Abstract

The invention discloses a civil air defense door based on a high barrier effect, and relates to the technical field of civil air defense doors. The civil air defense door comprises a door frame main body, the door frame main body is mainly composed of pre-buried layers, a lining frame and a sealing frame, wherein the lining frame is arranged on one side of the sealing frame and is integrally formed with the sealing frame, the pre-buried layers are arranged on the side surfaces of the lining frame, the pre-buried layers are connected with the installation position through concrete pouring, a filling sealing groove is formed in the middle position of the inner side of the sealing frame along the sealing frame, the edge position of the front side of the sealing frame protrudes forwards to form a sealing protrusion, sliding groove rods are arranged at the top and the bottom of one side of the sealing frame, and a sealing groove is formed in the edge of the outer side of the sealing protrusion. The impact force generated by explosion and damage of armor-piercing bullets can be effectively resisted, the sealing performance of the door body is higher, water seepage, toxic gas and toxic smoke flowing and the like can be effectively prevented, and the use convenience by people is greatly improved.
