[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a shipping container, particularly an assembled export container that stores machinery and the like and is loaded onto a ship.

(Prior Art) As shown in FIG. 11, a conventional shipping container has fasteners provided at the four corners of the bottom plate and the lid, and the bottom plate and
There was one in which the side plate, cover plate, and side plate were fixed with bolts.

However, due to external force applied in the horizontal direction,
The bolts of this fastener may bend, resulting in incomplete fixation of the bottom plate, lid plate, and side plate, causing problems such as wobbling.

Furthermore, it was necessary to attach the fasteners with the adjacent side panels erected, making the assembly work complicated.

(Problems to be solved by the invention) The invention is easy to assemble, and also securely fixes the side plate against external forces applied in the horizontal direction.
The aim is to provide an assembled shipping container that does not wobble.

(Means for Solving the Problems) The present invention has been made in view of the above problems, and includes a bottom plate, first side plates facing each other, and second side plates facing each other adjacent to the first side plates. It is assembled into a square box shape from the second side plate and fixed with fasteners, and the bottom plate is arranged so that the lower girder and the upper girder are placed in two different stages and are orthogonal to each other. The first side plate is for exposing the
It has a horizontal strut with a cross-sectional shape at the bottom and square vertical struts at both ends, the side surface of the vertical strut is brought into contact with the upper girder side of the orthogonal section, and the other side of the vertical strut is connected to the orthogonal section. so that it comes into contact with the side of the lower girder.
Applying the vertical support to the orthogonal part, and bringing the curved lower part of the horizontal support into contact with the end face of the upper girder of the bottom plate,
The horizontal part of the cross-shaped part is placed on the upper surface of the upper girder of the bottom plate, and the second side plate has a horizontal support with an L-shaped longitudinal section at the bottom and a vertical support at both ends, and the horizontal part of the horizontal support has an L-shaped horizontal part. The side plate is placed on the protruding part of the lower girder of the bottom plate, and is easy to assemble, and moreover, the side plate is securely fixed against external force applied in the horizontal direction and does not wobble.

(Example) The present invention will be specifically explained below with reference to an example shown in the drawings.

The assembled shipping container according to the present invention is
As shown in the figure, the bottom plate 1, first side plates 8 facing each other, and second side plates 15 facing each other adjacent to the first side plate 8 are assembled into a square box shape and fixed with fasteners. It is something that will be done.

As shown in FIG. 1, the bottom plate 1 is constructed by vertically intersecting a lower beam 2 and an upper beam 3 in two stages. As is clear from FIGS. 1 and 4, at the corners of the bottom plate 1, orthogonal portions M between the lower girder 2 and the upper girder 3 protrude. FIG. 5 is a plan view of the bottom plate 1, and as is clear from this figure, the ends of the lower beams 2 protrude from the sides of the bottom plate 1. It is desirable that a thin steel plate 4 be stretched over the top surface of the bottom plate 1.

The first side plate 8 has a horizontal support 13 with a vertical cross section at the bottom.
It has square vertical supports 9 at both ends. The lower part of the vertical support 9 projects downward from the horizontal support 13 as shown in FIG.

In addition, in the case of the example shown in the drawing, the first side plate 8 is provided with an inclined reinforcing column 11 and a horizontal column 12 at the top, and like the bottom plate 1, a thin steel plate 14 is stretched. has been done. Incidentally, in FIGS. 8 and 9, the cross-shaped horizontal support 13 is shown enlarged.
Note that the cross-shaped horizontal struts 13 also include the cross-shaped horizontal support 13.

As shown in FIG. 1, the second side plate 15 has a horizontal support 20 having an L-shape in longitudinal section at its lower part, and vertical supports 16 at both ends. The L-shaped horizontal support 20 is the first
It is shown enlarged in Figure 0. In addition, the second side plate 1
In the case of the example shown in the drawings, 5 is provided with an inclined reinforcing column 18 and a horizontal column 19 at the upper part. It is desirable that the horizontal struts 19 and 12 have a square pipe shape in terms of strength and weight reduction. Note that 5 is a cover plate.

