The technical scheme is as follows: the positioning and sealing device comprises a lower support horizontally arranged in the length direction, movable threshold mounting boxes are respectively arranged above two ends of the lower support in the length direction, a door-shaped sealing groove is arranged above the two movable threshold mounting boxes, a locking box which can be matched with a door lock of a civil air defense door leaf is arranged on the sealing groove, and a hinge mounting box used for connecting a hinge of the civil air defense door leaf is also arranged on one vertical side edge of the sealing groove; the positioning and sealing device is used for being embedded in a wall body around the door opening, and the outer end face of the groove body of the sealing groove of the positioning and sealing device is arranged in parallel and level with the outer wall face of the wall body.
In a specific embodiment, the components of the positioning and sealing device are welded together.
In a specific embodiment, the positioning and sealing device is made of stainless steel.
In a specific embodiment, the sealing groove of the positioning and sealing device is filled with foam rubber.
In a specific implementation mode, the hinge mounting boxes for connecting the hinge of the civil air defense door leaf are at least two and are respectively arranged at the upper end and the lower end of the same vertical side edge of the positioning sealing device.
In a specific embodiment, the lower support is made of angle steel.
Compared with the prior art, the beneficial effects of the utility model include:
the civil air defense door leaf positioning and sealing device provided by the utility model has the advantages of simple structure, low manufacturing cost and short manufacturing period; the device enables the door leaf to be smoothly attached to the wall surface after being installed, avoids local stress concentration of the door leaf, and improves the shock resistance of the door leaf.
