More Subfloor framing

This weekend I cut the 2x4x8 to length for my side joists?...maybe rim joists?...the long boards along the sides of the trailer and then secured them to the trailer with these bad boys:

 they are 5 inch galvanized carriage bolts.  The end result looks like this:

Then I screwed in the Simpson Strongtie joist hangers at 16 OC, which I learned means On Center.  I did the 16 OC not because that is building code, although it might be, but because the Roxul Insulation I got comes in 16 inch wide batts and I'm lazy and didn't want to cut them.  I'm not proud to admit it took me longer than it should have to figure out how to measure from the middle of one 2x6 to the middle of the next 2x6.

I didn't get to finish the joists because I ran out of hangers but also because one of the carriage bolts is in the way.  I may have to put one of the joists slight more or less than 16 and then just try to remember the irregularity for later.

Build Site and Subfloor Beginning

Picked up the trailer from Iron Eagle.  Thanks Rob!  I opted for some trailer additions: 22 gauge steel floor pan and some extra fender flashing to help prevent moisture invasion.  Luckily my sister volunteered to let me start my build in her huge garage.  It rained all weekend and the covered build site is fantastic.  Here is the birthplace of Misanthrope Manor:



 then I frosted the whole thing with this stuff:

I used it to prevent thermal bridging.  The trailer is metal and cold and I didn't wan't that temperature leeching into the house.  Also I'm hoping it will be an added moisture barrier between the cold metal and warmer wood.  Here is the end result:

I also bought some 2x6s for the subfloor framing, roxul insulation, a vapor barrier, screws, extra bits, and some simpson strong ties to attach the short floor joists to the longer floor joists, maybe, I'm still working on the vocabulary.  The first small step felt huge.  Next weekend: floor framing.
