2. Description of the Related Art A shipping container made of steel sheet used for transportation of automobile parts is constructed by standing panels on four edges of a quadrangular floor member equipped with base legs and connecting both sides of each panel. The side wall is formed in a box shape. Among the panels that make up the side walls, the panel that is parallel to the base leg is called the gutter panel, and the panel that is orthogonal to the base leg is called the toe panel. We are making shipping containers.

In the closed type transportation container, as shown in FIG. 24, both the saw panel (3A) and the nail panel (3B) are
Posts (4A) and (4B) and upper stiles (5A) and (5
B) and lower stiles (6A) and (6B) are attached to corrugated steel sheets (7A) and (7B) on the outer frame, and when assembled, for example, the toe panel (3B) The pillar (4B) is fitted and positioned to the pillar (4A) of the saw panel (3A). Further, the grip member (8A) (8B) is provided on the floor member (2) provided with a plurality of base legs (1), and the grip panel (3A) and the toe panel ( 3B) is retained.

As the above-mentioned transportation container, there is a glass panel (3
A) and the toe panel (3B) are made of corrugated steel sheet, and in addition to the closed-type transport container, a gaw panel (3
There is also a crate type (watermark structure) transport container (hereinafter referred to as a crate container) in which A) and the toe panel (3B) are formed only by a frame without corrugated steel plates.

[0005]

In the conventional shipping container,
Since the columns (4A) and (4B) provided on the gutter panel (3A) and the toe panel (3B) are fitted together,
Positioning is easy at the time of assembly, and the load applied to the upper panel (3A) and the tab panel (3B) from above when the transport containers are stacked and used is applied to the columns (4A) and (4B) provided for each. It is highly rigid. Further, the floor member (2), the saw panel (3A), and the toe panel (3)
It is safe without separation from B).

However, in the above structure, the columns (4A) (4A)
B) has a double structure, and two kinds of grip fittings (8A) and (8B) are used to prevent it from coming off. Since the number of parts is large, the weight is very heavy and the cost is high. Also in the crate container configured for weight reduction, even if the corrugated steel plates (7A) and (7B) are omitted to reduce the weight, the weight is still heavy and the cost is high.
It was desired to further reduce the number of parts.

Further, it is desired to develop a corner metal fitting which enhances the rigidity of the corner portions of the upper ends of the combined girder panel (3A) and toe panel (3B) and which can be easily attached to and detached from the transportation container.

The present invention is intended to provide a steel plate transport container which has a small number of parts, is light in weight, is easy to assemble, and has high rigidity, and a corner metal fitting used for the steel plate transport container.

Further, the corner fitting forms a supporting projection for supporting the base legs of the upper transportation containers when the transportation containers are stacked, and a deformation preventing rib for pressing the upper wall against bending is formed on the oblique side of the upper wall (upper stile). It is formed along the side that does not touch .

In order to prevent the corner fitting from coming off, an engaging portion that engages with the upper stile of the first panel and the second panel is formed on the side wall, or an engaging portion that engages with and engages with the slit of the upper stile. A protrusion is formed on the portion to engage with the upper stile.

[0013]

In the above-mentioned steel plate transport container, the vertical wall of the corner support provided on the first panel fits into the upper stile of the second panel, and the end wall provided on the upper stile of the second panel. Since it fits into the corner support, it is easy to position both.

Further, since the corner support provided on the first panel also serves as the support for the second panel, the number of support parts can be reduced. Further, since the upper stile of the second panel is supported by the corner support, the load applied to the second panel when the transport containers are stacked is received by the corner support via the upper stile and is not deformed.

Further, since the corner support is pressed onto the stile of the second panel and the second panel is held by the floor member by the grip metal fitting, the first panel does not come off from the floor member. No means for holding the first panel is required.

Further, when the corner metal fitting is attached, the engaging portions provided on the corner metal fitting are fitted into the slits provided on the upper stiles of the first panel and the second panel to prevent the positional deviation. The joining of the first panel and the second panel becomes more reliable. In addition, even if the loads of the upper transportation containers are concentrated on the support protrusions of the corner fittings when the shipping containers are stacked, the deformation prevention ribs provided on the upper wall of the corner fittings prevent the corner fittings from deforming, so the load collapses. Does not occur.

Further, since the engaging portion provided on the side wall of the corner fitting or the protruding portion provided on the locking portion engages with the upper stile to prevent coming off, the first panel and the second panel are inadvertently separated. The shipping container will not be disassembled.
