- a flat board having a front surface and a back surface opposite to said front surface;
- a reinforcing frame body secured to said back surface of said flat board and having a surface facing in the same direction as said back surface of said flat board;
- at least one flange disposed on said surface of said reinforcing frame body, said flange including a semi-circular frame body and a hooking part including a projection extending along a peripheral edge of said semi-circular frame body.
A form panel assembly comprising:
- a fiat board having a front surface and a back surface opposite to said front surface;
- a reinforcing frame body secured to said back surface of said flat board and having a surface facing in the same direction as said back surface of said flat board;
- at least one flange connected to said surface of said reinforcing frame body, said flange being a semi-circular flange body having an L-shaped cross section, said semi-circular flange body having a hook projection extending along a peripheral edge of said semi-circular flange body, said hook projection defining an engaging surface;
