An aircraft fuselage structure with frames (11) running transversely with respect to the longitudinal direction of the fuselage, and main deck cross members (14) is disclosed. The aircraft fuselage structure contains premanufactured integral units (10) which each comprise at least the lower region of the fuselage frame (11) and the main deck cross member (14), the fuselage frame (11) and a region (14a) of the main deck cross member (14) that spans at least an essential part of the width of the main deck and merges on both sides into the fuselage frame (11) being premanufactured in the form of an integral component.

La présente invention concerne une structure de fuselage d'aéronef avec des cadres (11) s'étendent transversalement par rapport au sens longitudinal du fuselage et des barres transversales de pont principal (14). La structure de fuselage d'aéronef comporte des unités préfabriquées monoblocs (10) dont chacune comprend au moins la région inférieure du cadre de fuselage (11) et la barre transversale de pont principal (14). Par ailleurs, le cadre de fuselage (11) et une région (14a) de la barre transversale de pont principal (14) qui recouvre au moins une majeure partie de la largeur du pont principal et épouse de part et d'autre le cadre du fuselage (11), sont préfabriqués pour présenter la forme d'un élément constitutif monobloc.
