The FZA fischer cyclone undercut anchor was used with approximately 660,000 sets to fix the brackets for the ring network and communication systems. With its special undercut technology, the fastener ensures firm connections and maximum safety. After insertion of the anchor, the expansion sleeve is driven over the taper with the corresponding setting tool and the undercut drill hole is filled in a positive-locking manner. The installers installed a further 20,000 FZA anchors for attaching the fire extinguishing systems. The Fischer RG M internal thread anchor was used 12,000 times in combination with the FIS EM injection mortar for fastening the protective doors. The system allows maximum load introduction into cracked concrete and is also approved for seismic applications.
Previously, Fischer had been involved in several projects to expand the Beijing S-Bahn network. These were lines 6, 8, 9, 10, 14, 15, 16, the airport line and also the S1 metro line. The company also supported the construction and expansion of many other railways in Beijing, Shanghai, Guangzhou, Shenzhen, Wuxi, Wuhan, Tianjin, Shenzhen, Ningbo and other cities. With its Chinese subsidiary, fischer supports its customers in the Middle Kingdom throughout the entire construction process with suitable products and services.
