Description

Technical Field [0001] Embodiments generally relate to connection systems, components of connection systems, and methods for connecting a wall panel to an anchoring structure such as a floor.
Background [0002] Conventional stud walls are generally constructed on-site in a building structure. However, there are significant costs associated with on-site labour, materials handling, and wastage through off-cuts, as well as the challenges in controlling quality.
[0003] Instead of constructing walls on-site, some builders have started to use prefabricated wall panels which are fabricated off-site in a factory, then transported to the building site, erected, and fastened in place by connecting the wall panels to floors.
[0004] Existing methods for connecting wall panels to floors generally involve using mechanical fasteners and/or brackets to connect part of the wall panel to the floor. Such methods are time consuming and require a certain degree of skill as well as a large range of tools.
[0005] It is desired to address or ameliorate one or more disadvantages or shortcomings of existing connection systems and methods for connecting a wall panel to a floor, or to at least provide a useful alternative thereto.
[0006] Throughout this specification the word comprise, or variations such as comprises or comprising, will be understood to imply the inclusion of a stated element, integer or step, or group of elements, integers or steps, but not the exclusion of any other element, integer or step, or group of elements, integers or steps.

WO 2017/100854
PCT/AU2016/051244 [0049] Referring to Figures 2A to 2C, a number of bases 130 are shown in further detail. The base 130 may comprise a base plate 132 defining one or more fastening apertures 134 each configured to receive a mechanical fastener to fix the base 130 to the floor 102. The base plate 132 may comprise a substantially flat panel or plate which may be formed of solid metal. In some embodiments, the fastening apertures 134 may comprise slotted holes to allow for adjustment of the position or angle of the base 130 after initial installation of the base 130 on the floor 102. That is, instead of being circular, the fastening apertures 134 may be defined by elongate slots in the base plate 132. A major axis of the elongate slots may be generally parallel with a base frame member 112 running along the width of the wall panel 110 when installed. Part of the base frame member 112 may cover at least part of the base plate 132 when the wall panel 110 is connected to the base 130, and the lower surface 104 of the wall panel 110 may include one or more recessed portions (not shown) to ensure that the lower surface 104 is flush with and abuts the floor 102 and the base plate 132. In particular, part of the lower surface 104 surrounding the socket 118 may be in contact with an upper surface 136 of the base plate 132 when the wall panel 110 is connected to the base 130.
[0050] The base 130 may be fixed, fastened, or anchored to any suitable anchoring structure such as a floor, for example. Any appropriate mechanical fasteners such as screws, bolts, nails or rivets, for example, may be used to fasten the base plate 132 to any floor such as timber, cement, concrete or tiles, or to another anchoring structure such as a screw pile or other foundation structure.

In some embodiments, the base connector 140 and locator 146 may be welded to the base plate 132.
[0052] The base plate 132 may have a thickness in the range of about 1mm to 10mm, optionally about 2mm to 7mm, optionally about 3mm to 5mm. The width of the base
WO 2017/100854
PCT/AU2016/051244 plate 132 in a (direction corresponding to the depth of the wall panel 110) may be in the range of about 50mm to 300mm, optionally about 80mm to 200mm, optionally about 100mm to 150mm. In various applications, the width of the base plate 132 may be equal to, greater than, or less than the depth of the wall panel 110. The length of the base plate 132 may be in the range of about 100mm to 1000mm, optionally about 200mm to 500mm, optionally about 300mm to 400mm.
[0053] The base connector 140 may extend away from the base plate 132 in a direction substantially normal to the upper surface 136 of the base plate 132. The base connector 140 may comprise a solid and substantially flat plate 142 with a hooked end or hook portions (referred to herein as hook 144) formed at an end of the base connector 140 distal to the base plate 132. The hook 144 may be configured to engage with a loop or hook of the latch 150 such that when the latch 150 is connected to the hook 144 and tensioned, forces are transferred between the wall panel 110 and the base 130 via the latch 150 and the hook 144. In some embodiments, the base connector 140 may comprise a loop (not shown) configured to engage with a hook of the latch 150, and the connection between them may operate in a similar manner to that described above.
