BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an artificial ski resort floor slab that allows the uneven surface and slope angle of an artificial ski slope to be quickly changed.

0002

2. Description of the Related Art Ski resorts are built using slopes in mountainous areas, and the way you enjoy them changes depending on the angle of slope and the distance of the slope. However, there was a limit to the number of locations suitable for the facility. Therefore, in some cases, artificial ski slopes were built on the ground, and in other cases, artificial slopes were built in urban areas of cities, and artificial snow was laid down. When constructing artificial slopes in urban areas, the fixed slopes were constructed in a spiral shape in order to make effective use of the land area.

0003

[Problems to be Solved by the Invention] Fixed slopes have the disadvantage that skiers get tired of them. On a natural ski slope in a natural environment, the unevenness of the snow changes depending on snowfall conditions and wind direction, and it is possible to enjoy the changes in the slope surface to a certain extent. Therefore, attempts have been made to artificially create variations in unevenness on artificial ski slopes.

The present invention has been made in view of the above circumstances, and its purpose is to provide an artificial ski resort floor slab that can easily and quickly change the slope angle of the ski slope and the change cycle of the slope angle. .

[0005]

[Means for Solving the Problems] In order to achieve the above object, the artificial ski resort floor slab of the present invention catches snow with artificial turf, under which insulation material, cooling pipes, and waterproof mats are laminated. Constructed to be supported by expanded metal,
Furthermore, the girder support beam supporting the expanded metal was supported by a plurality of jacks placed at intervals in the axial direction of the beam.

[0006]

[Operation] Change the amount of each jack up and change the angle of inclination of the girder support beam. Waterproof mats, cooling pipes, insulation materials, etc. are protected by expanded metal against changes in the angle of the girder supports. The artificial turf keeps the snow in place and prevents it from slipping.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will now be described in detail with reference to the drawings. Each figure shows an embodiment of the present invention, and FIG. 1 shows a panoramic view of an artificial ski resort 1. The slope deck 3 which spreads out in a fan shape is supported by pillars 5 at three balanced points in a multi-story structure, each inclined. The outer periphery of the ski slope floor slab 3 is surrounded by a wall 7, and the floor slab 3 is protected from the external environment.
It protects the artificial snow above.

The ski slope floor slab 3 is the same thing even if it is called an artificial ski resort floor slab, and the floor slab 3 of the present invention is shown in cross section in FIG. This slope floor slab 3 has a cooling pipe 11 laid on the back side of the artificial turf 9, and a rubber waterproof mat 12 laid underneath. The artificial grass 9 is for preventing the artificial snow 13 from falling from the surface of the floor slab 3, and is preferably water permeable so that the artificial snow 13 is difficult to melt. Further, the cooling pipe 11 cools the back surface of the artificial grass 9 to such an extent that the artificial snow 13 does not melt. Water droplets from the artificial turf 9 and the cooling pipe 11 are caught by a waterproof mat 12. Furthermore, a heat insulating material 15 is placed under the waterproof mat 12,
Beneath it, a galvanized expanded metal 17 with a steel frame is spread out. A drainage gutter 19 is arranged intermittently under the back surface of the expanded metal 17, and a drain pipe 21 is hung vertically from the surface of the waterproof mat 12 above the drainage gutter 19. The expanded metal 17 is for supporting the insulation material 15, the waterproof mat 12, the cooling pipe 11, the artificial grass 9, and the artificial snow 13 with flexibility, and further supports the expanded metal 17 with a girder 23, The girder 23 is supported by girder support beams 25. That is, the slope deck 3 is a laminate supported by girder support beams 25. If the girder support beam 25 tilts, the ski slope floor slab 3 itself tilts. Therefore, the girder support beams 25 may not be straight, but may be curved vertically in advance, or a plurality of girder support beams 25 may be aligned in the axial direction, and a different inclination angle may be set for each fixed length. You can have it. This creates undulations.

Since the main purpose of the present invention is to change and form the above-mentioned undulations simply and quickly, FIG.
7 is shown schematically. A part of the structure is also shown in FIG. 2, in which separate jack rods 29 are pivoted at intervals in the axial direction of the girder support beam 25. If the different jack rods 29-29a are jacked up at the same distance, the girder support beam 25 will be horizontal, but if there is a difference, it will be tilted. In the figure, the girder support beams 25 are received by inclined pedestals 31 in order to give the slope deck 3 a certain inclination from the beginning without increasing the amount of jacking up on one side. The slanted pedestal 31 is a pedestal whose bottom side is horizontal and whose upper side has an inclination angle along the axial direction of the girder support beam 25. The girder support beam 25 is axially connected to brackets 32 - 32 a erected at both ends of the upper side of the slanted pedestal 31 . That is, the brackets 32-32a are U-shaped and sandwich the girder support beam 25, and the fixing bolts 33 are passed through the girder support beam 25 from the side surfaces of each of the brackets 31-31a. Furthermore, the bottom of the slanted pedestal 31 is almost the bracket 32-32a.
It is supported by jack rods 29-29a of separate hydraulic jacks 37-37a fixed to the girder 35 directly below. Flexible stands 39-39 with semicircular notches facing down are provided at both ends of the bottom of the slanted pedestal 31, and a rib-shaped reinforcing plate 41 is provided between the slanted pedestals 39 and at the bottom of the slanted pedestal 31. The tips of the jack rods 29-29a are in contact with the semicircular notch circumferential surface of the flexible base 39, and the support load is distributed to the bottom surface of the inclined base 31. In addition, in consideration of safety, a cylindrical side pressure receiver 45 is erected and fixed in the center of a base 43 that is integrally fixed with the jack 37-37a on the girder 35, and the bottom of the inclined base 31 is fixed therein. A guide plate 47 extending vertically downward from the center is housed in a vertically slidable manner. The guide plate 47 has a size that fits loosely into the inner diameter of the side pressure receiver 45, and a center plate 49 reinforced by applying reinforcing plates 41 at the bottom of the slanted pedestal 31 on both sides extends vertically downward. There are two sheets spaced apart above and below.

When the jacks 37-37a are driven, the jack rods 29-29a extend and contract up and down. At this time, the guide plate 47 at the bottom of the center plate 49 is restrained from side to side by the side pressure receivers 45, and the slanted pedestal 31 is held by the jack rods 29-29.
It moves up and down without applying any lateral stress to a. If the jack rod 29 of the jack 37 is lowered and the jack rod 29a of the jack 37a is extended, the slanted pedestal 31 and the girder support beam 25 will be removed from the stop bolt 33 and the flexible pedestal 3.
Together with the action of 9, the slope slopes smoothly upward to the right. Of course,
If the expansion and contraction of the jacks 37-37a is reversed, the inclination will be the opposite.

[0011]

[Effects of the Invention] As described above in detail, according to the artificial ski resort floor slab of the present invention, snow is caught by the artificial turf, so snow does not slide off the floor slab. In addition, a cooling pipe is provided on the back side of the artificial turf to prevent snow from melting, and a waterproof mat provides a laminated structure that is sufficient to prevent water leakage.These are supported by expanded metal, so the expanded metal structure is as described above. can be freely changed up and down.

Furthermore, since the girder support beams are supported by jacks at intervals in the axial direction, by controlling the vertical movement of each jack, the inclination angle of the girder support beams can be changed, and the undulations of the ski resort floor slab can be adjusted. It has the effect of quickly changing the situation.
