The device has unevennesses (4, 4') (longitudinal grooves or ribs) on the flanges (2) of the profiles forming the vertical posts (1), with which unevennesses holding means, such as bolts, (6) or hooks (9), of the strut anchorages (5, 7) interact. As a result, holes in the post flanges are eliminated. <IMAGE> |
