[TowerTalk] Concrete anchors

[Andre VanWyk]

I have a concrete base next to my shop that once had 89ft US Crankup Tower
on it. The tower is gone, and I acquired a 55ft US Tower that I want to bolt
to this base for use in my shop. The bolts that once held the bigger tower
is still there, but I plan to cut them off and install chemical anchors to
support the smaller bolt pattern. The other option was to fabricate an
adapter plate that would mate the 55ft tower T-base to the bigger bolt
pattern, but this sounds like much more work than simply drilling into the
concrete and installing new anchors.

 

I never used chemical anchors for this purpose and would appreciate any
suggestions on size, and where I can source them. The rebar pattern for the
bigger tower is much wider than the bolt pattern for the smaller tower, so I
there is little chance for me to hit rebar when I drill. (I suspect I will
need a BIG drill).
