Description

Technical Field

[0001] This invention relates to fire protection facility technology, specifically to a fire escape route device for high-rise buildings with external fireproof and internal heat insulation. Background Technology

[0002] With the acceleration of urbanization, the number of high-rise buildings is increasing year by year. High-rise building fires, due to their high frequency, heavy economic losses, and high risk of casualties, have become a pressing social safety problem that needs to be solved. Currently, the conventional escape methods for high-rise buildings mainly rely on internal fire escape routes and fire elevators. However, these often have many fatal flaws when a fire occurs: On the one hand, the high-temperature, toxic, and dense smoke generated by the fire can easily spread to the fire escape routes, destroying fire and smoke control zones and causing suffocation and death to escapers due to inhalation of toxic fumes. Even if some buildings are equipped with fire-resistant partitions, it is difficult to achieve a comprehensive fire and smoke control effect. On the other hand, fires can easily cause power outages in buildings. Conventional emergency lighting relies on backup power. If the backup power fails, visibility in the escape routes will be obstructed, further hindering the escape process.

[0003] Existing high-rise escape equipment, such as escape slides and high-altitude descent devices, either have limited applicability, failing to meet the escape needs of vulnerable groups such as the elderly, the infirm, the disabled, and pregnant women, or are structurally complex, inconvenient to install, and lack effective fireproofing and heat insulation design, making them prone to structural damage in high-temperature fire environments and unable to provide a safe escape route. Furthermore, most escape devices rely on external power supply, failing to function properly when power is interrupted during a fire, further reducing the reliability of escape. Therefore, developing a high-rise building fire escape route device that is simple in structure, easy to install, possesses both external fireproofing and internal heat insulation functions, and can function normally without external power supply, is crucial to solving the current challenges of high-rise fire escape.

[0004] Chinese invention patent CN106310548A discloses a fire escape route, which includes a vertical column with a water tank fixed at its base. A spiral escape route is fixed on the column, with several entrance channels connected to it. A spiral water pipe is fixed to the outer wall of the escape route, and water outlets are formed on the water pipe and the escape route. The bottom end of the water pipe is fixed to a water pump, which is installed in the water tank. This invention has a simple structure, is easy to manufacture, and is suitable for escape during fires. It can also be installed in existing buildings to avoid the defects of buildings not having escape routes during construction. However, in this patent, the spiral escape route cannot quickly complete the escape of a large number of people, meaning the escape efficiency is low and it takes a long time for all people to escape. Therefore, a new type of escape device is needed to solve this problem. Summary of the Invention

[0005] The purpose of this invention is to provide a fire escape passage device for high-rise buildings with external fire protection and internal heat insulation, so as to solve a series of problems in fire escape in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a fire escape passage device for high-rise buildings with external fire resistance and internal heat insulation, comprising an elevator tower, multiple escape devices, and the building's original fire escape passage; the elevator tower is located on one side of the high-rise building and is used to allow escaping personnel to descend to the ground to complete their escape; multiple escape devices are correspondingly arranged between the stairwells on each floor of the building and the elevator tower, for connecting the fire escape passage and the elevator tower; each floor of the fire escape passage has a stairwell window corresponding to each escape device, and the stairwell window is correspondingly arranged with the escape device, allowing escaping personnel to enter the escape device from the fire escape passage and then escape through the elevator tower; the escape device includes an escape passage, and the end of the escape passage near the stairwell window is provided with a first escape door, which is aligned with the stairwell window, allowing escaping personnel to open the stairwell window and then open the first escape door to enter the escape passage.

[0007] Furthermore, the escape device also includes a steel bracket, which is fixedly connected between the elevator tower and the wall of the high-rise building to support the fixed escape passage; the escape passage is a closed passage structure with both ends connected, one end connected to the entrance of the elevator tower, and the other end corresponding to the corridor window.

[0008] Furthermore, a second escape door is provided in the middle section of the escape passage. The second escape door can be opened and closed to prevent smoke and dust from entering the side of the escape passage near the elevator tower, providing a safe waiting space for escaping personnel.

[0009] Furthermore, a solar panel is fixedly installed on the outside of the escape passage, and an emergency light is installed inside the escape passage. The solar panel is electrically connected to the emergency light to supply power to the emergency light when the building's power is interrupted, thereby providing lighting inside the escape passage.

[0010] Furthermore, the first escape door adopts a push-pull or swing-open structure, and is equipped with a handle for easy opening by escaping personnel. A sealing strip is provided at the connection between the first escape door and the escape passage to enhance sealing performance and reduce the entry of smoke and dust.

[0011] Furthermore, the elevators installed in the elevator tower are fire-resistant elevators. The elevator's operating power system uses an independent backup power supply to ensure that the elevator can operate normally in the event of a fire. In addition, the elevators are equipped with smoke sensors and emergency ventilation devices to further ensure the safety of people escaping.

