Description

Fire door with escape way {A FIRE DOOR}

The present invention relates to a fire door having an escape port, and more particularly, to provide an easy escape by installing an escape door having a fire protection means that can protect the escape from smoke and flame until the escape to the fire door provided in the building. The provision of an improved fire door.

Fire doors are used as essential elements in fire compartments, and they are installed in most buildings to prevent fires from being transferred to other parts or other areas in the event of a fire and to partition the combustion only in the fire area.

Fire doors are mainly used where walls can be partitioned, and fire doors made of metal are installed in evacuation passages and emergency stairs, and in public spaces such as malls, underground malls, shopping malls, or in large spaces such as airports and gymnasiums. Fire shutter is used.

The installation standards for fire protection (Article 14 of the Evacuation and Fire Protection Rules) require that the structure of compartments be partitioned into fire floors, walls, fire doors and automatic fire shutters in order to maintain fire resistance for a predetermined time in case of fire.

Looking at the structure of the fire door used in a general residential building or a commercial building as described above with reference to FIG.

The general fire door (1) to which the prior art is applied is provided with a double-shaped door panel (2) in the form of a plate made of a metal plate so as to be connected to the door frame and the door hinge installed in the building to be opened and closed, the door In the intermediate position of the panel (2) it is configured by mounting the handle (3) for opening and closing the fire door (1).

Fire doors as described above are installed at the emergency exit or evacuation stairs of offices or general buildings such as restaurants, shops, etc. However, fire doors installed at the emergency exit side should be left open to limit unintended traffic. There are many cases of locking down the rules.

As such, when an emergency such as a fire occurs while the fire door of the emergency exit is locked, people in the building frequently fail to open the locked fire door and fail to evacuate to the outside safely.

As described above, when a fire door is artificially locked, a large number of personnel cannot be evacuated quickly in case of an emergency such as a fire, thereby providing a cause of not only a large number of casualties due to fire and smoke, but also a property damage. do.

If the fire door is locked at the time of the fire, rescue workers who are dispatched to extinguish the fire as well as rescuers who are put in for rescue and rescue activities are blocked from entering the building. It is impossible to rescue or to escape.

In case of fire, the fire door is closed automatically to prevent the fire from spreading further.In this state, it is not easy to open the fire door without visibility of flame and smoke, especially for the elderly. Difficulties opening the fire door.

In particular, since the flames and smoke generated by the fire are located in the upper part due to the high temperature, when the fire door is opened, the fire and the smoke are quickly transferred to another area. Diffusion occurs that prevents the evacuation effect.

In addition, it is known from experiments and research that smoke or toxic gas is at a height of about 60 cm or more from the floor in case of fire. It is not easy to hold and open, making it difficult to evacuate easily.

In the present invention, to solve the problems as described above, the exit to form a size that can escape from the lower position of the fire door, and the escape door is coupled to the escape opening, the escape door, Provision means provided in the escape door to enable the fire door and opening and closing, and provided in the escape port and escape door to block the flame and smoke during the escape process to block the flame and smoke conduction to the evacuation area, flame and smoke It is composed of helpers to prevent escapes from being damaged by it, and it is possible to easily escape through fire doors in the event of fire or emergency, and to prevent the spread of flames or smoke to other areas, thereby reducing property and casualties. It is possible to achieve.

The present invention forms an escape port so that people evacuating while maintaining a low posture in the fire door, and the escape port by preventing the flame and smoke from entering the escape port in the escape process to allow easy and safe escape It is an invention having various effects such as being able to faithfully perform the function of the fire door and minimizing human injury by providing the ease of escape from an emergency situation and contributing to the improvement of the performance and quality of the fire door.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an overall configuration diagram showing a fire door having an escape door to which the technique of the present invention is applied, FIG. 2 is a cross-sectional view taken along line A-A of the fire door having an escape door to which the technique of the present invention is applied, and FIG. The cross-sectional view taken along the line B-B of the fire door having the escape port applied will be described together.

Fire door (100) having an escape port to which the technique of the present invention is applied, at the bottom of the fire door 100 in consideration of the fact that the flame and smoke and toxic gas is located in the upper layer and the air is not close to the floor in the case of fire The escape port 101 is formed to have a size that allows a person to escape from a bent or up state, and the escape door 101 is coupled to an escape door 102 that is opened and closed.

The escape door 102 is coupled to the fire door 100 and the hinge 103 to be opened and closed, the usual locking means 104, such as a door lock that also serves as a handle to keep the closed state constantly To have.

The escape door 102 is configured to open and close in the form of a case from the upper side to the lower side or the lower side to the upper side, or in one side of the escape, preferably escape through the escape port 101 when the escape through the escape port 101. It would be desirable to allow the slide to open by moving from the lower side to the upper side so as not to be disturbed.

