Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a retractable dome roof used in leisure facilities, multipurpose halls such as event venues, stadiums, and the like.

[Conventional technology]

Conventionally, all-weather domes have been used as facilities for baseball stadiums and stadiums, covering the entire facility with a spherical or arched roof, and are primarily intended to deal with rain, snowfall, wind, etc. It is.

In response, there is an increasing demand for retractable dome roofs that bring in as much natural light and fresh air as possible when the weather is nice and give a sense of openness. Regarding this type of retractable dome roof,
Conventionally, various types have been developed.

For example, JP-A-59-126835 discloses a hollow hemispherical dome in which a diametrically band-shaped opening is formed at the top of the dome body, and a lid body that can be opened and closed is provided in the opening. has been done.

In addition, Japanese Patent Application Laid-open No. 61-274029 discloses that the dome roof is divided into radial directions with approximately the same width, and consists of a plurality of arch-shaped movable roofs with different radii of curvature, and each movable roof is slid along parallel tracks. A freely movable structure is disclosed.

Also, Nikkei Architecture August 21, 1989 issue (
Nikkei BP, Inc.) pages 108 to 119, there are two top roofs that can be moved in parallel along parallel tracks, a fixed roof on the - side, and a rotating roof on the other side that can be rotated and moved along a circular track.
A retractable dome roof called a skydome is described, which consists of two roof elements.

[Problem to be solved by the invention]

As mentioned above, various types of retractable dome roofs have been developed, but the conventional retractable dome roofs have the following problems.

First of all, in the case where the opening is provided at the top of the dome roof, apart from improving ventilation, it is not possible to adequately meet the demand for letting in direct sunlight due to the angle of sunlight.

In addition, with a free-standing roof in which the movable roof section runs along parallel tracks, it requires space for roof storage, and since it can only be opened and closed in one direction, there are various factors such as the purpose of use, time of day, weather, etc. When selecting an aperture shape according to the above, there are few variations in the aperture shape, and the range of selection is narrow.

In addition, in the case of the sky dome described above, although it has the advantage of being able to obtain a relatively large opening area, the storage direction of the two top roots and the fixed roof on one side cannot be changed, so there is still little variation in the opening shape. , the range of choices is narrow when you want to change the opening position depending on the direction of sunlight, wind direction, and purpose of use.

The present invention aims to solve the above-mentioned problems in the prior art.

[Means to solve the problem]

The retractable dome roof of the present invention has a dome roof surface divided into a plurality of roof elements including an arch-shaped top root, and at least the top root can be translated and horizontally rotated along a parallel trajectory and a circular trajectory. It is.

Parallel tracks are installed at intervals corresponding to the distance between the lower ends of the arch of the crown root, while circular tracks are also installed with a diameter corresponding to the distance between the lower ends. Moreover, a running trajectory switching means for switching between parallel movement and horizontal rotational movement of the top root is provided between the parallel track and the circular track.

Parallel tracks do not necessarily have to be provided in one direction, but can also be provided in multiple directions.

The running track switching means may be, for example, a point-type device used in railways, and the top root can be switched by operating a bogie installed at the lower end of the top root along a parallel track and a circular track and switching the track at the point position. It can be translated or rotated. In addition, it is also possible to change the traveling trajectory of the top root by switching the bogie between a bogie dedicated to parallel tracks and a bogie dedicated to circular track. Furthermore, the means for moving the top root is not limited to the trolley type, but may also be a rack and pinion type, a cable or the like.

In the present invention, there are no particular limitations on the shape or other aspects of the roof elements other than the top root, but in order to obtain a large opening ratio and increase the variety of opening shapes,
It is desirable that part or all of it can be moved separately from the top root.

〔Example〕

Next, the illustrated embodiment will be described.

FIG. 1 shows fifteen embodiments in which the retractable dome roof of the present invention is used in stadiums, event venues, etc.

The dome in this embodiment has a spherical dome roof 1 built on top of a cylindrical dome side wall 7 made of reinforced concrete or steel reinforced concrete. The roof surface is divided into three roof elements, consisting of a T-shaped roof root 2 covering the top of the dome roof 1, an inner side roof 5 and an outer side roof 6. As each of these three-divided roof elements, for example, a membrane material such as a translucent Teflon membrane can be used on the top surface of a framework consisting of a three-dimensional truss, but the membrane material is not limited to metal. Roof structures other than those using boards or other panels or membrane structures may also be used.
For relatively small-scale dome roofs, concrete roofing materials are also possible.

