Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a decorative material unit used on the surface of a concrete structure and a method for manufacturing this decorative material unit, and in particular to a decorative material and a connecting/fixing material by adding water. are easy to separate.

<Conventional technology and its problems> The surface of concrete structures, such as concrete retaining walls, exposes the bare surface of the concrete and does not fit in with the surrounding natural scenery. There was also the simplest and oldest method of assimilating the color of the trees, but according to this method, as long as you look at it from a distance, it doesn't look too strange, but as you get closer, it becomes too artificial and uninteresting as a landscape. It had become a thing.

For this reason, for example, a method was used in which a decorative flat plate with the decorative material exposed was manufactured in a factory using the so-called washing method, the decorative flat plate was assembled into a wall shape at a construction site, and concrete was poured into the gap on the back. According to this, not only does it take time and effort to manufacture and assemble the decorative flat plate, pour concrete, etc., but also requires inconveniences such as having to mold an irregularly shaped plate when used on a curved surface. there were.

Furthermore, as a method to save this time and effort, a method was also implemented in which the surface of uncured concrete was molded into a decorative surface molding plate that was shaped like natural stone to create irregularities on the concrete surface. According to the above, it is clear that the construction efficiency is improved, but the surface of the retaining wall has unevenness due to the concrete surface, which prevents it from exhibiting its natural texture.

In order to solve the above-mentioned problems, the present applicant has previously developed a method for combining a plurality of decorative materials, made of arbitrary materials such as stone 9 synthetic resin, and having arbitrary shapes, with connecting and fixing materials that can be removed after curing. The decorative material on the side where the connecting/fixing material of the decorative material unit formed by fixed connection is not present is pushed into the surface of the concrete structure before hardening, so that the connecting/fixing material can be removed after the concrete structure has hardened. The company developed a cosmetic material unit that As a result of implementing this, we were able to achieve the intended purpose, but after construction, the connection/fixation material had to be removed, and the adhesion between the decorative material and the connection/fixation material deteriorated. The finish is not very good because it is too strong and cannot be easily removed, and even if the connecting/fixing material is removed, fragments of the connecting/fixing material remain on the decorative material. There wasn't.

Means for Solving the Problems> Therefore, in order to solve the above-mentioned problems, the decorative material unit used on the surface of a concrete structure and the method for manufacturing this decorative material unit according to the present invention, in order to solve the above-mentioned problems, As a connecting/fixing material, it is possible to fix and connect multiple decorative materials of any shape using any material such as stone coated with a water-soluble substance 9 synthetic resin, and especially by adding water, the decorative material and the connecting/fixing material can be bonded together. This makes it easier to separate.

Embodiment Example This embodiment relates to the invention described in claims 1 to 5, that is, a cosmetic material unit 1. In the figure, 2 is a cosmetic material unit molded from natural stone or synthetic resin Pseudo-kun etc. are a plurality of cosmetic materials made of arbitrary materials and having arbitrary shapes.

In addition to the above materials, the decorative material 2 may also be, for example, shells, sand, gravel, etc. 3 is a water-soluble substance (for example, polyvinyl alcohol) coated on the surface of this cosmetic material 2, and 4 is a connecting/fixing material that connects this cosmetic material 2 together. The connecting/fixing material 4 should be made of a material that, in principle, has good fluidity, can be cured by some treatment, and can be removed by peeling or removing from the cosmetic material 2 after curing. In addition, since the connecting/fixing material 4 is used in other embodiments described later, it is preferable that the material is watertight and can be driven with a nail after hardening.For this purpose, for example, natural rubber is used. Alternatively, it is made of a rubber material such as synthetic rubber, a polymer resin, wax, or the like.

Further, the decorative material 2 is disposed so as to protrude from the surface of the connecting/fixing member 4, but it is preferable that the decorative material 2 is disposed so as to have different degrees of protrusion as shown in FIG.

<Example ■> This example relates to the invention described in claims 5 to 8, that is, a method for manufacturing a cosmetic material unit. This is a formwork for molding the material 4, and several pieces of the decorative material 2 are placed in this formwork 5, as shown in FIG. In this case, the polyvinyl alcohol solution 3 is adhered to the surface of the cosmetic material 2 with no moisture present (or extremely little moisture if present). Examples of methods for adhesion include painting, spraying, and dipping.
Then let it dry. This allows a strong film to be formed on the surface of the cosmetic material 2. The decorative material 2 in this state is then arranged in the mold 5. Then, as shown in the same figure (b), the connecting/fixing material 4 described in the example construction is inserted, and this connecting/fixing material 4 is inserted.
After curing, other decorative materials 2 are arranged as shown in FIG. In this way, when putting the cosmetic material 2, the arrangement of the cosmetic material 2 is taken into consideration.In any case, when the cosmetic material 2 is put into the mold 5, about half of the upper part of the cosmetic material 2 is filled with the cosmetic material. It will be exposed above the liquid level of 2. and the connecting/fixing material 4
When synthetic rubber is used as the rubber, it is solidified by heating or the like. The decorative material unit 1 formed in this manner can be removed from the mold frame 5. Furthermore, if a decorative joint material such as fine aggregate is inserted during the hardening of the connecting/fixing material 4 and is adhered to the connecting/fixing material 4, it can also serve as a decorative joint material. Furthermore, since the connecting/fixing material 4 may be nailed in the usage example described later, the hardened connecting/fixing material 4 must be able to withstand nailing or adhesive fixing to a template. In some cases, before pouring the connecting/fixing material 4 into the formwork 5, the substrate 6 is set at the bottom of the formwork 5 (see FIG. 4). This board 6
If it has the strength as a template, it can be used as a template, and it is also convenient to transport.

