BACKGROUND
There are over one hundred million utility poles in the U.S. These utility poles are an integral piece of the infrastructure of the country as they provide support for electric wires, cable, and communications wires. However, many of these poles are decades old and have degraded over time, requiring varying degrees of maintenance and repair. For example, steel utility poles may become damaged due to corrosion and may develop holes or other weaknesses that can undermine the structural integrity of the pole. Other types of poles, such as, for example, mono-pole cell-towers and light poles, can experience similar degradation. It is both a time-consuming and expensive process to replace a damaged utility pole, and as such, it is generally desirable to repair a damaged utility pole if possible.
However, patching a hole in a steel utility pole is also a time-consuming process as it typically requires a customized solution, as the size, shape, taper, location, and nature of the corroded portion of a pole will vary from case to case. Additionally, utility poles come in many shapes and sizes. For example, utility poles can be circular, 4-sided, 6-sided, 8-sided, 12-sided, 16-sided, or other suitable configuration. Another complicating factor is that the pole manufacturing process is not always perfect, and so it may be necessary to measure the individual pole before developing a repair solution. Thus, in order to develop a customized pole repair solution, an engineering team may be required to first spend considerable time studying and understanding the geometry of the pole and the geometry of the damaged area. Thus, there is a need for a standardized system and method of repairing a steel utility pole.
SUMMARY
Some or all of the above deficiencies may be addressed by certain embodiments of the disclosed technology. One or more utility pole repair plates may be used to repair, strengthen, harden, or uprate a utility pole without the need for engineering a customized solution for that particular pole. Utility pole repair plates may have a variety of standardized designs, which each standardized design corresponding to a particular utility pole geometry. For example, utility pole repair plates may be designed for use on multi-sided poles including, but not limited to, an 8-sided utility pole, a 12-sided utility pole, or a 16-sided utility pole. Thus, a repair technician may be enabled to quickly respond to a call to repair a utility pole on any geometry by carrying a supply of utility pole repair plates corresponding to each utility pole geometry. Due to the interconnecting design of the utility pole repair plates, the utility pole repair plates may be used to repair, strengthen, harden, or uprate a portion of a utility pole or the entire circumference by selecting the number of utility pole repair plates necessary for the situation.
According to an example embodiment, a pole repair plate is provided. The pole repair plate may have a top edge, a bottom edge, a first side edge and a second side edge.

According to some embodiments, the first substantially planar plate segment may be positioned flush against a first side of the pole, and the second substantially planar plate segment may be positioned flush against a second side of the pole, wherein the second side of the pole is adjacent to the first side of the pole. The method may further include placing a second repair plate substantially flush against the pole, wherein the second repair plate is placed adjacent to the first repair plate, such that: a first substantially planar plate segment of the second repair plate may be positioned flush against the second side of the pole, a second substantially planar plate segment of the second repair plate may be positioned flush against a third side of the pole, wherein the third side of the pole may be adjacent to the second side of the pole, and the end of the first substantially planar plate segment of the second repair plate may be received by the gap formed between the fourth substantially planar plate segment of the first repair plate and the surface of the second side of the pole. The method may further include affixing the first substantially planar plate segment of the second repair plate to the fourth substantially planar plate segment of the first repair plate. The method may further include affixing the first and second substantially planar plate segments of the first repair plate to the first and second sides of the pole, respectively.

DETAILED DESCRIPTION
Embodiments of the disclosed technology include utility pole repair plate apparatuses and methods that can be used to repair a utility pole and, in particular, a steel or metal utility pole. Further, although this disclosure is generally directed towards describing the repair or strengthening of utility poles, it should be understood that the utility pole repair plates described herein may be used to repair a wide variety of other types of poles, including, for example, mono-pole cell-towers and light poles. One or more utility pole repair plates of the current disclosure may be deployed to quickly repair, strengthen, harden, or uprate a utility pole without the need for engineering a customized solution for that particular pole. By providing a standardized, inter-connecting design, the utility pole repair plates of the current disclosure may fit a multitude of different repair locations on both tapered and non-tapered utility poles and accommodate variations across poles. According to some embodiments, the utility pole repair plates can be used to repair, strengthen, harden, or uprate the entire circumference of the utility pole. In some embodiments, the utility pole repair plates may be used to repair, strengthen, harden, or uprate a partial circumference of a utility pole.
According to certain embodiments a utility pole repair plate may include two substantially planer plate segments connected together that may be designed to be attached to two adjacent sides of a utility pole. In some embodiments, a utility pole repair plate may further include two more substantially planar plate segments designed to attach to an adjacent repair place. The angles formed between the various plate segments in the utility pole repair plate may be designed to fit a particular shape of pole, for example, a 4-sided, 6-sided, 8-sided pole, 12-sided pole, or a 16-sided pole. One advantage of the utility pole repair plate is that for a given pole design (e.g., an 8-sided pole), the utility pole repair plate may be used to fit on a wide variety of different repair locations on the pole, which may include tapered regions of the pole, thus creating a “one size fits all” type of repair solution for a pole with a given number of sides. For poles that do not have a regular shape (i.e., not all sides and angles are equal), different repair plates may be used in combination to repair the pole.
Throughout this disclosure, certain embodiments are described in exemplary fashion in relation to a utility pole repair plate designed to repair a damaged 8-sided utility pole. However, embodiments of the disclosed technology are not so limited. In some embodiments, the disclosed apparatuses and methods may be effective in repairing poles of different geometries (e.g., a 4, 6, 12, or 16-sided utility pole) or for strengthening undamaged utility poles. Furthermore, the figures provide examples of standard configurations of utility poles, but it will be appreciated by those of skill in the art that the utility pole repair plates disclosed herein may be modified or adapted for use with other multi-faceted poles, regardless of the quantity of facets that comprise the respective cross-section. Furthermore, variations in pole designs, such as for example, faceted oval shaped poles, may also be accommodated by variations to the utility pole repair plates disclosed herein.
Some embodiments of the disclosed technology will be described more fully hereinafter with reference to the accompanying drawings. This disclosed technology may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth therein.
