Usually, the arena is configured integrally with a main frame that supports the entire arena and a stand frame that is a framework of stand seats.
In this regard, in the case where the main frame and the stand frame are integrally configured, the main frame bears loads such as the weight of the stand frame and seismic force applied to the main frame. I needed to. However, if the cross-sectional size is increased, the cost of members is increased, and the work of transporting and installing the large-sized main frame is heavy. On the other hand, when the main frame and the stand frame are separated from each other, the respective installation locations are required, so that the indoor space may be narrowed as compared with the case where they are integrally configured.

  Therefore, the present invention separates the main frame and the stand frame to prevent the load from being concentrated on a specific member, and thereby eliminates the need to increase the cross-sectional size of the member, thereby reducing the member cost. It is another object of the present invention to provide an arena in which the indoor space is not narrowed while the main frame and the stand frame are separated.

The main frame 4 is a so-called H-shaped steel, and is composed of a pair of upright portions 42 erected in the vertical direction and an erection portion 41 erected at the upper ends of the pair of erected portions 42.

The lower ends of the pair of standing portions 42 are joined to the foundation 54 near the wall W.
The erection portion 41 has a central portion protruding upward, and the roof plate R supported upward is inclined from the center to both ends in the width direction.

  The main frame 4 having such a configuration is continuously arranged at regular intervals along the longitudinal direction of the arena 1. The plurality of main frames 4 arranged at regular intervals are connected by beams 43 extending in the longitudinal direction of the arena 1. As described above, the arena 1 basically has a structure in which a plurality of main frames 4 having the same shape are sequentially arranged in the longitudinal direction, and the length of the main frames 4 and the number of the main frames 4 to be continuously arranged are determined. Determines the size of the arena 1.

● Stand frame 31
The stand frame 31 shown in FIGS. 2 and 3 is a member constituting the stand seat 3, supports the customer seat 33, and is provided so as to surround the substantially rectangular field portion 2. .
The stand frame 31 has a lower end joined to the foundations 51, 52, 53, and stands on the foundations 51, 52, 53, and is fixedly installed. Further, it is provided independently of the main frame 4 and the wall W.
In the following description, when referring to the direction of the stand frame 31, the direction that is perpendicular to the wall portion W and connects the field portion 2 and the wall portion W is the direction between beams, and is orthogonal to the direction between beams. A direction parallel to the wall W or a direction in which the plurality of main frames 4 are provided may be referred to as a row direction.

  The stand frame 31 includes three types of substantially bar-shaped standing portions 311, 312, 313 having different heights, and bridging portions 314, 315 bridging the upper ends of the rising portions 311, 312, 313 in the beam-to-beam direction, and extending in the row direction. It is composed of beams 316, 317, 318.

The standing portions 311, 312, and 313 are joined to the foundations 51, 52, and 53, respectively, and stand vertically or substantially vertically.
The standing portion 311 stands vertically upward from the foundation 51 at a position closest to the field portion 2 and is connected to the beam 316 at the upper end.
The erected portion 312 is erected vertically upward from the foundation 52 near substantially the middle between the erected portion 311 and the erected portion 313, and is connected to the beam 317 at the upper end.
The erected portion 313 is erected diagonally upward from the foundation 53 toward the field portion 2 near the wall portion W farthest from the field portion 2 and connected to the beam 318 at the upper end.
These standing portions 311, 312, and 313 have different heights, and are arranged in ascending order of height from the field portion 2 toward the wall portion W. As a result, from the field portion 2 toward the wall portion W, The stand seat 3 can be provided stepwise.

Further, extending portions 314 and 315 extending in the direction between beams are provided between the standing portions 311 and 312 and between the standing portions 312 and 313, respectively.
Further, the upright portions 311, 312, 313 are provided continuously at regular intervals along the row direction. Each of the upright portions 311, 312, and 313 provided at regular intervals in the row direction has beams 316, 317, and 318 extending in the row direction at the upper end thereof. , 317, 318 connect the standing portions 311, 312, 313 arranged in the column direction.
The erection portions 314 and 315 and the beams 316, 317 and 318 support the passenger seat 33 together with the erection portions 311, 312 and 313.

  In addition, since the seat 33 is located at a position sufficiently higher than the floor slab 5 due to the standing portions 311, 312, and 313 of the stand frame 31, additional space such as a toilet, an office, an air conditioner, etc. Can be provided.

Here, the positional relationship between the standing portion 42 of the main frame 4 and the stand frame 31 will be described with reference to FIG.
In the longitudinal direction of the arena 1, the standing portions 42 of the main frame 4 are arranged at regular intervals along the wall W of the arena 1. Similarly, the standing portions 313 of the stand frame 31 are arranged at regular intervals along the wall portion W of the arena 1. As a result, the upright portions 42 and the upright portions 313 are alternately joined to the foundations 54 and 53 in the girder direction, and the joints are arranged in a line in the girder direction.

  On the other hand, the standing portion 313 of the stand frame 31 is joined to the foundation 53 between the standing portions 42 of the adjacent main frames 4. In this regard, if the standing portion 313 of the stand frame 31 extends straight upward in the vertical direction, the standing portion 42 of the main frame 4 may interfere with the beam 318 of the stand frame 31 and the customer seat 33 constituting the stand seat 3. become. However, the standing portion 313 of the stand frame 31 extends diagonally upward from the foundation 53 toward the field portion 2 side, and the upper end of the standing portion 313 of the stand frame 31 is horizontally It is located closer to the field section 2 than the setting section 42. As a result, the beam 318 provided at the upper end of the standing portion 313 of the stand frame 31 and the standing portion 42 of the main seat 4 do not interfere with each other.

According to the arena 1 according to the above-described embodiment, the main frame 4 and the stand frame 31 are separated from each other and have independent structures. It is possible to prevent the concentration of the load on the device. As a result, since a large load is not applied to a specific member such as the upright portion 42 of the main frame 4, there is no need to increase the cross-sectional size of the upright portion 42, leading to a reduction in member costs.
In addition, between the portions where the adjacent standing portions 42 are joined to the foundation 54, the standing portions 313 of the stand frame 31 are joined to the foundation 53, so that the space between the standing portions 42 and the standing portions 313 is increased. They are erected on the foundations 54 and 53 without waste, and the indoor space of the arena 1 is not narrowed.

  In the arena 1 according to the present embodiment, the stand frame 31 is erected on the foundations 51, 52, and 53 by pillars configured as three types of erected portions 311, 312, and 313. Not limited to this, two or four or more types of plural members may be provided as long as the members constituting the columns of the stand frame 31 on the wall W side are erected diagonally upward from the foundation 53 toward the field portion 2. The support may constitute the stand frame 31.

  In addition, the arena 1 according to the present embodiment can be extended by providing the main frame 4 and the stand frame 31 after the existing arena, if necessary. Conversely, if necessary, the main frame 4 and the stand frame 31 can be removed after the existing installation to reduce the number of buildings.

  According to the present invention, the number of members can be reduced, so that an arena can be constructed even by a business entity with relatively little funding. The present invention can also be used in a theme park for a limited time and an arena as an Olympic facility, which is constructed on the assumption that it will be demolished several years later.
