Wall-tie spacing along the wall for RUBO RK

ScaFix ties RUBO RK 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: Rozp. MI 6.02.2003 §115 (Dz.U. 47/401), via Warbud BHP standard 2.2 p. 4: kotwy co drugie pole i co drugą kondygnację, przesunięte o jedno pole. ScaFix is a planning tool, not a structural approval.
