Abstract

The present invention relates to a fire door for an emergency escape, and more specifically, to a fire door installed on an emergency exit allowing an escape to an outer escaping apparatus or a safety area when a fire breaks out inside a building such as an apartment or the like. The fire door comprises: double doors (10, 10′); and a shield (20). The double doors (10, 10′) are installed inside and outside a wall or on an existing fire door. The shield (20) is made of a flameproof material to allow a person to escape while blocking flames, smoke, or harmful gas from flowing into the escape apparatus or the safety area in a state where the double doors (10, 10′) are opened; and has a cut line (22) cut in a radial, horizontal, or vertical direction.

Description

An Emergency exit fireproof door

The present invention relates to a fire door, and is a fire door installed in an emergency escape or emergency escape device (escape space or evacuation enclosure) for escaping to an outside or a safe area in a building such as an apartment or a building. Even if the double door is automatically opened to escape, the double doors are prevented from inflow of flames, smoke and toxic gas into the safety zone or escape device in the middle of the door, And a cut-off film formed in a shape that is cut in the horizontal or vertical direction.

In general, when there is a time to escape when there is a fire in an apartment or a building, open the fire door itself and enter the evacuation space or evacuation hull to wait for the structure. A large amount of toxic gas flows into the evacuation space and the evacuated enclosure in the process of opening and closing the hinge retractable fire door, so that even if evacuated, it is difficult to escape from the risk and suffering of suffocation due to toxic gas, and the life damage may be increased.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a fire escape door that is installed in an emergency exit or an emergency escape device for escaping to an outside or a safe area when a fire occurs inside a building such as an apartment or a building, Even when the door is open, the fire or toxic gas is prevented from flowing into the safe area or the escape device, and the person can escape, thereby minimizing personal injury.

In order to accomplish the above object, the present invention provides a fire door provided in an emergency escape opening for escaping to an escape device or a safe area in case of a fire inside a building such as an apartment or a building; A double door provided at the inside or outside of the wall or the existing fire door and a door which is installed in the middle of the double door and which prevents the entry of the flame, smoke and toxic gas into the escape apparatus or the safe area, The present invention provides a fire escape door for emergency escape which is made of a flame retardant material so as to be able to escape, and which is formed in a radial or horizontal or vertical cut-away shape.

Preferably, the double door is provided with a driving device for being opened and closed at the same time while being vertically moved up and down. The driving device is automatically opened by the detection of a sensor when a fire occurs and is manually closed from the outside when the escape of the person is completed do.

More preferably, the sprinkler and the evacuation guide are additionally provided in the blocking membrane.

The present invention can prevent a person who can not escape from escaping to a safe area in the situation where a fire is generated and toxic gas or smoke is diffused in the room and minimizes the inflow of toxic gas into the safe area when escaping, And has a useful effect of safely evacuating.

Fig. 2 is a side sectional view of the emergency escape fire door shown in Fig. 1,
Fig. 3 is a side sectional view showing a state of escaping through the emergency exit escape door of the present embodiment, Fig.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 3 show an emergency escape fire door according to a first embodiment of the present invention. The fire escape door is installed in an emergency escape opening for escaping to an escape device or a safe area when a fire occurs inside a building such as an apartment or a building With a fire door; (10, 10 ') installed in a wall or an existing fire door and a double door (10, 10') installed in the middle of the double door (10, 10 ' And a shielding film 20 made of a flame retardant material and formed in a radially cut shape so that a person can escape while blocking smoke and toxic gases from entering the escape apparatus or the safe area.

In the drawing, reference numeral 30 denotes a landing gear of the double doors 10 and 10 ', 40 is a sprinkler, and 50 is an induction lamp.

In the present embodiment, the double doors 10 and 10 'are metal doors having a built-in refractory material therein and are simultaneously opened or closed by an electric or spring-driven lifting device 30. The double doors 10 and 10' 10 and 10 'are obvious to those skilled in the art, so a detailed description thereof will be omitted.

In addition, the double doors 10 and 10 'can be controlled so that the sensor detects the fire occurrence or can be opened remotely from the central control room, and can be closed automatically or manually after the person escapes It is possible to prevent the spread of the fire and to allow the escapee who is evacuated by the evacuation space or the evacuation hull to take relief with peace of mind.

In addition, it is preferable that the outer edge of the double doors 10 and 10 'is sealed with a non-burnable sealing material so as to block smoke or toxic gases or flames from entering.

In this embodiment, the barrier film 20 may be made of a material having elasticity but not fire, such as heat-resistant silicone, or a flame retardant sheet used as a material of a fire-fighting appara- tus may be attached to the outside of such a material, Is not adhered.

As shown in FIG. 2, the shielding film 20 is kept closed to prevent toxic gas or smoke from entering the safe area. In case of emergency escape, 3, a person is allowed to pass through while being outwardly opened. After the person passes through, they are closed again by the elastic restoring force of their own, so that toxic gas or smoke flows into the safe area .

In this embodiment, the shielding film 20 has a cut-away portion 22 radially cut out from the central portion to the outside, so that when the escapee pushes the head or leg first, the portion can be opened and passed, It is closed again by the elastic restoring force of itself, and the inflow of toxic gas or smoke can be effectively blocked.

In this embodiment, the sprinkler 40 prevents water from being sprayed from the upper side to the lower side of the shielding film 20 to prevent the shielding film 20 from being surrounded by the flame or to prevent overheating, Thereby blocking the entry into the zone.

It is preferable that the sprinkler 40 is controlled to be interlocked with the opening of the double doors 10 and 10 '.

In addition, when a fire is generated when the escape lamp 50 is located in the room, it may be difficult to find an exit due to smoke or power failure. Therefore, various lamps including an LED lamp are emitted to quickly locate the escape hole The arrangement of the guide lamps 50 may be arranged outside the shielding film 20 or may be arranged in a predetermined pattern in the shielding film 20 so that the position of the escape hole and the shape of the shielding film 20 can be easily identified even in the dark desirable.

4 shows a cut-off 20 according to a second embodiment of the present invention. In the cut-off 20 according to the present embodiment, the cut-out 22 is formed in the vertical direction, As a result of the passage of toxic gas or smoke through the barrier, it is possible to prevent the toxic gas or smoke from passing through the safety zone, Can be minimized.

As described above, according to the present invention, since the door can not be opened or closed in a situation where the time of an emergency fire is compromised, after confirming the direction of the fire escape door for emergency escape with the guide light in a very low posture, Persons who can not escape unexpectedly until the toxic gas or smoke spreads in the room due to the occurrence of a fire can find out the fire escape door installed at the entrance of the evacuation space and can jump out quickly. It is possible to extend this golden time as long as possible to minimize the damage of the people.
