Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to polished walls used in high-class restaurants, temples, etc., for use as exterior walls and interior walls of buildings, or interior decorative walls. More specifically, it relates to a polished wall construction method that can create a pattern on the surface.

<Prior art> As polished walls, polished walls such as black Otsu walls called polished Otsu and plaster polished walls have been known for a long time.

This type of polished wall is made by mixing slaked lime with colored clay such as Inari-gami and Kyoto white clay, and also using Sarashizusa, Shizusa, etc. as an admixture material.
Mix binder materials such as Misinzusa and Gizusa, add water and knead them, and apply the kneaded mixture to the surface of wall soil with a thickness of 20 meters or more in a thickness of about 2 to 4 meters. Apply,
It was obtained by polishing the coated wall surface in an uncured state, so-called semi-dry state, by polishing the same area about 30 times with a metal trowel, etc. over a period of time.

<Problems to be Solved by the Invention> However, conventional polished walls tend to crack when the surface is polished, require skilled plasterers, and are expensive.

Furthermore, after applying the kneaded material, it must be kept in an uncured state, and the kneaded material must be coated for a distance of, for example, 1 m! Because it takes a day to polish, it is not possible to apply the kneaded material over a wide area in advance and then polish it later.For this reason, it is only possible to finish small areas at a time, which requires time and manpower. However, it has the drawback of being expensive.

By the way, the beauty of decorative walls can be further enhanced by adding patterns to the surface. Traditionally, small shells, etc., have been scattered in a spiral pattern and embedded in the wall surface, and various types of arabesques etc. However, as mentioned above, the polished wall itself is prone to cracking, and scattering shells etc. there requires even more skill and time. Creating a pattern on the surface of a wall was not only difficult, but also extremely expensive.

The present invention was made in view of the above circumstances, and an object of the present invention is to make it possible to obtain polished walls with patterns on the surface in a short time and at low cost without causing cracks. do.

<Means for Solving the Problem> In order to achieve the above-mentioned object, the polished wall construction method according to the invention of claim (1) involves adding water to diatomaceous earth, slaked lime, and carbon fibers and kneading them. The method is characterized in that it produces a polished wall with a pattern on its surface by applying the kneaded product to the surface of an uneven base material and polishing the surface in an uncured state of the applied material.

Furthermore, the polished wall construction method according to the invention of claim (2) is as follows:
In the polished wall construction method according to the invention of claim (1),
It is characterized by forming irregularities on the surface of the base material by arranging leaves or shapes of plants on the surface of the base material.

Furthermore, the polished wall construction method according to the invention of claim (3) is as follows:
After applying the curable kneaded material to the surface of the base material, the coated layer is made uneven and dried to form an uneven base material surface. By applying the kneaded material by adding water and polishing the surface while the applied material is in an uncured state,
It is characterized by producing polished walls with patterns on the surface.

As diatomaceous earth, one produced in Noto, Ishikawa Prefecture can be used.

This polished wall may contain a predetermined pigment depending on the color of the wall to be obtained.

For example, red pigments include synthetic iron oxide (Fezes), which contains ferric oxide, and red pigment (Fat's).
, cadmium red (CdS-, nCd5e) can be used, and as a yellow pigment, synthetic iron oxide (Fezes) containing ferric oxide or loess (S i O,.
Al1tOs), barium ocher (BaCrOa) can be used, and as a green pigment, chromium oxide (Cry's>
can be used, and as a blue pigment, cobalt blue (Co
O-A f z Os) and ultramarine [2 (Alz Os ”
Na, 0' 2S 1ot) Na.

S, ] can be used.

As the slaked lime, dolomite plaster, which is a dolomite-based slaked lime that is a complex of calcium and magnesium hydroxides, can be used. Dolomite plaster has a particle structure with a good distribution of fine and coarse particles, so it has excellent water retention and workability, and also has the advantage of being able to be painted without using glue. ing.

According to the present invention, it is possible to build a normal polished wall by applying the kneaded material to the base material and polishing its surface, or by using a mold as the base material and applying the kneaded material inside the mold. The surface can also be polished to create a tile-like article with a polished surface. In the latter case, tile-shaped polished walls of predetermined dimensions can be manufactured in advance and then attached to the constructed building later, which has the advantage of improving construction efficiency.

There are various methods of polishing, such as simply polishing the surface of the uncured object with a metal trowel, pressing the surface firmly and then polishing, or even polishing with a slight pressure. Polishing methods can be applied. It is more preferable to polish while applying pressure.

The thickness of the kneaded product may be sufficient as long as the pattern can be formed on the wall surface, and is preferably about 1 to 5 m, but is not limited to this range.

