[Purpose of invention]

[Technical field to which the invention belongs and the prior art in that field]

The present invention relates to a concrete product that is used under environmental conditions in which microorganisms and plants can grow. In particular, the present invention relates to a concrete product for promoting greening suitable for greening the surface of a concrete product body.

In recent years, reassessment of the natural environment, especially the natural landscape and urban landscape, has been considered important. Above all, the banks of rivers, the walls of rivers and coastal embankments, the protective walls of railroad tracks, and the side walls of roads are made of gray concrete which gives a cool feeling. Has been.

In response to the social requirements for green landscape, plant-grown concrete product blocks and greening concrete were developed and produced. The former plant growth concrete has a structure of a porous concrete block filled with a plant growth base material of mineral special soil in which the seed of the plant is sown, so that the concrete surface is covered with green for several months.

As for the latter, the product is intended to be applied primarily to structures and was developed for the purpose of greening roofs and walls of buildings. It is designed to cover the covering of the porous concrete surface and sow plant seeds there.

On top of that, water purification concrete, which attempted to purify water quality by propagation of aquatic plants, was also experimentally developed at the research stage. The plan is to create porous concrete and allow aquatic plants to grow in that space.

In the plant growth concrete block described above, since seeds of plants are sprayed in the middle of the porous concrete block in advance, greening can be achieved in a short period of several months. In any case, the open area on the surface of the space of the porous concrete block filled with special soil is very small in terms of the surface area of the block, and thus the amount of plants to be grown, that is, the amount of greening, is limited. Also, greening can never be achieved unless the seeds are scattered and sown.

In the case of greening concrete, greening cannot be achieved at all, unless seeds are sprayed on the covering of the surface of the porous concrete.

In addition, as long as the seeds of aquatic plants are not planted in the space part of water-purifying concrete composed of porous concrete, a very long period of time is required for the aquatic plants to grow naturally.

[Technical problem to be achieved]

As discussed above, the greening of concrete media is difficult unless the seed of the plant is filled or planted in the concrete product according to various conventional greening means in concrete products.

As described above, the present invention has been made in consideration of the problems of the prior art, and its object is to make the surface of the concrete product main body easy to settle by microorganisms so that it does not need to fill or plant seeds in the concrete product body. It is to provide a greening concrete product in which the seed of the plant sprouts and grows to realize greening, and when the concrete product is used in water, the concrete product achieves purification of water through the formation of an organic membrane by the settlement of microorganisms.

[Configuration of Invention]

In order to achieve the above object, in the concrete product for greening promotion according to claim 1, a predetermined portion of the outer surface of the body of the concrete product to be used in an environment in which the amount of water required for seed germination is supplied. In green concrete for promoting greening of carbon fiber, the carbon fiber has a thickness of several micrometers to several tens of micrometers that is flexible and warpable so that it can be knitted or woven into fabric. Very thin carbon fiber filaments are concentrated in rows on strands, one end of which is embedded in the body of the concrete product, and the non-expression end side is scattered in water so that each filament can swing freely. It was configured to be. Each filament scattered in water fluctuates like a plant or a tank depending on the wave or water flow.

Claim 2, wherein in the concrete product for greening promotion according to claim 1, a strand-like focusing body of the carbon fiber filament is planted at a predetermined interval on the concrete product body, Carbon formed in the form of a mat in which a flexible and flexible carbon fiber filament is compressed on the front of the planting area of the strand-like focusing body so as to surround the strand-like focusing material of the carbon fiber filament. The fiber nonwoven fabric was laid so that the non-fixed end side of the strand-like focusing body of the carbon fiber filament protruded above the mat-shaped carbon fiber nonwoven fabric. Carbon fiber nonwovens formed in the form of mats promote the attachment of microorganisms in the air or in water, and flying plant seeds.

Claim 3 is a braided material for weaving and tying a part embedded in at least a concrete product body of a strand concentrator of carbon fiber filaments according to claim 1 or 2 according to claim 1. Iii) was formed. The braid facilitates the fixing of the rebars disposed in the body of the concrete product.

Claim 4 is a protection member for the greening-promoting concrete product according to claim 3, wherein at least a portion of the portion embedded in the concrete body of the strand of the carbon fiber filament embedded in the concrete body of the carbon fiber filament is a protective member. It was configured to cover. The protective member prevents the breakage of the carbon fiber filament.

In claim 5, in the concrete product for greening promotion according to claim 4, the protection member is made of synthetic resin or rubber, which is rich in elasticity and is less likely to cause damage to carbon fiber filaments.

Claim 6 is a high-strength which surrounds a protection member in the site | part which faces the concrete product main-surface part of the strand-shaped concentrator of carbon fiber filament in the concrete for greening promotion of Claim 4 or 5. And a cylindrical cylindrical second protective member having excellent durability. An elastic-rich adhesive can be filled inside the cylindrical second protective member, thereby increasing the bending stiffness of the braid portion.

