Referring to fig. 10 and 12, in one embodiment, the civil air defense door 100A further includes an anchoring hook assembly 30A, the anchoring hook assembly 30A is connected with the hinge 23 and the civil air defense door 100A respectively, and the anchoring hook assembly 30A is embedded in a wall body, so as to ensure the connection and installation stability of the civil air defense door frame 10A and the civil air defense door 100A, and further ensure the installation stability of the civil air defense door frame 10A.

Compared with the prior art, the invention has at least the following advantages:

in the assembling method of the civil air defense door frame, the acquired angle steel piece is provided with the arc-shaped inclined flat steel and the arc-shaped support plate, and the door frame angle steel is also provided with the door frame inclined flat steel and the door frame support plate, so that when the angle steel piece and the door frame angle steel are assembled to form the civil air defense door frame, only the door frame angle steel needs to be cut, the door frame angle steel is cut into required sizes, and the cut door frame angle steel is matched with the angle steel, namely, the arc-shaped inclined flat steel of the angle steel piece can be directly abutted and aligned with the door frame inclined flat steel of the cut door frame angle steel, the arc-shaped support plate of the angle steel piece can be directly abutted and aligned with the door frame support plate of the cut door frame angle steel, the door frame angle steel and the angle steel piece are correspondingly and fixedly connected, the situation that other parts of the door frame angle steel need to be cut and polished when the civil air defense door frame is assembled is avoided, the operation labor intensity is high, the assembly inefficiency leads to the erection work of people's air defense door long, and the difficult problem that satisfies user's demand has improved the assembly convenience nature of people's air defense door frame effectively, has saved the bending process of door frame angle steel and has reduced cutting, the polishing of backup pad and oblique band steel, has reduced the processing degree of difficulty of people's air defense door frame, has improved the assembly efficiency of people's air defense door frame.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
