DETAILED DESCRIPTION

[0092] With reference to FIGS. 1 to 6, there is shown a dowel 10 for controlling relative level between adjacent concrete panels, such that one concrete panel of a pathway or the like will stay level with a neighbouring concrete panel to maintain a level path and to avoid a tripping or other hazard. In various embodiments, the dowel 10 is formed of corrosion-free material to avoid corrosion of the dowel 10.

[0093] The adjacent panels being kept level by the dowel 10 are formed of concrete, however it is possible that the dowel 10 and associated formwork system may be used for maintaining a level between panels cast from a different material. As shown in FIGS. 1 to 6, the dowel 10 is formed from material that is non-metallic and is preferably formed of a polymer material or other plastic material that is not prone to corrosion as are typical metal dowels. In one form, the dowel 10 may be formed of a metal material portion covered in a polymer material portion. In that case, the polymer material portion seals within itself the metal material portion in an air-tight seal to protect the metal material portion from corrosion from oxidation.

[0094] FIGS. 3a to 3c show top and perspective views of alternative dowels 10 having a different shape. Whereas the dowel 10 shown in FIGS. 1 to 3 is in the form of a six-sided shape (being rectangular at one side of the flange 18 and having a tapered portion at the other side of the flange), the dowels 10 shown in FIGS. 3a to 3c are four-sided. More specifically, the four-sided dowels 10 of FIGS. 3a to 3c have front and rear sides that are mutually parallel, as well as left and right sides that taper at the same angle on both sides of the flange 18.

[0095] As can be seen in FIGS. 4 and 5, the dowel 10 is substantially planar and is generally in the form of a plate. Opposed edges 12 of the dowel 10 are tapered inwardly toward a central axis of the dowel 10, the central axis lying within a plane of the dowel 10, the central axis lying along the central vertical rib shown in the orientation of FIG. 5. Tapering of the opposed edges 12 of the plate dowel 10 is configured to allow, in situ, lateral movement between the adjacent concrete panels when the concrete panels contract during drying of the concrete. The dowel 10 may have a cross-ribbed structure on an upper surface and on a lower surface to increase structural rigidity.

[0096] As shown in FIG. 5, the dowel 10 may have rounded corners 14 that may be radiused. The dowel 10 may also have rounded edges 16 (see FIG. 4) that may be radiused.

[0097] The dowel 10 may have a flange 18 arranged to abut against a sideform 20 (as seen in FIG. 6) through which the dowel 10 is inserted. The flange 18 extends in a plane perpendicular to the plane of the plate dowel 10. The flange 18 is adapted to seal against the sideform 20 to prevent ingress of concrete to a joint between adjacent concrete panels.

[0098] The dowel may be adapted for use in a non-industrial application and may be adapted for being cast into a concrete pathway to transfer load between adjacent concrete panels of the pathway.

[0099] Accordingly, there is disclosed a corrosion-free tapered plate dowel load transfer system. The tapered plate dowel provides lateral movement once the joint contracts. The double-sided cross-ribbed structure provides increased structural rigidity (providing increased bending strength) by breaking up un-reinforced horizontal surfaces. Corners and edges are radiused to prevent point loads giving even distributed forces at the dowel perimeter. The flange 18 on the dowel 0 acts as a seal preventing concrete ingress into the joint. The flange 18 may optionally incorporate a rubber seal (not shown) to facilitate the sealing effect.

[0100] With reference to FIG. 6, there is shown a concrete pathway formwork system 22 including a sideform 20 for forming adjacent concrete panels of a pathway and a dowel 10 adapted to extend through the sideform 20 for transferring load between the adjacent concrete panels, wherein the dowel is formed of corrosion-free material. The sideform 20 is formed as a unitary panel having one or more ribs 24 between opposed faces 26 to facilitate crushing of the sideform 20 in response to expansion of the concrete panels.

