Description

  The present invention relates to a stadium including an arena, a stand disposed on a peripheral portion of the arena, and a roof portion that opens on the arena and covers the top of the stand.

Conventionally, in this type of stadium, the roof is supported on a roof frame that forms a downwardly inclined roof surface from the front side of the stand (the arena side) to the back side of the stand (the outside of the stadium), and the roof frame. Some roof panels are provided (see, for example, Patent Document 1).
In addition, the roof plate is attached to the roof frame so as to be movable along the inclination of the roof surface, and the roof plate is moved to the rear side of the stand by using a drive device such as a winch. The shadows of the can't fall on the arena, so that the grass of the arena could be nurtured.

JP-A-8-277743 (FIGS. 3 and 7)

While the roof has a function of shielding direct sunlight and rain on the stand, etc., the arena where the turf is installed is required not to impede solar radiation. In many cases, the front end line of the roof portion is provided near the boundary between the stand and the arena.
In addition, since the roof plate is installed on a large roof frame made of beams, the vertical distance between the top surface of the arena and the front edge of the roof plate (hereinafter simply referred to as “the height of the roof plate”) is a considerably large value. It becomes.

As a result, when sunlight is irradiated obliquely from the top of the roof toward the arena, a shaded area that correlates to the "roof height" will occur at the edge of the stand in the arena, It tends to be an obstacle to nurturing grass on the arena.
On the other hand, if there is rainfall that blows diagonally from the top of the arena toward the stand, a blow-down area that correlates to the “roof height” will be generated at the edge of the stand on the arena side. Will get wet.

According to the conventional stadium described above, the shade area generated in the above arena can be reduced by moving the roof plate to the lower side along the roof slope.
However, in order to do so, in addition to the need for equipment such as rails and driving devices for moving the roofing board, it takes time and effort to move the roofing board, resulting in economic efficiency including initial costs and running costs. There is a problem.
In addition, there is a problem that the effect cannot be expected with respect to the decrease in the downwind area.

  Accordingly, an object of the present invention is to provide a stadium that solves the above-mentioned problems and can economically realize the reduction of the shaded area generated in the arena and the reduction of the downwind area generated in the stand.

  A feature of the present invention is an athletic field comprising an arena, a stand disposed on a peripheral portion of the arena, and a roof portion that opens above the arena and covers the stand. The portion is configured to include a roof plate and a roof beam that supports the roof plate, and the roof plate is disposed below the roof beam, and in a front region located on the arena side. And a translucent roof portion having light transmissivity.

According to the present invention, since the roof plate is disposed under the roof beam, when the installation height of the roof beam is the same as the conventional one, the “roof plate height” is made smaller than the conventional case. be able to.
Therefore, the downflow area correlated with the “roof height” can also be made smaller than in the conventional case.

Further, in addition to the decrease in the shaded area due to the decrease in the “roof plate height”, in the front region located on the arena side of the roof plate, having a translucent roof portion having light transmittance, The shade area can be further reduced.
As a result, it has become possible to economically realize an environmental improvement in the turf cultivation of the arena and an improvement in the watching environment on the stand.
Furthermore, since the bottom surface of the roof portion can be made flat so that the roof beams do not protrude, the landscape when the roof portion is looked up from the stand can be made orderly and the aesthetics can be improved.

  In the present invention, the roof girder includes a front roof girder laid in a longitudinal direction in a direction along a front end line of the roof plate, and the front roof girder is on the rear end side with respect to the front end of the roof plate. It is preferable that they are arranged apart from each other.

According to this configuration, the front roof girder is arranged so as to be separated from the front end of the roof plate to the rear end side, so that the roof plate can be supported by the front roof girder and is provided in the front region of the roof plate. When sunlight is irradiated to the arena side through the translucent roof part, the shadow of the front roof beam is less likely to be generated in the arena, and it is easy to maintain a good environment for cultivating the arena's turf.
In addition, when looking at the roof on the opposite side across the arena from the stand, the front roof girder of that roof has been retracted to the back side, so the degree of exposure to the front becomes low, and the aesthetics deteriorate. Can be prevented.

  In the present invention, it is preferable that the translucent roof portion is provided on a roof portion located on the solar locus side in a plan view.

Of the roofs surrounding the arena, the roof part located on the solar trajectory side in plan view is in a position where it is easy to create a shadow of sunlight on the arena throughout the day. Specifically, it is a roof portion located on the south side in the northern hemisphere, and a roof portion located on the north side in the southern hemisphere.
According to this structure, since the translucent roof part is provided in the roof part located in the solar locus | trajectory side in planar view, irradiation of the sunlight through a translucent roof part can be anticipated, and it is on the arena all day. It is easy to prevent a region where sunlight is not irradiated.
As a result, it is possible to efficiently improve the environment for turf growth in the arena.
