JORDAHL® Sound Insulation JAI-A1J
Bracket for acoustically decoupling load bearing connections within an elevator shaft.
Application
The JAI system is available in a number of variants for connections within the elevator shaft. The system is typically used to support lift guide rails while reducing the level of noise vibration reaching the lift shaft walls and the surrounding structure.
- New structures: For new structures two adjustable JORDAHL® T-bolts are typically used to connect the JAI bracket to dynamically rated hot rolled JORDAHL® Anchor Channels JTA (ETA-09/0338), which are embedded into the concrete elevator walls.
- Existing structures: The acoustic performance of existing structures may also be up-rated by retro fitting JAI brackets to JORDAHL® Mounting Channels (ETA-15/0386) that are either welded to structural steel or connected to concrete walls using drilled connections that are suitable for transferring dynamic loads.
Description
Elevator Insulation JAI is used to reduce structure borne noise transfer from operating machinery by acoustically decoupling load bearing connections from building structures.
The bracket used with the JAI system comprises of vibration absorbing material that is housed within a steel frame capable of transferring the applied loads back to the structure. It behaves like a mass spring system.
In elevator shafts the system is used for acoustically isolating guide rail and elevator machinery connections by significantly reducing impact sound transmission through elevator shaft walls. This reduces noise levels experienced by occupants of rooms in the vicinity of the elevator shaft when the elevator is operating.”
Features and benefits:
- Significant reduction of sound transmission.
- Increased predictability of acoustic design.
