Abstract
Roof construction having a roof skin mounted on a base construction and including a bottom skin and a top skin mounted above and spaced apart from the bottom skin, the roof skin having a two-dimensionally curved surface, the bottom skin being supported on the base construction via a grid that is formed by plane plates oriented normal to the plane of the grid and crossing one another, top edges of the plates being curved to define the 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, and the top skin is held at a constant spacing from the bottom skin by spacer profiles extending along the straight lines.

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.
Roof construction comprising:
- a base construction,
- a grid formed by first plates extending in a first direction and second plates extending in a second direction which is at an angle to the first direction, with the first plates crossing the second plates at multiple locations, and with top edges of both the first and second plates being curved to define a curvature of the grid in said first and second directions,
- a roof skin mounted on the grid so as to follow the curvature of the grid in said first and second directions, the roof skin extending in a direction normal to the top edges of the plates and comprising a bottom skin, a top skin mounted above and spaced apart from the bottom skin and spacer profiles which hold the top skin at a constant spacing from the bottom skin, and
- the roof skin being divided into segments, at least some of which are spanned by an associated set of straight lines extending in three dimensions, with each straight line disposed at at least one varying angle with respect to both said first and second plates.
