Abstract
An anchor for a post-tension system has an anchor body having an end surface. Encapsulation covers the anchor body; the encapsulation extends outwardly from the end surface and has a retaining groove on an exterior surface of the encapsulation on an end of the encapsulation opposed to the end surface. A cap has a generally tubular body with an open end and a closed end; the cap has a flange adjacent the open end. The flange has a plurality of circumferentially spaced apart locking features, or a circumferentially continuous locking feature, extendable over the end of the encapsulation and engageable within the retaining groove.
Claims16
An anchor for a post-tension system comprising:
- an anchor body having an end surface;
- encapsulation covering the anchor body, said encapsulation extending outwardly from the end surface and having a retaining groove on an exterior surface of the encapsulation on an end of the encapsulation opposed to the end surface and
- a cap having a generally tubular body with an open end and a closed end, the cap having a flange adjacent the open end, the flange having a plurality of circumferentially spaced apart locking features, or a circumferentially continuous locking feature, extendable over the end of the encapsulation and engageable within the retaining groove.
An anchor for a post-tension system comprising:
- an anchor body having an end surface;
- encapsulation covering said anchor member, said encapsulation comprising a tubular section extending outwardly from said end surface and a retaining groove on an exterior surface of the encapsulation on an end of the encapsulation opposed to the end surface;
- and
- a cap having a generally tubular body with a first open end and a second open end, said cap having a flange adjacent to said first open end, said flange having a plurality of circumferentially spaced apart locking features, or a circumferentially continuous locking feature, extendable over the end of the encapsulation opposed to the tubular section and engageable within said groove, said cap having a locking feature on the second open end to retain a first flexible tube attached to the cap proximate the second open end.
An anchor for a post-tension system comprising:
- an anchor body having an end surface;
- encapsulation covering the anchor body, said encapsulation extending outwardly from the end surface;
- and
- and a rigid ring disposed inside the encapsulation on the side opposed to the end surface, the rigid ring comprising a groove on its exterior surface to engage a locking feature on an interior surface of the encapsulation.
