Generally, due to the appearance of a high-rise apartment, there is a limit to the way of evacuation by using a ladder of a fire truck when a fire occurs in an apartment.

Therefore, conventionally, a partition wall capable of being demolished is installed on the balcony of a apartment house or the like, so that the wall of the balcony is usually divided into the spaces between the generations, and in case of emergency such as a fire, And provides a function as an exit for escape between adjacent households.

However, since the existing barrier walls that can be dismantled should have no facilities on the balcony boundary wall in order to be able to evacuate, in reality, there are many cases where the storage spaces are installed there, so that they can not be used as a partition capable of escaping.

Also, since most of the apartments have balconies that extend or extend outside the balconies, almost all of the generations' balconies are indoors, so when the partition is removed, fire and toxic gases are transferred to the adjacent households, I also had a problem.

In addition, the outer plate of the door to which the heat is directly contacted in the fire is composed of a flat plate (hereinafter referred to as "outer plate").

However, the following problems arise when using the conventional heat shielding door constructed as described above.

First, since the outer side of the door constituting the conventional heat shielding door is constituted by an outer flat plate, when the hot air comes into contact with the outer flat plate during the fire, the outer flat plate expands and expands due to the high temperature heat. Accordingly, when a fire is generated and the outer plate of the door is inflated and expanded to both sides, both side ends of the door are distorted. As a result, a gap for introducing toxic gas is formed between the both ends of the door and the door frame, The evacuees evacuate to toxic gas frequently.

In addition, since the hinge of the conventional heat shielding door is exposed to the indoor space of the apartment house, the hinge is twisted due to the high-temperature heat being contacted with the hinge when the fire occurs, so that a gap for flowing the flow gas around the hinge is further formed I also had problems.
