ABSTRACT:
A formwork system comprises an outer formwork, an inner formwork and an opening box-out. The opening box-out is rigidly connected to the outer formwork. The opening box-out can be reduced or enlarged in size by hinging a movable frame to its rigid inner frame. In the erected state of the formwork system, the opening box-out projects into an opening of the inner formwork. The opening of the inner formwork corresponds to the size of the recess to be formed on a concrete body. The inventive formwork system permits concreting of different wall thicknesses without changing the formwork system. Fitting of the opening box-out into a double-headed formwork can be omitted. Recess sizes and contours can be made more exact since the adjustable opening box-out is pressed on the inner edge of the opening in the second formwork shell.
