and a roof structure into a box shape.

゛Each of the above-mentioned structures consists of a respective frame and a respective outer plate attached to the frame.The outer plate is also considered as a bullet hole member and is designed to share the load.When assembling each structure, the frame and outer plate are They were firmly joined by welding, etc.

[Problem that the invention seeks to solve]

However, in the above-mentioned method, in order to firmly join the frame and the outer panel to obtain bullet holes in the structure, it is necessary to have a sufficiently large weld layer at the joint part, which requires a large number of man-hours and also causes thermal distortion due to welding. However, as a post-process, it was necessary to remove distortions from the outer panels, which required a huge amount of knowledge.

In particular, steel bridges are formed by using one outer panel that continues in the longitudinal direction of the vehicle body and joining multiple side columns to the outer panel, so installing the outer panel requires skill. Distortion was easily noticeable.

Furthermore, since the vehicle body is assembled after each structure has been assembled separately, it is necessary to transport the structure, and the work is troublesome, especially on long steel bridges.

Furthermore, when repairing or modifying the car body after it is completed, special consideration must be taken to maintain strength when cutting or adding parts to the outer skin.

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 is provided by the frame constituting the structure, the work of removing 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 includes a plurality of vertical members,
A frame is formed by joining a plurality of horizontal members that intersect a with this frame, and an l+1 outer panel unit is fitted into a rectangular space formed by being surrounded by Yn vertical members and horizontal members of the frame. It is characterized in that it is fixed by mechanical bonding.

(Function) Therefore, a vehicle with an excellent appearance can be easily manufactured without causing thermal distortion to the outer panel.

〔Example〕

Hereinafter, an embodiment in which the present invention is applied to a steel bridge will be described based on the drawings.

The steel bridge 1 is composed of a frame 2 and an outer plate unit 3 attached to the frame 2.

The frame 2 includes a side beam 5B which is a horizontal member made of a hollow member with a square cross section, similar to the side columns 4a and 4b which are a plurality of vertical members made of a hollow member with a square cross section.

5b are orthogonally arranged at predetermined positions on a standardized jig device and firmly joined by welding or the like, and are formed to have the necessary rigidity against external forces.
a, 6b, and 6c are formed with predetermined sizes.

The outer panel units 3 installed in the rectangular spaces 6a, 6b, and 6c are wide window units 3a and entrance/exit door frame units 3b depending on their respective purposes.

and narrow door pocket unit j-3C, small wall unit 3d.

The driver's cab door frame unit 30 and the like are located in the rectangular space (3a).

6b and 5c, except for the double door frame units 3b and 3e. 8, 8, using honeycomb etc. as a core material to create a lightweight and durable structure, and both door frame units 3
b, 3e, the inner side of the four-periphery frame 7 is used as a frame portion for a door.

In addition, the glass 9 of window glass 3a is made of H rubber 10. It is attached to the window unit 6a via a crosspiece 11 and a horizontal rib 12.

A rectangular space 6 into which the entrance/exit door frame unit 3b is inserted.
The side pillars 4b on both sides of C are made of members with small expected dimensions in order to provide a path for opening and opening the door, and the reinforcing plates 13
is stretched on the inside to increase rigidity. Further, the door pocket unit 3C inserted into the rectangular space portions 6b on both sides of the entrance/exit door frame unit 3b is also formed to be thin like the side pillars 4b.

After the frame 2 formed as described above is attached to other structures to form a cylindrical vehicle body, the outer panel unit 3 is formed into rectangular spaces 5a, 6b, 5c, and apply structural adhesive 14 to the outer flange portions 7b of the four-frame frame 7 to the side columns 4a, 4b and the side beams 5a, 5b.
It is mechanically fixed and attached using rivets 15 or screws, etc., with the parts in between.

In this way, a frame is formed by joining a plurality of vertical members and a horizontal member, and separately formed outer plate units are inserted into the plurality of rectangular spaces formed in the frame to mechanically connect them. Since it is firmly fixed, the fabrication of the frame and the fabrication of the outer skin unit can be carried out separately and in parallel, and it is also possible to easily create a vehicle with an excellent appearance without causing thermal distortion to the outer skin unit.
11, it is possible to omit the work of removing distortion after manufacturing the body structure, which was required in the past, and the time required for manufacturing and assembling the vehicle can be shortened.

In addition, by providing the frame with the necessary rigidity for the structure and mechanically connecting the grains, it is possible to use a material that is easy to work with for the eaves as the material for the outer panel, reducing the weight of the vehicle and making it possible to select design options, etc. The width of the vehicle body has been expanded to allow a variety of vehicle body shapes by 4!1, and it has become easier to repair and replace it.

Furthermore, if the width dimensions of the wide unit and the narrow knit are formed at a ratio of 2=1, and the spacing between the pillars of the frame and the width of the outer panel unit are standardized, it is possible to determine whether the vehicle has a driver's cab or not. It is possible to easily deal with differences in the number of entrance and exit doors, etc., and to easily manufacture vehicles of various shapes.

In addition to steel bridges, the present invention can also be applied to frames such as floor structures, gable structures, and roof structures.

(Effects of the Invention) As described above, in the railway vehicle structure of the present invention, a plurality of vertical members and horizontal members are joined to form a frame, and an outer plate unit is installed in a rectangular space formed in the frame. Since the outer panels are inserted and fixed by mechanical connection, it is easy to attach the outer panels, and a vehicle with an excellent appearance can be obtained without causing thermal distortion to the outer panels.

In addition, since no strength is placed on the outer panel unit, it is easier to manufacture the outer panel unit, which expands the range of materials and designs that can be selected, making it possible to manufacture lightweight vehicles with a variety of designs.Furthermore, the outer panel unit can be easily repaired or replaced. It becomes easier.
