摘要

A process for preparing a formwork element for a concrete formwork, in particular inner tunnel-lining sheathing, by means of clamping at least one first blank (6) made of a sheet-like form auxiliary material to a formwork surface or - skin (5) of the formwork element (3), wherein the at least one blank on the formwork surface (5) is placed in such a way that the formwork auxiliary material surrounds the formwork element (3) and two ends (6 '') of the of the at least one cutout formwork auxiliary material adjacent to one another, but are spaced apart on the formwork surface (5) are provided, at the ends (6'') which connect these to one another, clamping devices (8), and is mounted by means of this the formwork auxiliary material on the formwork element (3) by clamping the ends (6 '') is tensioned,characterized by the,that after the tensioning of the ends (6 '') by means of connecting elements (13) are connected to one another,that, after the attachment of the connecting elements (13) the clamping devices (8) be loosened and removed, andthat, after the attachment of the connecting elements (13) and the release of the clamping devices (8) at least a second, the clamping region between the ends (6 '') and the connecting elements (13) and which bridges blank (14) from the formwork auxiliary material is applied.
