Description

The present invention relates to a method for producing a concrete block that can be installed in combination with a pattern resembling a flower pattern or insect (dragonfly, bee, butterfly) as a point or decoration, for example, in a lawn garden of a general household.

In recent years, there are many examples of applying various patterns and colors to gardens, parks, embankments, etc. of ordinary households to improve the scenery. Many conventional examples of the manufacturing method are known, but a manufacturing method that is simple and inexpensive and that can be manufactured even by relatively unskilled workers is not known.
Conventionally, for example, a manufacturing method is known in which a natural or artificial decorative material is embedded in concrete and a decorative material in which a part of the decorative material protrudes from the surface of the concrete is embedded.
However, since the color of the decoration material is exposed compared to the concrete block surface coated with pigment, there is no risk of fading, but it is necessary to remove the material that temporarily fixes the decoration material after placing the concrete. However, there is a drawback that the number of steps increases and the cost increases.

JP-A-9-216210

The present invention provides a method for producing a concrete block which is not used for a conventional decorative material and contains a pigment in a concrete material, but which is not faded and is simple to manufacture and does not require skill, and is decorated with a large number of forms and colors. suggest.

The present invention, first,
Concrete block obtained by adding water and kneading white cement and pigment to the required color ratio, pouring into a cylindrical formwork of the desired form, removing from the formwork and cutting to a predetermined thickness Is a single component piece, a plurality of component blocks or a combination of concrete blocks of different forms, and the concrete block component pieces having respective colors are arranged and fixed in a predetermined form.

Second,
Add a mixture of water and white cement and pigment to the components that make up the abstract or concrete form, knead it with water, pour it into the cylindrical form of the desired form, and remove it from the form. Manufactured to a predetermined thickness by cutting,
Each concrete block is made into one component piece, and the component pieces are combined with multiple or different forms of concrete blocks, and the concrete block pieces of each color are arranged in an abstract or concrete form and fixed. Is the method.

Since the present invention is manufactured by kneading white cement and pigment into the material of the concrete block, unlike the conventional coloration of the surface of the concrete block, the predetermined color fades and peels off due to wind and rain. And long life can be maintained.
In addition, it is possible to easily obtain colored concrete block pieces simply by cutting a concrete bar solidified into a rod shape to a predetermined thickness, so that no skill is required for production and no special equipment is required.

FIG. 1 is a diagram showing an example in which a landscape is improved by combining concrete block pieces and embedding them in a lawn of a garden imitating a geometric form such as a geometric pattern, a floral pattern, or an insect. This concrete block combination is composed of a member 1 cut from a cylindrical shape, a member 2 obtained by cutting a concentric circular ring, and a number of members 3 obtained by cutting an asymmetric ellipse, each of which is red, yellow, Colorful colors such as white are given.

Each of these members 1, 2, and 3 has shown a cross-sectional form, and when it is formed of concrete, it is manufactured by using a mold having a predetermined length and is cut by a concrete cutter or the like.

Next, the manufacturing method of each structural member of a concrete block is demonstrated. First, as shown in FIG. 2, as shown in FIGS. 2 and 3, a mold 10 in the form of a partial ellipse (egg-shaped) is prepared. The material of the mold 10 is not limited as long as a predetermined mold such as a metal press, cast iron, or synthetic resin can be formed. The formwork 10 can take a structure that is divided according to the complexity of the division (10a, 10b), division, etc. The length of the mold 10 can be a length that is easy to handle, for example, about 1 to 2 meters. If it is made of metal, the length of the mold itself becomes heavier and difficult to handle, so about 50 cm to 1 meter is appropriate. In the example of FIG. 2, the inner surfaces 11 a and 11 b are formed so as to have a form imitating a petal. Reference numeral 12 denotes a mating surface, and 13 an assembly bolt. Then, the inner surface of the mold 10 is cleaned and assembled with bolts 13 and nuts.

Next, white cement, sand and pigment are measured at a predetermined ratio, for example, 75% of sand is added to 25% of white cement, and the pigment is added within 10% of the amount of white cement, and is kneaded for about 1 to 2 minutes. (Weight ratio). Then, wash sand and white cement containing pigment are put into a concrete mixer and kneaded sufficiently (for example, for 3 to 5 minutes), and an appropriate amount of water is added and further kneaded for about 3 to 5 minutes.

