Figure 1 shows a perspective view of an embodiment of a module in the form of a wall module generally indicated by the numeral 10. The wall module 10 is for incorporation into an example of a construction in the form of a wall 12 shown in figures 2 and 3, the wall comprising a plurality of wall modules 10, 14, 16 that are in this example substantially similar or identical in form and/or function. Figure 2 shows a perspective view of the wall module 10 ready for incorporation into the wall 12, and figure 3 shows the wall module 10 incorporated into the wall 12.

While the embodiment of figure 1 shows a plurality of wall modules incorporated into a wall, it will be appreciated that the wall construction may an alternative construction, for example the construction may be any one of, for example, a roof, ceiling, and floor. The plurality of modules may be at least one of a plurality of wall modules, a plurality of roof modules, a plurality of ceiling modules and a plurality of floor modules, for example.

The wall module 10 comprises a panel 18 and a periphery in the form of a peripheral frame 20. The peripheral frame, is attached to the panel. In this but not necessarily all embodiments, the peripheral frame circumnavigates the panel, however a topmost frame section is not illustrated in Figure 1 to reveal the interior 54 of the panel 10. In this but not necessarily all embodiments, the peripheral frame 20 is configured for load bearing and has stiffening elements in the form of longitudinal ribs, flanges or wings. The peripheral frame 20 stiffens the wall module 10. Panels 14 and 16 are similarly configured. The peripheral frame 20 is configured to engage and interlock with another peripheral frame 22 of another one 14 of the plurality of wall modules. The periphery of each of the plurality of modules interlock with the periphery of at least one adjacent module of the plurality of modules. The wall modules 10, 14, 16 are substantially the same, with possible differences in their height, however in other embodiments they may be substantially different. In the figures, similar parts are similarly numbered. Figure 4 shows a lateral section of the peripheral frames 20, 22 of engaged wall modules 10, 14, with the respective panels not shown. The peripheral frame 20 and the other peripheral frame 22 are configured to interlock when engaged, by the fitting of at least one projection to at least one recess, preventing relative lateral movement. The peripheral frame 22 comprises a weather seal 23 configured to extend between the peripheral frame 22 and that of a module engaged thereto.

In this but not necessarily in all embodiments, the wall module 10 and panel 18 of figure 1 are rectangular and specifically square, however wall modules and panels may be generally any suitable shape, for example triangular. The wall module 18 has a plurality of peripheral edges 26. Each edge 26 of the wall module 18 has thereat a section of the peripheral frame 20.

Adjacent sections of the peripheral frame are mitred or otherwise joined. The panel 18 extends between opposite ones of the plurality of peripheral frame sections. The sections of the peripheral frame 20 have engaging surfaces identical or substantially identical laterally asymmetric cross sections. In this embodiment, the engaging surfaces are the edges 26 of the wall module. The orientation of each section of the peripheral frame would be that of the section of the peripheral frame opposite rotated 180 degrees around a long axis 19. Consequently, a single extrusion may be cut and used for any on the sections of the peripheral frame 20, which reduces tooling requirements, simplifies design, and reduces the chance of fabrication errors. The extrusion may be, for example, extruded aluminium, extruded polymer, or generally any suitable extruded material. The peripheral frame sections may be formed by techniques other than extrusion, for example by a moulding technique, or milled.

As shown in figures 5 and 6 (the panel 18 being hidden in these figures) the wall module 10 has a lock in the form of a cam lock 28 operationally coupled to the peripheral frame 20 - in this embodiment fastened to the peripheral frame using an adhesive, or alternatively rivets, screws, or any other suitable mechanical fastener - for engaging the other one 14 of the plurality of wall modules, specifically engaging the peripheral frame 22 thereof. The other modules 14, 16 also have cam locks for locking the plurality of modules together. The cam lock 28 in this but not all embodiments has a panel-engaging anchor 30 that is embedded within the panel 18. While in this embodiment a cam lock is used, generally any suitable lock or latch, for example a cross bar or spring latch, may be used. The cam lock has an actuator 32. In this embodiment, the actuator 32 is configured to engage a tool in the form of an Allan (hex) or other key 33, screw or other driver, or generally any suitable tool. An aperture 25 is formed in an outer sheet 52 of the panel through which the tool engages the actuator. In alternative embodiments, the actuator may be in the form of a knob, handle, lever or generally any suitable hand operable feature. The cam lock 28 has a pivot 21 and a latch 36 in the form of a latching tongue rotatable around the pivot by operation of the actuator. The latch may be withdrawn into a cavity within peripheral frame 20 and/or the wall module 10 or rotated out of the cavity and into engagement with the other wall module. When so engaged, lock 28 locks the wall module 10 and the other wall module 14 together. In this embodiment, the latching tongue 36 rotates through a slot formed in the other peripheral frame 22 into a locking position that is, in this but not necessarily in all embodiments, behind the other peripheral frame 22.

