Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to concrete products molded from mortar such as plates and tubes, concrete products, and concrete structures such as concrete structures such as building walls, ceiling slabs, and slabs. The present invention relates to a decoration method for decorating the surface of a molded article with a colored pattern.

<Prior Art> Conventionally, the only way to decorate a part or the whole surface of a ready-made concrete molded body with a colored pattern is to draw the pattern with paint such as paint.

<Problems to be Solved by the Invention> However, the pattern painted with paint on the surface of the concrete molded body gradually disappears due to the weather, the bottom of footwear of people walking on it, and cars running on it It is rubbed by such wheels and worn out in a short time.

Therefore, the present invention has been developed for the purpose of expressing a pattern appearing on a part or the whole surface of a concrete molded body in a Kintaro candy style by a pattern layer made of a dried pattern material having a predetermined thickness.

<Means for Solving the Problems> The method for decorating a concrete molded body according to claim 1 is a method for decorating a concrete molded body, comprising: Arranging the aggregates, filling a part or all of the subdivisions of the cell compact with a dry concrete pattern material, supplying water to the pattern material, and solidifying the pattern material integrally with the surface of the concrete molding. It is characterized by.

In the method for decorating a concrete compact according to claim 2, the lower surface of the densely packed cell in which cylindrical small sections of a certain height are gathered adjacent to each other is closed at the bottom, and part or all of the densely packed cell is formed. Fill a small concrete area with dry concrete pattern material, supply water to the pattern material, and apply the upper surface of the pattern material filled in the cell compact to the surface of the ready-made concrete compact, or use the The method is characterized in that the material is released from the mold and applied to the surface of a ready-made concrete molded body, and the pattern material is solidified integrally with the surface of the concrete molded body.

(Embodiment) FIGS. 1 and 2 show a concrete molded body decorated with a pattern according to the present invention.

The concrete formed body C may be formed of mortar or concrete.

The concrete compact C shown in FIG. 1 is plate-shaped, and its surface is modified with a pattern layer 1 of the same size traffic sign laminated on the upper surface thereof.

The concrete molding C shown in FIG. 2 has a pattern layer 1 laminated on a part of the surface thereof, for example, between the soils of a building. Of course, a pattern layer of another pattern following the pattern of the pattern layer 1 may be laminated adjacent to the pattern layer 1 to decorate the entire soil with a continuous pattern pattern.

FIG. 3 shows a densely packed cell for forming the pattern layer shown in FIGS. 1 and 2 described above, in which cylindrical small sections 2 'having a fixed height are gathered adjacently. This small section 2 'is a square or a hexagon (honeycomb) having one side divided by a partition wall, for example, about 1 to 10 mm, and the height is adjusted to the thickness of the pattern layer to be formed.

The pattern layer 1 is formed by filling a part or the whole of the small section 2 ′ of the dense cell body 2 with a dry concrete pattern material, and then supplying and solidifying the water. The dry concrete pattern material is mainly composed of cement powder or resin, or a mixture of these and pigments and fine aggregate.
Even if it contains moisture from absolutely dry, it is not kneaded with water and is a material for pattern layer construction that can be easily loosened and supplied. Fines and other substances may be mixed, or a setting and hardening accelerator, a waterproofing agent, a swelling agent and other admixtures may be mixed.

The decoration of the compact C by the method of claim 1 using the above-mentioned cell compact 2 made of a metal plate, plastic, rubber, wood, paper, non-woven fabric or any other water-insoluble material requires the cell compact. Since the aggregate is removed from above the molded body, the lower surface is opened in addition to the upper surface. If necessary, the dense cell body may be configured so that the outer peripheral portion and the inner portion can be separated from each other so that the outer peripheral portion and the inner portion can be separately removed.

In the case of FIG. 1, the dense cell body 2 is superimposed on the surface of the compact C (FIG. 4), and communicates with the annular portion of the pattern 1 and the annular portion obliquely crossing the inside of the annular portion. Red dried pattern material 1R in the subsection corresponding to the straight line portion, and blue dried pattern material 1B in the subsection corresponding to the two substantially semicircular portions inside the annulus. In the small section corresponding to the outside of the section, the ground color of the pattern, for example, a white dry pattern material 1W is filled with the same thickness.

After filling, remove the dense cell body from the molded body, and supply water to the pattern material so that the required water: cement ratio is achieved with respect to the total amount of cement and resin of each pattern material. Is solidified on the formed body to be integrated with the formed body.

In the case of FIG. 2, the dense cell body 2 is placed on the soil, which is formed as shown in FIG. 5, and the white dry pattern material 1W and the foot of the mountain are formed in a small section corresponding to the portion representing the snow on the summit. Brown dry pattern material 1B in a small section corresponding to the part representing
r, the blue dry pattern material 1B in the small section corresponding to the sea and the sky blue pattern material 1S in the small section corresponding to the sky are filled to the same thickness. In addition to removing the aggregates, an appropriate amount of water is supplied to each pattern material as described above, and each pattern material is solidified on the dirt and integrated with the dirt.

In any of the above-described embodiments, the removal of the cell dense body 2 is not affected by removing the cell dense body after filling all the pattern materials, before supplying water, or after supplying water. Remove as soon as possible not yet solidified.
This is because the removal of the densely packed cells collapses the pattern material between parts separated by the partition walls of the subdivision, and fills the traces of the removed partition walls with the pattern material.
The removal of the dense cell body at this stage may be performed on the whole or on the outer peripheral portion and the inner portion.

