Description

Technology Field

[0001] The present invention relates to a method for managing escape ropes for evacuation in the event of a fire in a multi-unit residential building within the field of firefighting technology. In particular, it concerns an improved method for managing escape ropes for evacuation in the event of a fire in a multi-unit residential building that prevents casualties caused by the inability to locate the escape ropes due to poor visibility during a fire, protects evacuees gathered around the escape ropes from flames to prevent an increase in casualties, and enables smooth evacuation and rescue operations through the escape ropes. Background Technology

[0002] Generally, a rescue rope is used to escape using a rope in the event of an emergency, such as a fire, in multi-story buildings like apartments or schools, and it slows down the descent speed to prevent accidents caused by a sudden drop during escape.

[0003] The conventional descent device described above comprises a rope winding wheel mounted on a body for winding a rope, a brake drum provided on the upper body of the rope winding wheel, a deceleration wheel engaged with the rope winding wheel and coupled so that the deceleration unit is housed in the brake drum, and a housing coupled to the front of the body to seal the components. The deceleration unit is configured such that a brake housing is formed to accommodate a plurality of centrifugal brakes made of arc-shaped bars.

[0004] In the conventional descent device described above, during the emergency escape process, the rope winding wheel rotates by the rope, and the deceleration wheel engaged with the rope winding wheel rotates by the rope. During the rotation of the deceleration wheel, the centrifugal brake of the deceleration unit is centrifugally disengaged from the brake housing and comes into frictional contact with the brake drum.

[0005] In this way, frictional contact between the centrifugal brake and the brake drum restricts the rotation of the deceleration wheel, and as a result, the rotation of the rope winding wheel is restricted, so the lowering speed of the rope is limited to a certain speed range.

[0006] However, when a fire breaks out, thick smoke rises up, making it difficult to see even a short distance ahead.

[0007] Therefore, even if one has kept an eye on the location of the escape rope in advance, evacuees often panic in urgent situations, making it difficult to find the location of the escape rope, and in reality, there are many cases where people are unable to evacuate in such situations, leading to casualties.

[0008] To improve this, the following registered patent has been disclosed.

[0009] Nevertheless, there remains a problem that if evacuees who have taken refuge at the location of the escape rope gather, there is no means to protect them, and if flames strike, casualties may actually increase. Prior art literature

Specific details for implementing the invention

[0015] Hereinafter, preferred embodiments according to the present invention will be described in more detail with reference to the attached drawings.

[0016] The method for managing a descent device for evacuation in the event of a fire in a multi-unit residential building according to the present invention utilizes the configuration of prior registered patent No. 2592661 (October 18, 2023) as is.

[0017] Therefore, some of the following descriptions are based on the contents of the aforementioned registered patent.

[0018] As shown in FIG. 1, the method for managing a descent device for evacuation in the event of a fire in a multi-unit building according to the present invention is characterized by performing the following steps: a first step of providing a descent device management system for evacuation in the event of a fire in a multi-unit building and securing a certain space by installing a firewall around the descent device installed; a second step of creating a fire door in the installed firewall and installing an automatic locking device to set it to be opened and closed by a descent device controller; a third step of, when a fire is detected, the management server activates the descent device controller to expose the descent device from the descent device box and simultaneously illuminates a lamp and outputs a voice to indicate the location of the descent device; a fourth step of, simultaneously with the third step, the descent device controller releases the automatic locking device to open the fire door; and a fifth step of, simultaneously with the fourth step, the management server notifies the registered resident of the fact of the fire and the location of the descent device through a registered terminal.

[0019] In addition, the present invention may further perform a sixth step of illuminating a plurality of guide lights installed on the floor surface of the corridor leading to the escape device after the fifth step.

[0020] Then, evacuees can quickly follow the guide lights to a safe zone through the fire door and evacuate to the ground using a rescue rope.

[0021] In addition, a fire detector may be further installed on the firewall, and a seventh step may be further performed in which fire extinguishing water is sprayed through a fire extinguishing water spray nozzle installed on the firewall in accordance with a control signal from the escape device controller when the fire detector detects a fire.

[0022] This involves spraying fire extinguishing water to protect against the risk of flames entering the fire wall and causing casualties. To this end, a branch pipe branched from the fire extinguishing water pipe is connected to the fire extinguishing water spray nozzle, and configured to be opened and closed by a solenoid valve, allowing the escape device controller to control the opening and closing of the solenoid valve.

[0023] Here, a system having configurations for implementing the above-described method is like the example in FIG. 2 and FIG. 3.

