Fireproof door

Abstract

The invention provides a fireproof door. The fire proof door comprises a fireproof doorframe, a first fireproof door, a second fireproof door, a vertical track, a horizontal track and a fireproof connecting plate. The second fireproof door is installed on the fireproof doorframe via the vertical track and the first fireproof door is installed on the fireproof doorframe via the horizontal track; and a closed space is formed between the first fireproof door and the second fireproof door via the fireproof connecting plate. The fireproof door is further connected with a fireproof system and the fireproof system comprises a central controller, a temperature sensor, a smoke sensor, a portrait recognizing unit and a signal receiver; the central controller is connected with the temperature sensorand the smoke sensor; the portrait recognizing unit is connected with a portrait monitoring device and receives recognition information and monitoring information from the portrait monitoring device;the central controller controls whether an oxygen maker, a fire extinguishing liquid device and an air jet device are in operation; the central controller controls a first motor to operate or a secondmotor to rotate or the first motor and the second motor to rotate simultaneously; and the central controller is connected with a switch lock via signals.

Description

technical field [0001] The invention relates to the technical field of building fire protection facilities, in particular to a fire door. Background technique [0002] Building fire protection facilities are important facilities to ensure the fire safety of buildings and the safety of personnel evacuation. They are an important part of modern buildings, including fire doors. Doors with high safety requirements are fire partitions with certain fire resistance, which are installed in fire compartments, evacuation stairwells, vertical shafts, etc. Curtain fire doors are widely used in large openings in public places to play a role in fire prevention and heat insulation. Effectively prevent the spread of fire, but the traditional curtain fire doors only rely on their own fireproof materials to play the role of fireproof and heat insulation. In some persistent fire situations, the performance of fireproof materials will continue to decline with the passage of time until they fail...
