Multi-strand anchorage system with an anchor body for receiving a grout tube
First Claim
1. A multi-strand anchorage system comprising:
- an anchor body having a tendon-receiving area therein, said anchor body having a channel extending through a wall thereof, said channel extending transverse to said tendon-receiving area, said channel opening at an exterior of said anchor body, said channel communicating with said tendon-receiving area, said anchor body being of a steel material; and
a grout tube means extending through said channel so as to have an outlet opening toward said tendon-receiving area, said grout tube means having a pronged exterior surface adjacent said outlet of said grout tube means, said pronged exterior surface in abutment with a surface of said anchor body, said grout tube means for passing grout to said tendon-receiving area.

Abstract
A multi-strand anchorage system having an anchor body with a tendon-receiving area therein and a channel extending through a wall thereof, and a grout tube extending through the channel so as to have an outlet opening to the tendon-receiving area. The channel opens at an exterior of the anchor body and communicates with the tendon-receiving area. The grout tube has a pronged exterior surface adjacent the outlet of the grout tube. The pronged exterior surface is in abutment with a surface of the anchor body. The grout tube serves to pass grout to the tendon-receiving area. The grout tube has a shoulder formed a distance from the outlet and having a diameter less than the diameter of the channel. An elastomeric annular seal is affixed around the grout tube so as to be in abutment with a shoulder of the grout tube and in compressive abutment with a shoulder in the channel.
