IRC2012 - Masonry Veneer
IRC2012 - Masonry Veneer
(OP)
I'm reviewing the prescriptive masonry requirements of the IRC for the first time and I'm having trouble understanding the language in section R703.7.2.2. It seems to imply that I need to fasten the first rafter with (3) 5/8" x 5" lag screw at every stud. That seems like a lot of screws into the edge of a single stud.
I'd like to assume they meant that each rafter needs a minimum of three lag screws, but only one at each stud. The offending sentence in the code is "...minimum of three 5/8" diameter by 5" lag screws to every wood stud spacing." Any idea what the code writers really meant?

EngMike44,
I do not know what the code writers were thinking,
but in looking at Figure R703.7.2.2, (in the 2006
IRC), this Figure indicates only two fasteners of
the 2" x 6" wood members are fastened to the
vertical (wood) studs.
The language of the code section overrules the
graphics.
If you want an official opinion on this application
/code section, you may want to contact ICC to obtain
one. NOTE: There is a potential that you may get a
different opinion if you call ICC more than once.
(i.e. - different call, different person, different day)
