    • PROBLEM TO BE SOLVED: To provide a flexible water stop joint enabling a preparation working before concrete is deposited to be performed easily in a short time when a structure is constructed by continuously depositing the concrete and a method of installing the water stop joint. SOLUTION: This flexible water stop joint comprises a pre-deposit fixed part 21 and a post-deposit fixed part 22 fixedly buried by depositing in a preceding and following concrete structures, an extension part 23 formed therebetween and enabling water sealing and a relative displacement, and a support member 24 formed integrally with or separately from the flexible water stop joint 20, installed in an end type frame for concrete deposition deposited earlier, buried in the deposited concrete, and capable of supporting the flexible water stop joint 20 before concrete deposition. Accordingly, since the preceding concrete may be deposited while supporting the pre-deposit fixed part 21 through the support member 24 installed on the end type frame, the support member 24 and the flexible water stop joint 20 can be installed before the end type frame is installed. As a result, a special end type frame is not required, and the installation of the water stop joint can be performed by using a normal end type frame. COPYRIGHT: (C)2007,JPO&INPIT
