PANEL MEMBER

CROSS-REFERENCE TO- RELATED APPLICATION

I he present application claims priority irom Australian Provisional Patent Application No. 2011900189 filed on 21 January 2011, the contents of which are incorporated herein by reference.

FIELD OF INVENTION

The present invention relates to a panel member lor use in the construction of buildings, walls and the like. More particularly, the present invention relates to a multi-purpose panel member formed in a manner and having sufficient strength and impact resistant properties for use across a variety of applications.

BACKGROUND ART

There erist a variety of pre-fabricated panels for use in building structures and the like. Most such pre-fabricated panels arc made Irom concrete, cement sheeting, wood or the like, that are positioned during the construction of a structure and secured in place.

Many structures have walls, both interior and erterior, that have the potential to erperience various degrees of impact, depending on the specific application for which the structure is used. Such impact may result from people, animals, vehicles, machinery and the like contacting the surfaces of the wall with varying degrees of force. Depending on the structure of the wall, sufficient impact forces can cause damage to the wall which can have a particular displeasing aesthetic effect on the building structure. Further, due to the rigid nature of most prefabricated walls used in building construction, any sufficient contact with the wall can cause damage or harm to the person, animal, vehicle or the like that may cause such impact

In the field of animal management, in particular the handling of horses and the like, il is of considerable importance to accommodate a horse in a safe, controlled environment. This is particularly the case in the field of horse racing where horses are valuable commodities and arc prepared and trained to high levels with significant care and erpertise, and at significant cost. In such instances, horses arc typically accommodated in stables whilst undergoing training to reduce injury and to control their feed intake and behaviour. Hence it is important that when a race horse is stabled, the likelihood of injury to the horse is reduced. Typically, most stables constructed to accommodate race horses and the like employ timber or a combination of timber and steel sheeting, such as that sold under the trade mark Colorbond® by BluScope Steel Limited. As a result, the walls of such stables are relatively rigid and offer lillle in the way of impact absorption or impact resistance. As horses, in particular thoroughbred race horses, have a tendency to. kick when in closed confines or when agi luted, stable walls may be regularly damaged which con be costly in terms of replacing such walls and may result in the stable becoming aesthetically displeasing. Further, due to the rigid nature of the walls of most stables, should a horse kick with significant force, the horse may become injured due to the force of the impact, or due to the wall becoming damaged and cutting the animal. This could have serious detrimental impact on the career of a race horse.

As a result there is a need to provide a wall structure that can be employed in a variety of instances where impact load against the wall is likely. Such a wall structure provides significant resistance to damage occurring to the. wall as well as provides a degree of impact absorption.

There is also a need to provide a panel member that has a structure and weight that is easy to install to form a wall in a quick and efficient manner.

The above references to and descriptions of prior proposals or products are not intended to be, and are not to be construed as, statements or admissions of common general knowledge in the art. in particular, the above prior art discussion does not relate to what is commonly or well known by the person skilled in the art, but assists in the understanding of the inventive step of the present invention of which the identification of pertinent prior art proposals is but one part.

DETAILED DESCRIPTION OF THE DRAWINGS

Preferred features of the present invention will now be described with particular reference to the accompanying drawings. However, U is to be understood that the features illustrated in and described with reference to the drawings arc not to be construed as limiting on the scope of the invention.

The present invention will be described in relation to its application for use in horse stables to prevent injury to horses and damage to stable walls. However, it will he appreciated that the present invention has application to a variety of uses other than stables, such as horse iloals and er terior walls for pens and corral, as well as other non-animal related applications as will be apparent by those skilled in the art.

Referring to Figure 1, a wall structure 5 in accordance wilh one embodiment of the present invention is shown. Wall structure 5 comprises a plurality of panel members 10 arranged in an abutting manner to form a substantially planar rectangular wall structure having a pair of opposing wall surfaces 12, 14.

Figure 2 shows a lop view of a preferred embodiment of a section of the wall structure 5 of Figure 1, namely a panel member 10 having a plurality of ribs 16 provided between the opposing surfaces 12, 14 which ertend in a parallel manner longitudinally along the panel member 10. As is evident from the figures, the ribs 1.6 that are located at the edges of the panel member 10 act to form an edge of the panel 10, to assist in arranging panels in an abutting nature during assembly, as will be described in more detail below.

