Further, partial recesses 16 for the tile or tile-like pattern 11 are formed at every other end of the tile or tile-like pattern 11 in the end portion, and the tiles or tile-like parts 11b separately prepared and By using the divided tiles or the tile-shaped parts 11a, it is possible to appropriately close the recessed portions 16 between the connecting members and in the row end members, and perform the installation without leaving the recessed portions 16 over the entire installation extension.

Further, FIG. 12 shows a case where the one according to the present invention is embodied as the waterway structure forming body 25, and FIGS.
Although it is an L-shaped member similar to that of FIG.
On the other hand, in the case of FIG. 12, an embedding of a natural stone material such as rubble or a pseudo rock pattern 13 is arranged on the inner surface thereof, and the natural stone or pseudo rock pattern used in the length direction of the waterway is formed on this. A waterway having a natural stone or pseudo rock wall is constructed by using the body 13b and the divided natural stone or pseudo rock pattern body 13a used at appropriate ends. It should be noted that it is well known that such a body 25 is used so as to face each other, and concrete is placed between the bar members 17 projecting at the tip of the bottom piece to form a water channel having a required width. .

While the body 25 of FIG. 12 is one in which two bodies are set to face each other to form a water channel, a section U is shown in FIG.
The shape of the integrally formed water channel component body 26 is shown, but the buried or three-dimensional pattern body of tiles or natural stones is arranged on the inner side surfaces on both sides of the water channel component body 26, and at each connection portion in the length direction of the water channel. By fitting and fixing tiles, natural stones, or a three-dimensional pattern plate-shaped body to the generated recesses 16, 16, it is possible to form a water channel having a continuous pattern on the inner surface.

Similar to FIG. 13, the one shown in FIG. 14 is an integrally formed water channel forming body 26 having a U-shaped cross section, and on one side of the inner surface thereof, the embedding of natural stone or the pseudo stone pattern 13 is adopted as a three-dimensional pattern body. And having natural stone or pseudo stone pattern 13 in which the inner surface of the waterway is continuous by fitting and fixing the natural stone or pseudo stone pattern body 13b to the recessed portions 16, 16 formed in the respective connecting portions in the length direction thereof. Becomes At the end of the water channel, the water channel component body 26
It is the same as the above-mentioned example that the natural stone or the divided pseudo-stone pattern 13a that is divided in half should be adopted in the recessed portion of the end portion. If passersby pass only on one side of the waterway, do not apply natural stones or three-dimensional pattern parts on both sides of the inner surface of the waterway. The object of the invention will be achieved.

In FIG. 15, natural stones such as rubble stones or pseudo-stone patterns 13 are provided on both inner surfaces of the water channel component 26 having a U-shaped cross section as shown in FIGS. 13 and 14, and a three-dimensional pattern portion is further formed on the bottom surface. Natural cobblestone or cobblestone body 12
In this case, the natural cobblestone or cobblestone-shaped body 12b formed as a separate body should be fitted and fixed to the recessed portion 16 formed in the connecting portion between the waterway component bodies 26. The same applies to the case where a cobblestone or cobblestone-shaped body 12a that has been divided is used at the water channel end.
By doing so, it is possible to give an appearance as if a water channel in a masonry state was formed over the entire inner surface of the concrete water channel, and it is possible to make it excellent in landscape.

FIG. 16 shows a case in which a tile is embedded in the inner surface of a water channel forming body 27 having a W-shaped cross section in which a flow path is divided into two, or a tile or tile-like body 11 is used as a three-dimensional pattern body. 1 shows an example of the present invention, in which a three-dimensional pattern is applied over the entire inner surface except the bottom of the water channel. At the connecting portion between the waterway component bodies 27, the tile or tile-shaped body 11b is fitted and fixed to the recessed portion 16 to form the waterway component body 27.
It is similar to each of the above-described examples that the connection relationship between the channels cannot be perceived.
It is also the same that the divided tiles or the tile-shaped body 11a should be fitted and fixed to the recessed portion 16 at the end of the water channel extension.

