Fireproof door

Abstract

The invention discloses a fireproof door. The fireproof door comprises a door sheet, wherein the door sheet comprises a first refractory steel plate and a second refractory steel plate; a first ceramic thermal insulating plate and a second ceramic thermal insulating plate are arranged between the first refractory steel plate and the second refractory steel plate; a water accumulating cavity for accumulating water is formed between the first ceramic thermal insulating plate and the second ceramic thermal insulating plate; a coded lock is mounted on the door sheet; a smokeproof adhesive tape is bonded at the edge of the door sheet; and a camera is mounted above the door sheet. The fireproof door retards the flame through setting the refractory steel plates, and stops the heat through setting the ceramic thermal insulating plates at the inner layers of the refractory steel plates; meanwhile, in order to achieve a better thermal insulating effect, the hollow water accumulating cavity is formed in the door sheet, and the water accumulating water can further reduce the temperature of the door sheet after the water accumulation, so that the indoor heating process is slower to gain more rescue time for firefighters and indoor staff.

Description

technical field [0001] The invention belongs to the technical field of fire protection systems, and in particular relates to a fire door. Background technique [0002] With the popularization of high-rise buildings, the fire-fighting facilities of high-rise buildings are becoming more and more important; many people prefer to choose fire doors when they are decorating, especially when they are decorating companies. Fire doors can isolate the fire outside the door at the first time. Now Some fire doors only have basic flame-retardant properties and have no heat insulation capability. Therefore, once used in small and important rooms such as the financial office, it is easy for people in the room to be scalded by the door or injured by the high-temperature environment in the event of a fire. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a fireproof door for the above-mentioned deficiencies in the prior art. The ...
