Junction function
RC support GS MW U = analogous to S/CH (page 36) with PM1 + concealed fixing.
Critical installation aspects
- Chemical anchors Hilti HVU / Fischer FIS — concrete min. C20/25.
- Rebar scanner before drilling holes.
- PM1 + anchor = concealed fixing system in concrete.
- Mineral wool in 20 mm gap — crucial for thermal bridge.