Next, the color mortar that has been kneaded into the mold 10 shown in FIGS. 2 and 3 installed in the vertical direction in advance is poured in about half first, and then tightened by the first vibrator. After about half of it is poured, it is tightened by the second vibrator. Finally, finish the upper end flat with a hammer.

When the color mortar charged into the mold 10 is sufficiently solidified, the color mortar rod 15 appears as shown in FIG. 3 by removing the mold 10. In addition, since the curing days differ depending on the outside temperature, an appropriate solidification day is selected.

The color mortar columnar body 15 removed from the mold 10 is dyed entirely with the mixed pigment. Accordingly, the columnar color mortar columnar body 15 is placed sideways and, as shown in FIG. 4, is placed on a cutter 20 with diamond foil and cut to a predetermined thickness. When the concrete block piece is embedded in the soil surface, the thickness may vary depending on the nature of the soil.

The concrete block piece made of color mortar formed in a round shape in this way has a form dyed entirely with a pigment. And the concrete block piece manufactured by the above manufacturing method can be combined with several, or with the concrete block piece manufactured with the formwork which has another cross-sectional form, and can be integrated in the ground, as shown in FIG.

First, dig a hole that is slightly larger than the concrete block built-in form (flower pattern) at an appropriate location on the ground, and then flatten it by sanding and solidifying the bottom surface. And fix the position by embedding sand or soil in the gap. If necessary, the height of the concrete block may be as high as the ground, and when replacing with paving stones, the entire concrete block piece may be set higher by about 2 to 3 centimeters.

When it is laid on the ground, when it is made into a floral pattern, as shown in FIG. 1, it is composed of two concentric members and several petal members, so a formwork for each member is required. In addition, corresponding pigments are prepared in order to obtain necessary colors, and concrete block pillars are molded and cut to a predetermined thickness by the above-described manufacturing methods.

Further, in order to realize a form imitating an insect such as a dragonfly, as shown in FIG. 5, a small round concrete block piece 31 having a black color corresponding to the eye and a round concrete block piece 32 having a red color corresponding to the trunk, 2 to 3 types of round concrete block pieces 33 of red color corresponding to the tail, and oblate concrete block pieces 34 of white color corresponding to the blades are respectively produced by the above-described manufacturing method. And it is realized by laying and fixing on the ground in the form of a dragonfly.

In the concrete block body described above, the concrete block pieces as the respective members are fixed to the ground to have a specific form (flower pattern, dragonfly, etc.).

Next, a method for producing a concrete block in which a specific form (flower pattern or the like) is made at the manufacturing stage and it is not necessary to stuff sand / earth into the gaps between the concrete block pieces when embedded in the ground will be described.

Each concrete block piece to be an individual member is secured by the above-mentioned manufacturing method, and then, as shown in FIG. 6, a division that secures the same thickness as a circular and individual concrete block that can cover the outer shape. An annular formwork 40 having a structure is prepared, and concrete block pieces are arranged inside the formwork 40 in a specific form (flower pattern or the like). In the gap, another color mortar is embedded and fixed. The solidified concrete block body has a large disk shape as a whole, but has a specific form and color (flower pattern, dragonfly, etc.).

The large disk-shaped concrete block body manufactured in this way can be embedded in the ground such as soil. However, after it is installed in advance on the newly installed concrete or asphalt surface, the surrounding area is made of concrete or asphalt. Can be represented like a one-point mark on the entire site surface.

Next, concrete block pieces, which are individual members of each form (flower pattern, etc.), are cut into a thickness of about 1 centimeter, and bonded to buildings, road walls and other concrete walls with cyanoacrylate It can be pasted with an agent to form a predetermined pattern or the like, which can contribute to the improvement of the landscape of buildings and roads.

The concrete block manufactured by the method of the present invention is used by being embedded in a soil garden, a concrete asphalt surface, or a building entrance surface. Furthermore, it can be used by being embedded or pasted on the outer wall of a building or road wall.