[0101] With reference to FIGS. 7 and 8, there is shown a sleeve 28 for a dowel 10, wherein the sleeve 28 is adapted to clip on to formwork 20 through which the dowel 10 is inserted. With reference to FIG. 7, the sleeve 28 includes a flange 30 for abutting against the formwork 20, a sleeve portion 32 extending from the flange 30, an upper rib 34 supporting the sleeve portion 32 relative to the flange 30 and a lower rib 36 supporting the sleeve portion 32 relative to the flange 30. The flange 30 includes an upper flange portion 38 for engagement with an upper rail 40 of the formwork 20 and a lower flange portion 42 having resilient clips 44 for clipping behind a lower rail 46 of the formwork 20.

[0102] The sleeve 28 may include surrounds around the resilient clips 44 preventing dislodgement of the upper flange portion 38 from the upper rail 40 of the formwork 20. The sleeve 28 may include crushable internal lateral movement voids 48 located at opposed sides of a cavity 50 for receiving the dowel 10. The sleeve 28 may include an expansion void and the sleeve portion 32 may include internal ribs 52 that provide interference on insertion of the dowel 10. The sleeve 28 includes centering ribs 54 which, when the sleeve 28 is clipped on to the formwork 20, protrude into a dowel slot defined by the formwork 20 to prevent lateral misalignment of the sleeve 28 from the slot.

[0103] Accordingly, there is shown a concrete pathway formwork system 22 including a sideform 20 for forming adjacent concrete panels of a pathway, a dowel 10 adapted to extend through the sideform 20 for transferring loads between the adjacent concrete panels, and a sleeve 28 for receiving the dowel 10, wherein the sleeve 28 is adapted to clip on to the sideform 20.

[0104] It should be appreciated that various such embodiments of the present disclosure provide one or more of the following features or advantages: (1) a fastener-less pivoting clip on function for extruded formwork (2) resisting sleeve pull down by bracing itself above sleeve body with locked in cantilevered ribs; (3) ribs below the sleeve brace sleeve in compression; (4) surrounds around the clips that prevent sleeve dislodgement from top pivoting point; (4) incorporating 5 mm crushable internal lateral movement voids and a 10 mm expansion void; (6) corners and edges radiused to prevent point loads giving even distributed forces at the sleeve perimeter; (7) internal ribs providing interference to the plate dowel upon insertion to prevent accidental pull-out during concrete pouring; and (8) centring ribs protruding into the slot on formwork preventing lateral misalignment of the sleeve with the slot.

[0105] With reference to FIGS. 9 to 12, there is also disclosed an articulating dowel system 56, including a dowel 58 and a dowel sleeve 60, wherein the dowel 58 includes a cam portion 62 located within the sleeve 60 to allow the dowel 58 to pivot relative to the dowel sleeve 60.

[0106] The cam portion 62 has a forward rounded part 64 (as seen in FIG. 12) to facilitate pivoting of the dowel 58 relative to the dowel sleeve 60, and a rearward tapered part 66 extending rearwardly and tapering inwardly from the rounded part 64 to limit pivotal movement of the dowel 58 relative to the dowel sleeve 60. The rounded part 64 and the tapered part 66 define a pivot with upper and lower stops to allow limited upward and downward pivoting of the dowel 58 relative to the dowel sleeve 60. The dowel 58 may be formed from corrosion-free material such as, for example, polymer material. The sleeve 60 may be adapted to clip on to a sideform 20 for forming adjacent concrete panels 68. Accordingly, there is shown a concrete paythway formwork system including a sideform 20 for forming adjacent concrete panels 68 of a pathway, a dowel 58 adapted to extend through the sideform 20 for transferring load between the adjacent concrete panels 68, and a sleeve 60 for receiving the dowel 58, wherein the dowel 58 is arranged to pivot upwardly and/or downwardly relative to the sleeve 60. With reference to FIG. 10, the concrete pathway formwork system may include a seal 70 fitted to the sideform 20, the seal 70 having an aperture 72 through which a tongue 74 of the dowel 58 is inserted such that the seal 70 operates to seal between the dowel 58 and the sideform 20 against concrete ingress.

