For this purpose, a vegetation base material holder 5 is provided. And this vegetation base-material holding body 5 is fastened to the said tatami 3 side by the fastening member 6 planted in the normal concrete part 2 as a concrete part. In the illustrated embodiment, since the tatami 3 itself is also fastened by the fastening member 3, the vegetation base material holder 5 is usually used as a concrete part together with the tatami 3 by the fastening member 3. It can be said that it is tightened to the concrete part. The fastening member 6 indirectly clamps the vegetation base material holder 5 via a fastening plate 7 disposed on the upper surface of the vegetation base material holder 5.
[0015]
Further, the tatami 3 is a tatami that is cut into a rectangular shape so as to cover the front surface of the ordinary concrete part 2 almost entirely, and can be used as an organic fertilizer for promoting the growth of plants. It is a member and has excellent water retention.
[0016]
The vegetation base material holder 5 provided on the surface side of the tatami 3 is composed of a frame body 5b including a plurality of frame portions 5a and 5a that form an accommodation space S in which the vegetation base material 4 is accommodated. . The frame body 5b as the vegetation base material holding body 5 is framed by using, for example, thinned wood, and a plurality of vertically arranged in parallel with each other on the surface side of the tatami 3, for example, from a thickness of about 20 mm The first thinned material 5c, 5c and the upper side of the first thinned material 5c, 5c crossing each other and arranged side by side in parallel, for example, a second thinned material having a thickness of about 20 mm 5d and 5d. In the illustrated embodiment, the five first thinning materials 5c and 5c are provided at regular intervals, and the five second thinning materials 5d and 5d are also provided at regular intervals. ing. Therefore, the plurality of frame portions 5a and 5a correspond to the respective divided portions partitioned by the first and second thinned materials 5c, 5c, 5d and 5d, which are framed in a lattice shape, and each of these divided portions. An accommodation space S for accommodating the vegetation base material 4 is formed on the inside. And the 1st thinning materials 5c and 5c and the 2nd thinning materials 5d and 5d are integrally connected by the pin members 5e and 5e which connect both in the site | part where both mutually cross | intersect.
[0017]
Further, the frame body 5 b as the vegetation base material holding body 5 also serves as a tatami mat attachment body for attaching the tatami 3 to the front side of the ordinary concrete portion 2. That is, the vegetation base material holding body 5 is attached to the ordinary concrete portion 2 so that the tatami 3 is not separated from the ordinary concrete portion 2 by being provided on the surface side of the tatami 3 and supporting the tatami 3. It is fixed.
[0018]
The fastening plates 7 and 7 arranged on the upper surface of the vegetation base material holder 5 are positioned substantially parallel to the first thinned materials 5c and 5c, and the upper surfaces of the second thinned materials 5d and 5d. In the case of the illustrated embodiment, a vegetation base material holder 5 (second thinning), which is a long plate-like member having substantially the same length as the first thinning materials 5d and 5d arranged to cross. It is provided at two locations on the left and right sides of the upper surface of the material 5d, 5d). And the fastening member insertion hole (through the said fastening members 6 and 6 which penetrates to the thickness direction in the appropriate location (in the case of illustration embodiment) of the fastening plates 7 and 7 penetrates, in the thickness direction. (Not shown) is provided. The fastening members 6, 6 inserted through these fastening member insertion holes (not shown) are so-called anchor bolts whose distal end portions are bent at a substantially right angle and are implanted in the ordinary concrete portion 2. Then, the vegetation base material holder 5 is interposed via the fastening plates 7 and 7 by screwing female screw members 8 and 8 such as square nuts into male screw portions formed on the heads of these anchor bolts. Indirectly, it is fastened together with the tatami 3 to the ordinary concrete portion 2 side.
[0019]
The vegetation base material 4 held by the vegetation concrete block 1 is made of, for example, a spraying material 4a formed by mixing soil with a fertilizer, an adhesive, and the like. But the vegetation base material 4 should just contain the soil at least, and addition of a fertilizer or an adhesive material is arbitrary, and, besides soil, a fertilizer, an adhesive material, as needed, for example, a seed , Soil active material (soil improving material), water retention material, etc. may be mixed.
