Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a method for producing a natural stone-bonded block.

(Prior Art) A conventional natural stone-bonding block is a method in which a plurality of natural stones are aggregated so that adjacent natural stones collide with or come close to each other, and the backs of the natural stones are integrated with a concrete block. It is composed by combining.

(Problems to be Solved by the Invention) In the conventional natural stone-bonding block, the concrete surface is exposed in the gap between the adjacent natural stones, which causes an uncomfortable feeling, impairs the landscape, and has no artificial natural stone taste. It was

The present invention has been proposed in view of the above problems of the prior art, and an object of the present invention is to provide a method for manufacturing a natural stone-bonded block that has a simple structure and presents a landscape close to that of natural rock. .

(Means for Solving the Problems) In order to achieve the above-mentioned object, the method for producing a natural stone-bonded block according to the present invention comprises laying a jelly-like substance or clay on the inner bottom portion of a mold, and then the same jelly-like substance or Place a plurality of natural stones through the clay layer on the bottom of the mold so that adjacent natural stones collide with each other or come close to each other, then place concrete in the mold, After removing the jelly substance or clay layered on the concrete surface by demolding after hardening the installed concrete, on the concrete surface in the gap of each natural stone, the same quality as the natural stone, debris of the same color and It is configured to lay and / or bond sand.

(Operation) According to the present invention, as described above, before the concrete is poured into the mold, a jelly-like substance or clay is laid on the bottom of the mold to penetrate the jelly-like substance or clay layer. Then, a plurality of natural stones are installed on the bottom surface of the mold so that the adjacent natural stones collide with each other or come close to each other, and then they are placed in the mold by the jelly-like substance or the clay layer. The concrete layer is divided into layers to prevent the natural stones from being entirely buried in the concrete during demolding.

Then, concrete is poured into the formwork, and by removing the mold after hardening the cast concrete, part of the natural stone is embedded and fixed in the concrete layer, and the rest is in the jelly-like substance or clay layer. The buried block is molded.

Next, the jelly-like substance or clay layered on the concrete surface in the block is removed to cause a part of the plurality of natural stones to project from the concrete surface.

Then, by laying debris and / or sand of the same quality and color as the natural stone on the concrete surface within the gap of each natural stone and adhering to the concrete surface, it is close to one large natural stone as a whole. It manufactures natural stone-bonded blocks that present a landscape.

(Examples) The present invention will be described below with reference to illustrated examples.

Assemble the mold (1) for molding natural stone blocks, and then lay a jelly-like substance such as agar or clay (2) on the bottom of the mold (1) (see Fig. 2). ) Next, place multiple natural stones (3) on the bottom of the mold so that the natural stones (3) adjacent to each other are in contact with or close to each other so as to penetrate the layer of jelly-like substance or clay (2). Install it so that it is positioned and place concrete (4) in the mold (1) (see Fig. 3) Demolding the form (1) while hardening the same concrete (4) Then, a part of each of the natural stones (3) is buried and fixed in the concrete (4), and the rest is the jelly-like substance or clay (2).
The concrete block (A ') embedded in the layer is molded. (See FIG. 4) Next, the jelly-like substance or the clay (2) is removed by a means such as jetting of pressurized water, and a part of the natural stone (3) is projected on the surface of the concrete (4). (See FIG. 5) Next, each of the natural stones on the surface of the concrete (4)
In the gap of (3), debris of the same quality and color as the natural stone (3) and /
Or laying sand (5), adhere to the surface of the concrete (4) with an adhesive (6) such as mortar, the surface of the concrete (4) block, a plurality of natural stones (3) butt against each other, or The gap between the natural stones (3) on the block surface of the concrete (4), which are projected so as to be close to each other, is the same as the natural stones (3).
A natural stone-bonded block (A) with a landscape close to one large natural stone, which is covered with debris and / or sand (5) of the same quality and color, is produced. (Refer to FIG. 6) (Effects of the Invention) According to the present invention, as described above, the jelly-like substance or clay for partitioning concrete in the formwork is laid on the bottom of the formwork, According to the present invention, a plurality of natural stones are installed so as to be in contact with or close to each other on the bottom surface of the mold through the substance or clay layer. Since the natural stone is directly installed on the bottom of the formwork, the natural stone can be installed easily and surely as compared with the case where the natural stone is planted in the cast concrete in the formwork. The natural stone does not get stuck in the concrete before hardening.

Further, according to the present invention, the jelly-like substance or clay layer laid on the bottom of the formwork is well compatible with natural stones and can be deformed in response to unevenness of natural stones. By arranging variously in top, bottom, left and right, the required pattern,
Easy to shape.

According to the present invention, concrete is then poured into the formwork, part of the natural stone is embedded and fixed in the concrete by demolding after the cast concrete is hardened, and the rest is a jelly-like substance or Since a concrete block embedded in clay is molded, by removing the jelly-like substance or clay, a concrete block in which a part of natural stone is projected from the concrete surface is molded.

The present invention, in the gap between the natural stones in the concrete surface of the block, the same quality as the natural stone, laying debris and / or sand of the same color system, by bonding to the concrete surface via an adhesive, A plurality of natural stones are projected on the surface of the concrete block, and the surface of the concrete block in the gap between the natural stones is covered with debris and / or sand of the same quality and the same color as the natural stone, and the whole is one piece. The natural stone-bonded block that produces a large natural stone landscape of is manufactured.

Claims (1)

[Claims] 1. A jelly-like substance or clay is laid on the bottom of the formwork, and a plurality of natural stones that are adjacent to each other are pierced through the jelly-like substance or clay layer on the bottom of the formwork. Installed so as to be in contact with or close to each other, then concrete was placed in the mold, and after the cast concrete was cured, it was demolded to remove the jelly-like substance or clay layered on the concrete surface. After that, a debris and / or sand of the same quality and color as the natural stone is laid and adhered to the concrete surface in the gap between the natural stones, and the block is bonded to the natural stone.
