PURPOSE: A door is provided to simplify assembling processes of a reinforcing member and prevent torsion by the wood characteristic and the stiffness on outer impact. CONSTITUTION: A door(100) comprises followings. A reinforcement plate(120) is made of aluminium materials. A reinforcement plate has a square plate shape. An assembly projection(122) is protruded at the constant height toward one direction or bidirection of the reinforcement plate. A side plate(110) is made of lumber. The side plate is coupled on one side or both sides of the reinforcement plate. The side plate has a sheet shape having the same area as the reinforcement plate. An assembling groove(112) is formed at the side plate. An frame drawing hole is formed in the forming direction of the assembling projection. The cross-sectional shape of the assembling projection is protruded in a T-shape. The cross-sectional shape of the assembling groove is depressed in a T-shape corresponding to the assembling projection. |
