Claims

[Scope of utility model registration request]

The vertical frame has a double structure made of two overlapping frame materials, and a plurality of horizontal frame insertion parts are formed at regular intervals in the longitudinal direction, and the horizontal frame is made of two annular frame materials. The horizontal frame is inserted into the horizontal frame insertion part and assembled to the vertical frame to form the fuselage frame, and the peripheral part of the outer cover panel made of metal plate is bent at right angles, and these bends are Insert the part between the frame materials of the vertical frame, bend the part of the bent part that protrudes from between the frame materials along the end surface of the frame material, and then bend it along the side surface of the frame material, and then bend the part of the bent part between the frame materials. Wrap it around the vertical frame, tighten the frame materials with tightening bolts at predetermined intervals in the longitudinal direction of the vertical frame, grip and fix the bent part of the outer sheathing panel with the frame material, bend the peripheral part of the outer sheath panel at right angles,
Insert these bent parts between the frame materials of the horizontal frame, bend the parts of the bent parts that protrude from between the frame materials along the end surfaces of the frame materials, and then bend them along the side surfaces of the frame materials. An airplane fuselage structure characterized in that the frame material is wrapped around the horizontal frame, the frame material is tightened with tightening bolts at a predetermined interval in the longitudinal direction of the horizontal frame, and the bent portion of the outer cover panel is gripped and fixed by the frame material. .
