DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative concrete material for construction or civil engineering and to an improvement in a method for producing the same.

[0002]

2. Description of the Related Art Conventionally, there is a demand for a concrete material for construction or civil engineering that the construction front constructed with the material must be aesthetically pleasing, so that the surface of the concrete material exposed to the construction front is limited. It is a product that emphasizes the creation of a shape design on the surface so that it can be finished smoothly without any problems. In order to finish the construction front smoothly, a formwork was used, and the formwork surface was made smooth to finish the portion which becomes the construction front on the surface. Therefore, since the concrete casting portion of the formwork is an open surface, the concrete surface on this casting surface cannot be the construction front by construction. The reason is that even if you try to finish the surface smoothly using a mortar after placing the concrete, there is a drawback that the soft surface of the trowel always adheres clearly to the soft concrete surface, which impairs the appearance of the construction surface. It is. For example, building panels, L-shaped retaining walls for civil engineering, assembled vertical retaining walls, etc. are all included, and the concrete casting surface is the construction back surface and is constructed so as not to be seen by human eyes. In the case where a decorative concrete material is manufactured by subjecting a part to be a construction front of these concrete products (materials) to a decorative processing, the concrete material is manufactured by the above-described method, and a smooth finished construction front is obtained. After hardening and curing of the concrete, a coating material mixed with a coloring agent is sprayed and piled up by adjusting the diameter of the injection hole of the jet nozzle to form a concave and convex pattern on the surface and make up. Adopting a method of mixing and spraying colored ceramic powder in the paint, or simply applying a paint mixed with a colorant to the smooth surface portion to be the construction front and applying means .

[0003]

As described above, as long as the conventional method of manufacturing a concrete material is employed, there is a problem that the cast-in surface of the concrete cannot be used as a construction front part, and therefore, there is a problem. However, when producing a decorative concrete material, it is necessary to start the makeup process after the curing period of the concrete, so that a considerable time is required until the product is completed, which is inefficient. .
In addition, even if the surface is painted or the makeup is applied by overlaying the surface, there is a problem that the uneven painting by the flat painting or the overlay is recognized only as an artificial artificial face which is unnatural. It is increasing year by year that the peeling and the piled part are missing, and if only a part is painted or piled up to repair this, the decorative surface becomes more and more unnatural, so that the whole repair Therefore, there is an economic problem. In addition, in the coating with the ceramic powder, peeling and falling off always occur in the second or third year. When this method is applied to curbs of roads, the peeling of the coating is caused only by the contact of automobile tires. There is a disadvantage that. Also, the ceramic powder mixed paint has a problem that a high as ² per 4000 yen 6000 yen 1m also lacks economy. Therefore, the present invention is based on an idea completely reversed from the concept of the conventional method of manufacturing a decorative concrete material, that is, using a formwork in which a concrete casting surface is a construction front portion and using the formwork on the surface. Before the hardening of the concrete, the decorative material is applied and applied, and the decorative processing is performed. At the same time, a part of the cast concrete and the decorative material are mixed and integrated, and the peeling of the concrete and the decorative material is completed. In order to shorten the production period and simplify the manufacturing method and complete the reduction of material and material costs, the product is a stone material produced in the natural world. Such makeup is to enhance the value as a landscape material in a concrete material and to improve the product so that it can be supplied quickly at a low cost in large quantities.

SUMMARY OF THE INVENTION According to the present invention, there is provided a mold for manufacturing a decorative concrete material for construction or civil engineering, wherein a concrete casting surface is a construction front surface of the material. The concrete was cast on the frame, and then the decorative shape of the casting surface was adjusted according to the wishes of the construction site or the work owner, such as the combination of large and small irregularities or the combination of irregularities and grooves with wide and narrow grooves. The surface of the concrete casting surface is roughened so that the shape is not limited to the decorative shape and approaches the natural stone shape, and then a ground treatment material made of white cement, synthetic resin, or the like is sprayed over the entire surface of the roughened surface to form the material. A thin film is formed and coated, and the roughened surface is strengthened by combining the thin film so that the shape of the roughened surface is not collapsed as much as possible, and the base treatment material and the concrete material are mutually infiltrated and affinityd. A slightly hard mud-like cosmetic material such as resin None the cosmetic material appropriately biasing coating applied as a muddy mass of magnitude to the underlying treatment surface, concrete a part of the material - submerged bloom during preparative material when some simultaneously concrete -
Gently infiltrate the surface, partly leave the applied part in the state of remaining application, aiming for mutual infiltration and integration of the sinking part, the concrete material and the surface treatment material, and the sagging part, Next, the hardening and curing of the concrete is performed so that the concrete and the decorative material are integrated so as not to be peeled off, and then the mold is removed to produce a decorative concrete material with a decorative surface applied to the concrete. . Next, when the concrete casting surface is formed as a substantially flat decorative surface with little unevenness, the surface roughening step of the concrete casting surface is omitted, and a decorative material made of white cement, a synthetic resin, a coloring agent, etc. Means having an appropriate thickness and urging and sinking into a required pattern. In that case, the cosmetic material is partially sunk in the concrete, and the part and the cosmetic material spread on the concrete surface are mutually infiltrated and hardened and integrated. Same as the example. The undercoating material used was white cement, silica sand, a synthetic resin, a cement hardener, a pigment, and the like. The decorative material used was a slightly hard mud-like material prepared by adjusting the amount of the undercoating material. I do. By adopting the above-mentioned means, it is not necessary to finish a concrete surface to be subjected to decorative processing with a mold as in the prior art, and the above-mentioned problem can be solved very efficiently.

