Description

Technical Field

[0001] This utility model relates to the field of fire emergency door technology, and in particular to a double-sided insulated fire emergency door. Background Technology

[0002] Fire emergency doors are a special type of fire door. They are doors that can meet the requirements of fire resistance stability, door integrity, and heat insulation for a certain period of time. They are mostly located in fire-resistant compartments, evacuation staircases, shafts, and other fire isolation zones. They are fire-resistant partitions with strong fire resistance. Their main function is to prevent the spread of fire and smoke. They can stop the spread of fire for a certain period of time and ensure the evacuation of personnel.

[0003] Most existing insulated fireproof emergency doors have an integrated door panel structure. During assembly, a magnesium oxide insulation board is installed inside the door. However, the location of a fire can vary, and the direction of its spread can also change. Therefore, most emergency doors are exposed to more heat on one side. Since integrated insulated fireproof emergency doors are mostly fixed after being closed, it takes a lot of time to completely destroy the insulated fireproof emergency door when entering the fire scene from the side furthest from the fire, which reduces the effectiveness of the insulated fireproof emergency door.

[0004] Therefore, in view of the problem that most existing insulated fire emergency doors are subject to more heat on one side during use, and that most integrated insulated fire emergency doors are fixed after being closed, it takes a lot of time to completely destroy the insulated fire emergency door when entering the fire scene from the side away from the fire, which leads to a decrease in the effectiveness of the insulated fire emergency door, a double-sided insulated fire emergency door can be designed. Summary of the Invention

[0005] To overcome the problem that existing insulated fireproof emergency doors are mostly exposed to more heat on one side during use, and that integrated insulated fireproof emergency doors are mostly fixed after being closed, it takes a long time to completely destroy the insulated fireproof emergency door when entering the fire scene from the side away from the fire, thus reducing the effectiveness of the insulated fireproof emergency door.

[0007] Preferably, the main body of the door frame is installed at the partition position by the outer frame, and the main body of the door frame is fixed by the support block and the fixing rod to block the direction of fire spread. At the same time, the first magnesium oxide heat insulation board is installed by the mounting frame and the connecting rod to provide heat insulation and fire protection, and the rotating plate is used to provide heat insulation and fire protection on both sides of the emergency door.

[0008] Preferably, the mounting frame has a mounting groove on its outer side, a limiting groove on its outer side, a sliding groove on its inner side, and a positioning bolt slidably connected to the inner side of the sliding groove.

[0009] Preferably, a connecting block is fixed to the inner side of the rotating plate, a second magnesium oxide heat insulation plate is installed on the outer side of the connecting block, and a first connecting frame is fixed to one end of the rotating plate.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5 This utility model provides an embodiment of a double-sided insulated fireproof emergency door, including a door frame body 1; it also includes a mounting frame 6 and a rotating plate 14. An outer frame 2 is fixedly connected to the outer side of the door frame body 1, and a mounting bracket 3 for supporting an inorganic intumescent flame retardant is slidably connected to the inner side of the outer frame 2. Support blocks 4 are slidably connected to the upper and lower ends of the outer frame 2, and fixing rods 5 are fixedly connected to the outer side of the support blocks 4. The mounting frame 6 is fixedly connected to the inner side of the door frame body 1, and positioning holes 8 are provided at the upper and lower ends of the mounting frame 6. The inner side of the mounting frame 6 is provided with... There is a first magnesium oxide heat insulation board 12 for heat insulation and fire prevention. The upper and lower ends of the first magnesium oxide heat insulation board 12 are equipped with connecting rods 13. The front and rear ends of the door frame body 1 are equipped with rotating plates 14. The door frame body 1 is installed in the partition position through the outer frame 2, and the door frame body 1 is fixed by the support block 4 and the fixing rod 5 to block the direction of fire spread. At the same time, the first magnesium oxide heat insulation board 12 is installed through the mounting frame 6 and the connecting rod 13, thereby providing heat insulation and fire prevention. The rotating plate 14 is used to provide heat insulation and fire prevention on both sides of the emergency door at the same time.

[0024] Please see Figures 2-4In this embodiment, an installation groove 7 is provided on the outer side of the mounting frame 6, a limiting groove 9 is provided on the outer side of the installation groove 7, and a sliding groove 10 is provided on the inner side of the limiting groove 9. A positioning bolt 11 is slidably connected to the inner side of the sliding groove 10. The inorganic intumescent flame retardant is placed through the installation groove 7 to improve the fireproof effect during a fire and fill gaps. The limiting groove 9 facilitates the entry and exit of the positioning bolt 11 from the sliding groove 10, and the sliding groove 10 facilitates the up and down movement of the positioning bolt 11. A docking block 15 is fixedly connected to the inner side of the rotating plate 14. A second magnesium oxide heat insulation plate 16 is installed on the outside of the rotating plate 14. A first connecting frame 17 is fixedly connected to one end of the rotating plate 14. The second magnesium oxide heat insulation plate 16 is installed through the connecting block 15, thereby improving the fireproof effect of the two rotating plates 14 and thus improving the fireproof effect of both sides of the emergency door. A threaded rod 18 is rotatably connected to the front end of the first connecting frame 17. A connecting block 19 is threadedly connected to the outside of the threaded rod 18. The connecting block 19 is slidably connected to the first connecting frame 17. The threaded rod 18 drives the connecting block 19 to move back and forth.

