The wall has vertical profiled uprights (1), which each have a wall skin (2) on both sides. The skins are attached using only self-tapping screws, which each pass first through a plaster panel, and then through a layer of sheet steel.Each wall skin has a second sheet steel layer (6) which is separated from the first (4) by plaster slabs (3,5), and whose external side can be also be covered by plaster (7). The layer is formed from sheet steel panels whose thickness is not greater than 1.5 mm, and which have overlapping joints (8). Each layer has a separate group of fastening screws (9,10,11).Both sheet steel layers of each wall skin may have a thickness of between 0.4 and 1.0 mm |
