Abstract

A roof panel for sloped roofs includes a self-supporting reinforced plate concrete-like materials, wherein the reinforcement above the plate has bars running along the slope of the roof. In the vicinity of these bars, attaching elements are arranged which bear the roofing material. In order to protect these reinforcement elements from the influence of the weather, they are embedded into concrete ribs, whereby these concrete ribs undertake the function of holding the attaching elements for the roof covering.

Claims

1. A sloped roof, comprising a roof panel having a self-supporting, reinforced plate (1) of age-hardenable material, including a reinforcement for the plate (1) comprising bars (3b) running generally parallel to the roof slope above the plate (1), attachment elements (4) arranged proximate to the bars (3b) for attaching roofing material to the panel, ribs (2) running generally parallel to the roof slope above the plate (1) and joined in one piece with the plate (1), said ribs serving to contain and enclose the bars (3b) on all sides, and wherein the attachment elements (4) are disposed on a side of the ribs (2) facing away from the plate (1).

2. The sloped roof according to claim 1, wherein the age-hardenable material comprises concrete or a concrete-like material.

3. The sloped roof according to claim 2, wherein the ribs (2) are made of concrete or a concrete-like material.

4. The sloped roof according to claim 1, wherein the attachment elements (4) are borne by the ribs (2).

5. The sloped roof according to claim 1, wherein the attachment elements (4) are cemented into the ribs (2) by projecting fasteners (4a).

6. The sloped roof according to claim 5, wherein said fasteners are selected from the group consisting of pins and screw nails.

7. The sloped roof according to claim 5, wherein the attachment elements (4) are additionally held to the ribs (2) by an interlocking connection.

8. The sloped roof according to claim 1, wherein the attachment elements comprise stringers running generally parallel to the roof slope.

9. The sloped roof according to claim 1, wherein the attachment elements (4) are made of a material which is a poor heat conductor.

10. The sloped roof according to claim 9, wherein the poor heat conducting material is selected from the group consisting of wood, plastic and rock wool.

11. The sloped roof according to claim 1, wherein the attachment elements (4) are attached to the ribs (2) through an intervening layer of insulation.

12. The sloped roof according to claim 1, further comprising insulation material (6) arranged on the plate (1) between the ribs (2), the insulation material (6) extending to a height at least to the side of the ribs (2) facing away from the plate (1).

13. The sloped roof according to claim 12, wherein the height of the insulation material extends to about a level of the attachment elements (4).

14. The sloped roof according to claim 1, wherein the attachment elements (4) include upper sides which are covered by an underlayer (7) which extends over almost the entire roof panel.

15. The sloped roof according to claim 1, wherein the reinforcement comprises prestressed reinforcing bars (3a, 3b).
