Step 1 taking safety precautions.
Steel reinforcing rods rebar to stakes set about four inches from the perimeter of the forms.
Step 2 deciding on the size.
The air gap in the tubes will act a insulation since heat travel through air will be less.
Step 4 coat with primer.
Make sure you wear all.
Then a concrete mixture is poured spread through the framework and reinforced with steel bars which serve as a kind of skeleton for the cured concrete.
Install a row of concrete blocks on their faces with the open ends facing towards the sides.
The joists are basically to provide a foundation for the concrete blocks.
The cap beam evenly distributes the load of the roof slab to the piles below.
The steel bar joists are l shaped so the blocks have a flange to sit on.
Use a single piece wherever you can and make sure it is centered over the seam when you put it down.
Tie two bands of 1 2 in.
Step 3 placing the steel joists.
Understand the gravity of the project and take the necessary safety precautions.
