Day 3: Rebar and Formwork


I placed more rebar and mesh. Two #4's in the bottom of the lintel, and #4's at the top pf each wall and in every other core. More #10x8" mesh; this time as bottom reinforcement for the 3.5" slab. The bar across the front opening was bent so it will be one continuous piece for some lateral support.

The 2x6 forms for the
foundation slab were modified to make new slab forms.I used some load tie downs to secure the 2x6's and placed scrap pieces at the midpoint of each 2x6 to keep the forms from bowing.

I cut and beveled plywood to support the middle of the slab while it's being placed. The plywood form that covers the middle part is in two pieces that can fit out the "door" once all the concrete sets. All the wood is wedged into place to allow for easy removal and the plywood is covered with plastic to keep it from sticking to the concrete.
