Description of the Related Art Conventionally, a large roof having a pillarless dome structure is generally formed into a spherical shape using a part of a spherical shape due to a mechanical structure. In recent years, many of the large roofs are configured as membrane roofs.
Even in this case, the membrane roof is expanded and used in a spherical shape by pressing the inside of the dome.

大幅に高められる。According to the first structure of the dome roof structure according to the present invention having the above structure, three or more arch beams projecting in the circumferential direction of the annular beam are inclined outward as they go upward. Since the roof membrane was attached between the upper side of these arch beams and the side part surrounded by the arch beam and the annular beam, the roof membrane was lifted by the arch beams at the periphery of the roof, and the roof membrane was lifted at the center of each arch beam. Can be set to be substantially the same as or higher than the center of the roof. Therefore,
The feeling of oppression at the periphery of the roof is eliminated, and the space inside the dome can be widely used. In addition, the use of the arch beam to support the roof membrane significantly improves the support strength of the roof membrane. Further, since the curved portion at the upper end of each of the arch beams protrudes obliquely upward from the peripheral edge of the roof, the roof membrane is smoothly and continuously covered with a three-dimensional curved surface at each curved protruding portion, The appearance of the roof is significantly improved, and its value as a building is greatly enhanced.

幅に向上される。In the second structure of the dome roof structure according to the present invention, as in the first structure, three or more arch beams are inclined and protruded from the annular beam, and at least these arch beams are provided. A large number of cables were stretched between the arch beams, and a roof membrane was attached between the upper portions of the arch beams and on the side portions surrounded by the arch beams and the annular beams. As with the configuration, it is possible to eliminate the feeling of oppression in the dome, increase the support strength of the roof membrane, and increase the value as a building, as well as the cable stretched between each arch beam. Since the cable can bear a part of the load of the arch beam inclined outward as going upward, the supporting strength of the arch beam is greatly improved.
