Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a loading structure of the building board consisting of a fiber維補strong cement board.

[0002]

BACKGROUND OF THE INVENTION Fibers維補strong cement plate roofing, are used in the building board of the outer wall material such as, in the production of the fiber reinforced cement board, wood fiber, and a reinforcing fiber and cement such as synthetic fibers A dry method or a semi-dry method in which the main raw material mixture is sprinkled on a template and cured by heating under pressure in the presence of water, a dry method or a semi-dry method, the raw material mixture is made into a slurry to be dehydrated, and a predetermined sheet of the obtained sheet is laminated. It is manufactured by a wet method of curing the laminate by heating under pressure, a casting method of injecting the slurry into a molding frame for paper-making dehydration, and then curing for curing.In any method, the product is immediately after production. They are loaded onto pallets and transported or stored.

2. Description of the Related Art Conventionally, building boards such as the fiber-reinforced cement boards are simply stacked on a pallet in a predetermined number and bound in a tape form (for example, Japanese Utility Model Publication No. 63-23287).

[0004]

As described above, the fiber reinforced cement board is heated by the compression heating curing step or the coating step, which is the final step during loading, regardless of whether it is a dry method, a wet method, or the like. Although it radiates heat during loading and is naturally cooled, in the conventional method of simply stacking as described above, the degree of heat radiation, that is, the degree of natural cooling, differs at the upper, middle and lower parts of the load, and therefore the fibers The degree of curing and hardening of the reinforced cement board, the degree of drying or hardening of the coating film on the surface, and the degree of deformation of the fiber reinforced cement board itself due to temperature changes are different in the upper part, middle part and lower part, and the product quality varies. May occur.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described with reference to a specific example shown in FIGS. 1 to 5. The building board (1) shown in FIG. 1 is made of fiber reinforced cement board and is used as a flat roofing material. , Has a substantially base plate shape consisting of a rectangular main body part (1A) and a root end part (1B) whose width decreases toward the root end and both sides are concave curves, and the length of the tip edge is Let a be the length, b be the length of the root edge, and c be the length of the side edge, and a> b and c>
b, the length d between the tip edge and the root edge is set to a / 3 or slightly smaller, and the thickness is usually 5 to 7 mm.
Is set to. The conditions relating to a, b, c, and d above relate to this specific example, and do not limit the present invention. The building board (1) is coated on the surface after heating and curing, and after the coating film is dried by heating, usually 5 to 15 sheets (for example, 10 sheets) are laminated in the same direction as shown in FIG. The band (2) is united to form a unit (3). The band (2) may be tape-shaped or string-shaped.

As shown in FIG. 3, the units (3) are arranged in a set of three in a line in the longitudinal direction, and the outer one is rotated 180 ° with respect to the other two and the root end is inward. As it is, it is placed on the pallet (4). In this case, the vertical and horizontal widths D of the array of the three units (3) are set to be substantially equal. After placing the set of units (3) on the first stage on the pallet (4) in this way, the set of units (3) on the second stage arranged in the same manner as the first stage is placed on it. At this time, as shown in FIG. 4, the unit (3) of the first stage is placed with its phase shifted by about 90 ° with respect to the set.

In this way, as shown in FIG. 5, a set of units (3) having a plurality of stages (usually 10 to 15 stages) is approximately 90
When rotated and placed with the phases shifted, the gaps between the building boards (1) in the set of units (3) at each stage are crossed and stacked, as shown by the diagonal lines in Fig. 4. Four vertical air circulation holes P are formed in the load (5). Therefore, in the building board (1) of the unit (3) at each stage of the load (5), the residual heat of the heating and drying process after painting remains in the loaded state immediately after manufacturing, but the residual heat is Not only the peripheral wall of 5) but also the air circulation hole P diffuses to the outside, so that each building board (1) of the load (5) is cooled substantially uniformly.

The present invention is not limited to the above specific examples, and two or three or more units (3) of a building board (1) may be combined in a predetermined stage, for example, four units (3 6) is combined, the result is as shown in FIG. Further, the building board (1) may have any shape as long as it has a substantially base board shape and the gaps between the units in each stage are overlapped to form an air circulation hole. For example, the root end portion shown in FIG.
(31B) is a building board having a shape consisting of a convex curve on both sides and a concave curve continuing to it (31) or a building board with the above-mentioned shape having rounded corners is a substantially base board-shaped building board include.

EFFECT OF THE INVENTION In the present invention, the compression heating curing step or
Loading-shaped building board in a heated painting process depending on the heat storage state
Since the heat is dissipated in a substantially uniform manner, the degree of curing and hardening of each building board, the degree of drying or hardening of the coating film, and the deformation of the building board due to heat dissipation are also uniform, resulting in variations in product quality. Is less.
