Abstract:
The invention relates to a rigid self-supporting hollow body (1) having large dimensions and intended for building constructions, wherein said body is of the type comprising a thin wall (4) having a generally cylindrical shape relative to an axis (5) and two end flanges (6) oriented towards the outside, defining an integral assembly having an inner hollow space (7) with two end openings (8), made of a coating and resistance material containing concrete or the like and reinforced with fibres. The flanges (6) include or define fastening means (15) that enables, using fastening members (6), the rigid fastening on one and/or the other flanges (6) of the body, of an adjacent flange (6) of a second similar neighbouring body (1) and/or of a blocking wall (3) optionally comprising one or more openings (3a) so as to build constructions in a modular and flexible manner.
Abstract:
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).
