Roof truss building plans?
Question:I need building plans and a material list for a 32 foot span truss 4/12 pitch with 2x6 chords and 2x4 bracing with no overhang. Want to build them myself and place on 3 or four foot centers.
Answers:
You'll never pass the 48" c/c issue. any code I've seen does NOT permit it. [worked on a crew that did one large motel job on 48" c/c many years ago because the building offical missed it, he made a big stink until he saw he made an error in approving them at 48"]
You might get by with 32" c/c with 5/8" or 3/4" decking and a couple of H clips. And you well need to have a truss company design and stamp your trusses even if you DIY.
Call a truss company or retailer that sells trusses.
They will need to know where you live and the exact centers they will be placed on.
They can get you an engineers drawing of the trusses with load specs but there will usually be a disclaimer on the drawing stating they will not be responsible if they don't build them.
Having worked for a truss manufacturer, you might be able to convince one to give you a drawing, but I doubt it. Truss manufacturers use a huge press to apply the plates they use to connect the various chords and webs. They won't be readily able to engineer one that is hand nailed. So, you would end up having to call an engineer, and that costs a bunch of money.
Why don't you just purchase the trusses? Call your local lumberyard (not Lowes or Menards or Home Depot or the other big box retailers) and ask them to get you a quote for these trusses. The only other questions you will need to answer for them will be what type of roof and ceiling materials are to be used in your project. I'm guessing your trusses will cost less than $100.00 each.
building inspection wont accept home built trusses without an engineers stamp on a set of plans stating loads and calcs. trusses are usually cheaper when they are manufactured. the truss company supplys the engineers calcs with the order.
