Cut-off end configuration, U-shaped co-curing stringer and stiffened wallboard

The utility model provides a cut-off end configuration, U-shaped co-curing stringer and stiffened wallboard, the utility model provides a stringer cut-off end configuration, the cut-off end configuration comprises an insertion layer and a rhomboid, the insertion layer is arranged between two adjacent stringer web plates, and the rhomboid is arranged between the insertion layer and the stringer web plates. The utility model has a fixed end chamfer angle which does not extend to the skin but stops when the stringer web still has a certain height. And the ends of the stringers and the rib edge strips are mutually staggered. The joint of the end head of the structure and the skin has good smoothness and attractiveness, and the structure is more reasonable. 本实用新型提供了一种截止端构型、U型共固化长桁及加筋壁板，本实用新型提供一种长桁截止端构型，所述截止端构型包括插层和捻子条，所述插层设置在相邻的两块长桁腹板之间，所述捻子条设置在插层和长桁腹板之间。本实用新型有固定的端头斜削角，并且不延伸至蒙皮，而是在长桁腹板仍有一定高度时截止。使得长桁端头与肋缘条之间相互错开。此构型的端头与蒙皮连接处有较好的平整性和美观性，结构更加合理。
