The disclosure relates to a formwork device, in particular for arrangement between two bulkhead partitions of a battery mould, for manufacturing construction elements, in particular precast concrete elements, said formwork device comprising two formwork elements which each have a formwork front side for applying concrete and a formwork rear side, wherein the formwork elements are pivotably connected to one another at first end regions so that the formwork elements can be transferred from a vertical state into a horizontal state. The formwork device also comprises a spreading device for spreading apart second end regions of the formwork elements starting from the vertical state of the formwork elements, said second end regions being opposite the articulated connection. The disclosure also relates to: a battery mould comprising two bulkhead partitions and a formwork device according to the disclosure; a method for manufacturing a precast concrete element with the aid of the formwork device according to the disclosure; and a method for preparing the manufacture of a precast concrete element with the aid of the formwork device according to the disclosure.

A sub-base; an inner mold positioned on the sub-base; a pallet positioned around the inner mold and adjustable along the inner mold; and an adjustable magnetic support stand for supporting the pallet around the inner mold and positioned on the sub-base.

A mold apparatus comprising: a mold main body which can be coupled to at least one mold portion for shaping at least portions of a cast component, at least two magnet devices which each can be transferred between an interaction position in which they are designed to be magnetically operatively connected to a mold support and to fix the position of the main mold body on the mold support, and a release position in which the magnetic operative connection is reduced and the mold main body can be positioned with respect to the mold support. The mold apparatus also comprises an activation device by which the at least two magnet devices can be transferred at least from the interaction position into the release position at least temporarily with a time offset.

A sub-base; an inner mold positioned on the sub-base; a pallet positioned around the inner mold and adjustable along the inner mold; and an adjustable magnetic support stand for supporting the pallet around the inner mold and positioned on the sub-base.

A sub-base; an inner mold positioned on the sub-base; a pallet positioned around the inner mold and adjustable along the inner mold; and an adjustable magnetic support stand for supporting the pallet around the inner mold and positioned on the sub-base.
