Description

[Detailed description of the invention] Industrial application field The present invention relates to a vegetation block that can be used to grow plants in the gardens of houses, schools, parks, etc., and can also be used as fences and median strips of roads.

Purpose of the Idea Despite the importance placed on urban greening in recent years, the current situation is that it is not possible to secure enough gardens, parks, and other green areas for residential buildings due to soaring land prices. In view of this, the present invention was devised to provide a new vegetation block that effectively utilizes vertical space, has excellent aesthetics and workability, and is structurally stable. .

Structure of the invention The present invention is a precast concrete structure in which a pair of opposing side walls and a pair of end walls are integrally molded into a substantially quadrilateral shape.
It consists of several stacked parts made of wood, and the end wall of each part except the top one is higher than the side wall. This vegetation block is characterized in that the end wall of the upper part is placed on top for support, and that the width of each part becomes smaller as the part goes up.

The number of stages and detailed shape and dimensions of the parts will depend on the concrete strength, amount of reinforcing steel, purpose of the vegetation block,
The decision shall be made taking into account the scale, design, angle of repose of the soil, etc.

First Embodiment Figures 1 to 3 show a vegetation block 1 according to a first embodiment of the present invention, with Figure 1 being a perspective view, Figure 2 being a longitudinal cross-sectional view, and Figure 3 showing how it is used. FIG.

Vegetation block 1 consists of 1st stage part 2, 2nd stage part
It consists of a third part 3 and a third stage part 4. Each part is made of precast concrete, including a pair of opposing side walls 2a, 3a, 4a and a pair of end walls 2b, 3b, 4b.
It is integrally formed into a substantially quadrilateral shape. As shown in FIG. 3, the width of the parts in each stage becomes smaller as the parts go up. The side walls 2a, 3a, and 4a have an outwardly inclined and overhanging shape to increase the area for planting plants and to efficiently receive sunlight. The first end wall 2b and the second end wall 3b are formed higher than the side walls 2a and 3a, respectively.
Since the width of the parts is smaller in the upper tier, a window-like space is created between the upper and lower side walls of each tier, and by filling this with earth and sand, it becomes the soil surface for planting plants. . In this case, it is necessary that the angle α of the soil filling surface does not exceed the angle of repose of the soil to be filled. When stacking parts, stack the parts on the bottom.
The gable wall of the upper part is placed on the gable wall of the upper part for support. That is, as shown in Figure 2, the first
The second tier end wall 3b rests on the tier end wall 2b, and the third tier end wall 4b rests thereon. This can be said to be a sufficiently stable structure due to the weight of each part, the weight of the earth and sand filled, the internal friction angle, and the adhesive strength. The reason why the end walls 2b, 3b, and 4b are formed to become thicker toward the bottom is to facilitate demolding of the mold during manufacturing.

As shown in FIG. 3, if the inside of the vegetation block 1 is filled with earth and sand and planted with various plants, the planted area will be much larger than the area occupied by the block. It also has good rainwater absorption efficiency, and water that cannot be absorbed by the upper stage is sequentially sent to the lower stage and absorbed.
Construction is extremely simple, just stacking factory-produced parts on a stable base of soil, concrete, etc.

Second Embodiment Figures 4 to 6 show a second embodiment of the present invention.
A vegetation block 10 suitable for use in conjunction as a road median strip, sound insulating wall, etc. is shown, and FIG. 4 is a sectional view in the width direction, FIG. 5 is a sectional view in the longitudinal direction showing the connected state, and FIG. 6 is a sectional view in the longitudinal direction. FIG. 2 is a perspective view showing the state of use.

The vegetation block 10 has three stages of parts 11, 12,
Each part consists of a pair of opposing side walls 11a, 12a, 13a and a pair of end walls 11.
b, 12b, and 13b are integrally molded into a substantially quadrilateral shape.

The features of this embodiment are, firstly, as shown in FIG. The step gable wall 13b is formed lower than the side wall 13a. For this reason, as shown in FIG. 6, the gable wall is completely hidden from the planting surface, increasing the planting area and providing a superior design.

Second, bolt connection holes 14 and iron plate recesses 15 are provided in the end wall. As shown in Fig. 5, the four parts (top, bottom, left and right) are integrated by tightening the connecting bolts 18 through the iron plate 17, and the whole part is made into four parts, making it extremely stable. It becomes a structure.

Thirdly, drill holes 1 in the gable walls of the first and second stages.
6 was installed to integrate the earth and sand to be filled and to allow plant roots to spread freely.

Effects of the Invention As mentioned above, the vegetation block of the present invention has a wide area for planting plants, makes effective use of space in the height direction, is structurally stable, and has good construction properties. Moreover, by using it for road median strips and sound insulation walls, it can enhance the aesthetic appearance, completely block light from headlights, etc., and improve the sound insulation effect.
