Abstract

The present invention relates to a formwork system (1) comprising a form lining (2) and at least one shaped element (10) which is attached to the rear side (4) of the form lining (2). The form lining (2) and the shaped element (10) have been produced by a 3D printing method. This is preferably carried out in a common 3D printing process, but the form lining (2) and the shaped element (10) can also be produced in separate 3D printing processes, with the shaped element (10) then being attached to the rear side (4) of the form lining (2). This is effected using at least one first fastening element (50). If, by contrast, the form lining (2) and the shaped element (10) have been produced in a common 3D printing process, the additional use of a first fastening element (50) for fastening the shaped element (10) to the form lining (2) is not required. According to the invention, the shaped element (10) and optionally the first fastening element (50) are attached to the rear side (4) of the form lining (2) in such a way that they do not touch or pierce the front side (3) of the form lining (2). The present invention also relates to the use of such a formwork system (1), for example in the production of structural elements made of concrete.

First claim

The invention claimed is:

1. A formwork system ( 1 ) for the production of structural elements made of concrete comprising
a form lining ( 2 ) which has a front side ( 3 ) and a rear side ( 4 ),
at least one shaped element ( 10 ) which is attached to the rear side ( 4 ) of the form lining ( 2 ),
wherein i) the form lining ( 2 ) and the shaped element ( 10 ) have been produced by a 3D printing method, ii) the shaped element ( 10 ) is attached to the rear side ( 4 ) of the form lining ( 2 ) optionally using at least one first fastening element, and iii) the shaped element ( 10 ) and optionally the first fastening element are attached to the rear side ( 4 ) of the formwork lining ( 2 ) in such a way that the shaped element ( 10 ) and the optionally used first fastening element do not touch or pierce the front side ( 3 ) of the form lining ( 2 ), wherein the formwork system ( 1 ) is fastened to at least one subregion of a substructure ( 30 ) using at least one second fastening element, wherein the substructure ( 30 ) is completely produced from wood, wherein
the at least one shaped element ( 10 ) has at least one opening ( 11 ), in the form of a round hole or a slot, and at least one first second fastening element, in the form of a wire ( 21 ), a cable or a steel strip, is inserted, by way of one subregion thereof, into the opening ( 11 ) or partially pulled through, and the first second fastening element is fastened, by way of another subregion thereof, to the substructure ( 3 0 ) using at least one second second fastening element, selected from the group consisting of a screw or a nail.

2. The formwork system ( 1 ) according to claim 1 , wherein the form lining ( 2 ) and the at least one shaped element ( 10 ) have been produced in a 3D printing process.

3. The formwork system ( 1 ) according to claim 1 , wherein the form lining ( 2 ) and the at least one shaped element ( 10 ) have each been produced in separate 3D printing processes, and the shaped element ( 10 ) is then attached to the rear side ( 4 ) of the form lining ( 2 ) using at least one first fastening element.

4. The formwork system ( 1 ) according to claim 3 , wherein the at least one shaped element ( 10 ) is attached to the rear side ( 4 ) of the form lining ( 2 ) by adhesive bonding, screwing, nailing and/or riveting, and/or, as first fastening element, adhesive, screws, nails and/or rivets are used.

5. The formwork system ( 1 ) according to claim 1 , wherein the at least one shaped element ( 10 )
i) has at least one opening ( 11 ), in the form of a round hole, a slot or a cutout, or
ii) has at least one latching lug ( 13 ), or
iii) has at least one reinforcing rib ( 12 ).

6. The formwork system ( 1 ) according to claim 1 , wherein the substructure ( 30 ) is a wooden lattice construction or a cleat construction.

7. A method comprising utilizing the formwork system ( 1 ) according to claim 1 in concrete construction or for the production of structural elements made of concrete, wherein the front side ( 3 ) of the form lining ( 2 ) is the side of the formwork system ( 1 ) facing the concrete.
