FIG. 1 is a schematic view showing a method for manufacturing a natural stone tone board according to one embodiment of the present invention.

As shown in FIG. 1, in the method for producing a natural stone tone board of the present invention, a stone (2) is embedded in a clay (3) provided in a box-shaped formwork (4) so that a part thereof is exposed. After the removal, the hydraulic slurry (1) is poured into the same mold (4) to cure and harden, and then the clay (3) is removed.

The form (4) is box-shaped as shown in FIG. 1. The size and the like of the form (4) are set as required.

The clay (3) is provided in the mold (4) as shown in FIG. The thickness of the clay (3) can be freely set according to the size of the stone (2) and the thickness of the obtained natural stone plate.

As shown in FIG. 1, the stone (2) is buried so as to be partially exposed in the clay (3). As the stone (2), so-called natural stone may be used, and there is no problem even if it is an artificial stone capable of producing a natural feeling, and various other stones may be used. You can do it.

As a method of embedding the stones (2), the stones (2) may be embedded one by one by hand pressing, or a plurality of stones (2) may be embedded on the clay (3). After arranging stones (2), a plate may be placed on top of the stones and they may be pressed horizontally from above the plate.
In addition, various methods can be adopted.

The hydraulic slurry (1) is embedded in the clay (3) so that the stone (2) is embedded in the clay (3) so as to be partially exposed, and then, as shown in FIG. And cured and hardened. The hydraulic slurry (1) is, for example, a solid material such as cement or aggregate mixed with water as a main component. If necessary, in order to improve the strength of the obtained inorganic plate, Solid materials such as reinforcing materials and fibers are blended as auxiliary components.

As the above-mentioned cement, for example, portland cement, fly ash cement, blast furnace cement and the like are used.

As the above-mentioned aggregate, crushed stones such as granite and serpentine, silica stone powder, shirasu balloon, glass balloon, silica, pearlite, sand, beads and the like are used.

[0017] Pulp powder or the like is usually used as a reinforcing material to be added as required. Further, as the fiber, for example, cellulose-based pulp fiber, mineral fiber such as asbestos, polypropylene, organic resin-based fiber such as vinylon, glass fiber,
Carbon fibers and metal fibers can be used.

As the curing method, for example, at a temperature of about 50 to 90 ° C.
For example, a method such as performing 100-hour wet heat curing,
In addition, it is also possible to adopt a method such as carrying out in an autoclave as occasion demands.

In the present invention, the clay (3) is removed after the hydraulic slurry (1) has been cured and hardened. As a method of removing the clay (3), for example, it may be simply scraped off, or it may be washed off with water or the like. . The removed clay (3) can be recycled for producing the next natural stone board.

According to the present invention, when the hydraulic slurry (1) is poured into the mold (4), the stone (2) is buried and smoothed by adopting such a manufacturing method. 2) does not move, and as a result, when the hydraulic slurry (1) hardens as it is, after removing the clay (3), it is obtained as a natural stone board with a stone (2) laid at a desired position. It is something that can be done. Moreover, when obtained as a natural stone board, the individual stones (2) are embedded in the hardened hydraulic slurry (1), so that the individual stones (2) are hardened with a certain holding strength. Held in slurry (1), resulting in individual stones (2) falling off,
Peeling off is prevented. In addition, the surface of the obtained natural stone board has various exposed portions of the individual stone (2) depending on the size of the individual stone (2). This makes it possible to impart a feeling of unevenness.

That is, according to the present invention, the stone (2) can be easily laid at a desired position, and the surface can be sufficiently imparted with unevenness.

In particular, as shown in FIG. 1, if the stone (2) is buried so that the height of the exposed part of the stone (2) is substantially the same, the stone is obtained as a natural stone board. When the individual stones (2) are buried in the hardened hydraulic slurry (1) at substantially the same depth, the individual stones (2) become hardened hydraulic slurry (1) with a certain holding strength. Thus, the stones (2) are more securely held, and as a result, the individual stones (2) are more reliably prevented from falling off or coming off. Moreover,
According to the size of the individual stones (2), the surface of the obtained natural stone tones becomes more and more reliable in the exposed portions of the individual stones (2). This makes it possible to more reliably impart the surface unevenness.
