Abstract

PURPOSE:To provide the product of an inorganic plate having even quality and to prevent generation of staining without generation of lye of lumber which is caused by effect of moisture by fixing lumber on the upper and lower faces of a plurality of pieces of cores arranged in the cross direction and sticking a rigid synthetic resin at least on the upper face. CONSTITUTION:A pallet 11 is constituted of a plurality of pieces of cores 12 arranged in the cross direction, a plurality of pieces of the upper and lower slender lumbers 13, 14 fixed by nails 17 with the prescribed intervals in the upper and lower parts of the cores 12 and rigid synthetic resin plates 15, 16 stuck on the upper and lower both faces. For example, a cement plate molding mixed with ligneous fiber is piled up on the pallet 11. Furthermore, the pallet 11 on which the cement plate molding has been piled is loaded in a plurality of steps and spontaneous curing of the cement plate molding is performed. Thereby, the upper and lower slender lumbers 13, 14 of the pallet 11 are protected and reinforced by the rigid synthetic resin plates 15, 16. Therefore, the pallet is prevented from being damaged and deflected in the case of piling up, transferring, loading and unloading of the cement plate molding.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pallet for curing inorganic boards such as fiber cement boards.

[0002]

2. Description of the Related Art Conventionally, in order to cure an inorganic plate molding, a plurality of core materials (2) are arranged in a lateral direction as shown in FIG. A pallet (1) with 4) was installed. As shown in FIG. 5, a plurality of inorganic plate molded products (5) are stacked on the pallet (1), and a plurality of inorganic plate molded products (5) are stacked on the pallet (1). The inorganic plate molded product (5) is loaded and naturally cured.

[0003]

However, in the above-mentioned conventional pallet (1), since the cured inorganic sheet moldings (5), which are heavy objects, are loaded and transferred or unloaded in the loaded state, The plate molded product (5) is easily bent by the weight and the pallet (1) is severely damaged. Further, in the above-mentioned conventional pallet (1), a gap S is formed between the elongated plate materials (3, 4), and the heat during the curing reaction of the molded inorganic plate (5) escapes through the gap S during curing. Therefore, the inorganic plate molded product (5) in the upper and lower parts shown in A of FIG. 5 has a slower curing reaction than the inorganic plate molded product (5) in the middle part shown in B, and the resulting inorganic plate product is There is a problem that the quality of performance varies. Furthermore, an elongated plate made of wood
In (3, 4), there is also a problem that an accretion due to the influence of water is generated during curing and a stain due to the accretion is attached to the product.

[0004]

[Means for Solving the Problems] As means for solving the above-mentioned conventional problems, plate materials (13, 14) are fixed to the upper and lower surfaces of a core material (12) arranged in a lateral direction, and at least the upper surface is fixed. The present invention provides a pallet (11) for curing inorganic plates, which is characterized in that hard synthetic resin plates (15, 16) are attached.

[0005]

In the pallet (11) of the present invention, since the hard synthetic resin plates (15, 16) are attached to at least the upper surface, the pallet (11)
The plate materials (13, 14) are protected and reinforced by the hard synthetic resin plates (15, 16). In addition, the pallet (11) does not have a gap through which heat can escape, and therefore the heat during the curing reaction during curing of the inorganic plate moldings (5) stacked on the pallet (11) is the hard synthetic resin plate (15, Pallet (11) by the heat insulation effect of 16)
It's hard to escape from.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to an embodiment shown in FIGS. 1 to 3. The pallet (11) comprises a plurality of core materials (12) arranged in a lateral direction and the core materials (12). Plural upper and lower elongated plate members (13, 1) fixed by nails (17) at predetermined intervals
4) and hard synthetic resin plates (15, 16) attached to both upper and lower sides
Consists of The hard synthetic resin plate (15, 16) is, for example, polymethacrylate, polystyrene, acrylonitrile-styrene-butadiene copolymer, diallyl phthalate resin,
A hard synthetic resin such as a phenol resin, a melamine resin, a polyester resin, a polyamide resin, an epoxy resin or a urethane resin, or a fiber reinforced plastic obtained by reinforcing the hard synthetic resin with a fiber such as glass fiber or carbon fiber (FR).
P) or the like is used as a material and is adhered to the upper and lower surfaces of the pallet (11) with an adhesive. As the hard synthetic resin plate (15, 16), it is also possible to use the waste material of the embossed type plate (FRP) used in the production of the inorganic plate.

On the pallet (11), as shown in FIG. 3, for example, cement board moldings (5) mixed with wood fibers are stacked. Then, the pallets (11) in which the cement board moldings (5) are stacked in this manner are further stacked in a plurality of stages, and the cement board moldings (5) are naturally cured. Since the upper and lower elongated plate members (13, 14) of the pallet (11) are protected and reinforced by the hard synthetic resin plates (15, 16), stacking, transfer and unloading of the cement plate molded product (5). Will not be damaged or flexed during And the upper and lower strips (13,1
Since the head of the nail (17) for fixing 4) to the core material (12) is also covered with the hard synthetic resin plate (15, 16), the nail head is fixed to the cement plate molding (5) during curing. Also, no dent is formed, and even if the nail (17) rusts, rust does not adhere to the cement plate molded product (5). The hard synthetic resin plate (15, 16)
This also prevents the nail (17) from falling off.

Table 1 shows the test results when the pallets of the present invention (the present invention) and the conventional pallets (comparative examples) were used for the natural curing of cement boards mixed with wood fibers.

[Table 1]

According to Table 1, the variation in temperature during curing of the upper, middle and lower parts of the cement plate naturally cured by using the pallet of the present invention is smaller than that when the conventional pallet is used. As a result, it is shown that the quality variation of the obtained products is smaller than that of the conventional products.

Except for the above-mentioned embodiment, the upper and lower elongated plate materials (13, 1
4) may be closely arranged without forming a gap, or may be stretched with a single plate material on the entire upper and lower surfaces.

[0011]

Therefore, the pallet of the present invention has durability, and when the pallet of the present invention is used to cure an inorganic plate, an inorganic plate product having less variation in quality can be obtained. In addition, since a hard synthetic resin plate is attached, the plate material will not be scratched due to the influence of moisture, so that the inorganic plate product will not stain.
