PROBLEM TO BE SOLVED: To provide a water-sealing joint structure for water-sealing a joint between secondary products of concrete, which can prevent a great displacement to avoid a large step or groove, and which can suppress an increase in cost. SOLUTION: This joint structure is used for water-sealing a gap between the first secondary product 7A of concrete and the second secondary product 7B of concrete. The joint structure comprises a first water-sealing material 5 which is at least partially embedded in the secondary product 7A, and a second water-sealing material 1 which is at least partially embedded in the secondary product 7B. A recess 25 is formed in the material 5 inside the secondary product 7A; and a protrusion 1a is formed on the material 1, and fitted into the recess 25. COPYRIGHT: (C)2007,JPO&INPIT
