Abstract: 1. Construction with a flexible cover at least the portion of which forming the roof (2) is defined by a three-dimensional metal or composite framework (3) made of metal or composite material and comprised of a basic structure (4) or a juxtaposition of several of these latter, each of which includes at least two parallel longitudinal beams (5, 6) connected by means of cross-beams (8) and from which extend diagonal beams (9, 9A, 9B, 9C) defining, as the case may be, at least two girders (Fl, E2) made integral by their top (S) and forming a module (Ml), or even one or a series of pyramidally-shaped modules (M, Ml, M2, M3), in the inner space delimited by each of these basic structures (4) being subtended at least one flexible cover (7) of the type with a double curvature, characterised in that: - both parallel longitudinal beams (5, 6) of a basic structure (4) are each defined by a profile bar (10) including at least a through-groove (11A, 11B) for receiving a retaining strip (12) provided for at two longitudinal edges (13, 14) of the flexible cover or covers (7) with a double curvature aimed at being subtended at the level of said basic structure (4); - and that such a profile bar (10) is provided with means (15) for receiving the ends (16, 16A) of the diagonal beams (9, 9A, 9B, 9C) and/or of the cross-beams (8), with a view to their fixing. 2. Construction according to claim 1, characterised in that a profile bar (10) aimed at defining a longitudinal beam (5, 6) is made symmetrical with respect to a vertical plane of symmetry (17) and includes two through-grooves (11A, 11B) for receiving a retaining strip (12) provided for at the longitudinal edge (13, 14), respectively, of the flexible covers with a double curvature (7) corresponding to two juxtaposed basic structures (4). 3. Construction according to claim 2, characterised in that a profile bar (10) aimed at forming a longitudinal beam (5, 6) includes a second pair of grooves (20A, 20B) arranged at a level substantially lower than the grooves (11A, 11B) for receiving the retaining strip corresponding to a lining canvas of juxtaposed basic structures (4). 4. Construction according to any of the preceding claims, characterised in that the means (15) for receiving the ends (16; 16A) of the diagonal beams (9, 9A, 9B, 9C) and/or the cross-beams (8) are in the shape of lugs (30, 30A) inserted, viz. equidistantly, on said profile bar (10). 5. Construction according to claim 4, characterised in that the lugs extend from a profile bar (10) according to an angle of inclination (19) adapted to the orientation to be imparted to the diagonal beam or beams (9, 9A, 9B, 9C) and/or to the cross-beams (8). 6. Construction according to any of claims 4 or 5, characterised in the lugs (18, 18A) are inserted, viz. by welding and alongside generating lines, on a joining part (31) with an outer cross-section (32) adjusted to the inner cross-section (33) of the profile bar (10) of a tubular type and defined by one or several profile bar lengths (10A, 10B) at the ends (34A, 34B) of which are inserted such joining parts (31). 7. Construction according to claim 6, characterised in that the ends (34A, 34B) of the profile bar length or lengths (10A, 10B) are axially notched for the passing through of the lugs (30, 30A) and for ensuring the continuity at the level of the joining of two profile bar lengths (10A, 10B). 8. Construction according to any of claims 1 to 3, characterised in that the means (15) for receiving the ends (16; 16A) of the diagonal beams (9, 9A, 9B, 9C) and/or of the cross-beams (8) are in the shape of one or several wings (19; 19A) and/or of wing lengths radially extending at the periphery of the profile bar (10). 9. Construction according to claim 2 and any of claims 4 through 8, characterised in that the means (15) for receiving the ends (16; 16A), as the case may be, of the diagonal beams (9, 9A, 9B, 9C) or of the cross-beams (8) adopt a symmetrical configuration with respect to the vertical plane of symmetry (17) around the profile bar (10). 10. Construction according to any of the preceding claims, characterised in that a profile bar (10) defining a longitudinal beam (5, 6) is foreseen of the tubular type, its inner portion being capable of forming a gutter capable of collecting and evacuating running water coming from the covers with a double curvature (7). 11. Construction according to any of claims 1 through 9, characterised in that a profile bar (10) aimed at forming a longitudinal beam (5, 6) is provided, directly or through connecting lugs (21A, 21B), with a pair of grooves (22A, 22B) for receiving the retaining strips of a water-proof canvas (23) capable of extending in the shape of a gutter under such a profile bar (10). 12. Construction according to any of the preceding claims, characterised in that a basic structure (4) includes at least a third longitudinal beam (25) defined by a profile bar (10') and including means (15) for receiving, with a view to the fixing, diagonal beams (9, 9A, 9B, 9C) and/or cross-beams (8A), such a longitudinal beam (25) connecting to each other the tops (S; 24) either of several girders (Fl. F2) defined by the diagonal beams (9, 9A, 9B, 9C) or of several modules (M\ M, Ml, M2, M3) corresponding to one and the same basic structure (4) or to several juxtaposed basic structures (4). 13. Construction according to claim 12, characterised in that the profile bar (10') defining the longitudinal beam (25) includes one or several grooves for receiving retaining strips corresponding to a canvas, viz. a netting, capable of being stretched over the flexible covers with a double curvature. (7). 14. Construction according to claims 12 or 13, characterised in that the profile bar (10') defining a longitudinal beam (25) is, in its lower portion (36), configured in the shape of a rail (37) for receiving one or several slides to which are capable of being fixed one or several cables (38) for tensioning the cover or covers with a double curvature (7).
