Staircase step fixture - involves wall ties and brackets only on some step,s with bolts on both sides

摘要

End wall ties, vertical support bars on the other side, with clamping brackets screwed to the steps, and bolt connections between steps, incorporated in a staircase. Between all the steps (24), on both sides, there is a flexurally rigid, height- adjustable bolt connection (26). On the wall side, only below every second, third or fourth step, there is a wall tie (30), independent of the bolts, and screwed in. The system is designed to give a sound insulating effect. Brackets (25) are fitted pref. only on the steps which have no wall ties. Steps may be made of chipboard, or layer-cemented stone steps. Mass-production and installation are simplified.
