Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel loading structure in which various panels such as a wall panel are loaded on a pallet.

[0002]

2. Description of the Related Art Various types of panels, such as wall panels in houses, are generally produced in factories, and these panels are transported or stored at a production site, transported at the time of shipment, or transported or stored at a construction site. The appropriate number of panels are stacked on a pallet.

[0003] When panels of different lengths coexist, a plurality of panels stacked on a pallet have a space between the panels or between the pallets and the panels due to the difference in length. When such a space is created, when an operator walks on a pallet loaded with panels and applies a load, the panels located in the space will be deformed and defective products will be generated. Worker trips.

Conventionally, in order to solve this problem, a method of inserting a cushioning material made of expanded polystyrene into a space between panels or a space between pallets and panels caused by a difference in panel length has been adopted.

In this case, the expanded polystyrene block must be cut so that the height of the expanded polystyrene block is substantially the same as the height of the space. However, the expanded polystyrene block cannot be easily cut with a knife or the like. However, it is not easy to deal with this by cutting it on site.

[0006] Therefore, there is prepared one which has been cut into several kinds of heights in advance, and a foamed polystyrene block having the best height is selected from the cut pieces and used.
It is rare that there is something that is almost as high as the height of the space. To use the same height as the space, a large number of expanded polystyrene blocks having different heights must be prepared, which is too expensive and impractical.

For this reason, a foam polystyrene block having a slightly lower height is selected from several kinds of heights prepared in advance, and this block is inserted into a space, and the lower surface of the block is attached to a panel so that the block does not come off or slip out of the space. In addition, the pallet is used by bonding it with an adhesive. In addition,
If you use blocks that are too tall than the height of the space,
The panel is constantly used in the opposite direction, and the panel may be warped and not used.

[0008]

However, there is a problem that the work of bonding the expanded polystyrene block to the panel or pallet with an adhesive is troublesome and time-consuming. Further, after transporting the panel to the construction site, the unneeded expanded polystyrene block cannot be disposed of on site, and must be disposed of as industrial waste in a specific facility, which is also problematic.

The present invention solves the above problems,
The purpose is to easily adjust the height at the panel production site even if the height of the space between the panels or between the pallet and the panel varies due to the difference in panel length. Another object of the present invention is to provide a panel loading structure that can be easily disposed of at a panel construction site.

[0010]

In order to achieve the above object, according to the present invention, a plurality of panels in which panels of different lengths are mixed are stacked on a pallet, and an end portion caused by the difference in length is provided. In the space between the panels or between the pallets and the panels, a cushioning material made of corrugated paper or honeycomb structure paper formed by bending a corrugated cardboard is sandwiched with its structural cross section facing the panel surface or the pallet surface. A panel loading structure is provided.

Hereinafter, the panel stacking structure of the present invention will be described in detail with reference to the drawings. FIG. 1 is a side view showing an example of a panel stacking structure of the present invention, and FIGS. 2A to 2D are perspective views showing examples of a cushioning material used in the present invention.

In FIG. 1, reference numeral 10 denotes a normal pallet, which is generally made of wood or plastic. On this pallet 10, a plurality of (six in the figure) panels 20a and 20b in which panels of different lengths are mixed.
... are stacked. Panels 20a, 20b
························ 各種 パ ネ ル 外 な ど な ど 外 外 外 外 住宅 住宅 住宅 外 住宅 住宅.

Here, of the plurality of panels stacked on the pallet 10, the uppermost panel 20a and the lowermost panel 20b are different in length and longer than the other panels. This difference in length creates a space 30 between the end 21a of the uppermost panel 20a and the end 21b of the lowermost panel 20b.

The space 30 does not always occur between the uppermost panel 20a and the lowermost panel 20b. For example, if a halfway panel is long, the space 30 is generated in that part. Also, for example, the uppermost panel 20a
If only the top panel 20 is
A space 30 will be created between the end 21a of FIG.

In such a space 30, a cushioning material 40 made of cardboard-structured paper or honeycomb-structured paper formed by folding a cardboard is sandwiched. As shown in FIGS. 2A, 2B, and 3C, the cushioning material 40 is a cardboard structure paper formed by folding a corrugated cardboard into a triangular shape, a square shape, or a spiral shape, or as shown in FIG. As shown in d), hexagonal honeycomb structured paper is preferably used.

As shown in FIG. 2, these cushioning members 40 are sandwiched in the space 30 with the structural section facing the panel surface or the pallet surface. The reason that the structure section is sandwiched in such a manner that the structure section is directed to the panel surface or the pallet surface, that is, in the vertical and vertical directions, is to increase the compressive strength of the cushioning material 40 and to withstand the vertical and vertical loads. is there.

In this case, the height of the cushioning material 40 is
Is preferably set to be about 2 to 5 mm higher than the height. If it is set lower than 2 mm, the height of the cushioning material is reduced when a load is applied, so the cushioning material may be displaced. Conversely, if it is set higher than 5 mm, the upper panel end may be warped. is there.

