Abstract
Such a fuselage includes cross-members adapted for the formation of a floor, at least one of said cross-members including an upper part, a lower part, linkage for the lower part to the upper part, and at least one opening for the passage of systems which is delimited between the lower part and the upper part. The upper part of the cross-member is fastened to the fuselage and is dimensioned so as to bear the stresses to which said cross-member may be subjected when the aircraft remains on the ground. The lower part is fastened to the upper part so as to reinforce it such that when assembled, the upper part and the lower part are adapted to bear the stresses to which the cross-member may be subjected in flight conditions of the aircraft.

An aircraft fuselage comprising cross-members adapted for the formation of a floor, at least one of said cross-members comprising an upper part, a lower part, linkage linking the lower part to the upper part, and at least one opening for the passage of systems which is delimited between the lower part and the upper part,
- characterized in that in that the upper part of said cross-member is fastened to the fuselage and is dimensioned so as to bear the stresses to which said cross-member may be subjected when the aircraft remains on the ground, and in that the lower part of said cross-member is fastened to the upper part thereof so as to reinforce it such that when assembled, the upper part and the lower part are adapted to bear the stresses to which said cross-member may be subjected in flight conditions of the aircraft.
A method of producing a floor in an aircraft fuselage, said floor comprising cross-members forming a load-bearing structure adapted to receive floor panels and to bear systems, at least one of said cross-members being produced in two distinct parts comprising an upper part and a lower part delimiting between them at least one opening for the passage of systems, characterized in that
- in a first step only the cross-member upper part is fastened onto the fuselage
- in a second step said systems are put into place under said cross-member upper part, and
- in a third step said cross-member lower part is joined to said upper part.
