Installation Notes
OCM Mesh Form rule of thumb is to brace Mesh Form like you would a piece of plywood.
The use of rebar, stringbacks, walers, kickers, etc. (location, size and spacing) is similar to that for con- venational forming methods per ACI 347, Guide to Formwork for Concrete.
Notes
- 4”-8” minimum lap between running OCM Mesh Form sheets.
- 2-rib minimum lap between stacked OCM Mesh Form sheets.
- Tie wire around rib and bracing is recommended.
- Bracing where sheets lap is also recommended.
- Attach OCM Mesh Form to bracing with wire, Staples, roofing nails or similar.
- North ribs to make 90 degree turns; ribs face into the concrete pour.
- Cut OCM Mesh Form sheets with a grinder, Cutoff saw, abrasive blade or tin snips.