The peripheral frame 20 is also configured to engage a rail 24 fixable to a structure, for example a structure comprising at least one of a floor, a ceiling, and a wall. The engagement is in this but not necessarily all embodiments interlocking. The structure in the example of figures 2 and 3 is a wall. A module engaging surface of the rail has the same or substantially the same

configuration as outer surfaces of the peripheral frame. Figure 7 show a perspective view of examples of a wall rail 38 fixed to a wall intersecting with a floor rail 40 fixed to a floor and mitred to the wall rail. The other wall module 14 is being located at the intersection for locking to the wall 38 and floor 40 rails. Figure 8 shows a perspective view of the other wall module 14 being locked to the wall 38 and floor 40 rails by operation of latch mechanisms 28. Figure 9 shows a perspective view of yet another wall module 16 being positioned for engagement with the floor rail 40 and the other wall module 14. Figure 10 shows a perspective view of the peripheral frame 22 of the other panel 14 and the peripheral frame 42 of the yet other wall module 16 in the position of figure 9 with the latch 36 extended as it would be when the other panel 14 and the yet other panel 16 are locked together. Figure 10 shows the latching mechanisms 28 of the yet other wall module 16 being operated such that a latch 36 thereof engages the other module 14. As shown in figures 12 to 14, the module 10 has latching system 43 comprising a latching member in the form of a slidable bolt 44 (which may be generally be in the form of a bar having a transverse section of round, rectangular or generally any suitable shape) extendable beyond the peripheral frame 22. The bolt 44 may be formed of a steel, for example a high tensile steel, a glass reinforced polymer, or generally any suitable material. An interference member comprising an actuator in the form of a lever 46 that extends laterally from the bolt 44. A slot 48 formed in the peripheral frame 22 constrains movement of the bolt around and along the bolt's axis. In a disengaged configuration shown in figure 12, the bolt is withdrawn and disengaged and the interfering member 46 extends between opposite surfaces of the peripheral frame defining the slot and beyond the peripheral frame to prevent engagement with even still yet another one of the plurality of wall modules. In a second configuration shown in figures 13 and 14, the latch system is engaged (the bolt being extended) and the interfering member 46 is withdrawn. The joint 23 between modules 10 and 12 is strengthened by the latching member 44. The guide is configured such that withdrawal of the interference member 46 is blocked unless the bolt is fully extended. Only when the interfering member is withdrawn can the even still yet another one of the plurality of wall modules be engaged. The wall is stiffened by the bolt when extended, and consequently the bolt may be described as a wall stiffening or joint strengthening bolt. This may reduce the possibility of an operator not extending a bolt in the wall structure which may pose a risk of the structure partially or fully collapsing, which may be a significant safety concern. The plurality of modules has a plurality of latching systems that stiffen a plurality of joints.

In alternative embodiments, the bolt 44 may be replaced by a rotatable latch and interference member that has the same safety function.

Figures 15 and 16 show a wall module 74 being engaged with a rail in the form of a top finishing rail 70. The wall module 74 and the finishing rail 70 may be fastened with a mechanical fastener 72 as shown in figure 16. The top finishing rail is, in this embodiment, in the form of an elongated tray or gutter that receives therein the wall module 74. In alternative embodiments, the rail may have a surface configuration of that of the peripheral frame 20, or may generally have any suitable configuration.

In the present but not necessarily in all embodiments, the panel 18 comprises outer sheets 50, 52 that face each other. The outer sheets may comprise any of, for example, orientated strand board, plywood, steel, wall board, gyproc, glass reinforced plastic, paper, and a polymer. The outer sheets are generally but not necessarily cosmetically finished. A core material 54 is disposed between the outer sheets and, in this but not necessarily in all embodiments, is bonded thereto. The core material 54 is a thermally insulating core material in the form of a foam, although any suitable core material may be used. The foam may be, for example, polystyrene foam, a polyisocyanurate foam, and a polyurethane foam.

Figures 18 and 19 show a transverse section of the peripheral frame 80 in various lateral adjustment positions. The peripheral frame 80 comprises a plurality of longitudinal slots 82, 84 having received therein a plurality of outer sheet supports 86, 88. The plurality of slots 82, 84 and the plurality of outer sheet supports 86, 88 have interlocked longitudinal grooves 90, 92 (the grooves being indicated in figure 20) for relative lateral adjustment. Figure 17 and 20 show the peripheral frame with the outer sheet supports 86, 88 separated therefrom. Figure 21 shows a section through locked wall modules 1 10, 1 12 of another embodiment. At least one of the sections of the peripheral frame comprises laterally spaced apart couplings 56, 58 and module outer sheet supports 60 configured to be coupled to any one of the laterally spaced apart couplings 56, 58. Each of the laterally spaced apart couplings 56, 58 are in the form of open ended clamps - in this embodiment C-clamps - configured to slidingly receive a bead at an edge of the module outer sheet supports.

