| 摘要 |
The invention proposes producing curved double-walled and multi-walled ribbed panels by extrusion, the curvature of the panel being produced as early as during the production process, the axis of curvature of the panel then running parallel to the longitudinal extent of the ribs. The invention further proposes, simultaneously with the production process of the panels, forming profiles at the edges or on the surfaces of the panels which serve to join the panels to one another or to connect further construction parts.
