Acoustic wall tie 12.01.01
Add to my wish listNoise and vibration from the traffic, wind, etc. induce vibrations in the building's exterior wall. They are transmitted to the internal structure through the masonry hooks. By replacing typical hooks with acoustic hooks, the mass-spring-mass principle is implemented, reducing considerably the transmission of vibrations to the structure.
Applications:
- Separation of façade-facing walls when outdoor noise is high.
- Temporary lateral façade of semi-detached houses.
- Double wall between apartments.
- Separation of noisy interior rooms.
•The frequency specific to the acoustic hook is about 15 Hz. This means that there is already good acoustic insulation for frequencies from 21 Hz (15Hz x √2), which is below the audible domain.<br/>•Use a flexible insulator for better results.<br/>•Quantity: as specified by the stability engineer (Calculation imposed by Eurocode 6 - NBN EN 1996-1-1 with a minimum 5 p/m² as per the Belgian National Annex)
acoustic block
Dimensions of the acoustic block: 30 x 30 x 25 mm
Material: elastomer based on cork and kevlar fibres
"L" support
Thickness: 3 mm
Material: stainless steel
"U" support
Ø 3 mm
Material: stainless steel
Hook
Ø 4 mm, bent at one end.
The hook length is adapted to the worksite situation.
Material: stainless steel
Minimum gap width
45 mm for L supports.
35 mm for U supports.###
Refer to the technical sheet for more information.
The acoustic block, steel support and hook are delivered separately. Assembly is ensured on the worksite.
- Slide the acoustic block up to the L-shaped support end stop or slide the acoustic block into the U-shaped support.
- Fasten the support with the acoustic block on the wall or on the slab for the L-shaped support or introduce the ends into the mortar joints for the U-shaped support.
- Slide the folded part of the hook into the opening in the acoustic block. The hook is folded into the masonry joint.
- The end of the hook must be visible under the acoustic block.
