The invention discloses a normally closed building fireproof door which comprises a fireproof door body used for being installed in a door frame and a door closer connected between the door frame and the fireproof door body, the fireproof door body comprises a frame structure composed of fireproof plates, and symmetrical second fireproof core plates are connected between two sets of first fireproof core plates. A supporting piece is connected between the two groups of second fireproof core plates; a plurality of cavities are formed between the fireproof plate and the first fireproof core plate, fire extinguishing filler is arranged in the cavities, a through groove is formed in the fireproof plate, the through groove is formed in the lower portion of one side of each cavity, a blocking film is arranged in each through groove, and a puncturing mechanism is installed on the outer side of the fireproof plate and used for puncturing the blocking films; due to the fact that the frame and the cavity for containing the fire extinguishing materials are installed on the fireproof door body, in the natural state, the multiple cutter assemblies are limited through the limiting mechanism, limitation is relieved through the limiting contactor when a fire breaks out, and therefore the surface of the door body is protected, and the fire extinguishing materials are discharged from the multiple through grooves.
本发明公开了一种常闭式建筑防火门，包括用于安装在门框内的防火门本体，以及连接与门框和防火门本体之间的闭门器，防火门本体包括由防火板组成的框架结构，两组第一防火芯板之间连接有对称的第二防火芯板，两组第二防火芯板之间连接有支撑件；防火板与第一防火芯板之间设有多个空腔，空腔内设有灭火填料，防火板上开设有通槽，通槽位于空腔的一侧靠下设置，通槽内设有封堵膜，防火板外侧安装有刺破机构，刺破机构用于将封堵膜刺破；由于在防火门本体上安装框架和放置灭火材料的空腔，在自然状态下，通过限制机构对多个切刀组件进行限位，而发生火灾是通过限制接触器解除限制，从而防护门本体表面从而多个通槽处排出灭火材料。
