Our Floor Lift Mount consists of a resilient decoupler, cast housing, and levelling bolt. The housing incorporates two opposing side lugs for carrying concrete rebar. The levelling bolt is screwed into a threaded opening in order to lift or “jack-up” the concrete slab into final position i.e., floating the floor. Together with Perimeter Isolation Board, poly sheeting, and perimeter sealant, it is a complete floor isolation system.
It permits flexible design of a floating floor. For instance, create any airspace between the isolated slab and the structural deck by changing the length of the levelling bolt. Further, the top of the casting may be extended with an adapter to allow for any thickness of floating concrete slab. High load areas are handled either by adding extra mounts or by using higher capacity isolators. Generally, Model JUM mounts are laid out in accordance with submittal drawings provided by our Engineering department. It offers the designer a simple, adaptable tool for assuring high-quality noise control from the floating concrete floor.
The jack-up system absorbs and insulates noise and Vibration generated from AHU equipment; fan, pumps, power generator.
After installation of the jack-up system, the noise in the adjacent area against the noise of the A.H.U room should have 48dB of transmission loss at 250Hz. (Refer to “Transmission Loss Table”: no glass wool in the 50mm gap) The floating floor must have a 50mm air gap and at least a 100mm-thick steel-concrete slab: mount installation is a follows.
