<p>The subframe (210) has a lower cross-piece, an upper cross-piece (214), and two uprights (216), where each of the uprights is fixed at the lower cross-piece and the upper cross-piece, so as to form a rectangular frame. The thickness of the upper cross-piece is reduced relative to the thickness of the uprights, so as to provide a passage (224) between the uprights and the upper cross-piece. The upper cross-piece is located on a side intended to be directed towards the outside or interior of a building. Independent claims are also included for the following: (1) an assembly of a subframe and a block of roller-shutter (2) a wall of a building.</p> |
