Reinforcing floor joists - JLC-Online Forums
2000年11月16日 · Re: Reinforcing floor joists Generally, you can either install a short girder across the two cut joists with support posts, to break down the joist spans, or add scabs of plywood on each joist.

2001年8月10日 · Re: reinforcing floor joists for plumbing Yeah you're right Dick, most Code hole and notch charts should be common knowledge on sites, and definitely any inspector is going to be well versed on the allowances, so figuring the BI wanted additional reinforcement, it makes me think that more is going on in this particular situation, if not, the inspector would have addressed the problem by ...
Reinforcing floor joists - JLC-Online Forums
2004年11月29日 · Re: Reinforcing floor joists As it appears that no architect or designer is involved, I'll take a safe approach.

Once you have determined a path, then install new joists to create new floor framing.

floor joist direction/engineering - JLC-Online Forums
2003年9月15日 · The entire floor diaphragm plays into pinning the top of the basement walls- if it was only in the direction of the floor joists, though, there'd be nothing bracing the other direction.

Joists under granite countertops - JLC-Online Forums
2007年3月30日 · If you properly designed the floor for a tile load (common floor choice for kitchens), the granite will be fine.

Leveling a 100 year old house floor... - JLC Online

Then sister with equal size lumber or 1/4" steel plate. screwed (or bolted, respectively) and glued. Leave jacks on for a couple of months and un-jack gradually. Works well and stiffens the floor also.
