Fireproof door for civil air defense engineering
The invention belongs to the technical field of civil air defense engineering, and particularly discloses a civil air defense engineering fireproof door which comprises a door body and a door frame, sealing layers are arranged on the door body and the door frame in a surrounding mode, and each sealing layer comprises multiple layers of plate-shaped structures which are parallel to one another and distributed at intervals. When the fireproof door is closed, the plate-shaped structures of the sealing layers on the door body and the door frame are interspersed at intervals, and gaps are reserved between the plate-shaped structures, so that labyrinth ventilation gaps are formed. The plate-shaped structure of the sealing layer can deform at high temperature. When a fire disaster occurs, the plate-shaped structures of the sealing layer can deform at high temperature, and the deformed plate-shaped structures extrude each other, so that the labyrinth type ventilation gap is blocked, a large amount of smoke is prevented from penetrating through the fireproof door through the labyrinth type ventilation gap, the daily ventilation requirement can be met, and fire spreading and smoke diffusion can be effectively prevented when the fire disaster occurs.
本发明属于人防工程技术领域，具体公开了一种人防工程防火门，包括门体和门框，门体和门框上均环绕设置有密封层，密封层均包含多层互相平行且间隙分布的板状结构。当防火门闭合时，门体和门框上密封层的板状结构互相间隔穿插并彼此留有间隙，形成迷宫式通气间隙。密封层的板状结构在高温下能够变形。火灾时，密封层的板状结构在高温下能够变形，变形的板状结构互相挤压，从而阻断迷宫式通气间隙，阻止大量烟气通过迷宫式通气间隙穿过防火门，既可以满足日常通风的要求，又可以在火灾发生时有效地防止火势蔓延和烟气扩散。