In the following description, numerous specific details are set forth. However, it is to be understood that embodiments of the disclosed technology may be practiced without these specific details. In other instances, well-known methods, structures, and techniques have not been shown in detail in order not to obscure an understanding of this description. References to “one embodiment,” “an embodiment,” “example embodiment,” “some embodiments,” “certain embodiments,” “various embodiments,” etc., indicate that the embodiment(s) of the disclosed technology so described may include a particular feature, structure, or characteristic, but not every embodiment necessarily includes the particular feature, structure, or characteristic. Further, repeated use of the phrase “in one embodiment” does not necessarily refer to the same embodiment, although it may.
Throughout the specification and the claims, the following terms take at least the meanings explicitly associated herein, unless the context clearly dictates otherwise. The term “or” is intended to mean an inclusive “or.” Further, the terms “a,” “an,” and “the” are intended to mean one or more unless specified otherwise or clear from the context to be directed to a singular form.
Unless otherwise specified, the use of the ordinal adjectives “first,” “second,” “third,” etc., to describe a common object, merely indicate that different instances of like objects are being referred to, and are not intended to imply that the objects so described must be in a given sequence, either temporally, spatially, in ranking, or in any other manner.
Various systems and methods are disclosed for repairing, strengthening, hardening, or uprating a utility pole, and will now be described with reference to the accompanying figures.
As described herein, embodiments of the disclosed technology include utility pole repair plates for strengthening, uprating, hardening, or repairing a damaged or weakened utility pole and methods of using the same. Utility poles are commonly manufactured to have a polygonal cross-sectional shape. For example, FIG. 1 shows a cross-sectional view of an 8-sided utility pole 100 according to some embodiments. According to the embodiment shown in FIG. 1, the utility pole 100 has eight sides and forms an approximately regular octagon such that each side of the utility pole 100 is approximately the same length and all of the angle formed between each pair of two adjacent sides is approximately equal. As will be understood by those of skill the in the art, each internal angle between two adjacent sides of utility pole 100 is approximately 135 degrees. Although much of the disclosure refers to poles having a generally regular polygonal shape, it will be appreciated by those having skill in the art that combinations of repair plates of the present disclosure may also be utilized to service poles that do not have a regular polygonal cross section, such as, for example, faceted oval-shaped poles.
FIG. 2A shows an embodiment of a utility pole repair plate 202 designed for use with an 8-sided utility pole 100. According to some embodiments, a utility pole repair plate 202 may be made of a single piece of formed metal, having a top edge, two side edges, and a bottom edge. According to some embodiments, a utility pole repair plate 202 may be made of steel, copper, aluminum, stainless steel, fiber reinforced polymer (FRP), or any other suitable metal, alloy, or composite.
According to some embodiments, a utility pole repair plate 202 may include a first substantially planar plate segment 204 attached to a second substantially planar plate segment 206, such that the second plate segment 206 is positioned relative to the first plate segment 204 at an angle. According to some embodiments, the second plate segment 206 may be positioned relative to the first plate segment 204 at an angle designed to approximately match the angle between two adjacent outer surfaces of a utility pole. Thus, for an 8-sided utility pole 100, this angle may be approximately 135 degrees. Throughout this disclosure, references to an approximation of an angle are intended to include angles within 5 degrees of the stated angle. For example, “approximately a 135 degree angle” may refer to any angle in the range of 130 to 140 degrees. In some embodiments, a first substantially planar plate segment 204 may be attached to a second substantially planar plate segment 206 at a shoulder 205. As shown in FIG. 2A, in some embodiments a shoulder 205 can be a rounded surface formed between the first plate segment 204 and the second plate segment 206. According to some embodiments, a rounded shoulder may have an inside bend radius that is the same as the outside bend radius of the utility pole. According to some embodiments, the inside bend radius of the utility pole 100 may be assumed to be 4 times the thickness of the pole, unless otherwise known. In some embodiments, a shoulder 205 may be a non-rounded edge formed between the first plate segment 204 and second plate segment 206. In some embodiments, the shoulder 205 may bulge outwards so that it may have room to accommodate extra material present on a vertex of the exterior surface of a utility pole. According to some embodiments, the shoulder 205 can be affixed to a utility pole by, for example, welding.
In some embodiments, a third substantially planar plate segment 207 may be connected to the second substantially planar plate segment 206. The third plate segment 207 may extend away from the second planar plate segment at a non-zero angle. According to some embodiments, the length of the third substantially planar plate segment 207 and the angle from which it extends away from the second planar plate may be intended to create an offset distance of a particular value, wherein the offset distance is a distance to the far end of the third plate segment 207, measured perpendicularly from the outside face of the second plate segment 206. According to some embodiments, the offset distance may be substantially equal to the thickness or width of a first planar plate segment 204 of an adjacent utility pole repair plate 202, such that the first plate segment 204 may be snuggly positioned between the face of a utility pole 100 and a fourth substantially planar plate segment 208 extending from the third plate segment 207 disposed in a substantially parallel direction to the second plate segment 206. According to some embodiments, the third plate segment 207 may extend away from the second plate segment 206 at, for example, but not limited to, a 45 degree angle, a 154 degree angle, or a 26 degree angle. It will be understood by those of skill in the art that according to various embodiments, the third plate segment 207 may extend away from the second plate segment 206 at any number of different angles and that the angles that have been provided herein are merely non-limiting examples.
In some embodiments, a fourth substantially planar plate segment 208 may be connected to the third substantially planar plate segment 207. As shown in FIG. 2A, according to some embodiments, the fourth plate segment 208 may extend away from the third plate segment 207 such that is disposed in a position that is substantially parallel to the direction of the second plate segment 206. Accordingly, in some embodiments, the fourth plate segment 208 may run parallel to the second plate segment 206, offset by an offset distance that is a function of the length of the third plate segment 207 as well as the angle between the third plate segment 207 and the second plate segment 206. According to some embodiments, the offset distance between the second plate segment 206 and fourth plate segment 208 may be approximately equal to the width or thickness of the first substantially planer plate segment 204.
