Description

Technical Field

[0001] The utility model relates to the technical field of fireproof doors, in particular to a fireproof door with smoke isolation effect. Background Art

[0002] With the rapid development of social economy and the acceleration of urbanization, the number of high-rise buildings, large public facilities and important industrial sites has increased significantly, which has put forward higher requirements for fire safety. As an important part of the internal fire separation of buildings, the existing fire doors play an important role in preventing the spread of fire. Fire doors are specially designed door bodies that can provide fire resistance stability, integrity and thermal insulation for a certain period of time when a fire occurs, thereby effectively preventing the spread of fire and smoke inside the building and winning precious time for personnel evacuation and fire rescue. However, the traditional fire door design mainly focuses on preventing the direct spread of flames, and its isolation effect on the toxic and harmful smoke generated when a fire occurs is not satisfactory.

[0003] In actual fire accidents, thick smoke is often more dangerous than open flames. It can fill the entire floor or space in a short time, reduce visibility and release a large amount of carbon monoxide and other toxic and harmful gases, seriously threatening the lives of trapped people and increasing the difficulty of evacuation and fire rescue. Although the existing fire door products on the market have reached certain standards in fire resistance, there is still a lot of room for improvement in smoke isolation efficiency and structural design optimization. Therefore, it is necessary to propose a fire door with smoke isolation effect to solve the above-mentioned problems. Utility Model Content
