Connecting profile for connecting sheet piles to carrier elements and combined sheet pile wall comprising such a connecting profile

1. A connecting profile, which has a constant cross section and is intended for coupling sheet piles to carrier elements, in particular for building a combined sheet pile wall comprising:

sheet piles and carrier elements, like double T-shaped carriers;

the connecting profile exhibiting a center strip, a coupling profile, which is to be connected to the carrier element and which is formed on the first side of the center strip, and an interlock profile for hooking an interlock of the sheet pile, the interlock profile being formed on a second side of the center strip that faces way from the first side of the center strip;

the interlock profile exhibiting a straight supporting strip, which projects from the center strip, and a hook strip, which projects from the center strip;

wherein the straight supporting strip of the interlock profile projects at least approximately at a right angle from the second side of the center strip; and

wherein the hook strip exhibits a straight transition section, which projects at least approximately at a right angle from the second side of the center strip and which bends over into a straight hook section which runs at least approximately at a right angle to the transition section in the direction of the supporting strip and the end of which defines, with the end of the supporting strip, a jaw for inserting the interlock of the sheet pile, the jaw being arranged opposite to the second side of the center strip.

2. The connecting profile as recited in claim 1 , further comprising an inside, which belongs to the center strip and is defined by the interlock profile, and wherein the inside is flattened off and forms jointly with the supporting strip and the hook strip an interlock inner chamber, which is at least approximately rectangular as viewed in the cross section.

3. The connecting profile as recited in claim 1 , wherein the supporting strip terminates in a plane, which runs tangentially to an outwardly facing flat side of the hook section.

4. The connecting profile as recited in claim 1 , wherein the supporting strip exhibits an end section, which runs at least approximately at a right angle to the supporting strip and points in the direction of the hook strip.

5. The connecting profile as recited in claim 4 , characterized in that the end section of the supporting strip and the hook section of the hook strip lie with their outwardly facing flat sides in a common plane.

6. The connecting profile as recited in claim 1 , wherein a maximum distance between an inner surface of the supporting strip and an inner surface of the transition section of the hook strip is greater than a second distance between a flat side of the center strip and an inner surface of the hook section of the hook strip.

7. The connecting profile as recited in claim 6 , wherein the ratio between the maximum and second distances is in a range of 1.8 to 1 up to and including 1.2 to 1.

8. The connecting profile as recited in claim 1 , wherein the interlock profile is dimensioned so as to accommodate an interlock of a LARSSEN sheet pile or a HOESCH sheet pile, which is to be connected.

9. The connecting profile as recited in claim 1 , wherein the coupling profile is defined by the center strip; a first straight jaw, which projects from the first side of the center strip and faces away from the interlock profile at an angle of 90 degrees and a second jaw, which is bent off in the direction of the first straight jaw and which extends from the first side of the center strip and which is spaced apart from the first jaw.

10. The connecting profile as recited in claim 9 , wherein the bent off second jaw of the coupling profile and the supporting strip of the interlock profile are formed directly adjacent to each other on the center strip, and wherein the bent off second jaw and the supporting strip each have an outer flat side, the outer flat side of the second jaw and the outer flat side of the supporting strip passing over into each other.

11. The connecting profile as recited in claim 9 , wherein the bent off second jaw of the coupling profile and the transition section of the hook strip are formed directly adjacent to each other on the center strip.

12. The connecting profile as recited in claim 1 , wherein the coupling profile exhibits two jaws, which run at least approximately parallel to each other and project from the first side of the center strip and between which the carrier element is to be inserted with a fastening section for fastening.

13. Connecting profile, as claimed in claim 9 , wherein the coupling profile is offset, as viewed in the cross section of the connecting profile, on the center strip in such a manner in relation to the interlock profile that one of the two jaws is offset outwardly in relation to the transition section of the hook strip.

14. The connecting profile as recited in claim 1 , wherein the coupling profile is designed for welding to the carrier element.

15. The connecting profile as recited in claim 1 , wherein the connecting profile is produced by rolling.

16. A combined sheet pile wall comprising:

a plurality of carrier elements, in particular double T-shaped carriers;

at least one sheet pile, which is inserted between two of the carrier elements;

a connecting profile which is disposed between said carrier elements and said sheet pile, wherein the connecting profile connects together the carrier elements and the sheet pile;

an interlock profile, which engages with an interlock, that is formed on the sheet pile;

a receiving profile, that is coupled to a fastening section of one of the carrier elements are formed;

the connecting profile having a center strip, wherein on a first side of the center strip, the receiving profile is formed and wherein on a second side of the center strip that faces away from the first side the interlock profile is formed;

wherein the interlock profile exhibiting a supporting strip, which projects from the center strip, and a hook strip, which projects from the center strip;

wherein the straight supporting strip of the interlock profile projects at least approximately at a right angle from the second side of the center strip; and

wherein the hook strip exhibits a straight transition section, which projects at least approximately at a right angle from the second side of the center strip; and which bends over into a straight hook section which runs at least approximately at a right angle to the transition section in the direction of the supporting strip and the end of which defines with the end of the supporting strip a jaw for inserting the interlock of the sheet pile, the jaw being arranged opposite to the second side of the center strip.

17. The combined sheet pile wall as recited in claim 16 , wherein the interlock, which belongs to the sheet pile and which engages with the connecting profile, is a LARSSEN interlock.

18. The combined sheet pile wall as recited in claim 16 , wherein the interlock, which belongs to the sheet pile and which engages with the connecting profile, is a HOESCH claw or a HOESCH knob.
