FORMATION METHOD OF JOINT WATER-STOPPING COUPLING AND JOINT WATER-STOPPING COUPLING STRUCTURE OF STRUCTURE

PROBLEM TO BE SOLVED: To provide a formation method of a joint water-stopping coupling which is superior in pressure-resistance performance than ever while securing displacement-following performance of following the displacement between structures. SOLUTION: The joint water-stopping coupling 12 is formed which covers the cross-shaped joint 32 among a plurality of structures 30, and is made possible to follow the displacement among the structures 30. The joint water-stopping coupling 12 is formed by the formation method of the joint water-stopping coupling which consists of a first fixation process and a second process. The first fixation process is for fixing a fixation member 22 to a strip-shaped flexible water-stopping member 14 having a size large enough to cover the joint in a maximum displacement state by estimating the maximum displacement state where the displacement between the structures 30 becomes the predetermined maximum admissible displacement. The fixation member 22 is used for fixing the flexible water-stopping member 14 to the structure which is in a maximum displacement state. Then the second process sets the structure 30 in a state other than the maximum displacement state, arranges the flexible water-stopping member 14 so that it covers the joint 32, and fixes the flexible water-stopping member 14 by using the fixation member 22. Thus, the joint water-stopping coupling is made more excellent in pressure-resistance performance than ever while securing displacement-following performance. COPYRIGHT: (C)2008,JPO&INPIT
