<p>The spacer 1 defines a body (2) having two opposed sides (3) and (4). The body (2) defines a separation distance between the opposed sides (3) and (4) for use as a spacer intermediate at least two concrete containment panels (5) and (6). Various preferred embodiments have separation distances suitable for forming walls having concrete thicknesses of 50mm, 120mm or 150mm, for example. Each of the opposed sides (3) and (4) include fastening means (7) and (8) adapted for fastening of a cladding panel (16) disposed external to the concrete containment panels (5) and (6), as shown for example in figures (32) and (33). To counter bulging of the concrete containment panels (5) due to the weight of the concrete a brace (49) adapted for fastening engagement with the spacers (1) may be used, as shown in figures (50) to (55). The brace 49 includes an abutment member (50) for abutment with the concrete containment panels (5). A plurality of fastening means (51) are disposed on the abutment member (50) for fastening engagement with spacers (1). The fastening means (51) each define a leading portion (52) and a trailing portion (53). As shown for example in figure (50), the leading portion (52) has a width greater than a width of the trailing portion (53). A pair of opposed lips (54) and (55) are disposed on the leading portion (52). To fasten the abutment member (50) of the brace (49) to the spacers (1), the leading portion (52) of the fastening means (51) is inserted between a pair of projections {9 and 10} on the spacer. Once the lips (54) and (55) clear the projections (9) and (10), the projections resiliently snap toward their resting position and engage the trailing portion (53) so as to fasten the abutment member (50) to the spacer (1). This is repeated with other spacers (1) as required until the abutment member (50) provides the desired level of support to counter bulging of the concrete containment panels (5).</p> |
