<p>In the construction of roof terraces, it is known to use special guide- and support-elements for the corner parts of the paving slabs, namely circular plate elements with a cruciform formation of upright support and distance-providing projections. There is a need to be able to stack these plate elements together both for transport and for height adjustment and it is known to configure the plate elements with break-through areas which can accommodate the upright projections on an underlying plate element. However, this requires a mutual turning of the elements, and with the invention this is avoided by configuring the projections in an upwardly tapering manner, and with open cavities downwards which can accommodate the corresponding, underlying projections. The guide- and support-elements can be broken over along the radial rows of projections to form element half parts or quarter segments for the support of two adjoining slab corners or only a single corner respectively. Stacking of the elements can be carried out by a regular stacking of the element parts in columns without any turning mutually between them.</p> |
