DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[00025] According to an embodiment of the present invention, there is provided a modular wall system 100 as shown in Figure 1. The system 100 includes many modules including block wall modules 102 for forming a pair of walls 104a, 104b, and horizontal and vertical spacers for spacing the walls 104a, 104b apart as explained in detail below.

[00026] Advantageously, the system 100 is provided in kit form as a do-it-yourself system 100 so that users without landscaping skills can readily assemble the system 100. The system 100 further includes concrete, foam or other fillers poured between the walls 104a, 104b as they are sequentially built.

[00027] Turning to Figure 2, the wall modules 102 include module interlocking means to vertically interlock adjacent wall modules 102 together. In particular, the interlocking means includes top tongues 200 for being receiving in respective underside grooves (not shown). The tongues 200 snugly fit vertically and axially in respective underside grooves. The perimeter of the wall modules 102 define elongate cladding grooves 202 for receiving tongues of cladding parts as explained below.

[00028] The system 100 includes vertical (i.e. first) spacers 204. Spacer interlocking means is provided for interlocking the wall modules 102 with the spacers 204. The spacer interlocking means includes a tongue and groove arrangement. Each spacer 204 includes a panel 206, and a pair of bulbous tongues 208 terminating either side of the panel 206. The panel 206 includes an aperture 210 through which rebar reinforcement may pass. The bulbous tongues 208 of the tongue and groove arrangement slide vertically and transversely into respective complementary grooves 212 in the modules 102.

[00029] Turning to Figure 3, the system 100 also includes horizontal (i.e. second) spacers 300 that rest on the vertical spacers 204. Each horizontal spacer 300 includes a panel 302, and tongues 304 on either side of the panel 302. The tongues 304 have a bulbous head terminating a neck. The bulbous tongues 304 of the tongue and groove arrangement slide vertically and transversely into respective complementary grooves 212 in the modules 102, as before.

[00030] Each horizontal spacer 300 also includes another spacer interlocking means for interlocking like adjacent spacers 300. This spacer interlocking means includes a dove-tail tongue and groove arrangement, with tongue 306 and opposing complementary groove 308.

[00031] Turning to Figure 4, the system 100 further includes capping 400 for capping the uppermost modules 102 of the walls 104, once all the modules 102 are laid. Similar to before, the system 100 includes capping interlocking means for interlocking the capping 400 with the walls 104. The capping interlocking means includes a tongue and groove arrangement. In particular, the tongue and groove arrangement includes the module tongues 200 for sliding axially into respective grooves (not shown) on the underside of the capping 400.

[00032] The perimeter of the capping 400 defines elongate cladding grooves 202 for receiving tongues of cladding for cladding the walls 104, as before. The cladding includes top cladding 402 shown in Figure 4, end cladding 500 as shown in Figure 5, and side cladding 600 as shown in Figure 6.

[00033] The system 100 further includes cladding interlocking means for interlocking the cladding with the walls. The cladding interlocking means includes a tongue and groove arrangement. The tongue and groove arrangement includes cladding tongues 404 for being received in respective cladding grooves 202.

[00034] The wall modules 102, spacers 204, 300, capping 400 and cladding 402, 500, 600 are integrally formed, resilient and preferably injection molded from polymeric material. The wall modules 102 may be straight, or curved to form corners or curved walls.

[00035] As shown in Figure 7, an end tongue 200 of one of the wall modules 102 can be received in an end groove of another one of the wall modules 102 so that the wall modules 102 can be oriented so as to be misaligned in forming corners or angled walls.

[00036] A method for assembling the modular wall system 100 is now described. [00037] Initially, the method involves spacing a pair of wall modules 102 apart using an interconnected vertical spacer 204 (Fig. 2). A base row of the walls 104a, 104b is then similarly formed (Fig.1 ). Concrete can be poured between the modules 102.

[00038] Next, the horizontal spacers 300 are interconnected with the wall modules102, rested on the vertical spacers 204 and interconnected together to form a shelf extending along the base row of the walls 104a, 104b (Fig. 3).

[00039] Next, the side cladding 600 is interlocked with the wall modules102 (Fig. 6), and the end cladding 500 received by the end of the base row of the walls 104a, 104b (Fig. 5).

[00040] Next, additional rows of the walls 104a, 104b are formed to a desired height (Fig. 1) in the same manner.

[00041] Next, the capping 400 is interlocked with the top row of the walls 104a, 104b (Fig. 4).

[00042] Finally, the top cladding 402 is interlocked with the capping 400, or in some embodiments with the wall modules 102 directly.

[00043] A person skilled in the art will appreciate that many embodiments and variations can be made without departing from the ambit of the present invention.

[00044] The system 100 of the preferred embodiment was used to form a retaining wall. In other embodiment, the system 100 may be used in building construction.

[00045] In one embodiment, the vertical spacers 204 have a solid panel 206, with no aperture 210, to “close off” vertical sections of the wall system 100. These sections can then be filled with concrete (or other fillers) to create structural columns to create or allow for post and beam construction, as opposed to solid reinforced wall construction.

[00046] In compliance with the statute, the invention has been described in language more or less specific to structural or methodical features. It is to be understood that the invention is not limited to specific features shown or described since the means herein described comprises preferred forms of putting the invention into effect. The invention is, therefore, claimed in any of its forms or modifications within the proper scope of the appended claims appropriately interpreted by those skilled in the art.

[00047] Reference throughout this specification to ‘one embodiment’ or ‘an embodiment’ means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, the appearance of the phrases ‘in one embodiment’ or ‘in an embodiment’ in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more combinations.
