Abstract
For the purpose of making joints in external walls long life, adjacent double Sealed joint system is proposed.Proposed joint system is composed of two adjacent sealants.Sealant is silicone which is used inside for higher water-tight reliability. The other sealant is polyisobutylene and so on which is used outside for retention of appearances.With movement of temperature, wind and so on, faigue resistance of Proposed joint system is worse becuase of interference with two sealants movement.As a result,faigue resistance of proposed joint system is effectd by depth of sealants and silicon sealant movement's interference with inside sealant. And It was found that proposed joint system has best form.Moreover it is found that faigue resistance of proposed joint system is shown using quantity of all sealants depth,wide and outside sealants depth and inside(silicone) sealants depth.
