Description

Technical Field

[0001] The utility model belongs to the technical field of fireproof doors, in particular to a fireproof door with smoke-proof effect for fire-fighting passages. Background Art

[0002] A fire door is a door that meets the requirements of fire resistance, stability, integrity and thermal insulation within a certain period of time. It is a fire-resistant partition with a certain fire resistance installed between fire compartments, evacuation stairwells, vertical shafts, etc. In addition to the functions of ordinary doors, fire doors also have the function of preventing the spread of fire and smoke. They can prevent the spread of fire within a certain period of time and ensure the evacuation of personnel.

[0003] The fire doors for fire escape passages currently on the market have the following problems when used:

[0004] 1. In actual use, traditional fire doors for fire escape passages are usually assembled from door covers and door bodies. However, there is a gap between the door covers and the door bodies, which allows smoke to seep out of the gap, which not only affects the health of the evacuated people, but also has a weak smoke-proof effect when using fire doors;

[0005] 2. Most fire escape passages use fire doors. At the same time, the sealing structure on the side of the fire door is often easily worn out after a long period of back and forth friction, but it is troublesome to repair, so it is inconvenient to replace the sealing structure during use. Utility Model Content

[0008] Preferably, plug plates are embedded on the sides of the first door panel and the second door panel, a sealing strip is connected to the outside of the plug plates, a sealing cover is provided on the outside of the first door panel, a threaded hole is opened on the top of the plug plates, and the internal threads of the threaded holes are connected to fastening bolts.

[0009] Preferably, an arc-shaped groove is provided on the outside of the sleeve frame, a threaded rod is provided inside the arc-shaped groove, and the top of the threaded rod is connected to a blocking block.

[0010] Preferably, a groove is provided inside the sealing frame, and a sealing plate is embedded inside the groove, and the sealing plates are provided in four groups.

[0011] Preferably, circular grooves are provided at the tops of the first door panel and the second door panel, and fastening bolts are embedded inside the circular grooves.

[0012] Preferably, slots are provided on the sides of the first door panel and the second door panel, and the plug-in plate is inserted into the slots.

[0013] The fireproof door with smoke-proof effect for fire passage of the utility model has the following advantages:

[0014] 1. The fire door with smoke-proof effect for the fire passage is provided with a sleeve frame, strip plate, sealing plate, sealing frame and other structures on the outside of the door body, so that the smoke-proof effect of the fire door can be improved. When an accident occurs, after the fire door is closed, the strip plates inside the sleeve frame are moved in sequence, so that the sealing plate inside the sealing frame seals the gap, reducing the flow of smoke to the evacuated personnel, thereby reducing the impact on the personnel's body. Therefore, the smoke-proof effect of the fire door is enhanced during use;

[0015] 2. The fire escape uses a smoke-proof fire door. By providing a plug plate, a sealing strip, a sealing cover, a fastening bolt and other structures on the outside of the door body, it is convenient to replace the worn sealing structure.

[0028] like Figure 1-4 As shown, the fire door with smoke-proof effect for the fire passage of the utility model comprises a door cover 1, the door cover 1 is connected to the first door panel 2 through a rotating shaft, because the door body is provided, it is convenient to connect the door panel to the wall, the door cover 1 is connected to the second door panel 3 through a rotating shaft, the first door panel 2 and the second door panel 3 are fixedly connected to the outer casing 4, the inner part of the casing 4 is inlaid with a strip plate 8, the top of the strip plate 8 is connected to a sealing frame 5, the inner part of the sealing frame 5 is inlaid with a sealing plate 7, the outer part of the strip plate 8 is provided with a threaded rod 10, and the outer part of the threaded rod 10 is threadedly connected to a butterfly nut 12, by providing the casing 4, the strip plate 8, the sealing plate 7, the sealing frame 5 and other structures on the outer part of the door body, when an accident occurs, after the fire door is closed, the sealing plate 7 inside the sealing frame 5 will seal the gap, reduce the smoke flow to the evacuated personnel, so the smoke-proof effect of the fire door is enhanced during use.

[0029] The sides of the first door panel 2 and the second door panel 3 are inlaid with plug plates 16, the outside of the plug plates 16 is connected to a sealing strip 18, a sealing cover 19 is provided on the outside of the first door panel 2, a threaded hole 14 is opened on the top of the plug plates 16, and the internal threads of the threaded holes 14 are connected to fastening bolts 15. By arranging the plug plates 16, the sealing strip 18, the sealing cover 19 and the fastening bolts 15 on the outside of the door body, it is convenient to replace the worn sealing structure and it is relatively simple to operate.

[0030] The outer part of the sleeve frame 4 is provided with an arc groove 9, the inner part of the arc groove 9 is provided with a threaded rod 10, the top of the threaded rod 10 is connected to a blocking block 11, and the installation of the arc groove 9 facilitates the movement of the threaded rod 10 in the arc groove 9 outside the frame.

[0031] A groove 6 is provided inside the sealing frame 5 , and a sealing plate 7 is embedded inside the groove 6 . There are four sets of sealing plates 7 . Due to the groove 6 , it is convenient to embed the sealing plate 7 in the sealing frame 5 .

[0032] A circular groove 13 is formed on the top of the first door panel 2 and the second door panel 3 , and a fastening bolt 15 is embedded in the circular groove 13 . The circular groove 13 makes it convenient to screw the fastening bolt 15 .

[0033] Slots 17 are provided on the sides of the first door panel 2 and the second door panel 3 , and the inserting plate 16 is inserted into the slots 17 . Due to the installation of the slots 17 , it is convenient to insert the sealing strip 18 into the inner sides of the first door panel 2 and the second door panel 3 .

[0034] The working principle of the fire door with smoke-proof effect for the fire escape is: when using the fire door, firstly, it is necessary to move the fire door to the designated position, and then the user will pick up and move the door cover 1 and the door body. After moving to the designated position, it can be placed on the ground, and then the staff will install the fire door on the outside of the emergency passage. Since there will be a gap between the door cover 1 and the first door panel 2 and the second door panel 3, in order to better evacuate more people in an emergency, a smoke-proof structure is installed on the outside of the first door panel 2 and the second door panel 3. By providing a sleeve frame 4, a strip plate 8, a sealing plate 7, a sealing frame 5 and other structures on the outside of the door body, when an accident occurs, after closing the fire door, the strip plate 8 inside the sleeve frame 4 is moved in turn, and a groove 6 is opened inside the sealing frame 5, and a sealing plate 7 is embedded in the groove 6, so that the sealing plate 7 seals the gap, and then twists The butterfly nut 12 on the outside of the threaded rod 10 fixes the sealing structure to reduce the flow of smoke to the evacuated personnel, thereby reducing the impact on the personnel's body. This use enhances the smoke-proof effect of the fire door. Secondly, the sealing structure on the inner side of the first door panel 2 and the second door panel 3 is easily worn out after long-term use. In order to facilitate the replacement of the sealing structure, a structure that is easy to replace is installed. By providing a plug plate 16, a sealing strip 18, a sealing cover 19, a fastening bolt 15 and other structures on the outside of the door body, the fastening bolt 15 inside the circular groove 13 is reversed, and the staff removes the plug plate 16 inside the sealing strip 18 from the slot 17, and then the staff takes out the new sealing structure and replaces it. Then, the fastening bolt 15 is screwed again so that the thread is connected to the threaded hole 14 at the top of the plug plate 16. In this way, the replacement of the sealing structure can be completed, and it is relatively simple to operate.
