The invention relates to a flange for a self-supporting rigid hollow body having large dimensions and intended for building constructions, to a method for making such a hollow body using such flanges, and to equipment for implementing said method. The rigid flange (6) is intended to be part of a self-supporting rigid hollow body having large dimensions and intended for building constructions, of the type comprising a thin wall (4) having a generally cylindrical shape relative to an axis, made of a coating and resistance material containing concrete or the like and reinforced with fibres, and two such end flanges (6) oriented towards the outside, wherein said flange includes, on the hand, a main portion (9) generally in the shape of a flattened hollow cylinder to be visible in the body upon completion and, on the other hand, a talon (10) extending in an axial direction from a transverse face (11) of the main portion (9) and having inner radial overall dimensions equal to or close to the inner radial overall dimensions of the main portion (9), and outer radial overall dimensions lower than the outer radial overall dimensions of the main portion (9). |
