Abstract

PROBLEM TO BE SOLVED: To improve aesthetic appreciation of a design by forming an imitation- stonelike irregular colored surface out of a painted surface and a non-painted surface, and forming the fitting surface of a design panel into a concrete exposed surface in a state of concrete skin. SOLUTION: An L-shaped retaining wall block A is formed with a bottom plate part 10 and a rising part 11 into a L-shape. The front of the rising part 11 is formed into a concrete wall face 12 to be designed. The concrete wall face 12 is formed with a painted surface 12a and a non-painted surface 12b as an imitation-stonelike irregular colored surface. Further, it is formed into the fitting face 12c of a design panel 2. For fitting the design panel 2 to the concrete fitting face 12c, insert nuts are buried in the fitting face 12c, and bolts are fastened with the insert nuts through bolt holes formed on the design panel 2. Consequently, compared it with a construction designed by colored painting alone, aesthetic appreciation of this design can be improved by combination of the non-painted surface with the design panel.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a design structure by a coloring method for a concrete retaining wall constructed for earth retaining.

[0002]

2. Description of the Related Art Conventionally, when a design is applied to the wall surface of a concrete retaining wall by colored coating, a patent application no.
As disclosed in No. 1475, the present applicant has filed an application for a design structure in which a colored painted surface and a mounting surface of a design panel are formed on a wall surface, and the mounting surface of the design panel is an unpainted surface.

[0003]

However, as for the concrete retaining wall, since the back surface is in contact with the soil containing moisture, not only breathing from the back surface becomes difficult, but also moisture and moisture from the back surface become difficult. Impregnated and penetrates into concrete.

[0004] The water or moisture tends to be discharged from the concrete wall as water vapor to the outside. At this time, if the concrete wall is entirely colored, it is blocked by the coating film and the water is removed. And moisture cannot be discharged. In this case, breathing from the concrete wall surface is hindered, and the paint is pushed up from the back by moisture or moisture, and a problem arises in that the painted surface rises to cause peeling of the paint.

[0005] In addition, cracks often occur in concrete retaining walls during manufacturing or at an early stage of manufacturing, and even after installation on the site, cracks occur due to load. This is theoretically obvious from the viewpoint of reinforced concrete engineering.

[0006] The idea that a crack is taken for granted is no exception for concrete retaining walls. This hinders the coloring of the concrete retaining wall. In the conventional colored coating, the coating is lifted by moisture or moisture due to cracks, and causes the coating to peel off.

In particular, on a concrete surface whose wall surface is partitioned into a large number of pseudo-stone-like uneven surfaces, the joints have numerous cracks. If you paint on this, the paint will come off from the joint cracks after about 3 years and 4 years.

The reason that cracks occur in joints is likely to occur because the joints are sandwiched between pseudo-stone-like uneven surfaces and have a narrow width. In addition, at the time of placing concrete, cracks occur at the stage of concrete that has not been solidified yet due to unstable conditions such as aggregates such as crushed stones, vibration (re-vibration fine), breathing, and the like. Of the entire retaining wall, cracks are most likely to occur at joints.

A particularly troublesome problem with the pseudo-stone-like irregular surface of concrete is that many bubbles are generated on the surface. When a conventional waterproof resin binder paint is applied over the air bubbles, the air bubbles are closed by the coating film to form voids, and water is accumulated therein, resulting in breaking the coating film.

[0011] The above-mentioned Patent Application No. 191475 is also an invention for solving the same problem, but requires a technique capable of discharging moisture even more sufficiently.

The present invention has been made in order to solve the conventional problems such as the above-mentioned technique, and when applying a design (pattern) to a concrete wall surface, a pseudo-stone-like uneven colored surface is defined as a painted surface and an unpainted surface. Focusing on combining these with design panels, this not only enhances the aesthetics of the design, but also maintains the breathing of concrete and eliminates paint peeling caused by water and moisture. It is an object of the present invention to provide a design structure of a concrete retaining wall that can be used.

