Claims20
A roof construction, comprising:
- at least one corrugated construction having two identical longitudinally extended elements, namely a top one of said elements forming a ridge and a bottom one of said elements forming a trough, that are directly connected to each other at their respective longitudinal edges near a neutral line of said corrugated construction,
- wherein each of said top and bottom elements comprises a sandwich construction with an outer skin, a filling, an inner skin, and reinforcing connections at longitudinal edges that connect said inner skin and said outer skin to each other, and
- wherein said corrugated construction is at least fifteen meters long and is substantially rigid when supported only at its longitudinal ends.
A roof construction, comprising:
- at least one corrugated construction having two identical longitudinally extended elements, namely a top one of said elements forming a ridge and a bottom one of said elements forming a trough, that are directly connected to each other at their respective longitudinal edges near a neutral line of said corrugated construction,
- wherein each of said top and bottom elements comprises a sandwich construction with an outer skin, a filling, an inner skin, and tongue and groove reinforcing connections at longitudinal edges that connect said inner skin and said outer skin to each other, said reinforcing connections each comprising a reinforcing, thermally insulating material between said inner and outer skins that extends laterally to a distance greater than said groove.
