Load transfer arrangement
An arrangement for making a field repair on a multi-part pole having upper and lower walls joined together by a flanged connection, wherein the welds on the flanged connection are beginning to show signs of failure. The arrangement includes a bracket having a substantially “U”-shaped central portion which spans the flanged connection, and upper and lower elongated portions extending from the central portion, lying flush against and secured to the upper and lower walls of the pole, respectively.
1. An arrangement for transferring forces across a flanged connection of a multi-piece pole having an upper wall above the flanged connection and a lower wall below the flanged connection, comprising:
a plurality of one-piece brackets, each having a rear face and a front face and including upper and lower elongated portions and a U-shaped portion between said upper and lower elongated portions, the rear face of said U-shaped portion being adapted to span over the flanged connection when the rear faces of the upper and lower elongated portions are lying flush against the upper and lower walls of the multi-piece pole;
wherein each of said upper and lower elongated bracket portions defines a plurality of through-openings for receiving fasteners to secure said upper and lower elongated bracket portions to the respective upper and lower walls; and
wherein said front face includes left and right gussets extending along said upper and lower elongated bracket portions.
2. An arrangement for transferring forces across a flanged connection of a multi-piece pole as recited in claim 1 , wherein said left and right gussets also extend along said U-shaped portion.
3. An arrangement for transferring forces across a flanged connection of a multi-piece pole as recited in claim 2 , and further comprising a plurality of blind fasteners for extending through said through-openings to secure said plurality of one-piece brackets to the upper and lower walls.
4. An arrangement for transferring forces across a flanged connection of a multi-piece pole as recited in claim 3 , wherein said rear faces of said upper and lower elongated portions are flat.
5. An arrangement for transferring forces across a flanged connection of a multi-piece pole as recited in claim 1 , and further comprising a multi-piece pole having upper and lower walls and a flanged connection connecting said upper and lower walls together, wherein said one-piece brackets are secured onto said upper and lower walls, with the rear faces of said upper and lower elongated portions lying flush against said upper and lower walls, respectively, with the U-shaped portions spanning said flanged connection, and with a plurality of blind fasteners extending through said through-openings and through the respective wall of said pole to secure said upper elongated portion to said upper wall and said lower elongated portion to said lower wall.
6. An arrangement for transferring forces across a flanged connection of a multi-piece pole as recited in claim 5 , wherein said multi-piece pole is multi-sided, and each of said one-piece brackets is secured along one of the sides of said multi-sided, multi-piece pole, with said rear faces of each of said upper and lower elongated portions of each of said one-piece brackets lying flat against the respective side of said multi-piece, multi-sided pole.
7. An arrangement for transferring forces across a flanged connection of a multi-piece pole as recited in claim 6 , wherein one of said one-piece brackets is secured along each of the sides of said multi-sided, multi-piece pole.
8. An arrangement for transferring forces across a flanged connection of a multi-piece pole as recited in claim 7 , wherein said left and right reinforcing gussets of said one-piece brackets also extend along the front face of said U-shaped portions.
