Abstract

PURPOSE: To manufacturing a building plate, easily, by foaming a foamable composition in a mold containing a sheet, thereby closely contacting the sheet to the mold by the foaming pressure and integrating with the foaming composition.
CONSTITUTION: For example, a sheet 8 such a soft PVC resin sheet is placed in a lower mold 7 having a concave cavity 6. A foamable urethane liquid 11 is poured on the sheet 8, the cativy 6 is closed with an upper mold 12, and the urethane is expanded. The sheet 8 is softened and pressed closely to the surface of the mold 7 by the pressure and heat of expamsion, to obtain the objective building plate composed of the urethane foam laminated with the sheet.