[0012] Furthermore, a high-pressure water gun storage box is installed above the corridor window. The high-pressure water gun storage box has openable swing doors on both sides, facing the fire exit and escape route respectively, so that high-pressure water guns can be easily retrieved for fire extinguishing in the event of a fire inside or outside the building, and the retrieval of the gun for fire extinguishing and personnel escape do not interfere with each other.

[0013] Compared with the prior art, the fire escape passage device for high-rise buildings with external fireproof and internal heat insulation provided by the present invention has the following beneficial effects:

[0014] (1) This device, through the closed structure design of the escape passage and the setting of the fireproof sealing door of the second escape door, can effectively block the open flame and toxic smoke generated by the fire from entering the interior of the escape passage, and achieve external fireproof and smoke isolation; at the same time, the escape passage can adopt an internal heat insulation structure design, combined with fireproof sealing technology, which can effectively isolate the external high temperature, reduce the internal temperature of the passage, provide a safe escape environment for the escapers, avoid the escapers being burned by high temperature, and solve the problem of poor fireproof and heat insulation effect of existing escape devices.

[0015] (2) The device connects the building’s original fire escape route through the elevator tower and the corresponding set of escape devices on each floor. People can quickly reach the corridor window through the fire escape route and enter the escape route by opening the first escape door. No complicated operation is required, which is suitable for all kinds of people such as the elderly, the weak, the sick, the disabled, and pregnant women. At the same time, the emergency lights in the escape route can work normally without external power supply, ensuring that the escape route is fully illuminated without blind spots and avoiding escape delays caused by obstructed vision.

[0016] (3) The solar panels installed on the outside of the escape device are connected to the emergency lights. They do not need to rely on the building’s regular power or backup power. Even if the fire causes a complete power outage in the building, the solar panels can directly power the emergency lights, ensuring the lighting needs in the escape route. This solves the problem of existing escape devices relying on external power and having poor power supply reliability. At the same time, the steel frame is made of high-temperature resistant steel, which ensures the stability of the escape route under high-temperature conditions in a fire and prevents structural collapse.

[0017] (4) The overall structure of the device is simple. The elevator tower is set on one side of the building. The escape device is fixed between the elevator tower and the building wall by steel brackets. There is no need to carry out large-scale renovation of the original structure of the building. The installation is convenient and the cost is low. Moreover, the division of labor of each component is clear. The setting of the first escape door and the second escape door not only ensures the escape efficiency, but also achieves smoke and dust blocking, further improving the safety and reliability of the escape process. It can be widely used in various high-rise residential buildings, office buildings and other buildings.

[0018] (5) This device makes full use of the building’s existing fire escape routes, eliminating the need for additional dedicated evacuation routes, which effectively reduces the construction cost of the device. At the same time, it leverages the advantages of fire escape routes, which have no open flames and little smoke in the early stages of a fire, to provide a safe initial evacuation route for escapees and further improve the success rate of escape.

[0019] (6) A two-way openable high-pressure water gun storage box is added above the corridor window (or corridor door) so that the gun can be retrieved from the inside / outside of the building in the early stage of the fire. The retrieval of the gun and the personnel evacuation channel are independent of each other, which helps to improve the initial fire extinguishing capability while ensuring the escape efficiency and further reducing the risk of crowding and trampling.

[0029] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] As attached Figure 1 To be continued Figure 6As shown:

[0031] An externally fireproof and internally insulated high-rise building fire escape route system includes an elevator tower 1, multiple escape devices 2, and the building's existing fire escape route 3. The elevator tower 1 is located on one side of the high-rise building, allowing evacuees to descend to the ground for escape. The elevator tower 1 contains only one elevator capable of accommodating multiple people simultaneously, with no other redundant designs to maximize escape efficiency. The elevator is a fast-descent type, with increased ascent and descent rates compared to conventional elevators. Multiple escape devices 2 are correspondingly installed between each floor's corridor and the elevator tower 1, connecting the fire escape route 3 and the elevator tower 1. Each floor of the fire escape route 3 has corresponding escape devices. The device 2 is equipped with a stairwell window 4, which is correspondingly set with the escape device 2, allowing people to enter the escape device 2 from the fire escape 3 and then escape through the elevator tower 1. The escape device 2 includes an escape passage 21, and a first escape door 25 is provided at one end of the escape passage 21 near the stairwell window 4. The first escape door 25 is aligned with the stairwell window 4. After opening the stairwell window 4, people can open the first escape door 25 to enter the escape passage 21. The stairwell window 4 needs to be set as an openable type, or modified into a stairwell door structure that facilitates passage. The front end of the escape passage 21 is made of tempered glass to meet the light transmission requirements of the stairwell window 4.

