Description

Description: TECHNICAL FIELD The present invention relates to a decorative construction method. More specifically, the present invention relates to a decorating method for arranging colored ceramic particles on the surface, and a molded product obtained by the method.

(Conventional technology and its problems) Conventionally, many concrete molded bodies and structures have a base material of concrete or mortar exposed on the surface as it is, and often impair the environmental aesthetics. However, in recent years, there has been an increasing demand for improving the aesthetics and landscapes of cities and the like, and tiles and paints on concrete secondary products and structures, regardless of the field of civil engineering and architecture, Alternatively, there is a tendency to change the concrete surface by exposing natural stones to the surface and to respond to the sense of a new age.

However, with traditional methods such as tiling and coating,
There were still some problems.

For example, when a tile is applied to the surface of concrete, there is no tar discoloration and the durability of the surface design such as concrete or mortar is improved.However, in this method, the ceramic tile is manually removed after the curing of the concrete is completed. It was necessary to stick the sheets one by one with an adhesive, which required a lot of labor and increased construction costs. Furthermore, the durability of the adhesive has also been a problem.

In the case of applying paint to the concrete surface,
Although it can be colored in various colors and has a feature of low construction cost, deterioration such as discoloration, expansion, peeling, etc. occurs over time due to ultraviolet rays, heat, alkali components in concrete, etc. However, there is a problem that the aesthetic appearance is significantly impaired.

The so-called washing method, in which natural stone is buried in the surface layer of concrete and the concrete on the surface is washed away until the natural stone is exposed and buried on the concrete surface, has been known so far, but it is characterized by utilizing the texture of natural stone. However, this method has a problem in that a large amount of sludge water generated by washing out the concrete surface has to be treated, so that it is difficult to perform on-site and the object is limited to secondary products.
Furthermore, since natural stone is used, there are restrictions on the types of colors.

In addition, a layer of a synthetic resin solution that can be used as an adhesive is thinly formed on the surface of the non-adhesive synthetic resin sheet by brushing or spraying, and a natural abrasion-resistant material made of natural stone, artificial stone, or the like is formed thereon. Sprinkle to form a member that is fixed to the layer of the synthetic resin solution in the form of dots or planes, place this member on the bottom of the mold, and mix the glass fiber as a reinforcing agent from above on a premix of cement. After curing and curing by pouring a slurry, etc., the non-adhesive synthetic resin sheet is peeled off, and a tile panel-like molded body in which a granular wear-resistant material is embedded on the surface and the material is exposed on the surface, and the same. A production method is known (JP-A-56-89505).
However, in such an adhesive state, the particulate abrasion-resistant material easily falls off from the sheet before being supplied to the next step, and if the dropped material is used as it is, the cement reaches the sheet surface. When the sheet is peeled off, the part where the particulate abrasion-resistant material has fallen exposes the cement, and the part where the particulate abrasion-resistant material is embedded and the part where the cement is exposed are exposed. As a product with certain unevenness and poor appearance, it has the disadvantage that unsatisfactory ones can be made, and even if it is a sheet in which the granular wear-resistant material has not fallen off, when the cement is poured, the cement becomes When the sheet is peeled off by reaching the point-like or planar bonding portion of the granular wear-resistant material and the adhesive and curing and curing, the granular resistant material is removed from the cement. In head to or cement and a flat condition exposed to punctate 耗性 material only exposed slightly,
It is completely buried in the cement,
At last, the granular wear-resistant material did not appear on the surface three-dimensionally, and had a defect that only an aesthetically inferior material could be obtained.

Further, as a pseudostone and a method for producing the same, an adhesive is applied onto a pattern, and a granular cosmetic such as natural stone or glass particles is mounted on the pattern with the adhesive, and the pattern is attached to a mold. Then, put the cement, cure and cure, peel off the pattern after demolding, or add the pattern in the mold, and then agar or konjac powder in the mold if necessary,
Inject a water-soluble coagulant such as starch, glue, and other water-soluble adhesives so that a part of the cosmetic material is exposed, pour cement after coagulation of the water-soluble coagulant, cure and cure. It is known that the pattern paper is peeled off after the mold, and then the coagulant is removed by washing with water to expose the decorative material on the surface (see JP-A-56-169189). However, in the case where the pattern is merely added to the mold, the cement is poured, the curing and curing are performed, and the pattern is simply peeled off after demolding, the same as that described in JP-A-56-89505 is used. On the other hand, when the cosmetic material is exposed from cement or the like, it is necessary to further inject a water-soluble coagulant in water, coagulate the coagulant, and wash the coagulant with water after demolding. Such a complicated and complicated time-consuming process as described above, and further, a post-treatment such as a wastewater treatment of water or the like in which a water-soluble coagulant after washing is dissolved, or a treatment of a sludge composed of a water-soluble coagulant or the like. It had the disadvantage of having to be done.

