Description

TECHNICAL FIELD The present invention relates to a dome capable of opening and closing a roof portion.

[Prior Art and Problems to be Solved by the Invention]

Various proposals have been made for this type of dome, but in general, the dome roof that covers a large area and a large space has a complicated opening and closing mechanism, which tends to be a large-scale one, and at the time of its opening and closing operation. In, since it is a long one, it tends to be structurally unstable. For these reasons, the conventional roof opening / closing dome has a complicated opening and closing mechanism for the dome roof, and the dome roof is structurally stable. It tends to be extremely expensive with a long construction period.

On the other hand, if the opening / closing mechanism is complicated, maintenance is troublesome, and much time and cost are required. Also, if a new dome roof is to be made that makes the opening / closing mechanism simple and makes the dome roof itself structurally stable when opening / closing, in this case as well, the development period of the new dome roof In addition, a large amount of time and cost such as development cost is required.

The present invention was devised in view of the above-mentioned circumstances, and the purpose thereof is not required to develop a new technology, the opening / closing mechanism of the dome roof can be simplified, and the structure at the time of opening / closing the dome roof can be achieved. The object of the present invention is to provide a roof opening / closing dome which can obtain stable stability and can have a simple structure.

[Means for Solving the Problems]

According to the present invention, the roof opening / closing dome is laid over the dome roof portion formed of a plurality of fan-shaped unit shells and above the dome roof portion as a separate body from each of the unit shells. It is composed of an arched beam-shaped spanning frame structure. In addition, each of the unit shells is supported by a rotating shaft at a position where an upper end of the unit shell is the dome center of the arch portion, and is rotatably movable by a traveling device at the lower end around the rotating shaft. At the position inside the one unit shell, each of the remaining unit shells can be sequentially moved at the position inside the unit shell.

Since each unit shell of the dome roof is supported by the structurally stable spanning frame, it is possible to open and close each unit shell by making it structurally stable during stop and rotation. The mechanism has a simple structure,
Further, the dome can be made to have a simple structure composed of a spanning frame part and a dome roof part.

And the dome roof part 3 is divided into six equal parts, and both base parts of the spanning frame part 4 are also made into the same shape. Further, the remaining unit shells 2 facing each other are formed by dividing the dome roof portion 3 into 12 equal parts.

As described above, the dome roof portion 3 of the roof openable dome 1 of the present invention is formed by the unit shells 2 each having a shape in which the dome roof portion 3 is equally divided, and the unit shells 2 having different shapes are combined. Can also be formed.

[Advantages of the Invention] A roof opening / closing dome of the present invention is a dome roof portion formed of a plurality of fan-shaped unit shells, and a unit above the dome roof portion, which is separate from each of the unit shells. It is composed of an arch beam-like straddling frame part that is bridged over. Further, each of the unit shells is supported by a rotating shaft at a position where an upper end of the unit shell is the dome center of the bridging frame part, and is rotatably movable by a traveling device at the lower end around the rotating shaft. At a position inside the at least one unit shell, each of the remaining unit shells is sequentially moved at a position inside the unit shell.

Further, according to this structure, since each unit shell of the dome roof is supported by the structurally stable arch-beam-shaped spanning frame structure, each unit shell is structured at the time of stop and rotation movement. Can be kept stable.

Therefore, since an excessive force is not applied to each unit shell, the traveling device at the lower end portion thereof, that is, the opening / closing mechanism can be simplified. From this, the construction period of the dome can be shortened, the construction cost can be reduced, and the maintenance after completion can be easily performed. Can be provided.

Further, since the spanning frame part and each unit shell which is the dome roof part are separate bodies, a gap is created between the spanning frame part and the dome roof part. Therefore, this gap can be used as a storage portion for building equipment of the dome.

The rotation shaft is biaxial, and each unit shell of the dome roof is divided into two sets of the same number of sheets, and each set is supported by each of the above-mentioned rotation shafts. Can be simple.

In addition, it is possible to reduce the overlapping size when the unit shells of the dome roof are overlapped. Therefore, each unit shell does not largely project to the lower surface of the spanning frame portion, and the space on the lower surface of the spanning frame portion can be widened, and the space can be effectively used.

The spanning frame is rotatably movable around the dome centering on the center of the dome by a track laid near the dome, and it runs horizontally between the position above the roof of the dome and the position outside the dome. It shall be movable in any direction.

As a result, it is possible to set the bridging frame part in a bridging state at any position and to open the dome roof part 100%. The ability to move between the dome roof upper position and the dome outer position also allows the dome roof to cover the top of the facility adjacent to the dome other than the dome.
