I see what you were asking now. I thought that may be the case, but wasn't sure.
Basically, to form the floor, they frame it up with 2x4's, and support it with Ellis jacks. When they are ready to pour, they will lay plywood down on top of that, and then cover that with plastic. After the pour, after it sets up for 7-10 days, the jacks come down, the supports come down, and the plywood gets taken down to be used on the roof later. In the garage, there are two steel beams that will remain to help hold the concrete up. There aren't any in the storage room (tornado shelter) due to the size and small span. I had never seen this done before, so was pretty interested in it myself.
Here are some pics that should make it clear. The first 3 are the garage, the other 2 are the storage room. Kinda hard to get good pics. Feel free to ask any questions. If I don't know from my discussion with the contractor, I can ask and find out.
Interesting build/construction method.....this is going to be interesting:thumbsup: Consider embedding your pictures so us lazy guys don't have to click on them to open them. If you have them on Photobucket (or something similar) & already re-sized to medium, click on "URL" instead of "Computer" and paste 'em there...like this:
If sized to "Medium", this picture would be much larger....I can make it smaller but not bigger so you must have re-sized it pretty small.
The basement floor was around 5". The suspended floors will be a bit thicker just for more support since they are suspended. I don't think they use wire mesh, only re-rods. I know the basement floor did not have mesh, not sure on the upper floors.
I will see what I can do on the pics if you guys would rather see them inline. The files are automatically uploaded from my phone to OneDrive, so I just post from there. It was resizing to 'medium', but I changed it to 'large'. I will see if I can post directly from there instead of attaching them to the post. If not, I will just set up a photobucket account.
