Abstract
The structural characteristics of standing poles are enhanced or preserved, or changed to provide break-away characteristics, by a technique which includes forming one or more sheets about the pole. The sheets are defined by an outer jacket, a plurality of spacer members positioned within the jacket and a solidified encapsulating material which fills the jacket.
Claims18
A method of enhancing the characteristics of a standing pole comprising the steps of:
- supporting a plurality of elongated spacer members about a portion of the exterior surface of a pole, the spacer members being oriented substantially in parallelism with respect to one another;
- wrapping a first pliable sheet around the supported spacer members, the sheet having a first substantially straight edge;
- marking the first sheet along a line adjacent to the overlapping of the said first edge;
- removing the first sheet and severing the said first sheet along the marked line to form a second edge disposed oppositely and parallel to said first edge;
- rewrapping the severed sheet around the supported spacer members and forming a leak-proof joint in the vicinity of said first and second edges, the rewrapped sheet defining a cavity about the pole, the spacer members being disposed in said cavity;
- forming a pouring funnel about the pole with a second sheet of material, the smaller end of said funnel being disposed between the pole and said first sheet;
- pouring an encapsulating material comprising an epoxy resin into the cavity via the funnel whereby the encapsulating material contacts and encapsulates the pole along the length of the cavity;
- and
- removing the funnel subsequent to the pouring of said encapsulating material.

A method of fabricating a break-away pole comprising the steps of:
- supporting a plurality of elongated spacer members about a portion of the exterior surfaces of each of upper and lower abutting pole sections, the spacer members being oriented substantially in parallelism with respect to one another;
- wrapping first pliable sheets around the supported spacer members, the sheets each having substantially straight edge first edges;
- marking each of the first sheets along a line adjacent to the overlapping of its first edge;
- removing the first sheets and severing them along the marked lines to form first sheet second edges disposed oppositely and parallel to said first edges;
- rewrapping the severed sheets around the supported spacer members, the rewrapped sheets defining cavities about the pole sections, said cavities extending along the pole sections from the abutting ends thereof, the spacer members being disposed in said cavities;
- affixing a plurality of generally L-shaped brackets to said upper and lower pole sections, said brackets being in registration on the sections and abutting the cavity defining sheets, the brackets on the upper pole section being oriented oppositely with respect to the brackets on the lower pole section;
- forming a first pouring funnel with another sheet of material, the smaller end of said first funnel being disposed between the lower pole section and its jacket;
- pouring an encapsulating material comprising an epoxy resin into the cavity via the first funnel whereby the encapsulating material contacts and encapsulates the lower pole section along the length of the cavity;
- removing the first funnel subsequent to the pouring of said encapsulating material;
- joining said brackets to one another by a fastening system which will release in response to an impact directed transversely to the pole axis;
- forming a second pouring funnel about the upper pole section from sheet material, the smaller end of said second funnel being disposed between the upper pole section and its jacket;
- pouring the encapsulating material into the cavity about the upper pole section via said second funnel whereby the encapsulating material contacts and encapsulates the upper pole section along the length of the cavity;
- and
- removing the second funnel subsequent to the pouring of the encapsulating material.
