Abstract

The invention discloses a fireproof door convenient to install. The fireproof door comprises stand columns and fireproof door bodies; the outer side faces of the fireproof door bodies are rotatably connected to the inner sides of the stand columns through hinges, the outer sides of the stand columns are fixedly connected to walls on the side faces through expansion bolts, a door beam is fixedly connected to a wall at the top through expansion bolts, the bottom ends of the stand columns are fixedly connected to the two ends of a doorsill, the tops of the fireproof door bodies are fixedly connected to one ends of door closers, the other ends of the door closers are fixedly connected to the door beam, and fireproof windows are fixedly installed on the fireproof door bodies. The fireproof dooris high in structural strength, light in weight, high in fireproofing efficiency, economical and practical, and installation can be completed through the expansion bolts; when a fire happens, fireproof expansion sealing strips can form a leakproof structure to isolate poisonous and harmful gas and impurity particles such as smoke and dust generated in the combustion process, so that the safety ofpersonnel seeking refuge is protected.
