Embodiment
[0035] Embodiment: a kind of production technology of steel door air defense door, comprises the following steps:
[0036] a. Cutting: according to the design requirements, cut and cut the board, etc., mark the surface of the board after cutting, and classify and stack according to the panel material, frame material and steel cage material;
[0037] b. Straightening: Straightening and leveling is required for the board, so that the board can be kept flat;
[0038] c. Frame assembly: build an assembly platform, set the top of the assembly platform horizontally, and then weld the plates that make up the frame together on the assembly platform. After the welding is completed, clean the welding slag at the welding place and smooth the welding place with a grinding wheel;
[0039] d. Panel assembly: Weld multiple assembled panels to form a complete panel. After the panel is welded, remove the welding slag from the welded position and polish the welded place with a grinding whee...

The invention discloses a production process of a steel door civil air defense door, relates to the technical field of civil air defense door production, and solves the problem that the frame and door panels are easily corroded during the concrete curing process in the existing civil air defense door production. The main points of the technical scheme include the following Steps: a. cutting; b. Straightening; c. Frame assembly; d. Panel assembly; e. Welded reinforcement cage; f. Steel cage welding; g. Build a pouring platform; h. Spray vinyl chloride resin plastic solution; i. concrete pouring; j. Concrete maintenance; k. Welding of the panel: Weld the frame first, spray a layer of perchlorethylene resin plastic solution evenly on the frame, and then pour and maintain the concrete, and use the film formed after the perchlorethylene resin plastic solution is dried to isolate water vapor, so that During the maintenance process, it is not easy to cause corrosion to the frame. After the maintenance is completed, the panel is welded, so that the panel is not easy to rust.
Description
technical field [0001] The invention relates to the technical field of civil air defense door production, more specifically, it relates to a production process of steel door civil air defense doors. Background technique [0002] The civil air defense door is the door of the entrance and exit of the civil protection project. Due to the special use environment of the civil air defense door, the impact resistance and structural strength of the civil air defense door have high requirements. Door impact resistance and structural strength requirements. [0003] During the production process of existing civil air defense doors, it is first necessary to weld and build the four side frames of the civil air defense door through steel plates, then weld reinforcing ribs and reinforced steel plates in the frame of the door, and finally weld the two panels of the door It is welded to the frame, and finally concrete is poured into the door, and then the concrete is cured. Concrete curing...
