As shown in FIG. 1, the building 10 according to the embodiment of the present invention is a stadium including a stadium 12 and a spectator seat 14 arranged so as to surround the stadium 12. The “stadium” is a place mainly for performing sports and the like, but the type of sports performed here is not particularly limited, and it is also possible to perform non-sports such as concerts and various events.

  The spectator seat 14 is formed by dividing the upper seat 20 and the lower seat 30 into two upper and lower stages. Each of the upper seat 20 and the lower seat 30 is a mortar-like structure that is inclined downward toward the stadium 12 (the portion on the stadium 12 side is formed lower in height than the portion on the opposite side). . A passage 40 is provided outside the lower seat 30, and the upper seat 20 is provided above the passage 40.

(Lower seat)
The lower seat 30 is configured by installing a seat (not shown) on a stepped floor 34 supported by an oblique beam 32. The diagonal beam 32 is configured to be inclined downward toward the stadium 12, and one end portion (the end portion on the stadium 12 side and the lower end portion) is joined to the base beam 16, and the other end portion ( The upper end portion on the side opposite to the stadium 12 is joined to the column 18B. Further, the central portion of the diagonal beam 32 is joined to a column 18A disposed on the stadium 12 side with respect to the column 18B. The corrugated floor 34 is a step-like floor slab spanned between diagonal beams 32 adjacent to each other in the longitudinal direction (front and back directions) in FIG. 1, and a seat is installed on each step. .

(aisle)
The passage 40 is a space formed on the floor board 40FL supported by the lower beam 42 spanned between the pillar 18B and the pillar 18C outside the pillar 18 (opposite the stadium 12). . The surface (walking surface) of the floor board 40FL is formed at a height position equal to the upper end surface of the lower seat 30, and the user of the building 10 can pass between the passage 40 and the lower seat 30 without going through a stairs or the like. Can move.

  Above the passage 40, an upper beam 44 is disposed between the columns 18B and 18C. Similar to the lower beam 42, a floor plate is installed on the upper beam 44, and a passage 46 is formed above.

  The passages 40 and 46 are concourses that allow users of the building 10, which is a stadium, to pass therethrough, but are not necessarily spaces provided only for passage. For example, it can be used for any application such as a store, a resting place, a spectator seat, a broadcast seat.

(Upper seat)
Similar to the lower seat 30, the upper seat 20 is configured by installing a seat (not shown) on a stepped floor 24 supported by the diagonal beam 22. The diagonal beam 22 in the upper seat 20 is provided above the upper beam 44 of the passage 40 and is inclined downward toward the playing field 12. Further, the diagonal beam 22 is joined to the upper ends of the pillars 18B and 18C, and the jumping part 22B jumps to the playing field 12 side (that is, above the lower seat 30) from the pillar 18B, and the outer side from the pillar 18C. And a jumping portion 22C that jumps out. The corrugated floor 24 is a step-like floor slab spanned between diagonal beams 22 adjacent to each other in the front-rear direction (front and back directions) in FIG. 1, and a seat is installed on each step. .

  Similarly, the stepped floor 24 in the upper seat 20 is also formed with a jumping portion 24B that jumps to the playing field 12 side from the column 18B and a jumping portion 24C that jumps outward from the column 18C. In the following description, the jumping portions 22B and 24B may be collectively referred to as the jumping portion 20B, and the jumping portions 22C and 24C may be collectively referred to as the jumping portion 20C.

  The lower surface 20BE of the protruding portion 20B of the upper seat 20, that is, the lower surface 22BE of the horizontal portion formed at the tip of the protruding portion 22B of the oblique beam 22 is formed at a position lower than the lower surface 44E of the upper beam 44 of the passage 40. Yes.

  In other words, the height H1 from the surface of the floor plate 40FL to the lower surface 22BE of the protruding portion 20B (the lower surface 20BE of the protruding portion 20B) is lower than the height H2 from the surface of the floor plate 40FL to the lower surface 44E of the upper beam 44. .

  As shown in FIG. 2, when the user of the building 10 looks at the stadium 12 in a standing posture in the passage 40, the height H1 is opposite to the end of the stadium 12 (opposite the audience seat 14 where the user is present). The height of the lower seat 30 in the spectator seat 14 is set to a height at which the user can visually recognize the seat.

(Outdoor stairs)
An outer wall 19 is constructed between the pillars 18 </ b> C arranged outside the passage 40. An outdoor staircase 50 is provided outside the outer wall 19, that is, outside the passage 40. The outdoor staircase 50 is a vertical moving means for the user of the building 10 to move between the external site S, the passage 40 and the passage 46. Further, the user can move between the passage 46 and the upper seat 20 through the stairs 52. Thus, the user can move from the lower seat 30 to the upper seat 20 through the passage 40, the outdoor staircase 50, the passage 46 and the staircase 52.

