Description
Technical Field
The invention belongs to the technical field of civil air defense equipment, and particularly relates to a positioning and sealing method for a door leaf of a civil air defense door.
Background
The civil air defense door generally refers to a door of civil air defense protection engineering entrances and exits, and is used for entering a door with a protection function of a regional entrance with protection measures under natural disasters such as war, earthquake and the like.
At present, from the viewpoint of the established civil air defense engineering, the traditional protective equipment products (door leaves) are mostly of reinforced concrete and steel structure types, and the door frames adopted by the type of protective equipment products are all of the same type of traditional steel door frames; the construction mode matched with the method is the same. The traditional steel door frame is mainly used for connecting a door leaf hinge in a wall positioning manner, installing sealing strips and positioning locking holes, welding an anchoring hook on the steel door frame, wherein the anchoring hook is embedded in the wall and is not welded with a wall steel reinforcement cage, the steel door frame is a product embedded part for sealing and is an auxiliary tool, and after the steel door frame is used as an independent module for adjusting the horizontal and vertical directions, the steel door frame is fixed by beating a support, and the wall is sealed by a mould for pouring concrete; and after the concrete poured on the wall meets the strength requirement, the support is removed, so that the steel door frame and the wall form a whole. The steel door frame has the advantages that the steel door frame is a product component for sealing the door leaf and an auxiliary tool, so that the steel door frame can well control the horizontal and vertical directions, and the installation requirement of the door leaf of the civil air defense door is ensured. But this structure and method also suffer from a series of disadvantages: the steel door frame is high in steel quantity and high in cost; after the steel door frame is installed, the sealing groove part of the installation sealing strip protrudes out of the outer wall surface of the wall body, so that the matching contact area of the outer wall surface of the wall body and the door leaf is small, the door leaf is not beneficial to dispersing the stress of the door leaf after being impacted, and the situation that the door leaf is damaged and the steel door frame is pulled out is easily caused under extreme conditions. Fig. 12 and 13 provide a case where a steel door frame 01 of the related art is installed in a wall 60, and a case where the steel door frame 01 is sealed with a hemmed door leaf or a steel structure door leaf 00.
Therefore, in view of the above problems, there is a need in the art for a new security door leaf positioning and sealing device and security door leaf positioning and sealing method.