Next, the operation of the present invention will be described.

Carbon fibers have a positive charge, and a large number of microorganisms in air or water tend to have a negative charge. Therefore, microorganisms tend to adhere to the carbon fibers planted on the surface of the concrete product body. In particular, by forming a carbon fiber filament in the form of a strand focused, or by combining the strand-like focusing body and a mat-shaped molded body compressed into a non-woven fabric, the surface of the concrete product body The surface area of the carbon fiber to which microorganisms can settle can be largely secured.

Under the environment in which water is supplied to the carbon fibers, microorganisms fixed on the carbon fibers are sludged. In particular, dust or garbage floating in the air under dusty environments such as sidewalls of roads is attached to carbon fibers as deposits. Seeds of plants that fly naturally and attach to carbon fiber germinate and grow as nutrients in sediment.

In the case of concrete products installed under water, greening by the germination and growth of seeds floating in the water and adhering to the carbon fiber is added, and an organic membrane is formed by the microorganisms attached to the carbon fiber, thereby purifying water.

The protective member covering the carbon fiber of string or braid reduces the load acting on the root part of the carbon fiber molded body planted in the concrete product body, and also prevents the fiber filament from making direct contact with the concrete body when the carbon fiber molded body is rocking. Prevent it.

Best mode for carrying out the invention

Preferred embodiments of the present invention will be described by way of example based on the accompanying drawings.

1 to 5 show an embodiment in which the present invention is applied to a concrete reinforcement block for building a soil protection wall to form the arc of the arc in the pump type dam, Figure 1 is a pumped dam configured by stacking the concrete reinforcement block of the first embodiment Fig. 2 is a cross-sectional view of the concrete reinforcement block forming the normal surface of the arc, Fig. 3 is an explanatory view of the manufacturing process of the copper block, and Fig. 4 shows the state of bonding the carbon fiber bundle to the water-soluble tape. 5 is a view for explaining the action of the carbon fiber filament.

This concrete reinforcement block 10A is extremely thin (e.g., several microns in diameter) to tens of microns in diameter, as shown in FIGS. 1 and 2, and bundles of easy-to-bend carbon fiber filaments 15 Carbon fiber bundles 14 formed on the surface of a rectangular flat block body 12 made of dense concrete at predetermined intervals are integrally formed.

On the other hand, although the bundle 14 is planted in all the concrete reinforcement blocks 10A of FIG. 1, the bundle 14 is only shown for a portion of the concrete reinforcement block 10A, and the illustration of the bundle 14 in the other block 10A is omitted.

In order to manufacture this block 10A, concrete is first poured into mold 16 to a predetermined depth, as shown in Fig. 3 (a). Next, as shown in FIG. 4, the bundles 14 are continuously integrated and arranged at a predetermined interval to form an integrated bundle continuum W by sandwiching the ends of the carbon fiber bundles 14 with the band-shaped water-soluble tapes 17 and 17. do. As shown in FIG. 3 (b), the plurality of bundle continuums W are kept at a uniform interval with the carbon fiber bundle 14 in a straight line and the tape 17 is placed on the inner bottom of the mold 16, and dense concrete is poured again. When the concrete is hardened, the tape 17 is completely dissolved in the concrete, and the carbon fiber bundles 14 are planted at cross-equal intervals on the surface of the block body 12 to form a concrete reinforcement block as indicated by reference numeral 10A in FIGS. 1 and 2. .

Next, the case where concrete reinforcement block 10A is used as an anti-sewing wall for forming the arc surface of the pumped dam is described.

The concrete reinforcement block 10A is stacked on the mountain 30 in the form of carbon fiber bundle 14 facing the arc. Therefore, as shown in FIG. 5, the carbon fiber bundle 14 extends about perpendicularly to the surface of the concrete block body 12, and the end portion thereof is self-weighted. In the air, the carbon fiber filament 15 remains bundled to a certain extent, but in the water, the carbon fiber filaments 15 are scattered with each other and appear fusiform, and shake like plants or water tanks due to waves or water flow. Therefore, considering that carbon fibers are easily charged in a positive state and microorganisms are easily charged in a negative state, there is a tendency for microorganisms living in water to settle in the carbon fiber filament 15 which is always under water. Since carbon fiber filament 15 spreads and shakes in water, there are many opportunities for contact with microorganisms, and carbon fiber filaments are likely to cause microorganisms to settle. Thus, carbon fiber filament 15 results in the settling of the inorganic membrane to purify the water. When the aquatic plants floating in water settle in the carbon fiber filament 15, the growth of the germinated aquatic plants is promoted, and the greening state is shown by the propagation of the aquatic plants.

