| (54) | A spacer and method of ensuring a gap between kerb stones |
| (57) Kerb stones 1 by their nature are heavy and unwieldy articles which are difficult
to accurately manipulate and align. Nevertheless, it is desirable to provide a predetermined
gap between adjacent end edges of kerb stones for drainage and expansion. This problem
is further exacerbated when higher rates of kerb stone laying are required. A spacer
22, 31, 41, 52, 62, 82 is provided having significant radial components to ensure
that an accurate gap is provided between adjacent kerb stone 1 edges. The spacer members
take the form of typically a cross in order to ensure accurate spacing in the crossed
axes X and Y as the two kerb stone edges are brought together. Typically, a spacer
is secured to one kerb stone edge and then brought into abutment with an adjacent
kerb stone edge to ensure accurate alignment and spacing. Possibly, a dangler or positioning
tag 23 is provided to ensure appropriate location upon the kerb stone edge. |
