  • Patent number: 8640412
    Abstract: In building a house, it is necessary to arrange bearing walls and non-bearing walls in a well-balanced manner. However, in the case where a bearing wall is configured by fixing a plate-like body such as a bearing wall panel to the exterior-side face of a structural frame member formed by assembling horizontal members and pillar members into the shape of a square frame, the surface of the bearing wall panel protrudes from the face of the structural frame member on the exterior side by a distance corresponding to the thickness of the bearing wall panel. Thus, the exterior-side face of the bearing wall in which the bearing wall panel is provided is not flush with the exterior-side face of the non-bearing wall in which the bearing wall panel is not provided, and so there is a step. Accordingly, processing of the base during attachment of an exterior building material has been necessary.

    Abstract: An unhardened inorganic board is shaped by press clamping the surface of an unhardened inorganic mat having a colored surface layer using an embossing template. A semi-hardened inorganic board is obtained by performing primary curing of the unhardened inorganic board, and coating the surface of the semi-hardened inorganic board with a primary sealer. The semi-hardened inorganic board coated with the primary sealer is autoclave cured to obtain a hardened inorganic board. The surface of the hardened inorganic board is coated with a powdery or granular material fixing sealer and, thereafter, an ornamental powdery or granular material is dispersed onto the surface of the hardened inorganic board. The surface of the hardened inorganic board on which the ornamental powdery or granular material has been dispersed is coated with a finishing transparent paint.
