PURPOSE: To connect a wall panel at a specified angle by laying out a plurality of connection parts which are connected to each connected part of the upper end of each wall panel so that each wall panel may be placed in a cross-shaped butt angle state and formed with a plate in one piece.
CONSTITUTION: Connection parts 18C, 18D, 18E and 18F, which are connected to each of connected parts 20C, 20D, 20E and 20F on the upper end of each of wall panels 7C, 7D, 7E and 7F are mutually laid out side by side, and the connection parts 18C and 18E and the connection parts 18E and 18F are laid out on the same straight line, thereby forming a rectangular shape in one piece. The length L which runs along the longitudinal sides of the wall panels 7C to 7F which are equivalent to each of the connection parts 18C to 18F is set so that it may be more than two times the thickness T of the corresponding wall panels 7C to F, thereby forming a connector 18.
