Description

Fire safety evacuation system for apartment houses in case of fire}

The present invention relates to a fire safety evacuation system of an apartment house in the event of a fire in the field of fire fighting technology. It relates to a fire safety evacuation system of an apartment house in the event of a fire that has been improved to reliably protect residents from fire by preventing human accidents that occur while trying to use it despite the absence of it.

In general, an apartment house is equipped with an entrance door, a veranda is installed inside the living room, and a safety handrail for preventing falls is installed on the veranda.

However, recent high-rise apartments (30 floors or more) and residential-commercial complexes have the advantage of being able to overlook the surrounding landscape from the inside and the advantage of being able to have various convenience facilities inside one building. If suppression is difficult, there is a disadvantage that leads to great property damage as well as human life.

Of course, if the main entrance and exit are open at the time of the first fire, escape may be attempted through the main entrance and exit.

However, if the emergency exit and the main entrance door are blocked by fire, there is a problem that the residents trapped in the apartment building must wait for death while being trapped or jump over the safety railing to prevent falls as a last resort.

On the other hand, in order to solve this problem, there is a way to avoid the body from the fire by using a descender installed on the veranda, but the above descending machine has problems such as being difficult to operate and unreasonable for the general public to use. Due to the burden of carrying the user's weight, there is a limit in that the user cannot shake off the fear caused by fire and the anxiety caused by using the descending device.

In addition, a firefighting system for detecting and extinguishing a fire in a building such as an apartment building is provided.

The conventional firefighting system as described above includes a detection unit for detecting the occurrence of a fire, a control unit for activating an alarm system or operating a sprinkler and a fire shutter when the occurrence of a fire is detected by the detection unit, and a sprinkler operated by the control unit. It is composed of the firefighting equipment department, etc.

These are designed to extinguish the fire by spraying fire extinguishing water at a set location when a fire occurs.

Since each household in the apartment house having such a system does not have any information vulnerable to fire in each home in the apartment house, it is difficult to quickly extinguish a fire when it occurs.

In particular, in the case of households, various types of fire detectors are provided, but there is no means to detect fires occurring at stair landings other than households, so countermeasures for this are also required.

In addition, there is no way to check whether the inside of the elevator is burnt down in the event of a fire, so if you make a mistake, a large-scale accident may occur during the elevator boarding process.

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

The system according to the present invention can monitor not only the inside of the household, but also the external stair landings of the household and the fire occurring outside each building, and through this, if a fire affects the building, whether inside or outside the household, immediately Evacuate, but provide an evacuation facility system that can safely evacuate until the final rescue.

Therefore, in the system according to the present invention, a detection structure is implemented to have detection characteristics including fire detectors installed in each household as well as fire detectors installed outside the household, and an evacuation route is implemented in conjunction with the detection structure, and an evacuation facility is It is designed to be driven.

More specifically, as shown in the examples of FIGS. 1 to 3, a fire alarm detector 100 installed at a fire hydrant in each household of an apartment house, an alarm 110 mounted on the fire alarm detector 100, and the fire alarm detector A heat detector 120 connected to 100 and installed in each household, a smoke detector 130 connected to the fire alarm detector 100 and installed in each household, and a memory mounted on the fire alarm detector 100 A built-in alarm controller (CTR), a sound detector 140 controlled by the alarm controller (CTR) and recognizing a specific frequency, and a sound detector 140 installed at the landing of each household and detecting a fire in the event of a fire. A detection alarm 700 outputting a bell sound, a management server 300 connected to the alarm controller (CTR) and operating the fire alarm detector 100 through the corresponding alarm controller (CTR) when a fire occurs, and a rooftop for each building The roof door lock 200 installed on the door and opened according to the control signal of the management server 300 in case of fire, and the shelter 400 provided on the roof of each building according to the control signal of the management server 300 in case of fire It includes a shelter electronic lock 400 that converts to a drivable state.

At this time, it is preferable that the fire alarm detector 100 has water resistance, waterproofness, and antifouling property to enhance corrosion resistance to achieve longevity, and further to have heat resistance and fire resistance so as not to be vulnerable to fire.

