Is formed by binding a set number of roof tiles 1 with a PP band 2 as shown in FIG.

At this time, in order to prevent breakage of the roof tile 1, a cushioning material 3 is laid on the pallet 4 and the lower juxtaposed body 1B. It is stacked on the pallet 4 so as to be vertical.

The seat 5 is made of a waterproof air cushion sheet or a polyvinyl chloride sheet, and the net 6 is made of an elastic stretch net.

As a result, cracks and the like of the roof tile 1 can be reliably prevented from being generated during transportation or storage, and the steam generated from the roof tile 1 can be released through the gap of the net 6, so that the inside of the package 1D , The occurrence of dew condensation can be prevented.

However, in the package 1D, it is not possible to reliably prevent infiltration of rainwater or the like.
When stored indoors or outdoors, it is preferable to cover with a waterproof cover.

Specifically, 640 mm long × 420 mm wide
X Four tiles 1 each having a thickness of 10 mm and a weight of 4.7 kg are stacked and tied together with a PP band 2 using a tying machine (not shown) to form a tying body 1A, and then 14 tying bodies 1A are arranged in parallel.
Similarly, the juxtaposed body 1B is formed by binding with the PP band 2a.

On the other hand, as shown in FIG. 4, four girder members 41 arranged at set intervals, and five girder members fixed to the upper and lower surfaces of these girder members 41 at set intervals, respectively.
On the upper surface of the pallet 4 having a length of 1040 mm, a width of 690 mm and a height of 87 mm formed by the two plate members 42 and the three plate members 43, a length of 1000

The juxtaposed body 1 is placed thereon by a handling device (not shown).
B, the cushioning material 3 is again placed on the upper surface of the juxtaposed body 1B.
(See FIG. 5). Next, by stacking the juxtaposed bodies 1B on the upper surface of the cushioning material 3 again, the stacked body 1C including the juxtaposed juxtaposed bodies 1B and 1B is formed (see FIG. 6). When the stack 1C is formed, the air cushion sheet 5 having a length of 1400 mm × 1200 mm × 4 mm is placed on the upper surface of the stack 1C.
Of the upper surface and the upper end of the four surrounding sides (approximately 20
(See FIG. 7), and a 500 mm wide elastic stretch net 6 having a triangular mesh of about 20 mm on a side is stacked by a film packaging machine (not shown) on the stack 1B including the pallet 4 Around the four sides from above to below. The upper end of the winding of the stretch net 6 is a stack 1C.
Until it reaches a position about 100 mm inward from the corner of the upper surface of. Thus, the package 1D shown in FIG. 1 is formed.

For comparison with the above-described embodiment,
Comparative Example 1X shown in FIG. 8 was formed. This comparative example 1X is
After forming the same stack 1C as the above-described stack 1C, placing the same air cushion sheet 5 on the upper surface of the stack 1C, and covering the upper surface of the stack 1C and the upper end of the four peripheral sides, Instead of the stretch net 6, a stretch film (300% stretch type) 7 is wound around four sides of the stacked body 1C including the pallet 4 and the periphery of the upper surface in order to cover.

Here, with respect to the embodiment and the comparative example, the temperature difference and humidity inside the package at the time of outdoor storage, the presence or absence of dew condensation inside the package, and the presence or absence of efflorescence at the time of outdoor storage were measured and observed. . Table 1 shows the results.

[0019]

[Table 1]

According to the measurement results, in the package 1D of the embodiment, generation of surface dirt on the roof tile 1 due to efflorescence was not observed for three months in outdoor storage, but in the package 1X of the comparative example. One month after the outdoor storage, the roof tile 1 was stained by efflorescence.

In the above-described embodiment, a tile is described as a cement-based plate material. However, the present invention is not limited to a tile, and may be applied to packing of other cement-based plate materials, for example, building materials such as wall materials. Can be.

In addition, the case where the roof tiles 1 are stacked via the cushioning material 3 made of styrofoam has been exemplified. However, when a cement-based plate material such as a tile whose end face is painted is directly loaded on the cushioning material 3 made of styrofoam, There is a risk that the part will come off. In such a case, a cushioning material 3 prepared by laminating a polypropylene film on at least one surface of a polystyrene foam is prepared, and a cement-based plate material is loaded so that the painted surface is in contact with the polypropylene film laminated surface, or the cushioning material 3 is provided. Laying can prevent the paint from peeling off.
