Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a structure constructed by using a light alloy extruded shape material such as a railroad car, a bus, a fence type overpass, a special container, a movable house and the like.

[0002]

2. Description of the Related Art A structural structure of a vehicle or the like constructed by using a conventional light alloy extruded shape is typified by Japanese Patent Application Laid-Open No. 2-279457, and an example thereof will be described with reference to FIGS.

The side structure plates 1, 2 and 3 shown in FIG. 3 are made of a light alloy extruded profile and have a slight curvature along a cross section cut in a direction perpendicular to the front-back direction of the structure. Flanges 4, 5 and 6 that are attached to the inside of the vehicle and extend in a direction perpendicular to the cross section are erected. The flange 6 is also at the end of each side structure plate and also has a role of receiving the end of an adjacent member. An engaging portion 7 for receiving a talc member, which will be described later, is provided at the upper end of the uppermost side structure plate 3. Then, each side structure plate 1, 2, 3 is provided with flanges 4, 5, 6
Are arranged in a laminated state so that they are parallel to each other, and are joined by welding or the like.

The roof structure plates 8, 9 and 10 are similarly curved along the cross section of the structure, and a plurality of flanges 11 are provided parallel to the side structure plates 1, 2 and 3 (in the cross section) inside the vehicle. vertical)
It stands upright. And each roof structure plate 8,
9 and 10 are also connected so that the flanges 11 are parallel to each other.

However, the required rigidity cannot be obtained only by the roof structure plate and the side structure plate. Therefore, FIG. 4 and FIG.
As shown in, column members 12, 13, 14 and talc member 15
Is installed. Since the pillar member 12 has a cross section having a shape shown in FIG. 6 (A) and is provided with a curve along the lateral cross section of the structure in the longitudinal direction, each of the flanges 4 erected on the side structure plates 1 and 2 is provided. It can be contacted, the lower end is placed on the underframe 16, and the upper end coincides with the lower end of the window opening 17. A column member 13 is provided at a portion of the window opening 17, and the lower end thereof is the column member 12
It is placed on the top of the. The cross section of the column member 13 has a shape shown in FIG.

The pillar member 14 is formed to be curved along the cross section of the structure, and comes into contact with the flange 5 between the engaging portion 7 on the upper end side of the side structure plate 3 and the upper end of the pillar member 13. Is inserted. Then, each side structure plate 1, 2, 3 and pillar member 12, 1
3, 14 have their connecting portions connected by welding or the like to form a side structure A '. After this, corner pieces 18 are attached to the four corners of the window opening 17.

The talc member 15 includes roof structure plates 8, 9,
Bending along the same cross-sectional shape as 10 is provided, the end portion is inserted into the engaging portion 7, and the intermediate portion is in contact with each flange 11. The respective connecting portions of the members are connected by welding or the like to form a roof structure B ′.

The end structure C'provided at the front and rear ends of the vehicle is shown by the chain double-dashed line in FIG. 4, which is essentially the side structure A'and the roof structure B '. It is constructed similarly.

From the above, the structure structure using the conventional light alloy extruded member is composed of a hexahedron including the side structure A ', the roof structure B', the gable structure C'and the underframe 16 on both sides. Become.

[0010]

However, in the above structure structure, the talc member 15 and the pillar members 12 to 14 and the like must be curved in accordance with the cross-sectional shapes of the roof structure and the side structures. I won't. At that time, cross-sectional deformation is likely to occur on the flange of the member due to bending or pressing,
It is difficult to obtain dimensional accuracy when assembling the roof structure and side structures. or,
Since the contact between the talc member and the roof structure plate and the contact between the pillar member and the side structure plate is not directly in contact with the outer plate at the flange portion, the rigidity of the pillar member is smaller than in the conventional case. However, increasing the thickness of the talc member or the column member in order to obtain the required rigidity narrows the internal space of the structure. Furthermore, since the width of the pillar differs for each product, a new design must be made each time. Further, corners are attached to the four corners of the window by welding, but since the welded portions become stress concentration points, they are disadvantageous in structure and strength, and work such as bead finishing is troublesome.

