BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing a construction of a pedestrian boundary block with a base or an apron according to the present invention.

FIGS. 1 to 4 show a first embodiment of a structure for constructing a footway boundary block with a base or an apron according to the present invention. The sidewalk road boundary block 1 with an apron is made of concrete, and as shown in FIG. 3, its sectional shape is, for example, substantially L-shaped.
It comprises a pedestrian road boundary block portion 1a extending upward, and an apron portion 1b extending laterally from below one side surface of the pedestrian road boundary block portion 1a. Grooves 1e, 1e that open upward, that is, open upward, are formed on both end surfaces 1c, 1c in the longitudinal direction of the block 1 at a required angle in the direction of the pedestrian road boundary block 1a. I have. The groove 1e extends continuously from the tip of the apron 1b to near the middle of the other side of the sidewalk boundary block 1a. When the blocks 1 and 1 are arranged such that their end faces 1c and 1c face each other, the grooves 1e form joints 2 with the grooves 1e and 1e facing each other. The joint 2 has a tapered portion 2b extending downward from the opening 2a opening upward at a constant width, and tapering downward so as to become wider from the opening 2a. The first and second end surfaces 1c and 1c are inclined surfaces that become deeper.

On the other hand, the joint member 3 inserted into the joint portion 2 is made of a rubber material such as ethylene propylene rubber as an elastic body. Its shape is substantially pentagonal in cross section as shown in FIG. Here, the side surface 3a of the joint member 3 has a tapered shape that becomes wider as it goes downward, and its upper surface 3b
A concave portion 3c having an arc-shaped cross section, for example, is formed so as to become deeper toward the center of the width, and is formed so as to be continuous in the longitudinal direction.

Next, the construction structure of the block 1 will be described in the order of construction. First, the base layer 4 is laid at the boundary between the sidewalk and the road on which the blocks 1 and 1 are arranged. The foundation layer 4 is formed by first laying crushed stones, forming a crushed crushed stone layer 4a, and further laying a dry mortar made of cement and sand to a thickness of, for example, about 20 mm. The mortar layer 4b is formed and completed.
Then, the blocks 1 and 1 are placed on the base layer 4 along the road so that the blocks 1 and 1 become the boundary between the sidewalk and the road, and the apron portions 1b and 1b are on the road side. Line up. Here, the grooves 1e, 1e of the adjacent blocks 1, 1 face each other, and the joints 2
To form Then, the joint member 3 is inserted into the joint portion 2 from above so as to be press-fitted. At this time, the joint member 3 inserted and arranged in the joint portion 2 has its elasticity.
The joint member 3 follows the shape of the joint, and the joint member 3
b is set to be lower than the upper surface 1d of the blocks 1 and 1.

Next, the operation and effect of the construction of the sidewalk boundary block with apron shown in the first embodiment will be described. When the vehicle passes over the apron portion 1b of the blocks 1 and 1, the blocks 1 and 1 are subjected to vibration due to the fluctuating load of the vehicle, but the blocks 1 and 1 are mutually connected via the joint member 3 made of an elastic body. Since the connection is made, the vibration is reduced, and no stress concentration occurs near the joint 2 of the blocks 1 and 1. Here, the blocks 1 and 1 are merely placed on the dry mortar layer 4b of the base layer 4, are not completely fixed, and the contact state between the base layer 4 and the blocks 1 and 1 is poor. Similarly, when the blocks 1 and 1 rattle with respect to the base layer 4, the rattling is similarly reduced, and no stress concentration occurs near the joint 2 of the blocks 1 and 1. Further, since the joint 2 is open upward, the upper surfaces 1d and 1d of the blocks 1 and 1 are separated from each other, and the joint 2 has an joint member 3 made of an elastic body. Therefore, even if the blocks 1 and 1 vibrate or rattle, the upper surface 1 of the blocks 1 and 1
d and 1d do not interfere with each other. Therefore, cracks and separation near the joints 2 of the blocks 1 and 1 can be prevented. The joint member 3 also plays a role of stopping water, and rain water or the like flowing down to the blocks 1 and 1 or flowing from the roadway side flows below the blocks 1 and 1 along the joint 2. Is preventing. The joint member 3 has an upper surface 3b whose upper surfaces 1d, 1d,
d, the joint member 3
Sand and soil easily accumulate on the upper surface 3b and the concave portion 3c of the
As a result, the joint member 3 is shielded from sunlight and its deterioration is suppressed, so that its life is extended. Also, the inserted joint member 3 has its side surface 3a abutting on the tapered portion 2b of the joint portion 2 and is prevented from coming off. As described above, the tapered portion 2b of the joint portion 2 is engaged with the joint member 3 and acts as a locking portion for preventing the joint member 3 from coming off, so that the joint member 3 easily comes out of the joint portion 2. Never. Further, since the joint 2 is processed simply by inserting the joint member 3, the work is easy, labor is saved as compared with the conventional mortar joint construction, and the curing time is not required. Can be greatly reduced. Further, when the joint member 3 is inserted into the joint portion 2, if a tool such as a flathead screwdriver is pressed against the concave portion 3 c of the joint member 3, the tip of the tool is guided to the center portion of the width of the joint member 3. . At this time, the concave portion 3c of the joint member 3 also
The joint member 3 is deformed so as to have a reduced width,
The side surface 3a also deforms so that the width is reduced, so that the joint member 3 can be easily inserted. Moreover, since the foundation layer 4 is composed of the crushed stone layer 4a and the dry mortar layer 4b thereon, the construction is easy.

