Description
Technical Field
The utility model relates to a protective equipment technical field, concretely relates to steel construction threshold biparting protective airtight door.
Background
The protective airtight door is also called a civil defense door, and refers to protective equipment installed at an entrance and an exit of civil protection engineering, and is mainly used for blocking shock waves and isolating toxic gases, and when an accident occurs, the safety of people can be guaranteed by closing the protective airtight door. According to the opening and closing mode of the protective airtight door, the door can be divided into a fixed door threshold, a falling type door threshold and a movable door threshold. The fixed doorsill has low manufacturing cost, but cannot move, so that people and vehicles cannot conveniently get in and out; the falling type threshold needs to overcome gravity when being opened and closed, the required driving power is large, and the manufacturing cost is high. Therefore, the movable threshold protective airtight door with lower manufacturing cost and convenient opening and closing is more and more favored.
The existing movable doorsill protective airtight door usually comprises a door frame and door leaves, and can be divided into single leaves and double leaves according to the number of the door leaves, and the door leaves are formed by pouring reinforced concrete. In the design of the steel structure movable threshold double-leaf protective airtight door, an airtight lock is arranged between the door leaf and used for locking the door leaf.
But the airtight lock structure on the current threshold protective airtight door that lives is comparatively complicated, and the staff need carry out loaded down with trivial details step when locking the door leaf to and the great strength of cost, thereby make threshold protective airtight door that lives use inconvenient, waste time and energy.
