DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a design structure for a retaining wall block used for constructing a concrete retaining wall.

[0002]

2. Description of the Related Art Conventionally, tiles and stone wall patterns are often provided on the wall surface of a retaining wall block. A state screen was formed.

[0003]

However, in the conventional retaining wall block, since the partition is defined by the mesh-shaped concave portions, the screen is more conspicuous than the mesh-shaped concave portions, and the design is mainly based on the surface. When designing blocks for retaining walls, there are various designs for concrete retaining walls, where the scenery of today is important, in addition to the conventional ones that are mainly made up of surfaces by mesh-shaped recesses. Should be.

The present invention differs from the prior art in that a mesh pattern (line pattern) is not made mainly of a surface but is made to be more prominent than a surface. The task is to provide a block design structure.

[0005]

In order to solve the above problems, a design structure of a retaining wall block according to the present invention (claim 1) has a plurality of sectional screens formed on a wall surface by a net-like convex portion. Configuration.

As described above, when a plurality of sectional screens are formed by the mesh-like convex portions, the mesh-like convex portions appear to stand out more than the sectional screens, and the outline of the sectional screen becomes clear due to the frame effect of the mesh-like convex portions. The net-like convex portions are emphasized, and a design mainly composed of a mesh pattern (line pattern) by the net-like convex portions can be expressed.

[0007] In this case, the outer surface of the net-like convex portion is formed on a stain-reducing ground net surface obtained by subjecting the concrete ground to a stain-reducing treatment (claim 2), and the outer surface of the net-like convex portion is colored. An aspect formed on a painted net surface (Claim 3)
There is.

[0008] When the outer surface of the net-like convex portion is formed on the soil-preventing ground surface or the painted surface, the mesh pattern can be made more conspicuous.

Further, in the present invention, the plurality of section screens are a stain-preventing ground section screen in which a soil treatment is performed on a concrete ground, a ground section screen in which the concrete base is left as it is, and a coating section in which paint is applied with paint. Any one or two types selected from a screen, a colored section screen in which the concrete ground is colored with a pigment, a cracked section screen in which the concrete ground has been sharpened, and a polishing section screen in which the concrete ground has been ground. There is an embodiment formed as described above.

[0010] In the stain suppression process for forming the stain suppression background net surface and the stain suppression background partition screen, a water repellent, a fungicide, and a transparent paint are applied on the concrete background.

As a coating process for forming a coating mesh surface and a coating area screen, a sealer is applied to the concrete ground, and then a paint is applied from above to form a coating film. As the paint in this case, a synthetic resin binder paint, a moisture-permeable paint, an aggregate-containing paint and the like can be used, and there is no particular limitation. The application of the paint can be performed by spray coating or brush coating using a spray device.

As a coloring treatment for forming a colored section screen, a pigment dissolved in water is applied to the concrete ground, or a powdery pigment is applied to the concrete ground, and then a transparent clear (top coat) is applied from above. What impregnates pigments by coating. Alternatively, concrete is molded by temporarily attaching a pigment, an aggregate, and a resin to the inner surface of a concrete form with an adhesive, and the pigment is impregnated into the concrete surface by transfer. In addition, there is a method in which a coloring agent, a coloring agent, and an accelerator are applied to the surface of concrete to cause a reaction, and coloring is performed.

[0013] In addition, in order to form a fuzzy area screen, fissing processing includes mechanical filing processing in which a large number of needle bars mounted on a handy type power tool are used to strike the ground of the concrete, and high pressure water from a water jet gun on the wall surface. Any of filing processing for jetting toward the surface and sandblasting for jetting sand grains or metal grains may be used.
In addition, since the concrete surface is roughened and the aggregates and crushed stones are exposed on this screen, the surface is easily stained by rainwater or dust. For this reason, if the screen of the filed section is subjected to a stain-reducing treatment by applying a water repellent or a fungicide, or if a transparent paint or the like is applied from above the screen of the filed section, the screen of the filed section is prevented from being stained by rainwater or dust. can do. In addition, the degree of chipping is determined at a depth that does not affect the covering of the reinforcing bar.

[0014] In addition, as a polishing process for forming a polishing zone screen, a concrete ground is polished using a rotating grindstone or a rotating wire brush. This polishing area screen
At the same time, the polished portion becomes glossy and becomes black (dark gray) as compared with the portion where the concrete ground remains, that is, a so-called black shiny state. The screen of the polishing zone may be subjected to a stain suppression treatment by applying a water repellent or a fungicide.

In the above aspect (claim 4), the design is applied to the section screen, and the design can be expressed in various patterns. In particular, when the section screen is formed of the stain-permissible background section screen and the background section screen, the design can be performed using the stain. That is, the concrete background is darkened by the dirt on the background area screen, and the darkening of the concrete background is suppressed on the other stain-permissible background area screen by suppressing the dirt. Therefore, it is possible to express a design using the brightness contrast. In addition, when the screen of the division section is formed, the screen of the division section is in a state where a natural stone is broken. Therefore, it is possible to express a natural texture and improve the aesthetic appearance even though it is concrete. Further, when the polishing section screen is formed, the polishing section screen becomes a blackish state, and the appearance can be improved.

[0016]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a perspective view showing a design structure of an L-shaped retaining wall block according to a first embodiment. In the following embodiments, the same components are denoted by the same reference numerals in the drawings.

The L-shaped retaining wall block 1 (retaining wall block) is formed into an L shape by a bottom plate portion 10 and a front plate portion 11, and the front surface of the front plate portion 11 is formed on a wall surface 12. A plurality of section screens 3 are formed on the wall surface 12 and partitioned by the net-like convex portions 2. In this case, the net-like convex portions 2 are formed so as to divide the three partition screens 3 in the upper part of the wall surface 12 and the two partition screens 3 in the lower part.

