Description

Technical Field

[0001] The present invention relates to the technical field of fire doors, and particularly to a fire door that combines daylighting and guiding escape. Background Art

[0002] A fire door refers to a door that can meet the requirements of fire resistance stability, integrity, and heat insulation within a certain period of time. It is a fire separation with a certain fire resistance provided in fire compartments, evacuation stairwells, vertical shafts, etc.

[0003] Most existing fire doors are steel normally closed fire doors. In the normally closed state, daylighting cannot be achieved through the location of the fire door in the separated area. On the other hand, during a fire, salt spray fills the air, obscuring the line of sight. Escapees often miss the opportunity to escape because they cannot quickly locate the position of the fire door due to low visibility. Summary of the Invention

[0004] The technical problem to be solved by the present invention is: to provide a fire door that combines daylighting and guiding escape, and solve the problems that existing normally closed steel fire doors cannot provide daylighting in the separated area and escapees cannot quickly locate the position of the fire door at the fire scene with salt spray filling the air.

[0005] To solve the above technical problem, the technical solution adopted by the present invention is:

[0006] A fire door that combines daylighting and guiding escape, including a door leaf main body and a door leaf frame;

[0007] The shape of the door leaf main body is a cuboid, the material of the door leaf main body is fireproof glass, the door leaf main body is provided with a receiving cavity, and a liquid inlet is provided at the upper part of the receiving cavity; light storage type material layers are respectively provided at the upper, lower, left, and right sides of the receiving cavity;

[0008] The door leaf frame is connected to the upper, lower, left, and right sides of the door leaf main body. The door leaf frame includes an upper frame. A liquid storage tank is provided in the upper frame, and a high-boiling-point flame retardant liquid and high-reflection microparticles are stored in the liquid storage tank. A liquid discharge port is provided at the position of the receiving cavity corresponding to the liquid inlet. A baffle made of a heat-deformable material is connected between the liquid inlet and the liquid discharge port. The material of the upper frame is a heat-conducting metal.

[0009] Further, in the above fire door structure that combines daylighting and guiding escape, the heat-deformable material is specifically polypropylene material.

[0010] Further, in the above fire door structure that combines daylighting and guiding escape, the thickness of the heat-deformable material is less than 1 mm.

[0011] Further, in the above fire door structure that combines daylighting and guiding escape, a sealing ring is provided at the liquid inlet, and a sealing ring is provided at the liquid discharge port.

[0012] Further, in the above fire door structure with both daylighting and escape guiding functions, the high-boiling-point flame retardant liquid is selected from triethyl phosphate.

[0013] Further, in the above fire door structure with both daylighting and escape guiding functions, the high-reflection particles are specifically nano-silica particles.

[0014] Further, in the above fire door structure with both daylighting and escape guiding functions, the material of the light-storing material layer is luminescent ceramics.

[0015] Further, in the above fire door structure with both daylighting and escape guiding functions, a slot for inserting and removing a baffle is provided between the liquid inlet and the liquid outlet of the upper frame. One section of the baffle blocks between the liquid inlet and the liquid outlet, and the other section of the baffle extends outside the upper frame. The surface of the part of the baffle extending outside the upper frame is provided with a light-storing material layer.

[0016] The beneficial effects of the present invention are as follows: When used as a fire door for corridor partition in daily life, it is in a normally closed state. External light can be transmitted through the fireproof glass material of the door leaf main body to one side of the partition, so that one side of the partition obtains sufficient daylighting. When a fire occurs on one side of the partition, the temperature rises sharply, causing the baffle to soften due to heat, thus losing the sealing partition between the liquid outlet and the liquid inlet. The high-boiling-point flame retardant liquid and the high-reflection particles in the liquid storage tank enter the accommodation cavity of the door leaf main body through the liquid inlet, and the high-reflection particles are dispersed in the accommodation cavity. Under the luminescent effect of the light-storing material layer, the high-reflection particles reflect the light, making the entire door leaf main body present a luminescent form. The large-area luminescent area enables the escape personnel to quickly locate the position of the fire door through the smoke and escape smoothly. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] To describe in detail the technical content, achieved purpose and effect of the present invention, the following is described in conjunction with the implementation mode and with reference to the drawings.

[0029] Please refer to Figures 1 to 8 , the specific implementation mode of the present invention relates to a fire door with both daylighting and escape guiding functions, including a door leaf main body 1 and a door leaf frame 2;

[0030] The shape of the door leaf main body is a cuboid, the material of the door leaf main body 1 is fireproof glass, the door leaf main body 1 is provided with an accommodating cavity 11, and a liquid inlet 12 is arranged at the upper part of the accommodating cavity 11; phosphorescent material layers 13 are respectively arranged at the upper, lower, left and right sides of the accommodating cavity 11;

[0031] The door leaf frame 2 is connected to the upper, lower, left and right sides of the door leaf main body 1. The door leaf frame 2 includes an upper frame 21. A liquid storage tank 22 is arranged inside the upper frame 21. A high-boiling-point flame retardant liquid and high-reflection particles are stored in the liquid storage tank 22. A drain port 23 is arranged at the position of the accommodating cavity 11 relative to the liquid inlet 12. A flap 24 made of a heat-deformable material is connected between the liquid inlet 12 and the drain port 23. The material of the upper frame 21 is a heat-conducting metal, preferably copper.

