So after our exciting trip back from Hilo with 23 skids we started building our skid supported table top forms. Since the skids a little short on height, we will double up the 5/8 plywood which will also add double the strength to the structure. What we did was use two skids on their sides (40 inch high), screwed a piece of 2x4 8 foot board to it to keep them level and straight. We used two 5/8 which makes 1 1/4 inch of material. Our engineer wanted us to use simpson 2x4 holders to support the material in between. They are expensive, at 74 cents a piece. We would need probably 50 pieces or more. Anyway, this way we don't need that kind of support as the material is plenty thick enough to hold up the concrete. The weight of concrete + rebar is about 40kg per sq foot, which is actually not very much. We use the walk on test. When I walk on it and stand, even on on foot and it supports me fine and doesn't bow, then we are good to go for concrete weight.
The most exciting thing will be taking all this out after its cured. Since the skids are disposable, I think we'll just cut them out with a skill saw.
The two plywood material stack on top of each other.
We do add support between the two skids as they are lined up.
So far this much has been completed.
