BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor structure of an indoor artificial ski resort which uses snow as a slope on a floor of a large space facility.

[0002]

2. Description of the Related Art In recent years, building construction methods using membrane roofs have
Buildings such as large space facilities with a pillarless structure can be obtained relatively easily. Such a large space facility is rich in its utility as various facilities, and for example, it can be used as an indoor artificial skiing area by snowing on the floor of the large space facility to make a slope.

[0003] When the large space facility is used as an indoor artificial ski resort as described above, the amount of snow on the slopes is always 30 or more.
It is necessary to keep the snow quality at a constant level of about cm. In other words, the lower snow layer of the slope is likely to be in an ice-burn state, melting the lower snow layer after the end of business hours,
It is necessary to level the surface of the slopes and make new artificial snow fall.

[0004] For this reason, the floor constituting the slope is devised in various ways in order to optimize the amount of melting of the lower layer of snow. For example, in JP-A-3-93905 (E01C 13/00), a concrete board, a waterproof coating, a heat insulating layer, a waterproof coating, a holding plate, and the like are laminated in order from the lower layer. It is controlled. In particular, by embedding a conduit for flowing a cooling medium or a heating medium in the heat insulating layer or in a concrete plate laid on the upper side of the heat insulating layer, and appropriately flowing a cooling medium or a heating medium through the conduit, It is possible to further improve the control amount of the snow melting amount, that is, the snow quality management.

[0005]

However, in such a conventional floor structure of an indoor artificial ski resort, the above-described laminate of the concrete substrate, the heat insulating layer, the holding plate, and the like is placed on the ground. It is to be installed. Therefore, there is a problem that when an external force such as an earthquake acts on the laminated body, the laminated body is displaced with respect to the ground and cracks are generated on the slope.

[0006] In view of the above-mentioned problems, the present invention can prevent cracks from being generated on the slope by securely fixing the laminate constituting the floor structure to the ground. An object of the present invention is to provide a floor structure of an artificial ski resort.

[0007]

Means for Solving the Problems In order to achieve the above object, a first configuration of the present invention is a floor structure of an indoor artificial ski resort that uses snow as a slope on a floor of a large space facility. A pile is driven into the ground on which the slope is formed, the tip of the pile is buried, a concrete base having a projection formed on the upper side is provided, and an underlayer of snow is provided above the concrete base.

[0008] In order to achieve the above object, a second configuration of the present invention is to form the above-mentioned slope in a floor structure of an indoor artificial ski resort which uses snow as a slope on a floor of a large space facility. The pile is driven into the ground to be buried, the tip of the pile is buried, and a concrete base with a projection is provided on the upper side. Above this concrete base, a heat insulating layer and a space through which a temperature-controlled heat transfer medium flows are provided. A base layer is formed by sequentially laminating a part, a layer such as sand, and a non-slip layer for snow.

Further, the space portion is constituted by juxtaposed concrete blocks formed of permeable concrete and having an inverted U-shaped cross section, and the projections of the permeable layer are formed on the upper surface of the concrete block. Is desirable.

[0010]

In the first configuration of the floor structure of the indoor artificial ski resort according to the present invention, the tip of the pile driven into the ground is buried in the concrete base. Through the ground. Therefore, in the sloped slope, relative movement between the ground and the concrete base is prevented, and it is possible to prevent displacement between the two. In addition, since the ground layer of the snow cover is locked to the projections formed on the concrete base, it is possible to prevent the occurrence of a gap between the ground layer and the concrete base, and Combined with prevention of displacement between the ground and the concrete base, it is possible to prevent cracks from being generated on the slope.

Further, in the second configuration of the present invention, similarly to the first configuration, the piles driven into the ground and the protrusions of the concrete base can prevent the displacement of each laminate. Needless to say, the base layer is formed by sequentially stacking a heat insulating layer, a space through which a temperature-controlled heat transfer medium flows, a permeable layer such as sand, and a snow non-slip layer.
The snow quality of the snow layer can be quickly and accurately managed by the temperature of the heat transfer medium flowing in the space. Further, the heat transfer medium in the space can be kept warm by the heat insulating layer.

Further, the concrete block having the inverted U-shaped cross section constituting the space is formed of permeable concrete, so that the temperature of the heat transfer medium flowing in the space is controlled via the permeable layer and the non-slip layer. This facilitates conduction to the snow layer, and the speed and accuracy of snow management of the snow layer can be further improved. Further, by forming the locking projections of the permeable layer on the upper surface of the concrete block, the permeable layer made of sand or the like can be prevented from shifting, and the underlayer can be stabilized.

A membrane roof 14 is stretched between the sections. The floor surface 18 of the large space portion 16 composed of the outer walls 12 and 12 and the membrane roof 14 is continuously inclined in the direction in which the outer walls 12 and 12 extend. The slope 20 is formed by piled up snow, and can be slid on the snow.

The membrane roof 14 is shown in a solid line state in FIG. 1 as being inflated by injecting air into the large space portion 16, and in a two-dot chain line state, the internal air pressure is eliminated. And deflated (contracted). A machine room 24 and a lift room 26 are provided outside the outer walls 12, 12.
An artificial snow machine, a snow gun, etc. will be installed.

The floor 18 has a floor structure shown in FIG. That is, the crushed stone 32 is laid on the ground 30 along the slope of the slope 20 to be constructed on the ground 30 with a predetermined thickness, and concrete is poured over the crushed stone 32 to form the concrete base 34. Form.
A reinforcing bar 36 is embedded in the concrete base 34.

