Abstract
Apparatus (10) for vertical (72) slip forming of concrete walls and columns (55). The apparatus comprises an attachment portion (23) for a frame with a slipform assembly inside comprising an extrusion form providing side walls defining a cavity and actuators (20) to adjust the position of the side walls forms essentially arranged along the longitudinal axis of the slipform assembly. A concrete supply (45) is connected with the slipform assembly for delivering concrete (52, 53, 54) to that cavity through the top open surface. A mechanism (20) is provided for vertically displacing (72) that slipform assembly incrementally relative to the frame. Thus, a concrete structure (55) having a vertical orientation is continuously cast. The actuators (20) adjust the position of the side walls during the incremental vertical movement (72) of the slipform assembly to create new forms for a column or wall with variable diameter, variable form and/or twisted.