[0020]
Next, a method of spraying the spray material 4a as the vegetation base material 4 on the concrete block for vegetation according to the first embodiment, and the process of germination and growth of plants from the vegetation base material 4 will be described with reference to FIG. And it demonstrates based on FIG.
[0021]
First, in order to construct the retaining wall Q using the vegetation concrete block 1, a plurality of concrete blocks 1, 1 are arranged side by side and stacked up diagonally so that the surfaces of the tatami mats 3, 3 face upward. Thus, the retaining wall Q having the required inclination angle is constructed.
[0022]
And the spraying material 4a as the said vegetation base material 4 is sprayed toward the surface of the said some tatami 3 and 3 which comprise the slope of this retaining wall Q. As shown in FIG. Then, the spraying material 4a as the vegetation base material 4 is deposited to such a thickness that the vegetation base material holders 5 and 5 provided on the surface side of the tatami mats 3 and 3 are completely hidden. The vegetation layer 10 covered with the vegetation base material 4 is formed on the surface side of 3. Incidentally, in the illustrated embodiment, the vegetation layer 10 is formed to a thickness of about 50 mm. The vegetation layer 10 is formed because the vegetation base material 4 is firmly held by the vegetation base material holders 5 and 5, and the vegetation base material holders 5 and 5 have the first vegetation layer 10. The two thinning materials 5d and 5d dampen the vegetation base material 4 that tends to flow downward. And when the seed is not contained in the spraying material 4a as the said vegetation base material 4, a seed of a plant is sowed or sprayed on the surface of the vegetation layer 10, and a spraying process is completed.
[0023]
Then, the plants 11 and 11 come to germinate from the seeds contained in the vegetation base material 4 forming the vegetation layer 10 by passing through the date. When the plants 11 and 11 further grow, the roots 11a and 11a of the plants extend to the inside of the tatami mats 3 and 3, respectively. Then, since the plants 11 and 11 continue to grow while absorbing the nutrients of the tatami mats 3 and 3 that have been converted to organic fertilizer by corrosion, the growth is actively promoted, and as a result, the slope of the retaining wall Q is increased. Vegetation over a long period. Instead of such tatami mats 3 and 3, other tatami mats such as tatami floors and tatami mats may be used. These tatami mats such as tatami mats 3, 3, tatami floors or tatami mats are also excellent in water retention. Further, when using tatami mats such as used tatami mats, tatami floors or tatami mats, which are difficult to dispose of, it is preferable because industrial waste can be effectively reused. Of course, when using tatami mats such as used tatami mats, tatami floors or tatami mats, there is also an advantage that the product cost can be kept low.
[0024]
Moreover, since the said vegetation base-material holding bodies 5 and 5 are comprised from a thinning material, the effective utilization of resources can be aimed at.
[0025]
Note that the concrete block for vegetation according to the present invention is not limited to the above-described embodiment, and various other modifications are possible. For example, the vegetation concrete block 1a according to the second embodiment of the present invention includes a pair of retaining walls 2a and 2a that are formed to protrude rearward on the rear side, as shown in FIGS. Further, the ordinary concrete part 2, the porous concrete part 12 integrated with the ordinary concrete part 2 and located on the front side thereof, and the tatami mat 3 disposed between the ordinary concrete part 2 and the porous concrete part 12 3. A tatami mat such as a tatami floor or a tatami mat. And the vegetation base material holding body 5 for hold | maintaining the said vegetation base material 4 is provided in the surface side of the said porous concrete part 12 so that the vegetation base material 4 may be hold | maintained on the surface. The vegetation base material holder 5 is fastened to the porous concrete portion 12 side by fastening members 6 and 6 planted in the ordinary concrete portion 2. In the illustrated embodiment, the fastening members 6, 6 indirectly clamp the vegetation base material holder 5 via fastening plates 7, 7 disposed on the top surface of the vegetation base material holder 5. .
