PURPOSE: A reinforcing structure for a door frame is provided to simply manufacture synthetic resin frames having various sizes without the use of a new mold. CONSTITUTION: A reinforcing structure for a door frame comprises a panel(31), a sheet(32), a bent portion(35), a metal reinforcement(37), and a resin adhesive layer. The sheet is attached to the panel to form a surface layer. The panel having the sheet can be bent along the bent portion. The metal reinforcement is attached to the inner wall of the panel to reinforce the strength of the panel. The gap between the metal reinforcement and the inner wall of the panel is filled with the resin adhesive layer, and the resin adhesive layer supports the metal reinforcement. |
