<p>A prefabricated roof plate element (4), including one or more longitudinal box-shaped girders (24), each consisting of two predominantly U-shaped metal sections (10, 18) which at mutually facing, open sides are interconnected along narrow outwards bent lateral edges (5), the girders (24) being connected at upper and lower narrow sides corrugated in longitudinal direction with corrugated metal plates (7) corrugated in transverse direction and having approximately the same width as the roof plate element (4), the girders (24) being disposed along opposing sides and at the centre of the roof plate element (4), where the girders (4) and the roof plate element (4), respectively, are designed with reduced height/thickness at an end part intended for forming eaves (6). By means of simple technical measures is hereby achieved substantial projecting advantages which furthermore have appeared, to enable an architecturally very simple and light construction of the visible part of the roof plate on buildings.</p> |
