Embodiment Construction

[0037] The following is attached Figure 1-4 The application is described in further detail.

[0038] The embodiment of the present application discloses a concrete protective door. refer to figure 1 and figure 2 , The concrete protective door includes a door panel 1, and the door panel 1 includes a frame 11 and a reinforcement cage 2 fixedly arranged in the frame 11. The frame 11 is rectangular, and an installation groove 12 is opened on the inner side wall of the frame 11 , and the edge of the reinforcement cage 2 is embedded in the installation groove 12 .

[0039] refer to figure 2 and image 3, the two sides of the reinforcement cage 2 are the first surface 22 and the second surface 23 respectively. The reinforcement cage 2 includes a middle cage 21 and an edge cage 3 arranged along the edge of the middle cage 21 . The edge cage 3 includes several transverse reinforcement bars 31 and four longitudinal reinforcement bars 32 , the shape of the transverse reinforcem...

Abstract

The invention relates to a concrete protective door. The concrete protective door comprises a door plank; the door plank comprises a frame and a reinforcement cage fixedly arranged in the frame; a mounting groove is formed in the inner side wall of the frame; the reinforcement cage comprises a middle cage body and edge cage bodies arranged along the edge of the middle cage body; the size of the middle cage body is smaller than that of the inner side edge of the frame; at least one edge cage body is hinged to each side edge of the middle cage body; two opposite side faces of the reinforcement cage include a first face and a second face respectively; the rotating axes of the edge cage bodies are parallel to the side faces, close to the middle cage, of the edge cage bodies; and the rotating axis of each edge cage body is located on a first face of the middle cage body. Compared with the process that steel bars are sequentially placed in the door plank and welded, the process is simpler and faster, and the effect of increasing the production speed of the door plank is achieved.

Description

technical field [0001] The present application relates to the field of personal air defense equipment, in particular to a concrete protective door and its production process. Background technique [0002] The civil air defense project is an important facility to prevent sudden enemy attacks, effectively cover personnel and materials, and preserve war potential; it is an engineering guarantee to persist in urban combat and long-term support for anti-aggression wars until victory. The protective door at the entrance and exit of this kind of project is the weak part of anti-blast and protection, and an important barrier to ensure the safety of the internal space of the project. [0003] The protective doors at the entrances and exits of civil air defense projects usually adopt reinforced concrete structures, which can resist the shock waves generated by explosions. At present, the concrete protective door usually includes a door frame, a door panel, a hinge device and a door b...
