<p><P>PROBLEM TO BE SOLVED: To provide a wall structure and a construction method of the wall structure that can considerably suppress crack initiation. <P>SOLUTION: The wall structure includes a wall backing board 2; an undercoat layer 3 formed by coating the surface of a gypsum board 2 with an undercoating material; a net-like sheet 4 embedded in the undercoat layer 3; and a finishing material layer 5 formed by coating the surface of the undercoat layer 3 with a finishing material. The undercoat layer 3 has a thickness of 3 mm or more, and the net-like sheet 4 is embedded inside from the surface on the surface side of the undercoat layer 3. Since the net-like sheet 4 is embedded in the undercoat layer 3, the strength of the undercoat layer 3 itself is increased to enhance a resistance force to the causes of crack initiation. Further, since the net-like sheet 4 is embedded on the surface side of the undercoat layer 3 with the thickness of 3 mm or more and located away from a joint of the gypsum board 2 which is a place of causing cracks, even if a crack is initiated near the joint of the gypsum board 2, it hardly reaches the surface side of the undercoat layer 3, obtaining a wall surface of fine appearance causing no cracks. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