FIG. 2B shows an embodiment of a utility pole repair plate 212 having a hinge 220 disposed between a first substantially planar plate segment 214 and a second substantially planar plate segment 216. In some embodiments, a hinge 220 may include attachment members 224, 226 that can attach hinge 220 to the first and second plate segments 214, 216. For example, the attachment members 224, 226 can be substantially planar members that attach to the back surface of the first and second plate segments 214, 216, respectfully. According to some embodiments, the attachment members 224, 226 can be welded to the first and second plate segments 214, 216, respectfully. In some embodiments, attachment members 224, 226 may be omitted and the first and second plate segments 214, 216 may attach directly to the hinge 220. The first plate segment 214 may be disposed at a hinge angle 215 relative to the second plate segment 216. In some embodiments, the hinge 220 can enable the first plate segment 214 to rotate relative to the second plate segment 216, thereby allowing for the hinge angle 215 to be adjustable. Similar to the embodiment shown in FIG. 2A, a hinged utility pole repair plate 212 may also include a third substantially planar plate segment 217 attached to the second plate segment 216 and a fourth substantially planar plate segment 218 extending away from the third plate segment 217. The fourth substantially planar plate segment 218 of a hinged repair plate 212 may be disposed substantially parallel to the second plate segment 216 and be offset by an offset distance. According to some embodiments, the offset distance may be substantially equal to the width or thickness of the first plate segment 214.
According to some embodiments, the substantially planar plate segments 204, 206, 207, 208 of a utility pole repair plate 202 described above may each be a generally flat piece of metal. FIGS. 3A and 3B show a side view and perspective view of an embodiment of a utility pole repair plate 202 having a first substantially planar plate segment 204, a second substantially planar plate segment 206, a third substantially planar plate segment 207, and a fourth substantially planar plate segment 208. In some embodiments, each plate segment 204, 206, 207, 208 can be made of steel, copper, aluminum, stainless steel, fiber reinforced polymer (FRP), or any other suitable metal or alloy. According to some embodiments, all of the plate segments 204, 206, 207, 208 may be made of the same material. In some embodiments, one or more of the plate segments 204, 206, 207, 208 may be made of different materials. In some embodiments, a utility pole repair plate 202 may have a thickness that is greater than a wall of the utility pole 100. For example, according to some embodiments, a utility pole repair plate 202 may have a minimum thickness that is 1/16 inch thicker than the utility pole wall. In some embodiments, a utility pole repair plate 202 may have a thickness that is less than or approximately the same as the utility pole wall thickness. For example, in some embodiments, if the utility pole has a wall thickness of less than ¼ inch, then a utility pole repair plate 202 may have the same thickness as the utility pole wall.
According to some embodiments, the utility pole repair plate 202 may be configured to be affixed to two faces of a utility pole 100. Furthermore, in some embodiments, a fourth substantially planar plate segment 208 of a first utility pole repair plate 202 may attach to the first substantially planar plate segment 204 of a second utility pole repair plate 202. FIG. 4 shows a plurality of utility pole repair plates 202 affixed to a utility pole 100. As shown in FIG. 4, for a particular utility pole repair plate 202, the first substantially planar plate segment 204 may be affixed to a first face of the utility pole 100, and the second substantially planar plate segment 206 may be affixed to a second, adjacent face of the utility pole 100. Furthermore, in some embodiments, the shoulder 205 of the utility pole repair plate may generally straddle the intersection of the first and second faces of the utility pole 100, such that the surface of the first and second plate segments 204, 206 may be positioned substantially flush against the surface of the utility pole 100. As shown in FIG. 4, according to some embodiments, a first substantially planar plate segment 204 of a second utility pole repair plate 202 may be positioned between a face of the utility pole 100 and a surface of the fourth substantially planar plate segment 208 of a first repair plate 202. In this way, each utility pole repair plate 202 may be capable of receiving an end of an adjacent plate. Thus, as shown in FIG. 4, in some embodiments, when secured to the utility pole 100, utility pole repair plates 202 can be placed around the entire circumference of the utility pole 100. In some embodiments, one or more utility pole repair plates 202 may be attached to a utility pole 100 to cover a portion of the utility pole 100 that is less than the entire circumference of the utility pole 100. According to some embodiments, the first and second plate segments 204, 206 of a utility pole repair plate 202 may be affixed to the surface of a utility pole 100 by welding the plate segments 204, 206 to the surface of the utility pole 100. According to some embodiments, welding can be performed in the flat position, such that the joint is laid flat. In some embodiments, welds may be fillet welds. According to some embodiments, a top and/or bottom portion or edge of a utility pole repair plate 202 can be “scalloped” into a half-circle (e.g., the edge of the plate may have a series of rounded peaks that may resemble a rectified sinusoidal waveform) or similar, or “castellated,” along the flats and/or bends to create a shape somewhat similar to a castellated nut (e.g., the edge of the plate may have a series of squared peaks that may resemble a square waveform), which may enable the weld to develop additional strength and provide additional fatigue resistance. By scalloping or castellating the plates, the weld length can be increased which may allow a stronger connection to the pole to be achieved with a single side fillet weld. In some embodiments, a first utility pole repair plate 202 may be affixed to a second utility pole repair plate 202 by welding a surface of the fourth plate segment 208 of the first repair plate 202 to a surface of the first plate segment 204 of the second repair plate 202. In some embodiments, a repair plate may be affixed to the utility pole 100 or another repair plate 202 by using bolts, pins, screws, epoxy, adhesive, blind bolts, or any other such attachment means. For example, in some embodiments, the first plate segment 204 may include attachment members, such as bolts or screws, which may extend substantially perpendicularly away from the surface of the first plate segment 204, which can be received by holes in the fourth plate segment 208 of another repair plate 202. According some embodiments, the first plate segment 204 of a first utility pole repair plate 202 and a fourth plate segment 208 of a second utility pole repair plate 202 can each have holes that align with one another when the utility pole repair plates 202 are applied to a utility pole, and the first and second utility pole repair plants may be secured to the pole by an attachment member, such as a screw or bolt, extending through the holes and into the surface of the utility pole. According to some embodiments, if a repair plate 202 is used to repair a section of a utility pole 100 at a base plate or at a bolted flange connection such that it may be welded to the base plate or bolted flange connection, the top end of the repair plate 202 which will not be attached to the base plate or flange can be “scalloped” or “castellated” as described above. In some embodiments, the opposite end of the repair plate 202 which may attach to the base plate or flange may have a lap joint terminate at a distance, for example, 4 inches, above that connection. Accordingly, in some embodiments, the bottom portion of the repair plate 202 may have an extra flat steel projecting horizontally from the vertical edge of the repair plate 202 to allow field trimming and proper fitting for a complete joint penetration (CJP) weld to be performed on the bottom portion of the repair plate 202. According to some embodiments, such a design may simplify the fit-up for the additional CJP weld that may attach the bottom of the repair plate 202 to the base plate or flange.
