Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pallet girder made of cardboard.

[0002]

2. Description of the Related Art As a pallet that does not require insect repellent treatment, a pallet made of cardboard as shown in FIG. 7 has been used. In this pallet, a top plate 50 and a bottom plate 51 are fixed via a plurality of girder members 52, and a fork insertion port 53 of a forklift is formed between adjacent girder members 52, 52.

As shown in FIG. 8, the girder member 52 has a structure in which an end face of a laminated body 55 composed of a number of corrugated cardboard sheets 54 is covered with an end face plate 56.

[0004]

However, such a girder member as described above is heavy, which causes a load during transportation, and also requires a large amount of corrugated cardboard sheets during production, and thus it takes a lot of time to form a laminate. Was.

Therefore, the present invention is lightweight and excellent in strength,
An object of the present invention is to provide a girder member of a cardboard pallet which can be easily manufactured with a small amount of material.

[0006]

In order to solve the above-mentioned problems, the present invention provides an outer standing plate, a facing plate, an inner standing plate, and a supporting plate which are successively provided on both side edges of a main plate, and a leading end of the supporting plate is provided. The outer standing plate and the facing plate are brought into contact with each other, the inner standing plate is abutted to form a cylinder, and a wedge member is inserted into the cylinder via a cutout formed in the main plate. The wedge member is engaged with a notch formed in a continuous portion between the inner plate and the support plate, and the adjacent inner plate is sandwiched by the notch formed at the tip of the wedge member. .

In this girder member, the cylindrical body is retained by the wedge member, and the outer standing plate and the inner standing plate are reinforced by the support plate to maintain a space between the main plate and the facing plate. Sufficient strength can be obtained without using.

[0008]

FIG. 1 (a) shows a development substrate of a tubular body T of a girder member according to the present invention. The development board is made of a corrugated cardboard sheet in which the step direction is in the width direction. On both side edges of the main plate 1, an outer standing plate 2, a facing plate 3, an inner standing plate 4, and a supporting plate 5 are sequentially provided in order.

A notch 6 is formed in the main plate 1, and a notch 7 is formed in a continuous portion of the standing plate 4 and the support plate 5 in the width direction of the development board.

FIG. 1B shows a development substrate of a wedge member W used for shape preservation of the cylindrical body T. This development board is formed by a pair of wedge pieces 8, 8 connected to each other, and a cut 9 is formed at the tip of each wedge piece 8. This development board is also made of a corrugated cardboard sheet, and the direction of the step is parallel to the cut portion 9.

Now, in order to assemble the developed substrate shown in FIG. 1A to form the cylindrical body T, as shown in FIG. 2, the outer plate 2, the facing plate 3, and the inner plate 4 Then, the supporting plate 5 is sequentially bent in the same direction, and the tip of the supporting plate 5 is brought into contact with the continuous portion of the outer standing plate 2 and the facing plate 3, and the inner standing plates 4, 4 are abutted. When the cylindrical body T is assembled in this manner, the step direction of the outer standing plate 2 and the inner standing plate 4 becomes the vertical direction.

A wedge member W is formed by superimposing the wedge pieces 8, 8, and the wedge member W is inserted into the cylindrical body T through the notch 6, and the wedge pieces 8, 8 are inserted into the notch 7. And the notches 9 as shown in FIG.
, The shape of the cylindrical body T is maintained.

In order to form a pallet using the above-mentioned beam members, a top plate 10 and a bottom plate 11 are adhered to the main plate 1 and the facing plate 3, respectively, as shown in FIGS. Are integrated. At this time, the top and bottom of the girder member may be reversed. Here, the pallet of FIG. 5 is provided with fork insertion ports 12 on two sides, and the pallet of FIG. 6 is provided with fork insertion ports 12 on four sides.

In the above-mentioned pallet, even if a compressive force acts between the top plate 10 and the bottom plate 1, the outer plate 2 and the outer plate 2 with the bending direction excellent in bending strength directed in the vertical direction as the direction in which the load acts. Since the inner standing plate 3 is reinforced by the supporting plate 5 and maintains the space between the main plate 1 of the beam member and the facing plate 3, deformation can be prevented without using a large amount of corrugated cardboard sheets.

[0015]

As described above, in the girder member according to the present invention, the cylindrical body is retained by the wedge member, and the outer and inner standing plates are reinforced by the support plate, so that the main plate and the facing plate are reinforced. In order to maintain the interval, sufficient strength can be obtained without using a large amount of corrugated cardboard sheets.

Further, since there is no need to form a laminate of corrugated cardboard sheets, it can be easily manufactured.
