FRP rib concrete structure civil defense door

Abstract

The invention relates to the technical field of air-raid shelters, and particularly to an FRP rib concrete structure civil defense door with high strength and high performance, which includes a door frame, a first door body, a linkage interlocking device, wherein the first door body is hinged with the door frame through a first rotating shaft and a hinge; the linkage interlocking device includes afixing wheel, a steel wire rope and tapered end groups; the fixing wheel includes an inner fixing wheel; the inner fixing wheel is arranged on the inner side of the first door body and in rotation connection with the first door body through a first rotating mechanism; one end of the steel wire rope is winded on the outer periphery wall of the inner fixing wheel, and the other end respectively penetrates through pin shafts of the tapered end groups and is connected with corresponding tapered ends; FRP ribs are arranged on the inner core of the FRP rib concrete structure civil defense concreteslab to reduce burden of constructors and prevent the concrete inner rebars from corrosion; meanwhile, through the interlinking design of the steel wire rope and the tapered end groups, the civil defense door is easier and more convenient to open and close, thereby guaranteeing fitting of the first door body and the door frame, and saving the opening and closing time.

Description

technical field [0001] The invention relates to the technical field of civil air defense engineering, in particular to a high-strength and high-performance FRP reinforced concrete structure civil air defense door. Background technique [0002] The civil air defense project, also known as civil defense, is a protective project built to prevent and mitigate the hazards of air strikes, protect the life and property of the country and the people, and ensure the civil air defense command, communication, and personnel and material shelter, including the protection of wartime personnel and material shelter. The underground protective building built separately for civil air defense command and medical rescue, and the basement built in combination with ground buildings that can be used for air defense during wartime. The civil air defense door belongs to the civil defense protection equipment, which must meet the requirements of protection and airtight functions. FRP bars are formed...

Problems solved by technology

When opening or closing, turn a handle to drive the connecting rod connected to the handle to rotate, thereby driving the lock head connected to the connecting rod to rotate, so that the lock head is separated from the vertical side of the door frame or opened; then turn the other handle, so that the lock head connected to the other handle via the connecting rod is separated or opened from the other vertical side of the door frame, and finally realizes the opening or closing of the door leaf. This opening or closing method is time-consuming and laborious

Moreover, the weight of this kind of civil air defense door can reach 1 ton, which is extremely inconvenient for transportation and installation.
