AI Thread Summary
A user is seeking advice on anchoring a timber ledger to a concrete pool using 10mm stainless-steel threaded rods, with concerns about drilling depth due to reinforcing bars. The adhesive requires a 90mm embedment, but the engineer limits drilling to 70mm. The user questions whether to adjust the spacing of the rods to maintain strength or if the situation is more complex. Suggestions include using bar locator probes to find safe drilling spots. The discussion emphasizes the importance of adhering to engineering specifications while ensuring structural integrity.

Hi All,
my first post on this fantastic forum.

I am attaching a timber ledger to a concrete pool with 10mm stainless-steel threaded rods at 900mm centres. I am using a polyester adhesive made by ramset to anchor the rods into the concrete. The adhesive instructions call for the rod to be embedded in a 90mm deep hole. However, the engineer who designed the pool will only allow me to drill 70mm deep because the reinforcing bars are embedded 75mm from the outside of the shell.

My question is: do I simply reduce the distance between the threaded rods by the ratio 70/90 (i.e. 700mm centres) to achieve the same overall strength, or is it more complicated than that?

Appreciate any advice.

Regards,
Jack

You can hire bar locater probes to find the spaces between the bars and drill deeper there.

Look up 'concrete cover meter' in you local YP.
 
thanks Studiot, I'll look into it.

Thread 'I need a concave mirror with a focal length length of 150 feet'

I need to cut down a 3 year old dead tree from top down so tree causes no damage with small pieces falling. I need a mirror with a focal length of 150 ft. 12" diameter to 36" diameter will work good but I can't think of any easy way to build it. Nothing like this for sale on Ebay. I have a 30" Fresnel lens that I use to burn stumps it works great. Tree service wants $2000.

Thread 'Questions about the Tesla turbine'

Hi all, i have some questions about the tesla turbine: is a tesla turbine more efficient than a steam engine or a stirling engine ? about the discs of the tesla turbine warping because of the high speed rotations; does running the engine on a lower speed solve that or will the discs warp anyway after time ? what is the difference in efficiency between the tesla turbine running at high speed and running it at a lower speed ( as fast as possible but low enough to not warp de discs) and: i...
