Hardly any joist left!

Maybe extra joists both sides and bolt steel angle bar or flat bar both sides of that cut one

 

more common than you think , plumbers with chainsaws lol

You can double the joists on either side and head that section off

 

I'm probably gonna go with trimming some more of that cut joist off on both ends and double up some 2x10's perpendicular catching the two surrounding joist, spreading the load out.

Edit: Crappy drawing...

 

thats exactly what you should do however in order for the joists either side of the damaged one to take the additional load they should also be doubled , this is usually where it becomes a pain in the ass because they inevitably have plumbing or electrical running through them

 

Luckily one side is already doubled for some reason. This house was built pretty damn well, so I shouldn't have any issues doing what I plan to do. I do agree both joist need to be double, just way too much in the way. Unfortunately this is the area where all the plumbing ties in together. Although I need to take all the copper out anyways in that area.

 

What you are proposing is ultimately better than what is there now , if you can get access to 8 clear feet of the non doubled joist (4' either way of your repair) , subfloor adhesive and screwing a piece of 3/4" plywood to the joist would add some resistance to deflection

 

I can re-route the electrical in that area to accomplish that. It's a spaghetti factory under the ceiling tile anyways and I need to clean it up. So I can get about 10' of doubled joist (5' in either direction of repair roughly).

 

I've used these in the past where plumbers took liberties. Approved for use by code officials.

And these for bigger than allowed holes thru joists.

 

nice

 

It’s been 3 weeks so my footings are fully cured. I’ll frame up both of these walls this week — that’s the mindless part and I already have my headers drying and a stack of lumber ready to roll.

Question for the framing-savvy: in order to remove that center wall I have to add rafter ties on every rafter. My engineer called out a 20 ft 2x4 on each rafter in the lower 1/3 to prevent spread. Not bad at all, but the code book says 8(!!!) 16d nails per side to fasten the tie to the rafter. I feel like 8 would just split a 2x4 no matter how much I stagger. The rafters are 2x6 so there isn’t a ton of lap area:




Any suggestions? Maybe I ask him about timberloks or thru-bolts instead of nails?

Also yes I know I need to re-do the roof on the old side Next spring.

 

ask your engineer how many GRK RSS or GRK R4 or similar structural screws would replace the nails at your connection

Roof looks pretty shallow. I feel like there is plenty of lap area for 8

 

From a completely clueless dude, what about those metal pound-in brackets which come on pre-assembled pieces? Are those adequate to hold tension?



Then you could have zero overlap provided the 2x4 cut angle matched the rafter angle? Is that not OK to do after the fact for specific reason(s)?

 

I havent found a good way to install those

 

4 lb hammer and beat the hell out of it.

 

I smashed it and broke the board

 

Some sort of hydralic vice? I don't see anything purpose-built for that though.

 

those plates are usually pressed in on trusses when they are flat on the assembly table

seriously just nailing or using structural screws on the connection would be easier and a stronger connection

 

Always wanted a 220V welder. Didn’t know I had one behind the stove all along!



yes it is fully tacked on to the terminal haha