FIG. 17 shows the case where the embedding of a natural stone such as a quarry stone or the pseudo stone pattern 13 is adopted as a three-dimensional pattern only on the inner surface of the flow passage on one side of the water channel component 27 having a W-shaped cross section similar to FIG. The natural stone or pseudo-stone pattern 13b is formed in the concave portion 16 formed in the connecting portion of the waterway component body.
Should be fitted and fixed, and the concave portion 1 at the end of the water channel
It is the same that the divided pseudo stone pattern 13a should be fitted and fixed to 6 in the same manner. In a waterway using such a waterway structure 27 having a W-shaped cross section, it is necessary to give a three-dimensional pattern when the inner surface of the waterway is not exposed to human eyes by, for example, covering one side. It goes without saying that it is not necessary to understand that the present invention can be applied to appropriate portions (portions that are easily noticeable to the human eye) in various forms of waterway components.

FIG. 18 shows the L-shaped retaining wall material 10 shown in FIG. 1 according to the present invention when there is a step on the side opposite the roadway and the sidewalk surface.
A pedestrian road in which a green area is formed by the flat plate member 8 shown in FIG. 3, the pedestrian road boundary block 24 set at the road end shown in FIG. 8, and the front edge boundary block 25 shown in FIG. In the above example, although each unit body is formed by connecting the unit bodies having the three-dimensional pattern on the surface of the precast concrete material by adopting the above-mentioned constitution, the connection between the respective unit bodies The relationship cannot be discriminated, and the appearance can be made as if bricks were uniformly arranged along the entire sidewalk as shown in the figure. In addition, by lining the joints with color mortar etc. after installation, the appearance will be closer to that of on-site construction, and the joints and tiles, natural stones, and three-dimensional patterns will be distinguished to further emphasize continuity. .

Further, FIG. 19 shows the case where a waterway is formed at the end of a sidewalk, similarly to FIG. 18, each precast concrete material according to the present invention (see FIG.
18 is used to embed tiles on the inner surface or to form a tile-shaped body having a three-dimensional pattern. Others are the same as in the case of FIG. 18). This is an example of a sidewalk constructed as described above. When a pedestrian or the like walks on the sidewalk surface, the entire sidewalk area is formed by arranging brick materials or tiles evenly as in FIG. It will be.

FIG. 20 shows an example of a case where the plate material 8 shown in FIG. 4 is used to form a revetment block on a sloping ground such as a shore or a shore of a river. By inserting and fixing a cobblestone of natural stone or a cobblestone-shaped member 12b into the recessed portion 16 that is formed, the boundary portion between the plate materials 8 becomes invisible, giving the viewer an impression as if a natural cobblestone was spread. It is possible to maintain sufficient strength as a concrete revetment block while having an appearance that blends into the natural landscape of.

FIG. 21 shows the concrete material 9 shown in FIG.
Shows an example of the case where is adopted as a protection block for a relatively steep slope.
Despite being formed by connecting multiple units vertically and horizontally, it is still in a state where joints of the unit concrete materials 9 cannot be identified, and even if it is a precast concrete product, it is as if split on site. It has a high-class appearance with a stone-like appearance.

The embodiment of the present invention shown in FIGS. 18 to 21 described above is a prior art embodiment.
The effect can be understood more clearly by comparing with 9 to FIG. That is, the examples shown in FIGS. 29 to 31 are also those in which various tiles and natural stone materials are embedded or a three-dimensional pattern is applied to the product surface of the precast concrete as in the present invention. In any structure constructed by connecting multiple product units, the connection between each unit is obvious due to the presence of the joints, and any pattern on the surface will give a feeling of strangeness as a continuous structure. However, in contrast to FIG.
In the case of the embodiment according to the present invention shown in FIG. 21, the tiles, the natural stones, and the three-dimensional patterns formed on the surface are naturally continuous beyond the connecting portion of each precast concrete product unit, It is possible to create a high-quality finish without giving the viewer any discomfort.

[0035]

As described above, according to the present invention, although it is a product of precast concrete in which tiles or natural stones are embedded or a three-dimensional pattern is formed on an appropriate surface, they are continuously constructed as a structure. Even if the connecting parts of each precast concrete product are not identified by the viewer, it is possible to obtain the appearance as if the bricks, cobblestones, natural stones, rubble, etc. that appear as a three-dimensional pattern at the construction site were directly assembled. It is possible to make it comfortable with the surrounding landscape and to give it a high-quality finishing state, which is superior to the conventional technology and has a high industrial value. It is an invention.
