VIBRAX®STAIR stair support I-shaped

VIBRAX-STAIR stair bearings – structure-borne sound insulation for concrete and in-situ concrete stairs

VIBRAX-STAIR stair bearings are used for the structure-borne sound insulation of staircases made of in-situ concrete and precast concrete elements. The system offers a ready-to-install, technically optimised solution for all standard support configurations and stair weights. The supports transfer horizontal and vertical forces directly into the landing, whilst effectively maintaining acoustic decoupling in the area of the supports.

Product description

VIBRAX-STAIR stair bearings are used for the structure-borne sound insulation of staircases made of in-situ concrete and precast concrete elements. The system offers a ready-to-install, technically optimised solution for all standard support configurations and stair weights. The bearings transfer horizontal and vertical forces precisely into the landing, whilst effectively maintaining acoustic decoupling in the area of the supports.

The system includes, among other things, the sound-insulating locking pin VIBRAX-STAIRTOP SL, as well as the permanently elastic foams LASTO-STRIP PE and VIBRAX-ROPE round profiles, which further support the function. Impact sound – a specific form of structure-borne sound – can lead to disruptive noise transmission in stairwells of residential and commercial buildings. VIBRAX-STAIR creates an impact sound-insulating layer between the stair tread and the landing, which significantly minimises this unwanted sound transmission.

With the insulation core used, an insulation effect of up to 99% or an impact sound improvement index of up to 40 dB can be achieved at an excitation frequency of 100 Hz (in accordance with SIA 181:2006).
