[0002] As a disaster relief measure, civil air defense equipment is an important part of carrying out rescue operations, preventing and mitigating disaster hazards. Therefore, the quality requirements of civil air defense equipment are relatively strict. As people pay more attention to safety protection, the demand for civil air defense equipment is gradually increasing. Especially the civil air defense door, as an important component of civil air defense protection equipment, the civil air defense door has a high quality index, but the civil air defense door still has the problem of cumbersome assembly process, especially the general civil air defense door frame is still used in the assembly process of cutting, folding The process of bending and welding has the disadvantages of high labor intensity and low assembly efficiency, which leads to a long installation period of civil air defense doors and is difficult to meet the needs of users

The invention provides a corner steel piece, a civil air defense door frame, a preparation method of the civil air defense door frame and a civil air defense door. The corner steel piece comprises corner angle steel, arc-shaped inclined flat steel and an arc-shaped supporting plate. A first connecting face, a second connecting face and a third connecting face are arranged on the corner angle steel, the first connecting face and the second connecting face are connected in a crossed mode, and the third connecting face is connected with the first connecting face and the second connecting face. The arc-shaped inclined flat steel is connected with the corner angle steel and arranged on the third connecting face, the two ends of the arc-shaped inclined flat steel correspondingly point to the first connecting face and the second connecting face, and the two ends of the arc-shaped inclined flat steel are used for being connected with door frame angle steel. The arc-shaped supporting plate is connected with the corner angle steel, the arc-shaped inclined flat steel is arranged on the third connecting face, the two ends of the arc-shaped supporting plate correspondingly point to the first connecting face and the second connecting face, and the two ends of the arc-shaped supporting plate are used for being connected with door frame angle steel. By means of the corner steel piece, the machining efficiency and the assembling efficiency of the civil air defense door frame can be improved.
