Wall for interior architecture

1. A wall for interior architecture, in particular for partitioning adjacent rooms, comprising:

a substantially rigid frame defining an external perimeter surface of the wall; and

one pair of opposite faces provided on lateral sides of said wall, said opposite faces being constrained to said rigid frame and made of a flexible material,

wherein said rigid frame defines a first and a second groove on said lateral sides of said wall, said first and second groove being configured to engage constraining portions of said opposite faces, and

wherein said constraining portions maintain said opposite faces tensioned and substantially parallel to a geometrical plane, said rigid frame and said opposite tensioned faces delimiting an internal hollow region.

2. The wall according to claim 1 , wherein said rigid frame further defines a flat surface on said external perimeter surface of said wall, said flat surface having a third groove defined therein and configured to receive a joining member disposed between said wall and an adjacent wall.

3. The wall according to claim 1 , wherein said constraining portions are elastic and comprise an edge integral with a perimeter of each of said opposite faces and configured to be pressure-fitted into the first or the second groove.

4. The wall according to claim 3 , wherein each one of said opposite faces is made of a stretch fabric or a fabric comprising elastic fibers, and wherein the edge of each one of said opposite faces is fixed to an enlarged linear element configured to be pressure-fitted into the first or the second groove.

5. The wall according to claim 3 , wherein said first and said second groove are parallel to said geometrical plane.

6. The wall according to claim 3 , wherein said first and said second groove are substantially at opposite corners at a level of said external perimeter surface.

7. The wall according to claim 3 , wherein said edge is provided with an enlarged portion substantially along an external length of said edge.

8. The wall according to claim 1 , further comprising internal reinforcing section bars positioned in said internal hollow region.

9. The wall according to claim 8 , wherein said rigid frame comprises a plurality of perimeter section bars, further comprising releasable devices that selectively constrain said internal reinforcing section bars to said perimeter section bars.

10. The wall according to claim 9 , wherein said perimeter section bars and said internal reinforcing section bars are in aluminum alloy.

11. The wall according to claim 1 , wherein said flexible material of said opposite faces is a fabric having one or more layers.

12. The wall according to claim 1 , wherein said flexible material of said opposite faces is a Jacquard fabric.

13. The wall according to claim 1 , wherein said flexible material of said opposite faces is a Jacquard fabric having different weft or warp yarn color or thickness.

14. The wall according to claim 1 , wherein said flexible material of said opposite faces is a Jacquard fabric having different colors or designs on two sides of the Jacquard fabric.

15. The wall according to claim 1 , wherein said flexible material of said opposite faces is a fabric adapted for printing or embroidering.

16. The wall according to claim 1 , wherein said flexible material of said opposite faces is polyester.

17. The wall according to claim 1 , wherein said flexible material of said opposite faces has a basis weight of 300 g/m 2 .

18. The wall according to claim 9 , further comprising one or more stiffening crosspieces, made integral with said perimeter section bars of the frame for supporting lighting equipment, pictures, and any other item to be hung on the wall.