[0026]
Further, the concrete block for vegetation 1a is composed of the normal concrete portion 2 and the porous material by tatami mats such as tatami mats 3, 3, tatami floors or tatami mats, which are arranged between the normal concrete portion 2 and the porous concrete portion 12. In order to avoid that the concrete part 12 is divided from each other, the concrete part 12 has an integral part 13 where the concrete parts 2 and 12 are integrated. That is, a plurality of tatami mats such as tatami mats 3, 3, tatami floors, or tatami mats are arranged on the front surface of the ordinary concrete portion 2 so as to be spaced apart from each other, and the ordinary concrete is disposed at the spaced space. The integral part 13 in which the part 2 and the porous concrete part 12 are integrated is formed. However, the integrated portion 13 is formed by arranging a tatami mat such as a tatami mat 3, a tatami floor or a tatami table so as to be spaced from the outer edge of the concrete block 1a for vegetation. In addition, one or a plurality of through holes are provided in the tatami mat such as the tatami mat 3, the tatami floor or the tatami surface, and the ordinary concrete portion 2 and the porous concrete portion 12 are allowed to be integrated through the through holes. A communicating portion may be formed.
[0027]
The porous concrete portion 12 has a large number of voids 12a, 12a produced by mixing coarse aggregates such as large crushed stones and other reinforcing materials into mortar or cement milk, A vegetation part can be formed by filling these many voids 12a and 12a with soil and allowing the plants 11 and 11 to take root in the soil.
[0028]
By the way, the concrete block for vegetation 1a is such that the vegetation base material holder 5 is provided on the surface side of the porous concrete portion 12, and the vegetation base material support body 5 is composed of tatami mats 3, 3, The vegetation concrete block 1 is different from the vegetation concrete block 1 of the first embodiment provided on the surface side of a tatami mat such as a tatami floor or a tatami mat, but the other configuration is the same as that of the vegetation concrete block 1 of the first embodiment. It is almost the same.
[0029]
In addition, the method of spraying the spray material 4a as the vegetation base material 4 onto the concrete vegetation block 1a of the second embodiment and the process in which the plants 11 and 11 germinate and grow from the vegetation base material 4 are also fundamental. Specifically, it is almost the same as that described in the concrete block for vegetation 1 of the first embodiment. However, the concrete block 1a for vegetation is, as shown in FIG. 6, a spraying material 4a as the vegetation base material 4 sprayed on the surface side of the porous concrete portions 12 and 12 constituting the slope of the retaining wall Q. Is deposited on the surface side of the porous concrete portion 12 to form the vegetation layer 10, and enters the void portions 12a and 12a of the porous concrete portions 12 and 12, and is filled in the void portions 12a and 12a. Thus, it is different from the concrete block 1 for vegetation of the first embodiment. Therefore, as shown in FIG. 7, when the plants 11, 11 germinate from the vegetation base material 4 that forms the vegetation layer 10, the roots 11 a, 11 a of the plants 11, 11 become the gap portions 12 a of the porous concrete portions 12, 12, 12a is extended to the side where the tatami mats such as tatami mats 3, 3, tatami floors or tatami mats are located, and absorbs nutrients from the tatami mats such as tatami mats 3, 3, tatami floors, tatami mats etc. Thus, the growth of the plants 11 and 11 is promoted.
[0030]
Thus, since the concrete block 1a for vegetation of the second embodiment can fill the gaps 12a and 12a of the porous concrete parts 12 and 12 with soil, the gaps 12a and 12a are filled with the soil. Filled soil may be used, and the vegetation base 4 does not necessarily have to be mixed with soil. In this case, the vegetation base material 4 does not need to be made of the spray material 4a. For example, a vegetation sheet in which seeds, fertilizers, etc. are attached or sandwiched on a sheet material such as a nonwoven fabric or paper, or the vegetation sheet is used as a net. The vegetation sheet net 4b attached and reinforced may be used. In order to hold the vegetation sheet net 4b as the vegetation base material 4 on the surface side of the porous concrete portion 12, for example, as shown in FIG. When the frame 5b serving as the vegetation base material holding body 5 is clamped to the porous concrete part 12 side by the fastening members 6 and 6 by being arranged so as to be sandwiched between the body 5b and the porous concrete part 12 Good.
