PURPOSE:To mold sharply even the joint part in a complicated form efficiently and damagelessly without requiring post-processing, by a method wherein cement slurry is cast into a joint part-molding part of a molding tool after arrangement of a molten row foamed material in a fixed form into the joint part-molding part of the molding tool, the real part is molded by performing autoclave-curing after demolding. CONSTITUTION:A surface molding tool 2 is arranged within a concrete shuttering molding tool 1 and a meltable foamed material 3 is arranged within a joint part molding part. Then cement slurry 4 as a mineral panel molding material is cast into the concrete shuttering. The cast cement slurry 4 is demolded from the concrete shuttering molding tool 1 after cure with precure. With this construction, a mineral cured plate 5 having the foamed material 3 is obtained. Then the demolded mineral cured plate 5 is autoclave-cured. The foamed material 3 is molten and the joint part 6 is formed, in this curing. |
