Planar element and method for producing a planar element

Abstract

In the present method for producing a planar element (2) for car bodies in differential construction, which includes an external skin (4) and at least one stiffening means implemented as planar, profiles (8) and profile nodes (10) being provided in a predetermined arrangement on the external skin (4), in a first step the stiffening means is glued to the external skin (4), in a second step profiles (8) and profile nodes (10) are arranged and joined into a frame, at least partially using a cold joining method, and in a third step the frame is joined to the external skin (4) on the side of the stiffening means, at least partially using a cold joining method. High planar buckling resistance of the plate panels is achieved through these measures.