When the concrete base 34 is cast, a plurality of piles 38 are provided on the ground 30 at appropriate intervals in the width direction (perpendicular to the plane of the drawing) and the length direction (horizontal in the drawing). Driving each of these stakes 38
Is buried in the concrete base 34. Then, in the portion where the pile 38 is buried,
A plurality of protrusions 34a projecting upward are formed on the upper side of the concrete base 34. The protrusion 34a
As shown in FIG. 3, it is preferable to alternately arrange the slopes 20 in the length direction in order to secure a discharge route for the snowmelt water.

On the upper side of the concrete base 34, a hard heat insulating layer 40 made of styrene foam or the like is laid with a predetermined thickness. The heat insulating layer 40 covers the outside of the protrusion 34a with a substantially uniform thickness.

A waterproof sheet 42 is laid over the entire surface of the heat insulating layer 40, and a reverse U-shaped section is formed on the upper side of the waterproof sheet 42 except for the covering portion of the projection 34a.
A number of character-shaped concrete blocks 44 are laid. Then, temperature-regulated air as a heat transfer medium whose temperature is controlled by an air conditioner (not shown) flows through a space 46 in the concrete block 44. This temperature-adjusted air is cooled and set to a temperature below the freezing point, for example, -5 ° C. when the artificial snow is caused to snow on the floor 18,
On the other hand, when melting the lower part of the snow cover, it is heated and set to, for example, + 2 ° C. Reference numeral 47 denotes a pipe for pressure-feeding the temperature-adjusted air to the center of the space 46.
The temperature adjustment air can be supplied substantially evenly over the entire space 46 via the.

The concrete block 44 is made of permeable concrete, and the concrete block 44 can transmit the snowmelt water and the temperature control air. Further, on one side of the upper surface of the concrete block 44 (the one side is a lower side with respect to the inclination direction of the slope 20), a locking projection 44a is integrally provided with a predetermined height. The height of the general portion of the concrete block 44 is set substantially equal to the height of the heat insulating layer 40 covering the projection 34a.

A permeable layer 48 made of sand or the like is laid on the upper side of the concrete block 44 with a thickness substantially equal to the height of the locking projection 44a. On the upper side of the transmission layer 48, an artificial turf 50 as an antiskid layer of snow is provided.
Is laid, and artificial snow 54 made by an artificial snowmaking machine is ejected from a snow gun and piled up on the artificial turf 50 to form a snow layer 52. Further, the heat insulating layer 40, the waterproof sheet 42, the space 46, the permeable layer 48, and the artificial turf 50 constitute an underlayer 54 for the snow layer 52.

With the above structure, in the floor structure of the indoor artificial ski resort 10 of this embodiment, a concrete block 44 having an inverted U-shaped cross section is laid over the heat insulating layer 40 via the waterproof sheet 42. Since a space 46 was formed in the concrete block 44 and the temperature-adjusted air was circulated in the space 46, the temperature of the temperature-adjusted air was
8 and the lower part of the snow layer 52 through the artificial turf 50. When the temperature-adjusted air is at the cooling temperature, the melting of snow can be prevented, and when it is at the heating temperature, melting of the lower part of the snow can be promoted.

Further, since the concrete block 44 is made of permeable concrete, a part of the temperature-adjusted air flowing through the space 46 passes through the concrete block 44 outward, and the passed temperature-adjusted air passes through the concrete block 44. Can be applied to the artificial turf 50 by raising the permeable layer 48. Therefore, the temperature of the temperature-regulated air is
And the snow quality of the snow layer 52 can be quickly managed, and the management accuracy can be significantly improved.

The snowmelt water, which melts the lower part of the snow layer 52 to be ice-burned, penetrates the artificial turf 50 and the permeable layer 48 and further passes through the concrete block 44 made of water permeable concrete. It falls into 46 and is discharged along the waterproof sheet 42 laid under the space portion 46. At this time, a drain hole 56 is formed at the lower end of the concrete block 44, and the snowmelt flows down the drain hole 56 sequentially.

By the way, in this embodiment, in forming the floor structure, when forming the concrete base 34 on the ground 30, the tip of the pile 38 driven into the ground 30 is buried in the concrete base 34. The concrete base 34 is connected to the ground 30 via the pile 38. Therefore, even when an external force such as an earthquake acts on the sloped slope 20, the relative movement between the ground 30 and the concrete base 34 can be prevented, and the displacement between the two can be prevented.

A projection 34a is formed on the upper side of the concrete base 34, and the heat insulating layer 40, the waterproof sheet 42, the space 46, the permeable layer 48 and the artificial Since the base layer 54 made of the grass 50 is provided, the base layer 54 is locked by the protrusions 34a, and it is possible to prevent the occurrence of a displacement between the base layer 54 and the concrete base 34. it can. Accordingly, the floor surface 18 can be prevented from being displaced with respect to the ground 30, so that cracks can be prevented from being generated on the slope 20.

Further, since the space 46 is disposed above the heat insulating layer 40, the temperature-adjusted air flowing through the space 46 can be kept warm. Therefore, the energy required to control the temperature of the temperature-adjusted air can be reduced as much as possible, and the air conditioner for producing the temperature-adjusted air can be reduced in size.

Further, the concrete block 44
A locking projection 44a is formed on the upper surface of the
The shift a prevents the transmission layer 48 made of sand or the like from shifting, thereby stabilizing the underlayer 54 itself.
