Description

Technical Field

[0001] This utility model relates to the field of vacuum-formed door panel technology, specifically a fire-resistant and heat-insulating door body. Background Technology

[0002] In the field of building safety, fire doors, as important passive fire protection facilities, play a crucial role in effectively blocking the spread of fire and smoke for a certain period of time, thus buying precious time for personnel evacuation and fire rescue.

[0003] Traditional fire doors typically use single or composite insulation materials (such as rock wool, aluminum silicate wool, etc.) to fill the door core, relying on the material's own insulation properties to achieve fire resistance. However, in practical applications, the fire resistance of such structures depends entirely on the physical properties of the insulation material and the thickness of the filling. When exposed to prolonged or unexpectedly high-temperature fires, the material gradually carbonizes and fails, causing the temperature on the unexposed side of the door to rise sharply, thus losing its insulation function. Moreover, the heavy filling material makes the door too heavy, placing higher load-bearing requirements on the door frame, hinges, and other hardware, and increasing the burden of daily use. Although existing technologies have attempted to introduce active cooling mechanisms such as water cooling into door designs, these often suffer from problems such as system complexity, low integration, and loose integration with the main door structure. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a fire-resistant and heat-insulating door. By embedding a cooling water tank within the main body of the door panel and linking its interlayer space with the fire water pipe, passive fire prevention is transformed into active fire prevention. In the event of a fire, water can be rapidly injected and fill the entire interlayer of the door panel. Through the large amount of heat absorption and vaporization of the water, heat is efficiently carried away, greatly improving the fire resistance and heat insulation performance and duration of the door panel under extreme high temperatures. This overcomes the defects of traditional heat insulation materials that are prone to failure. The main body of the door panel is a multi-layer composite structure consisting of a base plate, a heat insulation board, a sound insulation board, and an outer layer. Under normal conditions, it can provide excellent heat insulation and sound insulation effects, meeting the daily use and energy-saving and noise reduction needs of the door panel and achieving functional integration. By setting up a reinforced connecting frame and a reinforced outer frame, the overall structural rigidity and stability of the door panel are enhanced, ensuring that the door panel is not easily twisted or deformed in the high-temperature environment of a fire, and providing structural protection for the reliable operation of the internal cooling system.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a fire-resistant and heat-insulating door body, comprising a door panel body, wherein the door panel body comprises a base plate, a heat insulation board, a sound insulation board and an outer layer; A reinforcing connecting frame is connected to the main body of the door panel, and a reinforcing outer frame is connected to the outside of the reinforcing connecting frame; The main body of the door panel is equipped with a cooling water tank. A flexible hose is connected to the cooling water tank. The flexible hose passes through the main body of the door panel and is connected to an external pipe. The external pipe is connected to a fire water pipe and is linked to the fire alarm system. The cooling water tank has a hollow design and is connected to the interlayer space inside the main body of the door panel. After a fire occurs, the external pipe injects water into the cooling water tank and fills the gaps in each interlayer of the door body to achieve fire insulation.

[0006] Preferably, the reinforcing connecting frame is provided with multiple sets of positioning pins, which pass through the door panel body and are connected to the reinforcing connecting frame.

[0007] Preferably, the reinforcing connection frame is provided with a snap-fit ​​assembly for reinforcing the connection between the external pipe and the flexible hose. The snap-fit ​​assembly includes a fixing plate disposed on the reinforcing outer frame, a screw threadedly connected to the fixing plate, and a clamping block rotatably connected to the screw.

[0008] Preferably, the clamping block is slidably connected to the reinforced outer frame.

[0009] Preferably, the external pipe is equipped with a control valve and connected to the fire control system. After the smoke detector of the fire control system detects the fire and alarms, the control valve is opened by controlling the fire control system.

[0010] Preferably, the lead screw is provided with a rotating handle.

[0011] This utility model discloses a fire-resistant and heat-insulating door, which has the following beneficial effects: This fire-resistant and heat-insulating door transforms passive fire prevention into active fire protection by embedding a cooling water tank within the main body of the door panel and linking its interlayer space with the fire water pipes. In the event of a fire, water can quickly inject and fill the entire interlayer of the door. Through the large amount of heat absorption and vaporization of the water, heat is efficiently carried away, greatly improving the fire resistance and heat insulation performance and duration of the door under extreme high temperatures.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0017] This utility model discloses a fire-resistant and heat-insulating door, according to the attached... Figure 1 To be continued Figure 7As shown, the door panel includes a main body 1, which is composed of a base plate 11, a heat insulation board 12, a sound insulation board 13, and an exterior layer 14. The base plate 11 is the core support structure of the door, the heat insulation board 12 and the sound insulation board 13 provide heat insulation and sound insulation functions, respectively, and the exterior layer 14 is the external decorative layer of the door. A reinforcing connecting frame 2 is connected to the main body 1, and a reinforcing outer frame 3 is connected to the outside of the reinforcing connecting frame 2 to enhance the overall structural strength and stability of the door. A cooling water tank 4 is provided inside the main body 1, and a flexible hose 41 is connected to the cooling water tank 4. The flexible hose 41 passes through the main body 1 and is connected to an external pipe 5. The external pipe 5 is connected to a fire water pipe and is linked to a fire alarm system. The cooling water tank 4 has a hollowed-out design and is connected to the interlayer space inside the main body 1. After a fire occurs, the external pipe 5 injects water into the cooling water tank 4 and fills the gaps in the interlayer of the door to achieve fire insulation.

