Extending High Tensile Anchor Rods with Couplers

There are instances where high tensile anchor rods have been cast in with insufficient projection above the concrete.

There are instances where high tensile anchor rods have been cast in with insufficient projection above the concrete. Extending the anchor rods by welding is generally not permitted. One method to extend the anchor rod is by the use of a threaded coupler. Checks are required to ensure that stripping of the threads and also tensile fracture of the coupler does not occur prior to the tensile fracture of the connected threaded rods. This article presents a method for these checks.
