Description

[Technical Field]

[0001] The present invention relates to a facility for hosting various sports events such as soccer, baseball, and track and field, as well as various events such as concerts, exhibitions, and trade fairs. More specifically, it relates to a multi-purpose stadium that utilizes both an above-ground field and an underground space, and in which some of the stands (spectator seats) can be raised and lowered to allow the stands to be used both as the field and the underground space. [Background technology]

[0002] A stadium is a facility designed for the purpose of playing a specific sport or for spectators to watch that sport, with baseball stadiums and soccer stadiums being typical examples. However, the number of sports (e.g., number of matches) held at stadiums is generally only a few dozen per year, making it currently difficult to generate stable revenue throughout the year.

[0003] The Japan Sports Agency has therefore decided to provide financial support for the formulation of stadium and arena development plans through public-private partnerships, and is promoting the development of multi-functional, complex facilities that can regularly host events other than sports, with an emphasis on profitability.The government has also set a goal of building multi-functional, complex stadiums and arenas nationwide by 2025, with an emphasis on profitability.

[0004] Multipurpose stadiums that can be used for baseball, soccer, concerts, and other events are extremely advantageous in terms of revenue because they can attract customers constantly throughout the year, and various proposals have been made regarding multipurpose stadiums. For example, Patent Document 1 proposes a two-story facility that can be used for multiple purposes, with a two-story structure consisting of a base floor and a movable floor that can be raised and lowered, and when the base floor is used, the movable floor is raised to a predetermined position, and when the movable floor is used, the movable floor is lowered to the base floor. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Publication No. 2022-20188 Summary of the Invention [Problem to be solved by the invention]

[0006] The two-story facility disclosed in Patent Document 1 has a raised and lowered working floor, which means that the sky above is wide open when the working floor is in use, as well as when the base floor is in use, allowing for a wide range of competitions and events to be held without much restriction. However, because a device is required to raise and lower the working floor, and a structure is also required to support the raised working floor, the construction and operation of a large-scale facility will incur considerable costs.

[0007] One solution is to use two floors, one above the other, without raising the ground floor. For example, a field could be built on the ground, and an underground space could be built directly below it. In this case, the field would not be raised or lowered, so there would be no need to install lifting devices. This would be ideal because designated sports (such as soccer or track and field) could be held on the field, and designated sports (such as basketball or volleyball) or various events (such as concerts) could be held on the floor in the underground space (hereinafter referred to as the "event floor").

[0008] However, seating is usually set up around the field, and also around the event floor in the underground space, which necessitates the installation of a large number of seats, which increases the cost of constructing the seats.

[0009] The objective of the present invention is to solve the problems of the prior art, that is, to provide a multi-purpose stadium that can utilize two levels of space, above and below ground, and in which some of the seating can be used by both the upper and lower levels. [Means for solving the problem]

[0010] The present invention was developed with a focus on the fact that some of the seats move diagonally between the above-ground and underground spaces, and is an invention based on an unprecedented concept.

[0011] The multipurpose stadium of the present invention comprises a field located above ground, fixed stands, an underground space, underground stands, and movable stands. The underground space is located below the field, and an underground floor is formed beneath it. The fixed stands have multiple tiers of seats arranged in a manner that rises away from the field, the underground stands have multiple tiers of seats arranged in a manner that rises away from the center of the underground floor, and the movable stands have multiple tiers of seats arranged at an incline. An opening is provided in the underground space, and the movable stands can move up and down along the incline of the movable stands while passing through this opening. The seats are arranged so that they rise away from the field when the movable stands rise to the field surface, and so that they rise away from the center of the underground floor when the movable stands descend to the underground floor.

[0012] The multipurpose stadium of the present invention may further include two or more slope supports. These slope supports are installed underground and are inclined approximately parallel to (including parallel to) the slope of the mobile stand. In this case, the mobile stand moves up and down while sliding on the slope supports.

[0013] The multipurpose stadium of the present invention may further comprise an earthen support structure for supporting the fixed stands, which is formed using the excavated soil from the underground space. [Effects of the Invention]

[0014] The multi-purpose stadium of the present invention has the following advantages: (1) Since some of the seating can be used by both the upper and lower spaces, the cost of constructing the seating can be reduced. (2) Various sports such as soccer, baseball, and track and field can be held on the aboveground fields, and various events such as concerts, exhibitions, and product fairs can be held in the underground space. As a result, the utilization rate of the multi-purpose stadium will increase. (3) If the earthen embankment supports that support the fixed and movable stands are formed using the soil excavated when the underground space is excavated, the costs of transporting the soil and disposing of the remaining soil can be significantly reduced, which means that the overall cost of constructing a multi-purpose stadium can be reduced.

