Abstract

The present invention relates to a device which helps people to go down the side line stairs through a rooftop and escape to the ground when a fire occurs in an apartment and a building. An electronic device is installed to open a fire door (It is locked always) automatically. An automatic key drop unit is installed if the electric device has some troubles and does not operate. The device of the present invention has a light and an exit sign to help people to go to the side line at the rooftop and to go down to the ground safely. At worst, the device helps people to pull an emergency rope and to receive a key and to open a door and to go out if all things do not operate. If the key comes down due to play of children, an automatic alarm operates and a control office can grasp the situation.

Description

{Apartment in case of fire doors, roof automatic opening device}

It is an electric fire safety field that opens the road by automatically operating the fire door so that it can be evacuated to the roof and the ground when an apartment fire occurs

To date, the roof doors of apartments and buildings have been locked at all times and are being used as "fire doors" to prevent the spread of fire and doors used by the staff of the apartment management office as inspection vehicles. Especially, in order to quickly evacuate through the roof fire door in case of fire, we devised automatic fire door opening system for the roof fire door to cope with the reality that it can not deny that the precious life is sacrificed much because the escape route is not secured. .

* Daeongbong Green apartment fire accident in Uijeongbu (2015) ·

* Namyangju East Centerville fire accident (2015) ·

* Yangzhou GS Zai apartment fire accident (2015)

In the event of a building fire, people downstairs from the point of fire occurrence are naturally easy to evacuate to the ground. However, people who are above the fire point may be difficult to evacuate to the ground. At this time, the roof fire door is opened from the beginning of the fire alarm, and the fire door is opened up through the open fire door to escape to the roof. (Which is also open from the very beginning of the fire alarm) to the stairs and to help them evacuate to the ground to protect their precious lives from fire

It has been installed and operated in 3 apartments and 5 lines currently working on the project. By installing a fire door that is automatically opened when a fire occurs, it can be used as an emergency door that opens automatically when a fire occurs, allowing people to evacuate, such as a door opener, an end opener, (LED10w * 3 pieces), fire wire and railway. It can be installed at low cost,

When the fire alarm is activated in the receiver, which is a fire alarm system (in case of a fire), the emergency power source, in which the emergency light and the guide light are lit in the stairs and corridor of the whole building, To open the door to evacuate people from the flames.

Also, it is possible to resolve the dispute between "blockade" and "open" with the roof fire door between the police station and the fire station by eliminating the disagreements between the residents of the upper floors and the management office, which are caused by the roof door being permanently locked.

In the case of fire, the automatic opening device of the fire door on the roof is used to reduce the damage of the life span by using the electric opening device, the terminal opening device, the key automatic transmission device (Built-in) LED10W bulb, so it can be installed at low cost.

Hereinafter, the present invention will be described in detail with reference to the attached drawings and the evacuation instructions.

Fig. 1 is an electric circuit of a simple fire door automatic opening device for automatically opening a roof fire door when a fire occurs and allowing people to evacuate to the roof and the ground.

FIG. 2 is an electrical circuit diagram of a device for evacuating persons to the roof top, as shown in FIG. 1, from a rooftop space to a side roof fire door by lighting in a rooftop space and safely escaping to the ground along the stairs.

FIG. 3 is an electronic device for manually opening the door by automatically releasing a fire door (key) in case the automatic fire door has not been operated as a mechanical or physical failure as a whole.

Fig. 4 shows the structure of the automatic keying mechanism, the operating principle, and a map of the installation position.

FIG. 5 is a circuit diagram of a fire alarm key auto-ignition operation status alarm device in the event of a fire

In this figure, open circuit contacts O and D are connected to constitute a circuit so that the alarm operates.

In the event of a fire, the area from the rooftop fire door, rooftop space, and side line fire doors is an unfamiliar space for almost everyone except the building manager, so especially bright lights and induction facilities If the fire escapes through the fire door before the fire, people will not be harmed, but the fire will rise to the rooftop due to the structural characteristics of the building, so if the fire door is opened from the beginning of the fire alarm, In order to overcome this, the escorts were installed manually and fully opened by the cylinder which was constructed so that the fire door could not be opened even if the fire door was opened by itself or the electric key was opened.

When the fire alarm system is activated, the fire door is opened by the O and A contacts at the time of opening the fire door of the roof, that is, from the moment when the automatic opening of the fire door is activated when the fire occurs, 4, in case of a fire, automatic keying is activated by an emergency power source to release the key. At present, the cylinder key hole of the fire door is closed with a seal cone and installed only to serve as a cylinder. The purpose of the HY-h707c 10A-250v circuit is to prevent fire from entering the door when people open the door by fire door automatic door opener operation. (30 ~ 40m) between the fire door on the roof of the fire line and the fire door on the side of the side (30 ~ 40m) with LED10W / 220v 3EA lighting And lighted with two lines on both sides of the evacuation route with a Christmas tree or the like so as to evacuate quickly without departing from the path.

Automatic keying when a fire occurs The purpose of the installation is to automatically open the door with the key down to the automatic keying operation even in the worst case where the emergency door automatic opening device is not opened automatically due to an electrical and physical mechanical malfunction, . If the keying device does not work and the key does not come down, it is structurally installed so that the key is lowered to the keyhole of the fire door when the line on the bottom is pulled. When the outsole is opened, a circuit is formed by the end opening, and the uppermost layer earth alarm is turned on and the fire alarm system installed in the management office is operated so as to operate. This is a warning to control the opening of the fire door due to intentional forced operation Device,

Each drawing is explained.
