Device or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to this practicality
The limitation of novel protected scope.
The utility model is described in further detail below by specific embodiment.
Specific embodiment：
The utility model provides a kind of plane airfoil combination rib, as shown in figure 1, it includes edge strip 1, lower edge strip 2, preceding
Web 3, trailing web 4 and docking angle section 5, upper edge strip 1, lower edge strip 2, leading web 3, trailing web 4 and docking angle section 5 preferably use
Aluminium alloy adds part to make；
The section of upper edge strip 1 and lower edge strip 2 is T-shaped, and its thickness is preferably 3mm~5mm, upper edge strip 1 and lower edge strip 2
Along aircraft open up to both sides be equipped with gap, stringer is inserted when being docked for wallboard, the upper limb of leading web 3 and the upper limb of trailing web 4 are equal
Mutually fixed by the lower edge of fastener and upper edge strip 1, the lower edge of leading web 3 and the lower edge of trailing web 4 pass through fastener and lower edge strip 2
Lower edge mutually fix, the lower edge of the lower edge of upper edge strip 1 and lower edge strip 2 is relative, the top surface phase of the top surface of upper edge strip 1 and lower edge strip 2
The back of the body, is fixed between leading web 3 and trailing web 4 by the T-shaped phase of docking angle section 5 in section, docks a lateral edges of the top surface of angle section 5