[0107] It should be appreciated that various embodiments of the present disclosure provide one or more of the following features or advantages: (1)corrosion-free articulating dowel system that allows for deflection control on light duty concrete pavements when joint articulates due to tree roots or reactive soil; (2) allowing up to 50 mm of simultaneous vertical lift on slabs while maintaining deflection control, load transfer, lateral dowel movement and expansion capabilities; (3) CAM component of dowel allowing dowel rotation while carrying load horizontally across joint; (4) a fastener-less pivoting clip on function of system to extruded formwork; (5) resisting sleeve pull down by bracing itself above sleeve body with locked in cantilevered ribs; (6) ribs below the sleeve brace sleeve in compression; (7) surrounds around the clips prevent sleeve dislodgement from top pivoting point; (8) incorporating 5 mm crushable internal lateral movement voids and a 10mm expansion void; (9) centring ribs protruding into the slot on formwork preventing lateral misalignment of the sleeve with the slot; (10) dowel is kept horizontal during concrete pour by crushable positioning ribs located internally in the sleeve; and (11) system is sealed off from concrete ingress with an additional seal.

[0108] With reference to FIGS. 13 to 17, there is shown a formwork panel 76 for forming adjacent concrete bodies, wherein the formwork panel 76 is adapted to be compressible on expansion of the concrete bodies. The concrete bodies may be in the form of adjacent concrete panels of a pathway or the like.

[0109] The formwork panel 76 may be substantially planar to be in a plane substantially perpendicular to a travel surface formed by upper surfaces of the concrete bodies. For example, as shown in FIG. 14, the concrete bodies 68 have upper surfaces 78 and the formwork panel 76 is substantially perpendicular to a travel surface (e.g., pathway) formed by the upper surfaces 78. The planar nature of the formwork panel 76 is in contrast to existing formwork that has a cross-sectional shape in the form of an inverted T.

[0110] The formwork panel 76 may be extruded with a constant cross-sectional shape along its length such that the formwork panel 76 is able to be cut to length to suit a particular application. The formwork panel 76 has at least one internal void 80 to facilitate sacrificial compression of the formwork panel 76 on expansion of the concrete bodies 68. The formwork panel 76 has a pair of opposed sideform walls 82 connected by at least one sacrificial rib 84 defining an internal void 80 between the opposed sideform walls 82. The formwork panel 76 has a pair of opposed rails 86 along at least one side of the formwork panel 76, the opposed rails 86 defining a channel for slidable mounting of an accessory to the formwork panel 76. The channel enables the formwork panel 76 to be connected to another like formwork panel 76 (such as seen in FIG. 17) by inserting one end of a joiner plate 88 in the channel of the formwork panel 76 and an opposite end of the joiner plate in the channel of the like formwork panel 76.

[0111] It should be appreciated that various embodiments of the present disclosure provide one or more of the following features or advantages: (1) compressible extruded sacrificial formwork panel and capping; (2) crushable up to 10mm to allow for thermal expansion at joint; (3) multi-functional utility channel that allows for components to be attached continuously along the length; (4) retaining function as an expansion joint and functionally of components when cut; and (5) panels can be joined with joiner plate at any point when cut.

[0112] The formwork panel 76 may also have an upper capping 90, the capping 90 having side walls 92 and a top surface 94 arranged to be level with the upper surfaces 78 of the concrete bodies 68, as shown in FIG. 18. The capping 90 may be adhered to a top of the formwork panel 76 as shown in FIGS. 18 to 21, or may be resiliently clipped or slid on to a top portion of the formwork panel 76 as shown in FIGS. 16 and 17.

[0113] With reference to FIGS. 18 to 21, there is shown a formwork panel 76 for forming adjacent concrete bodies 68, the formwork panel having a formwork panel body 96 and a formwork panel capping 90 arranged to be selectively moved from a coupled condition (as seen in FIG. 18) in which the formwork panel capping 90 is coupled to the formwork panel body 96 to form a surface level with upper surfaces 78 of the concrete bodies 68 and a decoupled condition (as seen in FIG. 19) in which at least part of the formwork panel capping 90 is decoupled from the formwork panel body 96 so as to form a well 98 between the concrete bodies 68. The well 98 may have a predetermined depth being the height of the capping 90, less a thickness of a floor of the capping 90.

