きた。2. Description of the Related Art A gypsum board is a board formed by coating a gypsum material prepared by mixing calcined gypsum with sawdust and kneading it with water, coating both sides with cardboard, and drying. It is excellent in fireproofing and soundproofing, has little expansion and contraction due to temperature and humidity, but has the property of being weak against shock and moisture. Conventionally, regarding a structure in which a notch groove is provided on a plaster board and the corner is formed by bending the notch groove as a center, a “partition panel” shown in Japanese Utility Model Publication No. 55-43849 or Japanese Patent Publication No. 1-12902 is disclosed. In the "corner panel" shown, a technique has been disclosed in which a so-called "V cut" is applied to a gypsum board to form a cutout groove, and the cutout groove is bent to form a corner portion. .
