The invention concerns a false wall formed by a matrix of caissons (20, 22, 22') each consisting of a frame whereon a fabric (12) is stretched. Said false wall is characterised in that each of the sides (23) of the frame consists of a rigid masked rail element, and it comprises means (32, 33) capable of associating in parallel, with a given spacing (<u>e</u>), two adjacent sides (23) of two neighbouring caissons (20, 22, 22'). |
