DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for forming a surface pattern on a pseudo-rock block or a pseudo-rock block (hereinafter referred to as a pseudo-rock block).

[0002]

2. Description of the Related Art Conventionally, rivers and coastal structures have been widely formed by combining concrete blocks.

[0003] However, rivers and coastal structures formed by combining such concrete blocks are not suitable for the surrounding environment in many cases because they are exposed to an artificial feeling. The device is designed to harmonize with the environment.

[0004] By the way, this kind of artificial rock block usually has a natural stone-like texture by providing natural stone-like irregularities on the surface of a block body made of concrete, or by attaching natural stone processed into an appropriate shape. Most are exposed. And such a pseudo-rock block is easy to manufacture and is useful for places that are far away from the viewpoint and do not require much fineness, for example, such as those used directly by people. If it is used for the maintenance of a space utilizing hydrophilicity, or used in a place close to the viewpoint, it cannot be denied that the surface texture is rough and a considerable sense of incongruity occurs.

[0005] Under such circumstances, the applicant has developed a pseudo-rock block in which a surface texture including a pattern closer to natural stone is formed by combining a plurality of plate-like rock pieces using natural stone as a master. If the surface texture can be expressed more finely and freely, it can be used not only for river and coastal structures but also for more familiar items such as garden stones and indoor equipment. It becomes possible.

[0006]

Therefore, according to the present invention, there is provided a holding mold formed of a dividable hard female mold having a rough external shape such as a pseudo-rock block to be molded. Pour a surface transfer material with fluidity on the side to a specified thickness, and then place and compact the final forming material containing mortar while the surface transfer material is fluid. After curing of the final formed material, the holding mold is appropriately demolded, and the remaining surface transfer material is removed to form a pseudo-rock block or the like. It is intended to be able to form a tasteful and free surface pattern.

Further, a flexible secondary female made of rubber or the like is provided on the inner surface of a holding mold formed of a dividable hard female mold having a rough external shape such as a pseudo rock block to be molded. A mold is disposed, and then a surface transfer material having fluidity is cast into the secondary female mold to a predetermined thickness, and then, while the surface transfer material having been cast has fluidity. If the final forming material including mortar is cast and compacted, and after curing of the final forming material is appropriately cured, the holding mold and the secondary mold are removed, and the remaining surface transfer material is removed. Further, a finer and more pleasing surface pattern can be formed by the synergistic action of the compacting force of the final formed material and the flexible secondary female mold and the fluid surface transfer material.

Furthermore, after forming an uneven shape on the surface of the surface transfer material having fluidity cast on the inner surface of the holding mold frame or the secondary female mold frame with a brush or an appropriate jig, the mortar is formed. It is preferable to cast and compact the final forming material containing, because a finer and more attractive surface pattern can be expressed.

[0009]

According to the present invention, a final forming material containing mortar is cast and compacted on a surface transfer material in a flowing state, which is cast on a holding mold made of a hard female mold, so that the surface transfer material is randomly added to the surface transfer material. The mortar that has penetrated forms, for example, a serpentine-like surface pattern via the surface transfer material. And since this surface pattern will be formed in various patterns according to the shape of the holding mold and the strength of compaction force, even if the same mold and the same material are used, each will be slightly different, Therefore, two unique surface patterns can be formed.

[0010]

Next, a preferred embodiment of a method of forming a surface pattern on a pseudo rock block according to the present invention will be described in detail with reference to the drawings. It should be noted that the present invention is not limited to the illustrated embodiment, and it goes without saying that various design changes can be made without departing from the spirit of the present invention.

In FIG. 1, a basic method of forming a surface pattern on a pseudo rock block or the like according to the present invention is as follows. First, a rough external shape of a pseudo rock block A to be molded can be molded and divided into several parts. For example, a holding mold frame 10 made of a hard female mold made of FRP resin or the like is prepared, and a silicone rubber (surface transfer material) 12 having an appropriate fluidity is coated on the inner surface of the female mold frame 10 by about 0.5 cm. Pour it to the thickness. As the surface transfer material, besides silicon rubber, for example, various materials such as grease, agar, paraffin, and mortar may be used as long as they have appropriate fluidity and can be easily removed from the holding mold 10. Can be. When mortar is used as the surface transfer material, it is preferable to mix a curing retarder.

