Single-leaf push-pull type movable threshold protective air-tight door structure and closing method thereof

Abstract

The invention discloses a single-leaf push-pull type movable threshold protective air-tight door structure and a closing method thereof. The single-leaf push-pull type movable threshold protective air-tight door structure comprises a wall body, a door frame, lock seat mechanisms, a guide rail and a door leaf. A door opening is formed in the wall body, the door frame comprises a door-shaped frame and a movable doorsill, the door-shaped frame is connected to the wall body and located on the two sides and the top of the door opening, the movable doorsill is detachably connected to the bottom of the door opening and hermetically connected with the door frame, and sealing strips are arranged on the periphery of the door frame; the lock seat mechanisms are arranged on the wall body or the door frame and located on the two sides of the door opening; the guide rail is connected to the wall body and extends to the top of the door opening; a hanging wheel is arranged on the door leaf, the hanging wheel is slidably connected to the guide rail, and locking mechanisms are arranged on the two sides of the door leaf; and when the door leaf slides to the door frame along the guide rail, the lock seat mechanisms are matched with the locking mechanism in a limiting mode, so that the door leaf translates towards the door frame to press the closing strips to seal the door opening. A hinge-free translation structure is adopted, a large door leaf opening space is not needed, and the single-leaf push-pull type movable threshold protective air-tight door structure is more suitable for a special building environment with a small door opening space at the hole.

Description

technical field [0001] The invention relates to the technical field of protective airtight doors, in particular to a single-leaf push-pull type movable threshold protective airtight door structure and a sealing method thereof. Background technique [0002] my country's civil air defense engineering construction implements the principle of "coordinating development with economic construction and combining with urban construction" for simultaneous construction. The construction of underground space has become the main body of new civil air defense projects at present and in the future. With the obvious improvement of national defense concept and civil air defense awareness, the importance of new and existing civil air defense projects has also further increased. [0003] Civil air defense projects have played an extremely important role in wars, urban development, and national security. Civil air defense basements and civil air defense operations headquarters have played an i...

Problems solved by technology

For example, in the civil air defense basement, subway civil air defense and commercial Unicom entrance, etc., there is insufficient protection space, and it is not convenient to install flat-opening civil air defense equipment.

If the traditional blocking plate structure is used, it takes a long time to switch between peacetime and wartime, and it consumes a lot of manpower, and the storage and daily maintenance of the blocking plate is also a long-term, time-consuming and labor-intensive task.

[0005] And, the civil air defense door of existing door-shaped structure is the side-opening type civil air defense door that connects with hinge leaf, needs larger door leaf opening space
