The present invention provides a beam for a curved structure. A head member (90) is divided into a left side member and a right side member, is formed into a rectangular pipe, and includes bored parts (33, 34) formed at the upper part and the lower part of both sides to connect connectors (20, 21) respectively and bored parts (30, 31) connected to the upper side and the lower side of the head member, respectively. A head member connector includes a bored part (35) of an oval shape formed at the central part in the longitudinal direction in a state where bored parts (40, 41) for connecting the head member are located at the upper part and the lower part from the bored part (35). Connection plates (50, 51) have bored parts (45, 46) of an oval shape formed at both sides in the longitudinal direction. In the beam for the curved structure, the left side member and the right side member are connected to the upper and lower bored parts (30, 31) of the head member by the connection plates. The bored parts (40, 41) of the connectors (20, 21) and the left side member bored part (33) and the right side member bored part (34) of the head member are overlapped in an X shape and are connected by bolts, and the overlapped central bored part (35) is connected by a bolt (80) in the opposite direction in the same way. Moreover, the head member (90) is additionally installed on both sides of the beam so as to form the curved structure. |