1 to 4 are explanatory views of the case where the present invention is applied to a building wall panel. Conventionally, since the building wall panel (A) is usually a flat plate, concrete is poured from the upper open surface of the formwork (2) so that the inner bottom surface of the formwork is finished as smooth as possible. It was used to face the front. That is, even if the cast surface of the concrete is smoothed later with a trowel, the back of the trowel cannot be used as a construction front. This is exactly the same for other architectural or civil engineering concrete products.
When this wall panel is used as a decorative wall panel, after the curing of the concrete is finished, the mold is removed, and a pattern is drawn on the smooth surface which is to be the front part of the construction, usually using a spraying means using a coloring mortar, paint, or the like. A decorative concrete material has been manufactured by forming a certain unevenness by embossing or the like and applying a pattern and a shape to the shape. In the present invention, the concrete casting surface (1) is immediately put into the concrete (3) in the formwork (2).
Is roughened using a roughened brush (4) or a roughened bokeh (5) as shown in FIGS. 7 and 8, for example. Immediately punches irregularities and grooves having different depths, widths or lengths. Next, a surface treatment material (6) prepared by appropriately mixing previously prepared white cement, silica sand, resin (mainly synthetic resin), cement hardening accelerator, and colorant (mainly pigment).
Is sprayed on the entire roughened surface to a thickness of about 1 mm to 2 mm by spraying or the like. It is needless to say that the degree of hardness and softness of the concrete to be used is adjusted by the assumed uneven decorative structure formed on the concrete casting surface. The same applies to the case where the amount and the like are adjusted according to the assumed makeup configuration (design). Next, when the above-mentioned undercoating treatment is performed, the undercoating treatment material (6) infiltrates with the roughened concrete mutually, and as a result, the roughened surface becomes white cement,
It is reinforced by silica sand, resin, etc., and the speed of collapse of irregularities and the like is suppressed or stopped in combination with the action of a hardening accelerator. In addition, the base color of the cosmetic assumed by the white cement or the pigment appears on the surface of the concrete integrally with the concrete. Immediately after the completion of the base treatment, white cement, silica sand, synthetic resin, concrete hardening accelerator, pigment (colorant) and the like prepared in advance are appropriately prepared and at least the base treatment material (6) is prepared. A more hard and muddy cosmetic (7)
Using a nozzle having a large or small nozzle diameter, the substrate is spray-coated on the base-treated surface by appropriately energizing it so as to have a previously assumed cosmetic design. It is a matter of course that several kinds of cosmetic materials having different colors are prepared and used in accordance with required patterns. At that time, the decorative material (7) in the form of a large or small mud-like mass becomes irregular on the roughened surface covered with the base material (6) and falls and scatters. In this case, it is a matter of course that the cosmetic material (7) may be applied to the base treated surface so as to have a required makeup state by using a brush or a hand together with the energizing application from the nozzle. What kind of design (shape or pattern) is to be applied to the makeup of the concrete material in terms of the degree of hardness and softness of the cosmetic material (7), the composition and arrangement of the colors, the amount of urging applied, the density of large and small lumps, etc. Of course, it may be appropriately adjusted as appropriate according to the purpose of use of the decorative concrete material, its use place, and the like. When the decorative material (7) is bias-applied on the roughened surface as described above, the decorative material (7) first forms large and small lumps on the base material (6) as shown in FIG. Land. When it lands on the decorative material (7), at that moment, the decorative material (7) is partially buried in the concrete due to its own weight and the force of spraying, and then the concrete and the base material (6) Some mixing and infiltration, and another part gently hanging around the coating part and mixing with concrete or the base material (6) by wet penetration (Fig. 4) It will be in the state of being applied. Further, the unevenness of the roughened surface formed on the concrete casting surface also has a certain degree of collapse of the peaks and corners because the concrete is not hardened, and is somewhat destroyed by the falling force of the decorative material (7) and its own weight. Further, in the urging coating, the energizing lowering coating is performed on a flat surface of the rough surface. Therefore, in the prior art, the uneven-shaped makeup is formed by applying (overlapping) mortar or paint on a smooth surface. However, in the present invention, "the surface is roughened and the decorative material (7) is applied to the surface. Sinking and the natural sagging phenomenon of the decorative material (7) and the mutual mutual infiltration and hardening of the concrete material and the base material (6) and the decorative material (7) associated therewith. The surface was formed. Immediately after the ground surface treatment of the roughened surface, the energizing coating of the decorative material (7) is performed,
At the same time as the partial burial, hanging, and infiltration mixing of the cosmetic material (7), the colorant flow phenomenon effect, the hardening of concrete, and the hardening effect of the base material (6) and the decorative material (7) also progress. This effect is also promoted by the curing accelerator mixed in the base material (6) and the decorative material (7). Therefore, the initial roughened surface of the roughened surface is somewhat distorted or rounded, but it can be said to be a natural phenomenon, as if the decorative surface was formed in the natural world in any way And a decorative concrete material that does not look like an artificially made decorative shape.