It will be appreciated lhal, when formed, the panel member 10 comprises a plurality of hollow channels IS that ertend in a parallel manner along the length of the panel 10 and resultant wall structure 5. Each rib 16 is separated a distance "X" from an adjacent rib 16 such that each channel 18 is substantially identical in form and structure when compared to an adjacent channel of the panel member 10. In a preferred form, the distance "X" is around 60mm, however, other distances are also envisaged depending the specific application of use of the panel 10.

Each channel 18 is defined by an adjacent pair of ribs 16, each of which have a substantially straight or flat surface and a pair of opposed end walls 19, (hat each have a concave configuration with respect to the inner region of the channel 18. Due to the configuration of the end walls 19, the surfaces 12 and 14 of the panel member 10, and resultant wall structure 5, take cm a substantially corrugated configuration defined by a series of peaks and troughs ertending over the surfaces 12, 14 of the panel member 10, as is shown in Ktg. 1.

I nc width "/." of the panel member 10 at the edges thereof is defined by the ribs 16. Due to the concave structure of the end walls 19 of each channel 18, the width of the panel member 10 changes across the breadth of the panel member 10 to a marimum width "V located at a central point of each channel 18, as is shown in Figure 2. In a preferred form, the marimum width "Y" of the panel 10 is around 70mm, but may vary between 50 - 80 nun with the width "7," at the edge of the panel 10 being around 64mm, but which may vary between 40 - 70mm. Such an arrangement defines the corrugation of the surfaces 12, 14 having a trough-to-pcak distance of around 3mm, but which may vary between 2 - 8 mm. It will be appreciated that the above dimensions arc only illustrative of a preferred embodiment and arc not limiting to the present invention.

Each panel 10 is manufactured from an ertrusion process to ensure that each panel 10 has a continuous, repeatable shape. In this regard, each panel 10 is made from high density polyethylene (HDPE) which is a material having good tensile strength and impact resistance and is low in cost. Such a material also enables ertrusion, to ensure that the panels are able to adopt a continuous 2D profile. The material may be treated with fire relardanl material to improve the lire rating of the wall thus constructed.

In a preferred form, the width "W" of the walls of the ribs 1 and the surfaces 12 and 14 arc substantially uniform, preferably around 5mm, however other widths or thicknesses are also envisaged. It will be appreciated that the panel members 10 of the present invention may be made from any crtrudablc polymeric materials including elastomeric materials and still fall witliin the spirit of the present invention. Further, it will be appreciated that rather than the panel member 10 of the present invention being made from a single material, the panel member may. be made from a plurality of materials by way of co-crtmsion manufacturing techniques. In such an arrangement, the surfaces 12, 14 of the panel member 10 may be formed to have different material properties and may be made from materials with different colour characteristics. Alternatively a separate material may be coertruded over the surfaces 12, 14 of the panel member following or during formation of the panel member 10 to provide form a variety of purposes, such as additional UV protection. Other applications of such cocrtrusion practices envisage the er trusion of a small seal in a region of the panel member where panels join together to facilitate sealed connection of panels for such purposes as water storage and retention, as will be discussed in more detail below.

Referring to Figures 3 and 4, there arc shown profiles of alternative embodiments of the panel member 10. in the embodiment shown in Figure 3, rather then the channels 18 being formed between two opposing concave end walls 19, the channel 18 is formed between a concave end wall and a conver end wall. In the embodiment shown in Figure 4, the channels 18 of the panel 10 have a substantially rectangular shape with the end walls 19 being predominately straight. In this embodiment, the end walls 19 are stepped or offset from an end wall of an adjacent channel 18 to form an outer surface 12, 14 of the panel 10 having a stepped configuration. It will be appreciated that other configurations of how the channels 18 may be constructed are also envisaged.

The embodiment of the panel member 10 shown in Figure 2 is a preferred embodiment, as it has been found that the outward corrugation of the surfaces 12, 14 of the panel 10 provide particular benefits in relation to impact resistance and impact absorption. As the peaks of the corrugation arc the first to erperience contact in an impact situation, such as a situation when a horse's hoof contacts the surface 12, 14 of the panel 10, the corrugated nature of the design allows the walls 19 of each channel 18 to absorb some of the initial impact load as it deflects before the load is transferred into the main ribs 16 of the panel 10. As the main ribs 16 of the panel 10 have a mar imum depth of around 70 mm, this provides significant resistance to further deflection of the panels, as may occur between support posts of a building structure.

Such an arrangement has an ability to reduce the effects of impact injury to the horse as well as maintaining the structural integrity of the panel member 10.

Further, the corrugated nature of the panel members resembles a more conventional corrugated sheeting surface that is typically used in horse stables and provides an aesthetic look that resembles conventional materials.

