Patent Images
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.

Abstract
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.
