Going to be casting a large concrete slab floor for a combined garage & car port.. structural calcs done, buildding regs approved ... aprox
6.6m x 8.5m 300mm depp x 450 wide thickened at edges and centre wall, rest is 150mm thick (with a lot of steel)Anybody done any shuttering recently for something this size ...
Assume I use pylwood shuttering with a wood backing frame at top, bottom, edges and presumably at something like 600mm centres.
What thickness shuttering ply ? What size for the support framing .. 50 x50, 75x50?
Guessing that I will use some 45 degree struts to help brace this in place, and probably some steel pins (15mm diam x 900mm) ... driven in at corners and maybe at 2m intervals, to stop form work bowing when the pour is made.
Open to any advice if somebody has done this recently.