It is an object of the present invention to solve the above-mentioned problems, to provide a structure structure which can be easily manufactured, can improve the dimensional accuracy, and can expand the space inside the structure.

[0012]

In order to achieve the above object, a structure structure of the present invention is formed of a light alloy extruded shape, has a shape along a cross section of the structure, and has an underframe of the structure. A side structure plate on which one or more flanges that are almost parallel are erected,
The side structure plate has a fitting recess into which the flange is inserted, and the pillar member is formed of a light alloy extruded shape extruded in the same direction as the side structure plate. The side structure plate is fixed to the side structure plate in a direction intersecting with the flange.

If the side structure plate is a roof structure plate for a roof and the pillar member is a talc member, a roof structure structure is obtained. Furthermore, it is desirable that the side structure structure and the roof structure structure are combined.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described with reference to FIGS. Each side structure plate 1,2,3 and roof structure plate 8,9,1
0 is the same as the conventional example.

The side structure A is formed by arranging the column members 21, 22, 23 and 24 in a line so as to intersect with the side structure plates 1, 2 and 3 and connecting the respective connecting portions by welding or the like. There is.

The column members 21 to 24 are formed of hollow light alloy extruded shape members, and are in the same direction as the side structure plates 1 and 2 (see FIG. 1A).
The sheet is extruded and formed into a long plate shape in the direction perpendicular to the paper surface), and is cut into a predetermined width and shape for use.
Further, during extrusion molding, a shape such as a curve along the shape of the cross section of the structure (the surface parallel to the paper surface of FIG. 1 (A)) is given, and further, the engaging concave portion 28 with the flanges 4 and 5 and , The connection part 29 and the like with the adjacent pillar member are also formed together. Therefore, the column member and the side structure plate can be brought into full contact with each other, and the joining force by welding can be increased. It should be noted that the reason why the shape of the cross section orthogonal to the front-rear direction of the vehicle body is matched is that the vehicle body is long in the front-rear direction and is almost straight, and the shape of this cross-section is curved. For parallel cross sections,
There is no denying that the configuration is the same as above.

The roof structure B is formed by arranging and connecting the talc members 25, 26, 27 in a row so as to intersect the roof structure plates 8, 9, 10. The talc members 25 to 27 are also made of a hollow light alloy extruded shape similar to the above-mentioned pillar members 21 to 24, and are provided with a shape such as a curve along the lateral cross section of the structure to form the engaging recess 28 of the flange 11. It Further, one talc member, for example 25, can be engaged with the flanges 11 of both of the two roof structure plates 8 and 9 so that they can be temporarily coupled to each other. By doing so, the assembly work can be facilitated. Note that this configuration is similarly applied to the pillar member 21. However, since the side structure plate has the window opening 17, it does not intersect the side structure plate at all like the column member 23, and both ends are adjacent to each other.
Some of them are supported only by 4.

Further, in the case of the column members 22 and 24, the portion corresponding to the corner metal 18 (FIG. 5) of the window opening can be formed together, so that the number of parts and the welding distortion can be reduced. Therefore, work efficiency can be improved.

Further, even if it is necessary to provide a step at the approaching portion due to structural reasons such as continuous windows, simply changing the cross-sectional shape of the pillar members 22, 23, 24 as shown in FIG. 1 (B). It does not require complicated notches or welding on columns.

In FIG. 1, the wife structure C is shown by a chain double-dashed line. As described above, the wife structure can be considered as one mode of the side structure, and the above-described side structure structure of the present invention can be applied as it is.

[0021]

As described above, according to the present invention, the pillar member and the talc member do not require bending work or press work for conforming to the cross-sectional shape of the structure. Therefore, the cross-sectional shape of the member is not deformed, and high dimensional accuracy can be obtained.

Even if the width dimensions of the talc member and the column member are different, if the structure has the same cross-sectional shape, it is not necessary to newly design a light alloy extruded shape, and only the width at the time of cutting can be changed. Get better.

Further, since the talqui member and the pillar member have the engaging portions of the flanges, they can be adhered to the roof structure plate and the side structure plate over the entire surface, thereby increasing the bonding strength and the thickness of the roof structure and the side structure. Can be thinned to make the room wider.
