The impact sound insulation element SINTON® Q decouples stair landings, flights or access balconies from masonry or concrete staircase walls and from the impact noise of footfall. It consists of a load-transmitting round dowel, a vibration-damping wall bearing and a running sleeve with reinforcement cage. Depending on the version (J50 / J120), SINTON® Q is suitable for joint widths of 10-50 mm or 51-120 mm and for transmitting positive (Q1) and also negative shear forces (Q2). The insulation element can be used in in-situ concrete and prefabricated construction. The reinforcement cage of SINTON® Q1 can be inclined by up to +/- 8° so it can be flexibly adapted to the reinforcement of spiral staircases on site. When a fire protection collar is used, SINTON® Q conforms to fire resistance class R 120.
