A beam for reinforcing the structure of an aircraft is located inside the fuselage of the aircraft. The fuselage includes at least one pressurized zone (P) that is separated by at least one airtight wall (18) of at least one other non-pressurized zone (16), the beam and the at least one airtight wal
A beam for reinforcing the structure of an aircraft is located inside the fuselage of the aircraft. The fuselage includes at least one pressurized zone (P) that is separated by at least one airtight wall (18) of at least one other non-pressurized zone (16), the beam and the at least one airtight wall being intersecting. The beam traverses the at least one airtight wall (18) that includes a cutaway that is adapted to the section of the beam, whereby sealing elements (30) are provided to ensure the sealing between the beam and the airtight wall (18) that is traversed.

The invention claimed is: 1. A beam for reinforcing the structure of an aircraft, the beam being located inside the fuselage of the aircraft, the fuselage including at least one pressurized zone that is separated by at least one airtight wall from at least one non-pressurized zone, wherein the beam intersects the at least one airtight wall, wherein the beam traverses the at least one airtight wall, the at least one airtight wall including a cutaway that corresponds to the intersecting section of the beam, wherein sealing means are provided to ensure sealing between the beam and the at least one airtight wall that is traversed, and wherein the beam has a hollow section and comprises therein at least one airtight partition essentially in the same corresponding plane as the at least one airtight wall traversed by the beam. 2. The beam according to claim 1, wherein the beam is made of composite materials. 3. The beam according to claim 1, wherein the beam comprises a lower U-shaped cap whose branches are surmounted by two lateral inverted L-shaped longitudinal beams on which rests a planar upper cap. 4. The beam according to claim 1, wherein the beam comprises a lower U-shaped cap and an upper inverted U-shaped cap. 5. The beam according to claim 1, wherein the beam comprises at least one longitudinal rib that extends over at least one portion of the length of the beam. 6. The beam according to claim 1, wherein the beam comprises at least one transversal reinforcement rib. 7. The beam according to claim 6, wherein the beam comprises plural said transversal ribs distributed over the length of the beam so as to reinforce the beam in zones subjected to constraints acting in a plane that is essentially transversal to the beam. 8. The beam according to claim 1, wherein the sealing means comprise at least one L-shaped angle bar. 9. The beam according to claim 1, wherein the beam is a ventral beam. 10. Aircraft structure comprising, at least one airtight wall that separates a pressurized zone from a non-pressurized zone, and at least one beam that is inside the fuselage of the aircraft, wherein the at least one beam intersects the at least one airtight wall, wherein the at least one airtight wall comprises a cutaway corresponding to the intersecting section of the at least one beam, wherein the at least one beam traverses the at least one airtight wall at the cutaway, wherein sealing means are provided to ensure sealing between the at least one beam and the traversed at least one airtight wall, and wherein the at least one beam includes a hollow section and comprises therein at least one airtight partition essentially in the same corresponding plane as the at least one airtight wall traversed by the at least one beam. 11. The aircraft structure according to claim 10, wherein the at least one beam is made of composite materials. 12. The aircraft structure according to claim 10, wherein the at least one beam comprises a lower U-shaped cap whose branches are surmounted by two lateral inverted L-shaped longitudinal beams on which rests a planar upper cap. 13. The aircraft structure according to claim 10, wherein the at least one beam comprises a lower U-shaped cap and an upper inverted U-shaped cap. 14. The aircraft structure according to claim 10, wherein the at least one beam comprises at least one longitudinal rib that extends over at least one portion of the length of the beam. 15. The aircraft structure according to claim 10, wherein the at least one beam comprises at least one transversal reinforcement rib. 16. The aircraft structure according to claim 15, wherein the at least one beam comprises plural said transversal ribs distributed over the length of the at least one beam so as to reinforce the at least one beam in zones subjected to constraints acting in a plane that is essentially transverse to the at least one beam. 17. The aircraft structure according to claim 10, wherein the sealing means comprise at least one L-shaped angle bar. 18. The aircraft structure according to claim 10, wherein the at least one beam is a ventral beam.
