Abstract
Apparatus () for vertical () slip forming of concrete walls and columns (). The apparatus comprises an attachment portion () for a frame with a slipform assembly inside comprising an extrusion form providing side walls defining a cavity and actuators () to adjust the position of the side walls forms essentially arranged along the longitudinal axis of the slipform assembly. A concrete supply () is connected with the slipform assembly for delivering concrete () to that cavity through the top open surface. A mechanism () is provided for vertically displacing () that slipform assembly incrementally relative to the frame. Thus, a concrete structure () having a vertical orientation is continuously cast. The actuators () adjust the position of the side walls during the incremental vertical movement () of the slipform assembly to create new forms for a column or wall with variable diameter, variable form and/or twisted.
