Re: stapled sheet metal blocking (wood diaphragm)

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Bob, the stapled sheet metal strips do the blocking. The edges of the sheathing pieces should be "restrained" in alignment (T&G edges or h-shaped edge clips for wood structural panel sheathing) so that the staples don't withdraw if subjected to construction
loads (foot traffic, material buggy wheel loads etc.) over the deck.
