The present application claims priority to and the benefit of Australian Patent Application No. 2021204995, filed Jul. 12, 2021, the entire contents of which are incorporated herein by reference.
The present disclosure relates broadly to an edge protection system, or an armoured joint, for protecting the edges of components formed of settable material such as concrete. The components formed of settable material may be in the form of concrete flooring components, for example, flooring components of industrial concrete flooring. The present disclosure relates to a fully bridged wave plate and, more particularly, but not exclusively, to a fully bridged and supported top wave plate.
It is known that the edges of components formed of settable material—such as concrete—may be subject to damage. In particular, where the components formed of settable material are in the form of concrete flooring components forming a floor surface (such as in a warehouse or storage facility), the edges of the concrete flooring components may be subject to damage as forklifts and the like travel from one concrete component onto a neighbouring concrete component. This damage may be exacerbated where one flooring component rises relative to the neighbouring flooring component forming a raised bump which is subject to wear.
It has been proposed to provide an edge protection system to protect the edges of concrete flooring components. However, the applicant has determined that existing edge protection systems are relatively expensive, may be over-engineered, may be subject to incorrect installation and/or may not adequately prevent movement of one concrete panel relative to a neighbouring concrete panel. Examples of the present disclosure aim to improve the life-cycle of a material handling equipment (MHE) crossing by providing an impact free joint, providing an alternative to straight gap systems with wheel impact.
The applicant has determined that it would be advantageous for there to be provided an improved edge protection system which alleviates or at least ameliorates one or more of the disadvantages of existing edge protection systems. In particular, the applicant has identified that it would be advantageous for there to be provided a joint edge management system which provides load transfer, protecting concrete edges from spelling caused by materials handling equipment (MHE) with small hard wheels, travelling at speed, carrying high loads.
There is disclosed a joint edge protection apparatus for protecting an edge of a first component formed of settable material and an edge of a second component formed of settable material at a joint, wherein the apparatus includes a first anchorage part for anchoring within the first component and a second anchorage part for anchoring within the second component, a first plate coupled to the first anchorage part, a second plate coupled to the second anchorage part, the first plate defining a first abutment surface, the second plate defining a second abutment surface, wherein the first abutment surface and the second abutment surface are shaped to facilitate abutment of at least a portion of the second abutment surface against the first abutment surface, and wherein the second anchorage part is adapted to be movable relative to the first anchorage part from an abutting configuration in which at least a portion of the second abutment surface is in abutment with the first abutment surface to a spaced configuration in which the second abutment surface is spaced relative to the first abutment surface, wherein the first anchorage part defines a support surface to support the second plate as the second anchorage part is moved between the abutting configuration and the spaced configuration, and wherein, in the abutting configuration an interface between the first abutment surface and the second abutment surface is offset relative to an interface between the first anchorage part and the second anchorage part such that the interface of the first abutment surface and the second abutment surface is positioned above the support surface.

In an alternative form, the wave shape of the first abutment surface is mismatched to the wave shape of the second abutment surface to facilitate periodic abutment in the abutting configuration.
In a preferred form, the apparatus is arranged such that a gap between the first abutment surface and the second abutment surface, throughout a range of movement, is located above said support surface such that the gap is fully spanned by the support surface. More preferably, the gap is fully bridged by the support surface such that contaminants including vermin and debris are prevented from entering the joint between the first component and the second component. Even more preferably, the fully bridged gap provides a well for application of joint material. In one example, the joint material is in the form of a joint epoxy and/or sealant.
Preferably, the range of movement corresponds to a gap between the first abutment surface and the second abutment surface being between 0 mm and 20 mm.

The apparatus 10 includes a first anchorage part 18 for anchoring within the first component 12 and a second anchorage part 20 for anchoring within the second component 14. The apparatus 10 also includes a first plate 22 coupled to the first anchorage part 18, a second plate 24 coupled to the second anchorage part 20, the first plate 22 defining a first abutment surface 26 and the second plate 24 defining a second abutment surface 28.
The first abutment surface 26 and the second abutment surface 28 are correspondingly shaped to facilitate abutment of the second abutment surface 28 against the first abutment surface 26. The second anchorage part 20 is adapted to be movable relative to the first anchorage part 18 from an abutting configuration (the

In the preferred example shown in the drawings, the apparatus 10 is arranged such that a gap 32 between the first abutment surface 26 and the second abutment surface 28, throughout a range of movement, is located above the support surface 30 such that the gap 32 is fully spanned by the support surface 30. In this way, the gap 32 is fully bridged by the support surface 30 such that debris is prevented from entering the joint 16 between the first component 12 and the second component 14. The fully bridged gap 32 may provide a well 34 for application of joint material 36. The joint material 36 may be in the form of a joint epoxy and/or sealant.
The range of movement corresponds to a gap 32 between the first abutment surface 26 and the second abutment surface 28 being between 0 mm and 20 mm.
In use, the offset results in the interface between the first abutment surface 26 and the second abutment surface 28 being offset from a centre of the joint 16 between the first component 12 and the second component 14.
The first anchorage part 18 may include a first lacer bar 38 supported by a series of spaced ribs 40. Similarly, the second anchorage part 20 may include a second lacer bar 42 supported by a series of spaced ribs 40. Each of the lacer bars 38, 42 may be in the form of a rail.

