[0009] Hereinafter, an edge block according to one embodiment of the present invention will be described in detail with reference to Figs. As shown in Fig. 1, a curb block 1 according to one embodiment of the present invention drains rainwater, snowwater, and the like flowing on the side edge of a road 3, i.e., on a road shoulder or roadside strip, into a U-shaped gutter or a catchment basin, and is installed on the U-shaped gutter or the catchment basin (in the figure, the curb block 1 is placed on a U-shaped gutter 5). The curb block 1 is placed between L-shaped blocks 7, 7 at a predetermined interval in the traveling direction of the road 3, and includes a base portion 11, a curb 13, a base portion side cover body 15, and a curb side cover body 17. As shown in Fig. 5, the base portion 11 and the curb 13 are integrally formed as a block body 19, which is L-shaped in side view and made of concrete.

[0010] As shown in Figs. 2 to 5, the base plate portion 11 has a generally rectangular shape in plan view, and its upper surface is gently inclined diagonally downward in the road width direction of the road 3, i.e., in the direction from the road 3 side to the curb 13 side (see Fig. 3), and a drainage opening 21 that is rectangular in plan view is formed in the center. Furthermore, the base plate portion 11 has a base plate side step portion 23 formed on the opening edge of the drainage opening 21 to fit a frame material 61 (see below) of the base plate side cover body 15. The depth of the base plate side step portion 23 is generally equal to the height of the base plate side cover body 15. Furthermore, a drainage channel 25 that communicates with a U-shaped gutter 5 or a catchment basin is provided on the upper surface of the base plate portion 11 on the road 3 side. As shown in Figure 3, the drainage channel 25 is intended to guide rainwater, etc. from the road 3 side or rainwater when the base side cover 15 is blocked by garbage, fallen leaves, etc., to the U-shaped gutter 5 or catch basin, and is equipped with, from the road 3 side, a first incline 27 with a steep slope extending diagonally downward from the road 3 toward the curb 13, a second incline 29 with a gentle slope connected to the first incline 27 and extending diagonally downward from the road 3 toward the curb 13, a third incline 31 with a steep slope connecting to the second incline 29 and extending diagonally downward from the road 3 toward the curb 13, and a flow path 33 extending vertically of the edge block 1 connecting to the third incline 31, the drainage opening 21, and the U-shaped gutter 5 or catch basin.

[0011] As shown in Figs. 2 and 5, the curbstone 13 is a rectangular parallelepiped that is long along the traveling direction of the road 3, and is formed integrally with the upper surface of the base plate 11 on the side opposite the road 3. The curbstone 13 includes a drainage section 35 having a first drainage outlet 37 formed on its front surface (the surface facing the road 3) and a second drainage outlet 39 formed on the front side of the upper surface (the upper surface facing the base plate 11), a left wall section 41, a right wall section 43, a rear wall section 45, and a bottom section 47. The first drainage outlet 37 and the second drainage outlet 39 of the drainage section 35 are for directing rainwater, snowwater, etc. to the U-shaped gutter 5 or a catchment basin, and each opening width (width on the traveling direction side of the road 3) is formed wider than the opening width of the drainage opening 21 of the base plate 11. The left wall 41 and the right wall 43 have steps 49L and 49R formed on the inner edges thereof for fitting the curb side cover 17, and the rear wall 45 has a front edge formed with a step 51 for fitting the curb side cover 17. The rear wall 45 has a front surface formed with a plurality of through holes 55, 55 for inserting fasteners 53 for fixing the curb side cover 17 to the curb 13. The bottom 47 is located on the left and right sides of the lower front surface of the rear wall 45, and is formed to extend from the inner wall surfaces of the left wall 41 and the right wall 43. Between the bottoms 47 and 47, a drainage flow passage 57 is formed that extends vertically of the edge block 1 and communicates with the first drainage outlet 37 and the second drainage outlet 39.

[0012] As shown in Fig. 1, Fig. 6(a) and Fig. 6(b), the base plate side cover 15 has a generally rectangular shape in plan view and includes a cover body 59, a frame material 61 and a road side cover piece 63. The cover body 59 includes an outer frame 65 that fits into the frame material 61, a plurality of horizontal bar pieces 67 that extend in the traveling direction of the road 3 and are provided at predetermined intervals, and a plurality of diagonal bar pieces 69 that are provided in an accordion-like shape between the long piece (the piece in the traveling direction of the road 3) of the outer frame 65 and the horizontal bar piece 67 and between the horizontal bar pieces 67 and the horizontal bar pieces 67. The spaces formed between the outer frame 65, the horizontal bar pieces 67 and the diagonal bar pieces 69 are water holes 71 that guide rainwater, snowwater and the like to the drainage opening 21. As shown in Figures 3 and 6(b), the road side cover piece 63 is a plate material that is L-shaped when viewed from the side, and is intended to cover part of the drainage channel 25 to prevent tires of motorcycles, etc. from getting stuck in the drainage channel 25 of the base material portion 11, and is fixed by welding to the outer circumferential surface of the frame material 61 on the road 3 side.

