A section of aircraft fuselage comprises a cockpit structure (2) and a floor (4) connected to said cockpit structure. The cockpit structure (2) has an external skin (21) and a framework (22) comprising frames (23) positioned in fuselage cross sections approximately perpendicular to a longitudinal axis X in an aircraft reference frame. The floor (4) has cross members (41) extending along a lateral axis Y. In accordance with the invention the cross members (41) and the frames (23) are disconnected and each cross member (41), at opposite ends (414), is fixed to the cockpit structure (2) by an intermediate structural assembly (24, 29) connected on the one hand to the cross member (41) and on the other to the external skin (21) and/or to one or more frames (23).
Un tronçon de fuselage d'aéronef comporte une structure de coque (2) et un plancher (4) solidaire de ladite structure de coque. La structure de coque (2) comporte une peau extérieure (21) et une ossature (22) comportant des cadres (23), positionnés suivant des sections de fuselage sensiblement perpendiculaires à un axe longitudinal X dans un repère aéronef. Le plancher (4) comporte des traverses (41) s'étendant suivant un axe latéral Y. Suivant l'invention, les traverses (41) et les cadres (23) sont désolidarisés et chaque traverse (41), au niveau d'extrémités opposées (414), est fixée à la structure de coque (2) par un ensemble structural intermédiaire (24, 29) solidaire d'une part de la traverse (41) et d'autre part de la peau extérieure (21) et ou d'un ou plusieurs cadres (23).
