Abstract

A roof framing structure (20) is disclosed, and includes a plurality of primary supports (30) (e.g., rafters) that may be disposed in parallel relation and extend along the roof pitch (14). One or more secondary supports (40) extend between each adjacent pair of primary supports (30). Each secondary support (40) is of a triangular cross-sectional configuration, and may extend orthogonally to the various primary supports (30).

Claims

1. A roofing section, comprising:

a panel system comprising a plurality of panels; and

a roof framing structure comprising a plurality of structural supports each having a length dimension and disposed in parallel relation;

wherein each of said plurality of structural supports comprises a closed, three-sided perimeter with at least one side comprising a flat section and with a hollow interior, wherein a maximum wall thickness of each of said plurality of structural supports is ⅜

″

, wherein said panel system is disposed in overlying relation to said roof framing structure, wherein said flat section of each of said plurality of structural supports is in a relative position to said panel system that is selected from the group consisting of engaging a corresponding flat portion of an underside of said panel system or disposed in closely-spaced relation to said corresponding flat portion of said underside of said panel system, and wherein no portion of said roof framing structure is closer to said underside of said panel system than said flat section of said plurality of structural supports; and

wherein said roof framing structure comprises a plurality of primary supports disposed in parallel relation to each other and a plurality of secondary supports disposed in parallel relation to each other in a different orientation than said plurality of primary supports, wherein an elevation of each of said plurality of primary supports continually changes proceeding along their respective length dimension, wherein an elevation of each of said plurality of secondary supports remains constant proceeding along their respective length dimension, wherein said plurality of structural supports is selected from the group consisting of said plurality of primary supports, said plurality of secondary supports, or both, and wherein a flat, uppermost surface of each of said plurality of primary supports and a flat, uppermost surface of each of said plurality of secondary supports are coplanar.

2. The roofing section of claim 1, wherein each of said plurality of structural supports is of a triangular cross-section taken perpendicularly to a corresponding said length dimension and defines said three-sided perimeter.

3. The roofing section of claim 2, wherein said triangular cross-section comprises an equilateral triangle.

4. The roofing section of claim 1, wherein each said secondary support is directly attached to two said primary supports.

5. The roofing section of claim 1, further comprising a plurality of brackets, wherein each said bracket provides an interconnection between one said primary support and one said secondary support.

6. The roofing section of claim 5, wherein each said bracket comprises a V-shaped receptacle.

7. The roofing section of claim 5, wherein each said bracket is mounted to a corresponding said primary support.

8. The roofing section of claim 5, wherein each said bracket supports an end portion of a corresponding said secondary support.

9. The roofing section of claim 1, wherein each said panel is a metal panel.

10. The roofing section of claim 1, wherein each said panel is a standing seam panel.

11. A roofing section, comprising:

a roof framing structure comprising a plurality of structural supports each having a length dimension, wherein said plurality of structural supports comprises;

a plurality of primary supports, wherein each said primary support has a length dimension that extends in a direction of a roof pitch;

a plurality of secondary supports each having a hollow interior and a maximum wall thickness of ⅜

″

, wherein each said secondary support extends between at least two of said primary supports in a direction that corresponds with a length dimension of said plurality of secondary supports, wherein each of said plurality of secondary supports comprises a closed perimeter having only first, second, and third sides, wherein said first side of each said secondary support is flat and defines an uppermost surface of said secondary support, and wherein said first, second, and third sides of said secondary support collectively define a triangular cross-sectional configuration that is taken perpendicularly to said length dimension of said secondary support; and

a plurality of brackets, wherein each said bracket provides an interconnection between one said primary support and one said secondary support; and

a panel system disposed in overlying relation to said roof framing structure, wherein said panel system comprises a plurality of panels, wherein said first side of each said secondary support is in a relative position to said panel system that is selected from the group consisting of engaging a corresponding flat portion of an underside of said panel system or disposed in closely-spaced relation to said corresponding flat portion of said underside of said panel system, and wherein no portion of said roof framing structure is closer to said underside of said panel system than said first side of said plurality of secondary supports.

12. The roofing section of claim 11, wherein each said bracket comprises a V-shaped receptacle for receiving a single said secondary support.

13. The roofing section of claim 11, wherein each said bracket is mounted to a corresponding said primary support.

14. The roofing section of claim 11, wherein each said bracket supports an end portion of a corresponding said secondary support.

15. The roofing section of claim 11, wherein an elevation of each said primary support continually changes proceeding along its corresponding said length dimension, and wherein an elevation of each said secondary support remains constant proceeding along its corresponding said length dimension.
