Abstract

The invention discloses a concrete civil air defense door and a production process thereof, and belongs to the technical field of civil air defense door processing. The concrete civil air defense doorcomprises a door frame, wherein two steel bar frameworks with the same structure are sequentially placed in the door frame, and a sandwich mechanism used for separating the two steel bar frameworks is placed on the portion, positioned between the two steel bar frameworks, of the door frame; the sandwich mechanism comprises two steel plates, a cavity is formed between the two steel plates, a discharging cylinder is jointly and fixedly arranged in the middle of the two steel plates, and the discharging cylinder is used for communicating the two steel bar frameworks; and guide plates are symmetrically and fixedly arranged on the two sides of the door frame, and a guide groove is formed in the position, corresponding to the corresponding guide plate, of each steel plate. The civil air defensedoor has the advantages that the weight of the civil air defense door is reduced, and the opening and closing of the civil air defense door are facilitated.

Description

technical field [0001] The invention relates to the technical field of civil air defense doors, in particular to a concrete civil air defense door and a production process thereof. Background technique [0002] The civil air defense door is the door of the entrance and exit of the civil protection project. The classification of the civil air defense door is relatively clear. There are ordinary single and double protective airtight doors and airtight doors, and a variety of civil air defense equipment such as single and double protective airtight doors and airtight doors with living thresholds. [0003] Among them, single-leaf doors will use steel plates to make door leaves when making single-leaf doors. The door leaves made of steel plates can meet the requirements in terms of structural strength and protective performance, but the cost of steel plate door leaves is generally high, so concrete is often used to make door leaves. However, Concrete is completely poured in the c...
