Connector seal for an anchor and a corrosion-protection tube of a post-tension system

摘要

A connector for joining a corrosion-protection tube to an anchor of a tendon of a post-tension system including a body formed of an elastomeric material and a seal formed interior of the body. The body has a first receptacle formed at one end thereof for attachment to an end of the anchor. The body has a second receptacle formed at an opposite end thereof for attachment to an end of the corrosion-protection tube. The seal is positioned between the first receptacle and the second receptacle so as to form a liquid-tight seal with a surface of the tendon passing therethrough. The first receptacle is an orifice that has a diameter suitable for liquid-tight engagement with an end of the anchor. The second receptacle is an opening formed in the opposite end of the body and has a diameter suitable for liquid-tight engagement with an exterior surface of the corrosion-protection tube. The orifice and the opening are coaxial. The seal is a membrane which extends transverse to a longitudinal axis of the body. The membrane has a central area with a diameter less than an outer diameter of the tendon. The central area is a hole formed in the membrane.
