Among them, a first interlayer is provided between the first fireproof board layer 2 and the second fireproof board layer 3, and a second interlayer is provided between the second fireproof board layer 3 and the third fireproof board layer 4. The first interlayer includes a first perlite layer unit 61 and a first hollow pipe fitting 62, and the first hollow pipe fitting 62 is used to separate two adjacent first perlite layer units 61; the second interlayer includes a second perlite layer unit 71 and a second hollow pipe fitting 72, and the second hollow pipe fitting 72 is used to separate two adjacent second perlite layer units 71.

[0023] In this embodiment, by providing the first fireproof board layer 2, the second fireproof board layer 3, and the third fireproof board layer 4, and arranging the first perlite layer unit 61 and the first hollow pipe fitting 62 between the first fireproof board layer 2 and the second fireproof board layer 3, and arranging the second perlite layer unit 71 and the second hollow pipe fitting 72 between the second fireproof board layer 3 and the third fireproof board layer 4, the formed fireproof and heat-insulating door has good structural strength, and the multi-layer protection structure makes the fireproof and heat-insulating reliability high.

[0024] To improve the fireproof effect around the fireproof and heat-insulating door, a fireproof strip 8 is provided between the first fireproof board layer 2 and the third fireproof board layer 4 in this embodiment. The fireproof strip 8 is arranged around the second fireproof board layer 3, and the periphery of the fireproof strip 8 is connected to the first panel layer 1 and the second panel layer 5.

[0025] Among them, the first panel layer 1 and the second panel layer 5 are made of metal plates, preferably made of stainless steel plates.

[0029] The first hollow pipe fitting 62 and the second hollow pipe fitting 72 in this embodiment are both metal square pipes. The square pipe structure can, on the one hand, enhance the structural strength of the door body without adding too much weight, and on the other hand, facilitate the production and assembly of the door body, while ensuring that each fireproof and heat-insulating structure is closely attached, better playing the fireproof and heat-insulating effect.
