Abstract

The invention provides a fixing structure and an installation method of an aircraft cabin craft floor. A ground rail is arranged on the cabin floor, the fixing structure comprises a ground rail fixingcomponent and a floor fixing component, and further, a hinge shaft passes through a hinge hole to connect a ground upper clamping plate with a floor installation plate together, so as to from a hingestructure. A set of symmetrical floor fixing components are installed at a predetermined position, near one side of the ground rail of an aircraft cabin, of the craft floor, and then the craft flooris laid at a predetermined position in the cabin; the corresponding upper rail clamping plate and the floor installation plate are connected together; finally, the ground rail upper clamping plate isconnected with a ground rail T-slot clamping member by screws, and a positioning key at the tail part of the ground rail T-slot clamping member is pushed to be clamped in a ground rail opening to complete the installation of the craft floor.

Description

technical field [0001] This application relates to the ground equipment technology of aircraft manufacturing process equipment, in particular to a fixed structure and installation method of aircraft process floor. Background technique [0002] During the manufacturing process of the aircraft, after the assembly of the large parts of the aircraft is completed, the debugging of the control system, the installation of various instruments and meters, and the installation of some interior decorations must be carried out inside the fuselage. During this period, the aircraft floor cannot be directly installed. . For a long time, a layer of 12-20mm thick wooden boards has been laid on the fuselage floor beams as the craft floor. The entire craft floor is made of multiple pieces of plywood spliced ​​with reference to the layout of the lower fuselage frame and the floor beams. . In the process of using craft flooring, because the floor is not fixed, there are often problems such as ...
