Abstract:
1. Roof construction comprising: a base construction, a roof skin mounted on the base construction and comprising a bottom skin and a top skin mounted above and spaced apart from the bottom skin, and the roof skin a two-dimensionally curved surface which is a surface curved in two mutually orthogonal directions and in which, for any given direction, there is a curvature along some portion of the curved surface, a grid which supports the bottom skin on the base construction, the grid extending in a plane and the grid formed by plane plates oriented normal to the plane of the grid and crossing one another, with top edges of the plates being curved to define a curvature of the roof skin, the surface of the roof skin being divided into segments, at least some of which are spanned by an associated set of straight lines in three dimensions, with at least some of said straight lines being disposed at at least one varying angle with respect to other ones of said straight lines, and spacer profiles which hold the top skin at a constant spacing from the bottom skin, the spacer profiles extending along the straight lines.
