Mounting bracket assemblies and methods
A mounting bracket assembly is provided in which a mounting bracket includes a first attachable bracket piece and a second attachable bracket piece, a first fastener, a second fastener, and a third fastener. Each attachable bracket piece has a top member and a bottom member connected to the top member at an angle. The first clamp is attached to the top member of the first attachable bracket piece by the first fastener. The second clamp is attached to the top member of the second attachable bracket piece by a second fastener. The third fastener secures the bottom member of the first attachable bracket piece to the bottom member of the second attachable bracket piece. The mounting bracket defines a beam insertion aperture between the top members and the bottom members. The mounting bracket assembly may include a first integral grounding device located adjacent the top member of the first attachable bracket piece or adjacent the top member of the second attachable bracket piece. The first integral grounding device is configured to electrically bond a frame of an electricity generating device to the mounting bracket assembly. The mounting bracket assembly may further include a second integral grounding device configured to electrically bond a torque tube to the mounting bracket assembly.

a mounting bracket including a first attachable bracket piece and a second attachable bracket piece, each attachable bracket piece having a top member and a bottom member connected to the top member, the mounting bracket defining a beam insertion aperture between the top members and the bottom members;
a first clamp attached to the top member of the first attachable bracket piece by a first fastener;
a second clamp attached to the top member of the second attachable bracket piece by a second fastener; and
a third fastener securing the bottom member of the first attachable bracket piece to the bottom member of the second attachable bracket piece.
2. The mounting bracket assembly of claim 1 further comprising a first integral grounding device located adjacent the top member of the first attachable bracket piece or adjacent the top member of the second attachable bracket piece, the first integral grounding device being configured to electrically bond a frame of an electricity generating device to the mounting bracket assembly.
3. The mounting bracket assembly of claim 2 wherein the first integral grounding device is a grounding strip attached to an end portion of the top member of the first attachable bracket piece or an end portion of the top member of the second attachable bracket piece.
4. The mounting bracket assembly of claim 3 wherein the first or second fastener includes a clamping nut such that rotating the clamping nut compresses the end portion of the top member of the first attachable bracket piece or second attachable bracket piece, thereby compressing the grounding strip and electrically grounding the electricity generating device.
5. The mounting bracket assembly of claim 2 wherein the mounting bracket is treated to be corrosion-resistant.
6. The mounting bracket assembly of claim 5 wherein the mounting bracket is anodized.
7. The mounting bracket assembly of claim 6 wherein the first integral grounding device is double-sided.
8. The mounting bracket assembly of claim 5 further comprising at least a second integral grounding device located on the mounting bracket.
9. The mounting bracket assembly of claim 8 further comprising a third integral grounding device located on the mounting bracket, the third integral grounding device being configured to electrically bond the mounting bracket assembly to a torsion beam.
10. The mounting bracket assembly of claim 1 wherein the beam insertion aperture has an octagonal shape.
11. A mounting assembly comprising:
at least one support column;
a torsion beam connected to the support column;
a mounting rack attached to the torsion beam;
a mounting bracket assembly mounting the mounting rack to the torsion beam, the mounting bracket assembly including:
a mounting bracket including a first attachable bracket piece and a second attachable bracket piece, each attachable bracket piece having a top member and a bottom member connected to the top member, the mounting bracket defining a beam insertion aperture between the top members and the bottom members, the torsion beam being inserted in the beam insertion aperture;
a first clamp attached to the top member of the first attachable bracket piece by a first fastener;
a second clamp attached to the top member of the second attachable bracket piece by a second fastener; and
a third fastener securing the bottom member of the first attachable bracket piece to the bottom member of the second attachable bracket piece.
12. The mounting assembly of claim 11 further comprising a grounding strip attached to an end portion of the top member of the first attachable bracket piece or an end portion of the top member of the second attachable bracket piece, the grounding strip being configured to electrically bond a frame of an electricity generating device to the mounting bracket assembly.
13. The mounting assembly of claim 12 wherein the first or second fastener includes a clamping nut such that rotating the clamping nut compresses the end portion of the top member of the first attachable bracket piece or second attachable bracket piece, thereby compressing the grounding strip and electrically grounding the electricity generating device.
14. The mounting assembly of claim 12 wherein the electricity generating device is a photovoltaic module.
15. The mounting assembly of claim 11 wherein the torsion beam has an octagonal cross section and the beam insertion aperture has a corresponding octagonal shape.
16. The mounting assembly of claim 11 wherein each of the first and second clamp has an angled mating surface corresponding to an angled end of a respective top member such that each clamp mates with the top member at a defined mating angle.
17. The mounting assembly of claim 16 wherein varying the defined mating angle of the first or second clamp in relation to a respective top member changes a gripping force of the mounting bracket assembly on an electricity generating device.
18. The mounting assembly of claim 16 wherein varying the defined mating angle of the first or second clamp in relation to a respective top member changes a clamping force of the mounting bracket assembly on an electricity generating device.
19. A mounting bracket assembly comprising:
a mounting bracket including at least one top member and a bottom member connected to the top member, the mounting bracket defining a beam insertion aperture between the top member and the bottom member;
at least one clamp attached to the top member, the clamp having an angled mating surface corresponding to an angled end of the top member such that the clamp mates with the top member at a defined mating angle;
a threaded rod securing the clamp to the mounting bracket, the threaded rod running through the at least one clamp and parallel to the at least one top member; and
a clamping nut securing the threaded rod to the clamp and the mounting bracket;
wherein rotating the clamping nut secures the mounting bracket assembly to a torsion beam.
20. The mounting bracket assembly of claim 19 further comprising a grounding strip attached to an end portion of the at least one top member.
