JP2001011809A - Board block for sidewalk, and sidewalk using the same - Google Patents

Abstract

PROBLEM TO BE SOLVED: To easily produce a stone pavement sidewalk by smoothly arranging natural stones or imitation stones on the surface of a trapezoid concrete block, and to use the same blocks for a curved portion and a linear portion of the sidewalk. SOLUTION: Sidewalk board blocks 10 which are mass-produced in a factory is employed, and a surface for placement is smoothed, whereby the sidewalk board blocks 10 are mounted thereon. In this case, if a sidewalk 30 linearly extends, the blocks 10 are arranged in an alternately inverted manner with long sides 1c of the respective blocks 10 being connected together, and a short side 1a of the block 10 is aligned to a short side 1b of the adjacent block 10. If the sidewalk 30 is curved, the short sides 1a, 1b are arranged on the same side of the sidewalk 30, which enables formation of a curved portion. Further, a joint of the blocks 10 and depressions among natural stones 2 may be filled with sand or joint gravel to make the height flush, which leads to easy walking. In this manner, the sidewalk board blocks 10 can be mass-produced in the factory, and only one type of a form for production is required, which leads to improved productivity of the board blocks.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sidewalk plate block used for manufacturing a cobblestone sidewalk in a hill or a mountain path, and a sidewalk using the same.

[0002]

2. Description of the Related Art Cobblestone sidewalks in hills have many curved portions. Conventionally, natural stones are manually arranged one by one on a laid portion, and the upper surface thereof is adjusted to be flat.

[0003]

However, the work of arranging natural stones in a plane is time-consuming and requires a large number of people and a construction period.

The present invention has been made in view of the above circumstances, and an object of the present invention is to make it possible to easily manufacture a cobblestone sidewalk using a concrete block manufactured at a factory, and furthermore, to make a curved portion of the sidewalk straight. Another object of the present invention is to provide a sidewalk board block that can use the same block and a sidewalk using the same.

[0005]

The invention according to claim 1 is characterized in that natural stone or pseudo stone is arranged in a plane on the surface of a trapezoidal concrete block.

The invention of claim 2 is characterized in that natural stone or pseudo stone is exposed on the upper surface and the side surface of the long side of the concrete block.

The invention of claim 3 is characterized in that a plurality of trapezoidal sidewalk board blocks are arranged so as to be in contact with their inclined side surfaces.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A sidewalk board block 10 according to a first embodiment of the present invention will be described with reference to FIGS.

First, in FIGS. 1 to 3, the concrete block 1 has a trapezoidal shape, and one short side 1a is formed larger than the other short side 1b side.

On the upper surface of the concrete block 1, a plurality of natural stones 2 are arranged in a plane. The upper surfaces of these natural stones 2 are formed almost flat. Note that a pseudo stone may be used instead of the natural stone 2.

FIGS. 4 (a) and 4 (b) show a sidewalk board block 11 according to a second embodiment, which differs from the sidewalk board block 10 in that natural stones 2 disposed on the surface thereof are provided on the sidewalk. The plate block is smaller than the plate block 10, for example, using a gravel or the like.

Next, a sidewalk 30 according to a third aspect will be described with reference to FIGS. The sidewalk 30 uses the sidewalk board block 10 or the sidewalk board block 11 mass-produced in a factory. That is, first, the laying surface G is flattened, and the sidewalk board block 10 or the sidewalk board block 11 is placed thereon. That is, when the sidewalk is straight, the sidewalk board blocks 10 are alternately arranged so that the inclined side surfaces, that is, the long sides 1c are in contact with each other, as shown in FIGS. In this case, the short side 1a of the sidewalk board block 10 is arranged to be continuous with the short side 1b of the adjacent sidewalk board block 10.

When the sidewalk has a curved shape, a curved portion can be formed by disposing the short side 1a and the short side 1b on the same side of the sidewalk 30, as shown in FIG. The connecting portion of the sidewalk board block 10 or the concave portion between the natural stones 2 (FIG. 6)
It is convenient for walking if sand and joint gravel are put in the A section shown in Fig. 1 and the heights are made uniform. The lengths of the short side 1a and the short side 1b may be appropriately set according to the radius of curvature of the sidewalk.

The sidewalk board block 10 can be produced in large quantities at a factory and requires only one type of formwork, so that the productivity can be significantly improved.

Further, the cobblestone sidewalk 30 can be formed only by flattening the laying surface G and arranging the sidewalk board blocks 10 thereon, so that it is necessary to arrange natural stones by hand as in the prior art. There is no need to adjust the flatness of the plane. Also, the sidewalk board block 10 includes a sidewalk 30.
Since the same sidewalk board block 10 can be used for both the straight portion and the curved portion, there is an effect that the laying work is significantly simplified. Although the natural stone 2 is provided on the surface of the sidewalk 30, the same effect can be obtained by using a concrete block 1 having a flat surface.

FIGS. 8 and 9 show a sidewalk board block 20 according to a third embodiment of the present invention, which is used in a step portion. The difference from the sidewalk board block 10 is that the natural stone 2 is also exposed on the upper surface of the concrete block 1 and the side face of the long side portion 1c, and the entire height is formed larger than the sidewalk board block 10. I have.

As shown in FIG. 10, this sidewalk board block 20 is located between two sidewalk board blocks 10 arranged on a straight or curved sidewalk, ie, a lower sidewalk board block 10.
When it is arranged at an intermediate portion between the upper sidewalk board block 10 and the upper sidewalk board block 10, a staircase can be formed. Note that B shown in FIG.
The portion may be backfilled with soil or concrete. Moreover, since the natural stone 2 is also exposed on the side surface of the long side 1c, the scenery of the stone pavement can be maintained.

In the sidewalk board block 20 of this embodiment, the natural stone 2 is exposed on both side surfaces of the long side portion 1c. However, the present invention is not limited to this, and the natural stone 2 is exposed on at least the front surface of the stairs on the C side shown in FIG. It would be fine. The third embodiment also has the same effects as the first embodiment.

[0019]

In the sidewalk board block according to the first and second aspects of the present invention, natural stones or pseudo stones are arranged in a plane on the surface of a trapezoidal concrete block. In addition, since only one type of frame is required, the productivity can be significantly improved.

If natural stone or artificial stone is exposed on the upper surface and the side surface of the long side of the concrete block, an excellent effect that a staircase can be formed can be obtained.

In the sidewalk according to the third aspect of the present invention, the cobblestone sidewalk can be formed only by flattening the laying surface and arranging the sidewalk board blocks thereon, so that the laying operation is significantly simplified. Further, since the same sidewalk board block 10 can be used for both the straight portion and the curved portion of the sidewalk, there is an effect that productivity can be remarkably improved.
