In the wheat growing areas of Eastern Oregon there are many old graineries that appear to be constructed from 2x4s laid flat and stacked up for the walls.
I have always liked their appearance and would like to construct a garage using this technique. My question is in regard to figuring a nailing schedule for the courses of 2x4s. Any suggestions on the size and spacing of nails to hold each layer together, or how I should figure it? Any suggestion for caulking between the layers that will last for a number of decades? (I thought about doing splines, but I think that I am not that ambitious…)
(Yeah, I know, it will take a bit more material than traditional framing, but hopefully the 3.5″ walls will slow the vandals down a little bit…)
thanks, Casey

Well, when one of the old feed mills was rebuilt a couple of years ago, a combination of two methods of attatchment was used.
The 2 x 4's were stacked about 9 or ten deep. Then a guy came along with a long bore and drilled through 'em all so something like allthread could be drifted. Each layer was offset in length so to form something like a finger joint to mate with the next section. Never was a stack made so the ends of each 2 x 4 lined up with another.
These sections were then nailed together using 20d (and larger) spikes. Started at a corner and went right around the building. Stands over 100' tall with large equipment up there.
For a garage, I may suggest long rebar set in the footings. Predrill the 2 x 4's so they fit onto the rebar and cap with washers and nut. whaddya think?
