Steel fireproof door
The invention discloses a steel fireproof door, relates to the field of fireproof doors, and provides the following scheme aiming at the problem that escape is hindered due to the fact that an existing steel fireproof door is difficult to open due to the fact that the temperature rise speed is high in a fire disaster: the steel fireproof door comprises a steel shell; the shell is filled with a supporting frame used for supporting the appearance and a ceramic plate used for enhancing the fire resistance of the door plate, and the shell is further filled with cooling liquid for increasing the specific heat capacity of the door plate. A water spraying mechanism used for spraying cooling liquid is further arranged at the position, close to the door lock, of the shell, and the water spraying mechanism is of a structure for triggering water spraying based on water level fall pressure and memory metal sheet thermal deformation. In the water spraying mechanism, a sleeve is arranged at the position, close to the door lock, of the inner wall of the shell, and the sleeve is slidably connected with a spraying pipe in a sealed and sleeved mode. The steel fireproof door is novel in structure, and effectively solves the problem that an existing steel fireproof door is difficult to open due to the fact that the temperature rise speed is high in a fire disaster, and escape is hindered.
本发明公开了一种钢质防火门，涉及防火门领域，针对现有的钢制防火门在火灾中因升温速度较快导致开启困难造成逃生阻碍的问题，现提出如下方案，其包括钢制的外壳，外壳内填充有用于外形支撑的支撑架和用于增强门板耐火性能的陶瓷板，且所述外壳内还填充有增加门板比热容的冷却液；所述外壳位于门锁附近还设置有用于喷射冷却液的喷水机构，且所述喷水机构为一种基于水位落差压力和记忆金属片受热变形触发喷水的结构；所述喷水机构内：外壳内壁靠近门锁处设置有套管，且所述套管与喷管密封滑动套接。本发明结构新颖，该装置有效的解决了现有的钢制防火门在火灾中因升温速度较快导致开启困难造成逃生阻碍的问题。
