DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a permeable construction member such as a permeable tile for use on road surfaces such as roads, sidewalks and parks, and on floors where rainwater falls such as verandas and rooftops.

[0002]

2. Description of the Related Art Conventionally, paving blocks are laid on road surfaces such as roads and sidewalks. Among these paving blocks, there is a so-called water-permeable block having water permeability. This is one in which a number of continuous fine gaps are provided inside the block and rainwater can penetrate downward. This water-permeable block generally has a cuboid shape.

[0003] When the water-permeable block is constructed, it is generally constructed on a sand cushion. That is, a layer of sand is provided on the layer of hardened crushed stone, and the permeable block is constructed thereon.

[0004]

However, in the above-described conventional permeable tiles, when the permeable tiles are disposed on the ground, rainwater that reaches the back surface from the front surface of the permeable tiles penetrates into the ground. If the penetration into the ground is low, rainwater will not be discharged after all.If a large amount of rainwater falls on the permeable tiles such as concentrated torrential rain, the rainwater will not be discharged. Quickly overflows above the surface of a permeable tile or the like.

Further, in places where rainwater falls such as a veranda in a house or where water is used, when water falls on the floor, even if a drain port is provided, a certain amount of water can be supplied to the floor. It accumulates on top and has to wait for the water to evaporate. At that time, even if the above-described water-permeable block is used, the water discharge capacity is not so high, so that the floor surface is kept wet.

Further, when the above-described permeable block is applied on a sand cushion, there is a problem that the permeated water causes a sand layer below the permeable block to flow out.

Accordingly, the present invention provides a construction member which can be installed on a floor or the like and which can improve the drainage capability of water such as rainwater, and a construction member in which a water-permeable construction member is constructed. It is intended to provide an effective construction method.

[0010] Secondly, in the first configuration, the groove portion has a plurality of grooves provided in different directions. Therefore, it is possible to efficiently discharge water in any direction of the water gradient.

Thirdly, in the first or second configuration, the groove portion includes a first groove group including a plurality of grooves provided in parallel to each other in a certain direction, A second groove group comprising a plurality of grooves provided in parallel with each other in different directions from each other, wherein the grooves in the first groove group and the grooves in the second groove group cross each other. I do. Therefore, in particular, since the grooves in the first groove group and the grooves in the second groove group intersect with each other, water can be discharged regardless of the inclination direction of the construction surface.

Fourth, in the third structure, the grooves in the first groove group and the grooves in the second groove group intersect at right angles to each other. I do. Therefore, since the grooves are arranged in a lattice, water can be efficiently discharged regardless of the inclination direction of the construction surface of the construction member.

Fifth, in the third or fourth configuration, the groove in the first groove group and the groove in the second groove group have a shape including a groove bottom and a pair of groove walls. And the groove wall is inclined toward the open side of each groove. Therefore, the frequency with which the permeated water reaches the groove can be increased, and the water discharge capacity can be increased.

A sixth aspect of the present invention is a method for constructing a construction member, wherein the construction member having any one of the first to fifth constitutions is constituted by at least one of concrete, asphalt, and a plate member. It is characterized by being arranged directly on the road or floor. A seventh aspect is a method of constructing a construction member, wherein the construction member having any one of the first to fifth configurations is used as a road surface or floor composed of at least one of concrete, asphalt, and a plate member. It is characterized by being arranged and fixed to the surface via an adhesive. This sixth
