A protective door and its production process

Abstract

The present application relates to a protective door, which includes a door frame embedded in the wall, a door leaf arranged in the door frame, and a rotating assembly arranged on the edge of the door frame and connected with the door leaf. The door leaf includes a door cover and is fixed on the door A plurality of fitting columns in the casing, a fish skeleton body embedded between the plurality of fitting columns, and a door panel arranged at the opening of the door casing and fixed with the door casing, the door casing is filled with a door casing High-strength concrete between the door panel; the rotating assembly includes a hanging ring block fixed on the frame edge of the door frame, a hook body hanging on the hanging ring block and a connecting beam arranged horizontally; the One end of the connecting beam is fixed to the hook body, the other end penetrates into the door pocket and engages with the fish skeleton body, and the connecting beam is fixed to the concrete pouring in the door pocket. The application has the effect of improving the connection strength between the door frame and the door leaf and preventing the door leaf from falling off from the door frame.

Description

technical field [0001] The present application relates to the field of protective doors, in particular to a protective door and its production process. Background technique [0002] The protective door is a door that can resist various shock waves or heavy objects. It is generally formed by steel materials and concrete pouring. It is mainly used for the entrance of civil air defense projects and the passage of public places. [0003] Existing protective doors, such as the Chinese invention patent with the notification number CN110984805A, disclose a concrete protective door and its production process. The bolt device includes a fitting groove in the door frame and a deadbolt in the door panel, and the tongue lock is connected with a drive assembly that makes one end of the deadbolt slide in the fitting groove; The guide slideway of the lock tongue, one end of the guide slideway is connected to one end of the door panel and corresponds to the position of the fitting groove; ...

AI Technical Summary

Problems solved by technology

The hinge device in this technical solution is respectively fixed to the vertical frame edge of the door frame and the surface of the door panel, so that the self-weight load of the door panel is concentrated on the bolt connection between the hinge device and the surface of the door panel, and the hinge of the hinge device is sheet-shaped, carrying The strength is not enough, it is easy to cause the door frame and door panel to fall off

[0004] In view of the above-mentioned related technologies, the inventor believes that there is a defect that the connection strength between the door frame and the door panel is not enough, and it is easy to cause the door frame and the door panel to fall off.