Figures 22 show an embodiment of a wall module 100 having a track 102 facing outward from a major face 103 of the wall module (not a minor face, which is at the outer edge). The track 102 is configured to engage the frame of another wall module 104. Figure 23 shows the other wall module 104 to be engaged to the track 102. The track 102 has generally the same form as the peripheral frame 20. As shown in figure 24 which shows another embodiment, the track 102 may be located at adjacent the periphery of the major face to form a corner module .

Any of the embodiments described above, for example, may optionally have a thermal break 62 configured to impede the flow of heat from one of the outer sheets the other of the outer sheets via the peripheral frame. The thermal break may comprise a polyamide strip, for example. The wall module embodiment of figure 21 has at least one of a ceramic fire-stop and / or weather seal 64.

An example of a method of constructing a wall 12 will now be described In a step of the method, a plurality of wall modules 10, 14, 16 is provided. Each of the plurality of wall modules 10, 14, 16 comprise a panel and a periphery. In another step, the periphery of each of the plurality of modules is interlocked with the periphery of at least one adjacent module of the plurality of modules.

Figure 25 shows show a perspective view of another embodiment of a module in the form of a wall module 210. The module 210 is for incorporation into another example of a wall 212 .having a plurality of wall modules 214, 216, 218 of yet another embodiment that are in this embodiment substantially similar or identical in form and/or function. While the embodiment of figure 25 shows a plurality of wall modules incorporated into a wall, it will be appreciated that the wall construction may be an alternative construction, for example the construction may be at any one of a rood, a ceiling and a floor. The plurality of modules may be at least one of a plurality of wall modules, a plurality of roof modules, a plurality of ceiling modules and a plurality of floor modules.

The wall module 210 comprises a panel 218. Unlike the embodiment of figure 1, however, the panel 218 is not attached to a peripheral frame. Variations on the embodiment of figure 25 may, however, have a peripheral frame. The wall module, however, has a periphery 220 that is configured to engage another periphery 222 of another one of the plurality of wall modules 214. The periphery 220 and the other periphery 222 are configured to interlock when engaged, by the fitting of at least one longitudinal projection in the form of a tongue to at least one longitudinal recess in the form of a groove, preventing relative lateral movement. The longitudinal projection and the longitudinal groove are both central in this but not all embodiments.

A groove receives a tongue to form a joint in the form of a tongue in groove joint. Alternatively, any suitable type of joint may be used. Figure 26 shows a detail from figure 25, which shows the tongue 225 of panel 210 ready to be received by a groove 223 of panel adjacent 214. In this but not necessarily in all embodiment, the wall module 210 and panel 218 are rectangular (others are square), however wall modules and panels may be generally any suitable shape, for example triangular.

The periphery of each of the plurality of modules has a plurality of peripheral sections. Two adjacent peripheral sections of the plurality of peripheral sections each comprise a longitudinal projection, and another two adjacent peripheral sections of the plurality of peripheral sections each have a longitudinal recess.

The periphery 220 is also configured to engage a rail 224 fixable to a structure, for example a structure comprising at least one of a floor, a ceiling, and a wall. A module engaging surface of the rail has the same or substantially the same configuration as outer surfaces of the peripheral frame. Figure 31 shows the mounting rail 224 in detail. The mounting rail has a longitudinal projection in the form of a tongue 225. The wall module 210 has a centrally located recess 227 for receiving the longitudinal projection of the mounting rail.

Figure 27 a wall rail 238 intersects with a floor rail 240 mitred thereto. Figure 28 shows a corner joining angle 241 for joining the floor rail 240 and the orthogonal wall rail 238. The angle 241 is fastened to the wall rail 238 and the floor rail with at least one fastener. The at least one fastener may comprise, for example, a mechanical faster in the form of screws or rivets, or adhesive, or generally any suitable fastener. Figure 29 shows a pin in the form of a hooking pin 243 inserted through opposite apertures formed in the rail 240. The pin is bent, removable and laterally orientated. The hooking pin 243 is engaged by the tongue of a cam lock at an edge of the panel 210 (and an edge of the plurality of pannels), the cam lock being similar or identical to cam lock 245 revealed by removal of a portion module 218.

Figure 30 shows a lateral section of any one of the mounting rails 224, 238 and 240.
