Abstract

PURPOSE:To obtain a block, on the surface of which native rocks appear by a method wherein water is poured onto sand, which is placed on rocks laid on the bottom surface of a box-like from, and, after the pouring and small rocks are laid on the sand and further sand is placed on the samll rocks and water is poured again, concrete is placed and finally demolded. CONSTITUTION:The bottom surface of a form 1 preferably has small holes, through which water can flow out. A large number of rocks 2 are laid on the bottom surface of the form 1. Sand 3 is placed on the rocks. Water is poured onto the sand 3, resulting in running of the sand 3 between the rocks 2 so as to pile up some part of the sand 3 on the bottom surface of the form 1. Next, small rocks 4 are laid on the rocks 2, after sand 3 is placed on the small rocks 4, water is poured again on the sand 3. The sand 3 at the top surface pushes the small rocks 4 in between the rocks 3 and piles up on the bottom surface and between the rocks just above the bottom surface. After the water is discharged from the form 1, concrete 5 is placed in the form. The concrete 5 reaches the rocks 2 at the lower part of the form and hardened. By demolding after hardening, the sand layer formed on the bottom surface come off, resulting in obtaining al block, on the surface of which the rocks 2 emerge in the projected and recessed state.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a block manufacturing method, and more particularly to a block manufacturing method in which natural stone is exposed on the surface of the block.

[0002]

2. Description of the Related Art As a method of manufacturing a block of this type, it is easily assumed that stones are arranged on the bottom of a mold having an open upper surface and concrete is placed on the stone to manufacture the block. it can. However, some of the stones are exposed on the surface of the block manufactured by this manufacturing method, but concrete appears between the stones on the surface, and no natural uneven surface appears on the surface. You can't expect beauty.

Therefore, concrete hardly appears on the surface of the block, and stones arranged side by side appear, which causes technical problems to be solved in order to expect natural beauty. Aims to solve the problem.

[0004]

The present invention has been proposed in order to achieve the above-mentioned object, and stones are juxtaposed on the bottom surface of a box-shaped mold having an open top surface, and sand is put on the top surface thereof. afterwards,
After pouring water from the upper surface of the sand, pebbles are laid on the upper surface, sand is poured again on the upper surface of the pebbles, water is re-injected from the upper surface, and then concrete is poured, The present invention provides a block manufacturing method characterized by producing by removing from the mold after curing.

[0005]

[Operation] A large number of stones are laid side by side on the bottom of the mold whose top is open. Then, sand is put from above and water is poured from above the sand. The water pushes the sand downwards and allows it to enter between the laid stones, and a part thereof reaches the bottom surface of the mold. Next, a large number of pebbles are laid on the upper surface of each of them, and sand is put again on the upper surface of each of the pebbles of the same, and water is poured again from the upper surface. In that case, the water causes the sand on the upper surface to flow downward, causing the pebbles to intervene between the stones at the bottom according to the flow of the sand, and part of the sand may be stones like these stones and pebbles. It passes through the space and deposits on the bottom of the mold. Therefore, when concrete is cast in the mold, the concrete mixes the pebbles, and a part of the concrete flows down to the space between the stones in the lower part and hardens. After that, if the mold is removed, the sand accumulated on the bottom of the mold is released, the natural stone appears as unevenness on the surface of the block, and the back part of the stone is hardened integrally with concrete with the pebbles. The stone on the surface does not detach from the block.

An embodiment of the present invention will be described in detail below with reference to the drawings. 1 to 8 are explanatory views showing respective manufacturing steps of the present invention, FIG. 9 is a perspective view of a block manufactured by the manufacturing method of the present invention, and FIG. 10 is a vertical side view of the block. FIG. 1 shows a mold 1 for manufacturing a block, which is generally made of wood and may have minute holes or the like on the bottom surface 1a to allow water to flow to the outside. In the mold 1, as shown in FIG.
A large number of stones 2, 2, ... Are laid side by side on the bottom surface 1a of the mold 1. Natural stones may be used for the stones 2, 2 ...

Next, as shown in FIG. 3, sand 3, 3, ... Is put on the upper surfaces of the laid stones 2, 2, ... And, as shown in FIG. Pour water. The water W passes through the sands 3, 3 between the stones 2, 2, and a part of the water W is deposited on the bottom surface 1a of the mold 1. Therefore, the lower parts of the stones 2, 2 ... Are buried in the sand layer deposited on the bottom surface 1a of the mold 1.

Next, as shown in FIG. 5, pebbles 4, 4 are laid on the upper surfaces of the pebbles 2, 2 ... And sand 3 is again placed on the pebbles 4, 4 laid as shown in FIG. , 3, ...
Next, as shown in FIG. 7, water W
Water again. In that case, pour water on the top sand 3,
3 pushes the pebbles 4, 4 ... between the lower stones 2, 2 ... and deposits them on the bottom surface 1a and immediately above the stones 2, 2. Then, when the water in the mold is discharged to the outside, concrete 5 is poured into the mold 1 as shown in FIG.
The lower part of the concrete 5 includes the small stones 4, 4 ... And reaches the space between the lower stones 2, 2 ,. There, the stones 2, 2 ... Are integrated with the pebbles 4, 4 ... by the concrete 5. Then, if the mold 1 is demolded, as shown in FIG.
Further, as shown in FIG. 10, the sand layer formed on the bottom surface 1a of the mold 1 is detached, and the block 6 having the stones 2, 2 ...

The present invention can be modified in various ways without departing from the spirit of the invention, and it goes without saying that the invention extends to the modified version.

[0010]

Since the present invention goes through the manufacturing process as described in detail in the above-mentioned one embodiment, the stones laid side by side on the bottom surface of the mold are integrated with the pebbles in the back portion by concrete. Therefore, the stone never escapes from the block, and a natural stone having an uneven surface appears on the surface of the block, so that it is possible to expect an expression of natural beauty completely different from that of the conventional block.