[0018] According to the appendix Figure 2 and attached Figure 4 As shown, the reinforcing connecting frame 2 is equipped with multiple sets of positioning pins 21. The positioning pins 21 pass through the door panel body 1 and are connected to the reinforcing connecting frame 2. The positioning pins 21 ensure the precise fixation of the reinforcing connecting frame 2 to the door panel body 1 and prevent displacement. Furthermore, the positioning pins 21 are made of high-strength steel to withstand the thermal stress under fire conditions.

[0019] According to the appendix Figure 4 Appendix Figure 5 and attached Figure 6 As shown, the reinforcing connecting frame 2 is equipped with a clamping assembly 6 for reinforcing the connection between the external pipe 5 and the hose 41. The clamping assembly 6 includes a fixing plate 61 mounted on the reinforcing outer frame 3, a screw rod 62 threaded onto the fixing plate 61, and a clamping block 63 rotatably connected to the screw rod 62. Furthermore, rotating the screw rod 62 can drive the clamping block 63 to move, thereby pressing the connection between the external pipe 5 and the hose 41 to prevent leakage.

[0020] According to the appendix Figure 5 As shown, the clamping block 63 is slidably connected to the reinforced outer frame 3 to ensure that the clamping block 63 remains stable during movement and avoids tilting.

[0021] According to the appendix Figure 6 As shown, an external pipe 5 is equipped with a control valve 51 and is connected to the fire control system. After the smoke detector of the fire control system detects a fire and sounds an alarm, the control valve 51 is opened by controlling the fire control system. Furthermore, the control valve 51 is a solenoid valve, which responds quickly to ensure timely water injection in the early stages of a fire.

[0022] According to the appendix Figure 5 As shown, the lead screw 62 is equipped with a rotating handle for easy manual adjustment of the tightness of the clamping block 63, improving the convenience of installation and maintenance. Furthermore, the surface of the rotating handle is provided with anti-slip texture to enhance the operating feel.

[0023] According to the appendix Figure 1 To be continued Figure 7 As shown, the interlayer space of the door panel body 1 is formed by the gap between the base plate 11, the heat insulation board 12, the sound insulation board 13 and the outer layer 14. The hollow design of the cooling water tank 4 allows the water flow to spread quickly to the entire interlayer and fill it evenly, thereby effectively reducing the door temperature and preventing heat conduction in case of fire.

[0024] According to the appendix Figure 2 To be continued Figure 7 As shown, the cooling water tank 4 is made of high-temperature resistant material and has multiple diversion channels inside. It is connected to the external pipe 5 through the hose 41. The external pipe 5 is connected to the building's fire water pipe network to ensure sufficient water supply. During the water injection process, the water flows into the interlayer through the perforation of the cooling water tank 4, which not only cools the door but also forms a water film to enhance the heat insulation effect.

[0025] According to the appendix Figure 1 To be continued Figure 7 As shown, it is particularly important to emphasize that the reinforced outer frame 3 and the main body of the door panel 1 form an integral frame through the reinforced connecting frame 2, which improves the door's resistance to deformation and maintains structural integrity in the event of a fire. At the same time, the design of the snap-fit ​​component 6 ensures the safety of the pipe connection and avoids leakage due to vibration or thermal expansion.

[0026] According to the appendix Figure 1 To be continued Figure 7 As shown, it is particularly important to emphasize that the fire control system is linked to the door. When the smoke alarm is triggered, the control valve 51 opens automatically, and water flows through the external pipe 5 and the hose 41 into the cooling water tank 4, quickly filling the door interlayer. The entire process requires no manual intervention, achieving rapid response and passive fire protection.

[0027] Example 1: This example uses a conventional fire as an example, combined with the attached... Figure 1 To be continued Figure 7 Detailed explanation of the workflow: The workflow is as follows: When a fire occurs inside the building, the smoke detector detects the smoke and sends a signal to the fire control system. The fire control system automatically opens the control valve 51 on the external pipe 5, and the water in the fire water pipe flows through the external pipe 5 and the hose 41 into the cooling water tank 4 inside the door panel body 1. The water overflows from the hollowed-out part of the cooling water tank 4 and fills the interlayer space of the door panel body 1, including the gap between the base plate 11, the heat insulation board 12, the sound insulation board 13 and the outer layer 14. The water absorbs heat and evaporates in the interlayer, effectively reducing the door temperature and preventing the fire from spreading. At the same time, the heat insulation board 12 and the sound insulation board 13 enhance the heat insulation performance with the help of water. Throughout the process, the reinforced connecting frame 2 and the reinforced outer frame 3 ensure the stability of the door structure, and the snap-fit ​​component 6 prevents the pipe connection from loosening.

[0028] Example 2: This example uses a high-temperature environment as an example, combined with the attached... Figure 1 To be continued Figure 7 Detailed explanation of the workflow: The workflow is as follows: Under high-temperature fire conditions, the door is exposed to extreme heat. The outer layer 14 is heated first, but the internal cooling water tank 4 is quickly filled with water, and the water flows through the interlayer to form a cooling cycle. The control valve 51 is continuously open to ensure a continuous water flow, and the internal temperature of the door is maintained within a safe range. At the same time, the sound insulation board 13 and the heat insulation board 12 expand under the action of water, further sealing the gaps in the interlayer and strengthening the fire barrier. The outer frame 3 and the positioning pin 21 are reinforced to resist thermal stress and prevent the door from deforming. The snap-fit ​​assembly 6 keeps the pipe connection tight through the screw 62 and the clamping block 63 to prevent leakage caused by high-pressure water flow.
