Climbing formwork device for a shaft

Abstract

A climbing formwork device for a shaft-shaped component comprises a central formwork carrier means, which carries at least four formwork parts on its circumference to form an inner formwork. The formwork carrier means has a lifting means to move anchoring formwork parts, which face away from one another, relative to the formwork carrier means and relative to the other formwork parts in the lifting direction. The formwork carrier means is furthermore formed to move all formwork parts to a retracted lifting position and a formwork position. The anchoring formwork parts have at least two securing appendages, which project from the formwork plane of the formwork parts for vertically securing the climbing formwork device in the shaft wall. The securing appendages are spaced apart from one another in the lifting direction by a lift of the lifting means, and a distance between the securing appendages can be set.
