Long-time-effect fireproof door leaf
The invention relates to a long-time-effect fireproof door leaf which is used in cooperation with a door frame, the door leaf comprises an outer wrapping layer and an inner core layer, the inner core layer is arranged in the outer wrapping layer, the outer wrapping layer wraps the inner core layer, an adaptive extrusion device is installed on the inner core layer, and the adaptive extrusion device stretches out of the outer wrapping layer towards the side edge of the door leaf after being heated to abut against the door frame; when the door leaf is closed, the door frame adaptively extrudes the door leaf; a plurality of heat dissipation cavities are formed in the inner core layer, each heat dissipation cavity communicates with a plurality of air blowing pipes leading to the outer side of the door leaf, a heat dissipation water bag assembly is installed in each heat dissipation cavity, and the heat dissipation water bag assemblies are damaged after being heated so that water can enter the heat dissipation cavities; the two ends of the reset device are installed on the door leaf and the door frame respectively, and smoke leakage can be avoided for a long time.
本发明涉及长时效防火门扇，与门框配合使用，门扇包括外包层和内芯层，内芯层设置于外包层内，外包层包覆内芯层，内芯层上安装有适应性挤压装置，适应性挤压装置受热后向门扇侧边伸出外包层而顶住门框；门扇关闭时门框适应性挤压门扇；内芯层开设有若干散热腔，各散热腔均连通有若干通向门扇外侧的吹气管，各散热腔内均安装有散热水包组件，散热水包组件受热后破损而使水进入散热腔；复位装置的两端分别安装在门扇和门框上，能长时间避免烟气泄露。
