Abstract

The invention relates to a roof tile (1) with a central brim (3) and at least one lateral cover or water beading (2 or 6) and a watercourse (4) located between them, in whose region a water stop (5) is disposed. This water stop (5) is partially pressed with its edges in the region of the watercourse (4), of the central brim (3) and of the lateral beading (2) into the material of the roof tile blank. Such water stop is comprised of a flexurally elastic, thin small plate, and specifically of a material which does not conform to the material of the roof tile (1).

Claims

1. Roof tile (1) with at least one watercourse (4) delimited by elevations (2, 3), in the proximity of which watercourse a water stop (5, 7;

13, 14;

23) is disposed, such that at least some of its margin regions engage into the wall of the watercourse (4) and into the walls of the elevations (2, 3), characterized in that the water stop (5, 7;

13, 14;

23) is comprised of a flexurally elastic small plate.

2. Roof tile as claimed in claim 1, characterized in that the water stop (5, 7;

13, 14;

23) is comprised of a metal or a metal alloy.

3. Roof tile as claimed in claim 1, characterized in that the water stop (5, 7;

13, 14;

23) is comprised of a synthetic material.

4. Roof tile as claimed in claim 1, characterized in that the coefficient of thermal expansion of the water stop (5, 7;

13, 14;

23) approaches the coefficient of thermal expansion of the roof tile (1).

5. Roof tile as claimed in claim 1, characterized in that the water stop (5, 7;

13, 14;

23) has a thickness of less than 3 mm.

6. Roof tile as claimed in claim 1, characterized in that the water stop (5, 7;

13, 14;

23) has a thickness of more than 0.25 mm.

7. Roof tile as claimed in claim 1, characterized in that the water stop (5, 7;

13, 14;

23) has a thickness of approximately 1 mm.

8. Roof tile as claimed in claim 1, characterized in that the water stop (5, 7;

13, 14;

23) is developed in the form of a wedge at its lateral margins.

9. Roof tile as claimed in claim 1, characterized in that the water stop (5, 7;

13, 14;

23) is developed in the form of a trapezoid.

10. Roof tile as claimed in claim 9, characterized in that the short side of the trapezoid and the lateral sides (9, 10) of the trapezoid are pressed into the roof tile (1), while the long side of the trapezoid is substantially exposed.

11. Roof tile as claimed in claim 9, characterized in that the angle between the long side of the trapezoid and the lateral sides (9, 10) is between 40 and 70 degrees.

12. Roof tile as claimed in claim 9, characterized in that the angle between the long side of the trapezoid and the lateral sides is approximately 57 degrees.

13. Roof tile as claimed in claim 1, characterized in that the water stop (5, 7;

13, 14;

23) is developed in the form of a segment of a circle.

14. Roof tile as claimed in claim 1, characterized in that the water stop (5, 7;

13, 14;

23) is developed in the form of a sickle.

15. Roof tile as claimed in claim 1, characterized in that the water stop (5, 7;

13, 14;

23) includes anchoring elements (19-22).

16. Roof tile as claimed in claim 10 and claim 15, characterized in that the anchoring elements (19-22) are provided at the corners of the trapezoid.

17. Roof tile as claimed in claim 10 or claim 16, characterized in that the anchoring elements (19-22) are developed in the form of hooks.

18. Roof tile as claimed in claim 10, characterized in that the long side (24) of the trapezoid is higher at its ends than in the center.

19. Roof tile as claimed in claim 1, characterized in that one of the elevations delimiting the watercourse (4) is a central brim (3).

20. Roof tile as claimed in claim 1, characterized in that further elevations delimiting the watercourse (4) are lateral cover or water beadings (2, 6).

21. Roof tile as claimed in claim 1, characterized in that the water stop (5, 7;

13, 14;

23) is disposed at a distance of at least 10 mm from the ridge-end edge (30) of the roof tile (1).

22. Roof tile as claimed in claim 21, characterized in that the water stop (5, 7;

13, 14;

23) is disposed at a distance of 25 mm from the ridge-end edge (30) of the roof tile (1).

23. Roof tile as claimed in claim 19, characterized in that the central brim (3) includes a drainage channel disposed in front of the water stop (5, 7;

13, 14;

23).

24. Roof tile as claimed in claim 1, characterized in that the water stop (5, 7;

13, 14;

23) penetrates at least 0.5 mm into the roof tile (1).
