Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a concrete wall structure constructed using a concrete block (for example, a retaining wall block) and a design structure of the concrete wall.

[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 in the concrete block itself. There are known stone wall designs and tile designs that are formed by forming a pattern.

[0003]

However, when a stone block design or the like is applied to a single concrete block, the range of the design is limited to the range of the concrete block. Therefore, if a concrete wall surface is formed while building this concrete block, the design will be interrupted in concrete block units. In other words, there is a problem that the design is divided by the inter-block joints and a continuous design cannot be expressed.

[0004] Even if a concrete block is provided with a stone wall design or the like by means of section raised portions, if the surface of the concrete block remains as it is, the surface becomes dirty or darkened due to weathering, aging, acid rain, etc. over time. Occurs,
In addition, there is a problem that appearance of the rainwater is partially deteriorated, for example, a trace of the flow of rainwater arrives.

The present invention has been made to solve the above-mentioned conventional problems. When a plurality of concrete blocks are constructed to form a concrete wall surface, the design is divided by seams between the blocks. Without
A first object is to provide a concrete block structure capable of expressing a continuous design. Also, in designing the concrete wall surface with partition raised parts, we focused on the surface dirt, which is a conventional problem, and on the contrary, we designed a concrete wall design structure that was able to apply design using this dirt. Second to provide
The challenge.

[0006]

In order to solve the first problem, a concrete wall structure according to the present invention (claim 1) is a concrete wall constructed by a plurality of concrete blocks, and each concrete block has a concrete wall surface. Is formed with a partition ridge sectioned by the joint groove, and at the end, a continuous flat portion is formed on the groove bottom surface of the joint groove, and this flat portion is connected between adjacent concrete blocks via a joint between blocks. It is formed so as to be continuous, and the raised panel member is attached to the continuous plane portion so as to cover joints between the blocks while maintaining a joint groove interval around the flat surface portion.

The concrete wall in this case includes a concrete wall constructed using a retaining wall block (such as an L-shaped block or a large stacking block), a brick block, or a slope block.

In such a concrete wall surface, a raised panel member is attached to a continuous plane portion so as to straddle an adjacent concrete block so as to cover a joint between blocks while maintaining an interval between joint grooves around the periphery.
As described above, since the raised panel member is attached to the flat portion, the raised panel member has the same appearance as that of the section raised portion formed in the concrete block, and the raised panel member has an adjacent concrete portion. Since the blocks are arranged across the blocks, the design is not divided by the joints between the blocks, and a continuous design by the section raised portions and the raised panel members can be expressed on the concrete wall surface.

In order to solve the second problem, the design structure of the concrete wall according to the present invention (claim 2) is:
Among all the raised sections including the raised panel members, the surface of some of the raised sections is formed on a soil-reducing surface obtained by performing a soil-reducing treatment on the concrete ground, and the surface of the other raised sections remains the same as the concrete ground. The structure was formed on the surface.

[0010] The stain-reducing surface is formed on the concrete surface by using a fungicide or a water repellent (for example, product name CONFIX SM-7 Tsunewa Chemical Industry Co., Ltd., product name Three Longie Z-50).
0 Cyan compound based on Three Bond Unicom Co., Ltd., and a transparent paint (for example, Dice Coat 6
00D (manufactured by Dainichi Seika Kogyo Co., Ltd.) is applied to prevent contamination by rainwater or dust. 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.

Further, in the design structure of the concrete wall according to the present invention (claim 3), the surface of a part of the protruding portions of all the protruding portions including the protruding panel members is a soil which is obtained by performing a stain-reducing treatment on the concrete ground. A coating that is formed on the suppression surface, a surface of some of the partition ridges of the other partition ridges is formed on the ground surface of the concrete ground, and the surface of the remaining partition ridges is painted with paint. Surface, a colored surface colored with a pigment, a frayed surface obtained by filing the concrete ground, and one or two or more types selected from a ground surface obtained by polishing the concrete ground. The configuration was adopted.

As described above, by forming a painted surface, a colored surface, a filed surface, and a polished surface in addition to the stain-reducing surface and the ground surface, the design pattern becomes wider and various designs can be expressed. it can.

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.
