[0002] Civil defense doors are the entrances and exits of civil defense projects. In peacetime, a large number of personnel and equipment enter and exit. In wartime, the entrances and exits of civil defense doors need to be closed to prevent shock waves and poisonous gases from entering the civil defense projects. In order to ensure that the entrances and exits of civil defense doors can withstand the effects of shock waves in wartime, civil defense doors are usually welded from steel plates and filled with a large amount of fillers, making them relatively heavy. In addition, civil defense doors are mainly hinged to the door frames in the civil defense projects through triangular plates. In order to ensure the strength of civil defense doors and support the operation of civil defense doors, triangular plates are usually made of steel plates.
