摘要

A dome-shaped roof structure for a large construction such as an athletic stadium, capable of partly opening according to the environmental conditions such as weather condition. The dome-shaped roof structure comprises a dome-shaped stationary roof section having a central opening and fixedly secured at an outer periphery thereof to the external wall of the construction, and a plurality of movable roof units each having a shape to cover one of a plurality of divisions of the central opening and pivotably secured at one end thereof to a support located near the circumference of the central opening so as to be turned between a first position where the central opening is closed and a second position where the same is opened. According to the present invention, a method of constructing the stationary roof section in the above openable roof structure is also provided.
