が、特開昭61−274029号公報において提案されている。In addition, the dome roof is composed of a plurality of movable roof materials which are divided into substantially the same width in the radial direction and are bent into a spherical shape having the same spherical center and different curvature radii, and both ends of each movable roof material are mounted on the outer peripheral edge. Japanese Patent Application Laid-Open No. 61-274029 proposes a device which is movably supported by a bridged guide member.
（発明が解決しようとする課題） しかしながら前者はドーム屋根の一部を開閉するだけ
で、屋根構造部材等によって自然環境が損なわれ、快適
な運動競技場を提供することができない。(Problems to be Solved by the Invention) However, the former merely opens and closes a part of the dome roof, and the natural environment is impaired by the roof structural members and the like, and a comfortable athletic stadium cannot be provided.

に載架して構成されている。(Means for Solving the Problems) In order to achieve the above-mentioned object, a retractable dome roof according to the present invention has a planar shape of a dome roof arranged between outer walls of a building structure such as an athletic stadium. With a rectangular shape, and the vertical cross-sectional shape of the rectangular flat roof in the long side direction is egg-shaped, and the vertical cross-sectional shape of the rectangular flat roof in the short side direction is a hollow arc shape, and the dome roof is a rectangular flat surface. The roof is divided into approximately equal parts along the long side direction to form a plurality of independent movable split roof pieces, each of which has a substantially rectangular arc-shaped longitudinal section in the short side direction. Both end legs of one piece are movably mounted on a rail member that is installed over the long side direction of the rectangular flat roof of the structure.

めることによって屋根面を開閉するものである。(Operation) Since the present invention is configured as described above, the vertical cross-sectional shape in the short side direction of the roof of the rectangular plane is substantially evenly divided in the long side direction of the rectangular plane in the dome roof of the rectangular plane. Open and close the roof surface by separating and moving a plurality of independent movable split roof pieces each having an arc shape from the center of the rectangular flat roof in the long-side direction along the rail member to both end sides. It is a thing.
而して前記ドーム屋根の前記長方形平面の屋根におけ

で、センター側にステージを設けて使用した場合、音が
分散され、音響環境が改善される。Thus, the longitudinal cross-sectional shape in the long side direction of the rectangular flat roof of the dome roof is formed in an egg shape, so when the stage is provided on the center side, the sound is dispersed and the acoustic environment is Be improved.
（実施例） 以下本発明を全天候型の野球場におけるドーム屋根開
閉装置に適用した図示の実施例について説明する。(Example) Hereinafter, an illustrated example in which the present invention is applied to a dome roof opening / closing device in an all-weather baseball stadium will be described.

（Ｓ）上部が最高高さとなり、且つ打球軌跡をカバーし
た曲線形とされている。また前記長方形平面の屋根にお
ける短辺方向の縦断面形状は円弧状に形成されている。The dome roof surface has a rectangular planar shape, and the longitudinal cross-sectional shape in the long side direction of the rectangular flat roof is egg-shaped, and the upper part of the second base (S) has the highest height so that the hit ball does not collide with the roof surface. , And has a curved shape that covers the trajectory of the hit ball. Further, the vertical cross-section of the rectangular flat roof in the direction of the short side is formed in an arc shape.

しめることによって屋根面を開閉するものである。Thus, the curved roof is substantially equally divided along the long side direction of the rectangular flat roof, and a plurality of independent vertical cross-sectional shapes extending in the short side direction of the rectangular flat roof are movable in an arc shape. The movable roof shingles (1) are divided into two pieces, and the short side both ends of the rectangular flat roof of each movable split roof piece (1) are arranged on the outer wall (2) in the long side direction of the rectangular flat roof. Movably mounted on a rail member (3) extending to the left and right of the movable split roof piece (1) from the center in the long side direction of the roof of the rectangular plane to the left and right ends, and the movable split roof pieces (1) are movable. The roof surface is opened and closed by separating the roof pieces (1) from each other or by bringing them closer to each other.
図中（１′）は長辺方向両端部に配設された固定屋根
である。In the figure, (1 ') is a fixed roof arranged at both ends in the long side direction.
なお相隣る可動分割屋根片（１）の重合部分の隙間
は、採光、換気部分として利用される。The space between the overlapping portions of the movable split roof pieces (1) adjacent to each other is used as a daylighting and ventilation portion.

くし、センター側の可動分割屋根片（１）は屋根面まで
の高さを低くしたドーム内空間を形成し、外野席側のス
ペースが広くとれるように構成されている。Thus, among the movable split roof pieces (1), the height of the movable split roof pieces (1) on the home base side to the roof surface is increased, and the movable split roof pieces (1) on the center side are roof surfaces. The interior space of the dome is formed with a low height to allow a large space on the side of the outfield seats.
図中（４）はスタンド、（５）はグランド、（６）は
可動分割屋根片（１）の走行装置である。In the figure, (4) is a stand, (5) is a ground, and (6) is a traveling device of the movable split roof piece (1).

球面状に形成された円形平面の前記従来構造と同じ敷地
面積で観覧席を多くとれ、特に運動競技場はトラック、
各種コート形状が長方形であるので、一層有利である。According to the above-mentioned embodiment, by making the planar shape of the roof rectangular, it is possible to obtain a large number of seats in the same site area as the conventional structure of the circular flat surface in which the dome roof is formed into a spherical shape having the same spherical center and different radii of curvature. , Especially athletic stadiums,
It is even more advantageous because the various coat shapes are rectangular.

ができ、音響環境が大幅に改善される。Further, when the baseball field is used for multiple purposes, for example, when a stage is provided on the center side for a concert, and the generated sound is formed on the concentric curved dome roof as in the conventional structure, the sound overlapping rate is large. However, since the longitudinal cross-sectional shape of the roof surface along the long-side direction of the rectangular planar roof is egg-shaped in the above embodiment, the sound can be dispersed. , The acoustic environment is greatly improved.

く、走行装置が簡略化される。Further, each of the movable split roof pieces (1) is an arc-shaped roof having substantially the same diameter and extending in the short side direction of the rectangular flat roof divided into the same width over the long side direction of the rectangular flat roof. Therefore, the rail member (3) only needs to be laid one or two on the legs of each movable split roof piece (1), and the traveling device is simplified.
（発明の効果） 本発明によればドーム屋根の平面形状が長方形とされ

面積で観覧席が多くとれ、特に運動競技場は、トラック
各種コートが長方形であるのでより、一層有利である。(Effect of the Invention) According to the present invention, since the dome roof has a rectangular planar shape, a large number of seats can be taken in the same site area as compared with the conventional structure having a circular flat surface. It is even more advantageous because the coat is rectangular.

でよく、走行装置も簡略化される。Further, each of the movable split roof pieces is formed into a plurality of independent movable split roof pieces each having an arcuate vertical cross-sectional shape in the short side direction, which is substantially evenly divided over the long side direction of the rectangular flat roof. Since both end legs of the movable split roof piece are movably mounted on a rail member installed over the long side direction of the rectangular flat roof in the structure, the dome roof is almost fully opened, The truss legs of the movable split roof frame have a rectangular shape, and the rail member laid on the outer wall may be one or two for each movable split roof strip, and the traveling device is also simplified.
更にまたドーム屋根の前記長方形平面の屋根の長辺方