[0013]

In order to solve the above-mentioned problems, a design structure of a concrete retaining wall according to the present invention is characterized in that a pseudo-stone-like uneven colored surface is formed by a painted surface and an unpainted surface. The mounting surface is formed on the exposed surface of the concrete with the concrete ground.

In this case, in the design structure of the concrete retaining wall according to the first aspect, there is an embodiment in which the painted surface of the pseudo-stone-like uneven colored surface has moisture permeability.

The design structure of the present invention is to design a concrete wall surface by combining the colors of the painted and non-painted surfaces and the design panel. Performance can be improved.

In particular, the non-painted surface is provided on the pseudo-stone-shaped uneven colored surface, and the mounting surface of the design panel is provided. In other words, the first is that the painted surface of the pseudo-stone-shaped uneven colored surface is not painted, and the painted surface of the pseudo-stone-shaped uneven colored surface is reduced, in addition to the combination of colors. There is to let. Therefore, moisture and moisture in the concrete are converted to water vapor and discharged to the outside from the unpainted surface.

Another meaning is that breathing can be maintained from the mounting surface. This mounting surface is formed by notching the pseudo-stone-shaped uneven colored surface in a flat shape so that the design panel can be accommodated. The depth of the notch corresponds to the joint corresponding to the pseudo-stone-like uneven colored surface. Therefore, moisture and the like can be discharged to the outside from the mounting surface at a position deeper than the non-painted surface. As described above, the mounting surface can be used as a surface of a picture by a design panel while securing the mounting surface as an exhaust surface for moisture or the like.

In addition, directly on the concrete of the mounting surface,
When trying to express a pattern by colored painting, the production of the pattern is complicated because the expression is intricate, because of the large number of colors, overpainting, etc., due to problems such as paint curing, weather, temperature, etc. Extremely bad. You'll spend hours on one picture. Adding a design directly to concrete means that you have to work outdoors and directly depend on the weather. Rain during work is not forgiven. In contrast, using design panels is lightweight, so you can work indoors without being affected by weather or temperature.
You can work efficiently. In this way, the purpose of using the design panel is to facilitate the work of painting a pattern and to secure a surface for discharging moisture and the like.

[0019]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is an exploded perspective view showing a design structure of an L-shaped retaining wall block A according to a first embodiment. FIG. 2 is a sectional view including a mounting surface.

The L-shaped retaining wall block A is formed in an L-shape by a bottom plate portion 10 and a rising portion 11, and a front surface of the rising portion 11 is formed on a concrete wall surface 12 on which a design is made.
On the concrete wall surface 12, there are formed painted surfaces 12a, 12a (gray and reddish brown in the figure) and non-painted surfaces 12b (shown in white in the figure) as pseudo-stone-like uneven colored surfaces,
Further, a mounting surface 12c of the design panel 2 is formed.

The painted surface 12a is colored with a paint, and is colored in two types of red-brown and gray syringe stones in design. In addition, this coloring painting,
This is performed by spray coating using a spray device. As a paint in this case, mix emery sand with cement,
A paint that is commonly called a ceramic paint containing an acrylic emulsion is used. Unpainted surface 12b
First, apply a colorant on the uneven surface of the artificial stone,
Next, a color former and finally an accelerator are applied. Incidentally, the accelerator is for accelerating a chemical reaction for producing a color. The color is light green (shown in white in the figure).

The mounting surface 12c is formed by notching a pseudo-stone-like uneven surface in a plane so that a design panel can be accommodated. The depth of the notch is a portion corresponding to a joint surrounding the pseudo-stone-like uneven surface. The design panel 2 is replaceably mounted on the mounting surface 12c while keeping the concrete ground surface.

The design panel 2 is formed on a design surface 21 by a PVC sheet having a pattern drawn on an acrylic plate as a panel member by ink jet. The design surface 21 in this case is obtained by bonding an acrylic plate and a PVC sheet.

