Creak from Pozi joist in hanger

[crispy_wafer]

Hi All,

 

Been working in the bathroom upstairs and have discovered a creak in my floor.  The floor build up is 22mm egger on 304*122mm pozi joists, glued and ring shank nailed. The creak is coming from either close to or right at the end of the joist where it sits into the hanger.  The hanger sits onto a steel.

 

I can access from below, and if I pull/push the joist with my hand from below I can make the joist creak on command!  The bit of flooring above is fitted tight to the steel, every other bit of flooring the builder left about an inch gap.

 

I'll pop up some photos tonight.  But would love some help with this.

It’s more likely the floor against the steel Can you trim it back with a multi tool

yes, I can do, and will do this.  

 

Phone died, but boshing the hanger with a hammer encouraged the flanges back behind and against the timber stopping the creak.  before the flange was tight on one side but a few mm out on the other.

Just to close this, the pozi's are installed into hangers onto a steel, I detected a small amount of movement in the joist when pushing and pulling the corner of the bottom chord in the location circled on the photo!  I have since glued and screwed lengths of 5*2 as bracing against its neighbouring joist to try and mitigate against any future lateral movement.
