[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a sidewalk boundary structure at a boundary between a road and a sidewalk.

[0002]

[Prior art]

 Conventionally, as shown in FIG. 3, the sidewalk boundary structure B has a structure in which an access block 52 and a side gutter block 51 are interposed between a sidewalk 57 and a sidewalk 58. It is designed to allow easy entry of wheelchairs and wheelchairs.

[0005] Specifically, the sidewalk boundary structure B will be described separately for the sidewalk 57 side and the sidewalk 58 side.

[0004] First, as for the structure on the sidewalk 57 side in the sidewalk boundary structure B, as described above, the base material layer 55 in which the base material is laid on the lowermost layer, and the base concrete formed by injecting concrete thereabove. The structure is such that a layer mortar layer 53 is formed by applying a layer mortar on the layer 54 and a mortar block 52 is further laid thereon. Then, the base material layer 55, the foundation concrete layer 54, the mortar layer 53, and the roadway-side end face of the entry block 52 are brought into close contact with the gutter block 51.

[0005] The entry block 52 is made of an elongated, elongated, rectangular-shaped concrete prism having a rectangular cross-section, which is rounded off by cutting off the corners of the upper corners on the roadway side, so that wheelchairs, bicycle wheels, and people can enter. The structure is easy and the strength can be increased, and there is little damage such as chipping.

In addition, the laying mortar layer 53 has the same width as the laying block 52 and the mortar layer 53 in order to adhere and fix the entry block 52 to the foundation concrete layer 54. The base material layer 55 is extended about 5 cm further to the sidewalk side than the foundation concrete layer 54 to the sidewalk 57 side of the mortar layer 53 and the foundation material layer 55 to stabilize and strengthen the sidewalk boundary structure B.

On the other hand, the structure on the side of the roadway 58 will be described. On the side of the roadway 58, a culvert type gutter block 51 is provided, and the gutter block 51 becomes a water passage substantially at the center in a cross-sectional view. It is made of elongated concrete having a hollow portion. The upper surface of the gutter block 51 is inclined so that the side of the roadway 58 is slightly higher than the side of the sidewalk 57, and the lower side surfaces are chamfered to form the sidewalk 57 side. A cutout 51a having a rectangular cross section is formed in the upper surface edge 1b over the entire length of the edge 1b.

At the boundary of the sidewalk, a groove formed by a notch 51 a is formed between the side groove block 51 and the entry block 52, and concrete is poured into the groove to be continuous with the upper surface of the side groove block 51. A flat concrete casting portion 56 is formed, and the entry block 52 is strongly adhered and fixed to the roadway 58 side.

[0009] The embedding depth of the entry block 52 is usually determined by the step in the entry portion, that is, the surface of the concrete placing portion 56 formed in the side groove block 51 and the upper surface of the adjacent entry block 52. The height difference is set to a predetermined size. The standard value is about 2cm.

[0010]

[Problems to be solved by the invention]

 However, in the above-described conventional sidewalk road boundary structure, concrete must be cast at the construction site in order to form the concrete casting surface 56 between the entry block 52 and the gutter block 51. Cracks occur at the bonding surface between the block 52 and the concrete placing portion 56 and between the concrete placing portion 56 and the gutter block 51, and the entry block 52 sinks due to the separation of the entry block 52 and the gutter block 51.・ There was a risk of causing irregularities.

[0011] Furthermore, not only the aesthetic appearance is impaired by the cracks, but also the soil is put into the cracks, and the seeds of the weeds fly into the cracks and germinate, so that the aesthetic appearance is lost, and it takes time to remove the weeds. Would.

Moreover, when the concrete is to be poured on site as described above, the steps at the part entering the sidewalk are maintained at, for example, steps conforming to a predetermined law, and the work is carried out so that there is no unevenness. It is not easy.

[0013]

[Means for Solving the Problems]

 Therefore, in order to solve the above-mentioned problems, in the present invention, a pedestrian road boundary block is disposed via a gutter block disposed on the road side, and the foundation is arranged below the pedestrian road boundary block in order from the lowest layer. In the pedestrian road boundary structure consisting of laminated materials, foundation concrete and mortar, a notch is formed along the entire length of the upper edge of the side gutter block on the side of the sidewalk, and the notch is formed in the notch. The edges of the roadway boundary block are overlapped and overlapped so that the inner wall surface of the notch and the outer wall surface of the pedestrian road boundary block are in close contact with each other, and the lower edge of the pedestrian road boundary block corresponds to the notch. A notch for engagement is formed at an edge, and a side groove block and a pedestrian road boundary block are arranged in a state where both notches are engaged with each other. is there.

The present invention is also characterized by a pedestrian road boundary structure in which the step between the gutter block and the pedestrian road boundary block is 1 to 3 cm.

