STAIRCASES AND LANDINGS ACOUSTICS

People create noise by walking which can be transmitted to the neighboring rooms as structure-borne noise. One particularly frequent but easy to prevent disturbance is the noise from the staircases and landings. TVS provides the bery best staircases and landings acoustics products.

The transmission takes place through the bordering walls and floors. To protect the residents from unnecessary noise, either the disturbance or the transmission must be reduced. A reduction of the transmission is technically possible through elastic separation of the flights and the landings. The impact noise generation can be reduced, for instance, through the use of soft-floor covering. However, the use is problematic for a variety of reasons.

Material

Sylomer® is a high-quality technical material for the elastic separation of stair flights and landings which easily allows for various designs. The in-creased requirements as per DIN 4109 Addendum 2 are already safely fulfilled under typical installation conditions with a 12 mm bearing thickness. The bearing can be laid in bearing strips or at individual bearing points. The volume required for deformation is provided “within” the microcellular structure of the material.

Sylomer® bearings therefore remain effective without limitations even if they are installed completely enclosed. Areas not occupied by the bearings can be filled up with soft, non-supporting material. This significantly reduces the risk of sound bridges.

The dimensioning of the bearing is determined in accordance with the bearing dimensions, the dead weight of the structure and the expected traffic load. A wide-ranging type selection ensures that the bearing can be adapted optimally to the specified bearing surfaces and loads. Short-term load peaks are easily accepted by Sylomer®.

Bearings of Sylomer® have proven themselves for decades. With correct dimensioning, no dynamic stiffening of the bearing takes place. The effectiveness of the measure is therefore maintained even after decades.

Bearing For Stairs Flights And Landings

The bearings are situated on the upper and lower supports of the stair flight. Typically, Sylomer® bearings strips with a thickness of 12 mm are used, installed across the entire width of the flight.

Bearings for landings can be laid as continuous bearing strips or as individual bearing points. The large range of permissible loads and the availability of Sylomer® bearings delivered in almost any dimensions, mean that the bearings can be optimally adapted to the existing conditions. The bearing thickness is typically 12 mm.

Installation

For installation, the bearing strips are simply laid onto the prepared surface and bonded to the substrate in a point-wise manner, as required.

The bearing surfaces must be level and free of sharp-edged elevations or depressions. To prevent sound bridges, areas not filled up by the bearing should be packed with a soft filler material.

The measure is only effective if the stair flight or landing is completely elastically separated from the bordering structures. All joints must also be permanently elastically separated. The side separation is typically achieved using an elastic strip, such as Sylomer® SR 28-12. The strips should be installed such that sound bridges are avoided even during the construction phase.

The stair flights and landings can be created with onsite-mixed concrete or prefabricated concrete slabs may be used.
