Bonding wood to steel

Bonding wood to steel

Bonding wood to steel

(OP)
Hi guys

I would like to bond a wood nailing plate to a steel bearer so I can support wood joists. Does anyone know a good adhesive to use and a specification for using it.

Regards

RE: Bonding wood to steel

I've not used glue for this purpose, but, check into Bulldog PL Premium adhesive; I've used it to secure metal plate stiffeners to floor joists/beams.

I typically use small bolts to secure wood nailers to steel beams, or alternatively use powder actuated fasteners...

RE: Bonding wood to steel

I have used "Liquid Nails" for very small applications such as this.  Works well.  You will NEVER get them apart w/o wrecking some wood or steel.

But - I can't "justify" or quantify it.  Maybe google some of the mfgs and find out if you can get some "numbers".  I do know that creep could possibly be a long term problem...

RE: Bonding wood to steel

If this is a drag link, you will never be able to quantify the connection. You would have to use a Nelson Sill Plate Anchor (welded threaded rod with nut and washer), Hilti as mentioned, or something similar.

kf...I'd probably go with a mechanical connection.  Adhesives and their application can be a bit fickle.

Thanks for the advice everyone. I have specified bolts to fix the nailing plate to the bearer. When I was discussing with the builder on-site they (the builder) brought up the possibility of gluing the wood to the steel which is the reason I posted question here.

Thanks

RE: Bonding wood to steel

All adhesive connections used in construction are justified under statistical testing for the exact conditions that they are manufactured. Otherwise they are highly variable for different conditions.

use mechanical fixings