[0032] In the above embodiments, when used as a fire door for corridor partition in daily life, it is in a normally closed state. External light can be transmitted through the fireproof glass material of the door leaf main body 1 to one side of the partition, enabling sufficient daylighting on one side of the partition. When a fire occurs on one side of the partition, the temperature rises sharply, causing the baffle 24 to soften due to heat, thereby losing the sealing partition between the liquid discharge port 23 and the liquid inlet 12. As a result, the high-boiling-point flame retardant liquid and high-reflection particles in the liquid storage tank 22 enter the accommodation cavity 11 of the door leaf main body 1 through the liquid inlet 12, and the high-reflection particles are dispersed in the accommodation cavity 11. Under the luminescent effect of the photoluminescent material layer 13, the high-reflection particles reflect the light, making the entire door leaf main body 1 present a luminescent form. The large-area luminescent area enables the escaping personnel to quickly locate the position of the fire door through the smoke and escape smoothly.

[0033] Preferably, the heat-deformable material is specifically a polypropylene material. The heat distortion temperature of the polypropylene material is 70 - 80°C. When a fire occurs on one side of the corridor, the relatively enclosed environment causes the ambient temperature to rise sharply. Since the material of the upper frame 21 is a high thermal conductivity material, the upper frame 21 will quickly heat up to above 80°C, higher than the ambient temperature, and heat the polypropylene material baffle 24 through heat transfer, causing the baffle 24 to soften.

[0034] Preferably, the thickness of the heat-deformable material is less than 1 mm, preferably 0.5 mm. The thickness of the heat-deformable material should not be too thick, otherwise it is easy to cause the time for it to soften due to heat to be too long, resulting in the situation that when a fire occurs, the high-reflection particles and high-boiling-point flame retardant liquid cannot flow into the accommodation cavity 11 of the door leaf main body 1 in time because the heat-deformable material does not melt and deform in time. Theoretically, the thinner the heat-deformable material, the better, but a certain thickness is required to ensure its structural strength before melting and deforming, and to prevent the baffle 24 from directly losing the barrier to the liquid inlet 12 and the liquid discharge port 23 due to vibration.

[0035] Preferably, a sealing ring is provided at the liquid inlet 12, and a sealing ring is provided at the liquid discharge port 23. In the state where no fire occurs, the baffle 24 is blocked between the liquid discharge port 23 and the liquid inlet 12 through the sealing rings connected up and down, maintaining the sealing property and preventing the liquid in the liquid storage cavity from entering the accommodation cavity 11.

[0036] Preferably, the high-boiling-point flame retardant liquid is selected from triethyl phosphate.

[0037] Preferably, the high-reflection particles are specifically nano-silica particles.

[0038] Preferably, the material of the photoluminescent material layer 13 is luminescent ceramic.

[0039] Preferably, a slot for inserting and removing a baffle 24 is provided between the liquid inlet 12 and the liquid outlet 23 of the upper frame 21. One section of the baffle 24 blocks between the liquid inlet 12 and the liquid outlet 23, and the other section of the baffle 24 extends outside the upper frame 21. A photoluminescent material layer 13 is provided on the surface of the part of the baffle 24 that extends outside the upper frame 21.

[0040] In the above structure, one section of the baffle 24 blocks between the liquid inlet 12 and the liquid outlet 23, and the other section of the baffle 24 extends outside the upper frame 21. On the one hand, it enables the baffle 24 to contact the upper frame 21 made of heat-conducting metal material, so that the high temperature accumulated in the upper frame 21 can be quickly transferred to the baffle 24, enabling the baffle 24 to melt and deform more sensitively during a fire, and allowing the high-reflection particles and the high-boiling-point flame retardant liquid to quickly flow into the accommodation cavity 11. On the other hand, when the fire breaks out in the initial stage and the fire has not spread to the location of the fire door, the baffle 24 can also be pulled out manually to artificially make the high-reflection particles and the high-boiling-point flame retardant liquid quickly flow into the accommodation cavity 11, facilitating the positioning of the subsequent escaping personnel. A photoluminescent material layer 13 is provided on the surface of the part of the baffle 24 that extends outside the upper frame 21, facilitating the escaping personnel to quickly locate the position of the baffle 24.

[0041] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in the relevant technical fields, shall be equally included in the patent protection scope of the present invention.
