Claim:
A floor forming a roof of a landing gear case of an aircraft, the floor comprising: two external lengthwise beams extending along a lengthwise direction of the floor and forming outside edges of the floor; a plurality of cross beams extending along a crosswise direction between the lengthwise beams, each cross beam having an external end and an internal end, wherein the external end of each cross beam is interlocked to one of the lengthwise beams, wherein the internal ends of the cross beams are connected to each other in pairs, and wherein the cross beams are tilted so that the internal ends of at least one of the pairs of cross beams are directed downward when compared to the horizontal plane of the floor; and the internal ends of the cross beams are connected to a first end of a solid vertical structure using an articulated joint, the solid vertical structure having a second end connected to a lower wall of a fuselage of the aircraft in order that deformation of the floor follows deformation of a wing of the aircraft and the fuselage; and the floor further comprising self-stiffened panels which extend between the pairs of cross beams.
