Fastening a steel pipe to a wood pile cap

Fastening a steel pipe to a wood pile cap

Fastening a steel pipe to a wood pile cap

(OP)
What fastening methods could be used to secure a timber pile cap to a 10.75" diameter 3/8" wall steel pipe? The application is the replacement of creosote wood pilings with steel pilings. Since NOAA will not allow timber pilings, I must use steel or concrete. Appreciate any suggestions.

RE: Fastening a steel pipe to a wood pile cap

Not sure I understand

You have creosoted pilings in place for a dock and they ahve detreiotated to where they need to be replaced?  You have to use steel or concrete to replace them?  

At the top of the new steel or concrete piling you want to have an untreated timber cap?   You want methods to fasten the timber on top of the steel or concrete?

How close is any of this?

Yes but the cap on top of the steel or concrete piling will be the old treated timber cap. It is still in good shape. So long as I am not replacing it with new treated then Corp of Engineers and NOAA do not care. If I do a rebuild instead of a repair then the permitting process will be very long.
Thanks

RE: Fastening a steel pipe to a wood pile cap

Can you weld clips/tabs to the pile that can then be bolted to the cap?  Bolting is the only commonly practiced way I have seen to connect wood to steel for structural purposes.

(OP)
Thanks, I'll do that if I use steel. How would I fasten the pile cap to a concrete pile?

RE: Fastening a steel pipe to a wood pile cap

Can you drill or bore thru the top of the wood cap and into the concrete pile and secure with structural bolts using lead anchors?

RE: Fastening a steel pipe to a wood pile cap

You could cast steel members into the concrete with holes to fasten to, or drill the concrete and use wedge anchors (or similar mechanical fasteners) or adhesive anchors.

RE: Fastening a steel pipe to a wood pile cap

I like the ideal of casting the fastener into the concrete pile and then bolting. This may be more expensive then drilling through the pile but it will not ruin the prestress members (I think that is what they are called) anyway thanks to everyone for the ideals.