<Function> According to the configuration of the polished wall construction method according to the invention of claim (1), as a result of various studies, diatomaceous earth is used in place of colored soil, and carbon fiber is added as a binding material. By this method, it is possible to obtain a polished wall that has high strength and can develop a good gloss on the surface with a short polishing work.In addition, by providing unevenness on the surface of the base material, the boundary between the unevenness can be obtained. It is thought that as the surface is coated, there is a difference in the pressure applied to the coated object in the vicinity, and a difference appears in the state of gloss development at the boundary, resulting in the appearance of the pattern.

Further, according to the configuration of the method for constructing a polished wall according to the invention of claim (2), a pattern can be directly expressed by the leaves themselves of plants such as autumn leaves.

Moreover, according to the structure of the method for constructing a polished wall according to the invention of claim (3), it is possible to form irregularities on the base material itself and to express a pattern of a desired shape.

<Example> Hereinafter, an example of the present invention will be described in detail based on the drawings.

1st Journey ■ 100 parts by weight of calcined diatom ± (powdered color with a particle size of about 10 to 40 μm) and 50 parts by weight of dolomite plaster (white powdered with a particle size of 1 to 100 μm). are mixed, and the average fiber length is 3w in the mixture.
Add 5 parts by weight of carbon fiber (S-231, manufactured by Donuc Co., Ltd.) having a fiber diameter of 13 μm at ta, and mix for several minutes using a mixer such as an omni mixer to preliminarily disperse the mixture.

To this preliminary dispersion, 40 parts by weight of water and 5 parts by weight of loess (Si02 .Al t Os) as a yellow pigment are added and kneaded.

Then, as shown in the cross-sectional view of FIG. 1(a), a mortar 2 as a curable kneaded material is applied onto the base concrete 1 to form a base material 3.

Next, as shown in the cross-sectional view of FIG. 1(b), after the mortar 2 has hardened or has hardened to some extent, autumn leaves 4, which are examples of leaves of plants, are applied to the surface of the base material 30.
．． 4 to form an uneven base material.

On the surface of the base material 30 on which the leaves 4.4 of the autumn leaves are pasted, the thickness of 2 to 31 is applied over the entire surface including the leaves 4.4 of the autumn leaves, as shown in the cross-sectional view of (c) in FIG. Then, the above-mentioned kneaded material 5 mixed with carbon fiber is applied using a metal trowel or the like.

Thereafter, after 0.5 to 1 hour has elapsed, the kneaded material 5 is in an uncured state where it has started to harden, and the entire kneaded material 50 is strongly pressed with a metal trowel, and the surface of the kneaded material 50 is polished.

By repeating these pressurized polishing operations 4 to 5 times, a wall with whitish embossed patterns 4a and 4a of the autumn leaves corresponding to the leaves 4.4 of the autumn leaves is produced, as shown in the front view of Fig. 2. can. Due to pressure polishing, there is a difference in the pressure applied to the kneaded material 5 between the leaves 4.4 and other parts of the autumn leaves, so this pressure difference seems to cause a difference in the coloring state. .

If you finish polishing while the water is still uncured within two hours of drying, you will have a glossy wall with no cracks.

Two days after this polishing work, the wall was completely cured, and a glossy yellow polished wall with no cracks and with a pattern of autumn leaves (m4a) standing out on the surface depending on the shading was formed.

Comparative Example> A wall was produced in the same manner as in the above example except that the carbon fibers were omitted.

In this comparative example, cracks appeared immediately after the polishing work started, making it difficult to polish.Although the finished wall was yellow in color, there were many cracks, making it difficult to create a beautiful wall surface. . In addition, it is difficult to polish the pattern sufficiently with a metal trowel, and it is difficult to make the pattern stand out.
The product value was extremely low.

Therefore, in this comparative example, if cracks were to be avoided, polishing had to be done with relatively little force and over a long period of time.

From the above comparison results, it was clear that according to the examples of the present invention, high quality polished walls could be obtained easily and in a short time.

As shown in the cross-sectional view of (a) in Figure 3, the base material 3 is composed of the base concrete 1 and the mortar 2 is applied as a hardening mixture. Before hardening, the mortar coating layer is provided with a spiral pattern of depressions and depressions 6 using a scrubbing brush or the like to form an uneven base material.

Next, as shown in FIG. 3(b), the same coating as in the first embodiment was applied to the entire surface of the base material 3, including the spiral pattern unevenness 6, to a thickness of 2 to 3 all. The thus obtained kneaded material 5 mixed with carbon fibers is applied using a metal trowel or the like.

Thereafter, after 0.5 to 1 hour has elapsed, the kneaded material 5 is in an uncured state where it has started to harden, and the entire surface of the kneaded material 5 is strongly pressed with a metal trowel, and the surface of the kneaded material 5 is polished.

