DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a movable dome roof structure.

[0002]

2. Description of the Related Art In an openable dome such as that found in the Fukuoka Dome Stadium, for example, a bowl-shaped roof divided into three sections at about 120 ° turns around the top of the roof, and when weather is good, it is outside. Connect with the space and become an outdoor stadium. In this type of equipment, there is no change in the internal facilities themselves, and only the opening and closing of the roof is performed.

[0003]

A structure having a roof structure of this kind is a huge building. In addition to sports sports such as baseball, for use as a venue for a concert, for example, the audience stand has a stage and a stage. Because it surrounds a relatively large area of ground, which is a large area, it has disadvantages such as being far from the stage, and if the whole is closed, there is a problem with reverberation, etc. It was used only as an event venue for popular music, which rarely relied solely on electrical sound reproduction.

Accordingly, the present invention enables the dome roof to be opened and closed as if it were a bivalve, and provides an acoustic lens effect in accordance with the degree of opening and closing of the dome roof. Further, it is an object of the present invention to provide a movable dome roof structure which is a space between an indoor space and an external environment, and which reduces a feeling of obstruction peculiar to a dome architecture.

[0005]

In order to achieve the above object, according to the first aspect of the present invention, there is provided a dome roof structure in which an upper surface of a lower structure having an audience stand therein is covered with a dome roof. In the object, one end of the dome roof is connected to a lower structure via a hinge, and the other end of the dome roof is supported so as to be openable and closable via an elevating mechanism. The dome roof can be used as an acoustic lens according to the degree of opening and closing.

In the invention according to claim 2 of the present invention, since the roofing material of the dome roof is formed of a transparent plate, even when the roof is closed, it is possible to maintain contact with the outside world such as daylighting.

According to a third aspect of the present invention, a movable wall is disposed around a movable portion of the dome roof, and a space or dome formed between the lower structure and the dome roof when the roof is opened. By closing the inside of the building by overlapping it on the roof, it is possible to adjust the lighting and temperature inside, etc., as a space between the indoor space and the external environment,
Relieves the feeling of blockage peculiar to dome architecture.

According to the fourth aspect of the present invention, the movable wall can be expanded and contracted by a shutter type or a louver type, so that a light shielding structure can be obtained.

[0009] The invention according to claim 5 of the present invention is characterized in that the audience seat stand inside the lower structure can be moved, for example, when used as a concert hall.
The interior can be easily remodeled to a concert venue style, and it can be adapted to small events depending on the layout of the audience stands.

[0010]

Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings. FIG.
4 to 4 show a movable roof dome according to the present invention and a shape-changed state thereof.

In each of the figures, the lower structure 1 constructed in an annular or elliptical shape is formed so that one side of the lower structure 1 is low and the other side thereof is continuous in a high shape.
A plurality of stands 2 which are divided into a plurality of blocks and have a multi-stage audience seat facing inward are installed movably.

Dome roof 4 arranged on the substructure 1
Is a frame 6 of a lightweight arch structure rotatably supported at one side at the lowest position of the lower structure 1 via a hinge 5.
And a transparent roofing material 7 such as tempered glass, acrylic resin glass or the like laid on the frame 6, and a lifting mechanism 8 such as a plurality of hydraulic cylinders between the lower edge and the lower structure 1. Are linked.

A take-up device 9 is arranged around the dome roof 4, and a shutter 10 for shielding is housed inside the take-up device 9 in a deployable manner.

FIG. 1 shows a fully closed state of a dome roof 4 which is a basic use shape of the movable roof structure.
The entire dome roof 4 covers the upper part of the lower structure,
Despite this closed state, the connection with the external space is maintained by the transparent roofing material 7.

From this state, by simultaneously extending the elevating mechanisms 8, as shown in FIG.
It is raised from the hinge 5 as a base, and changes into a state as if the shell of a shell is opened. In this state, air can flow to the outside, and the sense of opening can be further widened.

Further, the roof shape is low at one end and high at the other end, so that the dome roof 4 itself can be used as an acoustic lens, and the stands 2 are moved and the arrangement is the same as that of the concert hall. By arranging it, it is possible to recreate a venue suitable for large concerts.

In order to further maintain the inside of the structure in an air-conditioned atmosphere from the above state, as shown in FIG. 3, the shutter 10 is lowered by the winding device 9 so that the dome roof 4 is lifted. Closed space.

In some cases, it is desirable to artificially create a shade depending on the state of the sunshine or the like.
Of course, it is possible to raise the shutter from the side and cover a part or the whole of the outer surface of the dome roof 4.

FIG. 4 shows a case where the above-mentioned building is applied to an event such as a relatively small concert. The blocks of each stand 2 are appropriately selected and moved, and a temporary stage provided at the center thereof is provided. A small, independent venue is built inside the structure with an arrangement surrounding 11.

[0020]

As is apparent from the above description, in the movable dome roof structure according to the first aspect of the present invention, the dome roof is used as an acoustic lens according to the degree of opening and closing with the hinge side as a base point. Since it can be used, it is suitable not only for use as a baseball or other stadium, but also as a venue for music events such as concerts.

By adopting the structure of claim 2,
Even when the roof is closed, contact with the outside world such as daylighting can be maintained, and the space between the indoor space and the external environment can be set as an intermediate space, and the feeling of blockage peculiar to the dome architecture can be reduced.

By adopting the configuration of the third aspect, it is possible to control the lighting and the internal temperature.

By adopting the structure described in claim 4, a light-weight shielding structure can be obtained.

By adopting the configuration according to the fifth aspect, for example, when used as a concert hall, the interior can be easily remodeled into a concert hall style, and a small event can be handled according to the arrangement of the audience stand. It can correspond to various uses such as being able to be performed.
