FIG. 7 shows a partial perspective view of a building interior wall surface. For example, Oya stone wall materials 40 formed into a cube shape having a width of 120 cm, a height of 50 cm, and a thickness of 25 cm are stacked to constitute the inner wall surface of the building. ing. In the raw material stone forming step, the wall material 40 is obtained by mining Oya stone, and using the mined Oya stone using a gang saw, a circular saw, a diamond blade, or the like, so that the square stone material stone having a certain thickness is obtained. It is the same as in the case of the first embodiment described above. Also in the processed stone formation process, the raw material stone formed in the raw material stone formation process is formed into a cube shape having a predetermined thickness, and the front side on the surface side that is stacked and ground is flattened and subjected to surface processing. .

In the surface processing step, a predetermined surface processing for improving the decorativeness is performed. Specifically, a predetermined surface processing is performed on the surface of the processed stone material using a cutting device, a grinding device, or the like. Here, as the predetermined surface processing, diamond finishing processing, rib finishing processing, bishan finishing processing, lattice finishing processing, chain finishing processing, rough finishing processing, split skin finishing processing, and the like are applied. To do.
In the decorative hole forming step, the decorative hole is formed on the surface of the processed stone (wall material 40) that has been subjected to the predetermined surface processing in the surface processing step. Specifically, the surface of the processed stone material is removed by removing the ones exposed on the surface of the processed stone material from the clay minerals contained in the processed stone material (the wall material 40 subjected to the predetermined surface processing). A decorative hole is formed on the surface. In the present embodiment, each decorative hole is formed by cutting a groove using a cutting tool. Here, as the cutting tool, a drill bit, a hole saw, a diamond bit, or a simple tool such as a tapered screwdriver can be used.

In the decoration material arranging step, the decoration material 30 is arranged in each decoration hole (middle mark portion) of the processed stone (wall material 40) in which the hole is formed in the decoration hole forming step. Specifically, the decoration material 30 is bonded to each decoration hole by an adhesive. Here, each decoration material 30 is preferably arranged so as not to protrude outward with respect to the surface of the processed stone material (wall material 40). Moreover, in each hole part, it is preferable to fill the decorative hole part with a transparent resin or the like with the decoration material 30 inserted inside, so that the hole part is completely closed by the resin. .
Each process including the above-described wall material 40 and the surface processing process on the front side thereof is not different from that in the method for manufacturing the coaster 1 of the first embodiment described above. All the methods for applying the decorative material 30 to the surface of the processed stone material of Oya stone excluding the specific shape and structure of the coaster 1 are directly applied to the method for manufacturing the wall material 40 in the second embodiment. .
