Description

  The present invention relates to a stadium including an arena and a stand disposed on the periphery of the arena.

  Conventionally, as this type of stadium, there are many arenas in which natural turf is planted, and the planar shape thereof is, for example, a substantially rectangular shape (see, for example, Patent Document 1). In addition, the stand provided around the arena has a long side stand corresponding to the long side of the arena and a short side stand corresponding to the short side, and in the places corresponding to the four corners of the arena, A space serving as a break between the long side stand and the short side stand is formed, and this space is used as a passage that can be used for entering and exiting the arena, for example.

JP-A-9-177342 (FIG. 1)

In order to maintain the growth of the natural turf planted in the arena, it is important to secure a growth environment that does not inhibit the natural turf photosynthesis as well as maintenance such as watering and fertilization. Therefore, sufficient sunshine and appropriate ventilation are essential conditions.
Especially for ventilation, in addition to the action of supplying carbon dioxide to the turf, it also has the action of removing water films and water droplets that adhere to the surface of the turf and interfere with the supply of carbon dioxide. It is preferred that

According to the conventional stadium described above, with regard to sunshine on the turf, if the upper part of the arena is open or if it is made of translucent roofing material, the sunlight is irradiated onto the turf surface without being blocked. A preferable light receiving environment is easily prepared.
However, with regard to ventilation to the turf, according to the passages formed at the four corners of the arena, depending on the wind direction, the wind may not enter the passage, and even if the wind direction is good, the wind hitting the corner of the stadium is not in the passage. Since it is easy to escape, it is difficult for the wind to reach the arena through the passage, and air tends to stagnate on the grass surface of the arena except during strong winds.
As a result, there is a problem that a sufficient ventilation environment cannot be obtained over the entire area of the turf of the arena.

  Accordingly, an object of the present invention is to provide a stadium that solves the above-described problems and provides a ventilation environment for the entire area of the turf of the arena.

  A feature of the present invention is a stadium comprising an arena and a stand arranged on the periphery of the arena, and in plan view, a plurality of communication between the outside of the stand and the arena in a state in which ventilation is possible. These communication paths are provided in correspondence with the respective sides of the arena in a state of passing through the lower space of the stand.

According to the present invention, since a plurality of communication paths are provided corresponding to each side of the arena in plan view, it is possible to distribute the communication paths to the arena over the entire circumference of the arena. The wind blowing outside the stadium will be accepted by the arena from a wide range corresponding to each side of the arena. Therefore, it becomes easy for the wind to enter the communication path, and regardless of the direction of the wind, the outside of the stand and the arena can be ventilated through the communication path corresponding to the wind direction. In addition, if the wind direction changes, ventilation to the arena can be performed through another communication path corresponding to the wind direction.
In addition, since each communication passage is provided in a state of penetrating the space below the stand, the opening on the arena side of the communication passage is located at a height close to the top surface of the arena, and ventilation to the arena is efficient. Can be implemented well.
As a result, ventilation is not biased near the four corners of the arena as in the prior art, but a ventilation environment is provided in which sufficient ventilation is possible over the entire arena.
Therefore, the preferable growth environment with respect to the natural grass of an arena can be provided.

  In the present invention, in the lower space of the stand, a living room zone in which a plurality of living rooms are arranged along the side of the arena is formed, and in the living room zone, between the adjacent living rooms. It is preferable that the communication path is disposed.

In general, when a living room zone is formed in the space below the stand, the living rooms are connected to each other without a gap, and therefore it is difficult to form the communication path in that portion.
However, according to this configuration, since the communication path is arranged between the rooms provided adjacent to each other in the living room zone, the communication path can be provided while maintaining the function as the living room zone. it can.
As a result, it is possible to provide many communication paths on the sides of the arena, and it is possible to construct a fine ventilation environment for the arena. Further, the communication path itself can be used as a zoning means in the living room zone.

  In the present invention, it is preferable that the living room zone has a plurality of living rooms arranged vertically.

As the communication path is arranged between the adjacent rooms in the living room zone, there is a concern that the area occupied by the living room in the living room zone may decrease, but according to this configuration, by arranging a plurality of living rooms up and down, A communication path can be secured without reducing the total area of the room in the room zone.
As a result, it is possible to secure a plurality of communication paths without deteriorating the function as a living room zone by effectively using the space.

  In the present invention, it is preferable that the communication path is connected at the same level as the arena.

According to this configuration, since the opening on the arena side of the communication path is located at the same level as the arena, it is difficult to make a large step in the ventilation flow path leading to the communication path and the arena, and in the ventilation through the communication path Air flow loss can be reduced, and the efficiency of ventilation over the arena can be further improved.
Therefore, even when the wind speed in the surroundings is low, ventilation of the arena to the natural turf can be performed in a preferable state.

  In the present invention, it is preferable that the arena, the ground surface outside the stand, and the communication path are formed at the same level.

According to this configuration, the linear shape of the series of flow paths that communicate the outside of the stand and the arena through the communication path can be configured to have a very simple shape at the same level, further reducing the flow loss of the ventilation air. Can be small. Therefore, even if the surrounding wind is light, it can be efficiently reflected in the ventilation of the arena.
Also, in the construction of the stadium, it is no longer necessary to dig deep into the arena, and it is possible to shorten the construction period and reduce costs by reducing the number of ground excavation man-hours.
