  Next, the drainage route will be described. As shown by the arrows in FIGS. 2 and 3, when water enters the space communicating with the opening 21 and the opening 31, the door-side surface of the first heat insulating material 61 and the suspension-side of the door-core material 44. Trying to flow down between the two surfaces. Similarly, when water enters the space communicating with the opening 22 and the opening 32, the space communicating with the opening 23 and the opening 33, and the space communicating with the opening 24 and the opening 34, the first heat insulating material is used. Water tends to flow through the gap between 61 and the door core material 44. In each space, all are separated from the paper core 50 by the first heat insulating material 61, the second heat insulating material 62, and the third heat insulating material 63, so that water flows downward without contacting the paper core 50.

  FIG. 4 is an enlarged view schematically showing the positional relationship between the first heat insulating material 61 and the lower heat insulating material 64 of the present embodiment. As shown in FIG. 4, a lower heat insulating material 64 is disposed on the lower surface of the first heat insulating material 61 and separates the door core material 44 and the paper core 50. The lower heat insulating material 64 of the present embodiment is disposed without interruption between the first heat insulating material 61 and the lower core material 42, and reliably regulates the flow of water from the door core material 44 to the paper core 50. It is supposed to be. Therefore, as shown by the arrow in FIG. 4, even when water has reached the lower surface of the first heat insulating material 61 through the gap with the door core material 44, the paper core 50 is wetted by the lower heat insulating material 64. The situation is surely prevented. In the present embodiment, since the lower heat insulating material 64 is in contact with the upper end of the lower core member 42, the lower heat insulating material 64 reaches the lower end portion of the door body 10 without touching the paper core 50.

According to the embodiment described above, the following effects can be obtained.
The door body 10 includes a door core material 44 disposed on the door edge side of the door body 10, and a leader 91, an upper cylinder lock 92, a handle 93, and a lower cylinder lock 94 on the suspension side of the door edge core material 44. The outdoor surface material 20 in which the openings 21 to 24 for attaching the components are formed, the indoor surface material 30 in which the openings 31 to 34 for attaching the components are formed, the outdoor surface material 20 and the indoor surface material 30 A first heat insulating member 61 that is disposed between the paper core 50 and the door tip side of the door body 10, and that separates the space communicating with the openings 21 to 24 and the openings 31 to 34 from the paper core 50. 2 heat insulating material 62, 3rd heat insulating material 63, and the lower heat insulating material 64 arrange | positioned so that the door-end core material 44 and the paper core 50 may be separated between the 1st heat insulating material 61 and the lower end part of the door body 10. .

Thereby, even when water penetrates into the inside of the door body 10 from the openings 21 to 24 and the openings 31 to 34, the openings 21 to 21 are formed by the first heat insulating material 61, the second heat insulating material 62, and the third heat insulating material 63. Since the space which communicates with 24 and the opening parts 31-34 is separated from the paper core 50, the situation where the paper core 50 gets wet with water is prevented reliably.
Further, even when water reaches the lower side of the first heat insulating material 61 through the surface on the hanging base side of the door core material 44, the bottom extending from the lower surface of the first heat insulating material 61 to the lower core material 42 is lowered. Since the door core material 44 and the paper core 50 are separated by the side heat insulating material 64, a situation where the paper core 50 touches water is prevented.

  Further, since the first heat insulating material 61, the second heat insulating material 62, the third heat insulating material 63, and the lower heat insulating material 64 that function as heat insulating materials are used to constitute a structure that prevents the paper core 50 from getting wet, Compared with the case of processing the core material and attaching the drainage structure separately, the productivity is high.

  The lower heat insulating material 64 as a partition member of the present embodiment is made of EPS (Styrofoam) which is a thermoplastic resin. Moreover, the 1st heat insulating material 61, the 2nd heat insulating material 62, and the 3rd heat insulating material 63 as an enclosure member of this embodiment are comprised with a nonflammable thermosetting resin.

As a result, the spaces communicating with the openings 21 to 24 and the openings 31 to 34 are surrounded by a non-combustible resin material, so that the room (one side space) is exposed to high temperature due to a fire, and the upper cylinder lock 92 and the lower Even if parts such as the side cylinder lock 94 fall off from the openings 21 to 24 and the openings 31 to 34, or a gap is formed in the openings 21 to 24 and the openings 31 to 34, the combustible gas remains in the opening 21. The situation which leaks outside through -24 and the opening parts 31-34 and ignites can be prevented.
Moreover, since the 1st heat insulating material 61, the 2nd heat insulating material 62, and the 3rd heat insulating material 63 which divide the circumference | surroundings of the opening parts 21-24 and the opening parts 31-34 are comprised with a nonmetallic material, it is the conventional iron-made. The weight can be reduced as compared with the surrounding core material, and it can be supported and fixed inside the door body 10 without using a fastening member such as a rivet, thereby improving the productivity.

  Furthermore, if the lower heat insulating material 64 becomes nonflammable, the door 10 is likely to warp due to a temperature difference between the inside and outside in the event of a fire. In this embodiment, the lower heat insulating material 64 is made of a thermoplastic resin. Therefore, the lower heat insulating material 64 melts and disappears at the time of a fire, and the temperature difference between the inside and outside of the room can be reduced to prevent the door 10 from warping.

  In addition to this, appropriate components are attached to the door body 110 according to the specifications. For example, a door card 166 and a box-retaining reinforcing plate 167 are provided on the inner surface of the indoor surface material 130, and a lock piece 165 is arranged according to the configuration of the handle and the number of cylinder locks.

  In addition, the paper core 50 is bonded and fixed to the outdoor surface material 120 and the indoor surface material 130 in a state where a honeycomb structure formed in a rectangular plate shape is cut and compressed according to the layout inside the door 110. . Similar to the door body 10 described above, the paper core 50 is separated from the door core material 44 by the first heat insulating material 170 and the lower heat insulating material 64 at the portion where the drainage path is formed, and thus contacts the water.
