PROBLEM TO BE SOLVED: To provide a lift-up method for a roofing material that lifts up a roofing material while suppressing deformation of the roofing material, and then connecting the roofing material to a top part of a building frame.SOLUTION: A lift-up method for a roofing material includes the following steps of: erecting leg part steel frames 12, 14; erecting a ring-form roofing material 18 by connecting a pair of arched roof steel frames 20 using a connecting member 22 and leaving an interval, on a ground inside the leg part steel frames 12, 14; and spanning a tensile reinforcement member 24 between edge parts 20A, 20B on both sides in a longer-side direction of the roof steel frame 20. Then, the roofing material 18 is lifted up while supporting the edge parts 20A, 20B on both sides in the longer-side direction of the pair of roof steel frames 20, and the roofing material 18 is connected to a top part of the leg part steel frames 12, 14.SELECTED DRAWING: Figure 1 |