It will be appreciated that the panel members 10 may be formed to assume any desired sizes and dimensions. For instance, the panel members may be formed in a variety of standard sizes in accordance with their intended use. In this regard, the panel members 10 may be formed in sizes having widths ranging lirom 150mm - 2400mm and heights or lengths ranging from 60mm - 2400mm. It will be appreciated that due to the manufacturing method of ertruding the panels, the sizes in which the panels 10 arc formed can be varied quite simply.

Referring to Figure 5 there is shown an embodiment of a horse stable 20 incorporating the panel members 10 of the present invention. Tn this figure, for reasons of clarity, the panels 10 are shown as a single panel having a flat surface: However, as will be appreciated by the discussion above, each panel 10 depicted may comprises a plurality of individual panels abutted together, with each panel having the tertured or corrugates surface as previously discussed.

As is shown, in the structure 20, the panel members 10 are assembled to form a periphery of the structure. The structure 20 comprises a roof 21 that is supported atop four walls. The front wall comprises a door 22 that permits access to and from the interior of the structure 20. The upper region of the front wall may be typically formed in an open manner to facilitate access of light and air into the interior of the structure and may comprise open bars 23 as shown. The lower region of the front wall is formed from the panels 10 of the present invention. In this regard, the panels 10 are provided in the regions of the structure 20 where a horse may kick, should the horse become agitated or the like.

In this regard, the surfaces 12, 14 of the panels 10 form the inside surface and erterior surface of the structure respectively. It will be appreciated that the structure 20 may also be configured such that an erternal skin may be provided over the panels 10, depending upon aesthetic requirements and cost issues, in the instances where the panels 10 also function as the erterior surface of the structure 20, such as is shown in Figure 5, the HOPE material of the panels 10 may include UV stabilizers and may be coloured in accordance with user requirements. This will add to the natural capacity of HDPE to erhibit erceptional weathering properties.

As individual panel members 10 arc constructed to have a common configuration, in order to join adjacent panel members 10 in a structure a simple H-bcam system as shown in Figure 7 may be employed. In this embodiment of the invention, the widlh of the panels 10 is sufficient sudh that the edges of the panels abut against the webbing of the H-beam 25 in Ihe manner as shown. An alternative embodiment for joining adjacent panels 10 is shown in Figure 6. Tn this embodiment the same concept of employing an H-beam 25 is shown with the erception being that a rebate is formed on the outer surface 12, 14 of the panels 10 to provide a flush filling with the I I-beam 25. Such an arrangement may provide a more aesthetically pleasing connection between adjacent panels and the rebate may be incorporated into Ihe ertrusion process. In any regard, the inherent structure of the panels provides lor a simple means for connecting adjacent panel members 10 together by way of a structural member such as an H-beam 25. The H-beam is also able lo provide support for the panel members 10 along the edges thereof. As is shown in Figure 8, in order to provide optional aesthetic benefits a cap member 26 may be fitted over the H-beam 25, as desired. Whilst the panel member 10 is shown having a straight surface 12, 14 for sake of simplicity, it will be appreciated that the surfaces may be contoured in the manner as shown in

Figure I and 2.

it will also be appreciated that the ertruded nature of the panel members 10 enables a variety of different options for interlocking the edges of adjacent panels 10. In figures 9 and 10 u chamfered joint and a pecked joint is shown respectively. Tn this regard, the panel members may be ertruded to have end edges thai slot together or inierengage, such as through the use ol^" complementary edges that form lap joint, slotted joint, kcyway joint, wedge joint, or the like, thereby reducing the need for a large number of support beams to connect adjacent panel members. It will he appreciated that in. such arrangements whereby the end edges of adjacent panels engage, stake members, reinforcing rods or the like may be employed to provide additional structural support lo the panels, by inserting such slake members through the channels 18 formed in the panel members 10.

One particular arrangement for connecting adjacent panels 10 together is shown in Figure 17. In this embodiment of the present invention the panel members 10 arc formed to have a male mating member 50 formed along one edge thereof, and a corresponding female mating member 52 formed along an opposing edge thereof. The male mating member 50 is configured to be received within the female mating member 52 of an adjacent panel member to form a secure join 53. The join 53 may be sullicienliy waler light or may have seals provided therein to facilitate use of the panel members 10 in a levee wall application, as will be discussed in more detail below.

