The present disclosure relates generally to pole vaults, and more particularly to forms for constructing foundations for anchoring pole vault standards adjacent to a pole vault landing area.
Pole vaulting is a track and field event in which a person uses a long, flexible pole as an aid to jump over a horizontal crossbar. A pair of pole vault standards disposed adjacent to a landing pad support the crossbar that athletes must clear during a pole vault event. Rules and regulations generally require that the pole vault standards be securely anchored to the ground or sufficiently weighted to prevent the possibility of tipping over.
Typically, each of the pole vault standards include a base and a vertical uprights for supporting the crossbar. The most common method for anchoring pole vault standards includes an exposed concrete foundation sized slightly larger than the footprint of the base, allowing for the base to be manually affixed to the concrete with appropriate hardware. By way of traditional methods, the concrete foundations are formed by hand. The size and depth are not controlled, the exposed concrete is left at the surface, and manual drilling must be carefully performed for the anchoring of the hardware. Certain hardware cannot be easily removed or replaced, for example, if epoxied into the concrete.
For a large percentage of new construction applications, the pole vault runway and landing area includes asphalt and/or concrete which is then coated with a resilient rubber track material, typically ½ inch in depth. In such cases, the aforementioned exposed concrete foundations often represent the only hard and unyielding surface in the pole vault event area. In cases where the concrete foundations are recessed ½ inch to allow for coating of the rubber surface, it is then difficult to properly locate the foundations prior to manually drilling and anchoring the hardware. Furthermore, doing so not only risks damage to the newly laid and highly expensive track surface, but creates recessed cavities where water can collect allowing for potential damage in the future as a result of freezing and thawing.
Shortcomings of the prior art are overcome and additional advantages are provided through the provision, in one embodiment, of a method for forming a first foundation and a second foundation adjacent to a pole vault landing area for anchoring a base of first pole vault standard and a base of a second pole vault standard. The method includes excavating a first portion of the support structure adjacent to one side of a pole vault landing area, excavating a second portion of the support structure adjacent to an opposite side of the pole vault landing area spaced from the excavated first portion of the support structure, providing a first form in the excavated first portion of the support structure, the first form includes a first frame and a first plurality of connectors defining a first connecting pattern for coupling to a corresponding connecting pattern of the first pole vault standard, providing a second form in the excavated second portion of the support structure, the second form includes a second frame and a second plurality of connectors defining a second connecting pattern for coupling to a corresponding connecting pattern of the second pole vault standard, placing uncured cement in the excavated first portion of the support structure and curing the cement to secure the first frame and first plurality of connectors to the support structure, wherein the first plurality of connectors is alignable with the corresponding connecting pattern of the first pole vault standard and operable for use in fixedly securing the first pole vault standard adjacent to the one side of the pole vault landing area, and placing uncured cement in the excavated first portion of the support structure and curing the cement to secure the second frame to the support structure, wherein the second plurality of connectors is alignable with the corresponding connecting pattern of the second pole vault standard and operable for use in fixedly securing a second pole vault standard to the support structure adjacent to the opposite side of the pole vault landing area.
In another embodiment, a pair of forms for constructing a first foundation and a second foundation for anchoring a first pole vault standard and a second pole vault standard to a support structure adjacent to a landing pad is provided. The pair of forms includes, for example, a first form having a first frame and a first plurality of connectors defining a first connecting pattern for coupling to a corresponding connecting pattern of a base of the first pole vault standard, and wherein the first form is fixedly installable in the support structure and operable for use in fixedly connecting the first base of the first pole vault standard to the first form, and a second form having a second frame and a second plurality of connectors defining a second connecting pattern for coupling to a corresponding connecting pattern of the second pole vault standard, and wherein the second form is fixedly installable in the support structure and operable for use in fixedly connecting a base of a second pole vault standard to the second form.
