All steel will be 5mm thick, and will be galvanised after fabrication.
Any comments? - I am making the ribs very long as the pier is long, as I want it a metre off the obs floor for comfort, and since the obs will be on short posts it needs to be higher still.
What size plug of concrete do people think I should attach this thing to.... I was going to go about 600x600 by however deep I could get (600-750 or so).... should that be enough??
Ordered the pipe today!  |
Hi,
Have you thought about using maybe 5 or 7 ribs ? instead of only 4 ?
Theoretically it could be that you could get flexure. Look at the pier and apply force in 45° angle. ¿ Could it be that your pier flexes then ?
