An apparatus for forming a multisided upright concrete wall with inner and outer form set-ups including an arrangement for stripping said inner form set-up which has a multisided form wall from the cast concrete entirely which comprises at least one wedge means dividing at least one side of the form wall into two portions and wedged in between the two portions in a first direction during casting, and means for moving the wedge means in a second direction opposite to the first direction after casting and bringing the two portions to be nearer relative to one another, whereby the inner form set-up contracts and therefore entirely is spaced apart from the cast concrete. |
