Steel structure civil defense door and manufacturing process thereof

Abstract

The invention relates to a steel structure civil defense door. The door comprises a door frame and door bodies; the door bodies comprise the first door body, the second door body and the third door body, the first door body and the door frame are hinged by a rotating shaft, the first door body and the second door body are provided with sliding blocks, and the end, away from the first door body orthe second door body, of each sliding block is provided with an anti-shedding plate; the second door body and the third door body are provided with sliding grooves corresponding to the sliding blocksand the anti-shedding plates, the inner walls of the two sides, close to a groove opening, of each sliding groove are provided with baffles in the length direction of the sliding groove respectively,and a gap for the corresponding sliding block to slide in is formed between every two baffles; the door frame is pre-embedded in a wall, the second door body is moved to make the sliding blocks inserted into the sliding grooves, then the second door body slides to make the sliding blocks slide to the ends, away from insertion ports, of the sliding grooves, the first door body, the second door bodyand the third door body are connected with one another through the steps, and then the first door body is hinged to the door frame to complete installation. The door has the advantages of being convenient to install, disassemble, move and transport.

Description

technical field [0001] The invention relates to the technical field of civil air defense engineering, in particular to a steel structure civil air defense door and a manufacturing process thereof. Background technique [0002] Civil defense is also known as civil defense. Civil defense is an international general term. It is an activity in which the government mobilizes and organizes the masses, adopts anti-aircraft raids, disaster relief measures, implements rescue operations, prevents and mitigates disaster hazards. Civil defense doors are civil defense protection equipment. Meet the protection and sealing function requirements. Among the many types of civil air defense doors, steel structure civil air defense doors are widely used, and the control form of its opening and closing is mainly manual control, that is, civil air defense doors are manual doors. [0003] At present, these civil air defense doors on the market, in order to meet the functional requirements of prot...

AI Technical Summary

Problems solved by technology

[0003] At present, these civil air defense doors on the market, in order to meet the functional requirements of protection and sealing, most of the civil air defense door leaves are formed by pouring concrete after weaving steel mesh in standard channel steel welded with embedded pressure plates or steel plate bending frames. The forming process of channel steel and reinforced concrete in this kind of door leaf is complex and cumbersome, not only the workload is large, resource consumption is heavy, the structure is heavy, it is not easy to disassemble, and it affects the safety and efficiency of transportation and installation.
