Fireproof door
The invention relates to a fireproof door. The door comprises a door frame, a first door leaf connected with the door frame, a second door leaf connected with the door frame, and a fireproof structurefor fire prevention and heat insulation. The fireproof structure comprises a first fireproof structure, a second fireproof structure and a third fireproof structure. The third fireproof structure islocated between the first fireproof structure and the second fireproof structure. The door frame comprises a first door frame main body, a second door frame main body and a cold break bridge structurebetween the first door frame main body and the second door frame main body. By forming three barriers for smoke and hot gas leakage through the first fireproof structure, the second fireproof structure and the third fireproof structure, the fireproof level of the fireproof door is greatly improved. After testing, the fireproof time of the fireproof door is more than 1.5 hours, and meets the ClassA fireproof requirements.
本发明涉及一种防火门，包括门框、与所述门框相连接的第一门扇、与所述门框相连接的第二门扇以及用于防火隔热的防火结构；所述防火结构包括第一防火结构、第二防火结构以及第三防火结构，所述第三防火结构位于所述第一防火结构与所述第二防火结构之间；所述门框包括第一门框主体、第二门框主体和位于所述第一门框主体与所述第二门框主体之间的断冷桥结构。本发明通过第一防火结构、第二防火结构以及第三防火结构形成三道屏障，烟气及热气泄露需要通过这三道屏障，从而大大提高了防火门的防火级别，经检测，防火门的耐火时间为1.5小时以上，达到了甲级防火要求。