(Action / Effect)
In FIG. 3, the upper seat 20 in the building 10 according to the present embodiment is indicated by a solid line, and the upper seats 200 and 220 according to the first and second comparative examples are indicated by a broken line. The upper seats 20, 200, and 220 have the same number of seats, that is, spectator capacity, and the horizontal distances L between the ends on the stadium 12 side and the outer ends of the upper seats 20, 200, and 220 are all equal. .

  The upper seat 200 according to the first comparative example does not jump above the lower seat 30. The distance between the outer end portions of the upper seat 200 and the upper seat 200 in the spectator seat 14 facing each other across the stadium 12 is S2.

  On the other hand, the upper seat 20 according to the present embodiment includes a jumping portion 20B that jumps above the lower seat 30, and the upper seat 20 and the lower seat 30 overlap in plan view. That is, the upper seat 20 is arranged closer to the stadium 12 than the upper seat 200 of the first comparative example. For this reason, the distance S1 between the outer end portions of the upper seat 20 is smaller than S2.

  Therefore, in the building 10 according to the present embodiment, compared to the first comparative example in which the upper seat 200 and the lower seat 30 do not overlap in plan view, the building area (the audience seat formed by the lower seat 30 and the upper seat 20) 14 horizontal projection areas) can be reduced.

  The upper seat 220 according to the second comparative example includes a jumping portion 220 </ b> B that jumps above the lower seat 30. The height H3 from the surface of the floor plate 40FL to the lower surface 220BE of the protruding portion 220B in the passage 40 is formed to be equal to the height H2 from the surface of the floor plate 40FL to the lower surface 44E of the upper beam 44. The height of the outer end portion of the upper seat 220 (height from the ground surface GL) is T3.

  In contrast, the height H1 of the lower surface 20BE of the protruding portion 20B in the upper seat 20 according to the present embodiment (the height from the surface of the floor plate 40FL in the passage 40) H1 is lower than the lower surface 44E of the upper beam 44 from the surface of the floor plate 40FL. It is lower than the height H2. That is, the upper seat 20 is arranged at a lower position than the upper seat 220 of the second comparative example. For this reason, the height (height from the ground surface GL) T1 of the outer end portion of the upper seat 20 is smaller than T3.

  Therefore, in the building 10 according to the present embodiment, the building height can be reduced as compared with the second comparative example in which the upper seat 220 is arranged at a high position.

  Further, in the building 10 according to the present embodiment, the moving means for moving between the lower seat 30 and the upper seat 20 is the outdoor staircase 50 disposed outside the passage 40 and the outer wall 19. For this reason, the line of sight from the passage 40 to the stadium 12 is not easily obstructed. Accordingly, a spectator seat or a live seat can be provided in the passage 40.

  In addition, a staircase is installed indoors as compared with a case where a moving means for moving between the lower seat 30 and the upper seat 20 is provided indoors (portion close to the stadium 12 when viewed from the outer wall 19). Therefore, the indoor space can be reduced. Thereby, the scale of the building can be reduced.

  In the present embodiment, the moving means for moving between the lower seat 30 and the upper seat 20 is the outdoor staircase 50 disposed outside the outer wall 19, but the embodiment of the present invention is based on this. Not exclusively. For example, like the indoor staircase 54 shown in FIG. In this way, the user of the building 10 is unlikely to be exposed to wind and rain when moving between the lower seat 30 and the upper seat 20. Moreover, since the indoor staircase 54 is disposed outside the passage 40, the line of sight from the passage 40 to the stadium 12 is not easily obstructed.

  In the present embodiment, the outer wall 19 is formed between the pillars 18C at the outer end of the passage 40. However, the embodiment of the present invention is not limited to this, and the outer wall 19 is not formed. May be formed. Alternatively, a portion where the outer wall 19 is formed and a portion where the outer wall 19 is not formed may be mixed. In this way, the structure of the building 10 can be made light.

  Moreover, in this embodiment, the spectator seat 14 provided with the upper seat 20 and the lower seat 30 is arrange | positioned so that the circumference | surroundings of the stadium 12 may be surrounded, However, Embodiment of this invention is not restricted to this. For example, the spectator seats 14 may be arranged along one side of the stadium 12 or may be arranged so as to sandwich the stadium 12 from both sides. Similarly, the building 10 is not limited to a stadium, and can be any building with a spectator seat, such as an outdoor sports field, a racetrack, an outdoor theater, a gymnasium, and a dome. As described above, the present invention can be implemented in various modes.
