Abstract

PURPOSE:To prevent deviation of heat insulated floor components by providing inside a rectangular steel-plate made frame a heat insulated floor unit having an aluminum-foil coated sheet-moistureproofing layer at its outer periphery, and nutfastening an anchor bolt of a concrete base to a flange of the frame. CONSTITUTION:An aluminum-foil coated sheet moistureproofing layer 17 is formed on the outer periphery of a heat insulator layer 16 and this layer 16 is provided inside a steel-plate made frame 11 having a flange 14 extending outwardly from the bottom of its outer periphery, to form an adiabatic floor unit 10. This unit 10 is placed on a concrete base 20 and a pressing plate 15 is put on the adjacent flanges 14. Then, an anchor bolt 21 of the concrete base 20 is fastened by a nut for fixation of the units 10. Thereafter, a heat insulator 22 is charged between side walls 13 of the adjacent steel-plate made frame 11 to form a drainage waterpipe 19 over the heat insulator 22. This prevents deviations of the floor component members and intrusion of water into the frame 11.

Description

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

[Prior Art] Fig. 3 is a cross-sectional view (a cross-section perpendicular to a slope) of an indoor ski resort made of steel. In the figure, an indoor varnishing station 1 is a column 3 erected on a 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 indoor temperatures at a low temperature of -3 to -5 degrees Celsius, and uses a snowmaking machine to deposit about 20 to 50 acre of snow on the floor to form a ski slope. At indoor ski resorts, the temperature of the air space in the building is high (30 to 43°C in the summer), so the floor 4, walls 5, and roof are It is necessary to have an insulated structure. In particular, snow mats (artificial turf-like drainage mats with short fibers flocked to them) are used to prevent snow from slipping on the floors of indoor ski resorts.
A sheet waterproof layer is pasted on to form a drainage gutter, and snow is piled up 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 provided with a moisture barrier. JP-A No. 60-17642 describes that aluminum i 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.

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

(22) Even if water leaks from the sheet waterproof layer or vapor barrier layer pasted on the floor, it must be ensured that water does not enter the insulation material that makes up the insulated floor.

(3) The insulation floor can be installed in a short period of time.

[Means for Solving the Problems] The present invention attempts to solve the above-mentioned problems, and includes forming a side wall extending downward from the outer edge of a rectangular top plate,
A heat insulating floor unit, which has a sheet moisture barrier layer with aluminum foil on the outer periphery of the heat insulating material, is installed inside a steel plate frame with a flange extending horizontally on the outer periphery of the lower end of the side wall, and is tightened to anchor bolts on the concrete foundation. This is an insulated floor structure for indoor artificial ski resorts featuring:

[Since the heat insulating material layer is provided within the working frame, even if the heat insulating floor unit is installed on an inclined surface, only a gap will occur between these layers.

Furthermore, since a top plate is provided, it is possible to prevent water from entering the frame, and even if moisture enters the frame, the moisture-proof layer with aluminum foil prevents moisture from entering the heat insulating material.

Further, by tightening the heat insulating floor unit to the anchor bolts of the concrete foundation, the heat insulating floor unit is firmly fixed.

[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-lom (horizontally) and are installed side by side on the concrete foundation of the indoor Niski resort to form the slope of the ski slope. Fig. 4 is a diagram showing a part of the plane of the insulating floor lO installed on the concrete foundation, and a drainage @ 19 for draining snowmelt water is provided between the insulating floors 10 installed side by side and the adjacent insulating floors 10. ing.

In FIGS. 1 and 2, the insulating floor unit IO is
A side wall 13 is formed extending downward from the outer edge of the rectangular top plate 12, and a flange portion 1 extends horizontally to the outer circumference of the lower end of the side wall 13.
4 is formed by providing a sheet moisture-proof layer 17 with aluminum foil around the outer periphery of the heat insulating material.

The flange portion 14 of the steel plate frame 11 is provided with notches 23 at intervals for inserting bolts. - On the other hand, anchor bolts 21 are installed at intervals on the concrete base 20 on which the heat insulating floor unit 10 is installed. Install the insulation floor unit LO as follows.

A sheet waterproof layer 18 is pasted on the bottom of the heat insulating floor unit 1O, and the notches 23 of the flange portion 14 of the heat insulating floor unit 10 are aligned with the anchor bolts 21 of the concrete base 2o.
A heat insulating floor unit 1o is installed on a concrete base 20. A presser plate 15 with bolt holes 22 formed at intervals is placed on the adjacent flange portion 14, and the nuts are tightened. After that, drain water I! A heat insulating material 22 is filled leaving a space forming a hole 19. A sheet waterproof layer 1B is attached to the upper edge of the adjacent steel plate frame J1 and the upper side wall, and a gutter 1 is attached to the upper space of the heat insulating material 22.
form 9. Upper part of the insulation floor unit IO (top plate 12)
A snow mat 23 is spread on the drainage gutter 19. Note that the shape of the heat insulator unit IO is not limited to a rectangular parallelepiped.

[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 frame has a top plate, even if water leaks from the drainage gutter, water will not enter the frame. In addition, even if moisture gets into the frame, the insulation capacity will not deteriorate because the moisture-proof layer with aluminum foil that wraps around the outer periphery of the insulation prevents moisture from entering.

(3) Since a heat insulating layer is simply provided on a steel plate frame, it is easy to produce a heat insulating floor unit.

(4) Since the insulating floor can be manufactured in a factory, the insulating floor can be installed in an indoor ski resort in a short period of time.