Next, while the silicone rubber 12 has fluidity, the resin-based mortar 14 is similarly made, for example,
It is cast to a thickness of 2 cm or more and the worker compacts it manually. In this case, the surface of the resin-based mortar 14 in contact with the silicone rubber 12 is randomly formed on the silicone rubber 12 having fluidity according to the strength of the compaction force of the worker and the shape of the hard holding mold 10. Bites into and is compacted into a complex shape. Also, as described above, the silicone rubber 12
As a material to be poured while the material has fluidity, for example, mortar concrete or the like can be used in addition to the resin mortar 14.

After the compaction of the resin-based mortar 14 is completed, concrete 16 is then poured.
The resin mortar 14 and the concrete 16 are cured. When the final forming material 18 including the resin-based mortar 14 and the concrete 16 is cured, after curing for a predetermined period, the holding mold 10 is separated and removed from the mold. The pseudo rock block A is formed by spraying high pressure water or the like onto the silicon rubber 12 to be removed.

The pseudo rock block A thus obtained
Although the general appearance is along the holding mold 10, the surface portion thereof has a silicone rubber 12 having fluidity.
The resin-based mortar 14 is hardened in a state of biting randomly, so through this silicon rubber 12, for example, a subtle and tasteful surface pattern B like serpentine is formed, and it becomes more natural stone. A pseudo rock block A having a close surface texture can be obtained.

Since the surface pattern B is formed in various shapes according to the strength of the compaction force of the operator and the shape of the holding mold 10, even if the same mold and the same material are used, it is delicate. Thus, a pseudo-rock block having two unique surface patterns can be obtained. In this case, it is needless to say that if a suitable pigment or the like is mixed into the resin-based mortar 14, a texture closer to natural stone can be obtained.

FIG. 2 shows a holding mold 10 made of a hard female mold made of, for example, FRP resin or the like, which can form a rough external shape of the pseudo rock block A to be molded and can divide it into several parts. An elastic female mold (secondary female mold) 20 made of rubber or the like and formed by transferring a natural stone outer surface is disposed on the inner surface of the elastic female mold 20.
The silicone rubber 12 having fluidity is cast into a predetermined thickness, and then the resin-based mortar 14 is similarly cast into a predetermined thickness while the silicone rubber 12 has fluidity. An operator compacts the concrete by hand, further casts concrete 16, hardens and cures the final forming material 18 including the resin-based mortar 14 and the concrete 16, and then separates and removes the hard holding mold 10 from the mold. Elastic female formwork 20
Is peeled off, and the remaining silicone rubber 12 is removed from the surface portion of the obtained molded article a to form the pseudo rock block A having the surface pattern B.

The pseudo rock block A thus obtained by the method shown in FIG.
The surface pattern is not only formed with a subtle and interesting surface pattern, but also on the surface part thereof, due to wrinkles and streaks of the elastic female mold (secondary female mold) 20. The resulting irregularities subtly affect the silicone rubber 12 having fluidity, and are hardened in a state formed as a deep or shallow groove or the like in the resin mortar 14 that has randomly bitten into the silicone rubber 12. It is formed as a more attractive surface pattern than the method of (1). In this case, since the compacting force of the operator and the rigid holding mold 10 are formed in various shapes according to the shape, even if the same mold and the same material are used, a subtle difference occurs. Therefore, it is a matter of course that a pseudo rock block having two unique surface patterns can be obtained.

Further, in the embodiment shown in FIG. 2, the silicon rubber 12 cast on the inner surface of the elastic female frame (secondary female frame) 20 is provided with unevenness 22 such as a stripe by brush or the like. If the resin-based mortar 14 is cast and the worker compacts it by hand, the surface pattern B of the obtained pseudo-rock block A is synergistic with the elastic female mold (secondary female mold) 20 and the uneven shape 22. By the action, a more subtle and attractive pattern is formed (see FIG. 3). In the case of the embodiment shown in FIG. 1, it is preferable that the silicon rubber 12 cast on the inner side surface of the holding mold frame 10 be provided with irregularities 22 such as stripes with a brush or the like.

[0019]

As described above, according to the method for forming a surface pattern on a pseudo-rock block or the like according to the present invention, the surface portion having a rough external shape along a holding mold formed of a hard female mold is provided. Not only can mortar bitten into the surface transfer material that had fluidity to form serpentine-like surface patterns, but also individual and subtle depending on the strength of the mortar compaction force and the shape of the formwork Therefore, the present invention has an advantage that two interesting surface patterns can be formed even if the same mold and the same material are used.