FIGS. 5 and 6 show a second embodiment of the construction structure of a sidewalk boundary block with an apron according to the present invention, and are equivalent to FIGS. 2 and 4 of the first embodiment. In the second embodiment, the joint members and the construction method are only partially different from those of the first embodiment, and the other portions are the same. Therefore, only different portions will be described. The joint member 11 made of an elastic material such as a rubber material has substantially the same shape as the joint portion 2 of the block 1, and has an upper surface 11 a of the joint member 11.
Has no concave portion, and has a planar shape.
An adhesive material 1 is provided on one side surface 11 b of the joint member 11.
A double-sided adhesive tape 12 composed of 2a and release paper 12b is attached. In the construction of blocks 1 and 1,
In advance, the joint member 11 is inserted into the groove 1 e of the one block 1.
Is peeled off from the release paper 12b of the double-sided adhesive tape 12, and is attached. When the blocks 1 and 1 are arranged along the road, the joint member 11 is fitted into the groove 1e of the other block 1 and the joint member 11 is inserted into the grooves 1e and 1e facing each other, that is, the joint 2. Becomes Here, the upper surface 11a of the joint member 11 has substantially the same height as the upper surfaces 1d and 1d of the blocks 1 and 1.

Next, the operation and effect of the construction structure of the sidewalk boundary block with apron shown in the second embodiment will be described only on the points different from the operation and effect of the first embodiment. In the second embodiment, the joint member 11 has an upper surface 11a that is substantially the same height as the upper surfaces 1d and 1d of the blocks 1 and 1, so that sand, soil, and the like are placed on the joint member 11. It does not accumulate. In addition, since the joint member 11 is previously attached to the block 1, there is no need to press the joint member 11 with a tool after arranging the blocks 1 and 1.

The present invention is not limited to the above-described embodiment, and various other modifications are possible. For example, the joint members 3 and 11 may be elastic members, and may not be made of a rubber material but may be made of a soft synthetic resin material. Further, the shape of the joint member 3 is not limited to a shape having a substantially pentagonal cross section, and the shape of the concave portion 3c formed on the upper surface 3b of the joint member 3 is not limited to an arc-shaped cross-section, but may be a center of the width. What is necessary is just to be formed so that it may become deeper toward a part, for example, it may be tapered.

Further, the present invention relates to a base-assisted walkway comprising a base portion 13a and a pedestrian-way boundary block portion 13b projecting upward at substantially the center of the base portion 13a as shown in FIG. The present invention can also be applied to the roadway boundary block 13, and the joint 2 between the blocks 13, 13 installed on the base layer 4 is lower than the upper surface of the block 13, as in the first and second embodiments. Thus, the joint member 3 made of an elastic body is inserted. Thus, even if the vehicle passes over the base portion 13a of the block 13 and the block 13 vibrates due to a fluctuating load received from the vehicle, the blocks 13 are connected to each other via the joint member 3 made of an elastic body. Therefore, the vibration is alleviated, and stress concentration does not occur near the joint 2 of the block 13. However, the shape of the baseway or apron-equipped sidewalk boundary block according to the present invention has the above-described sectional shape. The shape is not limited to a convex shape having a substantially L-shaped shape or a substantially inverted T-shaped cross section, and may be a shape having another shape.
