<p>A formwork for use in the fabrication of shell constructions, especially superstructures and other buildings, e.g. with curved or doubly curved surfaces, comprises at least two frameworks (1) which are provided at a distance from each other, to which there is attached with releasable attachment elements an arrangement of preferably hollow, interlinked, longitudinal tubular ribs (5). Between the frameworks (1) on the formwork which is formed by the ribs (5) there is provided a sheet of fabric (3) which will form a part of the shell structure.</p> |
