Abstract: The invention relates to a sliding shuttering system for producing concrete structure walls, particularly for conical and/or sloping reinforced concrete structures with annularly closed, varying cross-sections. Especially in the case of sloping structures with upwardly diverging wall regions, the hitherto known sliding shuttering systems can only be used to a limited extent with regards stability and security. In order to be able to perform a sliding process even in the case of extreme structure configurations, the support is made rigid and is mounted on angularly adjustable piles, at least one of the pairwise associated piles being fixed to the support to prevent horizontal shifting.
