Detailed Description
The steel fireproof door comprises a steel door leaf 1, wherein the door leaf 1 is hollow and is provided with a cavity 2, the cavity 2 forms an inner layer 21 and an outer layer 22, the inner layer 21 is filled with fireproof materials 3, and the outer layer 22 is filled with fireproof rubber 4;
a plurality of elastic pieces 5 for supporting the fire-resistant rubber 4 are arranged on the inner wall of the outer layer 22, the elastic pieces 5 are in a compressed state in a normal state, the elastic pieces 5 have a certain release amount, high-pressure gas is filled in the inner side of the fire-resistant rubber 4 in the outer layer 22, a plurality of blind holes 41 are formed in the fire-resistant rubber 4, and the high-pressure gas flows into the blind holes 41;
the edge sealing 6 at the periphery of the door leaf 1 is made of combustible materials.
Further, the fireproof rubber 4 is provided with an insertion hole 42 for the elastic member 5 to penetrate;
Further, a liquid medium 7 is arranged in the outer layer 22, and the liquid medium 7 can be gasified at a high temperature.
Further, the insert rod 51 is made of a heat conducting material, and the insert hole 42 is deep and is arranged close to the edge sealing 6.
The preparation method of the steel fireproof door is carried out according to the following steps:
1) Manufacturing a door leaf 1, separating a cavity 2 in the door leaf 1 into an inner layer 21 and an outer layer 22 through a partition plate, and filling fireproof materials 3 in the inner layer 21;
2) Manufacturing the elastic part 5, installing the elastic part 5 in the outer layer 22, and then arranging a combustible seal edge 6 around the door leaf 1;
3) High-pressure gas and liquid medium 7 are filled into the outer layer 22 through the gas filling holes and the liquid filling ports.
The invention will be further described below for a better understanding of the invention: when a fire disaster happens, after the sealing edge 6 is burnt, the fire-resistant rubber 4 arranged in the outer layer 22 is popped out from the outer layer 22 under the action of the elastic piece 5 because the fire-resistant rubber 4 is not restrained by the sealing edge 6, and the fire-resistant rubber 4 is abutted against a door frame to form sealing so as to block or delay the diffusion of smoke; the blind hole 41 is formed in the fire-resistant rubber 4, so that high-pressure gas flows into the blind hole 41, the fire-resistant rubber 4 is pressed due to the existence of the high-pressure gas, the fire-resistant rubber 4 is attached to a door frame more tightly, the fire-resistant rubber 4 is pressed transversely due to the existence of the high-pressure gas, the fire-resistant rubber 4 is flatter, the generation of a gap between the fire-resistant rubber 4 and the door frame is reduced, or the size of the gap is reduced, and the diffusion of smoke is further prevented; the fire-resistant door is further provided with the liquid medium 7, and the liquid medium 7 is gasified to generate gas after a fire disaster happens, so that the pressure of the gas in the outer layer 22 is further increased, the fire-resistant rubber 4 is pressed, the fire-resistant rubber 4 is further ensured to be tightly attached to a door frame, and the diffusion of smoke is blocked.
The structure of the elastic part 5 enables the fire-resistant rubber 4 to be pushed out smoothly when being pushed out, the fire-resistant rubber 4 does not incline, the attaching degree of the fire-resistant rubber 4 and a door frame is further ensured, and the diffusion of smoke is further blocked, so that the fireproof door has good fireproof performance.
