<P>PROBLEM TO BE SOLVED: To effectively prevent dew condensation on a surface on the indoor side while attaining an extremely simple structure. <P>SOLUTION: For a door frame and its attachment structure, a door frame 1 comprising a metal plate, to which a door 20 is openably and closably connected to the inner side through a hinge 22, is fixed to a building. The door frame 1 includes a vertical frame 2A on a doorstop side, a vertical frame 2B on a hinge side, and an upper frame 3 formed by connecting the upper ends of both jambs 2. The vertical frame 2A on the doorstop side, the vertical frame 2B on the hinge side and the upper frame 3 are provided with a bent projection part 5 formed by being projected to the surface on the outdoor side and bending the metal plate in a folded state to be in two layers, and further a plane part 6 in parallel with the external wall surface of the building is provided on the outer side of the bent projection part 5. In the attachment structure of the door frame, the door frame 1 is fixed to a skeleton 30 of the building, a heat insulating gap 13 is provided between the bent projection part 5 and an external wall in a plane part 6 of the door frame 1, an external wall panel 31 is fixed to the skeleton 30 of the building, and the heat insulating gap 13 between the external wall panel 31 and the bent projection part 5 is caulked. <P>COPYRIGHT: (C)2012,JPO&INPIT |
