Description

Fire escape room fire door

The present invention relates to a fire door for a fire evacuation room that temporarily evacuates when a fire occurs in a high-rise building, such as an apartment or a building, and more specifically, a fire resistant heat insulating material is built into the inside of the fire door, In addition, by installing a see-through window for checking the interior of the evacuation chamber, it blocks high temperature heat and toxic gases due to fire and prevents thermal deformation of the fire door, thus preventing suffocation and injury of the victims. In addition, it is a technique related to fire doors for fire evacuation rooms that increase the fire resistance of fire doors.

In general, high-rise buildings such as apartments and buildings are increasing in a city with a high concentration of population.In the case of a fire, such a high-rise building may cause fatal injury, and emergency exits and fire doors are obliged to be installed. Various means of evacuation are provided.

However, in the case of fires in most high-rise buildings, very few people are aware of how to use slumbers, so evacuation through slumbers is rarely performed, and in the case of emergency exits, smoke and toxic fumes act as chimneys. As the gas fills up, evacuation through emergency exits is also difficult.

Therefore, a fire evacuation room is known that can be evacuated until the arrival of the firefighters by those who failed to evacuate in the interior of a balcony or a high-rise building of a conventional apartment house.

Conventionally, fire evacuation rooms are installed in balconies of apartments or in high-rise buildings, and evacuation rooms are blocked around the four sides and upper and lower sides, and fire doors are provided on the interior side of the evacuation rooms for people to enter. An exit door is provided on the outdoor side of the evacuation room so that evacuated people can escape to the ground through the ladder truck.

However, after a person evacuates to the interior of the fire evacuation chamber, the heat of heat and toxic gases that spread into the room are rapidly conducted through the fire door with the entrance door closed, and the heat of conduction is immediately transferred to the interior of the evacuation room. It is influx.

Therefore, in the related art, as the heat and toxic gas of flame spreading in the room are rapidly introduced into the interior of the shelter, the toxic gas is filled inside the shelter and the internal temperature of the shelter is raised in a short time, so that the evacuator has a high temperature. You may be burned or suffocated by toxic gases.

As a representative prior art of a fire door for the fire evacuation room installed in the interior of a conventional apartment house, Republic of Korea Patent No. 10-1585378 (heat shield fire door for fire evacuation room) has been presented.

The prior art is a heat shield fire door which is installed in the evacuation room in communication with the interior of the apartment house serves as the entrance, the heat shield fire door is a door frame installed in the entrance opening of the evacuation room; A door connected to the inside and the outside of the door frame by a plurality of hinges, the door being opened and closed; And a locking means provided on the other side of the door and the other side of the door frame to close the door.

This prior art prevents both sides of the outer plate constituting the door in the event of a fire to prevent warpage of both ends of the door, thereby preventing gaps of toxic gas from entering the interior of the evacuation chamber at both ends of the door. Provides the effect of preventing suffocation.

However, in the prior art, since the fire resistance of the fire door is inferior, the safety of the evacuees cannot be guaranteed as the fire door is damaged or deformed due to the heat of flame spreading in the room, and the fire door is also transmitted to the interior of the evacuation room through the fire door. Since it does not effectively block the high temperature of the heat, there are problems that the evacuees are burned or killed.

Republic of Korea Patent No. 10-0998240. Republic of Korea Patent No. 10-1576614. Republic of Korea Patent No. 10-1585378. Republic of Korea Patent No. 10-1607895. Republic of Korea Patent No. 10-1744220.

The present invention can not guarantee the safety of the evacuator as the fire door is damaged or modified due to the high temperature heat in the prior art of the fire door for the conventional fire evacuation room, and also does not block the high temperature heat transmitted to the interior of the evacuation room As a technology designed to improve the problems of life-saving, fire-resistant heat insulating material is built in the inside of the fire door, the heat insulating space is formed on the front of the heat insulating material, and the fire evacuation room is equipped with a sight window to check the interior of the evacuation room. The purpose is to provide a fire door.

In addition, the present invention blocks the heat and toxic gas of the high temperature due to the fire, and prevents thermal deformation of the fire door, not only to prevent suffocation and injury of the victims, but also to increase the fire resistance of the fire doors The purpose is to provide.