[0114] The formwork capping 90 may be formed with a frangible part 100 which is torn to move the formwork panel capping 90 from the coupled condition to the decoupled condition. The frangible part 100 may be located between an upper portion of the capping 90 and a lower portion of the capping 90 such that tearing the frangible part 100 separates the upper portion of the capping 90 from the lower portion of the capping 90. FIG. 18 shows the upper portion and lower portion of the capping 90 connected whereas FIG. 19 shows the upper portion removed from the lower portion. The capping 90 may include opposed arms 102 extending laterally outwardly from opposite sides of the capping 90 such that distal ends of the arms 102 are embedded in the concrete bodies 68. Each of the distal arms 102 may have an enlarged portion 104 to facilitate retainment in the concrete.

[0115] The opposed arms 102 may extend outwardly from the lower portion of the capping 90, and the arms 102 may be able to be stretched to accommodate relative outward movement/retraction of the concrete bodies (as seen in FIG. 21). Advantageously, by virtue of the opposed arms 102 being able to stretch in this way, they stretch with joint opening covering the gap preventing epoxies from running down the joint gap and acting as a debris and weed deterrent.

[0116] It should be appreciated that various embodiments of the present disclosure provide one or more of the following features or advantages: (1) flexible permanent/removable capping; (2) a first option for the capping to remain permanently with joint; (3) a second option for the capping to be ripped off joint (once poured) at tear points to allow scrabbling of joint and to create a welled rebate for use of joint sealants; (4) wings on side anchor into concrete (either side); and (5) ribs stretch with joint opening covering the gap preventing epoxies from running down joint gap and act as a debris and weed deterrent.

[0117] Turning to FIGS. 22 to 28, there is shown a concrete pathway formwork system 22, including a formwork panel 76 for forming adjacent concrete panels of a pathway, and a support bracket 106 for supporting the system 22 relative to a ground surface. The formwork panel 76 has a pair of vertically opposed longitudinal rails 86, and the support bracket 106 has an engagement formation 108 which has an unlocked orientation (as seen in FIG. 23) for inserting the formation 108 between the opposed rails to abut against the formwork panel 76 and a rotated, locked orientation (as seen in FIG. 24) wherein the formation 108 is locked by the rails 86 against lateral withdrawal from the formwork panel 76.

[0118] The formation 108 is unlocked from the opposed rails 86 by rotation of the formation 108 about a lateral axis of the system from the locked orientation to the unlocked orientation.

[0119] The bracket 106 is supported relative to the ground surface by a stake 110 and the bracket 106 has an aperture 112 (as seen in FIG. 28) for receiving the stake. The stake is threaded (see FIG. 22) and has opposed faces 114, the bracket 106 being formed with rotationally spaced engagement portions such that the stake 110 is able to be freely slid along its longitudinal axis through the bracket 106 and locked by rotating the stake 110 about its longitudinal axis relative to the bracket 106.

[0120] As can be seen in FIG. 28, the bracket 106 terminates at a lower end thereof above a lower edge of the formwork panel 76. The formwork panel 76 is formed as a unitary part and has a pair of opposed side walls 82 formed integrally with at least one rib 84, the opposed side walls 82 defining a void 80 therebetween. In the example shown in FIG. 27, the formwork panel 76 has six such ribs 84, comprising two external ribs and four internal ribs. The bracket 106 may itself be formed as a unitary part and may have a central rib 116 extending along the length of the bracket 106.

[0121] FIGS. 29a to 29d show a clip-on foot 120 for supporting the formwork panel 76. In particular, there is provided a clip-on foot 120 having a portion 122a and 122b for clipping on to a bottom tapered rail of the formwork panel 76. The portion for clipping on to the bottom tapered rail is formed of long upright support 122a and a short upright support 122b. The long upright support 122a has a strengthening brace 124 extending from the long upright support 122a downwardly and outwardly to be supported along a horizontal foot portion of the clip-on foot 120. The horizontal foot portion also has a pair of opposed notches 126 for soil nailing of the formwork profile using pins. Advantageously, the clip-on foot 120 enables the formwork profile to be freestanding, with multiple (for example three or four) clip-on feet to be fitted along a span of the formwork. The clip-on foot 120 enables the formwork to be moved to a final position, with the notches 126 being used for pinning the formwork panel 76 in position directly in the soil.
