I have an interesting question about a practice which i have seen in a carlise home. Apon inspectiong I found that they do not use a truss plate on the external walls. They simply made the external wall taller (or the internal walls shorter) to allow for the moment in trusses. What concerns me is that there is only a 35mm top plate holding up the roof of cement tiles. Is this legal. I was just wondering for my own benifit. Re: Truss Plate Is this required 2Dec 10, 2008 3:37 pm The 'truss plate' is not a requirement as such. It is merely to enable all the wall frames (studs) to be cut to the same length
As long as the load is within 1.5 times the thickness of the top plate from the stud then the top plate is not considered as structural.

Re: Truss Plate Is this required 3Jan 20, 2009 2:50 pm Had same issue with Henley home i thought they were the only ones to tight not to double top plate frames we had around 15 points were they wernt within 1.5 times stud thickness and just added support between stud spoke with inspector and is ok but is bare minmum would prefer double top plate. Re: Truss Plate Is this required 5Jun 29, 2009 2:41 pm This is such a cheap building practice. If the trusses aren't spaced practically on the studs then the maximum span is about 5m, thats span not roof load width, even less if the plates are trenched. I dont see how they would be spaced on the studs assuming 450 stud centers and 600mm truss centers. Re: Truss Plate Is this required 11Jul 12, 2009 5:35 pm And having worked with some of these gangs in my early years they don't get paid enough to care too much whether it is within code or not, and yes this is why we have inspections, but even they miss items Re: Truss Plate Is this required 12Jul 25, 2009 10:56 am Hi all I think this was one of my old questions and Im still a bit concerned. Ive looked at heaps of project homes since getting great info from you guys and I see more & more single top plates. The guys putting up the frames just say its cheaper. Im with a project builder and the more I find out how they build them I wish I did not ask. Ive also got a single top plate but its 45mm MGP10 I had to write it into my contract to get it. Also 450mm centres external of 90 x 45mm. It was going to be 35mm @ 600 centers. Just as well Ive got a color bond roof. lol If I may ask, the bit about 51mm does that refer to the trust must be with in 51mm of a stud under it? Also I see less window jam studs. Even on wider windows. Anyway to save a meter or 2 of timber they will find it.

Re: Truss Plate Is this required 13Jul 27, 2009 12:11 pm That 90x45 with 450 centers sounds much better even if it is just one top plate. The 51mm was referring that the truss or rafter must be within 51mm of the stud. But because your using a 90x45 top plate you won't need to stick to that rule of having the trusses sitting over the stud unless the roof load limit is exceeded for the 90x45 plate. Good on you for checking this out though, so many home owners are oblivious to the structural skimping that goes on with there jobs as they worry to much about the size of skirting etc. It's hard to comment as the photos area bit dark ( you might need a new 15 - just got one and wow ) Jokes aside, I can see one member that is cracked.