The design panel 2 is mounted on the concrete mounting surface 12c by the mounting surface 12c.
The insert nut is buried in c, and the insert nut is replaced with a bolt through a bolt hole formed in the design panel 2.

The design panel 2 may have design surfaces 21 and 21 on both the front and back surfaces. In this case, for example, when it is necessary to replace the design with the passage of time after the front panel is mounted so that the front side becomes the outer side, the design panel 2 is turned upside down so that the back side becomes the outer side. Has the advantage that one design panel 2 can be used twice.

Therefore, in the L-shaped retaining wall block A, the painted surface 12a, the unpainted surface 12b, the mounting surface 12c,
Are combined to design the concrete wall surface 12, so that the aesthetics of the design can be improved by the combination of the light green non-painted surface 12b and the design panel 2 as compared with the one designed solely by colored painting.

The effect of the unpainted surface 12b is not only to balance the color with the painted surface 12a, but also to discharge moisture in the concrete from the unpainted surface 12b. If the pseudo-stone-like uneven colored surface is entirely covered with the painted surface 12a, moisture cannot be discharged, and
a leads to peeling of the coating. Even if cracks or bubbles are generated in the non-painted surface 12b, since the non-painted surface 12b has no coating film, moisture or moisture in the cracks or bubbles becomes water vapor from the unpainted surface 12b and goes out. .

The mounting surface 12c of the design panel 2
Since this is a concrete ground, this portion is not covered with the coating film. Therefore, breathing can be maintained from the mounting surface 12c. The position of the mounting surface 12c is the same as the distance T1 from the back surface of the rising portion 11 to the joint, as shown in FIG. 2, and is T2. Since it is shorter than the distance T3 from the back surface of the rising portion 11 to the surface of the pseudo stone uneven surface,
Moisture inside the concrete concentrates on the mounting surface 12c and is discharged therefrom. For example, the difference between T2 and T3 is 5
cm. Thereafter, a path for air and water is gradually formed toward the mounting surface 12c, so that the user concentrates on the mounting surface 12c as if invited, and promotes the discharge of moisture. The thickness of T2 is necessary for structural calculation,
The thickness is necessary to give the impression of the rough surface of the pseudo stone. Since the panel is noticed at that position, moisture and moisture can be discharged with priority over any wall surface 12.

In this way, two outlets for moisture and moisture are formed on the concrete wall surface 12 such as the unpainted surface 12b and the mounting surface 12c, and the moisture and the like near the surface of the painted surface 12a are removed from the unpainted surface 12b. The cause discharged from the mounting surface 12c, which causes the coating film on the painted surface 12a to bulge and can be removed.

Next, FIG. 3 is a front view showing a design structure of an L-shaped retaining wall block B according to a second embodiment. In the L-shaped retaining wall block B, the upper surface of the concrete wall 12 has a painted surface 12a and the middle portion has a design panel 2a.
Mounting surface 12c, and a non-painted surface 12b in the lower part,
Are formed. In addition, root entry part 15 below the lower part
Is in a soil-covered position and remains on the concrete ground.

The L-shaped retaining wall block B has a mounting surface 1
It is characterized in that the 2c and the unpainted surface 12b are arranged in the middle and lower stages of the concrete wall surface 12. That is, the water and moisture inside the concrete are higher in the lower tier than in the upper tier, depending on the height of the soil behind the L-shaped retaining wall block B, and exist as long as they are not discharged outside. For this, the painted surface 12a
Is arranged at the lower stage, there is a possibility that the coating film may be blistered. Therefore, in the L-shaped retaining wall block B, since the painted surface 12a is disposed on the upper stage of the concrete wall surface 12 with low humidity, the peeling of the painted surface is the safest side.

