Abstract: A method for forming a double-curved panel from a flat panel, which comprises processing a plastically deformable flat panel or rendering the flat panel plastically deformable to enable it to mould itself to a predetermined shape, wherein the shape is obtained by a primary supporting construction cooperating with a secondary supporting construction, wherein the primary supporting construction may or may not be adjustable to an invariant position that determines the shape, and the secondary supporting construction is adjustable between a starting position in which it supports the flat panel, and a finishing position in which the secondary supporting construction supports the double-curved panel, while said supporting construction rests on and is shaped in accordance with the shape of the primary supporting construction, wherein the adjustment from the starting position to the finishing position occurs at least subject to the distribution of the gravitational force exerted on the secondary supporting constructi

Abstract: The invention relates to a fixing device for fixing at least one facing panel (4) to a building. The fixing device comprises at least one frame section (2) which can form part of a framework (1) to be fitted around the facing panel (4). The fixing device also has at least one supporting part (10) for fixing to a floor, ceiling or partitioning wall of a building. The at least one frame section (2) and at least one supporting part (10) can be interconnected by connecting means (11), which permit pivoting of the supporting part (10) relative to the frame section (2) during fitting of the frame section (2) on the building, in such a way that the facing panel (4) can be fixed to the floor, the ceiling or the partitioning wall at an oblique angle relative to the plane of the floor, the ceiling or the partitioning wall respectively. The connecting means (11) can comprise a ball hinge or line hinge.
