Problems solved by technology

During use, it is easily deformed and dented by the impact of gravity, and the service life is short. If criminals forcefully cut the door and enter the room, the steel panel is easily cut open
At the same time, the door of the hollow structure is not thick enough, and the noise is loud
Although the hollow steel door has a certain degree of fire resistance, it is actually not strong enough in case of fire, and it is easy to melt at high temperature.

Embodiment

[0019] As shown in the figure, a fire-proof anti-theft door includes a metal panel layer 1 and a door core layer. The door core layer is sequentially provided with a cement layer 2 and a perlite fire-proof layer 3 from the inside to the outside. An iron mesh layer 4 is arranged between the cement layer 2 and the perlite fireproof layer 3. The cement layer 2 and the perlite fireproof layer 3 have the same thickness. The thickness of the cement layer 2 is 2 cm.

[0020] The metal panel layer 1 is filled with a cement layer 2 and a perlite fireproof layer 3, which makes the door body difficult to break and deform when subjected to external forces, prolongs the service life of the door, and can effectively prevent criminals from breaking in.

Abstract

The invention belongs to the field of doors and particularly relates to a fireproof antitheft door which comprises a metal panel layer and a door core layer. The door core layer is provided with a cement layer and a perlite fireproof layer which are sequentially arranged from inside to outside. An iron net layer is arranged between the cement layer and the perlite fireproof layer. The thickness of the cement layer is equal to the thickness of the perlite fireproof layer. As the metal panel layer is filled with the cement layer and the perlite fireproof layer, a door body does not crack or deform easily when affected by external force, the service life of the door is prolonged, and criminal elements can be effectively prevented from breaking into houses.

Description

Technical field [0001] The invention belongs to the field of doors, and specifically relates to a fireproof and anti-theft door. Background technique [0002] The existing anti-theft doors are made of steel panels, and the inside of them is a steel frame hollow structure. In the process of use, it is easy to deform and dent by gravity impact, and the service life is short. When the door is cut into the room by lawbreakers, the steel panel is easily cut. At the same time, the hollow structure of the door is not thick enough, and the noise is loud. Although the hollow steel door has a certain degree of fire resistance, it is actually not strong enough in fire resistance and is easy to melt at high temperatures. Summary of the invention [0003] The purpose of the present invention is to provide a heavy fire and anti-theft door with good anti-theft effect to solve the above problems. [0004] The above technical objectives of the present invention are achieved through the following ...
