Description

  The present invention relates to a detaching jig and a detaching method used when repairing a folded plate laid as a roofing material or the like.

Conventionally, when a folded plate roof is formed, a plurality of folded plates are arranged and laid on a roof base such as a purlin, and adjacent folded plates are connected by tightening. This tightening is performed by covering the fitting portion provided at one end in the longitudinal direction of the folded plate (laying side) with the fitting portion provided at the other end in the longitudinal direction of the other folded plate (covering side). After fitting the mating part and the mating part, the mating part and the mating part are fastened and connected by bending using a manual or electric squeezing device (seamer). (For example, refer to Patent Documents 1 and 2). Such tightening is very difficult to remove once tightened. Therefore, when redoing the work due to construction troubles such as noise, or when replacing the folded plate due to deterioration over time, removing the folded plate from the roof requires a great deal of labor and is inefficient. That is, when removing the folded plate from the roof, a large number of workers are lined up on the roof over several meters to several tens of meters, and the worker grasps the longitudinal end (the end portion on the keraba side) of the folded plate to be removed. Pull it up and peel it off. Thereby, one of the folded plates 4 and 4 connected in the state of FIG. 12A can be rotated upward with respect to the other around the portion of the clamp 3 as shown in FIG. ), The fitting portion 1 of the folded plate 4 rotated from the fitted portion 2 of the folded plate 4 that has not been rotated can be removed.
