Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a cargo box for a truck.

0002

[Conventional technology]

Conventionally, various cargo boxes for freight vehicles have been provided with side walls fixed to both ends of the floor plate. There is.

0003

[Problem that the idea aims to solve]

However, the bending shape of the members constituting the conventional side wall is complicated. Both have reinforcing girders, which require a large number of welding steps and are time-consuming to process.

0004 In addition, the bottom plate is usually constructed by joining two steel plates in the middle and bending both ends. Therefore, like the side wall mentioned above, there are many welding steps and processing is time-consuming.

[0005] Furthermore, since the depth of the cargo box is determined by the height of the side walls fixed to the bottom plate, Each time a different packing box is manufactured, a corresponding side wall is required, making it less versatile. There was a problem.

[0006]

[Means to solve the problem]

The freight car cargo box of the present invention is a freight car with side walls fixed to both ends of the floor plate. In this packing box, the side wall is formed into a hollow shape with a rectangular cross section by a flat plate member and a bent member. At the same time, a reinforcing material is provided in this hollow part, and a small At least, long grooves for welding are formed at the joints of the flat plate members.

[0007] In addition, the floor plate is formed of a flat plate having the same width as the inner width of the shipping box, and both ends of the floor plate are The inner surface of the side wall is welded.

[0008]

[Effect]

The side wall is formed hollow with a rectangular cross section by a flat plate member and a bent member. By providing a reinforcing material in the hollow part, the shape is simple and easy to process. . In addition, by welding the flat plate member and the reinforcing material using the long groove for welding, welding The build-up is within the long welding groove and does not protrude from the surface of the flat plate member.

[0009] Furthermore, since the inner surfaces of the side walls are welded and fixed to both ends of the floor plate, the sides to the bottom plate are fixed. By changing the welding position of the wall, it is possible to share the side wall and change the depth of the cargo box as appropriate. It becomes possible.

【Example】

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

[0011] FIG. 1 shows a cargo box for a truck according to the present invention.

0012 In FIG. 1, 1 is a cargo box of a truck. The packing box 1 has a bottom plate 2 and a bottom plate 2. Side walls 3 are fixed to the left and right ends, and a front wall (not shown) is fixed to the front end of the bottom plate 2. (omitted) and a rear wall (not shown) provided at the rear end of the bottom plate 2 so as to be openable and closable. It is formed into a box shape by a bottom plate 2, a side wall 3, a front wall, and a rear wall.

[0013] The bottom plate 2 is composed of a flat plate having the same width as the inner width of the packing box 1.

[0014] As shown in FIGS. 1 and 2, the side wall 3 is formed into a substantially U-shape with a flat plate member 31. The bent member 32 is formed into a hollow rectangular cross section, and this hollow portion A reinforcing material 33 is provided in the structure.

[0015] The center portion 33a of the reinforcing member 33 is fixed to the bending member 32 by spot welding 35. It is.

[0016] Both side portions 33b of the reinforcing member 33 are fixed to the flat plate member 31 by welding. Supplementary Long grooves 31a for welding are formed in the welded parts of the flat plate member 31 to be welded to the reinforcing material 33, respectively. It is shaped. That is, these welding long grooves 31a are arranged in the longitudinal direction of the flat plate member 31. Two rows are formed above and below at a predetermined interval. In this way, the long groove 31a for welding Welding can be automated by welding the flat plate member 31 and the reinforcing material 33 using Moreover, the weld build-up is within the long welding groove 31a and protrudes from the surface of the flat plate member 31. Can be welded cleanly without coming out.

[0017] Further, both the flat plate member 31 and the bending member 32 are fixed by welding.

[0018] By configuring the side wall 3 in this way, the shape is simple and easy to process, and the side wall There are no irregularities on the outer and inner surfaces of 3, so it looks thick and sturdy, adding to the beauty of the entire shipping box. Your perspective will also improve.

[0019] Then, as shown in FIG. The lower part of the inner surface of the side wall 3 is brought into contact and positioned at an appropriate height, and then both are welded. The side wall 3 is fixedly attached to the bottom plate 2 by further fixing.

[0020] In this way, since the side wall 3 is fixed to the bottom plate 2 by welding, the side wall 3 is fixed to the bottom plate 2 by welding. By changing the welding position of the The side walls can be shared among packing boxes 1 with different sizes, improving versatility and The number of parts can be reduced.

[0021]

[Effect of the idea]

As described above, according to the present invention, the side wall has a cross section of the flat plate member and the bent member. By forming it into a rectangular hollow part and providing a reinforcing material in this hollow part, , the shape is simple and easy to process, and there are no irregularities on the outer and inner surfaces of the side walls. It has a thick wall and looks sturdy, which improves the overall aesthetics of the shipping box.

[0022] In addition, by welding the flat plate member and the reinforcing material using the long welding groove, automatic welding can be achieved. In addition, the weld build-up is within the long groove for welding and protrudes from the surface of the flat plate member. Can be welded cleanly without coming out.

[0023] Furthermore, since the inner surfaces of the side walls are welded and fixed to both ends of the floor plate, the sides to the bottom plate are fixed. By changing the welding position of the wall, it is possible to change the depth of the packing box as appropriate, and the depth The side walls can be shared for boxes with different sizes, improving versatility and reducing the The number of items can be reduced.
