Battery mold for the vertical production of flat prefabricated concrete parts

A battery formwork for the vertical manufacturing of planar precast concrete parts comprising two outer formworks, which are located diametrically opposite and at least one of which is movable, and an inner formwork, which is located between the outer formworks. The inner formwork has at least two side supports, which laterally delimit the concrete part to be manufactured. A floor support of the inner formwork is fixed in its location and delimits the concrete part to be manufactured on the bottom. The floor support is used as the lower reference point for the manufacturing of the precast concrete part. The battery formwork has a horizontally extending height support, which is vertically changeable in its position and which delimits the precast concrete part to be manufactured on top.
