PREFABRICATED PILLAR SLAB SYSTEM AND MOLD FOR MANUFACTURING A PREFABRICATED PILLAR SLAB

摘要

A pillar slab system using precast concrete pillar slabs for constructing apillar,pergola or other stone structure comprises a body comprising at least foursides. Eachexterior side surface comprises at least one simulated stone face. At leastfirst and secondside surfaces also have at least one simulated joint defining a visualseparation betweensimulated stone faces. The simulated joints in the side surfaces are disposedat differenthorizontal positions, so that when one pillar slab is stacked on an identicalpillar slab in adifferent orientation, the simulated joints in adjacent surfaces arevertically staggeredrelative to one another to avoid obvious repeating patterns and provide theappearance ofa natural stone construction.
