Protective door and production technology thereof

Abstract

The invention relates to a protective door. The protective door comprises a door frame embedded in the wall, a door leaf arranged in the door frame and a rotating assembly which is arranged on the edge of the door frame and connected with the door leaf, wherein the door leaf comprises a door pocket, multiple embedment columns fixed to inside of the door pocket, fish skeleton bodies embedded between the embedment columns and a door sheet arranged at an opening of the door pocket and fixed with the door pocket, and high-strength concrete filling space between the door pocket and the door sheet is poured into the door pocket; the rotating assembly comprises a hanging ring block fixed to the edge of the door frame, a hanging hook body hung on the hanging ring block and a connecting beam whichis horizontally arranged; and one end of the connecting beam is fixed with the hanging hook body, the other end penetrates into the door pocket and is clamped with the fish skeleton bodies, and the connecting beam is in casting fixation with the concrete in the door pocket. The protective door has the effects of improving connecting strength between the door frame and the door leaf and preventingthe door leaf and the door frame from falling off.

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.
