Abstract (en)

[origin: CA3016992A1] The invention relates to a method for producing hollow concrete elements with the following steps, especially in a circulating method: a) preparing of a pallet (15), b) placing of formwork elements (16, 17) on the pallet (15), c) transporting of the pallet (15) to a reinforcing station (5), where tensioning wires (19) are inserted into the space defined by the pallet (15) and the formwork elements (16, 17) and pretensioned, d) transporting of the pallet (15) to a concreting station (7), where at least one layer of concrete is poured into the space defined by the pallet (15) and the formwork elements (16, 17), e) introducing of core elements (21) into the space defined by the pallet (15) and the formwork elements (16, 17), f) pouring of at least one further layer of concrete into the space defined by the pallet (15) and the formwork elements (16, 17), transporting of the pallet (15) to a curing station (11), where the concrete is cured, and h) transporting of the pallet (15) to a destressing station (13), where the tensioning wires (19) are unstressed, especially at the same time. Further, the invention relates to a layout for producing hollow concrete elements.
