PROBLEM TO BE SOLVED: To provide a water stop plate correction jig that reliably prevents deformation due to own weight of the water stop plate by simple installation work to normalize an arrangement state of the water stop plate, and thereby enable securing the water stop performance of a concrete skeleton.SOLUTION: A water stop plate correction jig holds an end 4a of a water stop plate 4 buried astride between opposing concrete skeletons, and prevents sagging of the end 4a by the own weight of the water stop plate 4 in the placement of concrete 9. The water stop plate correction jig includes a water stop plate installation part 2 and a skeleton abutment part 3. The water stop plate installation part 2 is installed in the end 4a of the water stop plate 4 to bend and lift the end 4a. The skeleton abutment part 3 comes into abutment with a skeleton 6a, the water stop plate installation part 2 is inclined upward from the skeleton abutment part 3 and extended, the own weight of the water stop plate 4 and the elastic force with the deformation of the water stop plate 4 are applied to the water stop plate installation part 2, and the skeleton abutment part 3 presses the skeleton 6a by receiving a load of the water stop plate installation part 2. Thereby, the water stop plate 4 is supported between the end 4a of the water stop plate 4 and the skeleton 6a.SELECTED DRAWING: Figure 1 |