[0013] As shown in FIG. 1 and FIG. 6(c), the curb side cover body 17 is fixed to the curb 13 by fitting into the step portions 49L, 49R of the left wall portion 41 and the right wall portion 43 of the curb 13 and the step portion 51 of the rear wall portion 45. The curb side cover body 17 has a vertical cover 73 that covers the first drainage opening 37 of the curb 13, an upper cover 75 that is integrally formed on the upper portion of the vertical cover 73 and covers the second drainage opening 39 of the curb 13, and fixing plates 77, 77. The connection portion between the vertical cover 73 and the upper cover 75 is a curved portion 79. The vertical cover 73 has rectangular water passage holes 81, 81 that are provided at a predetermined interval along the traveling direction of the road 3 and are arranged in two rows, one above the other. The curved portion 79 has a plurality of rectangular water passage holes 83 provided at a predetermined interval along the traveling direction of the road 3. The water-through holes 83 formed in the curved portion 79 are provided with slanted pieces 85 that connect opposing corners (diagonals). The slanted pieces 85 of the water-through holes 83 are provided so as to connect diagonals that alternate between different angles. As shown in Figures 3 and 6(c), the fixing plates 77, 77 are L-shaped in side view, and have insertion holes 87 for inserting the fasteners 53 therethrough.

[0014] Next, drainage of rainwater, snowwater, etc. by the edge block 1 according to this embodiment will be described with reference to FIG. When the water passage hole 71 of the base plate side cover 15 and the water passage holes 81, 83 of the curb side cover 17 are not blocked by garbage, fallen leaves, etc., rainwater, snow water, etc. flowing from the L-shaped blocks 7, 7 pass through the water passage hole 71 of the base plate side cover 15 and the water passage holes 81, 83 of the curb side cover 17, flow to the drainage opening 21 of the base plate side cover 15 and the drainage flow path 57 of the curb 13, and are drained into the U-shaped gutter 5 or the catchment basin. In addition, rainwater, snow water, etc. flowing directly from the road 3 side to the curb block 1 is drained into the U-shaped gutter 5 or the catchment basin through the drainage channel 25 of the base plate part 11. At this time, fallen leaves that flow in with the rainwater and snow water can be discharged through the drainage channel 25 into the U-shaped gutter 5 or the catchment basin.

[0015] On the other hand, when the water passage hole 71 of the base plate side cover 15 and the water passage holes 81, 83 of the curb side cover 17 are blocked by garbage, fallen leaves, etc., rainwater, snow water, etc. are difficult to flow through the water passage hole 71 of the base plate side cover 15 and the water passage holes 81, 83 of the curb side cover 17 to the drainage opening 21 of the base plate side cover 15 and the drainage flow path 57 of the curb 13, but the rainwater, snow water, etc. that is not drained from each water passage hole 71, 81, 83 flows around the garbage, fallen leaves, etc. accumulated on the upper surface of the base plate side cover 15 and the lower part of the curb side cover 17 and flows into the drainage channel 25 of the base plate part 11. As a result, the rainwater, snow water, etc. are drained through the drainage channel 25 to the U-shaped gutter 5 or the catch basin. This makes it possible to prevent rainwater, snow water, etc. from accumulating on the shoulder or side strip of the road 3.

[0016] As described above, according to the edge block 1 of one embodiment having the above-mentioned configuration, the following effects can be obtained. By providing a drainage channel 25 that communicates with a U-shaped gutter or catchment basin on the upper surface of the base plate 11 of the curb block 1 facing the road 3, even if the water passage hole 71 of the base plate side cover 15 and the water passage holes 81, 83 of the curb side cover 17 are blocked by garbage, fallen leaves, etc., rainwater, snow water, etc. will flow around the garbage and fallen leaves accumulated in the base plate side cover 15 and into the drainage channel 25. This allows rainwater, snow water, etc. to be guided to the U-shaped gutter 5 or catchment basin, preventing a decrease in the drainage function of the curb block 1.

[0017] By providing the base plate side cover body 15 with a road side cover piece 63 that covers part of the drainage channel 25, even if a motorcycle or the like passes over the edge block 1, the tires of the motorcycle or the like can be prevented from getting stuck in the drainage channel 25.

[0018] In one embodiment of the edge block 1, the road side cover piece 63 of the base plate side cover body 15 that covers part of the drainage channel 25 of the base plate portion 11 is a rectangular plate material (see FIG. 2), but as shown in FIG. 7, the tip of the road side cover piece 63 on the road 3 side may be sawtooth-shaped. In this case, the tip is rounded so as not to damage tires of motorcycles, etc. With this configuration, fallen leaves can also be easily discharged into the U-shaped gutter 5 or catchment basin.

[0019] In one embodiment of the edge block 1, as shown in Fig. 8, the drainage channel 25 may be provided with a plurality of grooves 88 extending from the road 3 side toward the curb side. With this configuration, even if fallen leaves are on the drainage channel 25, rainwater, snow water, etc. can be drained through the plurality of grooves 88 into the U-shaped gutter 5 or catch basin, improving the drainage function.

[0020] In one embodiment of the edge block 1, the base plate portion 11 and the curbstone 13 are integrally formed as a block body 19, but the base plate portion 11 and the curbstone 13 may also be separate bodies and then combined with the base plate portion 11 and the curbstone 13 to form a block body.

[0021] In the curb block 1 according to one embodiment, the curb side cover body 17 is fixed to the curb 13 by a fastener 53, but the curb side cover body 17 may also be embedded in the curb 13 and fixed thereto. [Explanation of symbols]