Because of these problems, various measures have been proposed to improve the aesthetics of concrete,
At present, a technology that has a durable color and is capable of decorating a concrete surface at low cost has not yet been realized.

An object of the present invention is to provide a low-cost decorative construction method that can solve the above-mentioned problems and can improve the aesthetics as well as the color durability.

(Means for Solving the Problems) In order to overcome the above-described problems, the present invention provides an adhesive layer having a thickness necessary for partially embedding colored ceramic particles on one surface of a sheet base material. After the colored ceramic particles are partially embedded in the adhesive layer to form a partially embedded sheet of colored ceramic particles, or at least one surface is sticky and has an elasticity necessary for partially embedding the colored ceramic particles. After partially embedding the colored ceramic particles on the one surface of the sheet to form a partially embedded sheet of colored ceramic particles, a cement or a mixture thereof is poured on the surface of the sheet, and after curing and curing, the sheet substrate is integrally peeled off with an adhesive. -To provide a decorating method characterized in that the colored ceramic particles are removed and inverted and buried in cement or a mixture thereof.

Another feature of the method of the present invention is that glass particles are used together with the colored ceramic particles.

Further, the present invention also provides a concrete or mortar formed body formed by the above method.

As the colored ceramic particles, there can be used those obtained by mixing clay and the like as a general ceramic raw material with a pigment, firing the mixture, coloring with a glaze, or particles having a specific hue as a ceramic. That is, natural and / or artificial ceramic particles can be used.

In this decorative construction method, the surface of the sheet on which the adhesive layer is formed is ceramics, and the particle size of the glass particles is 10 to
Ensure that 60% is buried.

As the sheet substrate in this case, for example, a sheet substrate made of paper, plastic, cloth, or the like is preferably used. An adhesive such as resin, rubber, or water glass is applied to the surface of these sheets so as to have a predetermined thickness, and the colored ceramic particles, and further, the glass particles are sprayed thereon in a predetermined arrangement pattern. This is partially sunk in the adhesive layer and partially buried in a predetermined amount. If at least one side of the sheet has a sticky surface and is highly elastic, the adhesive layer is not necessarily required. In any case, a predetermined amount of ceramic particles and the like are partially embedded.

If they are adhered in a dot-like manner without being buried, the problem is that ceramic particles fall off from the sheet base material, or ceramic particles are completely buried in concrete when inverted and buried in concrete. Occurs. In this state, decoration of the concrete surface cannot be performed, which is not preferable.

The shape of the ceramic particles and the glass particles can be appropriately selected from irregularities and smooth ones, but the former is more preferable.

For the sheet base material, by embedding a part of the multicolored ceramic particles and glass particles that have been subjected to hue patterning by patterning an adhesive, for example, casting concrete, mortar, cement, etc. in a fluid state on this surface,
By burying the film after curing, a surface with rich colors can be obtained. This makes it possible to significantly improve the beauty and the landscape.

Next, the present invention will be further described with reference to the accompanying drawings.

As shown in the process diagram of FIG. 1, in the method of the present invention, first, colored ceramic particles (2) are formed on a sheet substrate.
Is partially buried. At this time, an adhesive layer may be formed on the sheet substrate. In this way, the sheet (1) in which the colored ceramic particles (2) are partially embedded is adhered and fixed to the form (3). Next, concrete (4) or the like is cast into the formwork (3). At this time, the surface of the colored ceramic particles (2) protruding from the sheet surface is embedded in concrete (4) or the like, and as the solidified, the colored ceramic particles (2) become
Etc., so that it does not fall off. After curing,
The concrete (4) and the like are removed from the formwork (3), and then the sheet base material on the surface of the concrete (4) and the like are integrally peeled and removed together with the adhesive. The colored ceramic particles (2) remain in a predetermined color pattern on the surface of the concrete (4) or the like. In this way, the colored ceramics are embedded and fixed on the surface, and a colorful molded surface is obtained.

 Next, an embodiment of the present invention will be described.

