Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water permeable rubber pavement concrete board.

[0002]

2. Description of the Related Art Conventionally, a pavement concrete board has been developed in which a water-permeable rubber sheet obtained by sintering rubber particles is bonded to the upper surface of cement concrete or resin concrete board with an adhesive.

However, even if a drainage through hole is formed in the concrete plate, the water content immediately above the through hole, joint or notch is drained down through the through hole because of the adhesive layer at the upper and lower boundary portions. The water content immediately above the outer adhesive layer has a problem that it takes time for the water level to drop and it is difficult to drain the water.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to obtain a pavement concrete board in which rainwater contained in the water-permeable rubber board of a water-permeable rubber pavement concrete board is quickly drained from the concrete board. Another object is to obtain a paved surface that is easy to walk or run by using a relatively hard water-permeable rubber plate.

[0005]

In order to achieve the above object, the present invention is to connect a water-permeable rubber plate to the upper surface of the concrete pavement plate described in the claims, and to provide a drainage through hole in the concrete pavement plate. , A water-permeable rubber pavement concrete plate in which the connection is male and female engagement between the unevenness on the lower surface of the rubber plate and the unevenness on the upper surface of the concrete pavement plate. A guide groove facing the drainage through hole is provided on the upper surface of the concrete pavement plate. The water-permeable rubber pavement concrete plate according to item (1), wherein the female inclined surface of the male and female engaging portions faces the through hole, and is bonded with an adhesive to the male inclined surface in contact with the female inclined surface (1) or (2 ) The water-permeable rubber pavement concrete plate as described above, which is a joint for drainage instead of the through hole (1) (2) or
(3) The water-permeable rubber pavement concrete plate according to claim 3, which is a drainage notch instead of the through hole. (1) (2) or
(3) The water-permeable rubber pavement concrete plate as described above, wherein the water-permeable rubber plate is obtained by sintering a part of relatively hard rubber particles (1) (2) (3) (4) or (5) The water-permeable rubber-paved concrete plate according to claim (6), which is an adhesive instead of sinter.

[0006]

In the present invention, the rainwater that has entered the water-permeable rubber plate contains water on the concrete pavement plate. First, the water content immediately above the through hole for drainage, the joint for drainage or the notch for drainage is drained down.

After that, the water level of the water-permeable rubber plate is lowered by the drainage, and the water flows horizontally between the concave and convex engaging portions of the upper and lower boundaries along the boundary surface toward the through hole, joint or notch. The water is drained downward from the holes, joints or notches, the water level in the water permeable rubber plate is rapidly lowered, and the water content of the water permeable rubber plate is rapidly lowered.

[0008]

EXAMPLE A water-permeable rubber plate 2 having a high porosity formed by sintering or bonding 11 of relatively hard rubber particles 10 having a diameter of 2 to 4 mm (not a sponge), while cement concrete or The resin concrete pavement plate 1 is provided with a drainage through hole 3 as shown in FIGS. 10, 12, 15 and 16. Further, joints 8 or notches 9 between the pavement plates 1 and 1 are formed to support the rubber plate 2 on the upper surface.

For the connection, the male and female engagements 5 of the unevenness 4 and 4'formed on the lower surface of the rubber plate 2 and the unevenness 4 and 4'formed on the upper surface of the paving board 1 are shown in FIGS. Shown.
Further, as shown in FIGS. 8 and 9, the base portion of the rubber piece 12 having the engaging projection is inserted and bonded (FIG. 8) or the base portion is engaged (FIG. 9) in the concave portion 4 ″ formed in the rubber plate 2. Unevenness 4, 4 '
Can be formed. Further, as shown in FIG. 4, FIG. 15 (a) or FIG. 16 (a), a female inclined surface 7'inclined toward the central through hole 3 on the upper surface of the pavement plate 1 may be used as the male / female engaging portion 5. In that case, the lower surface of the rubber plate 2 becomes the male inclined surface 7 and the female inclined surface 7 ′ is formed on the upper surface of the pavement plate 1. In this case, both male and female surfaces 7, 7'are bonded with an adhesive 13 (this is shown in FIG. 4).

2, FIG. 3, FIG. 10, FIG. 12, FIG.
As shown in FIG. 18, the drainage through hole 3, joint 8 or notch 9
The guide groove 6 communicating with the above is provided on the upper surface of the pavement plate 1. As shown in FIG. 3 and FIGS. 14A and 14B, a square pipe 6 ′ is used to form a plurality of small water intake holes 6 ″ on the upper surface of the guide groove 6.

[0011]

EFFECTS OF THE INVENTION Since the present invention is configured as described above, the water-permeable rubber pavement concrete plate is quickly walked after rainwater contained in the water-permeable rubber plate 2 on the upper surface is quickly drained downward and the pavement surface is quickly dried. There is an effect that it is easy to do. Moreover, since the pavement surface is elastic but relatively hard, it has the effect of reducing foot fatigue during walking or running.
