The invention concerns a pressurized flooring for aircraft, provided with beams (1) including an upper sole (2), a vertical web plate (3), and a lower sole (4), the lower sole being provided with two oblique feet (7, 8) arranged on both sides of the vertical web plate and presenting a support surface (14, 15) provided for supporting pressurized curved membranes (9), characterized in that the lower sole includes a linking element (10) connecting the two oblique feet, so that said lower sole presents an enclosed section. Such a structure can be advantageously realized in composite material.

1. An aircraft pressurized flooring, comprising: longitudinal beams each having a longitudinal axis and including a first longitudinal beam spaced apart from a second longitudinal beam and pressure resisting curved membranes, each beam, when viewed in a cross section taken perpendicular to the longitudinal axis, including an upper sole, a vertical web plate, and a lower sole, said lower sole having two oblique feet arranged on both sides of the vertical web plate, and each oblique foot presenting a support surface on which the pressure resisting curved membranes are attached, one of the pressure resisting curved membranes extending between one of the oblique feet of the first longitudinal beam and one of the oblique feet of the second longitudinal beam, wherein the beams are formed from composite material, and wherein the lower sole of the beams includes a linking element connecting the two oblique feet, so that said lower sole presents an enclosed section. 2. A floor for a pressurized aircraft comprising: longitudinal beams each having a longitudinal axis and including a first longitudinal beam spaced apart from a second longitudinal beam; andcurved pressure resisting membraneseach beam, when viewed in a cross section, having an upper sole, a vertical web plate, and a lower sole, the lower sole including two oblique feet extending from the sides of the vertical web plate, each oblique foot presenting a support surface on which the curved pressure resisting membranes are attached, wherein the beams are formed from composite material, one of the pressure resisting curved membranes extending between one of the oblique feet of the first longitudinal beam and one of the oblique feet of the second longitudinal beam, and wherein the lower sole of the beams includes a linking element connecting outer edges of the two oblique feet, so that said lower sole presents an enclosed section. 3. Flooring according to claim 1, wherein the linking element includes a horizontal surface, two opposed linking edges of said horizontal surface being each united to a lower extremity of one oblique foot, so that the enclosed section forms a triangle. 4. Flooring according to claim 1, wherein the linking element includes two oblique surfaces, one linking edge of each oblique surface being united to one lower extremity of an oblique foot, both oblique surfaces being united to one another by their opposed converging edges to the linking edges, so that the enclosed section forms a lozenge. 5. Flooring according to claim 1, wherein the vertical web plate crosses the enclosed section. 6. Flooring according to claim 1, wherein the enclosed section is hollow. 7. Flooring according to claim 6, wherein the lower sole includes a reinforcement lodged within the internal volume of the enclosed section. 8. Flooring according to claim 7, wherein an external contour of the reinforcement matches an internal contour of the enclosed section. 9. Flooring according to claim 7, wherein an external contour of the reinforcement matches an internal contour of the support surfaces and linking edges of the linking element. 10. Flooring according claim 7, wherein the reinforcement is made of composite material. 11. Flooring according to claim 1, wherein the linking element includes at least one through aperture that allows access to the internal volume of the enclosed section. 12. A floor according to claim 2, wherein the linking element comprises a horizontal surface having two opposed linking edges that are each united to a lower extremity of one oblique foot, so that the enclosed section forms a triangle. 13. A floor according to claim 2, wherein the linking element includes two oblique surfaces each having a linking edge, one linking edge of each oblique surface being united to one lower extremity of an oblique foot, both oblique surfaces being united to one another by opposed converging edges extending inwardly from the linking edges, so that the enclosed section forms a lozenge shape. 14. A floor according to claim 2, wherein the vertical web plate extends across the enclosed section. 15. A floor according to claim 2, wherein the enclosed section is hollow. 16. A floor according to claim 15, wherein the lower sole includes a reinforcement within the internal volume of the enclosed section. 17. A floor according to claim 16, wherein an external contour of the reinforcement matches an internal contour of the enclosed section. 18. A floor according to claim 16, wherein an external contour of the reinforcement matches an internal contour of the support surfaces and the linking edges of the linking element. 19. A floor according to claim 16, wherein the reinforcement is made of composite material. 20. A floor according to claim 2, wherein the linking element includes at least one through aperture that provides access to the internal volume of the enclosed section.
