Stravibase SpringBox

Pre-compressed Spring Bearing

Stravibase SpringBox* bearings are pre-compressed spring bearings for structural isolation of buildings and structures.

Main Benefits

 

  • Can be designed to meet natural frequencies anywhere between 3Hz and 5Hz

  • Easily replaceable

  • Limits deflection of the building during construction

  • Easy to install

  • Lifespan greater than 50 years

  • High lateral stiffness

  • Easily adapted to meet different loads and performance requirements

 

Design Requirements

 

  • Natural frequency requirement

  • Working dead and live loads on each contact point

  • Lateral and turning forces at each support point

  • Contact areas and dimensions

  • Locations of any fixing down bolts

  • Fire protection requirements

  • Maximum likely dynamic forces caused by earthquakes

Case Studies

  • Holliday Wharf Birmingham

    Holliday Wharf

    The listed façade of the Holliday Wharf building located directly above a tunnel is being supported by thirty pre-compressed Stravibase SpringBox bearings.

  • King’s Cross Bridge (exterior)

    King’s Cross Bridge

    Pre-compressed Stravibase SpringBox bearings on top of the columns of the King’s Cross Bridge development protect the building from railway induced vibrations.

  • University of Amsterdam

    University of Amsterdam

    To minimize noise & vibration transmission and reduce extra deflection during construction the steel structure was isolated using Stravibase SpringBox bearings.

  • Ebury Square (exterior)

    Ebury Square

    A staggering 341 Stravibase SpringBox pre-compressed spring bearings limit structure-borne noise at Ebury Square, a high-end residential development in Chelsea.

  • Dalston Junction S5&S6

    Dalston Junction S5&S6

    Part of Dalston Junction S5&S6 needed to be acoustically isolated using Stravibase SpringBox bearings because of its location over a noisy railway turnout.

  • Berckelbosch 5D (architectural rendering)

    Berckelbosch 5D

    Precompressed Stravibase SpringBox bearings and a Stravibase Mat solution protect the housing units against vibrations coming from the nearby factory site.

  • Premier Inn Howard Street (interior)

    Premier Inn Howard Street

    At Premier Inn Howard Street Stravibase SpringBox bearings are used near the railway with a precompression that matched the deflection of the elastomer bearings

  • Park Hyatt Toronto (interior)

    Park Hyatt Toronto

    Stravibase SpringBox bearings installed on top of the steel columns inside the multi-level podium space stop noise and vibrations from reaching the hotel rooms.
