Abstract

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.

Dependent claims

A formwork device, for a manufacture of construction elements, comprising:

two formwork elements, each of which comprises a formwork front side for concrete to be applied, and a formwork rear side, wherein the formwork elements are pivotably connected to each other at first end regions so that the formwork elements can be transferred from a standing state to a lying state, and a spreading device for spreading apart of second end regions of the formwork elements starting from the standing state of the formwork elements, said second end regions being opposite to the first end regions,
wherein the spreading device comprises a force deflection device engaging at the second end regions of the formwork elements, which force deflection device converts a lowering of the formwork elements into the spreading apart of the second end regions of the formwork elements,
wherein the force deflection device comprises two lever elements engaging at the second end regions of the formwork elements, and
wherein the two lever elements are connected to each other via a pivot bearing, with a pivot axis which is essentially stationary when spreading apart the formwork elements, wherein the pivot axis is essentially parallel to a pivot axis of the formwork elements.
