<p>The invention relates to a method for forming a three-dimensional construction from a hollow sandwich panel (1), which consists of two boards (2) which are held at a mutual distance by spacer elements (3) extending mutually parallel and lying at a mutual distance, which method consists of reducing the bending stiffness of the sandwich panel (1) by reducing the stiffness of at least one of the boards, and bending the sandwich panel (1) round an axis of curvature such that in the area of the bending an inner board with relatively small radius of curvature and an outer board with relatively large radius of curvature are created, wherein according to the invention the bending stiffness of at least one of the boards is first reduced by deforming a part of the relevant board, and the sandwich panel (1) is subsequently bent round the axis of curvature formed by the deformed board part, and wherein the axis of curvature can also be straight or curved.</p> |