By repeating these pressure polishing operations 4 to 5 times,
As shown in the front view of FIG. 4, the spiral pattern 6a...
・Produces a wall with a whitish appearance.

■11 ships■ As shown in the cross-sectional view of (a) in Figure 5, the mortar 2 dries to the base material 3, which is made by applying mortar 2 as a hardening mixture onto the base concrete 1. Before curing, speckled 8W-like unevenness 7 is applied to the mortar coating layer using a roller or the like having protrusions at a predetermined pitch on the outer peripheral surface to form a base material with unevenness.

Next, as shown in FIG. 5(b), the surface of the base material 3 is coated over the entire surface including the irregularities 7 in a spotted pattern.
A kneaded material 5 mixed with carbon fiber obtained in the same manner as in the first embodiment is applied to a thickness of 2 to 3 m using a metal trowel or the like.

Thereafter, after 0.5 to 1 hour had elapsed, the kneaded material 5 was cured and in an uncured state, the entire surface was strongly pressed with a metal trowel, and the surface of the kneaded material 5 was polished.

By repeating these pressure polishing operations 4 to 5 times,
As shown in the front view of FIG. 6, the spotted pattern 7a...
produces walls with a whitish appearance.

The composition ratio suitable for obtaining the polished wall of the above-mentioned example was as follows.

It is preferable to mix 30 to 100 parts by weight of dolomite plaster with ±100 parts by weight of calcined diatom.

This is because if the amount is less than 30 parts by weight, it becomes difficult to harden and the strength decreases, whereas if it exceeds 100 parts by weight, it becomes too hard and tends to crack.

The carbon fiber content is preferably 1 to 5% by weight of the total weight of calcined diatomaceous earth and dolomite plaster; less than 1% by weight is ineffective, while more than 5% by weight makes polishing difficult. It is from.

Just add appropriate amounts of water and ingredients in advance.

In addition, carbon fibers have an average fiber length of 2 to 15
It is preferable to use a length of m, because if it is less than 2 seconds, the effect of preventing cracking is low, while if it exceeds 15 m, it becomes difficult to polish.

In the polished wall of the above example, due to the carbon fiber contained,
There are scales on the surface of the finished wall! ! It has the advantage of being able to create a beautiful appearance.

In particular, if you apply camellia oil to the surface of a polished wall after it has been finished and dried, it will create a blackish pattern depending on the amount applied, and this 8j pattern will also have a scale-like pattern, making it look even more beautiful. It has the advantage of being able to increase the

In addition, when the kneaded product of the above example and the kneaded product of the same composition as the conventional polishing Otsu were applied to the surface of a plywood board, the latter peeled off as it hardened, but the former did not peel off and adhered well. It was clear that in the case of the polished wall of the example of the present invention, it could be coated on various bases and its versatility could be improved.

The polished wall of the present invention is not limited to plastering applied to the base of a wall, but can also be applied to the surface of a mantel component, for example.
It can create a marble-like effect.

In addition, by applying it inside the formwork, polishing it, and removing the formwork,
It can also be used as a tile base material, and can also be applied to the surface of various base boards such as PC boards such as concrete boards and mortar boards, ALC boards, plywood, gypsum boards, and calcium silicate boards. Therefore, polished walls can be obtained not only by on-site construction but also by factory production. In addition, it can be applied not only to flat surfaces but also to curved surfaces, which are difficult to finish with conventional polishing methods.

The polished wall construction method according to the invention of claim No. (+) is as follows:
It also includes a method in which a material cut into a desired shape, such as a mountain or an animal, is attached to the surface of the base material, thereby making the surface of the base material uneven.

<Effects of the Invention> As is clear from the above explanation, according to the polished wall construction method according to the invention of claim 11, the strength of the wall can be increased and cracks caused by polishing work can be prevented by the action of carbon fibers. It is now possible to obtain polished walls at a low cost without requiring any skill in the polishing process.

In addition, because polishing can be achieved in a short time, even human plasterers can polish a wide range of areas while the plasterer is still in the uncured state, shortening the construction period and reducing construction costs. Became.

In addition, by simply polishing the surface of the base material by making the surface uneven, patterns can be created on the surface, and walls can be diversified not only by creating gloss, but also by creating patterns freely. It is now possible to obtain polished walls with patterns on their surfaces in a short time and at low cost without causing cracks.

Furthermore, according to the polished wall construction method according to the invention of claim (2), although the leaves of the plants themselves cannot be seen from the outside, the patterns of the leaves can be directly expressed. It is now possible to easily and naturally create leaf patterns of plants and trees without the hassle of creating leaf patterns using templates or the like.

In addition, according to the polished wall construction method according to the invention of claim (3), the pattern is created by forming unevenness on the base material itself. It is now possible to easily create patterns with desired shapes that are rich in color.
