Wall-tie spacing along the wall for RARIS Alu

ScaFix ties RARIS Alu every 4 m in height. Along the wall a tie sits on a standard, so the spacing is always a whole number of bays: for a wall built from one bay length, the table shows how many bays lie between two tied standards and the spacing that gives. Rule: RARIS «Schele de faţadă — Manual de utilizare» p. 13 (ancorare < 20 m: cadre laterale din 4 în 4 m, celelalte din 8 în 8 m în zig-zag). ScaFix is a planning tool, not a structural approval.
