Altering the Joist Hanger on landing

[richard7761]

Hi. I need to do an alteration of some type to the joist hangers that are upholding some joist members on the landing of my home.

The house was built in 1957 -ish.

I'm relaying some floorboards and they will not lie flat at some point (where some joint hangers are) and therefore will not match the level of the existing boards.

What would you do? My prefered option would be to replace the topmost nail (the one that is driven in horizontally) with a bolt, and remove the metal overlapping the top of a joist. Except that it might not be easy to make the required hole in the joist in some joist members.

The alternative is to recess the top metal part into a joist.

Please see picture. Thanks.

I need this confirming, but I would have thought the loads are such that the metal strip part does not need to overhang. If the hanger has a bolt fixing.

My problem though would be getting to make a hole to secure the right hand hanger you see in the picture by way of bolt. It would be easy to drill holes for bolts in the others.

P.S. I could drill holes with angled drill chuch gadget.

What size bolt I wonder 6mm, 9mm, 12mm?

You get yourself one of these http://www.ebay.co.uk/itm/MAKITA-BDA351Z-18v-Lithium-ion-Angle-Drill-Driver-Body-/271826427541 or a right angle attachment for a normal drill

I can see me bolting the hanger. Unless someone says no.

I bet two 6mm bolts on either side of a hanger would easily be strong enough. Enabling the overhang to be dispensed with.