[0016] An example of an embodiment of the multipurpose stadium of the present invention will be described with reference to the drawings. FIG. 1 is a plan view schematically illustrating the multipurpose stadium 100 of the present invention. As shown in this figure, the multipurpose stadium 100 of the present invention comprises a field 200 and stands arranged around the field 200. This field 200 can be configured for various sports such as soccer, baseball, rugby, and track and field, but for convenience, the following description will use the example of a soccer field 200. The multipurpose stadium 100 of the present invention allows the use of the field 200 and the space constructed below it (hereinafter referred to as the "underground space 800"), making it a facility that allows the use of two upper and lower levels of space. For convenience, the ground surface on which the field 200 is formed will be referred to as the "base surface."

[0017] The stands that make up the multipurpose stadium 100 are made up of "fixed stands 300" that are fixed on the base surface (i.e., they do not move) and "mobile stands 400" that move up and down between the base surface and the underground space. In other words, some of the stands that make up the multipurpose stadium 100 are mobile stands 400, and the rest are fixed stands 300. For example, in the multipurpose stadium 100 shown in Figures 1 and 2, the area behind the soccer goal SG on one side (e.g., the away side) is made up of mobile stands 400, and the main stand, back stand, and side stand on the other side (e.g., the home side) are made up of fixed stands 300. Of course, the locations of the mobile stands 400 can be selected as appropriate, such as making the other side stand a mobile stand 400, making part of the back stand a mobile stand 400, or making both side stands a mobile stand 400.

[0018] Below, each of the main elements that make up the multipurpose stadium 100 of the present invention will be described in detail.

[0019] (Fixed stand and mobile stand) The fixed stand 300 is arranged facing the field 200 as shown in Fig. 1, and has multiple tiers of seating. However, the seats in the fixed stand 300 are arranged so that they rise as they move away from the field 200 (i.e., toward the outside of the multipurpose stadium 100) as shown in Fig. 2. On the other hand, the movable stand 400 is also arranged facing the field 200, and has multiple tiers of seating arranged at an angle. Therefore, the movable stand 400, which is arranged on a base surface as shown in Fig. 2, has multiple tiers of seating that rise as they move toward the outside of the multipurpose stadium 100, just like the fixed stand 300. In the example of Figure 2, the left side stand is the movable stand 400, and the right side stand, main stand, and back stand are the fixed stands 300, but as mentioned above, the location of the movable stand 400 can be selected as appropriate, such as making the right side stand 400 the movable stand 400, making part of the main stand or back stand the movable stand 400, making both side stands the movable stand 400, or making one side stand and part of the back stand the movable stand 400.

[0020] (underground space) 3 is a diagram showing a schematic diagram of an underground space 800, where (a) is a vertical cross-sectional view of the underground space 800 at the position where the fixed stand 300 is installed, and (b) is a vertical cross-sectional view of the underground space 800 at the position where the mobile stand 400 is installed. As shown in this figure, the underground space 800 is a space provided below the field 200, and can be formed, for example, by a "floor slab 810" as a bottom slab, a "top slab 820" as a ceiling slab, and "side walls 830" as side slabs.

[0021] The underground space 800 has an underground floor surface 600 formed on its bottom surface (for example, the top surface of the floor slab 810), and furthermore, in the center of the underground floor surface 600, a space (hereinafter referred to as the "sports area" for convenience) is formed for holding various sports such as basketball and volleyball, or events such as concerts and product exhibitions.

[0022] 4, underground stands 700 are installed on the underground floor surface 600 and are arranged facing the playing area, for example. The underground stands 700 are also provided with multiple levels of seating, and these seats are arranged so that they rise as they move away from the playing area (i.e., towards the outside of the underground space 800).

