DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0026] The specific embodiments are given below.

[0027] Please refer to Figures 1-5 The present application provides a fire door and window with fireproof effect, comprising a door frame 1 and a door body. The door frame 1 is made of high-quality steel. A door plate slot 2 is formed on the front side of the door frame 1. An expanded fireproof mechanism is arranged on the door plate slot 2. The expanded fireproof mechanism prevents flames from entering the room through the gap between the door frame 1 and the door body. A door body fireproof mechanism is arranged on the door body. The door body fireproof mechanism improves the fireproof performance of the door body. The door body comprises a front door plate 3 and a rear door plate 4. The front door plate 3 is adapted to the door plate slot 2. The rear door plate 4 is adapted to the inner side of the door frame 1. When closed, the front door plate 3 is attached to the door plate slot 2. A lock body 5 is arranged on the front door plate 3. The rear door plate 4 is placed in the door frame 1. A lock hole 6 is arranged in the door plate slot 2. The lock body 5 is adapted to the lock hole 6. The door frame 1 and the door body are closed and locked.

[0028] Further, as Figure 2 and Figure 3As shown, the expansion fireproof mechanism includes a frame slot 7 opened on the door panel slot 2, a cover plate 8 is detachably arranged in front of the frame slot 7, the frame slot 7 is filled with expanded graphite powder 9, a plurality of holes 10 are uniformly arranged on the frame slot 7, a wax stick 11 is arranged in the hole 10, and a film layer 12 is arranged on the front side of the hole 10. The expansion characteristics of the expanded graphite powder 9 are different from those of other expansion agents. When subjected to high temperature, the expanded graphite powder 9 becomes a very low-density worm due to the decomposition of the compound absorbed in the interlayer lattice. The expanded graphite can form a very good thermal insulation layer on the surface of the flame retardant material, which can effectively insulate heat, has low heat release rate in fire, small mass loss, and less smoke. When a fire occurs, the flame will damage the film layer 12 and melt the wax stick 11 in the hole 10, and the expanded graphite powder 9 will rapidly expand to quickly fill the gap between the door panel slot 2 and the front door panel 3, thereby blocking the flame and preventing the flame from entering the room through the gap between the door frame 1 and the door body.

[0029] Further, as shown in Figure 4 and Figure 5 , the front door panel 3 and the rear door panel 4 are integrally formed, and the door body fireproof mechanism includes a lining shell 13 arranged on the inner side of the front door panel 3, and a perlite powder layer 14 arranged in the lining shell 13. The interior of the rear door panel 4 is provided with a heat insulation protective layer 15, which comprises a plurality of mica layers and aerogel layers. The plurality of mica layers and aerogel layers are arranged in a spaced and bonded manner. The front door panel 3 and the rear door panel 4 are made of steel. By filling the perlite powder layer 14 in the lining shell 13 of the front door panel 3, the heat insulation is better than that of traditional cement filling, and the weight of the door body is reduced. By arranging the heat insulation protective layer 15 in the interior of the rear door panel 4, heat transfer is effectively inhibited, radiation heat transfer is effectively blocked, and the fireproof property of the door body is improved.

[0030] Further, as shown in Figure 4 and Figure 5 , the rear side of the front door panel 3 and the side of the rear door panel 4 are respectively provided with fireproof sealing strips 16. When a fire occurs, the fireproof sealing strips 16 will expand due to heat, so that the fireproof sealing strips 16 are tightly attached to the door frame 1 and the door panel slot 2, thereby preventing the flame from entering the room through the gap between the door frame 1 and the door body.

[0031] Further, as shown in Figure 1 , the lower part of the door body has a high-temperature explosion-proof window 17 made of high-temperature resistant double-layer tempered glass, which is convenient for observing the fire outside the door body.

[0032] Further, as shown in Figure 1 , the door frame 1 and the door body are provided with a door closer 18. When the door is opened, the door can be automatically closed by the door closer 18. It can also ensure that the door is accurately and timely closed to the initial position after being opened, thereby avoiding the situation that when a fire occurs, the door is not closed and the flame directly enters the room.

[0033] Working principle: through the door frame 1 and the door body is provided with door closer 18, and set lock body 5 and lock hole 6, when the door body opens, can be through the door closer 18 and automatically close the door, lock body 5 and lock hole 6 lock, close the door body to the initial position, so as to avoid when the fire occurs, the door body is not closed, the flame directly enters the room;

[0034] Through the structure of the door body fireproof mechanism, the pearl powder layer 14 is filled in the lining 13 of the front door plate 3, which is better than the traditional filling cement in heat insulation, and the weight of the door body is reduced, the heat insulation layer 15 is arranged in the rear door plate 4, which effectively inhibits heat transfer and effectively blocks radiation heat transfer, and improves the fire resistance of the door body;

[0035] Through the structure of the expansion fireproof mechanism, when the fire occurs, the flame will damage the film layer 12, and the wax rod 11 in the hole 10 will be melted, the expanded graphite powder 9 will be rapidly expanded, the gap between the door plate groove 2 and the front door plate 3 will be rapidly filled, the flame will be blocked, and the flame will not enter the room through the gap between the door frame 1 and the door body.

[0036] The above shows and describes the basic principle, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the present application.
