Magnetic straking such as for utility or communications tower
Magnetic straking can optionally be temporarily attached to a ferromagnetic structure or other structure capable of magnetic attachment thereto, allowing observation or testing of the structure's performance before optional permanent attaching of such straking to the structure, such as by welding or the like.
1. A magnetic straking element for magnetic attachment to a structure to provide fluid-flow adjustment around the structure, mechanical reinforcement to the structure, or both, the straking comprising:
an elongate member, including one or more permanent magnets extending from a first side of the structure for magnetic attachment to the structure;
a fin jutting outward from the elongate member from an opposing second side of the structure to adjust fluid flow around the structure when the straking is attached to the structure; and
weld offsets, protruding from the first side of the structure, the weld offsets protruding to provide a height matching a height of the permanent magnets such that the weld offsets make contact with an underlying portion of the structure when the straking is magnetically attached to the underlying structure using the one or more permanent magnets, such that the weld offsets are configured to provide contact to the structure to permit welding of the straking to the structure.
2. The straking of claim 1 , wherein the elongate member includes length of angle iron or other angle material.
3. The straking of claim 2 , wherein at least one permanent magnet is affixed at one or both ends of the elongate member.
4. The straking of claim 3 , wherein at least one permanent magnet is affixed between ends of the elongate member.
5. The straking of claim 3 , wherein the at least one permanent magnet is bolted to the elongate member.
6. The straking of claim 1 , wherein the fin is arranged to just orthogonally from the underlying structure when the straking is attached thereto.
7. The straking of claim 1 , wherein the elongate member includes length of triangle iron or other triangle material.
8. A method of adjusting fluid flow around a structure capable of magnetic attachment thereto by a permanent magnet, the method comprising:
magnetically attaching one or more straking elements to the structure, the straking comprising: an elongate member, including one or more permanent magnets extending from a first side of the structure for magnetic attachment to the structure; a fin jutting outward from the elongate member from an opposing second side of the structure to adjust fluid flow around the structure when the straking is attached to structure; and weld offsets, protruding from the first side of the structure, the weld offsets protruding to provide a height matching a height of the permanent magnets such that the weld offsets make contact with an underlying portion of the structure when the straking is magnetically attached to the underlying structure using the one or more permanent magnets, such that the weld offsets are configured to provide contact to the structure to permit welding of the straking to the structure; and
then permanently attaching the one or more straking elements to the structure.
9. The method of claim 8 , further comprising
evaluating the structure with one or more straking elements attached thereto to determine whether more or fewer straking elements or a different arrangement of straking elements is desired before permanently attaching the one or more straking elements to the structure.
10. The method of claim 8 , wherein permanently attaching the one or more straking elements to the structure comprises welding.
11. The method of claim 8 , comprising removing or moving at least one magnetically attached straking elements from or with respect to the structure before permanently attaching the one or more straking elements to the structure.
