Claims

[Scope of Claim for Utility Model Registration] A bent plate material formed by bending at least one end of a plate-shaped body 1 into a curved shape and folding it back to overlap the non-bent part, in which both the front and back sides of the plate-shaped body 1 are larger than the middle layer part. A medium-density fiberboard with a high specific gravity is used, and a notch of approximately half the thickness of the board is formed in the width direction of the bent part of the board, reaching the tip edge of the board to form the convex piece 2. A concave notch 3 of an arbitrary depth is formed so as to leave more of the surface layer X on the back side of the convex piece 2 to be bent, and the back side z of the convex piece at the tip of the convex notch 3 is formed as a convex rearward from the concave notch 3. In addition, a substantially semicircular space 4 is formed by the concave notch 3 so as to overlap the back surface y of the piece.
A bent plate material characterized in that it is bent and fixed in a curved manner so as to form a shape, and the space 4 is filled with a reinforcing material.
