Description

[Detailed description of the invention] <Industrial application field> The present invention relates to an ice skating rink.

<Prior Art> In permanent ice skating rinks, refrigerant piping is buried in the concrete floor, and in temporary ice skating rinks, refrigerant piping is exposed above the floor.

<The problem that the invention seeks to solve> However, in conventional permanent ice skating rinks, if the concrete layer is leveled, there is a risk of expansion of damage due to corrosion or freezing of the pipes, so it is difficult to use the ice skating rink in the off-season. In a temporary ice skating rink, installation and removal of refrigerant piping is time-consuming and costly.

Means for solving the origin of gaps> The present invention provides a large number of pillars protruding from one side of a rectangular net-like object, and a rectangular mesh with long oblong pillars on two adjacent side edges in the direction perpendicular to the side edges. A unit plate is provided with a ring protruding from it, and a protrusion with an outer diameter approximately equal to the inner minor axis of the ring is attached to the remaining two side edges, and the protrusion is fitted onto the ring of another unit plate on the floor surface. This problem is solved by placing a large number of connected unit plates on the floor, freezing the unit plates on the floor, and then shaping the ice layer in which the unit plates are embedded.

Next, an example of the present invention will be explained based on the drawings.

Since the present invention is based on the premise of using a unit plate with a specific structure, the structure of the unit plate will be explained first.

The unit plate Pfi is made of a rectangular, ie, right-angled rectangular polyolefin-based synthetic resin mesh board, and the dark side of the mesh 1 is a through hole 2. A plurality of rings 3 are provided on the outer periphery of the two adjacent side edges to protrude laterally, and the inside of the ring 3 has an oval-shaped through hole 4 extending in the direction perpendicular to the side edge and penetrating the square plate in the thickness direction. It is equipped with

A protrusion 5 is attached to the back surface of the remaining two side edges of the unit plate from which the ring 3 is not protruded. The protrusion 5 Fi is attached corresponding to the position of the ring 3, and when the unit plates are lined up, the protrusion 5 is located at the ring 3. It has a hollow cylindrical shape, and its outer diameter is the inner minor axis of the ring 3. They are almost equal.

On the back side of the unit plate, in addition to the protrusion 5, struts 6.7 and 8 are attached at the intersections of the meshes 1. The six columns have a cylindrical shape and have a large outer diameter, and the length thereof is substantially equal to the length of the protrusion 5.

The support column 7 is cylindrical, has a smaller outer diameter than the support column 6, and is also slightly shorter in length. The pillars 8 are attached to the green part of the square plate, and are shaped like pillars 6 or 7 divided into two in the vertical direction, with one having a large outer diameter and a long length 81 and the other having a small outer diameter and a long length. The short one is 82. Supports 6 and 7 and support 81
and 82 are attached alternately.

To connect the unit plates, place the side edge of the unit plate P-2 with the ring 3 against the side edge of the unit plate P-1 on which the protrusion 5 is attached, and then the protrusion 5 Since the protrusions 5 are provided corresponding to the positions of the rings 30, the protrusions 5 can be fitted into the rings 3 at positions close to the rings 3, and the unit plates can be connected one after another.

In the connected unit plates, the support 7 is shorter than the support 6, so the support 7 is in a floating state on a plane, and when the board is stepped on, the rectangular plate slightly lowers at the support 7.

Therefore, the square plate exhibits good cushioning properties. In the case of a temporary ice skating rink where the refrigerant piping is exposed above the floor, the piping is housed in the space between the supports 6, 7 or Vis, and the protrusion 5 is connected to the ring 3 of the other unit plate. Place the connected unit board on the floor, sprinkle a little water on it, freeze it, and then freeze the unit board on the floor. Shape the layers.

As in the above embodiment, it is preferable to form the unit plate into a mesh shape, since air bubbles escape upward when the ice layer is formed, making it difficult for the ice layer to float upward.

In order to reduce the mixing of air into the ice layer, a surfactant may be mixed into the raw material synthetic resin of the unit plate, or a surfactant may be mixed into water.

Effects of the Present Invention The present invention is designed as described above, and since the unit plates are visible through the ice layer, they can be used for delineating the court by partially changing the color of the unit plates. At the same time, during the off-season, refrigerant pipes are left exposed on the floor of temporary ice skating rinks and can be used as tennis courts, etc., while permanent ice skating rinks do not damage concrete floors. It can be used as a tennis court, etc.
