Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a large stepping stone block that can cover the bare ground or road surface with a surface block having the same unit area and green the entire surface.

[0002]

[Prior art]

 Conventionally, there has been a concrete block having a structure in which a bare ground is covered with a block, that is, a so-called greening block. For example, Japanese Unexamined Patent Publication No. 9-170221 is a technology having the following general configuration. That is, `` a plurality of pseudo concrete stones with a normal concrete layer on the upper layer are arranged so that the overall shape is substantially square by the four corner pseudo stones, and a space for vegetation is formed between each pseudo stone, By connecting the multiple artificial stones with the reinforcing steel that penetrates them and the porous concrete connecting part that covers the reinforcing steel, it prevents the plants planted in the space from drying and dying due to root rot. '' Technical content.

[0003] However, the configuration of the prior art described above is as follows: (1) providing a normal concrete layer on the upper layer of porous concrete as a pseudo stone; (2) rebar penetrating the pseudo stone; In order to manufacture the unit pseudo stone, it is necessary to connect by a porous concrete connection part that covers the reinforcing steel. (3) The planting space (groove) itself is provided with a special hole such as a small hole. (4) To bind adjacent pseudo-stone units, bind the four corners with connecting metal fittings, and as an effect, use porous concrete for pseudo-stone. It claims that it would be possible to have plant roots penetrate into fake stones. Furthermore, at the time of actual construction, as described above, it is necessary to artificially provide connecting rings at the four corners and bind them with connecting fittings.

[0004] Further, in all of the above and other related arts, the unit block is at most a relatively small one of about 450 mm square at most.

[0005]

[Problems to be solved by the invention]

 All of these prior arts require extraordinarily complicated configurations, or if the unit block is relatively small and a large space is covered with these conventional unit blocks, the surface image is too fine and the overall image is too small. It had the disadvantage of not being able to grasp it.

[0006] The present invention has been made in view of the above-mentioned problems. In addition to the fact that the structure itself is not complicated, the man-hour required for construction is not large, the block does not easily float after construction, and It provides a large stepping stone block with large irregularities that is maintained and does not impair the overall image, and plants such as grass and tamaryu are planted in the planting pot arranged in the middle of the large stepping stone block. The purpose is to provide a large-sized stepping stone block with a new structure that can be greened as a whole and look more natural.

[0007]

[Means for Solving the Problems]

 The large stepping stone block of the present invention has a front shape of preferably a substantially rectangular shape of 90 to 150 cm × 90 to 150 cm and a thickness of preferably about 10 cm to 20 cm, or concrete with reinforced concrete. The front side is formed so that the side walls correspond to the side walls of the grass planting block adjacent to the grass planting block, and the surface is planted with rock-like protrusions, preferably 5 to 20 cm, with large unevenness. The gist is configured such that a large number of small holes having a diameter of preferably 2 to 10 cm are formed in the planting groove. If the surrounding environment is inferior, for example, if the wind is extremely strong and the unit block is lifted up after construction, the thickness of the unit block may be increased to the necessary extent. It suffices to add an application, and it is not necessary to provide a complicated configuration in advance as in the above-described prior art.

Further, the side wall 4 may be formed in a straight rectangular shape. The large stepping stone block with the above configuration is laid vertically and horizontally on the surface of the ground, and the holes and planting ditches are filled with rooting soil or rooting material to plant and grow plants such as grass and tamaryu. Things.

[0009]

Embodiment 1 Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a front view of a large unit stepping stone block, FIG. 2 is a right side view of the same, FIG. 3 is a sectional view taken along line AA in the front view, and FIG.

The grass planting block 1 has a substantially rectangular front surface of 90 to 150 cm × 90 to 150 cm, and is made of concrete having a thickness of 10 cm to 20 cm or concrete with a reinforcing bar. The substantially square front is configured such that the side walls 2 are adjacent to the side walls 2 of the grass planting block 1 adjacent to each other. With this structure, when arranged vertically and horizontally, they can be arranged without gaps.

On the surface of the grass planting block 1, rock-like projections 3, 3... And a 5 to 20 cm planting groove 4 are formed by large irregularities, and the planting groove 4 has a diameter of 2 to 10 cm. A large number of small holes 5, 5,...

The grass planting block 1 having the above structure is laid vertically and horizontally on the surface of the ground, and small holes 5, 5,... The root material is filled, and plants 6 such as shiva and tamariyu are planted and prospered. The root of the plant 6 grows and reaches the ground below from the stoma 5 to promote the growth of the plant 6.

[0013]

Embodiment 2 FIG. 5 shows another embodiment in which the shapes of the rock-like projections 3 and the side walls 2 are different. In this embodiment, the rock-like convex portion 3 constitutes one convex portion together with the adjacent planting block 1. Therefore, when the grass planting block 1 is laid, the rock-like convex portion 3 has a structure that is not divided for each block, and it looks more natural.

[0014]

Third Embodiment FIG. 6 shows an embodiment in which the side wall 2 is straight. That is, the side walls are formed in a 90 to 150 cm square shape by the straight side walls, and can be laid closely vertically and horizontally. In the overall structure after the construction, rock-like irregularities 3 appear on the front, and the seams are not emphasized much.

[0015]

[Effect of the invention]

 As described above, the large stepping stone block of the present invention is preferably provided with relatively large rock-like irregularities on a concrete block having a thickness of about 1.5 meters and a thickness of 20 cm, and having planting grooves and small holes formed therein. Because of the structured structure, the blocks do not float easily after construction and are not only stably maintained, but also the structure itself is much simpler than the conventional one.

[0016] Further, a large stepping stone block having a large unevenness which does not impair the whole image is constituted, and plants such as shiva and tamariyu are planted in a planting groove arranged in the middle of the large stepping stone block. It has features such as greening of the entire plant to make it look more natural, and the effects obtained by implementing the present invention are extremely large.
