Abstract
A joint seal is designed to maintain its proper position in the joint groove opening port to create an effective seal between the inner walls of the joint groove and to resist peeling or damage, even in an event, such as an earthquake, during which the adjacent outer wall materials shift; and to have a joint base material 2, a sealing material 3 and a heart wood 8. The joint base material 2 has at least two seal tongue pieces 14a and 14b projecting from the outer face of side plates 5, 5. A number of small openings 8 to allow sealing material to be pressed out at the insertion of heart wood 8 is punched between the seal tongue pieces 14a and 14b, and release mold sheets 18a and 18b are attached to joint base material 2 as a cap member covering the small openings 8 and the opening ports of side plates 5, 5.
