Title:
JOINT WATER-STOPPING COUPLING OF STRUCTURE
Document Type and Number:
Japanese Patent JP2021116635
Kind Code:
A
Abstract:
To provide a joint water-stopping coupling for a structure that can follow the displacement of a joint of the structure in any direction to absorb the displacement and maintain water sealing, and does not provide excessive quality at joint intersections or otherwise.SOLUTION: There is provided a joint water-stopping coupling 10 of a structure comprising: a first water-stopping member 20 that includes a first elastic part 21 expanding and contracting in an orthogonal direction of a joint 2, and first fixing parts 22 to a flat plate-like structure 1 arranged on both sides of the first elastic part 21; and a second water-stopping member 30 that is arranged in an intersection region 32 in which the first water-stopping member 20 surrounds a joint intersection part 31 corresponding to the shape of the joint 2, and includes an annular elastic part 34 arranged in an annular shape at the center of the intersection region 32 and expanding and contracting, a second elastic part 35 arranged between itself and the first water-stopping member 20 adjacent to the intersection region 32 and expanding and contracting, and a second fixing part 36 to the flat plate-like structure 1 arranged outside the second elastic part 35. The first water-stopping member 20 and the second water-stopping member 30 are integrally formed into a shape corresponding to the shape of the joint 2.SELECTED DRAWING: Figure 1
