The space unit is formed in the upper board and the lower board. The reinforcing member is inserted into the space unit. The upper board includes an upper plate(112) and a first bending unit(114). The lower board includes a lower plate(122) and a second bending unit(124). The side unit of the board is formed to be two-ply. |
