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 andsecond side surfaces also have at least one simulated joint defining a visualseparationbetween simulated stone faces. The simulated joints in the side surfaces aredisposedat different horizontal positions, so that when one pillar slab is stacked onan identicalpillar slab in a different orientation, the simulated joints in adjacentsurfaces arevertically staggered relative to one another to avoid obvious repeatingpatterns andprovide the appearance of a natural stone construction.
