DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a structure such as an athletic stadium having a retractable dome roof.

(Prior Art) Conventionally, a dome roof of a building structure in an athletic stadium or the like is divided in a radial direction into almost the same width, and is composed of a plurality of movable roofs that are bent in a spherical shape having the same spherical center and different curvature radii An openable dome roof that movably supports both ends of each movable roof on a guide member erected on the outer peripheral edge of the movable roof and separates the movable roofs from each other and closes the roof to open and close the roof.
It is proposed in Japanese Patent No. 274029.

(Problems to be Solved by the Invention) In the conventional retractable dome roof, since the roof surface is formed in a spherical shape with the same spherical center, when applied to, for example, a baseball field, the one end side in the radial direction is Since the height of the home base on the side where the roof is located is low, the home base must be installed closer to the center side, and the space on the side of the outfield seat located on the other end side in the radial direction becomes narrower. become.

In addition, when used for multiple purposes, when a stage is provided on the center side, the generated sounds overlap each other, which adversely affects the acoustic effect.

The present invention has been proposed in view of the above problems of the prior art, and the object of the present invention is to use the space more effectively, improve the acoustic environment, and further reduce the amount of material to be opened and closed. The point is to provide an all-weather structure with a dome roof.

(Means for Solving the Problems) In order to achieve the above-mentioned object, a structure having a retractable dome roof according to the present invention is a dome roof arranged between outer walls of a building structure such as an athletic stadium. While making the plane shape of the ellipse an elliptical shape, the longitudinal cross-sectional shape of the roof surface in the major axis direction of the same ellipse is an egg shape, and the vertical cross-sectional shape of the roof surface of the same elliptical minor axis direction is an arc shape, and The dome roof is divided substantially equally over the major axis direction of the ellipse to form a plurality of independent movable split roof pieces each having a substantially arcuate vertical cross-section in the minor axis direction. Both ends of the roof piece are movably mounted on guide rails laid in the elliptical major axis direction of the structure.

According to the invention of claim 2, the height to the roof surface on one end side of each movable split roof piece in the longitudinal cross section of the elliptical shape is made higher than the height to the roof surface on the other end side. Is.

(Operation) Since the present invention is configured as described above, the minor axis direction extending in the minor axis direction of the elliptical plane is substantially evenly divided in the major axis direction of the elliptical plane dome roof. The roof surface is opened and closed by separating and moving a plurality of independent movable split roof pieces each having a substantially arcuate vertical cross-sectional shape from the center of the elliptical shape in the major axis direction to both end sides.

Thus, since the vertical cross-sectional shape of the dome roof in the major axis direction in the elliptical shape is an egg shape, when applied to a baseball stadium, the home base is placed close to one end side in the major axis direction of the elliptical shape. By locating it in the open position, the space on the side of the outfield seat can be increased. When a stage is provided on the center side, the sound is dispersed and the acoustic environment is improved.

According to the invention of claim 2, the height to the roof surface on the one end side of each movable split roof strip in the longitudinal cross section of the elliptical shape is made higher than the height to the roof surface on the other end side. As a result, when applied to a baseball field, a space is provided on the side of the outfield seats.

(Example) Hereinafter, an illustrated example in which the present invention is applied to an all-weather baseball field having a dome roof opening / closing device will be described.

The dome roof surface has an oval shape in plan view as shown in (A1) of FIG. 5, and a longitudinal cross-sectional shape in the major axis direction of the oval shape as egg-shaped as shown in (A2) of FIG. The upper part of the second base (S) has a maximum height h max so that the hit ball does not collide with the roof surface, and is a curved shape that covers the hit ball trajectory. Further, the vertical cross-sectional shape of the ellipse in the minor axis direction is formed in a substantially arc shape.

