DRY-TYPE WATER STOP STRUCTURE OF INTERSECTION OF JOINTS OF EXTERIOR WALL

PROBLEM TO BE SOLVED: To provide a dry-type water stop structure of an intersection of joints of an exterior wall by which a reliable water stop can be obtained only by a dry system even when deviation etc. are observed in construction of the exterior wall, and incorporation of parts etc. or construction is facilitated as the structure is simple. SOLUTION: A dry-type first water stop material 7 extends on a back side of exterior wall surface materials 1a, 2 along a vertical joint 4 on upper and lower sides of a horizontal joint 5 in a manner of piercing the horizontal joint 5. The dry-type first water stop material 7 is wider than a width dimension of the vertical joint 4. Both side parts 7a, 7a of the first water stop material 7 project on the back side of the exterior wall surface materials on right and left sides of the vertical joint 4. A water-stop fillet 7b extending vertically is arranged on a front side of each of the projecting parts. The fillet prevents the water from entering to the further depth and forms a state of water stop. A dry-type second water stop material 8 is arranged on the vertical joint 4, and a dry-type third water stop material 9 is arranged on the horizontal joint 5. Thus, water stop is achieved only by dry system. COPYRIGHT: (C)2011,JPO&INPIT
