Effect of the Invention As described above, according to the present invention, a roof frame having one side is taken out by installing an isosceles triangular roof frame with one side thereof taken out to the eaves side. However, there is an effect that the eaves on the outer corridor side can be largely taken out. In this case, on the take-out side, since it is installed on the frame through the bundle material below the upper chord material, it can sufficiently support the vertical load acting on the upper chord material side, and
The brace provided in this portion can also oppose a horizontal force. When the isosceles triangular shed frame is used, the upper chord members constituting the frame can use the same member having the same length, and the load in the left-right direction across the top is not so large. Since there is no significant change, the installation work can be easily performed while maintaining the horizontal state even in the suspended state. .
