Normally open type fireproof door for office building
The invention belongs to the field of fireproof doors, and particularly relates to a normally-open type fireproof door for an office building. Comprising a bottom plate, a fixing rod is arranged on the upper side of the bottom plate, a fireproof door plate is rotationally arranged with the fixing rod as the circle center, a second door frame is arranged on one side of the fixing rod, an expansion part is arranged in the second door frame, a fixing sleeve is arranged on one side of the second door frame, third moving rods are slidably arranged at one end of the fixing sleeve, and each third moving rod is fixedly connected with the fireproof door plate; the expansion component comprises a third inner cavity formed in the second door frame, a gas tank is fixedly arranged in the third inner cavity, first communicating channels are formed in the two ends of the gas tank, and an inner cavity of the gas tank communicates with the third inner cavity through the first communicating channels. The fireproof door can automatically detect the fire temperature when a fire occurs, and when the fire behavior of the first floor of the fire becomes large, the fireproof door on the floor induces that the door is automatically closed; and when explosion occurs at the fire position, the fireproof door can automatically detect and strengthen the fixation of the gate, so that the fireproof door is prevented from being destroyed by impact waves generated by explosion.
本发明属于防火门领域，尤其涉及一种用于办公楼常开式的防火门。包括底板，底板的上侧设有一个固定杆，以固定杆为圆心转动设有防火门板，固定杆的一侧设有第二门框，第二门框内设有膨胀部件，第二门框的一侧设有固定套筒，固定套筒的一端滑动设有第三移动杆，每个第三移动杆与防火门板固定连接；膨胀部件包括第二门框内设有的第三内腔，第三内腔内固定设有气罐，气罐的两端设有第一连通道，气罐的内腔与第三内腔通过第一连通道连通。本防火门在火灾发生时可自动检测火灾温度，当火灾发生的一层火势变大时，该层防火门感应到将自动关闭大门；当火灾位置处发生爆炸时，防火门将自动检测并加强大门的固定，防止爆炸产生的冲击波将防火门冲毁。
