Are my notches big enough?

[Marcus Vaughan]

Found this beauty today, a 5 inch notch in a 6 inch joist.

It wasn’t me!

I felt sorry for the homeowner - and remember finding the exact same thing under my bathroom floor years ago.

A 5 inch notch in a 6 inch joist. Perfect for a 4 inch pipe.

Is it an open span below, or have they been lucky and its all being propped up by a wall?

Either that or the lathe is 6 inches thick

lath baddegg. lath. a lathe is for turning wood.

 

[Baddegg]

Ha ha yep a lathe wouldn’t help much there would it!

 

[richy3333]

Wow that's nuts. Even around my way they'd not do that!

Seen three 6" joists reduced to 2" across 800mm to allow a shower tray to sit flush with the tiled floor once. The kitchen ceiling below had a noticeable dip in it.
Plonkers !

Ok chaps and chappesses. How would you fix the problem without replacing the joist? I’d look at cutting a new block of wood to fill the notch and then fitting some sort of bracing plates that overlap some distance either side of the notch. Would even look at Acroing up the joist slightly prior to securing if there was any sag.

Yes, I agree..."sistering" would be the way to go to fix that...jack up, double the joists either side, and run steel plates either side with bolts through at about 50mm apart.

You must have sheds loads of well seasoned oak from all the ships you've acquired over the years. Perfect for this task

Indeed Archy! Well-seasoned is the way to go...
but that's the thing...new wood is so crap, fast grown, weak and pathetic.

 

[DefyG]

Odd, as when comparing with the notch to the right, it looks quite new and fresh as if recently just been done!

you don't need timber if fixing steel pates, so your brigantine is safe...... for now.

nah.. you lot are far to over kill, you just need a can of expanding foam, a big hammer to make lots of noise and then feed the home owner with some -------- so he thinks he's getting a quality job done for twenty quid.
