[0055]

According to the first aspect of the present invention, there is provided an artificial grass laying outdoor and rooftop court, wherein after removing the artificial grass constituting the existing outdoor court, a flat substrate is provided on an upper surface portion of the water-permeable ascon. Synthetic resin in which upper and lower legs having predetermined heights are provided at predetermined intervals on the upper surface and the rear surface of the unit at predetermined intervals, and countless holes are formed in the substrate except for the legs. A new artificial turf was laid above the upper leg of the synthetic resin drainage buffer, so only the damaged artificial turf was removed and the amount of garbage in industrial waste disposal was reduced. The construction work period was remarkably shortened, and the construction cost was significantly reduced.

Further, the small hole of the present invention has an advantage that rainwater falls on the upper surface of the permeable ascon below and drains smoothly, and the rainwater does not accumulate in the ascon below the artificial turf.

Further, the drainage / buffer material of the present invention has an advantage that it can withstand various impacts sufficiently and has a restoring force so that it does not dent.

Further, since the drainage buffer material of the present invention smoothly discharges rainwater drained from the artificial turf onto the ascon, the rainwater is stored just below the artificial turf as in the related art, as the ascon is clogged. The situation where the artificial turf did not dry forever was solved at once.

According to a second aspect of the present invention, in place of the synthetic resin drainage / buffer, a leg portion having a recess on the back surface of a flat substrate portion and having a predetermined height is provided. Are provided at infinite intervals at predetermined intervals, and a synthetic resin drainage / buffer material having innumerable small holes at predetermined positions of the substrate portion is used, so that the same effect as described in claim 1 is obtained. .

Further, the present invention has an advantage that rainwater is slightly stored in the concave portion, gradually diffuses, moistens the turf portion of the artificial turf, and gives refreshment to competitors.

According to a third aspect of the present invention, in place of the synthetic resin drainage / buffer, a number of legs having a predetermined height are provided at predetermined intervals on the back surface of the flat substrate portion, and the substrate is provided with a plurality of legs. Since the drain / buffer material is formed by forming countless small holes at predetermined portions of the portion, rainwater flows out from the small holes onto the permeable ascon and is discharged therefrom.

Further, the substrate portion and the leg portion can sufficiently withstand various impact forces and have a restoring force, so that they do not dent.

According to a fourth aspect of the present invention, there is provided a drainage buffer made of a wire mesh having a predetermined height and a predetermined gap and having corrosion resistance, instead of the synthetic resin drainage buffer. It does not deform to various impacts and can withstand enough, and the rainwater can flow out very smoothly.

According to a fifth aspect of the present invention, in place of the synthetic resin plate material, a number of small holes with a small number of small holes are formed by projecting downwardly at predetermined intervals into a thin flat metal plate material or a synthetic resin plate material. Since the drainage buffer material has a part formed, rainwater flows out of the small hole and is discharged smoothly from the permeable ascon.

Further, since the legs protruding from the rear surface of the plate portion are sufficiently resistant to various impact forces and are not deformed, drainage of rainwater is smooth.

According to a sixth aspect of the present invention, in place of the synthetic resin drainage / buffer, a thin plate made of synthetic resin or rubber is provided on a back surface of a thin flat substrate made of metal or synthetic resin. Rainwater falls from the small holes because it is a drainage / buffer material in which a number of thin legs made of rubber or rubber are attached and countless holes are formed in the substrate.

Further, since the legs are not sufficiently deformed to withstand various impacts, there is an advantage that the legs are not dented and hinder the game.

According to a seventh aspect of the present invention, in place of the synthetic resin drainage / buffer, a thin flat substrate made of synthetic resin or rubber has a predetermined height on the back surface thereof and has a predetermined height. Since the legs are spaced from each other to form a myriad of small holes, and the drainage buffer material is used, rainwater flows out of the small holes and is discharged.

Further, the leg portion sufficiently withstands various impact forces, and the drainage / buffer material is not dented by the restoring force, so that the game can be smoothly performed.

In the invention according to claim 8, since the synthetic resin drainage / buffer material is formed by covering with a nonwoven fabric material filter, even if various impacts are applied to the drainage / buffer material, The filter alleviates the impact force and prevents deformation.

According to the ninth aspect of the present invention, the rainwater is smoothly spilled out and discharged from the gap because the synthetic resin drainage buffer is knitted and formed with an elongated rubber string instead of the synthetic resin drainage buffer.

Furthermore, since the present invention is knitted with a rubber cord, even if various impacts are applied to the artificial turf, the artificial turf cushions and has a quick restoring force, thereby reducing the degree of fatigue supported by competitors.

According to a tenth aspect of the present invention, a synthetic resin or rubber leg is provided on the back surface of the substrate on which the artificial grass is planted.
Since a number of legs are formed at a predetermined height and at predetermined intervals, rainwater flows out of the small holes onto the permeable ascon, and is drained, as in the first aspect.

Further, the substrate portion and the leg portions can sufficiently withstand various impact forces and have a sufficient restoring force, so that they are not dented.

The invention according to claim 11 is to provide asphalt waterproofing on the roof of a reinforced concrete building, form a lightweight concrete layer above the asphalt waterproofing layer, and provide the drainage buffer material above the concrete layer. Since the court was laid with artificial turf and rainwater, the rainwater could be smoothly drained and drained, and the construction period was shortened and the construction work was significantly reduced.