[0024] According to FIGS. 2 and 3, the escape device management system for implementing the present invention comprises: a management server (100) installed in a management room of a building; a registration terminal (200) equipped with a dedicated app that operates in response to a specific signal transmitted by the management server (100); an escape device controller (300) provided in an escape device box (BOX) in which escape devices installed on each floor of the building are stored and wired to the management server (100); a lamp (310) installed on the escape device box (BOX) to be turned on and off according to a control signal of the escape device controller (300); a speaker (320) installed on the escape device box (BOX) to provide voice guidance on evacuation locations according to a control signal of the escape device controller (300); and a fire door that automatically locks and opens according to a control signal of the escape device controller (300). It includes an automatic locking device (330), a guide light (340) installed in a corridor and illuminated to guide evacuees to a location equipped with a descent device according to a control signal from the descent device controller (300), a fire detector (350) installed in a firewall with a fire door that detects a surrounding fire and outputs it to the descent device controller (300), and a solenoid valve (360) installed in a fire water pipe to open a fire water spray nozzle installed in the firewall and spray fire water according to a detection signal from the fire detector (350).

[0025] At this time, the registered terminal (200) is a terminal registered with the management server (100), and the smartphone information owned by the resident of the building is registered, and the principle is to register all residents.

[0026] In particular, the registration terminal (200) is designed to have a dedicated app installed that is activated in case of emergency to guide evacuation, and the activation code is transmitted from the management server (100).

[0027] In addition, the registration terminal (200) is classified and managed by floor occupied in the building and is configured to communicate through a mobile communication network.

[0028] In addition, the management server (100) is configured to analyze fire information obtained through fire detectors installed in various places of the building and to control the escape device controller (300) at the corresponding location.

[0029] In addition, since the above-mentioned escape device controller (300) is connected to the management server (100) via a wire, the management server (100) can immediately control the escape device controller (300) corresponding to the location of the fire.

[0030] In addition, the firewall effectively separates areas to prevent tampering with the escape ropes, and the fire doors are controlled to remain locked under normal circumstances.

[0031] A space partitioned by a firewall that is large enough for at least five adults to enter is sufficient, and as they arrive, they should descend to the ground using a rescue device, and the rest should assist the evacuees in descending and guide those evacuating.

[0032] Meanwhile, emergency escape devices are installed in the main windows of each floor of the building, and these devices are built into an emergency escape device box.

[0033] At this time, a pair of lamps (310) are installed on both sides of the front of the above-mentioned escape device box (BOX), and a speaker (320) is provided at a distance from the lamps (310).

[0034] In addition, the above-mentioned escape device controller (300) is driven by commercial power.

[0035] The present invention configured in this way allows the management server (100) to detect a fire through various fire detectors when a fire occurs.

[0036] Then, the management server (100) recognizes which floor and which part of the building the fire has occurred on, and at the moment the recognition is complete, lists the occupants of the corresponding floor and transmits a specific code to the registration terminal (200) of the listed occupants.

[0037] Accordingly, the registration terminal (200) of the resident of the floor is activated, and the dedicated app is executed, and the dedicated app displays and provides guidance on the nearest escape device to the floor.

[0038] At the same time, the management server (100) transmits a control signal to light up or flash the lamp (310) of the escape device box (BOX) near the fire source on the floor where the fire occurred, and also controls the speaker (320) to output a voice to indicate the location.

[0039] Therefore, a resident carrying a registration terminal (200) can easily and quickly find the escape device box (BOX) by listening to the light and sound, even if it is difficult to see ahead due to smoke, and can open the escape device box (BOX) and take out the escape device to escape.

[0040] In this case, it is preferable that the escape device boxes (BOX) be guided sequentially starting from the one closest to the registration terminal (200).

[0041] On the other hand, it is preferable to implement the above firewall by stacking blocks and plastering, and the blocks are molded with concrete mortar, and the concrete mortar is composed of 20-25% by weight of cement, 30-35% by weight of sand, 20-25% by weight of gravel, 10-15% by weight of functional admixture, and the remainder being water.

[0042] At this point, sand, gravel, and water are basic components, so the explanation for them is omitted.

[0043] And, the above functional admixture consists of 4.5 wt% sodium hydrogen orthophosphate, 10 wt% n-BMA (n-Butyl methacrylate), 10 wt% tebuconazole, 4.5 wt% pyromellitic dianhydride, 20 wt% monocarboaluminate, 15 wt% 2-phenylimidazole, 15 wt% phosphite ester, and the remainder octylacrylamide.

[0044] Here, sodium hydrogen orthophosphate enhances crack resistance, erosion resistance, and corrosion resistance.

[0045] Also, n-BMA (n-Butyl methacrylate), also known as 2-propenoic acid, is an organic synthetic material that enhances elongation and flexural strength, contributing to the suppression of cracks and fissures in slabs.

[0046] In addition, Tebuconazole inhibits mold growth and enhances dispersion stability.

[0047] In addition, pyromellitic dianhydride enhances slip properties, thereby increasing antifouling properties and increasing erosion resistance.

[0048] In addition, monocarboaluminate prevents cracking of the slab and prevents shrinkage of the slab, thereby increasing durability.

[0049] In addition, 2-phenylimidazole contributes to inhibiting cracking by reducing drying shrinkage.

[0050] In addition, phosphite ester contributes to increasing the resistance to corrosion caused by chlorine components, thereby preventing crack resistance.

[0051] In addition, octylacrylamide enhances water resistance by increasing water tightness. Explanation of the symbols