(Example 1) An adhesive of water-soluble urethane rubber was applied to a 0.3 mm thick paper sheet surface so as to have a thickness of 2 mm, and colored ceramic particles were sprinkled thereon. About 30 to 50% of the particle size of the ceramic particles was embedded in an adhesive and solidified.

Next, a synthetic paste was applied to a surface on which the ceramic particles were not buried, and was adhered to a mold to assemble the mold. Thereafter, concrete was poured and poured, cured for 24 hours, and hardened.

After the concrete hardened, the mold was removed, and the sheet substrate on the concrete surface was peeled and removed together with the adhesive. About 50-70% of the ceramic particles on the concrete surface were embedded and fixed in the concrete. No ceramic particles fell off.

The resulting concrete product was extremely colorful and did not lose its aesthetic after one year.

(Example 2) An adhesive (PV) was attached to a cloth surface of a 300 mm x 300 mm, 1 mm thick cloth.
A) was applied so as to have a thickness of 1 mm, and three colored ceramic particles were scattered thereon to be solidified in various patterns. The back surface of the sheet was adhered to a 300 mm × 300 mm × 20 mm formwork using a double-sided tape.

After the resin mortar was injected into this mold, it was cured and cured for 24 hours. After curing, the mold was removed, and the sheet base material on the surface of the resin mortar was integrally peeled and removed together with the adhesive.
About 60 to 80% of the particle size of the ceramic particles was embedded in the resin mortar and was firmly fixed. The pattern formed on the sheet was transferred as it was, and a beautiful floor tile was obtained.

(Example 3) A water-soluble urethane rubber adhesive was applied to a sheet surface of polyethylene having a thickness of 0.2 mm so as to have a thickness of 1 mm, and blue ceramic particles were sprinkled thereon.
Ceramic particles were solidified by embedding about 50% of the particle size in an adhesive.

Next, the back surface of the sheet was adhered to a mold for a centrifugal force-formed CBS fume tube with a double-sided tape. Thereafter, concrete was poured into the formwork while applying a centrifugal force, and after molding, steam curing was performed to harden.

After curing, the mold was removed, and the sheet substrate on the concrete surface was integrally peeled and removed together with the adhesive. About 50 to 70% of the particle size of the ceramic particles was embedded and fixed in the concrete, and did not fall off at all.

The upper surface of the fume tube obtained in this example was decorated with durable blue ceramic particles.

(Example 4) A beevovar-based adhesive having a thickness of 0.8 mm was applied on a 0.5 mm-thick cloth sheet surface (300 x 300 mm), and dark blue ceramic particles were sprinkled thereon. The ceramic particles were cured by embedding about 40 to 50% of the particle diameter in an adhesive.

Next, the back surface of the sheet was adhered to a form having an inner size of 300 × 300 × 50 mm with a double-sided tape. Thereafter, about 10 mm of light blue colored cement was first poured into the formwork, leveled with a vibrator, and then 40 mm of concrete was cast, and the vibrator was again used to compact and compact.

After molding, the cement and concrete were allowed to harden, and the sheet substrate was integrally peeled and removed together with the adhesive.
About 50 to 60% of the ceramic particles were embedded and fixed.

No movement of the particles due to the vibrator was observed at all, and a concrete plate in which the ceramic particles uniformly dispersed in the light blue cement canvas were in excellent harmony was obtained.

(Example 5) A concrete flat plate was obtained in the same manner as in Example 4, except that pale yellow color cement was used as the cement.

 The colors were wonderfully harmonious.

Example 6 As shown in the sectional view and plan view of FIGS. 2 (a) and 2 (b), a hemispherical concave portion (inner diameter D =
10 mm) to a 0.4 mm thick vinyl chloride resin sheet (300 × 300 mm) (5), as shown in FIG. 3, via a synthetic rubber adhesive (6) as shown in FIG. 10 mm blue ceramic particles (7) were fixed in the recesses (8). Thereafter, the vinyl chloride resin sheet (5) side was fixed to a mold having an inner size of 300 × 300 × 60 mm with an adhesive. Concrete was poured into this formwork and spread with a vibrator. After the concrete was cured, it was released from the mold and the vinyl chloride sheet (5) was removed.

As a result, a beautiful concrete slab in which the blue ceramic particles were neatly arranged was obtained.

(Effect of the Invention) As described in detail above, the construction method of the present invention
Even after a long time, it does not fade and can maintain a colorful surface. It can improve the aesthetics and landscape of the city, and is much more economical than conventional methods.