[0031]
In addition, the vegetation base material 4 hold | maintained at the concrete blocks 1 and 1a for vegetation of 1st and 2nd embodiment is not limited to the above-mentioned vegetation sheet, the vegetation sheet net | network 4b, or the spraying material 4a, For example, It may be a vegetation mat or a bag-like vegetation bag 4c filled with soil or the like. As shown in FIG. 9, the vegetation bag 4 c as the vegetation base material 4 is provided in a housing space S formed inside the frame portions 5 a and 5 a provided in the frame body 5 b as the vegetation base material holding body 5. The single vegetation bag 4c or the plurality of vegetation bags 4c, 4c are accommodated so as to be tightly held, so that they are held on the surface side of the tatami mat or the porous concrete portion 12. Thus, the vegetation base 4 is not particularly limited as long as it has a form that can be held by the vegetation base holder 5 and can be a base that promotes the growth of the plants 11 and 11. Absent.
[0032]
Moreover, if the concrete block 1 for vegetation and 1a are concrete blocks aiming at vegetation, it can implement not only to the concrete block for retaining walls but to the concrete block of various uses.
[0033]
Moreover, in the concrete block 1 for vegetation of 1st embodiment, the said concrete part is comprised from the normal concrete part 2 and the porous concrete part integrated with the normal concrete part 2 and located in the front side. It may be a thing. In this case, the porous concrete portion is formed so as to be positioned between the ordinary concrete portion 2 and a tatami mat, a tatami floor, or a tatami mat, and the tatami mat, such as the tatami mat, the tatami floor or the tatami mat, is porous concrete. It will be attached to the front side of the part. Furthermore, in this embodiment, a tatami mat such as a tatami mat, a tatami floor, or a tatami surface may be disposed between the ordinary concrete portion and the porous concrete portion.
[0034]
Moreover, you may comprise so that the porous concrete part 12 may be located inside the normal concrete part 2 in the concrete block 1 for vegetation of 1st embodiment. That is, in this case, as shown in FIG. 10, the concrete portion is formed from the normal concrete portion 2 covering the central portion made of the porous concrete portion 12 and the side and back surfaces of the central portion made of the porous concrete portion 12. The tatami mat, the tatami floor, or the tatami mat is attached to the front surface of the center portion composed of the porous concrete portion 12 and the frame portion composed of the ordinary concrete portion 2.
[0035]
In this way, the concrete blocks for vegetation 1 and 1a can be applied to the plants 11 and 11 sprouting from the vegetation base material 4 so that the tatami mats such as the tatami mats, the tatami floor or the tatami mat can function as organic fertilizers. A tatami mat, such as a tatami floor or a tatami mat, may be attached to the normal concrete portion 2 and / or the front surface side of the porous concrete portion 12 or the rear surface side of the porous concrete portion 12.
[0036]
In addition, the vegetation base material holding body 5 is not particularly limited to the wooden frame body 5b formed by using the wood such as the thinned material as long as the vegetation base material holding body 5 can hold the vegetation base material 4. For example, the vegetation base material holding body 5 may be a net body made of synthetic resin or metal, and the net body may be a surface side of a tatami mat such as a tatami mat, a tatami floor or a tatami mat or a porous concrete portion 12. For example, it may be fixed on the surface side of the concrete part such as a pin by a fixing member such as a pin.
[0037]
Further, the vegetation base material holder 5 needs to be indirectly tightened via the tightening plates 7 and 7 when the tightening members 6 and 6 are tightened to the concrete portion side such as the ordinary concrete portion 2 or the like. There is no. For example, the vegetation base material holder 5 is provided with fastening member insertion holes at appropriate positions, and is a fastening member implanted in a concrete part such as the normal concrete part 2 inserted through the fastening member insertion holes. 6, 6 may be directly tightened to the tatami mat or the porous concrete portion 12 side.
[0038]
Furthermore, the vegetation base material holder 5 does not necessarily have to serve as a tatami material attachment body for attaching the tatami mat material to the front side of the concrete part or the porous concrete part, and is different from the vegetation base material support body 5. Other members may serve as the tatami mat attachment body.
[0039]
【The invention's effect】
As described above, as is clear from the detailed description, according to the concrete block for vegetation according to the present invention, the loss of the vegetation base material is prevented, and the tatami mat that is provided with water retention and becomes organic fertilizer by corrosion, Plant growth is promoted.
