Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a concrete wall structure such as a block retaining wall constructed by using a retaining wall block or the like, a cast-in-place retaining wall constructed by cast-in-place, and other concrete structures.

[0002]

2. Description of the Related Art With respect to retaining wall blocks (L-shaped blocks, large pile blocks, and the like), partition ridges (for example, pseudo-stone-like ridges and tile-like ridges) defined by joint grooves are formed on the concrete wall surface itself. And the like, which are provided with a stone wall design or a tile design by forming a shape by molding. However, there is no one in which a partition ridge is formed by attaching a panel member.
In addition, even for concrete retaining walls and concrete structures constructed by casting in place, there are no concrete ridges formed by attaching panel members to the concrete wall surfaces.

[0003]

However, when such a section raised portion is formed by forming a mold, a mold for each design is required. Therefore, if the partition ridge is formed by attaching the panel member, the design by the partition ridge can be easily applied to the concrete wall surface. Further, when the concrete wall surface is constructed of concrete blocks, the area of the design is limited to the range of the concrete blocks in the case where the section raised portions are formed by molding in a conventional manner. Therefore, there is a problem that the design is divided at the joint between the adjacent concrete blocks, and a continuous design cannot be expressed.

[0004] Even if a concrete wall surface is designed with a raised section, if the surface remains the concrete surface, dirt and darkening occur on the surface due to weathering, aging, acid rain, etc. over time. In addition, there is a problem that appearance is deteriorated, for example, rainwater flow traces partially arrive.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems. When forming a partition ridge on a concrete wall, the partition ridge is formed by a panel member. It is an object of the present invention to provide a concrete wall structure that can easily form a partition ridge and that can be freely designed in an arrangement manner. In addition, when the concrete wall is constructed of concrete blocks, it is possible to express a continuous design without being divided by seams between the concrete blocks.
In addition, in designing a concrete wall surface with partition raised portions, attention is paid to surface dirt, which is a conventional problem, and conversely, design can be performed using this dirt.

[0006]

In order to solve the above-mentioned problems, a concrete wall structure according to the present invention (claim 1) is a concrete wall surface having a plurality of section raised portions defined by joint grooves. Thus, the partition raised portion is formed by holding the raised panel member around the joint groove while holding the joint groove.

[0007] In this case, the concrete wall surface such as a retaining wall block (L-shaped block or large stacking block), a brick wall, a concrete wall surface such as a block retaining wall constructed using a slope block, or a hollow block. Concrete wall surfaces such as block walls constructed using reinforced concrete, concrete wall surfaces such as retaining walls constructed by cast-in-place, and other concrete structures (piers and girders for elevated roads, concrete building structures, Quays, dams, etc.). In the concrete wall surface structure according to the present invention, the partition panel protrusion is formed and formed by attaching the raised panel member to the concrete wall while holding the joint groove around it. Therefore, the partition ridges can be easily formed, and the design can be freely designed in an arrangement manner.

In this concrete wall structure, there is a mode (claim 2) in which, when the concrete wall surface is constructed of concrete blocks, a raised panel member is attached to be straddled between adjacent concrete blocks. In this way, by mounting the raised panel member between adjacent concrete blocks, a continuous design can be expressed without the design being divided by the seams between the concrete blocks.

In this concrete wall structure,
The raised panel member includes a single raised panel member in which one partition raised portion is formed, and a composite raised panel member in which a plurality of partitioned raised portions partitioned while maintaining a joint interval are formed. There is an aspect (claim 3). in this way,
The use of a composite raised panel member allows a single raised panel member to form a plurality of section raised portions. In this case, if several types of composite raised panel members with different numbers and shapes of partition raised parts are prepared while keeping the overall outer shape the same, changing the design by partition raised parts can be achieved simply by changing them. Can be done.

In the concrete wall structure according to the first, second, and third aspects, the raised panel member is formed by molding, for example, iron flat stone (natural stone) into a predetermined shape in addition to the one formed of concrete. Can be used.