As described above, utility pole repair plates 202 may be attached to a utility pole 100 through welding or bolting. In some embodiments, a welded repair may involve positioning one or more utility pole repair plates 202 over the area to be reinforced and temporarily attaching it to the utility pole. According to some embodiments, repair plate lap joints may be tack welded to lock in the profile (i.e., the shape of the existing pole), thereby creating a utility pole repair plate assembly that includes a plurality of utility pole repair plates 202 that have been attached to one another. In some embodiments, the repair plate assembly may be removed from the surface of the utility pole and the lap joints on the interior of the repair plate assembly may be stitch welded. In some embodiments, the exterior of the lap joints of the repair plate assembly may be fully welded. As such, in some embodiments, a utility pole repair plate assembly may be created by attaching a plurality of utility pole repair plates 202 to one another in advance of securing the repair plate assembly to the utility pole. According to some embodiments, the interior of the repair plates 202 or utility pole repair plate assembly and the exterior of the utility pole 100 face may be coated with a specified coating system. A coating system can be used to protect the repair plates 202 from corrosion and may also be used to improve the aesthetics of the repair plates 202. Examples of specified coating systems that can be used include, but are not limited to, a cold galvanizing compound, thermal spray, wax coating systems, or various single or multi-coat systems such as zinc-rich primer, epoxy primer/midcoat, and polyurethane or siloxane topcoat. In some embodiments, after being removed and welded together, the utility pole repair plate assembly may be positioned back on the utility pole 100 and the repair plate assembly may be fully welded to the utility pole 100. In some embodiments, the entire repair may be coated with a specified coating system, including the interior of the pole, when applicable. According to some embodiments, if this method is used to repair the entire circumference of the utility pole 100, the above steps may be performed on each half of the utility pole 100, thereby creating two repair plate assemblies. For example, a first repair plate assembly may be configured to cover a first half of the utility pole and a second repair plate assembly may be configured to cover the second half of the utility pole, such that the two halves may be joined and attached together to cover the entire circumference of the utility pole. According to some embodiments, there may be two longitudinal joints joining both halves of two repair plate assemblies and the longitudinal joints may correlate with the neutral axis of the pole.
According to some embodiments, the utility pole repair plates 202 may be utilized to perform a bolted repair of the utility pole 100. In some embodiments a repair plate 202 may be positioned over the pole area to be reinforced and the utility pole 100 may be marked for drilling, or match-drilled, using a positioning hole of the repair plate 202. The repair plate 202 may be removed and a positioning hole may be drilled into the pole. According to some embodiments, the inside face of the repair plate 202 may be coated with a specified coating system and sealed with a specified sealant to prevent moisture from penetrating the repaired area. The repair plate 202 may be repositioned and secured to the utility pole by using, for example, epoxy or a blind bolt. According to some embodiments, additional holes may be drilled in the repair plate 202, continuing through the pole wall, and additional bolts may be installed. According to some embodiments, this process may be repeated until the required number of repair plates have been attached to the utility pole 100. In some embodiments, after the repair plates 202 are attached to the utility pole 100, each lap splice may be drilled through both laps and the pole wall and blind bolts may be installed. According to some embodiments, some or all of the repair plates 202 and interior of the utility pole may be coated with a specified coating system to complete the repair.
According to some embodiments, a damaged or weakened portion of an 8-sided utility pole 100 may be repaired by affixing one or more utility pole repair plates 202 around the pole in at least one or more of the manners described above, such that the surface of the one or more utility pole repair plates covers the damaged or weakened portion of the utility pole 100. According to some embodiments, a hinged utility pole repair plate 212 may be affixed to a utility pole 100 in a manner similar to those of the utility pole repair plate 202 described above, however, the existence of the hinge 220 may enable a user to more easily position the repair plate 212 on the utility pole 100 and relative to adjacent or interconnected repair plates 212. Further, the existence of the hinge 220 may also allow the utility pole repair plate 212 to be accommodate a wider variation of pole shapes and sizes. For example, according to some embodiments, the hinged repair plate 212 may fit on most or all of the different polygonal pole shapes, since the hinge allows all of the different angles to be matched. According to some embodiments, one or more hinged utility pole repair plates 212 may be used in combination with utility pole repair plates 202 to repair an 8-sided utility pole 100.
