Formwork panel element and formwork system

Abstract

The invention relates to a formwork panel element for shuttering a curable building material, having a frame (2) and having a multilayer formwork skin (3) fastened to the frame (2). The formwork skin (3) has a support panel (4) and a rigid wear panel (5). The support panel (4) is fastened to the frame (2). The wear panel (5) is releasably fixed to the support panel (4). A front side (5a) of the wear panel (5) facing away from the support panel (4) is designed as a surface in contact with the building material. The support panel (4) is fastened to the frame (2) so that it is resistant to tensile stress and shearing, in such a way that the support panel (4) supports the frame (2) statically, the support panel (4) being connected to the frame (2) in a non-releasable manner, or in a manner allowing release under certain conditions.