<Example of use ■> The method of disposing the decorative material unit shown in Example ■ obtained by the method of Example H above on a concrete structure, that is, the method of applying decoration to the surface of a concrete structure is as follows. It is. In addition, concrete structures here include, for example, concrete retaining walls, walls of concrete buildings, inner walls of garden oil, various concrete blocks such as blocks for seawalls or blocks for fish reefs, fences, walkways, etc. shall be included. Here, we will first discuss the concrete block as an example. In Fig. 5, 7 is a formwork for molding the concrete block 8, and as shown in Fig. 5 (a), inside this formwork 7. Before pouring concrete 9, a decorative material unit 1 is set at the bottom of a formwork 7. In this case, the cosmetic material unit 1 is set so that the side (surface) on which the cosmetic material 2 is exposed faces upward. Thereafter, when concrete 9 is poured from above the decorative material unit 1 as shown in FIG. As it adheres, this moisture permeates the adhesive surface between the cosmetic material 2 and the connecting/fixing material 4 as if flowing along the surface of the cosmetic material 2.
The water-soluble substance 3 coating the cosmetic material 2 is dissolved. This will be done continuously while the concrete 9 contains water, and the adhesion between the decorative material 2 and the connecting/fixing material 4 will be separated. Even if the decorative material 2 is separated by pouring the concrete 9 in this manner, the decorative material 2 is stably fitted into the recess of the connecting/fixing member 4 and integrated with the exposed decorative material 2. In this state, the concrete 9 will eventually harden and the concrete block 8 will be completed, but after hardening, if the concrete block 8 is removed from the mold as shown in FIG.
The connecting/fixing material 4 is also separated and removed. In Example 2, it was stated that it is preferable that the connecting/fixing material 4 is watertight after hardening.
This is to prevent moisture (toro) in the concrete 9 from penetrating into the decorative material unit 1 and adhering to the decorative material 2 that will appear on the outside after construction. The present embodiment described above has been explained by taking as an example the molding of the concrete block 8 using a so-called pouring molding frame, but it can also be used in a so-called quick-release molding machine.

<Example of use ■> In addition, for a concrete retaining wall, decorative material units 1 are placed on the preliminarily constructed slope 10 with appropriate gaps maintained as shown in Fig. 6, but in this case, First, template 11
The decorative material unit 1 is attached to the inner surface of the template 11 with its connecting/fixing member 4 side facing. The decorative material unit 1 may be attached to the template 11 by, for example, nailing. Next, concrete 9 is placed between the decorative material unit 1 and the slope 10. Then, this concrete 9 flows in between the decorative material unit 1 and the slope 10 so as to sink into the exposed decorative material 2. After the concrete 9 has hardened, the template 11 and the connecting/fixing material 4 are removed, thereby exposing the decorative material 2 from the wall surface and completing the construction.

<Example of use m> Furthermore, for a horizontal surface such as a sidewalk, the decorative material unit 1 is placed on the horizontal surface 12 that has been prepared in advance, with an appropriate gap maintained, but in this case, the decorative material unit 1 is placed on the horizontal surface 12 side. 1, the decorative material 2 is set with its exposed side facing, and mortar 13 is injected between it and the horizontal surface 12. This mortar 13 flows into the space between the decorative material 2 exposed between the decorative material unit 1 and the horizontal surface 12 so as to sink into the space. When injecting the mortar 13 in this way, it is sufficient to previously drill a mortar injection port 14 in a part of the connecting/fixing member 4 of the cosmetic material unit 1. Thereafter, after the mortar has hardened, the connecting/fixing material 4 is removed, thereby exposing the decorative material 2, and the construction is completed.

<Other Examples> In addition, for example, shells may be used as a decorative material for blocks for fish reefs, etc., and glass beads may be used for fences, etc., but these decorative material units or decorative methods are also described. This is carried out in the same manner as in each of the embodiments described above.

<Effects of the Invention> As described above, according to the decorative material unit used on the surface of a concrete structure and the manufacturing method of this decorative material unit according to the present invention, since the decorative material is coated with a water-soluble substance in advance, the construction process is easy. It is useful because it is easy to remove the connecting and fixing materials later, and especially according to the manufacturing method of the decorative material unit used on the surface of concrete structures, it is easy to manufacture and does not require special skill. This has a significant effect.
