My design features hollow leveling feet. The feet go through the baseplate, with a pair of nuts above and below the baseplate, to allow for leveling the baseplate relative to the ground. The bottom of the levelling foot features a pad that rests on the ground. Each levelling foot is hollow, to allow an anchoring rod to through the center. The anchor rod is then tightened on top of the leveling foot. It is not possible to clamp the anchoring rod to the ground (since the leveling foot is around the anchor), therefore this is not "stand-off with clamping." If grouted, the grout would sit around the levelling foot and not directly the anchor rod, perhaps this is not "Stand-off with grouting?"
I would like to use internally threaded anchors, so "stand-off without clamping" is not an option, and this is clearly not "no stand-off."
How can I best model this design? What is the correct stand-off condition?
Hi Jean-Pierre,
For assistance with modeling stand-off conditions, many design engineers will look to using the PROFIS Engineering design software. Please click here to access the software from Hilti's website. Starting on page 318 of the PROFIS Design Guide, different ways to model stand-off conditions as well as how the software calculates stand-off without clamping, stand-off with clamping, and stand-off with grouting are explained.
If you have any further questions, please reach out to hnatechnicalservices@hilti.com.
Best,
