Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a construction block that can be used, for example, as a seawall or as a retaining wall.

<Prior art> As is well known, blocks for retaining walls for seawalls or for building residential land, roads, and tracks are made of concrete, and the surfaces of the blocks are hardly treated, so it is difficult to build seawalls or retaining walls. If built sideways, the landscape will be desolate and will seriously disrupt the natural environment and landscape. Furthermore, if a block wall is constructed for a long period of time, it may gradually shift or crack due to natural topographical changes, vibrations, etc., and in extreme cases, there is a risk of collapse.

<Problem to be solved by the invention> Furthermore, decorating the surface of a concrete block in a state similar to the natural environment would be extremely expensive, so the side bottom cannot be used when constructing a large-scale seawall or retaining wall. Furthermore, when a seawall or retaining wall cracks or collapses due to natural phenomena, repair work is extremely troublesome.

Therefore, there is a need for construction blocks that are naturally adaptable when constructed as bank protection or retaining walls, can be mass-produced at low cost, and are extremely strong.

<Means for Solving the Problems> The present invention has been proposed in view of the above, and includes a tree-planting hole that is oriented approximately vertically in a state where the block body is installed in an inclined manner with an opening on the surface of the plot body. By planting trees in the above-mentioned empty space, the natural environment and scenery will not be harmed, and the trees will gradually grow and spread their roots on slopes, etc., making it possible to create extremely strong bank protection and retaining structures. You can build wall blocks.

<Example> Examples of the present invention will be described in detail below based on the drawings.

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

In the embodiments shown in FIGS. 1 to 4, the above-mentioned tree-planting cavity 3 opens on the surface of the block body 2 and has a trumpet shape whose diameter decreases from the upper end of the opening toward the lower end 4. and,
At the lower end 4 of the tree-planting space 3, a block body 2 is provided.
A small-diameter communication hole 5 communicating with the back surface of the device is made continuous. Also,
The tree-planting cavity 3 and the communication hole 5 described above are inclined downward from the opening of the block body 2 toward the lower end 4.

In the embodiment shown in the drawings, two of the above-mentioned tree-planting spaces 3 are provided above and below the central part of the block body 2, and on the left and right side edges of the block body 2, a vertical half of the tree-planting space 3 is cut out. Sections 6 are formed at the top and bottom. Therefore, when the above-mentioned block bodies 2 are continued in the left and right directions, the notches 6 on the side edges of the adjacent block bodies 2 match to form the tree-planting cavity 3 and the communication hole 5. However, block body 2
The tree-planting spaces 3 to be formed are not only the two above and below the center;
It can be provided at an appropriate position on the block body 2.

Since the concrete block 1 of the present invention basically has the above-mentioned configuration, when this concrete block 1 is constructed in an inclined shape along a river bank or a slope in a mountainous area, a concrete wall A is formed. Due to the inclination of the tree-planting space 3 of each block body 2, and the space formed by the notch 6 formed at the connecting part of the adjacent block bodies 2, the space is oriented approximately vertically (therefore, each tree-planting space 3 is oriented in the vertical direction. Part 3
The hollow space formed by the cutout 6 can be filled with earth and sand to plant a plant a, and this plant a is made of concrete! !
To make the surface of A compatible with the natural environment.

As the plant A gradually grows, its roots pass through the communication hole 5 and spread over the riverbank or slope, which will firmly hold each concrete block l, and there is a possibility that it will collapse due to displacement or deformation of the ground. Less is.

In the above-described embodiment, the block body 2 does not have the tree-planting space 3.
The surface is concrete. Therefore, although the plant A may be planted in a part of the concrete wall A, the other part of the surface of the block body 2 remains almost concrete. Example is block body 2
A plurality of decorative tools 7 imitating stone are provided on the surface of the
is fixed with a surface layer 8 made of concrete or mortar, and the surface of the block body 2 is adapted to naturally conform to the decoration 7.

In the embodiments described above, the decorative tool 7 is made of natural stone or artificial stone produced by mixing fine natural stone powder and white cement powder with water, pouring the mixture into a mold, and curing and hardening the mixture. Then, the lower surface is made flat and placed on the surface of the block body 2 so as not to cover the tree-planting space 3.
A surface layer 8 may be cast on the surface of the block body 2 to provide a curing effect, and each decorative tool 7 may be firmly fixed. However, the decorative tool 7 may be made of not only stone but also a tree pattern.

In this way, the block body 2 has a tree-planting space 3 formed therein, and the decorations 7 are appropriately placed on the surface and fixed at the surface layer 8, so when constructing the concrete wall A. Since the plants A are planted in each of the tree-planting spaces 3 and the decorations 7 are provided on the surface of each block body 2, the surface of the concrete wall A can be made to correspond to nature even more than in the above-mentioned embodiments. can.

In the embodiment shown in FIGS. 10 and 11, the block body 2 is provided with a plurality of hollow areas 3 for planting trees as in the previous embodiment, and the surface of the block body 2 is covered with natural stones, trees, log patterns, and other natural conditions. A part of the decorative material 9 representing the above is provided in a buried manner, and the remaining part of the decorative material 9 is provided three-dimensionally by protruding from the surface of the block body 2.

According to the embodiment of the drawing, the decorative material 9 has a cylindrical shape imitating a log, but it can be any decorative material that can express a natural situation, such as a decorative material imitating a natural cobblestone or a decorative material imitating a tree. It may also be in this form.

The above-mentioned concrete block 1 is made of decorative material 9 during molding.
A part of the concrete is set so as to protrude into the formwork (not shown), and a protrusion is provided in the formwork so that a tree-planting cavity 3 is formed, and concrete is poured into the formwork. It is sufficient to cure and harden it. However, the block body 2 is formed with concrete in which a number of recesses into which a part of the decorative material 9 can be inserted is formed on the surface in advance, and after curing and hardening, a part of the decorative material 9 is inserted into each of the recesses. You can also fix it.

Therefore, the concrete block l according to the above-mentioned embodiment not only has a tree-planting cavity 3 formed therein, but also has a large number of decorative materials 9 integrally provided on its surface, some of which protrude, resulting in a three-dimensional decorative pattern. can be exhibited.

When a block wall A is constructed using the concrete blocks 1 described above, the plants a planted in each tree-planting space 3 will propagate on the front surface of the block wall A, and decorative materials 9 that partially protrude from each concrete block 1 will grow. There are many. Therefore, the decorative material 9 corresponds to the construction location of the block wall A.
All you have to do is select the mode. For example, if the block wall A is to be constructed as a retaining wall in a mountainous area, the decorative material 9 of each concrete block 1 should be in the form of a log or tree, and if the block wall A is to be constructed as a revetment on a river bank or seaside, If the decorative material 9 of each concrete block l is made of natural stone or artificial stone, it can be sufficiently adapted to the natural environment.

Further, the construction block of the present invention may be used for the entire surface of a block wall of a seawall or a retaining wall, but it can also be used for one part and the other parts made of ordinary blocks.

In the embodiments shown in FIGS. 8 and 9 and the embodiments shown in FIGS. 10 and 11 described above, unexplained symbols have the same configuration as in the embodiments shown in FIGS. 1 to 4. The explanation will be omitted from here.
