Temporary wall support question...

17 years ago

I will be removing 23Â of brick/block exterior wall, replacing it with a wood framed LB wall (to allow various access points to new addition). Inside the house, IÂve installed a temporary wall to take the load of the exterior wall once removed. The ÂloadÂ in this case is an attic space and roofÂnot second story livable space. The temporary wall consists of a double 2x6 header, and jack post every 4Â. The temporary wall sits 1.5Â from interior of existing LB wall, and in parallel.

The existing situation is this - the ceiling joist and rafter meet on top of the block/brick wall, are nailed together and toe-nailed into the top plate (normal stuff). Both, ceiling joist and rafter bear downward load on the exterior block/brick wall at that meeting point (normal stuff). Once the LB wall is removed, downward load shifts 1.5Â back to my temporary wall. Along with that, the nailed ceiling-joist/rafter connection has lost its support (block/brick wall) and the nailed connection itself becomes stressed/loaded by the rafters and everything they support (sheathing and roofing).

Question: Does additional temporary support need to extend from top of the temporary wall (top of double 2x6) through the attic, and to the rafters so that the nailed ceiling joist/rafter connection doesnÂt take load that it cannot handle? If so, how is this typically done...just stick framed between temporary header and rafters?

How long are you going to be on the temporary supports?

If it is only a short time it should be fine.
Things to worry about are new loads on the roof (like snow).

A bigger concern is what is under the temporary wall for support.

The roof will transfer some load to the end of the now cantilevered ceiling joists.

The temporary wall could be there for a couple months. I'm thinking it wouldn't hurt to run a 2x support from ceiling joist to rafter directly above the temporary wall - Most likely for every other joist/rafter combo.

"what is under the temporary wall for support".
I built it on a double 2x bottom plate, which is sitting on subfloor over 2x8 floor joists. Below the floor joists is unfinished basement, where I've got another temporary wall going to the slab. I do believe I am good to go on both levels of temporary support...it's just that ceiling joist to rafter support that I wasn't quite certain of.

I, of course, could not have let myself do anything but play it safe and install the added supports, but figured I'd ask and see what other info folks might have.

We built a couple dead mans for support. Made of a 4 x 4 post with plywood on top. One lived in front of my computer desk for over a month.
