Kwality Konstrukshun
Hi all
I saw this the other day on site.
The upstairs floor joists are made of 6mm masonite with top and bottom cord made of laminated 70x30mm pine. :eek:
I just had to take a piccy to share with yous lot.

****!!
That looks actively dangerous. The top and bottom chords on the RH joist in the photo are already splitting.
Is it legal?Driver of the Forums

Strewth!
I've seen some dodgy jobs before, but that one's right up (down?) there...
Has the owner seen this "clustermuck"?
Cheers!

I too think that with moisture, even if the web is water proofed, must sag/bend over time.

They are very similar the the hyne beam which uses plywood instead if masonite. It is much stronger than you think. They can span further than regular joists. are much lighter and can be drilled thru in case plumbing or electrical cables are needed. I have never used those masonite types but all floor trusses are engineer designed. The strength lies in the glue and the way the thickness of the material used, not in the pine plates. Most times its just mgp10.
Try and bend a piece of masonite along its narrow end. Virtually impossible. You`d be amazed what is being used in construction.
That splitting is probable caused by the nails that are driven in to secure it to the top-plate.

Crikey, I've heard about them, now there they are, look worse than they sounded..............hmm wonder how they react to deflection or torsional pressure, moving clay soils all that sorta stuff.
