<p>The present invention relates to a cellular floor structure comprising two skin plates (1) spaced at a distance from each other and connected to each other by a sheet structure (2, 4) herein called a waist web plate. According to the invention, the skin plate (1) is curved over at least one area toward the waist web structure (2, 4) and the waist web structure (2, 4) is formed so as to support the skin plate (1) in a direction perpendicular to the skin plate surface and in at least one direction orthogonal to the edge (7) of the curved area. Most advantageously, the skin plate is curved in the form of a catenary. <IMAGE></p> |
