Barrier element and support structure for use in a barrier element

1. A barrier element for bounding a carriageway, comprising:

an elongated casing, comprising two opposing longitudinal side walls and an upper wall joining the two side walls; and

at least one casing support structure located in the elongate casing and connecting to both the side walls;

wherein at least one of the side walls of the casing is connected to the support structure at least at two spaced apart locations, such that between the at least two spaced apart connection locations of the support structure and the side wall, the support structure and the side wall are situated at a distance of each other, leaving a mutual transposition space,

wherein at least one of the side walls is provided with at least one indentation, elongated in the direction of elongation of the casing and projecting towards the support structure, and

wherein the support structure is at a side facing one of the side walls provided with at least one indentation projecting away from said side wall to contact and form an abutment with the indentation provided in said side wall.

2. A barrier element according to claim 1 , characterised in that the distance between the support structure and the side wall providing the mutual transposition space is at least 4 mm.

3. A barrier element according to claim 1 , characterised in that the spaced apart connection locations of the support structure and the side wall are separated in a plane perpendicular to the longitudinal direction of the casing.

4. A support structure for use in a barrier element according to claim 1 .

5. A barrier element according to claim 1 , wherein the at least one indentation of the at least one of the sidewalls comprises a first indentation and a second indentation spaced from the first indentation, wherein the at least one indentation of the support structure comprises a third indentation contacting and forming an abutment with the first indentation, and a fourth indentation contacting and forming an abutment with the second indentation.

6. A barrier element according to claim 1 , characterised in that both the side walls of the casing are connected to the support structure at least at two spaced apart locations, such that between the at least two spaced apart connection locations of the support structure and each of the side walls the support structure and the side walls are on distance of each other.

7. A barrier element according to claim 1 , characterised in that at least one of the side walls is provided with at least one slit, that cooperates with a protruding part of the casing support structure.

8. A barrier element according to claim 1 , characterised in that the side walls are formed by a concatenation of straight wall parts.

9. A barrier element according to claim 1 , characterised in that the upper wall is connected to the support structure.

10. A barrier element according to claim 1 , characterised in that the support structure comprises a base having a trapezium-shaped cross-section in a plane perpendicular to the longitudinal direction of the casing.

11. A barrier element according to claim 10 , characterised in that the lower part of the side walls abuts the base of the support structure.

12. A barrier element according to claim 1 , characterised in that the at least one support structure comprises an essentially vertical plate positioned perpendicular to the longitudinal side walls of the casing.

13. A barrier element according to claim 12 , characterised in that the essentially vertical plate of the support structure transfers into an essentially horizontal support plate at the bottom end of the support structure.

14. A barrier element according to claim 1 , characterised in that at least one side wall of the casing at a lower end bends inwards and the support structure is near the bottom end provided with a notch for receiving said inwardly bended end of the side wall.

15. A barrier element according to claim 1 , characterised in that the casing support structure is provided with a holder directed towards the top side of the barrier and the upper wall is provided with an aperture in line with the holder such that the holder is accessible from the outside of the barrier element.

16. A barrier element according to claim 1 , characterised in that an end side of the longitudinal casing is provided with a spacer plate, which spacer plate has a contour that follows the inside of the elongated casing.

17. A barrier element for bounding a carriageway, comprising:

an elongated casing, comprising two opposing longitudinal side walls and an upper wall joining the two side walls; and

at least one casing support structure located in the elongate casing and connecting to both the side walls;

wherein at least one of the side walls is provided with at least one indentation, elongated in the direction of elongation of the casing and projecting towards the support structure, and

wherein the support structure is at a side facing one of the side walls provided with at least one indentation projecting away from said side wall to contact and form an abutment with the indentation provided in said side wall.

18. A barrier element according to claim 17 , wherein the at least one indentation of the at least one of the sidewalls comprises a first indentation and a second indentation spaced from the first indentation, wherein the at least one indentation of the support structure comprises a third indentation contacting and forming an abutment with the first indentation, and a fourth indentation contacting and forming an abutment with the second indentation.