To this end, the outer surface is based on 100 parts by weight of liquid melamine resin, 25 parts by weight of aluminum hydroxide, 10 parts by weight of zirconium, 15 parts by weight of boron nitride, 10 parts by weight of sericite powder, 5 parts by weight of isocyanurate, decarburization It is coated with a coating solution in which 15 parts by weight of lithium powder, 15 parts by weight of silicon carbide powder, and 10 parts by weight of pyrometric acid are mixed.

In this case, the liquid melamine resin is added to strongly suppress surface peeling of the coating layer and enhance fire resistance by maximizing adhesive strength, and the aluminum hydroxide prevents hydrophobicity of the polymer and induces hydrophilization to increase bonding strength and enhance incombustibility. The zirconium is added to increase fire resistance, corrosion resistance, and incombustibility by forming a protective film made of oxide or nitride by combining with oxygen in the air in the event of a fire.

In addition, boron nitride is added to enhance heat resistance by increasing the thermal conductivity of bricks to effectively reflect heat and maintaining heat dissipation through this, and sericite is a hydrophilic mineral that doubles the adhesive force by expanding the bonding area to the surface. It is added to enhance durability by strengthening binding properties.

In addition, isocyanurate is added to minimize the formation of bubbles in the dough, remove bubbles, and increase impact resistance and weather resistance; Tantalum, as a transition metal, has an acid-resistance function, which enhances antifouling and erosion resistance.

In particular, silicon carbide is added to enhance heat dissipation adhesiveness and, above all, to suppress shrinkage deformation during molding; Pyromethric acid is added to suppress heat shrinkage and enhance slip properties to improve moldability during molding of raw materials and to improve durability.

On the other hand, as shown in the example of FIG. 4, the detection alarm 700 is configured as a mobile type so that it can be operated without commercial power.

The detection alarm 700 shown in FIG. 4 includes an alarm case 710 having an enclosure shape, a flame detection unit 720 protruding from the center of the bottom surface of the alarm case 710, and a A fixing block 730 fixed to the inner ceiling surface, a square bar 740 hinged to the center of the bottom surface of the fixing block 730, and a spring (SP) bound to the lower end of the square bar 740 , A wire 750 fixed to the end of the spring SP, a striking weight 760 bound to the lower end of the wire 750, and disposed on both sides within the rotation radius of the striking weight 760, and the alarm A pair of alarm bells 770 fixed to the inner bottom surface of the case 710, coupled to the center of the lower end of the strike weight 760, extended and penetrating the flame detection unit 720, and then bound to the strike weight ( 760) arranged and fixed in the direction of gravity so as not to move, and a pair of first and second pairs disposed on the square bar 740 in the form of an N-pole and an S-pole and fixed at an interval up and down. Magnets 790 and 792, and a third magnet M3 fixed to the inner wall surface of the alarm case 710 and arranged so that the N pole is opposite to the N pole of the first magnet 790 so that repulsive force acts on each other; A fourth magnet (M4) connected and fixed to the lower side parallel to the third magnet (M3) in the same form and an S pole opposite to the S pole of the second magnet (792) are positioned so that repulsive force acts on each other. A fifth magnet (M5) arranged and fixed to the inner wall surface of the alarm case 710, and a sixth magnet (M6) fixed in parallel with the fifth magnet (M5) in the same shape on the upper side. do.

At this time, it is preferable that a plurality of through holes 722 are formed on the circumferential surface of the flame detection unit 720 .

This is to directly transfer heat toward the binding thread 780 as much as possible when heat is transferred by the flame so that the binding thread 780 can be easily broken.

In addition, a plurality of through-holes 772 are also formed on the circumferential surface of the alarm case 710 where the alarm bell 770 is installed, so that the sound of the bell spreads far and wide.

Thus, when the binding thread 780 is broken due to a fire, the spring SP pulled to some extent by the binding thread 780 is restored by the shock and the wire 750 is shaken, which is a striking weight having weight. 760 is moved like a pendulum movement to hit the alarm bell 770 and sound an alarm.

In this process, since a repulsive force is generated between the magnets, the striking weight 760 repeats the striking action while moving back and forth for a considerable time after hitting.

Due to this, an alarm sound is issued sufficiently, and this alarm sound is detected by the sound detector 140 of the fire alarm detector 100 installed at the fire hydrant, which is an adjacent location, and when the sound detection is completed, the alarm controller (CTR) manages the server ( 300) to transmit that a fire has occurred.