As previously discussed, utility poles are manufactured in a variety of geometries. According to various embodiments, the angle formed between the first plate segment and a second plate segment of a repair plate may correspond to the angle formed between two adjacent sides of a pole. In some embodiments, the angle formed between the first plate segment and a second plate segment may be approximately equal to the 360° divided by the number of sides of the pole. FIG. 5 illustrates a top cross-sectional view of a 12-sided utility pole 400. As will be understood by those of skill in the art, a regular 12-sided utility pole has 12 sides of approximately equal length, and internal angles of 150 degrees formed between each pair of adjacent sides. FIG. 6A illustrates a utility pole repair plate 502 configured to repair a 12-sided utility pole 400. According to some embodiments, a repair plate 502 may include a first substantially planar plate segment 504, a shoulder 505, a second substantially planar plate segment 506, a third substantially planar plate segment 507, and a fourth substantially planar plate segment 508. According to some embodiments, the angle formed between the first plate segment 504 and second plate segment 506 may be designed to approximately match the angle between two adjacent outer surfaces of a utility pole. Thus, for a 12-sided utility pole 400, this angle may be approximately 150 degrees. Similarly, FIG. 6B shows a hinged utility pole repair plate 512 having a first substantially planar plate segment 514, a second substantially planar plate segment 516, a third substantially planar plate segment 517, a fourth substantially similar planar plate segment 518, and a hinge 520 having attachment members 524, 526. In some embodiments of a hinged utility pole repair plate 512, attachment members 524, 526 may be omitted and the first and second plate segments 514, 516 may attach directly to the hinge 520. As will be appreciated by those of skill in the art, a utility pole repair plate 502 and hinged utility pole repair plate 512 may be used to repair a 12-sided utility pole 400 in the same manner that the utility pole repair plate 202 and hinged utility pole repair plate 212 may be used to repair an 8-sided utility pole 100 as described above. FIG. 7 illustrates a plurality of utility pole repair plates 502 affixed to a 12-sided utility pole 400.
FIG. 8 illustrates a top cross-sectional view of a 16-sided utility pole 700. As will be understood by those of skill in the art, a regular 16-sided utility pole has 16 sides of approximately equal length, and internal angles of 157.5 degrees formed between each pair of adjacent sides. FIG. 9A illustrates a utility pole repair plate 802 configured to repair a 16-sided utility pole 700. According to some embodiments, a repair plate 502 may include a first substantially planar plate segment 804, a shoulder 805, a second substantially planar plate segment 806, a third substantially planar plate segment 807, and a fourth substantially planar plate segment 808. According to some embodiments, the angle formed between the first plate segment 804 and second plate segment 806 may be designed to approximately match the angle between two adjacent outer surfaces of a utility pole. Thus for a 16-sided utility pole, this angle may be approximately 157.5 degrees. Similarly, FIG. 9B shows a hinged utility pole repair plate 812 having a first substantially planar plate segment 814, a second substantially planar plate segment 816, a third substantially planar plate segment 817, a fourth substantially similar planar plate segment 818, and a hinge 820 having attachment members 824, 826. In some embodiments of a hinged utility pole repair plate 812, attachment members 824, 826 may be omitted and the first and second plate segments 814, 816 may attach directly to the hinge 820. As will be appreciated by those of skill in the art, a utility pole repair plate 802 and hinged utility pole repair plate 812 may be used to repair a 12-sided utility pole 700 in the same manner that the utility pole repair plate 202 and hinged utility pole repair plate 212 may be used to repair an 8-sided utility pole 100 as described above. FIG. 10 illustrates a plurality of utility pole repair plates 502 affixed to a 12-sided utility pole 400.
While some utility poles maintain a substantially constant diameter from the base of the utility pole to the top of the utility pole, others are designed to taper from the top to the bottom, such that the diameter of the utility pole becomes smaller towards the top. Accordingly, some embodiments of a utility pole repair plate can include a tapered design, such that the widths of each substantially planar plate segment become smaller on the top edge of the repair plate. FIGS. 11A-11C show various views of a tapered utility pole 1100 having a tapered utility pole repair plate 1102 affixed to it. Tapered utility pole 1100 is depicted to show an exaggerated taper for the purposes of illustration. As shown in these figures, according to some embodiments, the overall width of a tapered utility pole repair plate 1102 is smaller at the top edge of the repair plate 1102 than the bottom edge of the repair plate 1102. In some embodiments, the widths of each plate segment that makes up the repair plate 1102 shrinks towards the top edge of the repair plate 1102. FIGS. 12A-B show a plurality of tapered utility pole repair plates 1102 affixed to the tapered utility pole 1100. Any of the aforementioned embodiments of the utility pole repair plates described herein may also incorporate the tapering aspect shown in these figures. According to some embodiments, a tapered utility pole repair plate may not be required to repair a tapered pole because one or more lap joints of one or more non-tapered utility pole repair plates of the present disclosure may accommodate utility pole taper or other imperfections. According to some embodiments, a lap joint can be formed by the overlapping portions of two adjacent utility pole repair plates. For example, in FIG. 4, a lap joint, typically referred to as a “joggle lap joint” may be formed between the joining of the fourth substantially planar plate segment 208 of a first utility pole repair plate 202 and the first plate segment 204 of a second utility pole repair plate 202.
FIG. 13 is a flow diagram of a method 1300, according to an example implementation. As shown in FIG. 13, in some implementations, the method includes, at 1302, placing a first repair plate substantially flush against a pole. According to some embodiments, a first repair plate may include: a first substantially planar plate segment, a second substantially planar plate segment connected to the first substantially planar plate segment at a shoulder, the first substantially planar plate segment disposed at a first angle from the second substantially planar plate segment, a third substantially planar plate segment connected to the second substantially planar plate segment at a second angle, and a fourth substantially planar plate segment connected to the third substantially planar plate segment, the fourth substantially planar plate segment including the second side edge of the repair plate, the fourth substantially planar plate segment disposed in a substantially parallel direction to the second planer plate segment and offset from the second substantially planar plate segment by an offset distance. In some embodiments, the first substantially planar plate segment may be positioned flush against a first side of the pole, and the second substantially planar plate segment may be positioned flush against a second side of the pole, wherein the second side of the pole is adjacent to the first side of the pole. At 1304, the method can include placing a second repair plate substantially flush against the pole, wherein the second repair plate is placed adjacent to the first repair plate. According to some embodiments, the second repair plate may be placed such that: a first substantially planar plate segment of the second repair plate is positioned flush against the second side of the pole, a second substantially planar plate segment of the second repair plate is positioned flush against a third side of the pole, wherein the third side of the pole is adjacent to the second side of the pole, and the end of the first substantially planar plate segment of the second repair plate is received by the gap formed between the fourth substantially planar plate segment of the first repair plate and the surface of the second side of the pole. At 1306, the method can include affixing the first substantially planar plate segment of the second repair plate to the fourth substantially planar plate segment of the first repair plate. At 1308, the method can include affixing the first and second substantially planar plate segments of the first repair plate to the first and second sides of the pole, respectively. Lastly, at 1310, the method can include affixing the first and second substantially planar plate segments of the second repair plate to the second and third sides of the pole, respectively. In some embodiments, the repair plates may be affixed to one another or to the utility pole by using bolts, pins, screws, epoxy, adhesive, blind bolts, welding, or any other such attachment means.
