Reinforced high-flame-retardant smoke isolation steel fireproof door
The invention discloses a reinforced high-flame-retardant smoke isolation steel fireproof door, and relates to the technical field of fireproof doors. The door comprises a door frame and a steel doorbody; a first mounting groove is formed in the bottom of the steel door body; a sliding groove is formed in the opposite inner side faces of the first mounting groove; a sliding block is in sliding fit in the sliding groove, and one side face of the sliding block is fixedly connected with a smoke isolation mechanism; a magnetic strip is fixedly connected to the upper surface of a movable plate; anelectromagnet is fixedly connected to the top in the first mounting groove; and the lower surface of the electromagnet magnetically attracts the upper surface of the magnetic strip. Through the design of the sliding groove, the smoke isolation mechanism, the magnetic strip, the electromagnet and a smoke sensor, when a fire occurs, the electromagnet is powered off through the smoke sensor, and thesmoke isolation mechanism moves downwards to the ground along the sliding groove; and compared with traditional heating expansion type sealing, a bottom gap can be directly reinforced and sealed without changing the environment temperature, and smoke can be effectively prevented from spreading in the early stage of the fire.
本发明公开了一种加强型高阻燃隔烟钢质防火门，涉及防火门技术领域。本发明包括门框和钢制门体；钢制门体底部开设有第一安装槽；第一安装槽一相对内侧面开设有滑槽；滑槽内部滑动配合有滑块，滑块一侧面固定连接有隔烟机构；活动板上表面固定连接有磁条；第一安装槽内顶部固定连接有电磁铁；电磁铁下表面与磁条上表面磁性相吸。本发明通过滑槽、隔烟机构、磁条、电磁铁和烟气传感器的设计，当火灾发生时通过烟气传感器使电磁铁断电，隔烟机构沿着滑槽往下移动至地面，相比传统的受热膨胀式密封能够无需根据环境温度的变化直接对底部缝隙进行增强密封的作用，能够有效防止火灾初期烟雾的蔓延。