In addition, when removing the cell dense body, the cell dense body is vibrated,
When vibrating with ultrasonic waves or pressing with a press when removing the cell dense body and curing all the pattern material, the collapse of the material is forced, and it can promote filling the trace of the partition wall of the cell dense body preferable.

Further, the cell dense body 2 may be made of a material which is soluble in water or other materials. This cell dense body is not limited to a cylindrical one having upper and lower surfaces open because it is dissolved by the water supplied to the pattern material, and the lower surface may be closed at the bottom.

When the surface of the molded body is decorated with the pattern layer 1 as shown in FIGS. 1 and 2 described above, only the step of removing the cell dense body becomes unnecessary, and the rest is the same as the above-described embodiment. The traces of the dissolved and disappeared cell clusters are filled by the collapse of the pattern material in contact with the partition walls. Vibration or pressure may be applied to promote collapse.

According to the method of claim 2, since the lower surface of the cell dense body is closed with the bottom 3 and a part or all of the small area of the cell dense body is pre-filled with the dried concrete pattern material and supplied with water, for example, As shown in FIG. 6 and FIG. 7, a vertical wall which is a concrete molded body, or an uneven surface such as a pipe or a rod formed of concrete can be decorated with the pattern layer 1. The pattern layer 1 in FIGS. 6 and 7 is a family crest or a city emblem, and the pattern layer in FIG.
In order to form a black dense pattern material 1Bl in a small section corresponding to the portion representing the double-drawn pattern of the cell dense body,
As the background color of the pattern in the subsection corresponding to the other parts,
For example, the yellow dried pattern material 1Y was filled to the same level as the upper surface of the cell densely packed body, and a part was demolded as necessary, and an appropriate amount of each material was supplied with water. The pattern material removed from the upper surface of the pattern material or from the cell mass is pressed against the wall surface (FIG. 8), kept in that state by appropriate means, and each pattern material is solidified and integrated with the wall surface. As for the removal of the cell dense body, the pattern to be expressed is not impaired even if the cell dense body is removed after filling all the pattern materials, before supplying water, or after water supply, as in the case of claim 1. At the stage where it is not yet solidified, the entire cell dense body or one of its outer peripheral portion and the inner portion is removed as soon as possible.

When the cell mass is made of a material that is insoluble in water, it is necessary to remove the cell mass from the wall surface as described above before the pattern material hardens. If it is made of an oblate or other water-soluble material, it does not need to be removed because it dissolves.

As shown in FIG. 7, in order to form the pattern layer 1 on the surface of the molded article which is not flat, the cell dense body 2 may be either non-deformable or made of urethane rubber or other deformable material. Use flexible sheets and plates such as rubber, plastic, non-woven fabric and metal plates.

Then, similarly to the above, the pattern material 1Bl, 1Y is filled in a small section addressed to a part of the cell dense body, and after an appropriate amount of water is supplied, the compact C is placed on the surface of the pattern material. In this case, the compact is made of concrete. Since it is a cylinder, the mold is pressed and wound on the surface of the cylinder while rolling the molded body (FIG. 9), and in this state, each pattern material is solidified and integrated with the outer periphery of the molded body. As described above, the removal of the cell dense body is the same as that of the first aspect. The pattern layer 1 can be formed on the entire outer periphery of the molded body by setting the length of the cell dense body to be the same as the circumferential length of the outer periphery of the molded body. The molded body is provided with a flange as shown in FIG. 10. When the flange is integrally or detachably placed, the roll is easy to roll and the finish is beautiful.

Also in this case, when removing the cell dense body, vibrations are applied when removing the cell dense body, or the pattern of the pattern material is pressed against the surface of the molded body. Can be filled with pattern material.

Further, in both the first and second aspects, when filling the pattern material in the partition of the cell dense body, if vibration is applied, the packing density of the pattern material is increased, and a dense pattern layer is obtained. Further, the filling of each pattern material into the subsections 2 'can be performed manually or by a robot. However, for accurate and quick filling, the openings corresponding to the pattern and having the same size as the cell dense body are used. It is preferable to use a mask that has a portion and that is closed except for the opening.

For example, since the pattern of the molded body in FIG. 1 includes a red pattern and a blue pattern, as shown in FIG. 3, a mask MR having an opening R corresponding to the red pattern and an opening corresponding to the blue pattern A mask MB having a portion B is used. Both masks have the same outer shape as the cell dense body 2, and when correctly overlapped on the cell dense body 2, the respective openings R and B can express the respective patterns of red and blue.

Therefore, one of the masks, for example, MR is first superimposed on the cell dense body, the red pattern material 1R is filled into the required small sections through the opening R, and then the mask MR is removed, and the mask MB is replaced with the cell dense. Overlaid on the aggregate, through the opening B blue pattern material 1B
May be filled in other required small sections, and the mask MB may be removed.

Thus, the dried pattern material can be quickly and accurately filled into the required small sections in the cell compact.

<Effects of the Invention> According to the present invention, a Kintaro candy-type pattern layer can be formed on a part of or the entire surface of a ready-made concrete molded product to decorate the surface of the molded product. And even if the surface of the pattern layer is worn, the expressed pattern does not disappear or become unsightly.

In addition, since the pattern layer is formed of a dry pattern material that fills a part or the whole of the partition in the cell dense body, it can be filled with a gap without any gap, and the trace of the removed or lost cell dense body is a pattern material. , The boundary of the pattern can be expressed minutely, and a very clear pattern can be obtained.

Furthermore, since the pattern material is dry, if it is incorrectly filled, it can be easily removed and repaired using a vacuum cleaner-type tool.
