The building board 9 has a lower solid portion 92 formed in a stepped shape on an upper portion thereof. Then, in constructing the building board 9, the lower solid portion 92 of the building board 9 is covered,
The solid part 95 of the building board 9 is arranged.

As shown in FIG. 13, the upper end 920 of the lower solid portion 92 at the time of the above construction, transportation, manufacturing, or the like.
In addition, damage 921 such as chipping or cracking is likely to occur. After various studies on the cause, the ceramic building boards 9
Is, as shown in FIG. 14, an intermediate portion 90 in the thickness direction.
2 is lower than the density of the upper part 901 and the lower part 903 and is made in a rough state.
No. 2 was found to be susceptible to the above-described damage because its upper surface portion was formed exactly at the intermediate portion 902.

これを養生し，硬化させて作製する。That is, the ceramic building board 9 is made of, for example, cement, silicic acid-containing substance, hardening inorganic powder such as gypsum, reinforcing fibers such as wood chips, wood flour, pulp, wood fiber bundles, and water. Sprinkle the mixture on a template to form a plate,
This is cured and cured.

This is because the upper and lower surfaces of the building board are made to have high water resistance, high hardness, and high strength, while the middle portion 902 is made possible and has a low density to reduce the weight of the whole building board. Further, in the conventional building board 9, since the lower solid portion 92 is a right angle, the lower solid portion 92 is formed.
When arranging the upper solid portion 95 upward, the two easily collided, and actual damage, chipping, and the like were easily generated.

である。Further, the slope is formed so as to be lowered outward at the tip of the upper surface of the lower solid portion (FIG. 1). Preferably, the angle of the slope is 15 to 40 degrees with respect to the bottom of the building board. When the angle is less than 15 degrees, the effect of the present invention is hardly obtained. On the other hand, when the angle is more than 40 degrees, the strength of the lower solid portion may be reduced and the sealing property, which is a function of the lower solid portion, may be reduced. The building board is usually a quadrilateral as shown in FIG.

In the present invention, the slope is formed on the upper surface of the lower solid portion. Therefore, the tip of the lower solid part is not right-angled. Therefore, even if something comes into contact with the corner of the tip at the time of transportation, construction, or the like, damage such as chipping or cracking rarely occurs. During construction, the upper part of another building board is placed so as to cover the lower part of the building board, but since the tip of the lower part is sloped, the upper part is smooth.
Can be arranged in different locations. Therefore, no damage is caused to the tip of the lower solid part.

That is, in the ceramic building board, the reinforcing fibers such as the pulp and the wood fiber bundle are in a state in which the fiber directions are substantially aligned along the longitudinal direction of the building board (FIGS. 9 to 11). .
On the other hand, as shown in the first embodiment, a large-scale original building board produced at a factory as a general-purpose building board is used for a ceramic building board as shown in Embodiment 1 , and this is cut in the width direction (FIG. 6). It can be used as a small building board. This small building board is used as an adjustment building board when a building board is constructed or when a large building board is too large.

The cut surface is formed in a direction perpendicular to the longitudinal direction of the large original building board as described above (FIGS. 9 to 11). Therefore, the cut surface in the fiber direction of the reinforcing fiber is located on the cut surface. Therefore, the cut surface of the small building board is in a fragile state.

ることができるのである。When the above-described solid portion is processed into the cut portion, the tip of the solid portion is more brittle because the low density and the cut surface of the reinforcing fiber overlap. . Therefore, in the present invention, since the above-mentioned slope is formed in such a portion, damage to this portion can be prevented.