When the escape door 102 is opened by sliding movement from the lower side to the upper side, the escape door 102 may be configured to be slid and moved upward of the fire door 100 by mechanical means for receiving power.

This means that if the escape door 102 located at the exit 101 is in the form of a door, it is difficult to open the door in a confusing and complicated situation when the escaper is in the open position by pulling the door. If the door is pushed to the open position, the escape door 102, which is slid open in the upward and downward directions, may inadvertently impact the person evacuated from the opposite side, thereby preventing this phenomenon. It can help you to be safe and escape.

In this way, when the sliding opening from the lower side to the upper side, the ball screw is connected to the forward and reverse motor, the ball screw is coupled to the screw block provided in the escape door 102, or any of the escape door 102 Fixing the rack on one side, the rack is configured to engage with the pinion is fixed to the shaft of the forward and reverse motors installed on the fire door 100, the escape door 102 can be opened to slide upward of the fire door (100). You can do that.

The escape port 101 and the escape door 102 to block the flame and smoke in the escape process to block the flame and smoke conduction to the evacuation area while preventing the escape from being damaged by the flame and smoke in the escape process A helper 105 is further provided.

The helper 105 is provided with a spray pipe 107 having a plurality of nozzle tips 106 on the three sides of the escape port 101 to which the hinge 103 is not coupled, and the spray pipe 107 is a fire door ( When the escape door 102 is opened by connecting to the solvent tank 108 and the supply pipe 109 installed in the inner space of the solvent 100, the solvent filled in the solvent tank 108 is injected into the escape port 101 so that the flame and smoke are close to each other. Don't let that happen.

The solvent to be filled in the solvent tank 108 is preferably nitrogen gas having a non-flammable, in addition to nitrogen gas may be used if the solvent is harmless to the human body without being burned by the flame.

As a means for causing the solvent filled in the solvent tank 108 to be injected into the nozzle tip 106, the opening of the escape door 102 is sensed by a sensor to use a valve driver 110 such as a motor or a solenoid. It is configured to operate the valve 111 electrically.

In case of fire, it may be difficult to receive electricity from the building, so it is desirable to be able to supply power to the escape door 102 or the valve driver 110 by receiving electricity from the battery 112 charged with electricity. will be.

The escape door 102 or the lock means 104 may be released by the escaper directly to open, but the switch is provided with a release means and a switch for electrically releasing the lock means 104 by applying battery power The escape door 102 may be opened by pressing (or touching).

It may be possible to easily identify the position of the escape port 101 in the emergency by using a flashing means using a fluorescent strip or LED around the escape port 101 is installed escape door 102.

Looking at the process of escape in the event of fire or emergency using the fire door 100 of the present invention configured as described above are as follows.

In the normal state, the escape door 102 installed below the fire door 100 is closed so as not to be opened by using the locking means 104, so that the escape door 102 is not interfered with the use of the fire door 100. .

In this state, when a fire or emergency occurs, the fire door 100 in the open state is closed to prevent the fire from being conducted to another area. At this time, by using the escape door 102 to which the technology of the present invention is applied. It is possible to escape quickly and easily from the fire zone to the evacuation zone or the fire-free zone.

In detail, when a fire occurs, the user moves to the fire door 100 while lowering his posture, and opens the escape door 102 installed below the fire door 100 to escape to the evacuation area through the escape port 101. Just do it.

At this time, since the lock means is released by manipulating (pressing or touching) the switch provided below the escape door 102 or the fire door 100, the escape door 102 opens naturally.

The escape door 102 is opened and at the same time the helper 105 installed inside the fire door 100 operates to form an air curtain to prevent the flame and smoke from approaching the open escape 101. do.

As such, when the air curtain is formed in the escape port 101 by the helper 105, the escaper needs to move out of the escape port 101 to a safe area in a lowered posture, and the air curtain is continuously formed in the process of escape. As the person passes through it, the flame and the smoke block the proximity to the escape port 101 so that the escape is possible in a safe state.

That is, when the escape door 102 is opened, the door opening is sensed through the sensor, and the valve driver 110, which is applied thereto, opens the valve 111 to fill the solvent tank 108 installed inside the fire door 100. Is injected into the nozzle tip 106 through the supply pipe 109 and the injection pipe 107, so that the air curtain can be formed by the solvent sprayed around the escape port (101).

In addition, even in a situation where it is difficult to secure the forward clock due to the fire and smoke due to the fire, the exit 101 or the escape door 102 may be visually confirmed through the fluorescent strip around the exit 101 through the fluorescent band. Being able to easily determine the location of the will help to help escape.

The present invention has the advantage of being able to easily escape through the fire door in the event of fire or emergency while preventing the spread of flame or smoke to other areas, thereby reducing property and casualties.