In Ihe siruclure 20 of Figure 5, in order to ibrm a comer, the panel members 10 may be easily fitted to channels formed in a corner post 30 in the manner as shown in Figures 11 and 12. In Figure 11, the panel members 10 are configured with a rebate at the edges thereof in the manner described above in relation to f igure 6. It will be appreciated that a variety of systems may be employed for connecting panel members 10 through 90° that fall within the spirit of the present invention.

When used in a building structure such as that shown in Figure 5, the panel members 10 of the structure 20 present a surface to a horse or the like, accommodated within the structure, that has a high degree of impact resistance and load absorption should the horse attempt to kick the panel. This reduces the likelihood of serious injury occurring to the horse and damage to the structure thus reducing costs associated with maffllaining and repairing the structure.

As the panel member 10 is made from HDPE, the material yield strength is appror imately 25 pa and whilst erceeding the yield strength of the material may result in some material deformation of the panel member, this typically manifests as bruising, whitening or denting of the material in the vicinity of the load application. Thus, even when the yield strength of the panel has been erceeded, there is a low likelihood of panel fracture or shattering as is commonly the case with more rigid and conventional building materials.

Whilst the panel members 10 of the present invention have a specific application for impact resistant wall surfaces as described above, due to the structure and nature of the panel members 10, they are also applicable for use in a variety of alternative applications.

One alternative application is shown in Figures 13 and 14. Tn this application, the panel members 10 are assembled to form a water wall 30. A water wall 30 is a wall or structure capable of holding and/or storing water within the panels 10. As such, the hollow nature of the panels 10 and the multiple channels provided in the panels 10 are utilised to provide conduits to receive and direct, the flow of water within the wall 30.

The panels 10 are assembled together in the manner described previously such that they abut together and arc connected between vertical supports 34. The vertical supports 34 are in the form of I-beams; however other support members arc also envisaged.

The upper and lower ends of each panel is scaled by a cap member 32 as shown. The cap member 32 is configured to lit over the ends of the channels 18 of the panel members to provide a seal thereon. The cap members 32 also provide a common fluid rail connecting each of the channels 18 at a lower and an upper region thereof to facilitate flow of water between adjacent panel members 10 and between adjacent channels 18 in each panel member 10. It will be appreciated that additional materials such as lip seals, scaling beads, and the like may be employed to seal the joints between panels.

Each cap member 32 has a hole or recess 31 formed at an end thereof to receive a connector 33 that provides a sealed connection with a recess 10 on an adjacent cap member 32. In this regard, an end panel 10 of the wall 30 may be connected to a water source, such as a slormwulcr drain or water connection system to receive water ailer which it is distributed between the panel members 10 of the wall system 30 via the interconnecting cap members 32.

In the embodiment as shown in Figures 13 and 14, the wall 30 may form a dividing wall or fence on a property or may be employed within a structure of a building, such as a shed, house or the like, and as such the surface of the walls may be coloured for aesthetic purposes.

Referring to Figures 15 and 16, yet another embodiment of the present invention is shown. In this embodiment, the panel members 10 of the present invention arc employed to form a retaining wall 40. Once again, for reasons of clarity, the panel members 10 arc shown as a single member. However, it will be appreciated that the panel member 10 as depicted may comprise a plurality of panel members 10 arranged in abutting fashion, as is clearly described in the body of the present description.

The retaining wall 40 comprises a plurality of supports 44, such as I-beams between which individual panel members 10 arc supported in the manner as shown in relation to Figures 6 and 7. The punel members 10 each have a cap member 42 that tits over an upper region thereof to form ant upper surface of the wall 40. The cap members 42 between adjacent panel members 10 interconnect to form a continuous upper surface of the wall 40.

To provide additional structural support to the wall 40, one or more stake members 46 may be inserted through the channels 18 of the panels to project beyond the lower surface of the panels to engage with a ground surface. The number of slake members 46 used to support the wall 40 can be adjusted depending upon the specific application of the wall 40 and the forces that the wall may erperience in use. Referring to Figures 18 - 20, a preferred embodiment of the present invention is disclosed.

In Figure 18, panel member 110 is depicted. Panel member 110 is in the form of a relatively narrow panel member of appror imately 150mm in width and having a configuration substantially as shown and described in relation to Figure 2. The panel member 110 comprises two channels 118 that ertend along the length or height of the panel member 110, separated by a rib member 116, such that the panel member 110 is a two-channel panel member. The panel member includes a front face 114 and a rear face 112 that present a corrugated or undulating surface, in the manner as previously described.

