Description

Description: <Industrial field of application> The present invention relates to a building block that can be used, for example, for revetment or for retaining walls.

<Prior art> As is well known, blocks for retaining walls or retaining walls for building residential land, constructing roads and tracks are made of concrete,
Since the block has hardly treated the surface, it will be a dead landscape if a revetment or retaining wall is constructed, which will significantly hinder the natural environment and landscape. In addition, if a long time has passed after the block wall was constructed, cracks that gradually fall due to natural topographic changes, vibrations, etc. may occur, and there is a risk of collapse in extreme cases.

<Problems to be Solved by the Invention> If the surface of a concrete block is decorated in a state close to the natural environment, it becomes extremely expensive, so that it cannot be used at all when constructing a large-scale revetment or retaining wall. In addition, when the seawall or retaining wall is cracked or collapsed due to a natural phenomenon, the repair work is extremely troublesome.

Therefore, there is a demand for a building block that naturally adapts when constructed as a revetment or as a retaining wall, can be mass-produced at low cost, and is extremely rich in strength.

<Means for Solving the Problems> Since the present invention has been proposed in view of the above, the block main body (2) for tree planting is formed in the block body (2) in an oblique direction with respect to the surface facing the back surface and opening toward the back surface. The hollow portion (3) and a communication hole (5) having a diameter smaller than that of the tree-planting cavity (3) and communicating with the lower end portion (4) of the tree-planting cavity (3) and opening to the back side are provided. A notch formed on the side edge of the block body (2) with the same inclination as the tree-planting cavity (3) and the communication hole (5) and having a half shape of the tree-planting cavity (3) and the communication hole (5). A part (6) is formed, and in the state where the block main body (2) is installed in an inclined shape along the slope, the tree-planting empty part (3) is installed so as to open toward the upper side in the vertical direction, In addition, the communication hole (5) is installed vertically downward, and the block body (2) is installed continuously. By doing so, the cutouts (6) of the side edges of the adjacent block bodies (2) are matched with each other, and the tree-filling vacant space (3) and the tree-cutting vacant space of the matched cutouts (6) are provided with trees ( It is possible to plant a) in the vertical direction, and the root of the planted tree (a) passes through the communication hole (5) and the communication hole of the notch (6) which is matched with the ground. It is characterized in that it is configured to stretch inside.

<Operation> According to the present invention having the above configuration, in the state where the block main body is installed in an inclined shape along the slope, the tree-planting vacant part is installed so as to open vertically upward, and The communication holes are installed vertically downward, and the block main bodies are connected in series so that the cutouts of the side edges of the adjacent block main bodies are aligned with each other, and the empty portion for tree planting and the aligned cutouts are formed. Since it is possible to plant trees in the vertical part of the tree planting space, it is possible to plant trees in a natural state without inclining the tree saplings, which does not impair the natural environment and landscape. Further, the trees gradually grow, and the roots of the trees pass through the communication holes to form roots on the sloped ground, whereby it is possible to construct a remarkably strong block wall for seawalls and retaining walls.

<Examples> Examples of the present invention will be described in detail below with reference to the drawings.

The concrete block 1 of the present invention comprises a block body 2
It is characterized in that a tree-planting space 3 is formed in the.

The above-mentioned tree-planting empty part 3 is a trumpet shape that opens on the surface of the block body 2 and has a diameter that decreases from the upper end of the opening part toward the lower end part 4. A small-diameter communication hole 5 communicating with the back surface of the block body 2 is connected to the lower end portion 4 of the tree-planting space 3 described above. In addition, the tree-planting empty portion 3 and the above-mentioned communication hole 5 are inclined downward from the opening of the block body 2 toward the lower end portion 4, and are opened in the back surface portion of the block body 2.

In the embodiment shown in the drawings, two tree-planting cavities 3 are provided above and below the central portion of the block body 2, and the left and right side edges of the block body 2 are notched in the vertical half of the tree-planting cavities 3. The part 6 is formed vertically. Therefore, when the above-mentioned block main bodies 2 are continuously constructed on the left and right sides, the notch portions 6 on the side edges of the adjacent block main bodies 2 can be aligned to form the tree-planting empty portion 3 and the communication hole 5. However, the tree-planting cavities 3 formed in the block body 2 can be provided not only in the upper and lower two in the center but also at appropriate positions in the block body 2.

Since the concrete block 1 of the present invention basically has the above-mentioned configuration, when the concrete block 1 is constructed in an inclined shape along the slope of a riverbank or a mountain area, a concrete wall A is formed. At that time, due to the inclination of the concrete wall A, the tree-planting cavities 3 of the respective block bodies 2 and the tree-planting cavities formed by the notches 6 formed in the connecting portions of the adjacent block bodies 2 are positioned vertically upward. At the same time, the communication hole 5 and the communication hole formed by the notch 6 formed in the communication portion of the adjacent block main body 2 are located on the lower side in the vertical direction. Therefore,
It is possible to fill the inside of the cavities 3 for each tree planting and the notches 6 with soil and the like, and to naturally plant the saplings of the tree a without inclining them. It corresponds to the state.

Then, as the tree a grows gradually, the roots pass through the communication holes 5 and stretch greatly on the riverbank below the block and the ground on the slope, so that the revetment and retaining wall formed by each concrete block 1 and all blocks are firmly held Therefore, it does not collapse greatly due to the displacement or deformation of the ground.

In the above-mentioned embodiment, the surface of the block main body 2 on which the tree-planting cavities 3 are not formed remains concrete and is not planted. Therefore, another embodiment shown in FIG. 8 and FIG.
A plurality of ornaments 7 imitating a stone material are provided on the surface of the block body 2, and each ornament 7 is fixed by a surface layer portion 8 made of concrete or mortar. The ornament 7 naturally adapts the surface of the block body 2 to each other. It is a mode to do.