As described previously above, in some embodiments, utility pole repair plates 202 may be placed around a pole such that they cover the entire perimeter or circumference of the pole. In some embodiments, this may be achieved by creating two utility pole repair assemblies that each cover half of the circumference/perimeter of the pole and then placing the two utility pole repair assemblies on the surface of the pole such that they interconnect before then joining them together, by, for example, welding them together. According to some embodiments, a utility pole repair assembly may be created by temporarily positioning a plurality of utility pole repair plates 202 against the outer wall of the utility pole, such that they are interlocking in a roughly semi-circular configuration, and then tacking the utility pole repair plates 202 together. The tacked utility pole repair plates 202 may then be removed from the exterior of the utility pole and placed elsewhere, for example, on the ground, where they may then be fully welded together at the joints. Once two utility pole repair assemblies have been created, they may both be placed back around the outer wall of the utility pole, such that they interlock with one another, and then the two utility pole assemblies may be welded to one another and the utility pole.
According to some embodiments, it may be desirable to provide additional strengthening to the two weld joints that join the two utility pole repair assemblies, as these joints may be fillet welded longitudinal joints that are only welded on one side of the connecting joint that joins a utility pole repair plate 202 of the first utility pole repair assembly with a utility pair repair plate 202 of the second utility pole repair assembly. These fillet-welded joints may not be as strong as the all of the other longitudinal joints, which may be welded on both sides. FIG. 14 illustrates the use of a weld strip 1402 to provide additional strengthening to area at which the first utility pole repair assembly 1410 is attached to the second utility pole repair assembly 1412. As described above, utility pole repair plates 202 of the first utility pole repair assembly 1410 and second utility pole repair assembly 1412 may be attached, for example, by welding, to one another as well as the utility pole 100. According to some embodiments, a weld strip 1402 may have a first substantially planar plate segment, a second substantially planar plate segment extending away from the first substantially planar plate segment at a first angle, and a third substantially planer plate segment extending away from the second substantially planar plate segment at a second angle. According to some embodiments, the first and third substantially planar plate segments may be oriented to be approximately parallel. As shown in FIG. 14, a weld strip 1402 may be positioned such that the first substantially planar plate section is adjacent to a first substantially planar plate segment of the utility pole repair plate 202a of the first repair plate assembly and the third substantially planar plate segment of the weld strip 1402 is adjacent to the fourth substantially planar plate segment of the utility pole repair plate 202b of the second repair plate assembly. The first substantially planar plate segment of the weld strip 1402 may be welded 1406 to the first substantially planar plate segment of the utility pole repair plate 202a of the first repair plate assembly 1410 and the third substantially planar plate segment may be welded 1408 to the fourth substantially planar plate segment of utility pole repair plate 202b of the second repair plate assembly 1412. As will be understood by those of skill in the art, the attachment of the weld strip 1402 may strengthen and reinforce the single fillet weld 1404. According to some embodiments, welds 1406 and 1408 may be fillet welds. Those of skill in the art will further recognize there may be alternatives methods of strengthening the connection between the first repair plate assembly 1410 and the second repair plate assembly 1412, such as, for example, welding them together with one or more slot welds and/or plug welds.
Although the previous description refers to two utility pole repair assemblies that each cover half of the perimeter of a pole, it should be understood that other proportions may be used. For example, in some embodiments a first utility pole repair assembly may cover 25% of the perimeter of the pole and a second utility pole repair assembly may cover 75% of the perimeter of the pole. Furthermore, in some embodiments, more than two utility pole repair assemblies may be used.
According to some embodiments, as shown in FIG. 15, a utility pole repair plate 1502 may have one or more joints 1504 that may enable the utility pole repair plate 1502 to be fillet-welded to another surface. The presence of the joint 1504 may allow a longer weld (by providing an additional surface of the utility pole repair plate 1502 to weld to another surface) than a utility pole repair plate 202 without the joint 1504. This increase in weld length may enable the utility pole repair plate 1502 to have a higher strength connection to a utility pole 100, which may increase the strength of the repaired utility pole 100. For example, joints 1504 may enable the utility pole repair plate 1502 to be fillet-welded to the exterior of a utility pole 100 with an increased weld along the top and bottom of the utility pole repair plate 1502. As used herein, a joint 1504 may refer to an indentation or recess in one or more substantially planar plate segments of a utility pole repair plate 1502 that extends vertically or at an angle towards the center of the repair plate 1502 from the top or bottom edge of the plate 1502 and result in a “castellated” or “scalloped” profile at the top and bottom of the plate assembly. A utility pole repair plate 1502 having such joints 1504 may be referred to herein as a “jointed utility pole repair plate” 1502. According to some embodiments, the vertical length 1512 of the first substantially planar plate segment of a jointed utility pole repair plate 1502 may be longer than the vertical length 1514 of the fourth substantially planar plate segment of the jointed utility pole repair plate 1502. In some embodiments, the third substantially planar plate segment of a jointed utility pole repair plate 1502, may have the same vertical length as the vertical length 1514 of the fourth substantially planer plate segment of the jointed utility pole repair plate 1502. It should be understood that although the difference in vertical lengths 1512, 1514 between the first and fourth substantially planar plate segments is described above with respect to a jointed utility pole repair plate 1502, any other embodiment of a utility pole repair plate described herein may include a difference in vertical length 1512, 1514 between the first and fourth substantially planar plate segments.