Formed along opposing ends or longitudinal edges of the panel member 110 is an end member 120 having a male connector 150 and an end member 122 having a female connector 152, which are depicted more clearly in Figure 19. The male connector member 152 is in the form of a projection that projects beyond a longitudinal edge of the panel member 110 and has ridges 151 formed along opposing lateral sides thereof. The female connector 152 is in the form of a recess formed along the opposing longitudinal edge of the panel member 110. The depth of the recess of the female connector 152 is substantially equivalent to the depth of the male connector member 150 to receive the male connector member 150 therein. The female connector 152 has a narrow opening formed by a pair of flange members 153. An ertended lateral recess 154 is formed immediately behind the flange members 153. The narrow opening formed by the flange members is sufficient to receive the leading edge of the male connector member 150 when a male connector member 150 of an adjacent panel member 110 is inserted into the female connector 152. However, due to the presence of the ridges 151 on opposing sides of the male connector member 150 the flange members 153 contact the ridges 151 to prevent further sliding of the male connector member 150 into the female connector 152. Due to the inherent flexibility and resilient nature of the materials of the panel member 110, as discussed previously, by applying pressure to the panel member 110 the male connector member 150 can be forced into the female connector with the flange members 153 flering to permit the ridges 151 to enter into the female connector, to create a snap fitting of adjacent panels together. The degree of force required to fit adjacent panel members 110 together in this way will largely be determined by the amount the size of the ridges 151 formed above the surfaces of the male connector member 150. In this regard, the degree of force should be sufficient to ensure a flush fit between adjacent panel members 10. Refcrring to figure 20, an alternative form of the male connector member 150 is shown. In this embodiment the male connector member 150 is formed with a pair of wing projections 155 rather than ridges 151. The wing projections 155 are shaped and configured to be received within the er tended lateral recess 154 to ensure a more secure connection between adjacent panel members 110. It will be appreciated that in order to form a wall 105 structure by lilting adjacent panel members 110 having the male connector member 150 of Figure 20, panel members 110 are slidingly assembled either vertically, as shown in Figure 22, or horizontally, as shown in Figure 23. It will be appreciated that the different conJigurations of the male connector member 150 as shown in Figures 19 and 20 provide for either snap fitting or sliding li lting of adjacent panel members 110, depending upon the required application.

A wall structure 105 employing multiple panel members 110 is shown in Figures 21 - 24. As is clear, the wall structure 105 provides a degree of inherent lleribilily between panel members 110, however, each individual panel members 110 arc scaliogly connected to an adjacent panel member through the unique male-female connection. Thus, the wall structure 105 formed by connecting the panel members 110 provides for a internal surface 114 which is sealed and isolated from the er ternal surface 112 to provide a barrier for water, air and the like to pass through the wall structure 105. It will be appreciated that a silicone sealant may also be applied along the joins between the adjacent panels 110, if required.

As depicted in Figures 22 and 23, the wall structure 105 can be formed with cither the panel members 110 ertending vertically or horizontally. Such a wall structure can be equally applied to a structure such as a horse stable 20 as depicted in Figure 5, by merely assembling the individual panel members 110 together and fitting them within channelled supports ertending along the base and the top of the wall structure 5. If further structural support is required, one or more reinforcing rods may be passed through one or more channels 118 in the panel members 110, as required.

It will be appreciated that due to the interlocking nature of the panel members 10, 110 and the complimentary size and shape of the panel members 10, 110, the wall structure 5, 105 can be used for a variety of purposes other than as a building wall or a retaining wall. In this regard, the wall structure could be assembled as a temporary wall for large events such as conceits, sporting events, and the like, where the ease or erecting and dismantling the wall offers significant advantages.

Further, the wall may be used as a levee bank or wall for flood regions, where the intcrlocking nature of the panel members provides a sealed wall that prevents water irom passing therethrough. In this regard, the wall may be supported solely by stake members to ertend along a perimeter of a region to be protected.

Due to the hollow nature of the panel members 10, 110, the wall structure created therefrom can also enable the panel members 10, 110 to be filed with concrete, cement, sand, soil and other types of material to provide additional support and structure to the wall. The open ends of the channels may also be filled with soil lor use as planter bores and the like, to add additional functionality to a building construction.

It will be appreciated that the simple structure of the panel members 10 of the present inventinn enable them to be employed in a variety of situations and applications where temporary or permanent wall structures arc required. As the panel members can be readily manufactured to snugly fit together in a sealed arrangement and arc hollow, they have specific application lo applications associated with handling water and other lluid environments.
