Abstract (en)
[origin: WO02078920A2] The invention relates to a mould for producing pre-cast concrete units, in particular paving stones, comprising a lower mould section consisting of a mould cavity block (1) and side sections that are screwed thereto. The mould cavity block (1) has an internal area (4) comprising mould cavities (6, 7) and an edge area (5), on at least part of which recesses (13) are provided. An efficient method of production and suitability of the mould for hardening are achieved by a constant thickness of the mould cavity block (1), by recesses (13), that create intermediate webs (24) with a web width (S) that remains approximately constant, by recesses (13), which are partly configured in the edge area (5, 11, 12) as undercut grooves (15, 16) and by the screwing of the side sections crosswise to the course of the undercut groove (15, 16).