More specifically, as will be appreciated from the above, the joint edge protection apparatus 10 provides an armoured joint for protecting an edge of the first component 12 formed of settable material and an edge of the second component 14 formed of settable material at the joint 16. The apparatus 10 includes the first anchorage part 18 for anchoring to the first component 12 and the second anchorage part 20 for anchoring to the second component 14. The apparatus 10 also includes the first plate 22 coupled to the first anchorage part 18 and the second plate 24 coupled to the second anchorage part 20. The first plate 22 defines the first abutment surface 26 in the form of a first edge and the second plate 24 defines the second abutment surface 28 in the form of a second edge. The first edge 26 and the second edge 28 are correspondingly shaped to facilitate bringing together of the first edge 26 and the second edge 28. In particular, the second anchorage part 20 is adapted to be movable relative to the first anchorage part 18 from a close configuration (see

The bracket 50 comprises an angled upper leg 54 and an angled lower leg 56, the bracket 50 being fixed to the support section 52 by the angled upper leg 54 and the angled lower leg 56. With reference to
A distal end 62 of the upper leg 54 is fixed relative to a distal end 64 of the lower leg 56. The distal end 62 of the upper leg 54 may be connected to the distal end 64 of the lower leg 56 by way of an intermediate portion as shown in
As shown in
Turning to
The upper leg 54 may meet the lower leg 56 at a bent portion of the bracket 50, as shown in
There may also be provided the armoured joint together with the stake in an assembly. In other words, there may be provided an assembly including an armoured joint as described above, in combination with a stake, wherein the stake extends through the upper leg and the lower leg.
As shown clearly in
The first anchorage part 18 may include the elongated angled anchorage lacer bar 38, the elongated angled anchorage lacer bar 38 being supported by a series of spaced ribs 40 and the lacer bar 38 being tilted out of the plane of the ribs 40.
The first anchorage part 18 may define the support surface 30 to support the second plate 24 as the second anchorage part 20 is moved between the close configuration and the spaced configuration.

