Bracket for acoustically decoupling load bearing connections within an elevator shaft.
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.”
