Description

Technical Field

[0001] The utility model relates to the technical field of heat-insulating fireproof doors, in particular to a heat-insulating fireproof door. Background Art

[0002] Thermal insulation fire doors are doors specially used for fire prevention and heat insulation, which have important safety functions. With the improvement of people's requirements for building safety and fire prevention, thermal insulation fire doors have gradually become an important part of the construction industry. This kind of door has the functions of fire prevention, heat insulation, thermal insulation, sound insulation, etc., which can effectively block the spread of fire and protect the safety of people's lives and property. Thermal insulation fire doors are usually made of high-strength metal materials, and the surface is covered with high-temperature resistant materials, which have good thermal insulation properties. At the same time, the door leaf is filled with thermal insulation materials to effectively reduce heat conduction and improve the thermal insulation performance of the door body. In the event of a fire, thermal insulation fire doors can effectively isolate flames and smoke, prolong the spread of fire, buy precious time for personnel evacuation, and ensure life safety. Thermal insulation fire doors are widely used in modern buildings, especially in high-rise buildings, commercial buildings, public places and other places with high safety requirements.

[0004] 1. When the heat-insulating fire door in the prior art is installed, there will be a gap between it and the lower end of the door frame, and smoke will easily penetrate during a fire. At the same time, when the temperature is too high during a fire, the barrier life of the heat-insulating fire door will be greatly reduced. The disadvantages are: smoke is easy to penetrate: when there is a gap between the fire door and the lower end of the door frame, the smoke generated during a fire can easily penetrate through these gaps, affecting the fire prevention effect of the fire door. This may not only cause smoke to spread rapidly in the building, increase the difficulty of personnel evacuation and rescue, but also pose a threat to the life safety of personnel. Shortened barrier life: The barrier life of a fire door refers to its ability to maintain its fire resistance for a certain period of time. However, when the temperature is too high during a fire, the barrier life of the fire door may be greatly shortened, and it cannot maintain its fire resistance for a long time. This may cause the fire door to fail prematurely in a fire and fail to play its due fire prevention role. Utility Model Content
