A wall construction which is made up of at minimum two shell elements (1) having a surface sheet portion (2) and at opposite edges edge portions (3), as well as any necessary filling (4a, 4b) in the space delimited by these, and of fasteners (5) comprising a web portion (6) and, protruding from it in a direction parallel to the surface sheet, a transverse branch (7) or branches, which engage a groove or perforations in the edge portion of the shell element. In the wall construction the said two shell elements (1) are located adjacently in the direction of the wall thickness (T), as a combination (11), and the fasteners (5) have projecting branches (7, 8) at least at two different depths of the web portion (6), at the first depth to engage a groove (10) or a perforation in the first shell element (1') and at the second depth to engage a groove (10) or perforation in the second element (1"), and the fasteners (5) are within the thickness (T) of the shell element combination (11), in order to produce a wall without a separate frame. |
