Cooling fire escape door

Abstract

The invention belongs to the field of windows and doors of fixed constructions, and particularly discloses a novel fire-proofing escape door with a cooling effect. The novel fire-proofing escape door comprises a door frame and a door body, which are made of fire-proofing core plates, wherein a door handle is respectively arranged on indoor side and outdoor side of the door body; a fire-extinguishing and cooling device is arranged on one side of each door handle, and comprises a cylinder body; a separator is arranged in each cylinder body, one end of each separator is hinged in the respective cylinder body, the other end of each separator is adhered with glue, and each separator is adhered to the inner wall of the respective cylinder body through the first glue; each cylinder body is separated into a first chamber and a second chamber by virtue of the respective separator, each first chamber is filled with aluminum sulfate, and each second chamber is filled with sodium bicarbonate; a nozzle is formed in the side wall of the top of each cylinder body, and is filled with second glue for sealing; the melting point of the second glue is higher than that of the first glue; and the nozzle is just aligned to each door handle. By adopting the scheme, the temperature of the door handles can be reduced when a fire disaster happens, so that the escape rate of people can be improved.

Description

technical field [0001] The invention belongs to the field of doors and windows of fixed buildings, in particular to a special-purpose door. Background technique [0002] Existing fire door kind is more on the market at present, and its doorframe and door leaf adopt metal to make mostly, fill refractory material in the sandwich layer of doorframe and door leaf. In order to prevent the fire from spreading, fire doors are used for the opening and closing doors of the escape passages on each floor. [0003] The Chinese invention patent document with the publication number CN104314445A discloses a new type of fireproof door, including a door frame and a door leaf made of a fireproof core board. The connection between the door frame and the door leaf is sealed by a fireproof expansion seal. There is a through hole that can allow the passage of a human body, and an escape pipe that can allow the passage of a human body is embedded in the through hole. The escape pipe is located on...

Problems solved by technology

[0004] However, when a fire occurs, the overall temperature of the door leaf will rise, making the temperature of the door handle too high for people to open the fire door to escape, and the escape pipe will also be heated by the surrounding air or fire when the fire spreads. , the heated escape tube and the sealing cover are prone to deformation, which makes the sealing cover and the escape tube fused or bonded together, resulting in the escape tube being unable to be opened, causing great losses to the safety of people's lives and property
