发明名称 Concrete expansion joint
摘要 A concrete expansion joint and seal assembly includes opposed generally planar side frame members with spaced apart flanges forming channels which are operable to bond the side frame members to opposed sections of concrete when the expansion joint is placed in its working position. A flexible seal member includes a loop portion and opposed legs coextruded with and bonded to edges of the side frame members. The side frame members are temporarily held contiguous with each other at their respective distal ends by adhesive tape, an adhesive or a hook portion formed on one of the side frame members for engaging the distal end of the other side frame member. The seal member is preferably formed of an extrudable thermoplastic elastomer and the side frame members are preferably formed of extrudable polypropylene.
