Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] This invention relates to a heat insulating floor structure for an indoor ski resort.

[Prior Art] Fig. 4 is a cross-sectional view (a cross section perpendicular to an inclined surface) of an indoor ski resort made of steel. In the figure, the indoor ski resort l is the pillar 3 erected on the foundation 2.
It consists of a floor 4 formed above, walls 5 erected on both sides of the floor 4, and a roof 6 with a frame extending over the upper end of the wall 5. Indoor Niski maintains the indoor temperature at a low temperature of -3 to -5 degrees Celsius, and uses a snowmaking machine to deposit about 20 to 50 cm of snow on the floor to form a ski slope.

At the indoor ski resort, the temperature of the air space in the building is high (30 to 43 degrees Celsius in the summer), so the floor 4, walls 5, and roof are insulated to prevent heat from entering the indoors from the outdoors. It is necessary to have a structure. In particular, snow mats (to prevent snow from slipping) on the floors of indoor ski resorts
A drainage mat (similar to artificial turf with short fibers flocked to it) and a sheet waterproof layer that forms drainage gutters are attached, and snow is piled on top of this. When snow is used for downhill skiing, the surface of the snow gets dirty, so it is necessary to pile up new snow on top of the dirty snow and melt the snow at the bottom to regenerate the snow. Therefore, the top of the sheet waterproof layer that forms snow mats and drainage gutters is always covered with water, so if water leaks from the sheet waterproof layer or moisture barrier layer and enters the insulation material, the insulation ability of the insulation floor will decrease. Insulated floors must be moisture resistant. JP-A No. 60-17642 describes that aluminum foil or non-foamed film is pasted on the insulation material (polystyrene foam board) used for the walls of refrigerated warehouses to prevent water vapor from penetrating into the insulation material. However, an insulating floor structure suitable for indoor ski resorts under the above conditions has not yet been published.

[Problems to be Solved by the Invention] The following conditions must be satisfied for the insulated floor of an indoor ski resort.

(11) The insulating floor must be installed at an incline, and the inclination must not cause slipping (slippage) of the floor components.

(2) Even if water leaks from the sheet waterproof layer or moisture barrier layer pasted on the floor, it must be ensured that water does not infiltrate the insulation materials that make up the insulated floor.

(3) Insulated floors will be installed in a short period of time.

[Means for Solving the Problems] The present invention aims to solve the above problems,
Square timbers made of synthetic wood are installed on both sides of the inside of a rectangular parallelepiped frame made of steel plate with a rectangular bottom plate, and an insulation layer is provided in the center with the outer periphery of the insulation material wrapped in a sheet vapor barrier layer with aluminum foil. This is an insulating floor structure for an indoor artificial ski resort, characterized in that an insulating floor unit with a waterproof sheet layer attached to the upper surface of the material layer is installed in a rectangular concave section formed on a concrete base.

[Function] Square timbers and a heat insulating layer are housed inside a rectangular parallelepiped frame made of steel plate with a bottom plate, and a waterproof sheet layer is attached to the top surface of the square timbers, so water does not leak inside.

Furthermore, even if moisture enters the inside of the frame, it is wrapped in a sheet waterproof layer with aluminum foil, so moisture will not penetrate into the insulation material.

Furthermore, the heat insulating floor unit can be easily attached to the concrete base by simply mounting the heat insulating floor unit in a recessed portion of the concrete base.

[Example] An example of the present invention will be described below based on the drawings. The insulating floor of the present invention has a planar size of 3 to 10 m (vertical) x
They are built 3 to IOm (horizontal) and are installed side by side on the concrete foundation of the indoor Niski resort, forming the slope of the ski slope. FIG. 5 is a diagram showing a part of the plane of the insulating floor 10 installed on a concrete foundation, and a drainage gutter 20 for draining snowmelt water is provided between the insulating floor 10 installed side by side and the adjacent insulating floor 100. There is.

In FIGS. 1 to 3, the heat insulating floor unit 1° is constructed by installing square timbers 15 made of synthetic wood on both sides of a rectangular parallelepiped frame 11 made of steel plate having a rectangular bottom plate 12, and a heat insulating material in the center. A heat insulating layer 13 whose outer periphery is wrapped with a sheet moisture-proof layer 14 with aluminum foil is provided, and a sheet waterproof layer 16 is adhered to the upper surfaces of the square timbers 15 and the heat insulating layer 13. On the other hand, a large number of concave sections 25 formed in the grid-like partitions 23 are formed in the concrete M#22. The recessed section 25 is large enough to accommodate the heat insulating floor unit 10, and its depth is approximately 1/2 of the height of the heat insulating floor unit 10. The heat insulating floor unit IO is installed in the recessed section 25 of the concrete base 22, and a part of the space between the side walls of the adjacent heat insulating floor units 10 is filled with a heat insulating material 24. Next, the gutter material 17 (flanges are formed on both sides of the gutter body, and wood screw holes 18 are drilled at intervals in the flanges) is attached to the space above the heat insulating material 24, and placed on the square material 15. Attach the gutter material by screwing wood screws into the wood screw holes on the flange.

Thereafter, a sheet waterproof layer is attached to the bottom inner surface, inner wall, and flange surface of the gutter material 17. After that, the insulation floor unit 10
A snow mat 21 is attached to the upper surface and the upper part of the gutter 2o. Note that the shape of the bottom plate is not limited to a rectangular parallelepiped, but may be a hexagonal shape.

[Effects of the Invention] Since the insulating floor structure of the indoor ski resort of the present invention is configured as described above, the following effects can be obtained.

(1) Even when installed on an inclined surface, the insulation floor constituent members do not shift.

(2) Since the sheet waterproof layer is attached to the top surface of the heat insulating floor unit, snowmelt water does not flood into the rectangular parallelepiped frame. Furthermore, even if moisture enters the frame, the moisture-proof layer with aluminum foil that wraps around the outer periphery of the insulating material prevents moisture from entering, so the insulation ability of the insulating material layer does not deteriorate.

(3) Square timbers are placed inside the rectangular parallelepiped frame, reducing the need for expensive heat insulating material, so the heat insulating floor unit can be manufactured at low cost.

(4) Since the insulating floor unit can be manufactured in a factory, the insulating floor for indoor Niski lifts can be installed in a short period of time.