[0054] The base connector 140 may extend away from the base plate 132 by a distance in the range of about 30mm to 300mm, optionally about 50mm to 250mm, optionally about 100mm to 200mm. The thickness of the flat plate 142 may be in the range of about 1mm to 10mm, optionally about 2mm to 7mm, optionally about 3mm to 5mm. The width of the flat plate 142 may be in the range of about 10mm to 100mm, optionally about 20mm to 70mm, optionally about 30mm to 50mm. The hook 144 may be an extension of the flat plate 142 with similar width dimensions, but simply bent into a hook shape. The hook 144 may comprise a semi-cylindrical shape with an internal diameter in the range of about 2mm to 10mm, optionally about 3mm to 8mm, optionally about 5mm to 7mm.
[0055] The locator 146 may comprise a protrusion 148 extending away from the base plate 132 on the same side of the base plate 132 as the base connector 140 and spaced
WO 2017/100854
PCT/AU2016/051244 from the base connector 140. In some embodiments, the protrusion 148 may be generally cylindrical. In some embodiments, the protrusion may define a solid or hollow prism, such as a polygonal prism, for example. The length of the locator 146 in a direction extending away from the base plate 132 may be sufficient to provide temporary support to the wall panel 110 during installation before the latch 150 is tensioned, and may assist in maintaining the wall panel 110 in a vertical orientation.
The locator 146 may temporarily support the wall panel 110 against wind loads during installation before the building is sealed or until other supporting structures are put in place. The length of the locator protrusion 148 may be in the range of about 100mm to 500mm, optionally about 146mm to 400mm, optionally about 200mm to 300mm. In some embodiments, the length of the locator protrusion 148 may be significantly greater than the width of the base plate 132, such as by a factor of more than 1.2, 1.5, 2 or 3, for example. The diameter of the locator protrusion 148 (transverse to its length) may be in the range of about 10mm to 100mm, optionally about 20mm to 50mm, optionally about 30mm to 40mm.
[0056] In some embodiments, instead of or as well as a protrusion 148, the locator 146 may comprise a socket or recess (not shown) in the base 130, or one or more walls extending away from the base plate 132 configured to receive part of the wall panel 110 and assist in locating the wall panel 110 relative to the base 130. In some embodiments, instead of a base plate 132, the base 130 may comprise an anchoring pin configured to be fixed or set in the floor 102 and support the base connector 140 and locator 146.
[0057] In some embodiments, the base 130 may comprise a plurality of locators 146 and base connectors 140 configured to allow a respective plurality of wall panels 110 to be connected to the base 130.

In other embodiments, the base 130 may comprise further base connectors 140 and locators 146 to form a four-way cruciform junction, for example, or any other wall junction which may be desirable.
[0060] Referring to Figures 3 A to 3D, part of a wall panel 110 is shown as it connects to a base 130. The wall panel 110 may comprise a socket 118 configured to receive the locating protrusion 148 of the base 130 to assist in positioning the wall panel 110 relative to the base 130. The socket 118 may comprise a recess formed in one of the frame members 112. The socket 118 may define a complementary inner surface adapted to mate with an outer surface of the locating protrusion 148. In some embodiments, the socket 118 and locating protrusion 148 may define complementary keyed surfaces to assist in positioning the wall panel 110 at a desired angle.
[0061] The wall panel 110 may include a socket 118 at or near each end of the lower surface 104 and a wall panel connector 120 disposed on an upright frame member 114 near each socket 118 as shown in Figure 1 A. The two wall panel connectors 110 and two sockets 118 may be configured to engage with respective base connectors 140 and locators 146 of two bases 130 as shown in Figures 1A and IB.
[0062] Referring to Figures 3A to 3D and 4A to 4C, the latch 150 is shown in more detail, according to some embodiments, in the form of an over-centre latch. The latch 150 comprises a mounting bracket 152, which may be in the form of a shear plate, for example. The mounting bracket 152 includes a plurality of fastening apertures 154 configured to receive mechanical fasteners such as nails, screws or bolts, to fasten the latch 150 to the wall panel 110. The mounting bracket 152 may be fastened to a frame member 112 and the latch 150 may be disposed within the frame 114, i.e., in a space between two or more of the frame members 112. The mounting bracket 152 may be fastened to an upright frame member 112 or column which also includes the socket 118.
WO 2017/100854
PCT/AU2016/051244 [0063] The latch 150 may further comprise a lever 156 pivotally connected to the mounting bracket 152 at a first pivot 158, forming a fulcrum between the lever 156 and the mounting bracket 152. The first pivot 158 may be located at or near a first end of the lever 156. The lever 156 may comprise a handle allowing a user to rotate the lever 156 to tension the latch 150.
