Problems solved by technology

[0003] In the prior art, when making the door frame, it is necessary to weld the anchor hook connected to the wall on the outer wall of the door frame. However, during the welding process, due to the high temperature, the door frame may be deformed to a certain extent. When used, the airtight effect between the door leaf and the door leaf may be greatly reduced, and the assembly is not precise enough

Embodiment Construction

[0062] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0063] Such as figure 1 Shown is a reinforced concrete airtight door disclosed by the present invention, which includes a door leaf 1 and a door frame 2 that are hinged and used in cooperation with each other. The door leaf 1 can rotate relative to the door frame 2 to realize the opening and closing of the door leaf 1 .

[0064] The door leaf 1 includes a door body 11 made of concrete pouring and a frame 12 covering the periphery of the door body 11 . The door leaf 1 has a rectangular shape as a whole, and the frame 12 is enclosed by four channel steels 121 welded together. A pair of hinge ears 122 are fixedly provided on the outer side of the frame 12 in the length direction, and the two hinge ears 122 are respectively located at the upper and lower ends of the door leaf 1 . A pair of locks 3 are provided on the door body 11 on a side away from the hinge ea...

Abstract

The invention relates to a reinforced concrete airtight door and a moulding processing technology thereof, which relate to the technical field of human defense equipment processing. A technical schemecomprises the following steps: step A: making a frame; step B: welding hinge ears on the side wall of the frame; step C: pouring concrete in the frame to form a prefabricated door leaf; step D: performing maintenance treatment on the door leaf; step E: prefabricating angle steel; step F: performing calibration and straightening treatment on the angle steel, and making a door frame; step G: assembling between a door sill and the door frame; and step H: performing hinged assembly between the door leaf and the door frame. The reinforced concrete airtight door and the moulding processing technology thereof are advantageous in that calibration and straightening can be performed on the door frame, so that the airtightness between the door frame and the door leaf is better in a process of usage,and matching is more precise.

Description

technical field [0001] The invention relates to the technical field of civil air defense equipment processing, in particular to a forming process for a reinforced concrete airtight door and the reinforced concrete airtight door. Background technique [0002] Reinforced concrete airtight door is a kind of door used in special environment, especially used in military places. Ordinary door can't block the penetration of bullets and high-frequency radiation, but reinforced concrete door is cheap and has better radiation protection performance. [0003] In the prior art, when the door frame is made, it is necessary to weld the anchor hook connected to the wall on the outer wall of the door frame. However, during the welding process, due to the high temperature, the door frame may be deformed to a certain extent. When it is used, the sealing effect with the door leaf may be greatly reduced, and the assembly is not precise enough. Contents of the invention [0004] Aiming at the...