Each of the apertures 66, 70 may be in the shape of a slot (see
Accordingly, as will be appreciated from the above, this aspect relates to:
With reference to
More specifically, there is shown an edge protection system 72 including a first expandable armoured joint 74 to protect a first joint 76 extending in a first direction, a second expandable armoured joint 78 to protect a second joint 80 extending in a second direction and an intersection module 82 including a cover plate 84 located at an intersection 86 of the first expandable armoured joint 74 and the second expandable armoured joint 76. The first expandable armoured joint 74 and the second expandable armoured joint 78 may each be in the form of a joint edge protection apparatus 10 as described above.
The first expandable armoured joint 74 includes a first pair of plates 88 arranged to be moved apart to open a crevice 90 between the plates in response to expansion of the first joint 76, and the second expandable armoured joint 78 includes a second pair of plates 92 arranged to be moved apart to open a crevice 94 between the plates 92 in response to expansion of the second joint 80. Each of the first pair of plates 88 has a wavy edge 96, the wavy edges 96 being brought together in a contracted condition of the first expandable armoured joint 74. Each of the second pair of plates 92 also has a wavy edge 96, the wavy edges 96 being brought together in a contracted condition of the second expandable armoured joint 78.
The cover plate 84 is removable from a remainder of the intersection module 82.
The edge protection system 72 includes an anchored support 98 for supporting the intersection module 82 relative to a ground surface. An upper support 100 of the intersection module 82 is adapted to receive the cover plate 84 fastened thereto. The anchored support 98 anchors the intersection module 82 in a fixed location relative to the ground surface during expansion of the first expandable armoured joint 74 and the second expandable armoured joint 78.
In the example shown, the first joint 76 is a joint between concrete slab sections 102 and the second joint 80 is also a joint between concrete slab sections 102. The cover plate 84 is a load supporting member being braced by each slab section 102 when the slab sections 102 move through slab shrinkage. In particular, it is typical for the slab sections 102 to shrink during drying of the concrete. More specifically, the cover plate 84 is a load supporting member being braced by each slab section 102 when the slab sections 102 move through slab shrinkage with each slab moving up to 20 mm. This support may be achieved by way of the intersection module 82 having a separate anchorage part 104 for each of the separate slab sections 102, such that each anchorage part 104 is cast into a respective one of the slab sections 102. In turn, the anchorage parts 104 are vertically supported by a central lower shoulder 106 and a central upper shoulder 108 of the intersection module 82.
The intersection module 82 includes a central support column 110, the central support column 110 having an upper support plate (in the form of central upper shoulder 108) and a lower anchor plate (in the form of central lower shoulder 106), the cover plate 84 being fastened to the upper support plate 108 so as to be connected to the central support column 110 and the lower anchor plate 106 to remain vertically coupled to the concrete slab sections 102.
The edge protection system 72 includes a stake 112 which is inserted through the central support column 110 for supporting the intersection module 82 relative to the ground surface. The upper support plate (central upper shoulder 108) may be in the form of an upper cleat plate which is spaced vertically from the lower anchor plate (central lower shoulder 106).
The stake 112 may be in the form of a star picket. The stake 112 may be arranged to prevent the central support column 110 from rotating relative to the ground surface and from translational movement relative to the ground surface, as depicted by arrows in
In the example shown in the drawings, the first direction is not parallel to the second direction such that the first joint 76 is not parallel to the second joint 80. More specifically, in the example shown in the drawings, the first direction is perpendicular to the second direction such that the first joint 76 is perpendicular to the second joint 80.
Accordingly, as will be appreciated from the above, this aspect relates to:
With reference to
More specifically, as shown in the drawings, there is depicted an edge protection system 72 including a first expandable armoured joint 74 to protect a first joint 76 extending in a first direction and a second expandable armoured joint 78 to protect a second joint 80 extending in a second direction. The edge protection system 72 also includes an intersection module 82 at an intersection 86 of the first expandable armoured joint 74 and the second expandable armoured joint 78. The first expandable armoured joint 74 has a first joint line 116 and the second expandable armoured joint 78 has a second joint line 118. The intersection module 82 provides a perimeter joint line 120 such that there is a continuous joint line including the first joint line 116, the perimeter joint line 120 and the second joint line 118.
The intersection module 82 includes the cover plate 84, and the continuous joint line extends at least partially around a perimeter of the cover plate 84 between the first joint line 116 and the second joint line 118.
The first joint line 116 has a generally wavy form and the second joint line 118 also has a generally wavy form. The cover plate 84 is arranged such that, regardless of where lengths of the wavy first and second plate pairs 88, 92 are cut, the wavy first joint line 116 and the wavy second joint line 118 will connect to the active joint line of the intersection module 82. In one form, the cover plate 84 is arranged to ensure that joint lines are matched to standard joint runs.
As will be appreciated by those skilled in the art, joint openings at the perimeter of the cover plate 84 are halved in thickness when used in a four-way intersection configuration, as shown in
Accordingly, as will be appreciated from the above, this aspect relates to:
With reference to
In particular, the edge protection system 72 includes a first expandable armoured joint 74 to protect a first joint 76 extending in a first direction and a second expandable armoured joint 78 to protect a second joint 80 extending in a second direction. The edge protection system 72 also includes an intersection module 82 at an intersection 86 of the first expandable armoured joint 74 and the second expandable armoured joint 78. The intersection module 82 has an indicator 122 to enable a user to ensure correct orientation of the intersection module 82.
The intersection module 82 includes a cover plate 84 which is generally symmetrical in shape. In particular, as shown in the drawings, the cover plate 84 is generally octagonal in shape.
The indicator 122 may be in the form of a discreet marking. In one particular form, the indicator 122 may be in the form of a small hole in the cover plate 84. The indicator 122 is provided to enable a user to orientate joints during installation on-site in a common direction to ensure joint lines match.
This is important as although the cover plate 84 itself appears to be symmetrical from above, the components of the intersection module 82 below the cover plate 84 are not symmetrical. Specifically, it is important that the anchorage parts 104 of the intersection module 82 align with the joints of the concrete slab sections 102, as well as with the anchorage parts 104 of the other intersection modules 82 within the edge protection system 72.
In a method of installation, the indicator 122 is positioned in one of four rotational orientations on a first intersection module 82 on-site depending upon a first pour location. Subsequent intersection modules 82 within the same edge protection system 72 (see
The intersection module 82 may be arranged to allow for two-way, three-way and four-way intersections to be formed without adjusting orientation of the intersection module 82.
With reference to
The first expandable armoured joint 74 may have a first joint line 116, and the second expandable armoured joint 78 may have a second joint line 118. The intersection module 82 may provide a perimeter joint line 120 such that there is a continuous joint line including the first joint line 116, the perimeter joint line 120 and the second joint line 118.
Accordingly, as will be appreciated from the above, this aspect relates to:
Advantageously, the applicant has identified that examples of the present disclosure may serve to prolong the serviceability of the floor (working surface). Forklift wheels are fully supported by the “wave” plate design to a joint width opening of 20 mm. Modular design intersection provides a fast, effective and intuitive set up of two, three and four way intersections, significantly mitigating the risk of restraint that leads to uncontrolled concrete cracking and spelling.
In particular,
As can be seen in
As will be appreciated, in each of the configurations shown in
Returning to
As shown in
Accordingly,
The described construction has been advanced merely by way of example and many modifications and variations may be made without departing from the spirit and scope of the present disclosure, which includes every novel feature and combination of features herein disclosed. In particular, the applicant has determined that other modifications may include one or more of the following:
Throughout this specification and the claims which follow, unless the context requires otherwise, the word “comprise”, and variations such as “comprises” and “comprising”, will be understood to imply the inclusion of a stated integer or step or group of integers or steps but not the exclusion of any other integer or step or group of integers or steps.
