Abstract

PURPOSE:To mold a combined block of natural stones, which displays an external appearance such as a monolitlic rock as a whole, by a method wherein concrete is placed within a concrete shuttering and a plurality of natural stones are set up into a concrete placement surface so that the natural stones adjoining to one another collide with one another or approaches to one another. CONSTITUTION:A concrete shuttering 1 for manufacturing of a combined block of natural stones is assembled, concrete 2 is placed within the same concrete shuttering 1 and a plurality of natural stones 3 are set up into the surface of the placed concrete 2 prior to curing of the placed concrete 2 so that they adjoin to one another or approaches to one another. Then rock refuse and/or sand 4 of the same quality and color as those of the natural stone 3 is fitted into gaps of the natural stones 3 and laminated and stuck integrally onto the placement concrete 2 surface. Then upon curing of the placement concrete 2 demolding is performed. A combined block A of natural stones manufacture like this displays a scene close to one large natural stone as a whole.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a method for manufacturing natural stone bonded blocks.

(Prior art) Conventional natural stone bonding blocks are made by assembling a plurality of natural stones so that adjacent natural stones collide with each other or are close to each other, and at the same time, the backs of each natural stone are integrated with a concrete block. It is composed of a combination of

(Problems to be Solved by the Invention) In the conventional natural stone bonded block, the concrete surface is exposed in the gap between adjacent natural stones, creating a sense of discomfort, spoiling the landscape, and lacking the artificial feel of natural stone. Ta.

The present invention has been devised in view of the problems of the prior art, and its purpose is to provide a method for manufacturing natural stone bonded blocks that have a simple structure and have a landscape similar to that of natural rocks. It is in.

(Means for solving problem m1) In order to achieve the above-mentioned object, the method for manufacturing a natural stone bonded block according to the present invention includes pouring concrete in a formwork, and pouring a plurality of stones on the surface of the poured concrete. Next, adjacent natural stones of the same type are planted so that they collide with each other or are close to each other, and then rock debris of the same quality and color as the natural stones is placed on the poured concrete surface in the gaps between the natural stones. And/or after laying and adhering sand, the mold is removed from the mold.

(Function) According to the present invention, as described above, concrete is poured in a formwork, and a plurality of natural stones are placed on the concrete pouring surface so that adjacent natural stones collide with each other or are close to each other. By setting the backs of a plurality of natural stones together with concrete, a natural stone joint block body is formed, and then, within the gap formed between each of the natural stones on the poured concrete surface, By laying and gluing rock chips and/or sand of the same quality and color as the natural stone, and then removing the formwork, the concrete surface is not exposed in the gaps between each natural stone, and the whole stone is made into one piece. A natural stone bonded block with an appearance similar to this is molded.

(Example) The present invention will be described below with reference to the illustrated embodiments.

Assemble formwork (11) for manufacturing natural stone combined blocks, (1st
(See figure) Concrete (2) is placed in the formwork (1), and before the poured concrete (2) hardens, a plurality of natural stones (3) are placed on the surface of the concrete (2). ) are planted so that they collide or are close to each other.

(See Figure 3) Next, before the poured concrete (2) hardens, rock debris and/or sand (4) of the same quality and color as the natural stone (3) is inserted into the gaps between the natural stones (3). The cast concrete (2) is then integrally layered and adhered onto the surface of the cast concrete (2) (see Fig. 4), and then removed from the mold after the cast concrete (2) has hardened. (See Figure 5) The thus manufactured natural stone bonded block has a plurality of natural stones (3) protruding from the surface of the concrete block, colliding with each other or close to each other, with gaps between the natural stones (3). The concrete surface is covered with rock debris and/or sand of the same quality and color as the natural stone (3), and the overall appearance is similar to that of a single large natural stone.

Note that rock debris and/or sand (4) of the same quality and color as the natural stone (3) is placed in the cast concrete (2) in the formwork (]).
) is layered on the same concrete after hardening, and is integrally bonded to the same concrete (2) via an adhesive such as mortar (see Fig. 6).Then, the formwork (1) is removed and the above-mentioned It may be molded with the same natural stone bonded blocks as in the embodiment.

(Effects of the Invention) According to the present invention, as described above, when a plurality of natural stones are placed next to each other on the poured concrete surface in the formwork, the same natural stones collide with each other.
Alternatively, they may be planted in close proximity to each other, and rock chips and/or sand of the same quality and color as the natural stones are laid and adhered to the concrete surface in the gaps created between the natural stones, and then removed from the mold. By this method, a plurality of natural stones are protruded from the surface of a concrete block in contact with each other or in close proximity to each other, and the surface of the concrete block in the gaps between the natural stones is covered with rock debris of the same quality and color as each natural stone. and/or coated with sand to produce a natural stone bonded block that, as a whole, has a landscape similar to one large natural stone.