In the concrete wall surface structure of the present invention, the surface of a part of the partition ridges of all the partition ridges is formed on a soil-reducing surface obtained by treating the soil of a concrete ground, and the surface of another partition ridge is formed. Is formed on the ground surface of the concrete ground (claim 4). The stain-reducing surface is made of a cyanide-based agent such as a fungicide or a water repellent (trade name: CONFIX SM-7 Tsunewa Chemical Industry Co., Ltd., trade name Three Longie Z-500 Three Bond Unicom Co., Ltd.) ) And stains caused by rainwater or dust by applying a transparent paint (for example, Dice Coat 600D manufactured by Dainichi Seika Kogyo Co., Ltd.). Further, the ground surface is a surface of the concrete ground surface, which allows dirt. That is, in the long term, the background surface becomes dirty, and the stain suppression surface becomes hardly soiled, and the difference between the stains becomes a design. This is the basis of the design. Therefore, there is a difference in lightness between the stain-reducing surface, which is maintained as a concrete ground color due to the suppression of dirt, and the background surface, which has become dark due to dirt, and a design utilizing the contrast due to this difference in lightness. Can be expressed. In particular, on a rainy day, the ground surface absorbs the rain and turns dark, and the other stain suppression surface repels the rainwater and looks white, resulting in a large difference in brightness. Such a difference in brightness is a technical effect of the stain suppression surface, and it is possible to change the wall surface expression using natural force.

In this concrete wall structure,
Of all the raised sections, the surfaces of some of the raised sections are formed on the soil-reducing surface obtained by performing soil-reducing treatment on the concrete ground,
The surface of some of the other section ridges is formed on the ground surface of the concrete ground, and the surface of the other section ridges is painted with paint and colored with pigment. (1) A colored surface on which the surface of the concrete is applied, a filed surface of the concrete ground, and a polished surface obtained by polishing the surface of the concrete are formed on one or two or more selected surfaces. There is. Thus, in addition to the stain suppression surface and the ground surface, a painted surface, a colored surface,
By forming the filed surface and the polished surface, the design pattern becomes wider correspondingly, and various designs can be expressed.

As a coating process for forming the above-mentioned coated surface, a sealer is applied to the concrete ground, and then a coating material is applied from the sealer 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.
In addition, those in which the sealer is only applied to the concrete ground (the one in which the paint is not applied) are also included in the painted surface according to the present invention.

As a coloring treatment for forming a colored surface, a pigment dissolved in water is applied to the concrete ground, or a powdery pigment is applied to the concrete ground and then coated with a transparent clear (top coat) from above. A pigment that is impregnated with a pigment. 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.

[0015] In addition, as the filing process for forming a filing surface, mechanical filing processing in which a large number of needle bars attached to a hand-held type electric tool is used to strike a concrete ground, and high pressure water is applied to a wall surface by a water jet gun. Any of filing processing for jetting toward the surface and filing processing by sandblasting for jetting sand grains or metal grains may be used. The filet surface that has been filed in this way is roughened on the concrete surface, leaving aggregates and crushed stones exposed, as if cracking natural stone. In addition, since the concrete surface is roughened and the aggregate and the crushed stone are exposed on the chipping surface, the surface is easily stained by rainwater or dust. For this reason, if the filet surface is subjected to a stain suppression treatment by applying a water repellent or a fungicide, or if a transparent paint or the like is applied from above the filet surface, it is possible to suppress the filet surface contamination by rainwater and dust. it can. In addition, the degree of chipping is determined at a depth that does not affect the covering of the reinforcing bar.

The polished surface is obtained by polishing a concrete ground using a rotating grindstone or a rotating wire brush, and the polished portion becomes glossy and becomes black (dark gray) as compared with the portion where the concrete ground remains. It is in a so-called black state. In other words, unlike painted surfaces and colored surfaces, using this as a new design technology for concrete, while being concrete, natural stone is polished, expressing natural texture and improving aesthetics be able to. The polished surface may be subjected to a stain suppression treatment.