Painted surface 12a as a pseudo-stone-like uneven colored surface
(Shown in black and gray in the figure) is colored with a paint having moisture permeability. Examples of the paint in this case include a trade name of Loan Coat (manufactured by Dainichi Seika Kogyo), a trade name of Dice Coat (manufactured by Dainichi Seika Kogyo), a trade name of Sandy Face (manufactured by Dainichi Seika Kogyo), and a trade name of Mukitex. (Shinto Paint Co., Ltd.) can be used to obtain high moisture permeability. In order to enhance the moisture permeability including the above-mentioned paint, any paint can be used as long as it can contain silica sand, emery sand, or the like and can adjust moisture permeability appropriately. For example, in the lawn coat and the die coat, the moisture permeability (JISZ0208) can be adjusted in an area of 130 g to 1000 g / 1 square meter / day by mixing with silica sand. The minimum value of the moisture permeability is 130 g, and below this, the effect of the moisture permeability does not appear.

Painted surface 1 made of paint having moisture permeability
2a has a feature that the moisture and moisture in the concrete are discharged to the outside, so near the surface of the painted surface 12a,
No cracks, no air bubbles, no bubbles. Therefore, the coating film does not swell. The painted surface 12a is shown in FIG.
It is shown in two types, black and gray.

The mounting surface 12c of the design panel 2 in the middle part is formed on the exposed surface of the concrete that is not covered with the colored paint by the paint, and the design panel can be replaced on this mounting surface 12c (bolt fastening). Attached to.

The design panel is made of a veneer panel generally called a control panel as a panel member, which is waterproofed with urethane resin on both front and back sides, and on which a design surface with a pattern is formed by paint. . The design is also different on both sides.

The lower part of the unpainted surface 12b (shown in white in the figure) is obtained by applying the technology of TYK (penetrating colored material-treated decorative form, manufactured by Toyoko Giken Co., Ltd.). A color pigment, an aggregate, and an adhesive are mixed, and the mixture is attached to the corresponding mold portion of the non-painted surface 12b of the pseudo-stone uneven surface. After that, when the concrete is cast, it is integrated with nature, and when the concrete hardens, the unpainted surface 12b is formed.

On the unpainted surface 12b, a natural stone-like pattern is formed, and since it is not painted, there is no coating film, and concrete can be freely breathed. In particular, it is located at the lower part of the L-shaped retaining wall block B, and is the location with the highest moisture and humidity on the wall surface.
The reason why the non-painted surface 12b is formed on this portion is to avoid forming a coating film on the lower portion. Together with the middle mounting surface 12c, the concrete has a sufficient breathing ability. This L-shaped retaining wall block B
When the height is 3 m or more, the effect is enhanced.

Next, FIG. 4 is a front view showing a design structure of a cast-in-place retaining wall C according to a third embodiment. In the in-situ retaining wall C, a group of non-painted surfaces 12b of pseudo-stone-like irregular surfaces is formed so as to surround the group of painted surfaces 12a of pseudo-stone-like irregular surfaces of the concrete wall surface 12. The mounting surfaces 12c of the design panel 2 are formed at intervals.

The feature of the third embodiment is that the painted surface 12a is solid and the periphery thereof is surrounded by the unpainted surface 12b. Therefore, even if moisture or moisture remains on the concrete wall surface 12 in the group of the painted surfaces 12a, the surrounding uncoated surfaces 12b become steam and are discharged. Therefore, the paint on the group of painted surfaces 12a does not come off. The painted surface 12a is finished in a lizard-like mixture of three colors of waterproof paint.

Next, FIG. 5 is a front view showing a design structure of an L-shaped retaining wall block D according to a fourth embodiment. In the L-shaped retaining wall block D, a painted surface 12a and a non-painted surface 12b of the pseudo-stone-like uneven colored surface of the concrete wall surface 12 are formed, and two mounting surfaces 12c of the design panel 2 are formed.

The feature of the fourth embodiment is that two attachment surfaces 12c of the design panel 2 are formed on the concrete wall surface 12, thereby diversifying the expression by the design panel 2, and the moisture and moisture from the attachment surfaces 12c, 12c. To promote emissions.

