Abstract

PURPOSE:To prevent deviation of floor component members by nut-fastening a heat insulated floor unit, in which a concrete layer is superposed on a heat insulator layer interiorly of a steel-plate made frame, to an anchor bolt of a concrete base via a heat insulative short-column like bolt. CONSTITUTION:A bottom steel plate 24 of a rectangular parallelopiped frame is formed, at its outer periphery, with a lower side wall 25, and a horizontal flange 23 is formed in such a manner as to extend inwardly from an upper end of the lower side wall 25. Then, an upper side wall 26 is formed on an inner edge of the flange 23, thus forming a steel-plate made frame 11. Next, a heat insulator layer 12 prepared by bonding an aluminum-foil coated moistureproofing layer 13 onto the upper surface of heat insulator, and a pressing concrete layer 14 clad with a sheet waterproofing layer are provided inside the frame 11 to construct the heat insulated floor unit 10. This unit 10 is placed on a concrete base 20. And a heat insulation short-column like bolt 19 which is attached to an anchor bolt 16 of a concrete base 20, is nut-fastened to a pressing plate on the adjoining flange 23 for fixation of the unit 10.

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. 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 ski resort 1 has pillars 3 erected on 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°C, and uses a snow machine to deposit about 20 to 50 an 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, the floors of indoor ski resorts are covered with snow mats (artificial turf-like material made of short fibers flocked to drainage mats) to prevent snow from slipping, and waterproof sheets that form drainage gutters. has been
Pile snow 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 and enters the insulation material, the insulation ability of the insulation floor will decrease. must be moisture-proofed. 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.

(1) The insulating floor must be installed at an incline, and the inclination must not cause any 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) The insulation floor can be installed in a short period of time.

[Means for Solving the Problems] The present invention aims to provide a heat insulating floor structure for an indoor artificial ski resort that satisfies the above conditions, and includes a lower side wall extending upward from the outer edge of a rectangular bottom steel plate. forming a flange extending horizontally inward from the upper edge of the lower sidewall;
A steel plate frame is formed with an upper side wall extending upward from the inner edge of the flange, and a heat insulating material layer is provided on the lower side wall inside the steel plate frame with an aluminum foil-covered sheet vapor barrier layer adhered to the upper surface of the heat insulating material. A heat insulating floor unit is constructed by providing a holding concrete layer with the upper edge, side wall and bottom covered with a sheet waterproof layer inside the upper side wall, and the insulation is attached to anchor bolts planted at intervals in the concrete base. This is an insulated floor structure for indoor artificial ski resorts, which is characterized by tightening nuts through short columns.

[Function] Since the heat insulating material layer and the holding concrete layer are housed in a steel plate frame having a bottom plate, there is no deviation between these floor components even when installed on an inclined surface.

In addition, since a sorted moisture-proof layer with aluminum foil is attached to the top surface of the heat insulating material, even if water enters through the holding concrete layer, water will not penetrate into the heat insulating material.

Since the heat insulating floor unit is attached via short heat insulating columns, the amount of heat transfer can be suppressed.

[Embodiments] Examples of the present invention will be described below based on the drawings. The insulating floor of the present invention has a plane size of 3 to 10 m (vertical) x
They are built 3 to 10 meters (horizontally) and are installed side by side on the concrete base 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 10 installed on a concrete foundation, and a drainage gutter 22 for draining snowmelt water is provided between the insulating floor 10 installed side by side and the adjacent insulating floor IO. ing.

The heat insulating floor unit IO has a lower side wall 25 extending upward from the outer edge of a rectangular bottom steel plate 24, a flange 23 extending horizontally inward from the upper edge of the lower side wall 25, and a lower side wall 25 extending upward from the inner edge of the flange 23. A heat insulating material in which a steel plate frame 11 with an extending upper side wall 26 is formed, and a sheet vapor barrier layer 13 with aluminum foil is attached to the upper surface of a heat insulating material (polystyrene foam, etc.) on the lower side wall 25 inside the steel plate frame 11. The upper side wall 26 is provided with a holding concrete layer whose upper edge, side wall, and bottom are covered with a sheet waterproof layer. On the other hand, a heat insulating short post (made of polyacetal resin) 17 is screwed and attached to the anchor port 16 planted in the concrete base 20, and a stud bolt 19 is inserted into a screw hole carved in the upper part of the heat insulating short post 17. is screwed in and installed. To install the heat insulating floor unit 10 on the concrete base 20, place the heat insulating floor unit 10 on the concrete base 20,
This is done by passing the bolt hole of the presser plate 18 through the stud bolt 19 onto the flange 23 of 0, and tightening the nut. Thereafter, a sheet waterproof layer 21 is attached to the upper part of the adjacent heat insulating floor unit 10 to form a drainage gutter 22. And the upper surface of the insulation floor unit 1O and the drainage 1!2
A snow mat 15 is pasted on the top of 2. Note that the shape of the heat insulating floor unit may be such that the bottom surface thereof is hexagonal.

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

('l) Even when installed on an inclined surface, the insulation floor component does not shift.

(2) Since the outer periphery of the holding concrete is covered with a sheet waterproof layer, even if water leaks from the drainage gutter, water will not flood into the lower part of 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 the heat insulating floor unit is attached via the heat insulating short pillars, the amount of heat transfer can be suppressed.

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