PROBLEM TO BE SOLVED: To provide a crimping jig with which a disc plate and a waterproof sheet can be sufficiently joined by pressing the waterproof sheet correspondingly to a shape of the disc plate even in the case where the disc plate is deformed in a concave shape when crimping the disc plate and the waterproof sheet in a sheet waterproof structure on the roof of an architectural structure, and a waterproof sheet structure using the crimping jig.SOLUTION: The crimping jig comprises a container and a filler which fills the container, such that a disc plate and a waterproof sheet can be sufficiently joined. A bottom face part of the container filled with the filler smoothly expands towards a substrate surface side without being in contact with any arbitrary surface. |