[0023] As shown in FIG. 3(a), the underground stand 700 is installed in the area of ​​the underground space 800 where the fixed stand 300 is installed above it (hereinafter referred to as the "fixed area" for convenience). In contrast, the underground stand 700 is not installed in the area of ​​the underground space 800 where the mobile stand 400 is installed (hereinafter referred to as the "mobile area" for convenience) so that the mobile stand 400 can be installed there instead. In other words, the fixed area of ​​the underground space 800 is where the underground stand 700, which does not move, is installed. Furthermore, the mobile area of ​​the underground space 800 is left as an empty space when the mobile stand 400 is installed on the base surface, and the mobile stand 400 is installed there when the mobile stand 400 descends.

[0024] As described above, the mobile stand 400 moves up and down between the basement surface and the underground space 800. Therefore, an opening 500 through which the mobile stand 400 can pass is provided in the underground space 800, as shown in Figures 2 and 3(b). For example, the underground space 800 shown in Figure 3(b) has an opening 500 formed in a part of its side wall 830, and the mobile stand 400 can enter the underground space 800 through this opening 500, and can also exit the underground space 800 through the opening 500. Note that this opening 500 can be provided with an openable / closable door, which is normally kept closed and is opened by remote control (or automatically) when the mobile stand 400 passes through the opening 500.

[0025] (Slope support) The mobile stand 400, on which seating is arranged in multiple tiers at an angle, moves up and down along the inclination of the seating. The slope support 410 shown in FIG. 3(b) guides the diagonal movement of the mobile stand 400 and also functions to support the mobile stand 400 as it moves up and down. In other words, the mobile stand 400 moves up and down while sliding on the slope support 410. Therefore, the slope support 410 is positioned so that it slopes approximately parallel (including parallel) to the inclination of the seating on the mobile stand 400. The slope support 410 can be supported by support columns 420 erected from the basement floor 600, and is installed at two or more locations (two locations in the figure) along the width of the mobile stand 400, as shown in FIG. 4.

[0026] Figure 5 is a step diagram showing the state in which the mobile stand 400 descends from the basement surface to the underground floor surface 600 of the underground space 800. The mobile stand 400 shown in Figure 5(a) is supported at a position where its lower end is at the height of the field 200 (i.e., the basement surface). At this time, it is advisable to provide a stopper mechanism or to tension the mobile stand 400 with a winch or the like to prevent it from descending.

[0027] When the mobile stand 400 is moved from the base surface to the underground floor surface 600, it is slid downward. The mobile stand 400 can be lowered using a winch or the like, or it can move by itself due to its self-propelled function. It can also be moved along the surface of an inclined support (e.g., a concrete structure) or by using rails or the like. As the mobile stand 400 descends, it passes through an opening 500 as shown in FIG. 5(b), and as it descends further, it slides along a sloped support 410 within the underground space 800 as shown in FIG. 6. Finally, the bottom of the mobile stand 400 touches the underground floor surface 600 as shown in FIG. 5(c).

[0028] On the other hand, when the mobile stand 400 is to be moved from the underground floor surface 600 to the basement surface, the mobile stand 400 is slid upward along the slope support 410. As the mobile stand 400 rises, it passes through the opening 500 and is eventually supported at a position where the bottom end of the mobile stand 400 is at the height of the field 200.

[0029] (earth embankment support) When constructing the multipurpose stadium 100 of the present invention, it is necessary to excavate the ground while installing retaining walls to form the underground space 800. This excavation generates a considerable amount of soil and sand, which must be removed from the site and landfilled at a soil disposal site to be disposed of as waste soil. This series of processes requires considerable costs and further reduces the amount of soil disposal land available, which is currently limited.

[0030] On the other hand, the fixed stand 300 and the mobile stand 400 placed at the height of the field 200 will be supported in an inclined position, necessitating the construction of a support structure for them. Therefore, as shown in Figure 7, it is advisable to construct an "earth embankment support 900" made of soil and sand, and use this earth embankment support 900 to support the fixed stand 300 and other components. In other words, the earth embankment support 900 is constructed using the excavated soil generated when forming the underground space 800. This allows the excavated soil to be used as material for the earth embankment support 900 rather than being disposed of as surplus soil. As a result, the costs of transporting soil and surplus soil disposal can be significantly reduced, and the limited amount of surplus soil disposal land is not reduced. [Industrial Applicability]

[0031] The multipurpose stadium of the present invention can be used for a variety of facilities, including stadiums for various sports such as soccer stadiums, baseball stadiums, and track and field stadiums, as well as entertainment facilities for various events such as concerts, exhibitions, and product fairs.
