FLANGE FOR SELF-SUPPORTING RIGID HOLLOW BODY, METHOD FOR MAKING SUCH A HOLLOW BODY USING SUCH FLANGES, AND EQUIPMENT FOR IMPLEMENTING SAID METHOD

摘要

A flange (6) intended to be part of a self-supporting rigid hollow body having large dimensions and intended for building constructions, including 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. The flange includes a main portion (9) generally shaped as a flattened hollow cylinder and visible in the body upon completion and a talon (10) extending in an axial direction from a transverse face (11) of the main portion and having inner radial overall dimensions equal to or close to the inner radial overall dimensions of the main portion, and outer radial overall dimensions lower than the outer radial overall dimensions of the main portion. A method and equipment for making such a hollow body using such flanges are also described.