[0032] In this embodiment, when the corridor window 4 is converted into a corridor door, a high-pressure water gun storage box 5 can also be installed above the corridor window 4 (or corridor door). The storage box has swing doors on both sides, with one swing door facing the fire escape 3 and the other swing door facing the escape route 21. In the event of a fire inside or outside the building, the swing door can be opened on the corresponding side to retrieve the high-pressure water gun for initial fire extinguishing. The process of retrieving the gun for fire extinguishing is independent of the personnel passage through the escape route, avoiding cross-interference.

[0033] In this embodiment, the escape device 2 also includes a steel support 22, which is fixedly connected between the elevator tower 1 and the wall of the high-rise building to support the fixed escape passage 21. The specific number and distribution of the steel supports 22 are set according to the specific load-bearing requirements, such as the approximate maximum number of staff on each floor and the maximum number of people that may be on each floor when the escape passage 21 is in use. The escape passage 21 is a closed passage structure with both ends connected. One end is connected to the entrance of the elevator tower 1, and the other end is set corresponding to the corridor window 4.

[0034] In this embodiment, a second escape door 26 is provided in the middle section of the escape passage 21. The second escape door 26 can be opened and closed. The purpose of setting the second escape door 26 is that when a large number of people escape through the escape device 2, smoke and dust will inevitably enter the escape device 2. At this time, the second escape door 26 can block the smoke and dust, so that the people escaping have a safe environment and time to wait for the elevator of the elevator tower 1.

[0035] In this embodiment, a solar panel 23 is fixedly installed on the outside of the escape passage 21, and an emergency light 24 is provided inside the escape passage 21. The solar panel 23 is electrically connected to the emergency light 24 and is used to supply power to the emergency light 24 when the building's power is interrupted, so as to realize the lighting in the escape passage 21 and avoid the problem that the escape device 2 cannot be lit when the power in the building is interrupted during a fire.

[0036] In this embodiment, the first escape door 25 adopts a push-pull or swing-open structure, and the first escape door 25 is provided with a handle that facilitates quick opening by escaping personnel. The connection between the first escape door 25 and the escape passage 21 is provided with a sealing strip to enhance the sealing performance and reduce the entry of smoke and dust.

[0037] In this embodiment, the elevator installed in the elevator tower 1 is a fireproof elevator. The elevator's operating power system uses an independent backup power supply to ensure that the elevator can operate normally in the event of a fire. In addition, the elevator is equipped with smoke sensors and emergency ventilation devices to further ensure the safety of people escaping.

[0038] Working principle: The elevator tower 1 is built on one side of the high-rise building, and multiple escape devices 2 are built between the elevator tower 1 and the corridor on each floor of the building. When a fire occurs, people can enter the building through the fire escape 3, enter the escape device 2 through the corridor window 4 of the fire escape 3, and then complete the escape through the elevator tower 1.

[0039] Meanwhile, when it is necessary to carry out on-site fire extinguishing in the initial stage of a fire, high-pressure water guns can be retrieved from the high-pressure water gun storage box 5 above the corridor window 4 (or corridor door). If the fire is inside the building, the swing door on the side of the fire escape 3 can be opened to retrieve the gun for fire extinguishing. If the fire is outside the building, the swing door on the side of the escape passage 21 can be opened to retrieve the gun for fire extinguishing, thereby achieving the separation of escape and fire extinguishing.

[0040] Since each floor is equipped with a corresponding escape device 2, people can enter their respective escape passages 21 according to their floors and descend through the elevator tower 1, which can significantly reduce the accumulation of people in the stairwell and reduce the risk of crowding and trampling.

[0041] When a fire occurs, the fire escape 3, which is used in accordance with regulations, will not produce open flames or a large amount of smoke in a short period of time. Therefore, people escaping from each floor can reach the corridor window 4 where the corresponding escape device 2 is located through the fire escape 3. By opening the corridor window 4, they can see the first escape door 25 on the escape device 2. Opening the first escape door 25 allows them to enter the escape device 2. At this point, they only need to walk forward to reach the door of the elevator tower 1. They can then use the elevator in the elevator tower 1 to reach the ground, just like using a regular elevator, thus completing the escape.

[0042] Each escape device 2 is equipped with a solar panel 23 on its outer side. In the event of a fire, the solar panel 23 can directly power the emergency lights 24 inside the escape device 2, providing illumination and preventing the building from being without lighting due to power outages during a fire. Furthermore, a second escape door 26 is installed in the middle section of the escape device 2. The purpose of the second escape door 26 is to block smoke and dust from entering the escape device 2 when a large number of people are escaping through it, giving them a safe environment and time to wait for the elevator in the elevator tower 1.

[0043] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
