PROBLEM TO BE SOLVED: To provide a construction method of a semispherical construction with which assembly work can be performed by a small number of workers without requiring any heavy machine such as a crane, a construction constructed by the construction method and a triangular structure therefor.SOLUTION: In a semispherical construction A, from a first layer wall surface 1 up to a fifth layer wall surface 5 are constructed in wall surface construction steps. From the first layer wall surface 1 to the fifth layer wall surface 5 are comprised of a first triangular structure T1 or a second triangular structure T2. According to the construction method, since the triangular structure is assembled as a unit, it becomes comparatively lightweight, the need of a heavy machine such as a crane for suspension is eliminated and construction work can be performed by a small number of workers. Furthermore, the construction constructed by the method is structured by combining a pentagonal pyramid shaped wall surface and a hexagonal pyramid shaped wall surface in the triangular structure, and the semispherical construction is constructed. Moreover, since the triangular structure can be made into a member in the state of dividing the pentagonal pyramid shaped wall surface and the hexagonal pyramid shaped wall surface into a plurality of parts, the member can be made lightweight. |