The cushioning material 40 is firmly clamped simply by pushing its structural cross section toward the panel surface or the pallet surface into the space 30, but when the panels are stacked on the pallet, the panel surface or the pallet surface is Place cushioning material 40 on
You may pinch it so that another panel on it may be piled up. Thus, the stacking structure of the panel of the present invention is obtained.

[0019]

In the panel stacking structure of the present invention, the cushioning material is made of cardboard-structured paper or honeycomb-structured paper formed by folding a cardboard, and the structure cross section is sandwiched in the space toward the panel surface or the pallet surface. As a result, the compressive strength is relatively high and can withstand loads.

Moreover, such a paper cushioning material can be easily cut to a desired size using a ruler and a cutter knife or a simple push-off tool at a panel production site. Since it is possible, a cushioning material suitable for the height of the space can be prepared. . Further, when the panel becomes unnecessary at the construction site of the panel, it can be easily disposed of.

[0021]

Next, an embodiment of the present invention will be described.
The present invention is not limited to these examples.

(Embodiment) As shown in FIG. 1, on a wooden pallet 10, one wall panel 20b having a length of 2160 mm × a width of 800 mm × a thickness of 13 mm is placed.
Five wall panels each having a size of 800 mm x a width of 800 mm x a thickness of 13 mm were stacked, and a wall panel 20a having a length of 2160 mm x a width of 800 mm x a thickness of 13 mm was placed thereon.
This wall panel is for a bathroom, and is formed by bonding a PVC-coated steel plate to one side of a gypsum board.

In this case, since the three side surfaces of the seven wall panels 20a, 20b,..., Which are stacked in total, are flush with each other, the remaining side surfaces have the lengths of these wall panels. Due to the difference, the end 21a (36
0 mm portion) and the end 21b (3
A space 30 having a height of 65 mm is formed between the space 30 and the 60 mm portion.

As the cushioning material 40, the following three types of corrugated paper were used. Height 68mm x Length 3
Corrugated cardboard structure paper formed by double-folding a 00 mm x 5 mm thick cardboard into a triangular shape (68 mm high x 5 sides)
0mm), height 68mm x length 400mm x thickness 5m
cardboard structure paper (68 mm high x 50 mm on a side) formed by double-folding a square m cardboard into a square shape, height 6
Corrugated cardboard paper (height 68 mm) formed by spirally bending corrugated cardboard of 8 mm x 500 mm x 5 mm thick
X outermost diameter 100 mm). In addition, the edge part of each said corrugated cardboard structure paper is stopped with adhesive tape.

The cushioning material 40 made of the above three types of corrugated cardboard paper is used, and each cushioning material 40 has a structural cross section of the end 21a of the panel 20a and the panel 2a.
Ob was sandwiched in the space 30 so as to face the end 21b surface of Ob to obtain a stacked structure of three types of panels. It should be noted that two types of the same type of cushioning material 40 are used for the loading structure of one type of panel, and these two cushioning materials 40 are located 200 mm inward of the space 30 from the width side of the panel and the panel At a position 150 mm inward of the space 30 from the side surface of the end.

With respect to the thus obtained stacking structure of the three types of panels, 60 kg is placed on the end 21a of the uppermost panel 20a corresponding to substantially the center between the two cushioning members 40.
After the passage of time, the load was removed, and the deformation of the end 21a of the wall panel 20a and the cushioning material 40 was observed.

As a result, in the case where the cardboard structure paper was used as the cushioning material 40, no deformation was recognized at the end 21a of the wall panel 20a in any of the stacking structures of the panels. In the case of using the corrugated cardboard structured paper, no deformation was recognized in the cushioning material 40. In the case of using the triangular corrugated cardboard structure paper and the case of using the quadrangular corrugated cardboard structure paper, slight deformation was observed in the cushioning material 40, but there was no problem such as detachment or displacement of the cushioning material 40 in practical use. Was.

[0028]

As described above, in the panel stacking structure of the present invention, the cushioning material is made of corrugated cardboard structural paper or honeycomb structural paper formed by bending corrugated cardboard, and the structural section is directed to the panel surface or pallet surface. Since it is sandwiched in a space, its compressive strength is relatively strong, it can withstand loads well, and even if a worker walks on a pallet loaded with panels and a considerable load is applied, deformation of panel products will not occur. Can be prevented.

Moreover, such a paper cushioning material can be easily cut to a desired size using a ruler and a cutter knife or a simple push-off tool at a panel production site. Therefore, even if the height of the space between the panels or the space between the pallet and the panel caused by the difference in the length of the panel varies, the height can be easily adjusted to the optimum height at the panel production site.

Therefore, the cushioning material can be satisfactorily sandwiched in the space between the panels or between the pallets and the panels without fixing the cushioning material using an adhesive, thereby preventing the cushioning material from shifting or coming off. Can be saved.

Another advantage is that when the cushioning material is no longer needed at the panel construction site, it can be easily disposed of. In addition, recycling is also possible.
