も生じない。That is, according to the present invention, the composite inorganic plate is integrally formed by a single molding die instead of forming each single plate in advance as in the conventional case and then integrally forming each single plate. Therefore, unlike the conventional case, the complicated steps of performing casting and integral molding in separate steps are not required, the molding process can be simplified, and molding can be performed in a space-saving manner and at low cost. realizable. The composite inorganic plate thus obtained is formed by press-fitting the core layer with a material different from that of the outer peripheral layer from the bottom opening, and is formed in a state of extending in the outer peripheral direction around the bottom opening. . For this reason, the core layer and the outer peripheral layer made of different materials are in a continuous state at the interface, and the bonding strength between them is extremely large, and the core layer is wrapped in the outer layer and does not come into contact with the outside air. There is no problem of peeling and corrosion.

Then, in order to obtain a composite inorganic plate having high strength, glass fiber mixed concrete having high tensile strength is used as a core layer forming material. Further, it is possible to reduce the weight by using foamed concrete as the core layer forming material. Furthermore, if a low-cost material is used, a more effective product cost reduction can be achieved.

る。The composite inorganic plate of the present invention is produced using the above-mentioned casting mold, for example, as follows. That is, three kinds of slurry A material, B material and C material are prepared in advance. And
As shown in FIG. 2, the B material 16 is filled into the recess in the lower mold 11 so as to form two layers, and then the A material 17 is sequentially filled. At this time, the total amount of filling is 60 to 85 of the inner volume of the lower mold 11.
It is necessary to make it%. That is, when the filling amount is less than the above range, the inflow amount of the C material at the time of casting increases, so that the influence of the flow on the A material 17 and the B material 16 becomes large and the shape easily deforms. On the contrary, if the filling amount is larger than the above range, the inflow amount of the C material 18 at the time of casting becomes small and the molding becomes insufficient. After filling the lower mold 11 with the two types of base sludge 16 and 17 in this manner, the upper mold 10 is lowered and the mold is clamped. As shown in FIG.
Material 18 is cast, and A material 17 and B material are applied to the inner surfaces of the upper mold 10 and the lower mold 11.
Absorbs the moisture of 16 and C material 18 and A material 17, B material 16 in the mold
And the C material 18 is integrally molded. At this time, the C material 18
As shown in FIG. 4, it infiltrates between the A material 17 and the B material 16, and lifts up the A material 17 while spreading to the left and right in the mold. Next, this is demolded, and as shown in FIG. 5, A portion 17 'derived from A material 17 and B derived from B material 16 are obtained.
A composite inorganic shaped body is obtained in which the C portion (core layer) 18 'derived from the C material 18 is flattened around the bottom opening between the portions 16'. Therefore, when this shaped body is cured, it is possible to obtain a composite inorganic plate in which three different kinds of materials are overlapped with each other.