The cross-sectional shape of the net-like convex portion 2 is formed in a trapezoidal shape, and the top surface thereof is formed on a soil surface 2a obtained by subjecting a concrete surface to a soil-reducing process.

The section screen 3 is a stain-preventing background section screen 3a (shown by a dot pattern in the figure) obtained by applying a water-repellent agent or a fungicide to the concrete background and performing a stain-suppressing process, and the concrete background as it is. And the background area screen 3b.

Accordingly, in this design structure, since the plurality of sectional screens 3 are formed by the mesh-like convex portions 2, the mesh-like convex portions 2 appear to be raised more than the sectional screens 3, and the frame effect by the mesh-like convex portions 2 is achieved. Because the outline of the ward screen 3 becomes clear,
Conversely, the net-like convex portions 2 are emphasized, and a design mainly composed of a mesh pattern (line pattern) by the net-like convex portions 2 can be expressed. In addition, since the outer surface of the net-like convex portion 2 is formed on the soil suppression ground net surface 2a, darkening due to stain on the concrete ground can be suppressed, and the net-like convex portion 2 can be further conspicuous.

Further, since the section screen 3 is formed of the stain suppression background section screen 3a and the background section screen 3b, it is possible to design using the stain. That is, the background area screen 3b
, The concrete ground is darkened by dirt, and on the other stain suppression background area screen 3a, the darkening of the concrete ground is suppressed by the suppression of dirt, so that there is a difference in brightness between the two. Therefore, it is possible to express a design using the brightness contrast. Especially on rainy days,
The lightness difference between the background area screen 3b and the stain suppression background area screen 3a increases, and the wall surface becomes moist. It is possible to change the wall expression by the power of nature. The background area screen 3b sucks rain and turns black, and the stain suppression background area screen 3a repels rain and looks white. This brightness difference is the technical effect of the stain suppression background area screen 3a.

An example of a molding method for forming the net-like convex portion 2 on the wall surface 12 will be described with reference to FIG. First, a thermoplastic elastic material 60 that has been heated and dissolved to be in a liquid state is poured into the inside of the frame 5 installed on the wall surface model 4 and solidified to form the elastic mold member 6 (FIG. 2). -B). Next, concrete 7 for reinforcement is placed on the elastic mold member 6.
Is solidified (FIG. 2-B), and then the product model 4 is removed using the elasticity of the elastic mold member 6 to form the wall form 8 (FIG. 2-C). Then, the wall form 8 is incorporated into the L-shaped retaining wall forming form 9 (FIG. 2-D), and concrete is poured into the form and solidified. It is possible to mold the L-shaped retaining wall block 1 in which a plurality of partitioned screens 3 are formed.

Here, as the thermoplastic elastic material, for example, a polymer blend containing a high-molecular organic material and a low-molecular material as main components and having a lower content of the higher-molecular organic material than that of the low-molecular material is used. A high-molecular organic material having a three-dimensional continuous network skeleton structure is used (for details, see Japanese Patent Application Laid-Open No. 7-304965).
See the molding thermoplastic materials described in the publication).

FIG. 3 is a front view showing a design structure of an L-shaped retaining wall block according to a second embodiment. Also in the design structure of the L-shaped retaining wall block 1, a plurality of section screens 3 defined by the net-like convex portions 2 are formed on the wall surface 12. In this case, the section screen 3 is divided into a pseudo-stone shape, and the net-like convex portions 2 are formed so that the wall surface 12 has a stone wall pattern. Note that the top surface of the mesh-like convex portion 2 is formed as a colored mesh surface 2b.

The section screen 3 includes a stain-preventing background section screen 3a obtained by applying a soil-reducing treatment to the concrete ground, a ground section screen 3b with the concrete ground remaining, and a painting section screen 3c obtained by painting with paint. A colored section screen 3d in which the concrete ground is colored with a pigment, a cracked section screen 3e in which the concrete ground is sharpened, and a polishing section screen 3f in which the concrete ground is ground. Thus, the section screen 3 can be designed and expressed in various patterns.

Although the embodiment of the present invention has been described with reference to the drawings, the specific configuration is not limited to this. For example, as the retaining wall block, in addition to the L-shaped retaining wall block, a stacked block or a slope block may be used. The mesh shape of the net-shaped convex portion may be any pattern that can be expressed by a net, such as a triangular pattern, a square pattern, a polygonal pattern, a circular pattern, a stone wall pattern, and the like. Further, the width and height of the net-shaped convex portion can be determined appropriately, and the cross-sectional shape can be formed in a trapezoid, square, triangle, semicircle, or the like.
Further, the stain-preventing ground net surface or the painted net surface may be formed on the entire outer surface of the net-like convex portion or only on the top surface (part of the outer surface).

[0027]

As described above, in the design structure of the present invention (claim 1), since a plurality of sectional screens are formed by the mesh-like convex portions, the mesh-like convex portions are formed more than the sectional screens. In addition to the embossed appearance, the outline of the ward screen becomes clear due to the frame effect of the net-shaped projections, so that the net-shaped projections are emphasized conversely, and the design mainly consists of the mesh pattern (line pattern) by the net-shaped projections. Can be. In this case, the outer surface of the net-like convex portion is formed on a soil-controlling ground surface or a painted surface.
Or 3), the mesh pattern can be made more prominent.

In the design structure of the present invention (claim 4), the design is applied to the section screen, and the design can be expressed in various patterns. In particular,
When the ward screen is formed by the stain allowable background area screen and the background area screen, it is possible to apply a design using the stain.