In a pumped dam, the surface level of the lake generally varies to several meters of height, but the carbon fiber filament 15, located near the water surface, is always in a moist environment, so that microbes in the atmosphere or in the water are easily attached to the carbon fiber filament.

Because of this, when the seeds of plants floating on the surface of water adhere to the carbon fiber filaments and germinate, they take the corpses of microorganisms as nutrients and accelerate their growth, providing a rich greening state in which the plants have grown.

6 and 7 show a second embodiment of the present invention. 6 is a cross-sectional view of the concrete reinforcement block, and FIG. 7 is an enlarged cross-sectional view around the lower end of the carbon fiber bundle.

The concrete reinforcement block 10B has a lower layer 12A made of dense concrete, and the upper layer 12B made of porous concrete is stacked thereon, and the carbon fiber bundle 14 is planted on the upper layer 12B to be integrated.

The lower end of the bundle 14 is covered with a thermoplastic film 18 as a protective member, whereby the carbon fiber filament 15 does not come into contact with the concrete body 12, thereby preventing the carbon fiber filament 15 from being damaged.

On top of that, since the carbon fiber bundle 14 is covered with the plastic film 18, the bending rigidity is improved in the vicinity of the root 14a of the bundle and the bending stress acting on the root 14a of the bundle is reduced, which does not easily cause breakage of the carbon fiber filament 15. It becomes

The plastic film 18 is formed by winding a band-shaped film 18a around the bundle 14, and the number of windings of the band-shaped film 18a increases as the bottom portion of the bundle 14 increases, and the portion of the bundle 14 embedded in the block body 12 goes toward the bottom portion thereof. The growing inverse taper structure is made.

Therefore, the fall prevention action of the plastic film 18 (the reverse taper structure at the bottom of the bundle) allows the bundle 14 to withstand long-term use without falling out, with the carbon fiber filament 15 standing vertically and at the top side. Sufficiently maintained in oscillation due to air or water flow.

In the second embodiment described above, the plastic film 18 has a structure covering the entire buried portion of the bundle 14 to the block body 12. However, the plastic film 18 should just cover the site | part which faces the surface layer part of the block main body 12 at least. The plastic film may be replaced with a rubber band. In other words, the material of the protective member covering the carbon fiber bundle 14 may be a resin or rubber rich in weather resistance that does not damage the carbon fiber filaments.

Figure 8 shows a third embodiment of the present invention, showing a cross section of a concrete reinforcement block.

At 10 DEG C of the concrete reinforcing block, the entire block body 12 is made of porous concrete, and the carbon fiber nonwoven fabric 20 in which the lower surface part is embedded in the block body 12 is integrally formed on the surface of the block body 12.

The carbon fiber nonwoven fabric 20 is formed into a mat by compression of the carbon fiber filament 15. The carbon fiber filaments 15 are intertwined and therefore easy to attach to air or underwater microbes or floating plant seeds, and can be concluded to be excellent in supporting plant growth, i.e., promoting greening.

It is. In addition, the front part of the braid 25 of the carbon fiber forming member 20B is formed in the shape of room 26, and when water flows into the U-shaped block 10E, as shown in FIG. It spreads simply and shakes like a water tank, promoting the formation of inorganic membranes (purification of water) by the attachment of microorganisms.

The part indicated by reference numeral 29 is a cylindrical metal protective member with the upper opening end taped. Since the cylindrical protective member 29 exists around the braid portion 25, the braid portion 25 does not come into direct contact with the block main body 12, and is less likely to cause breakage of the carbon fiber filament 15.

The resin adhesive is filled inside the protection member 29, and the braid portion 25 is covered with the high elastic adhesive 30. That is, the braid portion 25 is surrounded by the adhesive layer 30 which is the first protective member, and has a structure surrounded by the second protective member 29 outside thereof.

It is structured to prevent it.

In addition, an insulating resin film may be formed on the entire braid 25 instead of or in addition to the insulating film formed on the reinforcing materials 13, clips 27, 28 and the protective member 29. Furthermore, in order to prevent the erosion of electrolysis, a wire rod composed of a material which does not cause electrolysis erosion between the carbon fibers may be disposed along the reinforcing member 13 and the carbon fiber molded body 20B may be fixed to the wire rod. .

In the U-shaped block 10F shown in Fig. 13, a high elastic adhesive rich in elasticity is filled inside the cylindrical protective member 29 that protects the entirety of the braid portion 25 of the carbon fiber molded body 20B, thereby improving the bending rigidity of the braid portion 25. The stress on the 25 is reduced, resulting in a structure that further improves the durability of the braid 25. The adhesive layer 30 is formed to rise up to the branching portion between the braid portion 25 and the hem 26 to prevent the hem 26 from being separated.

On the other hand, the U-shaped block 10G shown in FIG. 14 has a structure in which the plastic film 18 is wound around the braid portion 25 facing the surface layer portion of the block body 12.
