Abstract

The invention relates to a concrete air defense door, which comprises an outer door frame pre-buried in the wall and a door body assembly rotatably connected to the inner side of the outer door frame. Disassemble the inner door panel connected to the installation frame; one side of the outer door frame is provided with a hinge seat to connect with the hinge shaft of the installation frame; the installation frame includes a bottom beam fixed on the bottom edge of the outer door panel, and side beams fixed on both sides of the outer door panel And the top beam connected to the top edge of the outer door panel, the bottom beam, the side beam and the top beam form a mounting frame of a rectangular frame structure; the inner door panel includes a plurality of concrete slabs, and the concrete slabs are embedded in the mounting frame from top to bottom Among them, the concrete slab body is provided with lightening holes penetrating through the upper and lower end faces. In the present invention, the concrete civil air defense door is disassembled into multiple modules, processed in sections, transported to the installation site for assembly, and reduces the difficulty of transportation and installation.

Description

technical field [0001] The invention relates to the technical field of civil air defense equipment, in particular to a processing technology for concrete civil air defense doors. Background technique [0002] At present, underground protection projects are also called civil air defense fortifications, which refer to underground protective buildings built separately to protect personnel and material shelter, civil air defense command, and medical rescue in wartime, as well as basements built in combination with ground buildings that can be used for air defense during wartime. The door of the entrance and exit of the underground protection project is called the civil air defense door. Among the many types of civil air defense doors, the reinforced concrete civil air defense door is widely used. The control type of its opening and closing is mainly the manual control type, that is, the civil air defense door is a manual door. As a closed civil air defense door, the reinforced c...