The top root 2 has parallel tracks 3a provided in two directions perpendicular to each other.
, 3b, and rotationally movable along a circular orbit 4 located above the dome side wall 7. In addition, in FIG. 1, 8 is a track support frame for supporting the load of the parallel tracks 3a, 3b and the top root 2 sliding along these.

2 to 5 show how the top root 2 moves along the parallel tracks 3a, 3b and the circular track 4.

Figure 2 shows the sliding movement along a pair of parallel tracks 3a.
The top root 2 moves in the vertical direction in the figure. FIG. 3 shows the state of sliding along the circular orbit 4, and horizontal rotational movement from the position shown in FIG. 2 to the position shown in FIG. 4, which will be described later, can be performed. Note that although the arrow in the figure is for clockwise rotation, it is of course also possible to rotate counterclockwise. FIG. 4 shows the state of sliding along the parallel track 3b, and the top root 2 moves in the left-right direction in the figure. FIG. 5 shows the state of sliding along the circular orbit 4, which is a horizontal rotation from the position shown in FIG. 4 to the position shown in FIG. however,
In this case, the front and back of the top root 2 will be reversed to that shown in FIG.

The inner side roof 5 and the outer side roof 6 in the embodiment shown in FIG. 1 have a shape similar to that of a spherical surface divided in half,
It is structurally stable by supporting the arcuate lower end. These inner side roof 5 and outer side roof 6 are also rotatable along separate circular orbits, and although not shown, the circular orbit of the outer side roof 6 is inside the circular orbit 4 of the top root 2. A circular track of the inner side roof 5 is provided inside the inner side. In addition, the inner side roof 5 is rotated horizontally,
It can be stored inside the side outer roof 6.

As the driving means, bogies and other various traveling devices used in conventional retractable dome roofs can be used.

6 to 13 show some of the various opening shapes in the embodiment of FIG. 1 described above.

Figures 6 and 7 are based on the assumption that the stadium will be used as a baseball field, etc. In Figure 6, the top roof 2, inner side roof 5, and outer side roof 6 are all moved toward the infield seats, and the opening is This is the case when the ratio is increased. Depending on the direction of sunlight, wind direction, etc., it can be placed closer to the outfield seats, left field seats, right field seats, etc. In FIG. 7, the top root 2 is moved toward the infield seats, and the inner side roof 5 and the outer side roof 6 diagonally intersect with each other, thereby leaving only the outfield side open.

Figures 8 to 10 are mainly intended for use in track and field events, soccer, football, etc.
In the figure, the top root 2 is moved to the lower side in the figure, and the inner side roof 5 and the outer side roof 6 are moved left and right to give an opening shape that is close to a rectangle. FIG. 9 corresponds to a state in which the inner side roof 5 is rotated to the inside of the outer side roof 6 from the state shown in FIG. Moreover, FIG. 10 corresponds to a state in which the top root 2 is horizontally rotated at the center and then stacked on the side outer roof 6.

Figures 11 to 13 are mainly intended to be used for events, etc. In Figure 11, all roof elements including the roof root 2 are moved to the upper side of the figure to increase the opening ratio. ing. In Fig. 12, the top root 2, the inner side roof 5, and the outer side roof 6 intersect at right angles.
When setting up a stage under the top root 2 located in the center,
Lighting and sound-related equipment can be hung from the top root 2. 13th rg:J corresponds to a state where each roof element is rotated by 90 degrees from the state shown in FIG.

In the embodiment described above, the dome roof surface is divided into three parts, but the number of divisions, the shape of the divisions, etc. are arbitrary. Further, part or all of the divided roof elements may be fixed roof elements.

〔Effect of the invention〕

■ The arched top root is stable in shape and can stand on its own.

■ By switching points, etc., the top root can be moved in parallel or rotated, and there are many variations in the opening shape.

Therefore, the purpose of use (e.g. baseball, stage, track,
An appropriate opening shape can be selected depending on the time, weather, etc. (football, etc.).

■ If parallel tracks are provided in multiple directions, variations in opening shapes can be further increased.

■ Separate tracks are provided for roof elements other than the roof root, allowing them to slide, increasing the variety of opening shapes.

■ Since the top root is supported at its lower end and the lower end slides, installation of the traveling device during construction and maintenance after construction are easy.