Thus, the curved roof is substantially equally divided along the major axis direction of the ellipse, and the longitudinal cross-sectional shape of the elliptical minor axis extending in the minor axis direction of the ellipse is substantially arcuate. A guide rail which is composed of a plurality of movable split roof pieces (1), and both ends of each of the movable split roof pieces (1) on the minor axis side of the ellipse are laid in the elliptical major axis direction on the outer wall (2). (3) is movably supported on the movable split roof piece (1) so that the movable split roof piece (1) can be moved to the left and right ends from the center of the elliptical shape in the major axis direction, and the movable split roof pieces (1) are separated from each other;
The roof surface is opened and closed by bringing them close to each other.

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.

Thus, of the movable split roof pieces (1), the movable split roof piece (1) on the home base side has a higher height to the roof surface, and the movable split roof piece (1) on the center side is the roof surface. The space inside the dome is formed with a low height.

Since the illustrated embodiment is configured as described above,
When the dome roof has the same spherical center and different radii of curvature, the conventional structure has the same maximum height, and the dome roof surface of the conventional structure has a planar shape as shown in FIG. As shown in (A′1) of FIG. 4, the elliptical longitudinal major surface becomes a curved surface with the maximum height moved to the center side, as shown in (A′2) of FIG. F ') is narrower than the outfield seat (F) in the present embodiment, and thus becomes a space.

In the figure, (H ') and (S') are the second base as well as the home base in the conventional structure.

Further, when the same ground use method as that of this embodiment is adopted in the conventional structure, the plane shape thereof is the same as that of (A'1) in (B1) of FIG. 5, but its longitudinal cross-sectional shape is shown in FIG. (B2) and the maximum height h'max increases.

According to the embodiment, by making the plane shape an elliptical shape, while taking the same required volume as the conventional structure,
The roof support frame extends in the minor axis direction, and the roof surface can be constructed with a minimum amount of materials.

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. In many cases, the acoustic environment is impaired, but in the above-described embodiment, the egg-shaped vertical cross section of the roof surface can disperse the sound, and the acoustic environment can be significantly improved.

Further, as is clear from FIG. 4, according to the above-mentioned embodiment, the internal volume can be reduced, so that the running cost for air conditioning can be saved.

Further, according to the above-mentioned embodiment, the dome roof having the front surface and the back surface on the left and right sides of the elliptical major axis of the dome, and the different curved surfaces on the same surface are expressed by the roof curved surface, and the dome roof having an excellent design effect is obtained. A building that has is constructed.

(Effects of the Invention) According to the present invention, as described above, the planar shape of the dome roof of a building structure such as an athletic stadium is elliptical, and the longitudinal cross-sectional shape of the ellipse in the major axis direction is egg-shaped. The vertical cross-section of the same ellipse in the minor axis direction is substantially arcuate, and the dome roof formed in this manner is divided into approximately equal parts along the major axis direction of the ellipse, and A plurality of independent movable split roof pieces each having a substantially arcuate vertical cross section are formed, and the movable split roof pieces are movably mounted on the guide rails laid in the elliptical major axis direction of the structure, and the movable split roof is provided. Since the piece can be moved to the left and right ends from the center of the elliptical major axis direction, the movable split roof pieces are separated from each other,
The close proximity opens and closes the dome roof so that the building structure can be used as an all-weather sports arena.

As described above, by making the longitudinal cross-sectional shape of the dome roof egg-shaped, the highest height is located at one end side in the major axis direction of the ellipse, and when applied to a baseball field, on the outfield seat side. A wide space with a margin can be taken, the internal volume can be reduced, and the running cost for air conditioning can be reduced. Furthermore, when a stage is provided on the center side for holding a concert, the sound can be dispersed, and a great effect can be obtained in improving the sound.

Further, since the dome roof has an elliptical planar shape, the supporting frame of each movable split roof piece is installed so as to extend toward the minor axis side of the elliptical shape, which saves the amount of material and is economical. It is possible to have a different frame.

In the invention of claim 2, the height to the roof surface on one end side of each movable split roof piece in the elliptical longitudinal cross section is made higher than the height to the roof surface on the other end side. When it is applied to a baseball field, it has a spacious space on the side of the outfield seats.