(Function) Now, when assembling the shipping container, the vertical supports 9 of the first side plate 8 are shown in FIGS. 4 and 6.
A side surface of the upper girder 3 of the orthogonal portion M is brought into contact with the side surface B of the upper girder 3, and the other side surface of the vertical support 9 of the first side plate 8 is brought into contact with the side surface A of the lower girder 2 of the orthogonal portion M, The vertical support 9 of the first side plate 8 is connected to the orthogonal portion M
Apply to. FIG. 6 shows a state in which the vertical support 9 is applied to the orthogonal portion M. At the same time as shown in FIG. 8 before fixing and FIG. 9 after fixing, the lower part 13a of the horizontal support 13 of the first side plate 8 is connected to the upper girder 3 of the bottom plate 1. end face 3a of
At the same time, place the square-shaped horizontal part 13a on the upper surface of the upper girder 3 of the bottom plate 1. During assembly, attach the first side plate with fasteners such as screws or bolts. 8 to the bottom plate 1 for reliable fixing, but in the case of the example shown in the drawings, as shown in FIG. A through hole 30 is formed as appropriate, and a fastener 21 such as a screw or bolt passed through the through hole 30 is inserted into the upper girder 3.
It is supposed to pass through a through hole 31 (see FIG. 4) in the end surface 3a of. In this case, as shown in FIG. 9, it is desirable that the fastener 21 not protrude from the first side plate 8 from the viewpoint of occupying space during transportation.

On the other hand, when assembling the second side plate 15, as shown in FIG. The configuration is as follows. When assembling, it is preferable to fasten the second side plate 15 to the bottom plate 1 from the outside using fasteners 21 and 22 such as screws and bolts, as described above, for secure fixation. In the case of the example shown in Fig. 10, the second side plate 1
A through hole is appropriately formed in the vertical portion 20b of the L-shaped horizontal support 20 of No. 5, and a fastener 22 such as a screw or bolt passed through the through hole is fixed to the side surface of the upper girder 3 of the bottom plate 1.

In this case as well, it is desirable from the viewpoint of occupying space that the fastener 22 does not protrude from the second side plate 15 as shown in FIG. In the case of the example shown in the drawings, the vertical support 16 of the second side plate 15 has a U-shape as is clear from FIG.
6 is fitted into the square vertical support 9 of the first side plate 8 from the horizontal direction.

(Effect of the invention) As mentioned above, in the present invention, the first side plate 8
The vertical support 9 is moved so that the side surface of the vertical support 9 is brought into contact with the side surface B of the upper girder 3 of the orthogonal portion M, and the other side surface of the vertical support 9 is brought into contact with the side surface A of the lower girder 2 of the orthogonal portion M. In addition, the lower part 13a of the cross-shaped horizontal support 13 of the first side plate 8 is applied to the end face of the upper girder 3 of the bottom plate 1, and the horizontal part 1
3b is placed on the upper surface of the upper girder 3 of the bottom plate 1, the first side plate 8 can be fixed more reliably, and the first side plate 8 will not wobble.

That is, in the first side plate 8 of the present invention, as shown in FIG.
The lower part 13a of the cross-shaped horizontal support 13 contacts the end surface 3a of the upper girder 3.

Therefore, when transporting, the direction of arrow X (see Figure 1)
When an external force is applied to the side surface A, the external force is received by the side surface A and the end surface 3a of the upper girder 3, so that the first side plate 8 can be fixed more reliably. In particular, as in the example shown in FIG.
It is effective when the first side plate 8 is on the shorter side than the second side plate 15 because a large external force is easily applied to the first side plate 8 due to the rolling of the ship during transportation.

Also, if an external force is applied in the direction of arrow Y (see Figure 1) during wheel feeding, the vertical support 9 of the first side plate 8
Since this hits the side surface B of the upper girder 3 at the orthogonal portion M, the first side plate 8 is prevented from wobbling.
