I'm installing a 250 gallon oil tank for the shop furnace. For reasons I'm not gonna get into here I'm mounting it on two right angle frames secured to the foundation wall.
The frames are 3" x 3/16" angle- approximately 16" on the verticals, with the horizontals extending about 37" out from the wall. Theres diagonals running from the bottom of the uprights to the outboard ends of the horizontals.The tank's weight will be centered about 24" out from the wall.
| | | | | Tank | | | | | |___________________________| Wall [ ] [ ] [ ]|______[__]_________________[__]_ [-----------]|______________________________| Horizontals [ Rod ]| | __-- [ ]| | __-- [ ]| | __--- [ ]| | Verticals __--- [ ]| | __--- Diagonals [ ]| | __--- [ ]|_|__--- [ ] [ ]
On one of the frames I can run a bolt through the wall but for the other I had to drill a 3/4" blind hole 8" deep into the foundation.
I just ain't good enough to figure the tension/shear ratios on the rod ( :( ) but I figure 1000 lbs worst case tension on the rod as the tank fully loaded will weigh about 2000 lbs.
Q.- will an 50-50 epoxy/sand mix gooped into the hole & onto the threaded rod hold it in? FWIW the epoxy is West Systems 300 series, really designed for fiberglassing but its what I got handy. The sand is 40 mesh silica from my sandblasting stock.
I'm figuring it will hold O.K. but I'd like some sort of learn-ed reassurance, 250 gallons of oil spilled in the back yard is trouble I
*Don't* need. :/Thanks,
