Drill a 3 8 hole through the floor plate with a standard wood bit then switch to a hammer drill with a 3 8 masonry bit to drill at least a couple inches into the concrete.
Reinforcing half wall on concrete.
The mesh should be positioned in the top half of the thickness slightly above the middle of the concrete slab.
The reinforcing bars should be as long as possible yet still be able to weave between the horizontal joint reinforcement typically installed at 16 inches on center vertically.
Where rebar rods join they must overlap and be tied together with tie wire.
Rebar short for reinforcing bar is mild steel rod that comes in various thickness.
The use of upside down joist hangers is reommended to add tensioning strength to the blocking.
This gives some space for the debris that accumulates at the bottom.
2 5 clear to strength steel 5 12 rather than the designed 5 10 bending strength of the section has been reduced by about 16.
It requires using 1 2 to 5 8 threaded rod from the top wall plate down to blocking in the structural floor below.
Rod 1 2 inch or 5 8 inch rod through the wall s top plate and all the way down.
Rebar is usually manufactured with deformations i e.
Because there are more horizontal mortar joints in a wall constructed using half high units there is slightly less concrete web area in the wall overall.
Reinforced concrete wall is classified as.
Reinforced concrete wall is designed as a compression member.
Plain concrete wall when reinforcement 0 4.
Reinforced concrete wall is used in case where beam is not provided and load from the slab is heavy or when the masonry wall thickness is restricted.
The threaded rod method works great when reinforcing a half wall but is hard to do and super time consuming.
Using threaded rod to stiffen the half wall.
The bars must be lapped and positioned in the center of the core.
Strength of reinforced concrete sections amount of rebar a s the project calls for 5 10 and 5 12 are used.
Although this theoretically reduces the wall weight in practice the wall weights of walls constructed using half high units are within 1 psf 0 05 kpa of those for full height units see ref.
This must remain in place as it is needed to tie the wall together to control shrinkage.
