[0002] The classification of civil air defense doors is quite distinct, including single-leaf and double-leaf protective closed doors and closed doors with fixed thresholds, single-leaf and double-leaf protective closed doors and closed doors with movable thresholds, and other civil air defense equipment. When installing, the civil air defense door needs to be installed through the door frame, of which the bottom door frame is one of the components of the door frame. The bottom door frame structure of the existing civil air defense door needs to be pre-buried under the ground during installation, but the existing pre-embedding method is not stable enough. During the main construction, the movable threshold embedded parts need to be embedded in the foundation under the door in advance. Some conventional embedded parts need to break the steel bars of the raft slab. After the steel bars are broken, local treatment is required to thicken the foundation locally. The construction is more troublesome and uneconomical. Utility Model Content
