Explosion impact resisting structure and civil air defense door

Abstract

The invention discloses an explosion impact resisting structure and a civil defense door in the technical field of civil defense engineering, the explosion impact resisting structure comprises a door frame and a sliding door plank, the sliding door plank is slidably arranged in the door frame, the door frame is sleeved with a wall body, and one end of the door frame is rotationally connected with the wall body through a hinge; strong springs are fixedly connected to the two sides of the interior of the door frame, when explosion occurs outside the wall, impact force of explosion can act on the sliding door plate, the sliding door plate is pushed to compress the strong springs to slide in the door frame, the sliding door plate pushes the alignment block to slide during sliding, and through series transmission from the sliding rod to the limiting plate, the alignment block can slide in the door frame. When the sliding door plate is continuously driven by explosion impact to slide to be in contact with the limiting plate, the limiting plate can effectively limit the sliding door plate, so that the potential energy of the sliding door plate is absorbed to stop the sliding door plate, and when the explosion impact is finished, the strong spring pushes the sliding door plate to slide and reset.

Description

technical field [0001] The invention relates to the technical field of civil defense engineering, in particular to an anti-explosion impact structure and a civil defense door. Background technique [0002] Civil air defense is the measures and actions taken by the government to mobilize and organize the people to prevent enemy air attacks and eliminate future troubles. It forms a national air defense system together with air defense and field air defense. It is an important part of modern national defense, an important aspect of national economic and social development, an important part of modern urban construction, and a social welfare undertaking that benefits the country and the people. The civil air defense door is the door of the entrance and exit of the people's protection project. The classification of the civil air defense door is relatively clear. There are ordinary single and double protective airtight doors and airtight doors, living threshold single and double p...

Problems solved by technology

[0003] When the existing civil air defense doors are used for protection in dangerous situations, the protective effect of the civil air defense doors is to be locked together with the locking structure on the wall so as to protect the closed refuge space. When a fire strikes, the impact of the civil air defense door on the concrete wall is not good enough to absorb the explosion shock. An issue where doors could be directly detached from walls by blast shocks