In the above-described embodiment, the ornamental tool 7 uses natural stone material or artificial stone material manufactured by, for example, kneading fine powder of natural stone and white cement powder with water, pouring the mixture into a mold, curing and hardening. Then, the lower surface is flattened and placed on the surface of the block body 2 so as not to cover the tree-planting vacant space 3, and the surface layer portion 8 is cast on the surface of the block body 2 to cure and harden it. The tool 7 may be firmly fixed. But,
The ornament 7 may be not only a stone material but also a tree pattern.

In this way, the block body 2 has a tree planting empty space 3
Since the surface of the concrete wall A is formed and the accessory 7 is appropriately attached to the surface of the concrete wall A,
In this case, since the tree a is planted in each of the tree-planting cavities 3 and the ornament 7 is provided on the surface of each block main body 2, the surface of the concrete wall A is naturally made more than the above-mentioned embodiment. Can be adapted.

In the other embodiments of FIGS. 10 and 11, the block main body 2 is provided with a plurality of tree-planting cavities 3 and notches 6 in the same manner as in the above-mentioned embodiments, and the surface of the block main body 2 is made of natural stone, a tree, or a log pattern. In addition, a part of the decoration material 9 that expresses other natural conditions is provided in an embedded state, and the remaining part of the decoration material 9 is three-dimensionally provided by projecting from the surface of the block body 2. .

According to the embodiment shown in the drawings, the decoration material 9 is a column shape imitating a log, but any decoration material imitating a natural situation, such as a decoration material imitating a natural cobblestone or a decoration material imitating a tree, can be used. Such an aspect may be used.

In the concrete block 1 described above, a part of the decorative material 9 is set so as to protrude into the mold (not shown) at the time of molding,
In addition, a projecting portion may be provided in the mold so as to form the tree-planting cavity 3, and concrete may be poured into the mold to cure and cure. However, after molding the block main body 2 in which a large number of recesses into which a part of the decorative material 9 can be inserted in advance are formed with concrete and curing and curing, the part of the decorative material 9 is inserted into each of the above-mentioned recesses. You may fix it.

Therefore, in the concrete block 1 according to the above-mentioned embodiment, not only the tree-planting vacant space 3 is formed, but also a large number of decorative materials 9 are integrally provided on the surface and a part thereof is projected, so that a three-dimensional decorative pattern is obtained. Can be presented.

Block wall A by the concrete block 1 described above
, The front of the block wall A has a space 3 for each tree planting.
The tree a planted in 1 is propagated, and a large number of decoration materials 9 partially project from each concrete block 1.
Therefore, the form of the decorative material 9 may be selected according to the building location of the block wall A. For example, when the block wall A is constructed as a retaining wall in a mountainous area, if the decorative material 9 of each concrete block 1 is in the form of logs or trees, and if the block wall A is constructed for river bank or seaside protection,
If the decorative material 9 of each concrete block 1 is made of natural stone or artificial stone, it can be sufficiently adapted to the natural environment.

Further, although the building block of the present invention may be used on the entire surface of the block wall such as the seawall and the retaining wall, it may be used as a part and the other part may be an ordinary block.

It should be noted that the above-mentioned embodiment of FIGS. 8 and 9 and the tenth embodiment
In the embodiment shown in FIGS. 11 and 12, the reference numerals not described are the same as those in the embodiment shown in FIGS. 1 to 4, and their explanations are omitted.

The building blocks of the present invention have been described above based on the embodiments of the drawings, but the present invention is not limited to the above-mentioned embodiments, and how is it modified unless the configuration described in the claims is changed. But it can be done.

<Effects of the Invention> In short, according to the present invention, the block body has a hole for tree planting formed in a diagonal direction with respect to the surface facing the back side and opening to the back side, and a diameter smaller than the tree planting space. While providing a communication hole that communicates with the lower end of the tree-planting cavity and opens to the rear side, the side edge of the block body has the same inclination as the tree-planting cavity and the communication hole and the tree-planting cavity. And a cutout portion having a half shape of the communication hole is formed, and in a state where the block body is installed in an inclined shape along a slope, the tree-planting space is installed so as to open toward the upper side in the vertical direction. In addition, while the communication hole is installed toward the lower side in the vertical direction, by aligning the block main body, each notch of the side edge of the adjacent block main body is matched, and the empty space for tree planting and Trees in the empty space for planting the matched notches Along with making it possible to plant trees in the vertical direction,
It is characterized in that the root of the planted tree passes through the communication hole and the communication hole of the notched portion and stretches into the ground.

Therefore, it becomes possible to plant the tree saplings without tilting them in the tree planting cavities and the tree planting cavities in the cutouts, and the trees grow in a natural state and the retaining walls of the blocks that are dead landscape are natural. Since it can adapt to the environment and landscape, it is possible to construct a revetment wall and retaining wall that are rich in variety and decorative, and do not impair the natural landscape. Further, in the present invention, since the tree-forming vacant portion is formed in the adjacent portions of the block main bodies that are adjacent to each other on the left and right, it is possible to plant the tree saplings without inclining them, so that the trees and the like are almost entirely formed on the block wall. Can be overgrown to correspond to the surrounding landscape in a visually natural state. Moreover, since the communication hole that communicates with the sky for tree planting opens vertically downward to the back side of the block body, when the tree grows it can root up to the riverbank or the ground of the slope, The strength of the block wall can be remarkably increased, it will not crack or collapse, and especially when trees grow large in the adjacent part of the block body, roots will deeply extend to the ground behind the block wall. The adjacent part of the block body can be reinforced, which is of high practical value.
