A vertical spiral riser is slipping and crushing fittings
A vertical spiral riser needs structural load support. Stop stacking weight on slip joints or light wall straps.
Stop if
- The vertical spiral riser at [shaft/location] is slipping and crushing the lower fittings. I stopped stacking sections. Do you want structural riser clamps/angles installed at the slab line?
Watch out
- Do not support a heavy vertical spiral riser from light wall straps or slip joints.
Check
- Check whether the riser is sliding at joints.
- Inspect bottom elbows/fittings for crushing.
- Identify actual structural support points.
- Do not rely on light-gauge studs for riser weight.
- Coordinate riser clamps/angles with foreman/detailer.
Steps