[0025] Please see Figures 4-5 In this embodiment, a support rod 20 is rotatably connected to the outer side of the connecting block 19, and a moving block 21 is rotatably connected to the outer side of the support rod 20. A first positioning rod 22 is fixedly connected to the outer side of the moving block 21. The moving block 21 and the first positioning rod 22 are slidably connected to the first connecting frame 17. The connecting block 19 drives the support rod 20 and the moving block 21 to move, thereby driving the first positioning rod 22 to engage with the positioning hole 8, thus facilitating the rotation plate 14 to rotate and unfold around the first positioning rod 22. A second connecting frame 23 is fixedly connected to the other end of the rotating plate 14. The inner side of the second connecting frame 23 is provided with a moving groove 24. The rotating plate 14 is conveniently fixed through the second connecting frame 23 and the moving groove 24. The inner side of the moving groove 24 is slidably connected to a slider 25. The outer side of the slider 25 is fixedly connected to a second positioning rod 26. The slider 25 is threadedly connected to the positioning bolt 11. The first positioning rod 22 and the second positioning rod 26 are both slidably connected to the door frame body 1 through the positioning hole 8. The slider 25 and the second positioning rod 26 are moved through the moving groove 24 and the positioning bolt 11, so that the rotating plate 14 can rotate around the second positioning rod 26.

[0026] In use, firstly, the door frame body 1 is installed at the partition position by the outer frame 2 and can be opened and closed normally. Then, in the event of a fire, the inorganic expandable flame retardant inside the mounting bracket 3 expands and pushes the support block 4 and the fixing rod 5 to fix the door frame body 1, thereby blocking the direction of fire spread. Then, the inorganic expandable flame retardant placed in the mounting groove 7 fills the gaps to improve the fire resistance effect during a fire. Finally, the first magnesium oxide heat insulation board 12 is installed by the mounting frame 6 and the connecting rod 13, and the second magnesium oxide heat insulation board 16 is installed by the connecting block 15, thereby improving the fire resistance effect of the two rotating plates 14, and thus improving the fire resistance effect of both sides of the emergency door.

[0027] During maintenance, firstly, the positioning bolt 11 is easily moved into and away from the slide groove 10 via the limiting groove 9, and the slide groove 10 facilitates the up and down movement of the positioning bolt 11. When the fire-facing side is opened, the threaded rod 18 drives the connecting block 19 to move back and forth, thereby driving the support rod 20 and the moving block 21 to move via the connecting block 19, which in turn drives the first positioning rod 22 to move, thus disengaging it from the positioning hole 8, so that the fire-facing rotating plate 14 can rotate and unfold around the second positioning rod 26. Next, the connecting rod 13 is broken to disassemble the first magnesium oxide heat insulation plate 12. Then, the positioning bolt 11 is connected to and the slider 25 is moved, thereby driving the second positioning rod 26 to disengage from the positioning hole 8, thus facilitating the rotation of the fire-facing rotating plate 14 around the first positioning rod 22, and thus facilitating the user to pass through the emergency door to maintain the fire scene.

[0028] Through the above steps, the main body 1 of the door frame is installed at the partition position through the outer frame 2, and the first magnesium oxide heat insulation board 12 is installed through the mounting frame 6 and the connecting rod 13. When the emergency door is heated by fire, the inorganic expandable flame retardant in the mounting frame 3 reacts with heat, thereby foaming and expanding to fill the gaps for heat insulation and fire prevention. The rotating plate 14 is used in conjunction with the first magnesium oxide heat insulation board 12 to isolate the fire scene, thereby enabling heat insulation and fire prevention on both sides of the emergency door at the same time, which facilitates fire fighting work by firefighters. This solves the problem that when existing heat-insulated fire-resistant emergency doors are in use, most emergency doors are mostly heated on one side, and most integrated heat-insulated fire-resistant emergency doors are fixed after being closed. When entering the fire scene from the side away from the fire, it takes a lot of time to completely destroy the heat-insulated fire-resistant emergency door, resulting in a decrease in the effectiveness of the heat-insulated fire-resistant emergency door.