The subject matter which is regarded as the disclosure is particularly pointed out and distinctly claimed in the concluding portion of the specification. The disclosure, however, may best be understood by reference to the following detailed description of various embodiments and the accompanying drawings in which:
The present disclosure and certain features, advantages, and details thereof, are explained more fully below with reference to the non-limiting embodiments illustrated in the accompanying drawings. Descriptions of well-known materials, fabrication tools, processing techniques, etc., are omitted so as to not unnecessarily obscure the disclosure in detail. It should be understood, however, that the detailed description and the specific examples, while indicating embodiments of the present disclosure, are given by way of illustration only, and are not by way of limitation. Various substitutions, modifications, additions and/or arrangements within the spirit and/or scope of the underlying concepts will be apparent to those skilled in the art from this disclosure. Reference is made below to the drawings, which are not drawn to scale for ease of understanding, wherein the same reference numbers used throughout different figures designate the same or similar components.
The present disclosure as described further below is directed to a pair of prefabricated, stay-in-place pole vault standard foundation forms that allow for easy installation and anchoring of pole vault standards. The foundation forms are operable for use in a support structure such as the ground or an asphalt layer and underground or beneath a track or artificial turf in an athletic field. The foundation forms may be prefabricated under manufacturing conditions thereby assuring accuracy and economy. The foundation forms can be readily transported and installed to produce a pair of foundations for anchoring pole vault standards that is permanent and economical. The foundation forms may include a pattern of connectors aligned with and readily connectable to a corresponding pattern of connectors in the bases of the pole vault standards.
Landing pad 20 may include a main landing pad section 22 disposed behind crossbar 50, and a pair of spaced apart tapered pad sections 30 and 32 disposed in front of crossbar 60 and along sides of planting box 70.
Main landing pad section 22 may include main padding member 21 and a main cover 23 covering main padding member 21. The material forming main padding member 21 may include a suitable polyurethane foam core and may include different layers. Main cover 23 may be formed from a non-porous vinyl material. For example, main cover 23 may be an 18-ounce heavy coated vinyl polyester that has high tear and tensile strengths. Landing pad 20 may include a 2-inch top pad 27 disposed on top of main landing pad section 22 and tapered pad sections 30 and 32 to protect the upper surfaces of main landing upper padding section 22 and tapered pad sections 30 and 32. Top pad 27 may include a padding member 28 and a cover 29. The top pad may be a foam pad which is covered with heavy-duty vinyl coated polyester mesh that is ultraviolet and spike resistant.

In this illustrated embodiment, the bottom peripheral portions define a first opening 260 and a second opening 262. The first and second major bottom peripheral edge portions and the first and second minor bottom peripheral edge portions may be disposed at right angles to each other to define a plurality of corners (not shown).
As shown in
Top plate 210 along first major top peripheral edge portion may be provided with a downwardly depending tab or lip 219 (best shown in
In some embodiments, the top plate, the bottom plate, and the spacers may be formed from aluminum or other suitable metal or other material. In some embodiments, the spacers may be C-channels such as aluminum C-channels. The various components of the first frame may be suitable riveted, bolted, welded, or otherwise suitably assembled and connected together. In other embodiments, for example, a bottom plate and the first and the second outer spacers may be integrally formed as a monolithic structure. For example, peripheral minor sides of the bottom plate may be bent upwards to form first and second spacers. While the first frame may include a single cross member between two openings in the top plate and bottom plate, it will be appreciated that the top and bottom plates may include one (no cross member) or more than two openings with cross members disposed therebetween. Other variations of the placement of the openings and cross member may be suitable employed. The spacers may provide sufficient rigidity to the frame.

In other applications, the entire footprint of the pole vault area/pad is constructed with monolithic concrete so that foundation form 900 would be set within a larger hand-formed area in which the uncured concrete gets poured at once. In such a case, rather than the sides of the form acting as a dam, the two slats may be removed so the uncured concrete can flow unrestricted.
From the present description, benefits of the present disclosure include forming systems that may provide a quality control in lieu of forming by hand, ensuring proper size and depth, allowing for a resilient rubber coating, and providing predetermined and reusable anchoring points which may be located visually at the finished surface elevation with minimal exposure. An end user may benefit from hardware flexibility if the base needs to be shimmed/leveled; i.e., the bolt depth can be altered while maintaining security, as compared to concrete wedge/expansion anchors that rely on the depth of the bolt for proper engagement. Furthermore, the end user may have the ability to fully remove the bolts if not in use, and may replace the bolts should they rust or wear, both characteristics being in contrast to conventional foundations having epoxied threaded rods which would be left protruding from the surface should the pole vault equipment be moved or temporarily placed into storage.
