The packing member 420 is a part that is elastically deformed in contact with an end portion of the side surface of the step portion B2 of the door D when the door D closes the entrance, and the third packing member ( 430 is a portion that is elastically deformed in contact with the left and right sides of the side of the body portion (B1) of the door (D) when the door (D) closes the entrance.

By providing the first packing member 410 to the third packing member 430, the interior side and the door frame 1000 of the body portion B1 of the door D when the door D closes the doorway. Gaps between, the interior side of the step B2 of the door D and the gap between the door frame 1000 and the left and right sides of the body part B1 of the door D and the interior side of the door frame 1000. The gap between the sides can be eliminated in triplicate, which further improves the isolation against the temperature difference and the wind between the indoor and outdoor, and as a result, further improves the airtightness, sound insulation and insulation between the indoor and outdoor. .

According to the above, the present invention provides a heat insulating member to prevent direct mutual contact between the outdoor frame and the indoor frame, so that the outdoor heat is transferred to the indoor side along the door frame or the indoor heat is transferred to the outdoor side. Minimization can increase insulation.

In addition, the present invention is configured so that the ends of the outdoor frame and the indoor frame is fixed to a portion of the heat insulating member, it is easy to manufacture a simple structure and can reduce the production cost.

In addition, the present invention can further improve the thermal insulation effect by having an air storage space.

In addition, the present invention can be provided with a plurality of packing members, it is possible to minimize the gap between the door and the door frame, thereby improving the isolation between the indoor and outdoor against the temperature difference and wind between the indoor and outdoor. As a result, the present invention can improve heat insulation.

In addition, the present invention is configured to surround a portion of the heat insulating member by the stainless steel-based outdoor frame and the indoor frame, it is possible to minimize the thermal deformation of the door frame in the event of a fire or to prolong the time required for thermal deformation. For this reason, the present invention can prevent a safety accident due to deformation of the door frame when a fire occurs.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, . ≪ / RTI > Accordingly, such modifications are deemed to be within the scope of the present invention, and the scope of the present invention should be determined by the following claims.
