Vibration isolation of railway tracks using the Gelb method.
Functions more effectively than rubber bearings! Depending on the track section, the application of polyurethane pads is also possible.
Buildings adjacent to railways, such as hotels and music facilities, need to reduce the impact of vibrations and solid-borne noise generated during train operations, as they are integrated structures with railway facilities. Coil springs provide a higher vibration isolation effect than anti-vibration rubber. By using floating track slab technology, it is possible to reduce vibrations transmitted from the track to the building by one-tenth (-20dB to -30dB). We propose construction methods tailored to the type of track and site conditions. 【Advantages of the Gelb Method】 ■ Reduced number of installations due to high load-bearing coil springs ■ No need for stoppers due to horizontal rigidity ■ High corrosion resistance allows for outdoor application ■ Embedded slab design reduces installation height ■ Easy height adjustment with shims *For more details, please download the PDF or feel free to contact us.