A jointed utility pole repair plate 1502 may be made by modifying the design of one of the utility pole repair plates described above, such as for example, the utility pole repair plate 202 described with respect to FIG. 2A, to include one or more joints 1504 as shown in FIG. 15. For example, a jointed utility pole repair plate 1502 may be a utility pole repair plate 202 (as described above with respect to FIG. 2A) that includes a joint 1504 positioned at the shoulder 205 of the utility pole repair plate 202 on the top and/or bottom edge of the plate 202. Accordingly, in some embodiments, a joint 1504 of a jointed utility pole repair plate 1502 may be an indentation or recess in a portion of one or both of a first substantially planar plate segment and a second substantially planar plate segment of a utility pole repair plate as described above. For example, a joint 1504 of a jointed utility pole repair plate 1502 may be a recess or indentation in a portion of one or both of the first substantially planar plate segment 204 and the second substantially planar plate segment 206 of a utility pole repair plate having the design of a utility pole repair plate 202 described above with respect to FIG. 2A, or any other design of a utility pole repair plate described herein. According to some embodiments, a joint 1504 may be a recess that has an approximately rectangular shape. As shown in FIG. 15, in some embodiments, a joint 1504 may be approximately rectangular with a rounded end. According to some embodiments, a joint 1504 may have an angled shape, such as a V-shape on the top edge of a jointed utility pole repair plate 1502 or an inverted V-shape at the bottom edge. It should be appreciated that a joint 1504 may have a variety of different shapes and sizes according to various embodiments, and the examples provided herein are merely illustrative. According to some embodiments, a jointed utility pole repair plate 1502 may have a joint 1504 at the top of the plate 1502, a joint 1504 at the bottom of the plate 1502, or both the top and bottom of the plate 1502, as is shown in FIG. 15.
According to some embodiments, as shown in FIG. 16, a joint 1504 may be positioned on the utility pole repair plate 1502 such that the joint 1504 may straddle a corner or vertex of a utility pole 100 when the utility pole repair plate 1502 is placed on a utility pole 100. Further, FIG. 16 illustrates that the portion of the utility pole 100 positioned underneath the joint 1504 may be viewable and/or accessible through the joint 1504 when the jointed utility pole repair plate is in use with the utility pole 100. Accordingly, the joint 1504 may provide access to one or more surfaces of the utility pole 100 such that the jointed utility pole repair plate 1502 may be fillet-welded to the utility pole 100, by, for example, welding the inner edge of the recess that makes up a joint 1504 to the surface of the utility pole 100.
As previously described above with respect to FIG. 15, in some embodiments, the vertical length 1514 of the fourth substantially planar plate segment of a jointed utility pole repair plate 1502 may be shorter than the vertical length 1512 of the first substantially planar plate segment of the jointed utility repair plate 1502. Accordingly, as shown in FIG. 16, in some embodiments, when two jointed utility pole repair plates 1502 are placed adjacent to one another on a utility pole 100, the first substantially planar plate segment of one jointed utility pole repair plate 1502 (i.e., the inner end of the joggle lap) will extend a vertical extension distance 1602 beyond the fourth substantially planar plate segment of the adjacent jointed utility pole repair plate 1502 (i.e., the outer end of the joggle lap). Although FIG. 16 only depicts the vertical extension distance 1602 at the top end of the jointed utility pole repair plates 1502, it should be understood that a similar vertical extension distance 1602 may also be present at the bottom end of jointed utility pole repair plates 1502. Because the outer end of this joggle lap joint is shorter than the inner end of the joggle lap joint, this joggle lap joint forms what may be referred to as a “stepped transition.” The stepped transition at the outer ends of the longitudinal joggle lap joint may enable fillet-welds to be made at the top and bottom of the laps. The stepped transition design of the jointed utility pole repair plate 1502 may provide the benefit of a reduced ledge at the top of the joggle lap joint, which may allow easier shedding of water. Furthermore, the stepped transition of the jointed utility pole repair plate 1502 may provide a more gradual transition to the thicker section of the joggle lap (i.e., the portion of the joggle lap joint where the fourth substantially planar plate segment of the first utility pole repair plate 1502 overlaps with a portion of the first substantially planar plate segment of the adjacent second utility pole repair plate 1502), which may have beneficial results such as a potential reduction of stress concentration(s) as forces are transferred from the utility pole 100 walls to the jointed utility pole repair plates 1502 and vice versa.
According to some embodiments, as shown in FIG. 17, a utility pole repair plate of this disclosure, such as, for example the jointed utility pole repair pole 1502 described above with respect to FIG. 15, may include one or more slot weld slots 1704 that may enable slot-welding of the utility pole repair plate 1702 to another utility pole repair plate or surface. In some embodiments, a slot weld slot 1704 may be an aperture in one of the substantially planar plate segments that make up the utility pole repair plate 1702. For example, in some embodiments, a slot weld slot 1704 may be an aperture in the fourth substantially planar plate segment that is designed to be positioned on top of a first substantially planar plate segment of an adjacent utility pole repair plate 1702, as described above with respect to the utility pole repair plate 202 of FIG. 2A. Accordingly, in some embodiments, the one or more slot weld slots 1704 may enable the fourth substantially planar plate segment of the utility pole repair plate 1702 to be slot-welded to the first substantially planar plate segment of an adjacent jointed utility pole repair plate 1502 when positioned adjacent to it, as shown in FIG. 18. Although FIG. 18 illustrates an example embodiment where a utility pole repair plate 1702 having one or more slot weld slots 1704 may be positioned adjacent to a jointed utility pole repair plate 1502 for slot-welding to one another, it should be understood that it is contemplated that a utility pole repair plate 1702 having one or more slot weld slots 1704 may be slot-welded to any other variation of a utility pole repair plate described herein and that the examples shown in the figures are merely illustrative. According to some embodiments, the slot weld slots 1704 may be used to provide welds that supplement the full length welds on the outside of a utility pole repair plate assembly when welds cannot be placed on the inside of a joggle lap joint. According to some embodiments, a weld strip, such as the weld strip 1402 shown in FIG. 14 may also be used to provide welds that supplement the full length welds on the outside of a utility pole repair plate assembly.
