There was a comment made regarding welding tower bolts together at the
base to ease installation. I ran into problems with my recent
installation and have a plan for my next tower base. :-)
I built the base per the engineering drawings, and hung the 4' long
bolts from the tower baseplate per the factory recommendation. When we
poured the concrete into the hole, the bolts were just hanging there,
flapping the the breeze, so to speak. We had to halt the pour to
reposition the bolts three times, and they never did end up vertical.
On the next tower, I'm going to tie rebar horizontally across the rebar
cage and secure the bolts to it. That way they'll end up correctly
spaced vertically and horizontally. As I said, they're very close, but
we had a problem keeping them in position during the pour.
As and aside, the concrete pumper got "constipated" during the pour.
Boy, I never saw grown men work so fast to try to get it cleared! I
guess the thought of all that concrete in the tube and the hopper was a
bit daunting.
The driver ended up calling in the firm owner and other drivers. I ended
up with four folks from the concrete pump firm doing the pour. My
contractor and his guys just stood and watched.
