This invention generally relates to the field of pole supports, specifically including, without limitation, precast concrete pole support bases and methods of manufacture, installation and use.
A wide variety of poles and posts are used throughout the world, including lighting poles, electrical, telephone and cable supports and numerous other poles of many different types. Some of these poles are installed by placing a portion of the lower end of the pole in a hole in the ground and filling the remaining space in the hole with soil, concrete or another suitable material. Many wooden poles are installed using this method in which a portion of the pole is buried in the ground. Other poles and similar structures are intended for installation with the lower end of the pole resting on a separate base, the top of which may be positioned at ground level or above ground level. Metal lamp posts are but one of many such poles, posts and other structures frequently installed on a separate, typically concrete, base.
Many poles or posts intended for installation on top of a base or support have attached to the bottom of the pole a horizontal square flange or other structure with a “square” or “rectangular” arrangement of four holes, with one hole near each of the four corners of the flange or other structure. This provides four fastening holes arranged at the corners of a square so that each hole is equally distant from each of the other two holes adjacent to it. Each of the holes may be located, for instance, in a foot or boss protruding from the side or end of the pole or a flange secured to the lower end of the pole.
Such a pole is typically installed by securing the flange or other pole-terminating structure with four studs, bolts or other fasteners: (a) protruding vertically from the concrete base and up through the flange or other structure or (b) passing down through the holes in the pole base plate or other structure and into the concrete base. Where studs, pins, bolts or the like are positioned to be received in the holes in the pole base plate or other hole-containing structure, the fasteners must be located carefully during preparation of the base or foundation in order to insure that the fastener spacing matches the locations of the holes in the pole flange or other hole-containing structure. Each stud, pin, bolt or the like is usually the upper end of a long rod or is attached to such a rod or other anchor that extends well down into the base or foundation on which the pole is to be installed.
Many pole bases are designed for a specific pole mounting configuration and are not compatible with any other pole mounting configurations. Further, if one or more studs protruding from a concrete base is sheared off, as often happens when a motor vehicle collides with a pole mounted on such a concrete base, replacement of the pole may be difficult because of the difficulty of attaching new studs to the concrete base.
In certain situations, it may be desirable for a pole base to include a robust modular mounting system capable of accepting various fastener sizes and compatible with various pole flange configurations.
The terms “invention,” “the invention,” “this invention” and “the present invention” used in this patent are intended to refer broadly to all of the subject matter of this patent and the patent claims below. Statements containing these terms should be understood not to limit the subject matter described herein or to limit the meaning or scope of the patent claims below. Embodiments of the invention covered by this patent are defined by the claims below, not this summary. This summary is a high-level overview of various aspects of the invention and introduces some of the concepts that are further described in the Detailed Description section below. This summary is not intended to identify key or essential features of the claimed subject matter, nor is it intended to be used in isolation to determine the scope of the claimed subject matter. The subject matter should be understood by reference to appropriate portions of the entire specification of this patent, any or all drawings and each claim.
According to certain embodiments of the present invention, a pole base provides a secure mounting structure that can easily be adapted to multiple configurations of poles. The pole base may include a body having an upper portion and a pole attachment device disposed on the upper portion of the body. The pole attachment device may include a plate configured to removeably receive a plurality of fasteners such that each of the plurality of fasteners may be received in the plate in a plurality of locations.
The subject matter of embodiments of the present invention is described here with specificity to meet statutory requirements, but this description is not necessarily intended to limit the scope of the claims. The claimed subject matter may be embodied in other ways, may include different elements or steps, and may be used in conjunction with other existing or future technologies. This description should not be interpreted as implying any particular order or arrangement among or between various steps or elements except when the order of individual steps or arrangement of elements is explicitly described.
Disclosed herein is a pole base 100 configured to support a pole 200. Specifically, as shown in
As shown in
The fasteners 106 may be adjusted in the radial direction within the slots 102 to adapt to various arrangements of pole flanges 201 (see
In this way, the slots 102 of plate 101 are configured to permit each fastener 106 to be secured in a variety of locations relative to the plate 101 such that the plate 101 can be adapted to secure multiple types and configurations of poles 200 to base 300. Specifically, the plate 101 is able to accommodate the various bolt patterns for pole flanges 201 that depend on the size and configuration of pole 200.
In addition, separate plate 101 is compatible with various fastener sizes used for different flanges 201.
As shown in
As shown in
As shown in
When the body 300 is partially or fully buried in a ground hole (the pole base 100 may be installed such that up to three feet of the body 300 projects above ground level), the anti-rotation cavities 305 ensure that the soil/earth surrounding the ground hole interacts with a non-smooth surface such that backfill and/or soil/earth fills the anti-rotation cavities 305 to prevent the pole base 100 from rotating within the ground hole.
To ensure proper dimensions and profiles of the recess 302 and central cavity 303 of the body 300, a sacrificial void-forming device 400 may be used when molding the body 300 (e.g., during a concrete molding process). As shown in
As shown in
During installation of a pole base 100, once the pole base 100 is on site and an appropriate hole has been excavated, the pole base 100 must be lifted into the hole. To simplify and facilitate proper and balanced lifting, the pole base 100 may comprise a lifting device 500 as shown in
In another embodiment, as shown in
The foregoing is provided for purposes of illustrating, explaining, and describing embodiments of the present invention. Further modifications and adaptations to these embodiments will be apparent to those skilled in the art and may be made without departing from the scope or spirit of the invention. Different arrangements of the components depicted in the drawings or described above, as well as components and steps not shown or described are possible. Similarly, some features and subcombinations are useful and may be employed without reference to other features and subcombinations. Embodiments of the invention have been described for illustrative and not restrictive purposes, and alternative embodiments will become apparent to readers of this patent. Accordingly, the present invention is not limited to the embodiments described above or depicted in the drawings, and various embodiments and modifications can be made without departing from the scope of the claims below.