[0064] As mentioned previously, the latch 150 may comprise a hook or loop configured to engage with the hook 144 of the base connector 140 (or a hook if the base connector comprises a loop). In Figures 3 A to 3D and 4A to 4C, the latch 150 is shown with a loop 160 configured to engage with the hook 144 of the base connector 140 to connect the wall panel connector 120 to the base connector 140. The loop 160 may be pivotally connected to the lever 156 at a second pivot 162 spaced from the first pivot 158. The second pivot 162 may be nearer the first pivot 158 than a second end of the lever 156. A total length of the lever 156 may be significantly greater than a distance between the first and second pivots 158, 162, such as greater than four times the distance, optionally greater than five, six, seven, eight, nine or ten times the distance, for example.
[0065] In some embodiments, the latch 150 may comprise a securing mechanism or lock 164 to secure the lever 156 in position after the latch 150 has been tensioned. The lock 164 may comprise a locking loop 166 extending away from the mounting bracket 152 and configured to pass through a lock aperture 168 in the lever 156 (see Figure 3D) when the lever 156 is rotated to a certain angle relative to the mounting bracket 152 to tension the latch 150. The lever 156 may then be secured at that angle by placing a locking pin (not shown) in the locking loop 166 such that the locking pin extends through the locking loop 166 and across the lock aperture 168 to restrict the lever 156 from being rotated away from the mounting bracket 152 and releasing the latch 150 from the base connector 140.
[0066] Referring to Figures 4A to 4C, a method of closing the latch 150 is shown. In Figure 4A, an upright frame member 112 is shown in place on a base 130 with the locator 146 received in the socket 118. The lever 156 is extending away from the
WO 2017/100854
PCT/AU2016/051244 mounting bracket 152 at an angle and the loop 160 is not engaged with the base connector 140. The loop 160 may then be rotated towards the base connector 140 to contact the base connector 140 as shown in Figure 4B. The lever 156 may then be rotated towards the mounting bracket 152 to tension the loop 160 against the hook 144 of the base connector 140 and force the lower surface 104 of the wall panel 110 against the floor 102 and/or the base plate 132.
[0067] The connection and tensioning sequence described may be performed manually and without any additional tools, since due to the mechanical advantage of the lever 156, the force required to tension the connection is significantly less than the tension applied to the connection. The mechanism of the over-centre latch shown may be described as a rotating over-centre cam or a second class lever with the first pivot 158 providing a fulcrum, the second pivot 162 and loop 160 providing a resistance, and the user’s hand providing an effort on the lever 156 on an opposite side of the second pivot 162 from the first pivot 158.
[0068] There should be some resilience in the connection in order to maintain the tension and force the wall panel 110 against the floor 102 and/or base 130. That is, one or more components of the wall panel connector 120 or base connector 140 should be configured to be put under a certain amount of strain (without breaking or becoming damaged or otherwise experience material failure)_when the connection between them is tensioned. For example, any one or more of: the loop 160, the hook 144, the base connector 140, the lever 156, the mounting bracket 152 or any of the connections between the components may be resilient and configured to be put under strain (without breaking or becoming damaged or otherwise experience material failure) when the connection between the wall panel connector 120 and the base connector 140 is tensioned.
[0069] The latch 150 may be formed of any suitable materials which provide the requisite tensile strength and resilience, such as a polymer, metal, metal alloy, steel, structural steel, or tensile steel, for example. Existing latches such as over-centre latches may be purchased and fitted to the wall panel 110.
WO 2017/100854
PCT/AU2016/051244 [0070] The lever 156 may be formed of plate metal folded or stamped into a Ushaped channel. The length of the lever 156 may be in the range of about 100mm to 300mm, optionally about 150mm to 250mm, optionally about 200mm. The width of the lever 156 may be in the range of about 10mm to 70mm, optionally about 20mm to 60mm, optionally about 40mm to 50mm.
[0071] The loop 160 may be formed of a metal rod bent or otherwise formed into a rounded, rectangular or trapezoidal loop. The diameter of the rod may be in the range of about 2mm to 10mm, optionally about 3mm to 8mm, optionally about 5mm to 7mm. The width of the loop 160 may be in the range of aboutlOmm to 70mm, optionally about 20mm to 60mm, optionally about 40mm to 50mm. The length of the loop may be in the range of about 20mm to 200mm, optionally about 50mm to 150mm, optionally about 80mm to 120mm.
[0072] It will be appreciated by persons skilled in the art that numerous variations and/or modifications may be made to the above-described embodiments, without departing from the broad general scope of the present disclosure. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive.
