Description

  The present invention relates to a walkway boundary block and a walkway boundary structure.

  Conventionally, the pedestrian block boundary block laid along the boundary between the roadway and the sidewalk completely divides the sidewalk and the roadway, and thus there is a problem that rainwater and snowmelt accumulate on the sidewalk (for example, patents) Reference 1). Therefore, the roadway from the sidewalk along the width direction to the pedestrian boundary block is used by using a concrete cutter or core cutter at the construction site at the construction site so that the water of the sidewalk flows into the gutter provided on the side of the sidewalk of the roadway. A water drain hole penetrating to the side is processed.

Since the drain hole is provided in advance, it is not necessary to process the drain hole at the construction site, and the construction time at the site can be shortened. Moreover, at the time of manufacture, the reinforcement | strengthening reinforcing bar is arranged avoiding a drain hole so that it may not be exposed, and the fall of the intensity | strength by providing a drain hole can be suppressed.

  The pedestrian road boundary block according to the present invention is preferably manufactured in advance in a factory. At this time, by reinforcing reinforcing bars around the drain holes, the strength can be increased and the quality can be improved. In addition, it is preferable that the water which flowed from the drain hole to the roadway flows into the side groove provided on the roadway.

  In the walkway boundary block according to the present invention, it is preferable that a bottom surface of the drain hole is inclined from the sidewalk side toward the roadway side. In this case, the water on the surface of the sidewalk can flow smoothly to the side of the roadway. Since the water does not stagnate in the drain hole, it is possible to prevent sand, dust, etc. from accumulating in the drain hole and the stagnant water from generating a bad odor.

  The pedestrian boundary structure according to the present invention includes a pedestrian road boundary block according to claim 1 or 2, wherein the pedestrian road boundary structure is laid along a roadway, a sidewalk provided along the roadway, and a boundary between the roadway and the sidewalk. And a side groove provided along the side of the side of the roadway.

  In the pedestrian boundary structure according to the present invention, since the pedestrian boundary block according to the present invention is laid along the boundary between the roadway and the sidewalk, water on the surface of the sidewalk can flow from the drainage hole to the side of the roadway. it can. For this reason, it is possible to prevent rainwater and snowmelt from accumulating on the sidewalk. Moreover, the water which flowed from the drainage hole to the roadway can be made to flow in the side groove provided along the sidewalk side part of the roadway.

Embodiments of the present invention will be described below with reference to the drawings.
1 to 4 show a pedestrian boundary structure and a pedestrian boundary block according to an embodiment of the present invention.
As shown in FIG. 1, the walking road boundary structure 1 includes a roadway 2, a sidewalk 3, a gutter 4, and a walking road boundary block 5.

The sidewalk 3 is provided along the roadway 2, and the surface is formed slightly higher than the surface of the roadway 2.
The side groove 4 is provided along the side of the side of the roadway 2.
The walkway boundary structure 1 is configured such that the surface of the roadway 2 is slightly inclined toward the side groove 4 so that water on the surface of the roadway 2 is collected and drained in the side groove 4.

  As shown in FIGS. 2 to 4, the walking path boundary block 5 is made of reinforced concrete and has a generally elongated rectangular parallelepiped shape. The pedestrian road boundary block 5 has an isosceles trapezoidal cross section along the end face, and the bottom surface 5b is wider than the top surface 5a. The pedestrian road boundary block 5 is chamfered so that both side edges of the upper surface 5a are rounded. The walkway boundary block 5 has a drain hole 11 provided at the center in the length direction so as to penetrate from one side surface 5c to the other side surface 5d along the width direction. The drain hole 11 has a rectangular shape, and is formed such that the height of the ceiling surface 11a gradually decreases from one side surface 5c toward the other side surface 5d.

  The pedestrian road boundary block 5 has a pair of misalignment preventing grooves 12 extending in the width direction at both ends of the bottom surface 5b. The groove 12 for preventing slippage can be prevented from being displaced along the length direction after construction by engaging with a convex portion provided on the installation surface. The walkway boundary block 5 is manufactured at a factory, and reinforcing bars are arranged around the drain hole 11 in order to increase the strength.

  As shown in FIG. 1, the walkway boundary block 5 is laid along the boundary between the roadway 2 and the sidewalk 3. In the walking road boundary block 5, one side surface 5c is arranged on the side of the sidewalk 3, and the other side surface 5d is arranged on the side of the roadway 2. The drain hole 11 has an inclined surface 11b formed of mortar at the bottom so as to be inclined from the sidewalk 3 side toward the roadway 2 side. The drain hole 11 is formed so that the inclined surface 11b has the same height as the surface of the sidewalk 3 on one side surface 5c and the same height as the surface of the side groove 4 on the other side surface 5d. Thereby, the drain hole 11 allows water on the surface of the sidewalk 3 to flow into the side groove 4 on the side of the roadway 2.

  In a specific example, the walking road boundary block 5 has a length of 2000 mm, a width of 150 mm at the top surface 5a, 190 mm at the bottom surface 5b, and a height of 200 mm. The drain hole 11 has a width of 200 mm, a height of 100 mm on one side surface 5c, and 80 mm on the other side surface 5d. The pedestrian boundary block 5 is constructed so that a plurality of pedestrian boundary blocks without the drain holes 11 are sandwiched therebetween so that the drain holes 11 are arranged at intervals of, for example, 10 m along the road 2. Note that the present invention is not limited to these numerical values.

Next, the operation will be described.
In the walking road boundary structure 1, since the walking road boundary block 5 is laid along the boundary between the road 2 and the sidewalk 3, the water on the surface of the sidewalk 3 flows from the drain hole 11 to the side groove 4 on the side of the road 2. be able to. For this reason, it is possible to prevent rainwater and snow melting water from accumulating on the sidewalk 3, and to prevent the feet of the pedestrian from getting wet or the water from freezing and the pedestrian from slipping. Further, the water that has flowed from the drain hole 11 to the roadway 2 can flow into the side groove 4 provided along the sidewalk side portion of the roadway 2. For this reason, it is possible to prevent water from accumulating on the roadway 2, and it is possible to prevent water splashing from the vehicle and freezing of the vehicle due to freezing of the vehicle.

  In the walking road boundary structure 1, the water on the surface of the sidewalk 3 can flow smoothly into the side groove 4 on the side of the road 2 by the inclined surface 11 b of the drain hole 11 of the walking road boundary block 5. Thereby, since water does not stagnate in the drain hole 11, it is possible to prevent sand or dust from accumulating in the drain hole 11 or stagnant water from generating a bad odor.

  In the walking road boundary structure 1, since the drainage hole 11 is provided in advance in the walking road boundary block 5, it is not necessary to process the drainage hole 11 at the construction site, and the construction time at the site can be shortened. Further, it is possible to avoid dangers associated with on-site processing, exhaust gas exhaust, dust and noise generation. Since reinforcing reinforcing bars are arranged around the drain hole 11 of the walkway boundary block 5, it is possible to suppress a decrease in strength due to the provision of the drain hole 11. Since the walkway boundary block 5 is manufactured in advance in a factory, it can maintain a certain quality.