At this time, since the alarm controller (CTR) and the management server 300 are connected by wire, it is possible to immediately check which building a fire has occurred in, and promptly evacuate residents by issuing the corresponding alarm 110. do.

In particular, since the roof door is mainly locked with an electronic lock to block the escape of teenagers, the management server 300 that confirms the fire unlocks the rooftop door lock 200 connected by wire to the alarm controller (CTR) of the corresponding building.

In this case, the rooftop door lock 200 is connected in parallel to the alarm controller (CTR) for each household in the building and is configured to give a lock release signal through the alarm controller in any place, which prevents malfunction in advance in case of an emergency. in order to block

Therefore, in general, it is basic that the management server 300 controls to give a signal to open the rooftop door lock 200 through the alarm controller that sends out the emergency signal.

In addition, when a fire occurs, the management server 300 activates the shelter electronic lock 400 in a wireless communication method.

Of course, it is activated even if people evacuated to the rooftop in an emergency press an emergency power button (not shown) provided in the shelter 410 provided on the rooftop.

Therefore, the shelter electronic lock 400 is equipped with a wireless communication module to enable wireless communication with the management server 300, and a unique code is assigned to each management to receive a fire outbreak signal and know in which building the fire occurred. The server 300 activates the shelter electronic lock 400 provided on the rooftop of the building.

At this time, the shelter electronic lock 400 is provided in the shelter 410 installed on the roof, as shown in the example of FIG. 3 .

The shelter 410 is in the form of an elevator, and is configured to be able to go up and down along a ball screw 420 installed from the ground to the roof on one side of each building and a guide rod 430 installed in parallel with the ball screw 420.

In this case, the outer surface of the shelter 410 is coated with fire prevention liquid, a door 440 is provided to allow boarding, and emergency power is installed in the basement of the building.

Emergency power is an emergency power generation system, not apartment commercial power, and is driven by the emergency power button switched by the shelter electronic lock 400.

Therefore, even if the corresponding copper is lost, it can be safely driven.

In addition, when emergency power is applied to the driving of the shelter 410, the control panel 450 exercises full control power, and as with the elevator, the driving motor M is driven by selecting and pressing the button on the first floor or on the roof after boarding. As it is, the gear box (G) operates so that the shelter 410 can go up and down riding the ball screw 420.

As such, the present invention can reduce human casualties because fire detection and evacuation can be performed together.

In addition, the loss detector 10 as shown in the examples of FIGS. 5 and 6 is further installed inside the elevator, but the loss detector 10 is equipped with a short-range wireless communication module as a heat sensor, so that when a fire is detected, a specific signal is unconditionally It is configured to output.

Then, the shelter electronic lock 400 installed on the tower of the elevator is set to receive the specific signal, and as soon as it receives the signal, it immediately recognizes that it is a fire and sends a signal to the management server 300 to respond immediately.

In this case, since the signal transmitted by the shelter electronic lock 400 includes a unique code, that is, an identification code, the management server 300 can immediately know which elevator has been burned down.

Here, since the loss detector 10 sent a detection signal means that the inside of the elevator was overheated and burned due to a fire, it is determined that it was lost.

On the other hand, in the present invention, it is characterized in that the disappearance detector 10 is configured to be detachable and can be installed without drawing commercial power through a replaceable battery usage method so that the installation location is not limited.

To this end, the present invention includes a fixing unit 50 so that the loss detector 10 can be easily separated and mounted.

The fixing unit 50 includes an attachment sheet 51 fixed to the inner wall of the elevator, a cover 52 attached to the attachment sheet 51, a base housing 53 covered with the cover 52, and , the protruding part 54 protruding in a rectangular shape from the opposite surface of the cover 52 of the base housing 53, the pin fixing part 55 protruding again at a distance from each other on the surface of the protruding part 54, and the pin go A fixing pin 56 fixed across the top 55, a 'c'-shaped insertion piece 57 inserted into and bound to the fixing pin 56, and the insertion piece 57 are integrally formed and disappear A piece base 58 screwed to the lower surface of the sensor 10, and one side of the insertion piece 57 when it is embedded in the base housing 53 and the insertion piece 57 is inserted into the fixing pin 56 It includes a locking member 59 that is inserted into and fixed.

