Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ice-

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a freezing facility for ice-link and a construction method thereof, and more particularly, to a freezing facility and a construction method capable of perfectly keeping ice sheets of the ice-bridge horizontally.

Generally, the ice rink is constructed by laying a moisture-proof film on a concrete slab, installing a 100 mm-thick styrofoam insulation material, then dampening a film again, placing a cooling pipe support and reinforcing bars for fixing, and then pouring the concrete once Construction.

However, even if we compare only the short track stadium, we will use double reinforcing bars of 13mm or 25mm disconnection to fix the international standard (30m × 61m) cooling pipe. In this case, the weight of the reinforcing bar reaches 20ton and heavy load is applied to the slab There is a problem that many workers are forced to work on the cooling pipe and the rebar when the concrete is poured, and thus there is a problem that the horizontal and the separation distance of the cooling pipe, which is an important part of the freezing facility, can not be maintained.

In addition, there is a limitation that it is difficult to horizontally form a large area surface due to a single concrete pouring, and there is a problem in that it is difficult to secure the horizontal level of ice, for example, the thickness of ice is different for each position.

In case of ice link, HDPE (high density polyethylene) is used as a cooling pipe. Even if the horizontal, vertical, and separation distance are correctly adjusted during piping construction, HDPE material is used in final concrete pouring work. And the distance can not be maintained. As can be seen from the actual installation work in the field, it can be seen that the irregularity of the reinforcing bar or the cooling pipe becomes a curved shape.

Once the concrete pouring work is done, there is no stopping, so there is a disadvantage that the work must be carried out even if the irregularity of the reinforcing bar or the cooling pipe becomes a curved shape.

Because of the nature of the ice rink, it may be necessary to preserve semi-permanently unless the link site is closed after completion of the facility, which may not be the case.

In this case, if the horizontal, vertical, and separation distances are not maintained, the operation of the electric motor such as a freezer, which is a necessary equipment of the freezing facility, becomes frequent and the lifetime of the device can be shortened.

In addition, performance of equipment such as a freezer is deteriorated, and a large amount of maintenance expenses such as repair costs are generated.

In the case of ice rinks, it is essential to maintain the horizontal, vertical and spacing of the cooling pipes even for the ice quality required by the Olympic Committee.

Currently, a universal construction method for ice-freezing facilities is as follows.

5A and 5B, a moisture-proof film 100a is installed on a concrete slab, a styrofoam heat insulation material 110 is installed, a moisture-proof film 100b is installed, a reinforcing bar 13mm double- or 25mm single- Installation of pipe 130, installation of concrete 140 (90 mm), and freezing after filling of water.

Here, the reference numeral 150 denotes a spacer for supporting the reinforcing bars.

Here, the moisture-proof film is used to spray water during the first freezing operation, so as to prevent penetration of water at the bottom, and then to block the moisture that the cold air has.

However, if a moisture-proof film (vinyl) of 0.5 mm is used, even if the cleanliness is maintained at the site, a hole may be formed in the fine dusty sand, and the work is performed at a minimum link area of 1,830 m 2 or more. Naturally, the rate at which cold air, including moisture from the cooling tube and the ice surface, is transmitted downward is increased.

In this case, when cold air having an average temperature of about -8 ° C is continuously supplied to the lower portion, the slab is frozen and the central portion of the slab rises.

A boiler or the like is installed as a means for preventing the slab from being frosted, and a separate heating pipe is installed to prevent frostbite.

Insulation is a means to prevent cold air from moving downward. It is installed with double layer of 50mm thick insulation, and the joints are staggered from each other. Because of the characteristic of ice link consuming a lot of energy, insulation is an important part in freezing facilities .

Generally, in the case of ice-lining, the first moisture-proof film is covered on the slab and the styrofoam 100 mm is applied on the slab. In this case, 50 mm is divided into two layers, and the first 50 mm and the second 50 mm are staggered and the heat- Will use the butt method.

In this case, the number of joints increases and a layer between the primary insulation and the secondary insulation is generated, so that the buffering action causes a phenomenon that the ice surface is cracked.

In addition, the cold and moisture remain in the layer, and when the time passes, the cold air and the moisture eventually reach the slab and the slab is frozen.

The steel reinforcement is used to fix the height of the insulation with the means of fixing the cooling pipe.

In addition, the height of the concrete reference surface 19 can be adjusted. For example, a concave / convex portion 23e in the vertical direction is formed on the side surface of the body of the concrete installation surface reference member 19, Since the concave and convex portion 23e at this time is selectively hooked to the vertical concave-convex portion 23c on the inner surface of the wall of the bar member 13, the height of the concrete placement surface reference member 19 can be adjusted do.

Accordingly, when the reference of the secondary concrete placement surface is set, the height of the entire concrete placement surface reference member 19 is roughly adjusted using the concave / convex portion 23e of the concrete placement surface reference member 19, The height of the entire concrete-laid surface reference member 19 can be adjusted in such a manner that the height of the concrete-laid surface reference member 19 can be matched with the height of the concrete pouring surface 18, and as a result, .

A plurality of cooling pipe fixing members 16 and a concrete installation surface reference member 19 are installed on the bar member 13 and the bar member 13 is provided with the styrofoam heat insulating material 10 and the bar member 13, The primary concrete layer 20 is formed by the concrete placed on the basis of the upper end (lid surface) of the concrete reference surface 19 and the concrete placed on the basis of the indicator 18 of the concrete installation surface reference member 19 Since the car concrete layer 21 is formed, a base of the ice link freezing facility can be provided.

A construction method of the ice-link freezing facility constructed as described above will be described below.

4 is a cross-sectional view illustrating a method of constructing an ice link freezing facility according to an embodiment of the present invention.

When the styrofoam heat insulating material 10 is installed, a moisture-proof film 24 made of a straight film is adhered to the upper, lower, or upper surfaces of the styrofoam heat insulating material 10 to prevent cold air from escaping to the lower slab side .

Next, a plurality of bar members 13 having an inner space 11 and an openable lid 12 are arranged on the styrofoam heat insulating material 10 at regular intervals.

That is, the bar members 13 of the respective columns integrally connected by the gap holding member 25 are placed on the styrofoam heat insulating material 10 and arranged.

The bar member 13 is connected to a plurality of spacing members 25 so as to maintain a gap therebetween and a plurality of brackets 22 are mounted. The bar member 13 is selectively engaged with the vertical irregularities 23a on the inner surface of the wall of the wall 22 in the vertical direction so that the irregularities 23b on the outer surface of the wall of the bar member 13 are selectively engaged. To adjust the horizontal height.

Then, the first concrete layer 20 is constructed by placing the concrete in a state that the upper part of the bar member 13 provided with the horizontal height is closed by the cover 12.

At this time, the placement of the primary concrete layer 20 is aligned with the upper surface of the lid 12 of the bar member 13, so that the level of the primary concrete layer 20 can be accurately aligned.

Next, after curing of the primary concrete layer 20, a step of installing a plurality of cooling tube fixing members 16 in the bar member 13 with the lid 12 removed is performed.

That is, a plurality of cooling pipe fixing members 16 are installed at regular intervals along the longitudinal direction of the bar member 13.

At this time, each cooling pipe fixing member 16 is installed in such a manner that the concave-convex portion 23d on the side of the body is selectively engaged with the concave-convex portion 23c on the inner surface of the wall of the bar member 13, The height of the cooling pipe fixing member 16 is adjusted.

Here, when the height of the cooling pipe fixing member 16 is adjusted, a laser beam is irradiated to the laser leveler to align the top of the clip with the laser light.
