Method for using a bracket assembly

1. A method for using a bracket assembly comprising:

providing the bracket assembly comprising a first plate, a second plate rotatable relative to the first plate, a seating frame, and a lever assembly, the lever assembly comprising a rod and a lever, wherein the first plate defines a first end and a second end opposite the first end, the seating frame extends from the second end of the first plate, and the seating frame comprises a first member and a second member;

engaging a beam with the first and second plates; and

actuating the lever to decrease a space between the first and second plates to make the bracket assembly more secured with the beam;

wherein:

engaging the beam with the first and second plates comprises positioning a free end of the first member on a first side of the beam and positioning a free end of the second member on a second side of the beam;

the second member comprises one of a bent section or a curved section extendable over a rim of the beam and configured to support the bracket assembly on the beam; and

a first portion of the one of the bent section or the curved section extends generally upward from the second end of the first plate.

2. The method of claim 1 , wherein actuating the lever comprising rotating a free end of the lever to move the rod towards the second plate and to push the second plate towards the first plate.

3. The method of claim 2 , wherein pushing the second plate towards the first plate comprises rotating the second plate relative to the first plate.

4. The method of claim 3 , wherein:

a plate opening is formed through the first plate between the first end and the second end;

the second plate defines a first plate end extending through the plate opening; and

the second plate is rotatable relative to the first plate at the plate opening.

5. The method of claim 3 , wherein:

the lever is connected to a first rod end of the rod;

the lever further comprises a cam surface engaged with the second plate; and

pushing the second plate towards the first plate comprises pushing the cam surface of the lever against the second plate.

6. The method of claim 5 , wherein the lever is pivotably connected to the first rod end, and wherein rotating the second plate relative to the first plate further comprises rotating the lever between an open position and a closed position.

7. The method of claim 1 , further comprising engaging a bracket bar with the bracket assembly, and wherein the bracket bar extends substantially transverse to the beam.

8. The method of claim 7 , wherein engaging the bracket bar with the bracket assembly comprises engaging the bracket bar with a hanger member, the hanger member extending from the first end of the first plate distal to the beam.

9. The method of claim 8 , wherein:

the hanger member comprises a first wall and a second wall that is parallel to the first wall;

a first hanger opening is formed through the first wall and a second hanger opening is formed through the second wall; and

engaging the bracket bar with the hanger member comprises extending the bracket bar through each of the first and second hanger openings.

10. The method of claim 9 , wherein:

the hanger member further comprises a transverse wall connecting the first wall to the second wall;

a fastener extends through the transverse wall; and

the method further comprises engaging the bracket bar with the fastener to couple the bracket bar to the hanger member.

11. The method of claim 10 , wherein the fastener comprises a bolt and a wingnut.

12. The method of claim 1 , wherein the beam comprises a flange, a web extending perpendicularly from the flange, and the rim, and wherein the second end of the first plate is positioned adjacent to the rim.

13. The method of claim 1 , wherein:

the second member defines a lower section;

the lower section extends substantially downward from the one of the bent section or the curved section; and

the lower section defines the free end of the second member.

14. The method of claim 13 , wherein:

the bent section further comprises a second portion disposed between the first portion and the lower section;

the second portion extends generally downward from the first portion; and

the first portion and the second portion define an inverted notch configured to receive an upper portion of the rim.
