Pockets / slots on concrete shearwall for slab reinforcing bar splice
Pockets / slots on concrete shearwall for slab reinforcing bar splice
(OP)
Hi All,
When casting concrete shear walls by means of climbing shutter if the wall is to be cast through multiple floor slabs, the connection with the slab could be achieved by means of slots provided for slab reinforcement to pass through. What good methods could one employ to avoid air-entrapment and consolidation problems within the slots when casting the slab?
How effective is it forming say 20’ overcast at sloping bird-mouth above the slots?
Thanks.

Difficult to describe, I'll see if I can locate a detail.

I'm not quite sure how the Z shaped bar you mention work, but if it requires field re-bending like a pull-out bar shown on the attached detail its won't be desirable with larger diameter reinforcing bars as it usually causes them to kink.
