PROBLEM TO BE SOLVED: To provide an opening-closing type membrane roof structure capable of imparting tension to a membrane material by a simple constitution of using a small number of steel frame materials.SOLUTION: An opening-closing type membrane roof structure having a membrane roof 1 in a part of a fixed roof 2, comprises a membrane roof support frame 5 for supporting the membrane roof 1, a roof support rail 10 supported by the membrane roof support frame 5, a plurality of membrane roof units 30 divided along the roof support rail 10 and approach-separation means for approaching-separating the membrane roof units 30 along the roof support rail 10, and the membrane roof units 30 comprise a pair of roof skeleton materials 20 and a small width roof membrane material 31 of a rectangular shape that is installed between the roof skeleton materials 20 or of a paper-strip shape that is wider on an end part side than a central part side, and the roof membrane material 31 is expanded by executing an operation for expanding in a direction for blocking up an opening part from a storage state of folding up the membrane roof units 30 on a side part side of the opening part of a membrane roof by the approach-separation means.SELECTED DRAWING: Figure 8 |
