Abstract

A structural element ( 10 ) for use as a ceiling element or wall element. The structural element ( 10 ) has a facing shell ( 11 ) and a relatively thicker supporting shell ( 12 ). The facing shell ( 11 ) has a first concrete layer ( 14 ) with a textile reinforcement ( 15 ) arranged therein. The supporting shell ( 12 ) has a second concrete layer ( 16 ) and a supporting shell reinforcement ( 17 ) in the form of a box-grid structure from interconnected structural steel elements ( 18, 19, 20 ). The facing shell ( 11 ) is connected to the supporting shell ( 12 ) by a plurality of metal-free connecting bodies ( 24 ) in the form of a three-dimensional a textile grid structure ( 25 ). The textile grid structure can be produced as a woven fabric, a plait, a nonwoven fabric or a knit from carbon fibers and/or glass fiber threads that have a coating to produce the three-dimensional structure. Each connecting body ( 24 ) extends in at least two spatial planes.

First claim

The invention claimed is:

1. A structural element ( 10 ) comprising
a facing shell ( 11 ) having a first concrete layer ( 14 ) and a textile reinforcement ( 15 ),
a supporting shell ( 12 ) having a second concrete layer ( 16 ) and a supporting shell reinforcement ( 17 ),
a plurality of connecting bodies ( 24 ) arranged between the textile reinforcement ( 15 ) and the supporting shell reinforcement ( 17 ) and connected to the supporting shell ( 12 ) as well as to the facing shell ( 11 ), and
said connecting bodies ( 24 ) each having a three-dimensional textile grid structure ( 25 ), wherein each said connecting body ( 24 ) has at least two grid sections ( 27 , 28 , 29 ) which extend in different spatial planes.

2. The structural element ( 10 ) of claim 1 in which each said connecting body ( 24 ) is a bent textile grid.

3. The structural element ( 10 ) of claim 1 in which each said connecting body ( 24 ) has a first grid section ( 27 ) and a second grid section ( 28 ) which extend parallel to one another and a third grid section ( 29 ) which connects the first grid section ( 27 ) to the second grid section ( 28 ).

4. The structural element ( 10 ) of claim 3 in which two of said connecting bodies ( 24 ) are positioned with their respective third grid section ( 29 ) connected to one another.

5. The structural element ( 10 ) of claim 3 in which two of said connecting bodies ( 24 ) are connected to one another by a reinforcing element ( 36 ).

6. The structural element ( 10 ) of claim 5 in which a plurality of said connecting bodies ( 24 ) of a first group ( 45 ) extend in a longitudinal direction (L) continuously along the structural element ( 10 ).

7. The structural element ( 10 ) of claim 6 in which a plurality of said connecting bodies ( 24 ) of a second group ( 47 ) extend in a transverse direction (Q) transverse to the longitudinal direction (L) between the connecting bodies ( 24 ) of the first group ( 45 ).

8. The structural element ( 10 ) of claim 1 in which each said connecting body ( 24 ) extends parallel to an edge ( 46 , 48 ) of the structural element ( 10 ).

9. The structural element ( 10 ) of claim 1 in which the textile grid structure ( 25 ) is embodied as one of a knit, a woven fabric, a nonwoven fabric, a plait, or textile surfaces that are adhered to one another.

10. The structural element ( 10 ) of claim 1 in which said textile grid structure ( 25 ) includes glass.

11. The structural element ( 10 ) of claim 1 in which said textile grid structure ( 25 ) includes carbon fibers.

12. The structural element ( 10 ) of claim 1 in which the textile grid structure ( 25 ) of each connecting body ( 24 ) has a coating.

13. The structural element ( 10 ) of claim 1 in which the supporting shell reinforcement ( 17 ) consists of steel elements ( 18 , 19 , 20 ).

14. The structural element ( 10 ) of claim 1 in which the supporting shell reinforcement ( 17 ) consists of textile material.

15. The structural element ( 10 ) of claim 1 including an insulating layer ( 13 ) arranged between the supporting shell ( 12 ) and the facing shell ( 11 ).

16. The structural element of claim 1 in which said grid sections are formed with holes.

17. The structural element of claim 1 in which said grid sections are in the form of meshes.

18. A method for producing a structural element ( 10 ) comprising the steps of:
arranging a textile reinforcement ( 15 ) for a facing shell ( 11 ) of the structural element ( 10 ) on a formwork table ( 55 ),
connecting to the textile reinforcement ( 15 ) a plurality of connecting bodies ( 24 ) each having a three-dimensional textile grid structure ( 25 ), wherein each said connecting body ( 24 ) has at least two grid sections ( 27 , 28 , 29 ) which extend in different spatial planes,
pouring a first concrete layer ( 14 ),
providing an insulating layer ( 13 ) between the connecting bodies ( 24 ) on the first concrete layer ( 14 ),
arranging a supporting shell reinforcement ( 17 ) on said insulating layer ( 13 ),
pouring a second concrete layer ( 16 ), and
hardening the two concrete layers ( 14 , 16 ).
