Browse Forums Building Standards; Getting It Right! 1 Jul 29, 2016 8:00 pm Quick question - can I use 'interior' timber for work that will sit under roof trusses and roofing tin? It will be totally enclosed and out of the elements. (It is going to be tek screwed to the top of my shipping containers to attach the truss bearers to.) Or does it have to be external grade? There are no specs on my engineering plans or from the truss manufacturers. Re: roofing timber question 2Jul 30, 2016 8:28 am Structural timber is graded in the notes on REAL engineering plans, reference AS codes,etc,etc.. More info required?

Re: roofing timber question 5Jul 31, 2016 4:23 pm Sorry - not much info to go on! When ordering my roof trusses I've discovered that I need to raise the edge of my containers a little to account for the slight upward bowing of the container roofs. So I am attaching a single piece piece of 90x45 with tek screws along the perimeters of the containers (as was done in this photo from a Melbourne container house) Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ The truss bearers can then sit on these. Where I buy my timber (Big Green Shed) I was directed to the MGP10 blue structural pine for internal framing. I was wondering if this was suitable as technically being under the roofing and protected from the elements it is similar to internal framing conditions. (The other 'outside' pine was H3 treated whereas the blue is treated for termites.) This doesn't appear on my engineering plans as it was an unforeseen situation and my engineers in the past have taken up to 4 weeks to answer some of my questions. So I thought it would be quicker to get an answer here!! Re: roofing timber question 6Jul 31, 2016 10:06 pm yes that would be fine to use that ,I would bolt through using min M10 nuts and bolts or even M12 but would double check with your engineer as this will depend on uplift load width and what wind classification area you are in. Re: roofing timber question 7Aug 01, 2016 8:47 am Judging from the Photo if the truss roof is to have an opening/gap between the container and bottom chord ie for ventilation then this wind load combination should be checked by the engineer.

Hi StructuralBIMGuy - my trusses will not have the gap as in the photo (this is the roof of a Melbourne container house which I used just to illustrate the timber plate I was referring to), they will be tied down to the containers per the engineers specs. I plan on installing an undercover walkway (awning ??) from my carport to the back door as shown in sketch. I will be using Boxspan Beams and have no concerns regarding… 0 88 Engineering timber is certainly a less fuss option, times cheaper to supply and install and better withstands humidity. 1 15884 Thanks Simon, I guess I'm no concerned with the volume of the noise rather that dead and hollow sound and feel that is associated with floating floors. But I'm not sure… 3 6110 |
