[Function] A large building equipped with a retractable large roof according to the present invention,
A shell framework is formed by joining a shell-shaped steel framework that is curved upward in front view and a shell-shaped steel framework that is curved downward in front view at least at both ends thereof to form a roof framework. A plurality of control strings are arranged between the both ends of the skeleton at intervals in the moving direction of the roof, and both ends of each control string are connected to the ends of the roof skeleton so that the roof skeleton is self-assembled. Since the structure of the balance system is adopted, the both ends of the roof frame are supported by the transfer body, and the roof material is attached to the roof frame to construct the openable roof, so wind, earthquake, and snow fall on the openable roof. Even if an abnormal force such as the above acts, the structure of the self-balancing system can be maintained by controlling the control string according to the force acting on the roof. Therefore, the horizontal displacement of the end portion of the roof frame structure can be constantly suppressed to zero, and the large roof can be opened and closed smoothly.
