Hello all,
I have an existing concrete base of several yards of concrete that i want to
mount a vertical to.
I plan on using a 2 1/2 inch OD , 36 inch long, piece of steel or aluminium
tubing (thick wall) with the end welded to a flat plate with gusset plates
every 90 degrees. This plate would bolt to the concrete with anchor bolts
epoxied into holes bored in the concrete.
My questions:
1) How do I calculate the size and thickness of the plate and gusset material?
2) How many bolts and bolt diameter needed? Bolt length needed in the
concrete?
3) Should I use steel or aluminum? This is coastal FL so there is some salt
to contend with. Steel would probably be painted unless I can find a local
galvanizing vendor.
4) the other thing I thought of doing was boring a 2 1/2 + inch diameter hole
and just epoxying in the tubing. Not sure how to bore a hole that large and
deep. Maybe hire someone to do this?
Suggestions? I don't wsnt to over complicate or engineer this either.
