PRODUCTION OF LAMINATED MEMBER OF NATIVE ROCK

PURPOSE:To simplify the production and application by arranging extremely thin natural stone pieces to form a pattern through a separable material in a molding frame and pouring a joining material from the rear side and backing a reinforcing material at the rear face of the stone piece to integrate it as a unit. CONSTITUTION:Extremely thin natural stone pieces 1 are arranged to form a pattern through a separable member 2 like a separable paper or synthetic resin sheet in a molding frame and a joining material 3 of Portland cement or epoxy resin is poured from the rear side to fill up the joints. It is also backed with a reinforcing member 4 and sand 5 is scattered before the joining material 3 is cured. After curing of the joining material 3, the frames and the separable members are removed. The laminated member of native rocks is produced in a short time not through a site construction work. In this way, the laminated member of native rocks with a mosaic pattern on the surface can be produced without employing any skillful technicians.
