Our Floor Lift Spring consists of a resilient decoupler spring, 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 spring mounts or by using higher capacity isolators. Generally, Model SJUM spring mounts are laid out in accordance with submittal drawings provided by our Engineering. 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.
