PROBLEM TO BE SOLVED: To provide a large-sized temporary roof of an air-beam sheet formed and designed so as to make it possible to carry out work regardless of weather in the external work with new construction work such as erection work of various sixes of houses and apartment houses, waterproofing work, exterior wall painting work or the like or reform and to ensure thereby a construction period of time and quality. SOLUTION: In order to correspond to various sixes, for a gable direction, both ends of an air-beam are pressed in the shape of an arch by rope or the like to make it possible to freely adjust size. Hooks of the air-beam are provided in the direction of a girder in a slidable manner with rope, wire or the like mounted to the head of an upright of a temporary scaffold as a guide. By the constitution, the sheet mounted between both air-beams is loosened, and 2/3 of the area of a roof can be released, if necessary.
