Steel fireproof door crack and door frame post-grouting device and door crack post-grouting method
The invention discloses a steel fireproof door crack and door frame post-grouting device and a door crack post-grouting method, the steel fireproof door crack and door frame post-grouting device comprises a spraying pipe, the spraying pipe is provided with a closed end and an open end, a holding part is formed at the closed end, and a feeding hole is formed in the side wall of one side, far away from the holding part, of the closed end; the storage hopper is used for containing slurry, and a discharging opening of the storage hopper is connected to the feeding opening; the impeller is used for pressurizing and pushing the slurry to the open end, is rotatably mounted in the spraying pipe and is opposite to the feeding hole; the driving motor is mounted at the closed end and is in transmission connection with the impeller; the pressurizing nozzle is provided with a large opening end and a small opening end, the large opening end is detachably mounted at the opening end, an opening of the small opening end is circular or strip-shaped, and the inner diameter of the opening is smaller than that of the large opening end. The problems that a gap between an existing steel fireproof door and a wall is filled with non-combustible materials, filling is not compact easily, and the construction efficiency is low are solved.
本发明公开了一种钢制防火门门缝及门框后灌浆装置及门缝后灌桨方法，包括：喷送管，喷送管具有一封闭端和一开口端，封闭端形成有握持部，封闭端的远离握持部的一侧的侧壁开设有进料口；用于容置浆料的储料斗，储料斗的卸料口连接于进料口；用于将浆料增压推送至开口端的叶轮，可转动地安装于喷送管内，叶轮与进料口相对设置；驱动电机，安装于封闭端且传动连接于叶轮；增压喷嘴，增压喷嘴具有一大口端和一小口端，大口端可拆卸地安装于开口端，小口端的开口呈圆形或条形，开口的内径小于大口端的内径。本发明解决了现有的钢制防火门与墙体缝隙内采用不燃材料填充，存在容易填充不密实和施工效率低的问题。
