Steel fireproof door capable of enhancing fire integrity
The invention relates to the technical field of fireproof doors, and particularly relates to a steel fireproof door capable of enhancing fire integrity. The steel fireproof door comprises a door body, wherein a handle is arranged on the end face of the door body, the door body comprises two steel plates, a first fireproof layer and a second fireproof layer, the first fireproof layer and the second fireproof layer are arranged between the two steel plates, and fixing parts are arranged at the tops and the bottoms of opposite end faces of the two steel plates at intervals. According to the steel fireproof door capable of enhancing fire integrity, an external fire source can be primarily blocked by fireproof coatings arranged on the steel plates, second inorganic refractory mortar is solidified when heated, so that reinforcing ribs are prevented from deforming at high temperature and can stably support and connect the first fireproof layer and the steel plates, the two steel plates are not easily separated, fire integrity of the door body is enhanced, hollow glass can function in smoke and heat insulation, and a glass magnesium board is high in density and good in fireproof performance.
本发明涉及防火门技术领域，尤其是一种增强耐火完整性能的钢质防火门，包括门体，所述门体的端面上设置有把手，所述门体包括两组钢板和设置在两组钢板之间的第一防火层和第二防火层，两组所述钢板相对端面的顶部和底部均间隔设置有固定部件，该增强耐火完整性能的钢质防火门通过钢板上设置的防火涂层可以对外部火源进行初次阻隔，且设置的第二无机耐火泥在遇热时凝固，从而避免加强筋高温下变形，从而使得加强筋可以对第一防火层和钢板进行稳定的支撑连接，从而使得两组钢板不易分离以增强门体的耐火完整性，设置的中空玻璃可以起到隔烟隔热的作用，玻镁板的密度高且防火性能较好。
