摘要

PURPOSE: To present pieces of natural stones by burying almost half of exposed recessed and projected faces on the upper faces of natural stones placed in parallel by equally pressurizing and pressing a cushioning body, and vibrating from a bottom face into a clay layer. ;CONSTITUTION: The adequate number of stone materials S, for example, artificial stones, lava stones, plastic pseudo-stones (hereinafter called as stone materials) for representing a natural stone pattern manifested on the surface of a concrete product are placed in compliance with a sight to be manifested on the exposed faces of a concrete product on a clay layer N formed uniformly in a surface pallet P. Then, recessed and projected stone material surfaces on the upper faces of the stone materials S placed in parallel are pressed uniformly by a cushioning body 21 lowered by a cylinder 2a and buried into the clay layer N. The burying can be carried out stably without moving the stone materials S, as the clay layer is not hard but rather flexible. The shape of the stone materials S can be formed on the clay layer simply by picking up and removing the stone materials S buried in the clay.;COPYRIGHT: (C)1996,JPO