According to some embodiments, as shown in FIGS. 19A and 19B, a utility pole repair plate 1902 may have one or more weld tabs 1904. A weld tab 1904 may be a portion of the utility pole repair plate 1902 that projects out of an edge of one of the substantially planar plate segments of a utility pole repair plate 1902. For example, according to some embodiments, and as shown in FIG. 19A, a weld tab 1904 may be a portion of the plate the projects out of the side edge of the first substantially planar plate segment. In some embodiments, a weld tab 1904 may be positioned at a top and/or bottom side edge of the utility pole repair plate 1902. According to some embodiment, a weld tab 1904 may be substantially rectangular in shape. In some embodiments, a weld tab 1904 may be widest near the top or bottom edge of the utility pole repair plate 1902 and may eventually slope inwards towards the side edge of the utility repair plate as the weld tab 1904 gets closer to the vertical center of the utility pole repair plate 1902, as shown in FIGS. 19A and 19B.
FIG. 19A illustrates an embodiment of a utility pole repair plate 1902 having one or more joints 1906 that are similar to the joints 1504 described with respect to FIG. 15. FIG. 19B illustrates an embodiment of a utility pole repair plate 1902 having one or more joints 1906 and one or more slot weld slots 1908 that are similar to the slot weld slots 1704 described with respect to FIG. 17. It should be appreciated that the embodiments shown in the figures are illustrative only and that it is contemplated that any utility pole repair plate described herein, such as for example, the utility pole repair plate 202 described with respect to FIG. 2A, may be modified to include any combination of one or more weld tabs 1904, joints 1906, and/or slot weld slots 1908 described herein. For example, in some embodiments, the design of a utility pole repair plate 202 may be modified to include one or more weld tabs 1904 but may not include joints 1906 or slot weld slots 1908. Further, although the features of FIGS. 15-20 are typically described herein with respect to a modification of the design of the utility pole repair plate 202 of FIG. 2A that is designed to be used with an 8-sided utility pole 100, it should be understood that utility pole repair plates designed for all of the utility pole shapes and sizes described herein may be modified to include weld tabs 1904, joints 1906, and/or slot weld slots 1908. Further, hinged repair plates such as the hinged repair plate 212 shown in FIG. 2B, may also be modified to include weld tabs 1904 and/or slot weld slots 1908.
As shown in FIG. 20, according to some embodiments, a weld tab 1904a may serve to reduce the gap 1905 under the joggle lap joint between two adjacent utility pole repair plates 1902 when they are positioned for use on a utility pole 100 and the weld tab 1904a is placed in the gap 1905. As is shown by FIG. 20, the gap 1905 under the joggle lap joint between the fourth substantially planar plate segment of the first utility pole repair plate 1902a and the first substantially planar plate segment of the adjacent second utility pole repair plate 1902b may be substantially reduced by the use of the trimmed to fit weld tab 1904b when compared to embodiments without the weld tab 1904, such as the embodiments shown in FIGS. 16 and 18. Accordingly, by reducing the gap 1905, the weld tab may be useful in providing increased welding efficiency of the utility pole repair plate assembly to the pole, and may serve to decrease the potential for weld defects by minimizing the gap 1905, which would otherwise require bridging with weld. According to some embodiments, a weld tab 1904 may have a predetermined size and shape that is designed to snuggly fit in the gap 1905 under the joggle lap joint between two adjacent utility pole repair plates 1902. In some embodiments, it may be necessary to trim the weld tab 1904 in order to reduce its size to better fit in the gap 1905. Accordingly, as shown by weld tab 1904a in FIG. 20, in some embodiments a weld tab 1904 may be trimmable. For example, a weld tab 1904a may have a trimmable portion 1910 that may be trimmed or cut off by a technician to customize the size of the weld tab 1904a to the size of the joint. Accordingly, a utility pole repair plate 1902a with a weld tab 1904a may enable a technician to reduce the size and shape of the weld tab 1904a during the time of fit-up of utility pole repair plates into an assembly to create a better fit with the gap 1905 under the joggle lap joint. Weld tabs 1904 may allow for greater variance in the size range of utility poles 100 that a given set of utility pole repair plates 1902 may fit, while still allowing a minimal gap at the ends of the joints for welding. As such, weld tabs 1904 may provide a great advantage by reducing the time required to fit the utility pole repair plates 1904 together on a utility pole 100, by minimizing the material that may be needed to be trimmed off to achieve a joint with a minimal gap, and by avoiding the creation of excessive gaps that may occur between utility pole repair plates if the weld tabs 1904 were not present.
According to some embodiments, regardless of whether or not the utility pole repair plates have weld tabs 1904, it may be desirable to have a predetermined minimum length of the lap distance 1912 (shown in FIG. 20) between the fourth substantially planar plate segment of a first utility pole repair plate 1902a and the first substantially planer plate segment of an adjacent second utility pole repair plate 1902b. According to some embodiments, the dimensions of a utility pole repair plate 1902 may be such that the lap distance 1912 between two adjacent utility pole repair plates 1902 positioned on a utility pole 100 may be at least five times the thickness of the utility pole repair plate 1902 thickness. In some embodiments, the dimensions of a utility pole repair plate 1902 may be such that the lap distance 1912 between two adjacent utility pole repair plates 1902 positioned on a utility pole 100 may be at least one inch. In some embodiments, the lap distance 1912 may be at least the greater of five times the thickness of the utility pole repair plate 1902 thickness or one inch According to some embodiments, the dimensions of a utility pole repair plate 1902 may be such that the minimum length of the lap distance 1912 may be maintained along the full vertical length of the lap joint. Accordingly, in some embodiments, weld tabs 1904 that only extend the width of a utility pole repair plate 1902 for a portion of the length of the utility pole repair plate 1902a (e.g., as shown in FIG. 20), should not be considered when assessing whether a lap distance 1912 meets a particular predetermined minimum length.
