MULTIPLE WALL CONNECTION OVER PIERS
A solar tracker including at least one pair of piers configured to be secured in the ground and defining a span between the pair, a bearing supported on the pier, and a torque tube supported in the bearing such that the bearing enables rotation of the torque tube, the torque tube including a double wall thickness area, wherein the double wall thickness area limits deflection of the torque tube along the span.
1 . A wall reinforcement comprising:
a pair of doubler plates configured to receive a tube therebetween;
at least one flange extending from each side of each of the doubler plates;
at least one hole formed in each flange;
a U-bolt configured to pass through a hole in each flange; and
a backer plate configured to receive threaded ends of the U-bolt extending through holes in the flange on each side of the doubler plates; wherein
the U-bolt and backer plate are configured to secure the doubler plates to the tube.
2 . The wall reinforcement of claim 1 , wherein the pair of doubler plates stiffen a tube around which they are placed.
3 . The wall reinforcement of claim 2 , wherein the pair of doubler plates are configured to be received in a bearing of a solar tracker.
4 . The wall reinforcement of claim 3 , wherein the pair of doubler plates are placed on a top and a bottom surface of the tube.
5 . The wall reinforcement of claim 3 , wherein the pair of doubler plates are placed at on side surfaces of the tube.
6 . The wall reinforcement of claim 3 , wherein the doubler plates are placed at high load areas of the tube.
