Roof installation support fixing device and roof installation system

1. A fastener for a roof installation support, the fastener comprising:

a baseplate section; and

a U-shaped profile section projecting upward from the baseplate section, the “U” being open toward the baseplate section and configured to surround and positively fix a profile section of the roof installation support without additional fastening means,

wherein an E-modulus of a material of the profile section is greater than an E-modulus of a material of the baseplate section.

2. The fastener according to claim 1 , wherein the baseplate section has a strip-shaped first partial section from which the profile section rises up and a second partial section, which extends from the first partial section up to a longitudinal side as a widened area and is more flexible than the first partial section.

3. The fastener according to claim 1 , which is constructed as integral and/or is manufactured of unified material.

4. The fastener according to claim 3 , which is manufactured from a first material component for the baseplate section and a second material component for the profile section.

5. The fastener according to claim 1 , wherein at least the baseplate section is manufactured from heat weldable material.

6. The fastener according to claim 1 , wherein corner areas of the baseplate section are rounded off by radii.

7. The fastener according to claim 1 , wherein one length of the profile section is at least three times as large as a maximal extent of the profile section in a direction perpendicular to the longitudinal direction and/or wherein the profile section has a constant material thickness.

8. The fastener according to claim 1 , wherein a material thickness of the profile section is greater than a material thickness of the baseplate section.

9. The fastener according to claim 3 , wherein a height of the profile section is greater than a width of the profile section.

10. A roof installation system having at least one roof installation support and fasteners according to claim 1 .

11. The roof installation system according to claim 10 , wherein the roof installation support has a longitudinally extended base body with two longitudinal sides and two end face sides, and the fasteners are configured to attach at least one longitudinal side of the roof installation system.

12. The roof installation system according to claim 10 , comprising two or more fasteners per roof installation support.

13. The roof installation system according to claim 12 , comprising at least one first of said fasteners and one second of said fasteners, separate from the first fastener, wherein the first fastener is provided for attaching a first longitudinal edge of the roof installation support and the second fastener is provided for attaching a second longitudinal edge of the roof installation support.

14. A roof installation system having at least one roof installation support and fasteners according to claim 1 , wherein the openings of the “U” face one another.

15. The fastener according to claim 1 , wherein the profile section projects upward from a rib formed in the baseplate section.

16. The fastener according to claim 1 , wherein the E-modulus of the material of the profile section is at least 1.2 times greater than the E-modulus of the material of the baseplate section.

17. The fastener according to claim 1 , wherein the E-modulus of the material of the profile section is at least 1.5 times greater than the E-modulus of the material of the baseplate section.

18. The fastener according to claim 1 , wherein the E-modulus of the material of the profile section is at least two times greater than the E-modulus of the material of the baseplate section.

19. The fastener according to claim 1 , wherein the material of the baseplate section is manufactured from PVC, TPO, or an adhesive material.