[0006]

FIG. 5 and FIG. 6 show a second embodiment in which the present invention is applied to a substantially planar building panel. -After the casting, the base treatment material (6) is sprayed first without forming a roughened surface on the surface, and then a required pattern or the like is formed while the decorative material (7) is applied by force. In that case, the decorative material (7) is partially sunk (declined) in the concrete and the base material (6), and the concrete, the base material (6) and the decorative material (7) are combined. Are infiltrated with each other in one part and are integrated and hardened.

[0007]

As described above, the decorative concrete material according to the present invention uses a formwork having a structure in which the concrete casting surface can be used as a construction front surface, and the makeup is applied to the concrete casting surface. Since it is formed, complicated techniques and materials or labor for forming the formwork or installing the formwork are required to finish the concrete casting surface as smoothly as this type of conventional concrete product. There is a great advantage that it does not. Next, the concrete
Since the casting surface is a release surface of the formwork, it is extremely easy to apply makeup on the surface. Also, since all makeup work is performed before the hardening of the cast concrete, the makeup pattern using a rough brush etc. on the cast concrete is used.
Not only is it easy to pierce (mainly shapes), but also the rough shape with an image that is very artificially initially observed is sprayed on the base material, energized coating of the decorative material, and part of it dive Natural phenomena, in which part of the base material and decorative material are infiltrated with the concrete and the concrete and the raw concrete, the natural phenomenon that irregularities on the roughened surface are broken down to some extent because it is raw concrete, and the flow phenomenon of colored pigments This has a very great effect that the roughened surface is formed like a shape and pattern formed in natural nature. Naturally, many aggregates are mixed in the concrete, and when it emerges on the surface of the roughened surface, the surrounding irregularities are somewhat collapsed and this aggregate part remains in a natural shape In addition, when the makeup is applied (applied) with a cosmetic material and a lump of the cosmetic material is applied to the periphery of the aggregate, the aggregate is lifted up and the makeup is applied. In addition to the effect of being formed, the use of the above formwork reduces the use of materials and equipment for the manufacture and installation of the formwork, ease of makeup work, low quality of makeup materials In addition, the present invention has an extremely large effect of dramatically improving productivity due to simplicity of demolding work on the formwork structure. Next, in addition to the embodiment as a decorative concrete material, L-type retaining wall, large-sized block, flat block, upholstery block, variable gutter, assembling vertical retaining wall, gutter cover, concrete floor board for civil engineering When these block materials are decorated with the makeup method of the present invention, the shapes and patterns of famous natural stones produced in various parts of the country can be applied to the above-mentioned concrete materials, which are called landscape materials and the industry. It also has a great effect that it can be easily expressed. Next, as described in the embodiment, the concrete
Part of the base material, the base treatment material and the decorative material are swelled and hardened together, so that even if the decorative material has aged, it has the effect that it does not fall off from the concrete material and is swellable. Accordingly, the primary color of the colorant is blurred in a certain portion and also appears as a flowing pattern of natural stones, which is more viewed as a natural stone, and has an effect that there is no substitute for a landscape material. Of course, there is also an advantage that the expression of the decorative pattern can be freely determined because the colorant (eg, pigment) can be freely used and blended. Also bid decorative material natural, in the case of the ceramic powder used is 200 yen to about 300 yen in Although the present invention 1 m ² unit price is 4000 yen to 6000 yen, and introduction of technology from the United States (US Max Ton Inc. for) material is also expensive as 1 m ² unit price 3000 yen to 4000 yen, there is an advantage that very low Ren if Hisure thereto.
