Emergency seam-closing type smoke-blocking flame-retardant fireproof door
The invention discloses an emergency seam-closing type smoke-blocking flame-retardant fireproof door, and belongs to the technical field of fireproof doors. Magnetic push boxes are arranged on the back faces of a pair of door core plates, heat-started magnetic boosting bodies are arranged in the magnetic push boxes, and after a fire disaster occurs, the heat-started magnetic boosting bodies are subjected to high temperature to relieve the magnetic shielding influence of the heat-started magnetic boosting bodies; seam-closing pieces located on the two sides of the magnetic push boxes are pushed outwards, so that the pair of seam-closing pieces located in the middle abut against each other in an embedded mode, the seam-closing pieces located on the two sides correspondingly abut against the inner wall of a fireproof frame in an embedded mode, the middle door seam and the door seams on the two sides are correspondingly sealed, and smoke is effectively prevented from spreading from the door seams to other places without smoke; and after the seam-closing pieces are moved, a source extinguishing hole in the bottom of a source extinguishing suspension box is exposed, so that flame-retardant gas and deionized water in the flame-retardant filling layer are easy to overflow front and back, and the flame-retardant and smoke-blocking effects of the seam-closing pieces are improved through the mutual cooperation of the flame-retardant gas and the deionized water.
本发明公开了一种应急闭缝型阻烟阻燃防火门，属于防火门技术领域，通过在一对门芯板的背面均设置磁推箱，磁推箱的内部设置有受热启磁助推体，当遇到火灾后，受热启磁助推体受高温而解除其所受到的磁屏蔽影响，对位于磁推箱两侧的闭缝片向外推出，从而位于中部的一对闭缝片相抵嵌设，位于两侧的闭缝片分别与防火框内壁相抵嵌设，分别对中部门缝以及两侧门缝起到密封作用，有效防止烟气从门缝处向其他未有烟气的场所蔓延，而闭缝片被移位后便裸露出灭源悬吊箱底部的灭源孔，从而易于阻燃填充层内部的阻燃气体以及去离子水前后溢出，阻燃气体以及去离子水的相互配合，提高闭缝片的阻燃、阻烟效果。
