Abstract

PURPOSE:To prevent the occurrence of a snowslide by bringing in the same plane the respective upper surfaces of both a rectangular outer frame and an intermediate frame at the lower part of which a plurality of draining holes have been provided, and by positioning the undersurface of the intermediate frame higher than that of the outer frame to form a base, and then by planting artificial lawn grass on the upper surface thereof. CONSTITUTION:A base 2 comprises a rectangular outer frame 3, and an intermediate frame 5 which is fixed in the outer frame 3 in a lattice shape and at the lower part of which a plurality of semicircular draining holes 4 are formed; and a plurality of bases 2 are laid on the surface of an inclined floor 1. And the upper surface of the outer frame 3 is brought into line with that of the intermediate frame 5, and the undersurface of the intermediate frame 5 is positioned higher than that of the outer frame 3, and on the upper surface thereof, artificial lawn grass 6 is planted. Further, the bases 2 are fixed on the inclined floor 1 by means of an adhesive or the like, and mat is fixed on the inclined floor 1. Thus, the snow layer 7 piled up on the inclined floor 1 intrudes into the bases 2 and also bites into the artificial lawn grass 6, and snow water passed through the draining holes 4 is drained downward along the inclined floor 1.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides floor mats for artificial ski resorts, particularly for reliably preventing slipping of a layer of snow laid on the floor of an indoor Niski resort. The present invention relates to floor mats for artificial ski resorts that can be used as floor mats.

[Conventional technology]

Conventional indoor Niski resorts were only open during the winter when the outside temperature was low, but in recent years, the development of indoor Niski resorts that can be open throughout the year has been progressing, and some have actually been constructed.

One of the problems faced by indoor snow ski resorts that are open all year round is the phenomenon in which snow accumulated on the floor slides down when the indoor temperature rises as the outside temperature rises. , there is a problem of avalanche occurrence.

The occurrence of this avalanche not only prevents the temperature from rising inside the artificial ski resort, but also increases the frictional force between the floor of the artificial ski resort and the snow accumulated on this floor, and makes it possible to efficiently drain snowmelt water. This can be effectively prevented by doing so.

Mats are pasted on the floor as a means to increase the friction between the floor and snow and to efficiently drain snowmelt water.
It is conceivable to deposit snow on this mat. The second mat is a conventionally known mat consisting of resin artificial turf planted vertically on a resin substrate.

The snow that accumulates on the mats bites into the artificial turf planted on the mats, thereby preventing avalanches from occurring.

[Problem to be solved by the invention]

However, the above-mentioned conventionally known mats have the following problems. That is, ■ Since the artificial turf is planted perpendicular to the substrate,
As the inclination angle of the mat increases, the frictional force between the snow accumulated on the mat and the grass on the mat decreases, resulting in a decrease in the anti-slip effect of the snow.

■ Mat substrates lack water permeability, so snowmelt water cannot be drained away efficiently.

Therefore, an object of the present invention is to provide a floor mat for an artificial ski resort that can effectively prevent the occurrence of avalanches.

[Means to solve the problem]

This invention consists of a base that is laid on a sloped floor surface of an artificial ski resort, and the base has a rectangular outer frame and a plurality of water bodies fixed at the bottom in a grid pattern within the outer frame. an inner frame with a punched hole formed therein, the upper surface of the outer frame and the upper surface of the inner frame coincide with each other, the lower surface of the inner frame is located above the lower surface of the outer frame, and the outer frame It is characterized in that artificial grass is planted on the upper surface and the upper surface of the middle frame.Next, an embodiment of the floor mat for an artificial ski resort according to the present invention will be described with reference to the drawings. I will explain while referring to it.

FIG. 1 is a sectional view showing an embodiment of the floor mat for an artificial ski resort according to the present invention, and FIG. 2 is a perspective view showing the same embodiment.

As shown in FIGS. 1 and 2, the floor mat for an artificial ski resort according to the present invention consists of a plurality of bases 2 laid side by side on a sloped floor made of concrete.

The base 2 consists of a rectangular outer frame 3 and an inner frame 5 fixed in a grid pattern within the outer frame 3 and having a plurality of semicircular drainage holes 4 formed at the bottom thereof. The upper surface of 3 and the upper surface of the middle frame 5 match, the lower surface of the middle frame 5 is located above the lower surface of the outer frame 3, and the upper surface of the outer frame 3 and the upper surface of the middle frame 5 are covered with artificial grass. 6 has been planted.

The reason why the lower surface of the inner frame 5 is located above the lower surface of the outer frame 3 is to drain water when melting snow.

The outer frame 3 has, for example, dimensions of 300 cm in width, 400 cm in length, and 20 m in height, and is made of a board made of FRP or the like and has a thickness of 10 m. The diameter of the drain hole 4 is about 10 wφ, and the grid interval of the middle frame 5 is about 50 m. The length of artificial grass 6 is
It is about lO■.

According to the floor mat for an artificial ski resort of this invention, the snow layer 7 accumulated on the sloped floor l can be prevented from slipping in the following manner.

That is, the base 2 is fixed on the inclined floor l with an adhesive or the like, and the mat is fixed on the inclined floor l. The snow layer 7 accumulated on the sloped floor 1 enters into the base 2 and bites into the artificial grass 6, so that slipping of the snow layer 7 is reliably prevented. Moreover,
Water from melting snow is well drained down the sloped floor 1 through the drainage holes 4, so that the snow layer 7 is reliably prevented from slipping in this respect as well.

〔Effect of the invention〕

As explained above, according to the present invention, the snow layer on the sloped floor penetrates into the base and bites into the artificial turf, and moreover, the snow melting water is efficiently drained outside, so the snow layer on the sloped floor This brings about the useful effect of reliably preventing the layer from slipping.
