Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a concrete imitation such as a pseudo stone or a pseudo tree that is mainly disposed in a building exterior, a garden, a park, a street, an amusement park, or the like.
[0002]
[Prior art]
Conventionally, the thing made from a concrete or a plastic is known as an artificial tree or an artificial stone. For example, in Japanese Patent Application Laid-Open No. 2001-300912, a fluidized layer of a plurality of colored release agents having different colors is formed on the inner surface of a mold, and colored concrete mixed with a pigment is poured into the mold and cast. Artificial stones have been proposed. Japanese Patent Application Laid-Open No. 8-230398 discloses that a surface layer portion is formed of a synthetic resin mixed with wood flour, an uneven grain pattern is formed on the surface of the surface layer portion, and the surface of the surface layer portion is baked and burnt. A pseudo tree with a grilled cedar pattern on the surface has been proposed.
[0003]
[Problems to be solved by the invention]
However, as described above, in the pseudo stone formed by forming a fluidized layer of a plurality of colored release agents having different colors on the inner surface of the mold and pouring colored concrete mixed with a pigment inside the mold, However, it is unnatural because it does not match the surface of the stone surface, and by adding a pigment to the material to be poured, the hue can be further widened. When the material to be produced is used, there is a problem that the molded product does not have a protective layer and is easily whitened and has poor durability. The surface layer was formed from a synthetic resin blended with wood flour, an uneven grain pattern was formed on the surface of the surface layer, the surface of the surface layer was burnt and burnt, and a cedar pattern was formed on the surface In artificial trees, it is suitable for materials with convex parts that are different from the base material, such as baked cedar, but it is difficult to simulate materials that have dirty concave parts due to moss, straw, etc. It was.
[0004]
Therefore, as a result of earnest research in light of the conventional drawbacks, the present inventor provides a method for creating a natural material-like mimic that can reproduce the texture of a decayed old wood and the stone surface whose surface convex portions are flattened due to wear. is there.
[0005]

DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described below with reference to the drawings.
FIG. 1 is a cross-sectional view showing an example of an embodiment of the natural material-like mimic of the present invention.
In the figure, a concave portion 12 and a convex portion 13 are formed on the surface of the base material 11 so that the surface of the natural material such as wood or stone is simulated. A sealer is applied to the surface of the substrate 11, and a first coating layer 14 and a second coating layer 15 are formed on the surface of the sealer layer 16. The second coating layer 15 is formed by applying a coating on the first coating layer 14 and wiping off the portion of the coating excluding the recess 12 with a waste cloth before drying and curing.
[0010]
Next, an example of how to make the natural material-like mimic of the present invention will be described with reference to FIG.
In the figure, reference numeral 2 denotes a wood block, and an example in which the concrete pseudo tree 1 is made using this wood block as a matrix will be described. A wood block obtained by cutting a tree into a rectangle is used, but if a decayed old tree is used, it becomes a pseudo tree with an antique texture, which is preferable.
[0011]
An outer mold frame in which the plate-like body 3 is disposed on the bottom and the four side surfaces is provided, and the wooden block described above is disposed in contact with the bottom surface in the outer mold frame, and silicon rubber, urethane rubber, etc. are disposed in the outer mold frame. A two-component curable elastomer 4 is injected. After curing, the elastomer 4 is taken out from the outer mold, cut and divided with a cutter such as a knife, and the wooden block is taken out to form a mold 5.
[0012]
If the dividing surfaces of the formwork 5 are matched, concrete is poured from the bottom, and the concrete is hardened, the formwork 5 is divided to obtain a base material 11 having an old wood bark formed on the surface. After confirming that the surface of the substrate 11 is dry, deposits on the surface such as dirt are removed, and a sealer such as an aqueous sealer or a solvent sealer is uniformly applied to the surface of the substrate 11 to seal the sealer. Layer 16 is formed. After drying the applied sealer, a paint is applied onto the sealer layer 16 and dried to form the first coating layer 14. If a paint having a color different from that of the first paint film is applied onto the first paint film layer 14 and the entire paint is wiped off with a waste cloth or the like while the paint is not dried, the paint tends to remain in the recesses 12. Then, the second coating layer 15 is formed by imprinting the coating material in the recess 12 and then drying it. If the first coating layer 14 and the second coating layer 15 are thus formed, the colors of the concave portion 12 and other portions (convex portions) are different, and the texture of the natural material is created. The sealer in this example adjusts the suction of the coating material constituting the first coating layer 14 and the second coating layer 15 into the base material 11, improves the adhesion strength of the coating material, reinforces the surface layer of the base material 11, This is suitable for preventing leaching of an alkaline substance from the material 11.
[0013]
The above-mentioned concrete may be ordinary concrete, but if the pigment is kneaded with a composition that gives a color tone similar to that of the first coating layer 14, the first coating layer 14 is broken and the base material 11 becomes There is no sense of incongruity when exposed. In addition, if a transparent sealer is used, the hue of the base material 11 can be changed to the first coating film to form a mimic. In addition, as the paint used in the present invention, a synthetic resin emulsion paint is preferably used. As a synthetic resin constituting the paint, a synthetic resin such as an acrylic resin, a vinyl acetate resin, a polyurethane, a silicon resin, or a fluororesin is preferably used.
[0014]
As an example of natural wood-like mimics, pseudo-trees with old wood motifs have been described above. However, the natural wood-like mimics of the present invention are not limited to pseudo-trees. May be prepared using the motif.
[0015]
Next, usage examples of the natural material-like mimics of the present invention will be described with reference to FIG. 3, FIG. 4, and FIG.
FIG. 3 is a bird's-eye view of the promenade, which is a pavement made by combining four pseudo trees 1 in the present invention into a set. FIG. 4 shows a garden furniture composed of a pseudo tree 1 according to the present invention, and a plate-like pseudo tree 1 and a columnar pseudo tree 1 are combined to form a table and a bench. FIG. 5 shows an example of the structure of a flower bed by using the pseudo tree 1 according to the present invention as a retaining ring. In the pseudo tree of this example, the reinforcing reinforcing bars are arranged in the base material 11 and the base material 11 is reinforced in the concrete base material. However, when the high strength is not particularly required, the concrete base material may be unreinforced.
