Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a stack in which a plurality of fan-shaped roof elements are rotationally moved in the circumferential direction of the roof to open and close the entire roof. The present invention relates to a rotary movable opening / closing structure.

[Conventional technology]

In recent years, openable roofs have been put up on stadiums and stadiums.

Various types of roofs are planned worldwide as this type of roof, and a typical example thereof is a stacking and rotating type roof (Japanese Patent Laid-Open No. 63-280136, Japanese Patent Laid-Open No. 64-39).
(See Japanese Patent No. 479).

The openable roof according to this method is constructed by dividing the roof from a plurality of roof elements, superimposing the upper ends of the roof elements on one point, and pivotally supporting the roof elements.

Then, each roof element is rotated and moved in the roof circumferential direction around the center of the roof to open and close the entire roof, and in the fully open state, all the roof elements are overlapped at one place.

[Problems to be Solved by the Invention]

However, with this type of retractable roof, if it is a large roof (see Figures 12 and 13), it is necessary to have a supporting frame that supports the roof top from above the ground, and arch beams for that purpose must be placed on the roof. It needs to be provided separately.

Moreover, since the upper end of the roof element overlaps and overlaps with each other, it is necessary to gradually reduce the beam formation as it reaches the upper part, which complicates the fitting and opening / closing mechanism of this part, and the entire roof It is almost impossible to have a structure that opens almost completely.

Furthermore, since all buildings of this type are generally large in scale, they require a vast site area.

The present invention has been proposed in view of such circumstances, and by maximizing the opening area as much as possible, it is possible to improve daylighting and ventilation at the time of full opening, and to concentric circles of the guide member. By providing the axis P at a position displaced from the split central axis Q of the roof so that the roof element can be opened and closed in a space as narrow as possible (see FIG. 3), the building area can be reduced as much as possible for the scale of construction. It is an object of the present invention to provide a stacking rotary movement type opening / closing structure which can be saved and has an extremely simple opening / closing mechanism.

[Means for solving the problem]

The stacking rotary movement type opening / closing structure according to claim 1 of the present invention is constructed by constructing lower structures on opposite sides of the stadium so as to face each other, and disposing the lower structures on upper ends of the lower structures. , Each roof element of a roof constructed by laying a plurality of sets of two arc-shaped guide members having different radii in concentric circles and dividing the opposing lower structures into a plurality of fan shapes Is installed so as to run and open / close on the pair of two arc-shaped guide members.

The stacking rotary movement type opening / closing structure according to claim 2 of the present invention is constructed by laying the guide member in the shape of a concentric circle centered on a point P different from the dividing center Q of the roof element in the preceding paragraph. Has been done.

When fully open, all roof elements 5 _-1 , 5 _-2 and 5 _-3
Are completely overlapped at both left and right ends.

It is possible to illuminate all parts of Stadium A,
In addition, it is desirable that all roof elements 5 _-1 , 5 _-2 and 5 _-3 have a structure that can be opened and closed in order to be able to carry out repairs and inspections. Only the 5 _-1 and 5 _-2 can be opened and closed, and the roof elements 5 _{-3 at} both ends of the roof may be fixed.

FIGS. 3 and 4 show another stacking rotary movement type opening / closing structure according to the present invention. In the stacking rotary movement type opening / closing structure shown in FIGS. 1 and 2, the guide member 3 is provided.

It is configured. Therefore, the central axes of rotation of the roof elements _5-1 , _5-2 and _5-3 (same as the concentric axes P, P) are slightly displaced from the central axis Q of division of the roof.

With such a configuration, the roof element 5 _-1 is provided under the condition that the concentric circle axis P of the guide members 3 _-1 , 3 _-2 , 3 _-3 , 4 _-1 , 4 _-2 and 4 _-3 and the split central axis Q of the roof are the same. , 5 _-2 and 5 _-3 rotate about the concentric axis P (see FIGS. 1 and 2), the roof elements 5 _-1 , 5 _-2 and 5 _{-3 move} slightly inside. Rotate,
In addition, the opening area when fully opened can be increased (see FIGS. 1 and 2).
Compared to the one shown in the figure, the building area can be saved by the space S indicated by the diagonal lines. As a result, the building area of the building can be saved and the lighting and ventilation at the time of full opening will be very good.

Further, FIG. 11 shows a modified example of the one shown in FIGS. 3 and 4, in which the stacking rotary movable opening / closing structure shown in FIGS. 3 and 4 is vertically or horizontally symmetrical ( In the embodiment, it is constructed vertically symmetrical.) It is constructed by connecting multiple buildings.

According to this embodiment, it is possible to construct a huge dome roof similar to that shown in FIGS. 6 and 7.

〔The invention's effect〕

Since the stacking rotary movement type opening / closing structure according to the present invention is configured as described above, it has the effects described below.

Since the upper end portion of the roof element also travels on the guide member similarly to the hem portion of the roof element, the moving mechanism of the upper end portion of the roof element can be simplified.

Further, when the roof is fully opened, all roof elements can be almost completely overlapped on the left and right sides of the roof, so that the entire roof can be opened to the maximum extent.

Moreover, since both ends of the roof element are supported by the lower structure, it is not necessary to dare to support the upper end portion of the roof element by a supporting frame or the like.

Also, since the upper end of the roof element is not overlaid and pivotally supported, it is easy to fit this part,
It also makes it easier to get out of the rain.

Further, in particular, since the opening / closing means of each roof element is a simple structure, it can be easily built on an existing structure.

Since the roof element can be opened and closed in a relatively small space, the building area of the building can be saved.

In addition, since the opening area at the time of full opening can be maximized, lighting and ventilation are extremely improved.