At this time, the adhesive sheet 51 is a gel type sheet.

Unlike general adhesives, this adhesive sheet 51 is not liquid, has high fixing power, and strong waterproof, heat resistance, antifouling, erosion resistance, weather resistance, and water resistance, so that it does not easily deteriorate even when used in an external environment for a long time, and thus achieves long lifespan. It should be structured so that

Otherwise, it is easily deteriorated and easily detached from the attachment surface or cracks are generated and fall off.

In addition, if the adhesive strength is too strong, for example, if it is rigidly cured like an instant adhesive, the fixing strength is very high, but there is a limit in damaging the adhesive surface, so there is a disadvantage in not achieving long life.

To this end, the adhesive sheet 51 is composed of 5 parts by weight of ethyl acetate, 25 parts by weight of hydrocolloid, 10 parts by weight of PEBAX (Polyether-block-amide), 5 parts by weight of triphenylphosphine, CZ based on 100 parts by weight of epoxy resin. After mixing 5 parts by weight of (N-cyclohexybenzothiazole-2-sulfenamide), 5 parts by weight of sodium xylenesulfonate, 5 parts by weight of 2-phenylimidazole, 10 parts by weight of polytetrafluoroethylene, and 15 parts by weight of silicone resin, calender After ringing, what was molded into a sheet shape is used.

Here, ethyl acetate is added to ensure uniformity of the surface and back surface by preventing the mixture from being entangled or finely dispersed in the process of dispersing the mixture.

In addition, hydrocolloid is added to make a gel-like sheet and maintain a wet state to determine the adhesiveness for a long time, and it is possible to secure flexibility as well as waterproofness.

In addition, PEBAX (Polyether-block-amide) has a small change in hardness even at low temperatures, excellent fatigue resistance, maintains buffering properties and increases deformation inhibition, and has excellent molding processability due to its low specific gravity, low hygroscopicity, and bending resistance. Increases fatigue, weather resistance, flexibility, creep resistance, and adhesion.

In addition, triphenylphosphine enhances weather resistance, enhances water pressure resistance and waterproofness through surface homogenization, and increases adhesion.

In addition, CZ (N-cyclohexybenzothiazole-2-sulfenamide) is intended to increase antifouling function. In addition, sodium xylene sulfonate is added to increase adhesion stability and prevent fluffing. In addition, 2-phenylimidazole is added to reduce the drying shrinkage to prevent deformation of the gel-type sheet and to maintain a smooth surface in a smooth state to increase foreign matter adhesion inhibition.

Furthermore, polytetrafluoroethylene is a polyfron PTFE-D (Dispersion) having a structural formula (-CF2-CF2-)n, which increases durability and adhesion by increasing lubricity as well as heat resistance. Lastly, the silicone resin increases adhesion, fixation, and adhesion, and enhances stain resistance and water pressure resistance.

On the other hand, the inside of the base housing 53 is empty, and a hole is formed in the protruding portion 54, so that the locking member 59 is built in so as to be able to appear and retract.

At this time, the locking hole 59 is formed on the outer surface of one side of the insertion piece 57 protruding from one side of the locking block 59a sliding inside the base housing 53 and the locking block 59a. A locking hook 59b caught in the locking groove 57a, a spring bar 59c protruding on the opposite side of the locking hook 59b, and inserted into the spring bar 59c and hooked on the inner wall of the base housing 53 and a coil spring 59d for elastically supporting the locking block 59a, and an operating bar 59e protruding from the upper surface of the locking block 59a and exposed through one side of the base housing 53. include

Thus, when the insertion piece 57 is inserted into the fixing pin 56, the locking hook 59b is caught in the locking groove 57a so that the insertion piece 57 is not separated, and when separating, the operating bar ( When 59e) is removed, the coil spring 59d is compressed and the hook 59b comes out of the locking groove 57a, so that the insertion piece 57 can be separated.

In this way, it is convenient to install and use because it can be easily assembled, fixed, separated, and dismantled, and has the advantage of being freely installed in vulnerable areas such as inside the elevator to monitor fire.
