Description

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 specifically, it forms a large space used for various purposes such as sports such as baseball and football, events such as concerts and various exhibitions. This relates to equipment-related technologies such as daylighting among dome-shaped buildings.

[0002]

2. Description of the Related Art Conventionally, the roof is a movable roof that can be freely opened and closed, and the roof is opened to form a lighting port to the inside for lighting.

[0003]

However, according to the above-mentioned conventional technique, since the roof itself is movable to illuminate, the roof is opened and closed, that is, the structure for adjusting the amount of light, particularly the roof is opened and closed. The support structure for supporting freely and the drive structure for moving the roof have become very large-scale, which has led to an increase in cost. In addition, since the roof is open for lighting, an opening is inevitably formed on the roof during lighting, which is greatly affected by wind and rain. In other words, in the case of wind and rain, wind and rain enter the inside through the opening as in the case without a roof. An object of the present invention is to make it possible to inexpensively construct the equipment and to adjust the lighting amount without being influenced by the weather.

[0004]

The feature of the dome-shaped building according to the first aspect of the present invention is that a daylighting section mainly composed of a light-transmissive roof material is formed on the roof, and below the roof, The plurality of light shields are arranged in a state in which the ends of adjacent ones are in contact with each other to prevent light from entering the inside from the lighting unit, and the ends of the adjacent ones of the light shields are vertically arranged. An operating means is provided for vertically changing the positions of the light shields independently of each other so as to allow the light to enter the interior from the light collecting portion through the gap between the ends of the adjacent ones that are separated from each other. The point is that the lower surface of the body is made of sound absorbing material. The feature of the dome-shaped building according to the second invention of the present invention is that, in the above-mentioned first invention, the daylighting part is formed in a central part of the roof, and as the light shielding body, it is on a vertical axis passing through the center of the daylighting part. A central light shield located and a ring-shaped light shield positioned concentrically with the central light shield are provided, and the central light shield of the light shields is located at the lowest position, and the ring light shield is closer to the outer side in the radial direction. It is configured such that the end portions of the light shields that are adjacent to each other in the radial direction are in contact with each other in the state where they are arranged so as to be positioned at the upper position so as to shield light. The dome-shaped building according to the third invention of the present invention is characterized in that, in the first invention and the second invention,
The end portions of the light shields adjacent in the radial direction are configured to overlap each other in the vertical direction, and between the end portions of the light shields adjacent in the radial direction overlap in the horizontal direction, the light shields adjacent to each other in the radial direction are arranged in the horizontal direction. This is in that a seal material is interposed to block the space below the light shield and the space above the light shield in a state where relative displacement is allowed.

[0005]

According to the first aspect of the invention, instead of opening and closing the roof, a fixed roof is provided, and a daylighting section made of a light-transmissive roof material is formed on the roof to enable daylighting inside. After that, the lighting adjustment means is provided, and the amount of lighting to the inside is adjusted by the lighting adjustment means.
The lighting amount can be adjusted without being affected by the weather, and the lighting adjustment means is not required to have a function as a roof.
A light-shielding body and its supporting structure and operating means are simple. Moreover, as the lighting adjustment means, a plurality of light shields and an operation means for vertically shifting the light shields are provided, and the light adjustment amount is adjusted by vertically shifting the light shields. Therefore, since the light shield acts as a ceiling in a light shielded state where it is in contact with an adjacent object, it is possible to change the ceiling height and shape by changing the vertical position of the light shield for adjusting the amount of light. it can. In addition, paying attention to the fact that the light shield forms a ceiling for adjusting the amount of light, and the lower surface of the light shield is made of sound absorbing material, so that a large space is formed on the ceiling. Can be absorbed to reduce the reverberation time, and the acoustic characteristics can be adjusted by appropriately adjusting the vertical position of each light shield. According to the second aspect of the invention, since the light shield that also serves as the sound absorbing plate changes the ceiling height and the shape by changing the position in the vertical direction for adjusting the amount of light, the roof height is the highest. Since the height of the ceiling formed by the light-shielding body in the high central portion is set to the lowest position, it is possible to secure a sufficient roof height when the light-shielding body is located at the top. Also, in the light-shielded state, the air volume of the space under the ceiling can be made sufficiently small, and the reverberation time can be further shortened. According to the third aspect of the invention, since the relative displacement in the lateral direction of the light shield is allowed in a state where the end portions of the adjacent light shields are in contact with each other, it is easy and simple to support the light shield. On the other hand, even when adopting a suspension system in which shaking of the light shield due to the occurrence of an earthquake is unavoidable, the individual shaking of the light shield due to the occurrence of the earthquake is not allowed and an unreasonable force is not applied to the contact part. .

[0006]

According to the present invention, therefore, the structure for adjusting the amount of light is lightweight and can be implemented at low cost, and the ceiling height and shape can be adapted to the intended use. The desired multi-purpose use can be done effectively, and moreover,
It is now possible to provide an all-weather dome-shaped building that has a large reverberation time and excellent acoustic characteristics even in a large space. In particular, according to claim 2, it is possible to further improve the acoustics by reducing the air volume, and according to claim 3, the light shield is provided with low strength and light weight, and the light shield is installed. While advantageously performing, it is possible to prevent the light shielding body from being deformed and damaged in the event of an earthquake and to improve the durability of the light shielding body.
