[0037] It should be noted that, refer to Figure 1 A steel-wood heat-insulating, sound-insulating and fire-proof door has the following specific structure: the inner side of the door frame 1 is connected to the door leaf 2 through a fire-proof hinge 3. Specifically, the inner side of the door frame 1 is movably connected to the door leaf 2 through a hinge. The hinge is also called a hinge, which is a mechanical device used to connect objects and make the objects rotate relative to each other. One side of the door frame 1 is connected to one side of the door leaf 2 through a hinge, so that the door leaf 2 rotates along one side of the fire-proof door frame 1.

[0038] In a specific implementation, three fireproof hinges 3 are provided, two fireproof hinges 3 are provided at intervals between the upper portion of the door leaf 2 and the door frame 1 , and one fireproof hinge 3 is provided between the lower portion of the door leaf 2 and the door frame 1 .

[0039] It should be noted that at least one door mirror assembly is provided on the door leaf 2, and the first glass 22 and the second glass 23 of each door mirror assembly are tempered soundproof glass, and the tempered soundproof glass is a double-layer structure, and there is a vacuum layer between the double-layer structure. The explosion-proof heat-absorbing composite layer needs to be a transparent layer so that the internal and external conditions can still be seen through the glass after these layers are set. The heat-resistant layer 271 has excellent high temperature resistance, and the heat-absorbing layer 272 can absorb heat on the glass to improve the heat resistance effect of the door mirror.

[0040] As an example, the heat-resistant layer 271 is made of polyimide material, the heat-absorbing layer 272 is made of polymethyl methacrylate with a laser absorbent added thereto, and the explosion-proof layer 273 is made of polyester film.

[0041] In a specific implementation, referring to Figure 1 The door leaf 2 is provided with three door mirror assemblies from top to bottom. The door frame 1 is made of 2.0 mm cold-rolled galvanized steel sheet. The thickness of the door leaf 2 is 60 mm.

[0042] In a specific implementation, the door frame 1 has a height of 2700 mm and a width of 1500 mm. The door leaf 2 has a height of 2620 mm and a width of 1394 mm.

[0043] In this embodiment, a sound absorbing strip 25 is provided on the inner side of the door mirror frame 21 and in the sealed cavity 24 .

[0044] It should be noted that, refer to Figure 5 Since the sound absorbing strip 25 is disposed on the inner side of the door mirror frame 21 and between the first glass 22 and the second glass 23 , the vibration generated by the noise can be absorbed by the sound absorbing strip 25 .

[0045] In this embodiment, a sound insulation layer 26 is disposed on the surface of the first glass 22 and / or the second glass 23 facing the sealed cavity 24 .

[0046] It should be noted that, refer to Figure 5 The sound insulation layer 26 can effectively absorb the vibration transmitted to the closed cavity 24, thereby effectively reducing noise and improving the sound insulation performance.

[0047] In this embodiment, refer to Figure 5The door leaf 2 includes an inner frame 6, a magnesia perlite fireproof door core board 7, a fireproof board 8, an inner lining steel plate, and a door leaf panel 5.

[0048] It should be noted that the magnesite perlite fireproof door core board 7 is a fireproof door core board composed of magnesium oxide, magnesium chloride, magnesium sulfate, perlite, and a foaming agent. Magnesium oxide, magnesium sulfate, and magnesium chloride have good flame retardant effects, giving the fireproof door core board excellent fireproof performance and stability. In addition, the magnesite perlite fireproof door core board 7 has a lower bulk density and bulk density, and flame-retardant wood is used on its peripheral side, which can reduce the use of the fireproof board 8 and reduce the deadweight of the door leaf 2. At the same time, the magnesite perlite fireproof door core board 7 has high compressive strength and flexural strength, so that the fireproof door core board can meet the fireproof performance while also having good structural strength.

[0049] In a specific implementation, the inner lining steel plate is made of a 1.0 mm cold-rolled galvanized steel plate, the door panel 5 is made of a 5 mm flame-retardant density board, and the inner frame 6 is made of a 1.5 mm cold-rolled galvanized steel plate.

[0050] In this embodiment, an exoskeleton is provided outside the door leaf 2, and a fireproof expansion seal 9 is provided between the exoskeleton and the position of the door frame 1 located outside the door.

[0051] As an example, the fireproof expansion seal 9 surrounds the inner side of the door frame 1. When a fire occurs, the fireproof expansion seal 9 expands due to heat, and the gas generated by the fire is isolated at the gap between the door frame 1 and the door leaf 2, preventing toxic gas from entering the room.

[0052] In a specific implementation, the inner frame 6 is 38 mm long and 20 mm high; the outer frame is 48 mm long and 20 mm high.

[0053] In this embodiment, an anti-theft structure 10 is provided between the outer frame and the door frame 1. The anti-theft structure 10 is an anti-pry pin, and the addition of the anti-theft structure 10 enhances the anti-impact and anti-theft capabilities of the door.

[0054] In this embodiment, the outer surface of the door leaf 2 is evenly coated with a flame retardant paint layer.

[0055] It should be noted that the flame retardant paint layer can form a carbonized layer when the material encounters fire. This carbonized layer can isolate the heat source and slow down the spread of the fire, thereby providing more time for people to evacuate.

[0056] In this embodiment, the outer surfaces of the first glass 22 and the second glass 23 are both provided with textures.

[0057] It should be noted that textures are provided on the glass surfaces of the first glass 22 and the second glass 23 to make the fire door more beautiful.

[0058] In this embodiment, a fireproof lock 4 is provided on the side of the door leaf 2 away from the fireproof hinge 3 .

[0059] In this embodiment, the fireproof lock 4 includes a keyhole and a handle, and the handle is provided with a fireproof coating. Providing the fireproof coating on the handle can prevent the handle from being heated or burned by fire, and can open the fireproof door in time when a fire occurs, which can facilitate the timely evacuation of personnel and optimize the role of the fireproof door.
