Roof construction having a roof skin (10) mounted on a base construction (14) and comprising a bottom skin (26) and a top skin (28) mounted above and spaced apart from the bottom skin (28), characterised in that
- the roof skin (20) has a two-dimensionally curved surface,
- the bottom skin (26) is supported on the base construction (14) via a grid (12) that is formed by plane plates (20, 22) oriented normal to the plane of the grid and crossing one another, top edges (24) of the plates being curved to define the curvature of the roof skin,
- the surface of the roof skin is divided into segments (34, 36) at least some of which are spanned by an associated set of straight lines (32), and
- the top skin (28) is held at a constant spacing from the bottom skin (26) by spacer profiles (42) extending along the straight lines (32). |
