PROBLEM TO BE SOLVED: To provide a membrane roof unit and an opened/closed-type membrane roof structure that may be opened/closed without excessively deforming a roof membrane material, and is compatible with a roof that opens in two lateral directions and a roof of a complicated form, thereby resolving problems with conventional techniques.SOLUTION: A membrane roof unit of the present invention includes a V-shaped frame disposed in an opening/closing shaft direction, a skeleton frame disposed in a direction orthogonal to the opening/closing shaft direction, a roof membrane material, and an expansion device that expands/contracts in a vertical direction. An overall configuration includes a plurality of skeleton frames arranged almost in parallel with each other, and the V-shaped frames on right and left are disposed on a side of the skeleton frames that face each other. The roof membrane material has a folding part for folding the roof membrane material along the opening/closing shaft direction. The expansion devices on right and left are disposed at both ends of an upper beam. When the expansion device is expanded downward, the V-shaped frame spreads in the opening/closing shaft direction. When the expansion device is contracted upward, the V-shaped frame is folded along the opening/closing shaft direction.SELECTED DRAWING: Figure 3 |
