ある。[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to an athletic field made of artificial turf, and more specifically, to an athletic field made of artificial turf that can also be used as an ice skating rink.

The idea of using all-weather painted athletic fields (e.g. tennis courts, soccer fields, hockey fields, etc.) as ice skating rinks in winter has been studied from various angles and experiments have been conducted. For these reasons, this has not yet been achieved.
すなわち、競技場の地下部に常時冷却パイプを

あり、施工が容易とは言えない。 In other words, it would be ideal to permanently bury cooling pipes underground in the stadium and make ice simply by sprinkling water in the winter, but in the case of all-weather painted sports stadiums, the surface finishing material is a poor thermal conductor. Therefore, it is extremely difficult to realize. Therefore, as seen in Japanese Patent Publication No. 51-49506, for example, a room-temperature paving agent has been developed in which a curing agent is mixed into a urethane resin prepolymer and metal powder with good thermal conductivity is added to improve the thermal conductivity. It was proposed that the paving material be installed on a hard base, but depending on the type of stadium, it would be necessary to change the composition of the urethane resin prepolymer and curing agent to adjust the physical properties of the room-temperature paving material to suit the sport. It cannot be said that construction is easy.

備期間を要する、等の問題点がある。 As an alternative to this underground method, there is a method of making ice by temporarily installing cooling pipes on the surface of the stadium, but this requires a large amount of money to install and remove the cooling pipes, and also requires a large storage space when not in use. There are problems such as damage to pipes during installation and removal, large refrigerant tanks and large consumption of refrigerant, difficulty in maintaining homogeneous and high-quality ice, and considerable preparation time required for conversion. be.

This idea focuses on athletic fields made of sand-filled artificial turf, which have recently become widespread, and allows these sand-filled artificial turf athletic fields to be used as ice skating rinks through simple modifications. It consists of a cooling layer containing cooling pipes for the refrigeration cycle on the upper layer of the base layer, which is made of sand-containing artificial grass that is filled with sand containing thermally conductive materials such as metal powder and metal fibers. The system uses a cooling pipe to freeze the water sprinkled on the artificial lawn.

Artificial lawns are made by planting leaf pieces of polypropylene, nylon, vinylidene chloride, etc. on a thin base fabric (usually about 1 mm thick), and because the leaf pieces are oriented in the direction of conduction, they can be used in all weather conditions. It has much better thermal conductivity than finishing materials. In addition, the sand filled in the grass grains occupies most of the volume, but this sand is also a good thermal conductor, and metal powder and metal fibers with high thermal conductivity are mixed in the sand. Cooling efficiency is increased and ice can be made efficiently.
