This invention relates to a pressure-sealed floor for aircraft, provided with girders (1) comprising a top flange (2), a vertical web (3) and a bottom flange (4), wherein the top flange is provided with two angled legs (7, 8) arranged on either side of the vertical web and having a supporting surface (14, 15) for supporting curved pressurized diaphragms (9), characterized in that the bottom flange includes a connecting element (10) joining the two angled legs in such a way that said bottom flange has a closed cross-section. A structure such as this can advantageously be made of a composite material.