FIG. 6 is a front view showing a design structure of an L-shaped retaining wall block E according to a fifth embodiment. In this L-shaped retaining wall block E, the lowermost root portion 15 of the concrete wall surface 12 remains covered with the soil because the soil covers it. Depending on the height of the retaining wall, there are cases where the height is about 50 cm. The mounting surface 12c of the design panel 2 is provided on the upper stage, and the painted surface 12a and the non-painted surface 12b are further formed on the upper surface.

The feature of the fifth embodiment is that a mounting surface 12c is formed below the concrete wall surface 12. With this arrangement, the upper painted surface 12a and the lower non-painted surface 12b balance the color and form a non-painted surface over the lower part of the wall surface 12 where moisture is concentrated, so that the discharge of moisture and moisture is sufficient. it can.

The painted surface 12a is provided with a white skin and a black skin, respectively. As the paint, a dice coat is used as a moisture-permeable paint. Unpainted surface 12
In b, greenish blue and light green coloring are formed in the order of the colorant, the color former, and the accelerator.

Although the embodiments of the present invention have been described with reference to the drawings, the specific structure is not limited to the embodiments. For example, the painted surface can be a simple one,
A solid color may be used, or a flower pattern or the like may be expressed using the base as a base. This design structure is applicable not only to the L-shaped retaining wall block and the cast-in-place retaining wall described in the embodiment, but also to wall-type anchor retaining walls such as Tail Arme, trade names, and upright type building blocks such as GOLDCON. It may be. Further, there is no limitation on the shape of the pseudo-stone-shaped uneven surface. For example, as shown in FIG.
(An interval of about 0 cm).

As the pseudo-stone-like uneven surface, a shape having a brick-like shape as shown in FIG. As the paint, a paint having moisture permeability is desirable, but a waterproof paint may be used. Further, as the color used for the non-painted surface, two or more colors that are in harmony with the painted surface may be employed.

Further, the design panel member is not limited to a plastic plate or a veneer plate, but may be an iron plate, a cement plate or the like. If the combined area of the non-painted surface and the mounting surface of the design panel in the wall surface of the concrete retaining wall is 12 to 20% or more of the entire wall surface, sufficient discharge of moisture and moisture can be obtained.

[0048]

As described above, in the design structure of the concrete retaining wall of the present invention, the pseudo-stone-like uneven colored surface is composed of a painted surface and an unpainted surface, and the concrete wall surface is formed by combining these with the design panel. The design aesthetics can be improved by the combination of the unpainted surface and the design panel, compared to a design that uses only colored paint.

Further, since the unpainted surface and the design panel mounting surface are unpainted surfaces (ground), the entire surface of the concrete wall is not covered with the paint film, and breathing can be maintained from both surfaces. Can discharge moisture and moisture. If it is considered that the painted surface area is large, it is possible to adjust the area such as increasing the non-painted surface, and it is also possible to appropriately arrange the non-painted surface and the painted surface. In particular, when a paint having moisture permeability is used for the painted surface, the effect of discharging moisture and moisture is further enhanced. This has the effect of preventing the problem of peeling of the coating that occurs on the coating surface.

The term "non-painted surface" as used herein refers to a surface which is not painted, that is, colored by a method other than coating, although the pseudo-stone-like uneven surface is colored. Since moisture cannot be discharged to the outside in the coating film, a colored surface that can be discharged is formed. As a method, a colorant is applied to an uneven surface, and a color former and an accelerator are overlaid thereon, a TYK (penetration coloring material-treated cosmetic form, manufactured by Toyoko Gijutsu) technical application, a coloring method by impregnation, There is a method in which a pigment, an aggregate, and an adhesive are pasted on a sheet in advance, which is attached to a mold, and concrete is poured and colored. Anyway, any technology can be used as long as the water and moisture inside the concrete can be discharged to the outside and a colored surface is formed.
