Hello,
I came across a post here in which a fellow received some good advice with this type of construction. I am looking for any comments or advice as I am not a professional builder rather "acting as my own general contractor".
I am building a home in Central Oklahoma and am interested in a 4" suspended concrete floor on top of a walk-out basement. My reasons for this are as follows:
1. Allows a quick dry in of the basement for interim living / storage while saving for the materials needed to complete formal dry in.
2. Protection from tornados / weather.
3. Sound deadening / insulative characteristics.
Here is my proposed design:
1. Basement dimensions are 30' x 40'. A 39lb/ft Wide flange beam splits the long dimension supported by posts equally spaced and secured into the basement wall. This reduces the 30' span to 15'.
2. Joists constructed from 8" C purlin are welded into receiver channel and are spaced every 12". The receiver channel / Joist ends bear (Welded to 1/4 in plate steel) on top of the basement walls and the top of the wide flange beam. Joists are tied together with flat strap to prevent twist.
3. Q-paneling (14 gage waffle panel) is installed over the joists. Knock outs are installed for electrical / water etc.
4. 2x4 Base angle (14 Gage Angle shape) is welded to the perimiters in order to form or hold the concrete in place.
5. Half inch rebar is placed on 12" centers.
6. 4" of concrete will be poured on top.
Any analysis, concerns, critiques or comments on this design is much appreciated.
Best Regards,
Pete
