Large-scale steel heat-insulation fireproof door with enhanced fire-resistant integrity
The invention relates to a large-scale steel heat-insulation fireproof door with enhanced fire-resistant integrity. The large-scale steel heat-insulation fireproof door comprises a door plate and a water cooling system, wherein the door plate comprises a door frame and a door leaf; the door frame and the door leaf are made of heat-resistant steel; a cavity which is distributed in a circuitous manner is concavely formed in the door leaf; two groups of water filling nozzles which are distributed up and down are formed in the vertical edge of one side, on the door leaf, of the cavity; the two groups of water filling nozzles face the hinged end of the door leaf and the door frame; the door frame is embedded and fixed on a wall body; and the water cooling system comprises two groups of steel pipes which are pre-buried in the wall body and are arranged up and down, connecting pipes which are in sealed insertion connection with the water filling nozzles, and hoses for connecting the connecting pipes with the steel pipes. According to the large-scale steel heat-insulation fireproof door provided by the invention, the fireproof door is cooled in a fire disaster environment through a water cooling manner, so that when a fire disaster occurs, the fireproof door is cooled through continuous water conveying of the water cooling system, and the temperature of the fireproof door is in a controllable range all the time; and the fire-resistant integrity performance of the fireproof door is improved and the time of keeping the structural integrity of the fireproof door is prolonged, so that the protection on indoor life and property safety when the fire disaster occurs is improved.
本申请涉及增强耐火完整性的大型钢质隔热防火门，其包括门板及水冷系统，门板包括门框及与门扇，门框及门扇均为耐热钢材质，门扇内部凹设有迂回分布的空腔，空腔在门扇的一侧竖直边沿上开设有两组上下分布的注水口，两组注水口朝向门扇与门框的铰接端；门框嵌固在墙体上，水冷系统包括预埋在墙体的、上下设置的两组钢管、与各组注水口密封插接的接管及连接接管及钢管的软管。本申请通过水冷的方式实现了防火门在火灾环境下的降温，故当发生火灾时，防火门因水冷系统的持续输水降温，使防火门的温度始终处于可控的范围内，使防火门的耐火完整性性能提升，防火门保持结构完整性的时间被延长，进而提升了火灾发生时对室内生命财产安全的保护。
