Abstract
Formwork support comprising an outer support part and a telescopic inner support part, wherein the inner support part comprises a twist-proof portion and the outer support part comprises a twist-proof region with a first inner contour, wherein during telescoping of the inner support part, the twist-proof region of the outer support part cooperates with the twist-proof portion of the inner support part in such a manner that a twisting of the inner support part about its longitudinal axis with respect to the outer support part is blocked, wherein the outer support part comprises a guide region with a second inner contour which differs from the first inner contour for guiding the inner support part.
