Abstract
Abstract A pair of sliding forms are supported by a yoke, at least one of the sliding forms being supported for movement in a horizontal direction. A climbing rod is adapted to be gradually imbedded in the erected concrete structure, and lifting means is operatively associated with the climbing rod for lifting the yoke along the climbing rod. Wedge means is mounted on the climbing rod and cooperates with a portion of the yoke for moving at least one of the sliding forms in a horizontal direction upon lifting the yoke along the associated climbing rod.
