DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building having a dome-shaped roof, and more particularly to a large space used for various purposes such as sports such as baseball and football, and events such as concerts and various exhibitions. The present invention relates to technologies related to facilities such as daylighting in dome-shaped buildings.

[0002]

2. Description of the Related Art Hitherto, a roof has been configured to be a movable roof which can be freely opened and closed, and the roof is opened to form a lighting opening in the interior to receive light.

[0003]

However, according to the above-mentioned prior art, the roof itself is movable and the daylight is taken. Therefore, the roof is opened and closed, that is, a structure for adjusting the amount of light, particularly the roof is opened and closed. The supporting structure for freely supporting and the driving structure for moving the roof have become very large, which has led to an increase in cost. In addition, since the roof is opened for daylighting, an opening is inevitably formed in the roof at the time of daylighting, and the influence of wind and rain is great. That is, at the time of the wind and rain, the wind and rain enter the inside from the opening as in the case without the roof. SUMMARY OF THE INVENTION An object of the present invention is to make it possible to adjust the amount of light to be collected without being affected by the weather.

[0004]

A feature of the dome-shaped building according to the present invention is that a light-transmitting portion mainly composed of a light-transmitting roof material is formed on the roof, and a plurality of light shielding members are provided below the roof. Are arranged in a state where the ends of the adjacent ones are in contact with each other to prevent light from entering the interior from the daylighting unit, and the ends of the adjacent ones of the light shields are vertically separated from each other. Operating means for independently changing the positions of the light shields up and down so as to allow light to enter the interior from the daylighting unit through the gap between the ends of the adjacent ones is provided. The point is that mounting means for hanging mounting is provided. In addition, it is preferable that the light-shielding member is mounted on a roof frame and supported, or that the light-shielding member is provided with a work walkway.

[0005]

[Function] Rather than opening and closing the roof, a fixed roof is provided to the last, a lighting section made of light-permeable roof material is formed on the roof to enable lighting inside, and lighting adjustment means is provided. In addition, since the daylighting adjustment means adjusts the amount of light to the inside, the daylighting amount can be adjusted without being affected by the weather, and the daylighting adjustment means is required to function as a roof. The light-shielding body and its supporting structure and operating means need only be simple while having a movable configuration for adjusting the amount of collected light. In addition, as a lighting adjustment means, a plurality of light shielding bodies and an operation means for changing the position of the light shielding bodies in the vertical direction are provided, and a structure configured to adjust the light amount by changing the position of the light shielding bodies in the vertical direction is provided. Since the light-shielding body acts as a ceiling in a light-shielded state in contact with an adjacent object, it is possible to change the ceiling height and shape by changing the position of the light-shielding body in the vertical direction for adjusting the amount of collected light. it can. In addition, paying attention to changing the position of the light shield in the vertical direction in order to adjust the amount of collected light, the light shield is provided with a mounting means for ceiling-installed equipment that is completely necessary. When performing work on equipment such as installation of equipment and maintenance of equipment, by lowering the light-shielding body near the floor, the work can be performed in low-altitude work excellent in safety and workability. In particular, when the light shield is suspended from the frame, the position of the light shield in the vertical direction can be changed, but interference with the lower space due to the structure for the support can be avoided. When the light-shielding member is provided, adjustment of equipment such as adjustment of the mounting position and orientation of the lighting equipment and the speaker can be performed easily and accurately.

[0006]

According to the present invention, therefore, the structure for adjusting the amount of light to be collected can be implemented at a low cost because it is lightweight, and the height and shape of the ceiling can be adapted to the intended use. The intended multipurpose use can be performed effectively,
It has become possible to provide an all-weather dome-shaped building that can safely and efficiently perform work on equipment such as lighting equipment and speakers. In particular, according to the second aspect of the present invention, while the position of the light shielding body can be freely changed in the vertical direction as described above, the intended use is not made inconvenient. if,
It can be used more conveniently.
