Abstract

PROBLEM TO BE SOLVED: To provide a large stepping-stone block capable of preventing the block from floating simply after the construction, maintaining it stably, and preventing an image of the whole block from being impaired and having large recessed and projecting parts. SOLUTION: Side walls 2 and the recessed and projecting parts of the plant planting block 1 which is formed by concrete having a substantially rectangular front shape of 90 to 100 cm×90 to 100 cm and a thickness of about 10 cm or reinforced concrete and in which the side walls 2 are adjacent on the front are constituted so as to correspond mutually. Rocklike projecting parts 3, 3,... and a planting channel 4 of 6 to 10 cm are constituted by large recessed and projecting parts on a surface thereof, and many small holes 5, 5,... having a diameter of 3 to 5 cm are drilled in the planting channel 4. These blocks are provided and arranged lengthwise and crosswise on a surface of the ground, and soil for taking root or a material for taking root is filled into the small holes 5, 5,... and the planting channel 4 to plant plants 6 such as brushwood and Ophiopogon japonicus so that they grow fully.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a large stepping stone block for covering exposed ground or road surface with a surface block having the same unit area.

[0002]

2. Description of the Related Art Conventionally, there has been a concrete block having a structure in which a bare ground is covered with a block. However, in general, they were 450 mm square or 300 mm square at most, and the surface patterns were often artificial and fine.

[0003]

For this reason, when a large space is covered with the block, the surface pattern is too fine to grasp the entire image, and the block floats after construction, resulting in a problem of aesthetic deterioration. Had.

[0004] The present invention has been made in view of the above problems, and a large stepping stone having large irregularities which does not easily float after construction and is stably maintained without damaging the entire image. The purpose of this project is to provide a large stepping stone block with a new structure that can provide a block and plant flowers such as grass and tamaryu in a planting pot arranged in the middle of the large stepping stone block and make it look more natural. is there.

[0005]

The large stepping stone block of the present invention has a front shape of preferably 90 to 100 cm × 9.
It has a substantially rectangular shape of 0 to 100 cm, and is preferably formed of concrete or reinforced concrete having a thickness of about 10 cm. In addition, a rock-like convex part with large unevenness and a planting groove of preferably 6 to 10 cm are formed on the surface, and the planting groove has a diameter of preferably 3 to 5 cm. The main point is that many small holes are formed.

[0006] The side wall 4 may be formed in a straight rectangular shape. Large stepping stone blocks of the above configuration are laid vertically and horizontally on the surface of the ground, and small holes and planting grooves are filled with soil for rooting or rooting material to plant plants such as grass, tamaryu, etc., and thrive. Things.

[0007]

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

The front of the grass planting block 1 is 90-100.
It has a substantially rectangular shape of 90 cm to 90 cm, and is made of concrete having a thickness of about 10 cm or concrete with reinforced steel. The substantially square front is the side wall 2.
Are configured so that the side wall 2 of the adjacent grass planting block 1 and the unevenness correspond to each other. With this structure, when they are 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 large number of small holes 5 having a diameter of 3 to 5 cm are formed in the planting groove 4.

The grass planting block 1 constructed as described above 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 grass and tamariu are planted and prosperous. The root of the plant 6 grows and reaches the ground below from the stoma 5 to promote the growth of the plant 6.

[0011]

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.

[0012]

Embodiment 3 FIG. 6 shows an embodiment in which the side wall 2 is straight. In other words, it is configured to have a square shape of 90 to 100 cm by the linear side walls, and can be laid closely vertically and horizontally. In the overall configuration after the construction, the rock-like irregularities 3 appear on the front surface, and the seams are not emphasized much.

[0013]

As described above, the large stepping stone block of the present invention is preferably provided with relatively large rock-like irregularities in a concrete block of about 1 meter square and 10 cm thick, and a planting groove and a small groove. Since the structure has the holes, the blocks do not easily float after construction and are stably maintained.

Further, a large stepping stone block having large irregularities which does not impair the overall image is constructed, and plants such as grass and tamaryu are planted in planting grooves arranged in the middle of the large stepping stone block, thereby providing a more natural Therefore, the present invention has an extremely large effect.