[0015]

[Embodiment of the invention]

 In the present invention, a pedestrian road boundary block is arranged via a gutter block disposed on the road side, and under the pedestrian road boundary block, a base material, a foundation concrete, and a floor mortar are laminated in order from the lowest layer. In the pedestrian road boundary structure, a notch is formed along the entire length of the upper edge of the side groove block on the side of the pedestrian, and the edge of the pedestrian road boundary block is overlapped with the notch and overlapped. The inner wall surface of the notch and the outer wall surface of the pedestrian road boundary block are in close contact with each other, and an engagement notch is formed at the lower edge of the pedestrian road boundary block so as to correspond to the notch. In addition, the sidewalk block and the pedestrian road boundary block are arranged in a state in which the notches are engaged with each other, thereby providing a pedestrian road boundary structure.

[0016] By adopting such a boundary structure, it is possible to obtain a strong boundary structure that is unlikely to cause cracks, prevents subsidence and unevenness of the pedestrian road boundary block, is durable, and has an aesthetic appearance. It has an effect that can be maintained for a long time.

[0017] Furthermore, since it is not necessary to cast concrete to bond and fix the gutter block and the sidewalk boundary block, the number of working steps can be reduced and the cost can be reduced.

Further, since the side gutter block and the sidewalk boundary block are arranged in a state where the notches formed in both blocks are engaged with each other, the effective width of the sidewalk is equal to the length of engagement in the entering direction. And the amount of laying mortar, foundation concrete and foundation materials to be laid below the pedestrian road boundary block was reduced, which enabled cost reduction.

In the above-described sidewalk boundary structure, it is preferable that a step between the side gutter block and the sidewalk boundary block is 1 to 3 cm.

The step between the side gutter block and the pedestrian road boundary block can be freely adjusted by the degree of engagement between the notch of the gutter block and the notch of the pedestrian road boundary block. Further, by setting the step within the above-mentioned dimensions, it is possible to easily cope with, for example, the standard value of the step in the Traffic Barrier Free Law of the Ministry of Land, Infrastructure, Transport and Tourism.

The explanation is made assuming that it has been applied.

The basic structure of the pedestrian boundary structure A according to the present embodiment shown in FIGS. 1 and 2 is the same as that of the conventional pedestrian boundary structure B shown in FIG. The description will be omitted, and description of other structures will be omitted.

That is, the gist of the pedestrian road boundary structure A according to the present embodiment is that the entry block 2 as the pedestrian road boundary block is disposed via the gutter block 1 disposed on the road 7 side, and Underneath the insert block 2, a base material 5, a base concrete 4, and a mortar 3 are laminated in order from the lowest layer, and the upper surface edge 1b which forms the sidewalk 7 side of the side groove block 1 has the same edge. A notch 1a is formed over the entire length of the portion 1b, the edge of the entry block 2 overlaps the notch 1a and overlaps, and the inner wall surface of the notch 1a and the outer wall surface of the entry block 2 are brought into close contact with each other. An engagement notch 2a is formed in the lower edge 2b of the entry block 2 so as to correspond to the notch 1a, and the edge of the side groove block 1 is engaged with the notches 1a, 2a. Department and boarding block 2 And the edge portion is polymerized.

Also, as shown in the figure, in this embodiment, a low-height entry block 2 is used as a sidewalk boundary block, so that a person, a bicycle, a wheelchair, or the like can enter between the road 7 and the sidewalk 6. The structure allows easy operation. In FIG. 1, reference numeral 20 denotes another sidewalk boundary block having a predetermined height, which separates the boundary between the sidewalk 6 and the road 7 at a sufficient height.

The side groove block 1 according to the present embodiment has substantially the same structure as that described in the section of the prior art, and has an upper edge 1b on the side of the sidewalk 6 and a full length of the same edge 1b. The cross section forms a rectangular notch 1a.

That is, it is made of an elongated concrete having a hollow portion which becomes a water passage substantially at the center in a cross-sectional view, and the upper surface of the side groove block 1 is inclined so that the road 7 is slightly higher than the sidewalk 6. At the same time, the lower side surfaces are chamfered, and a cutout portion 1a having a rectangular cross section is formed in the upper surface edge 1b on the side of the sidewalk 6 over the entire length of the edge.

On the other hand, the entry block 2 according to the present embodiment is configured such that an elongated elongate concrete prism having a rectangular cross section is rounded by cutting off the corner of an upper corner forming the roadway 7 side when laying. A notch 2a for engagement corresponding to the notch 1a formed in the side groove block 1 is formed.

That is, a notch is formed in the lower surface edge 2b forming the side groove block 1 side at the time of laying, in the vertical direction and the horizontal direction over the entire length of the edge 2b, in a length corresponding to the notch 1a of the above-mentioned side groove block 1.
