China has been investing heavily in the expansion of its infrastructure for many years. This also includes the expansion of the rail network for local transport. Only recently, the National Commission for Development and Reform approved a comprehensive programme for the further development of several metro and subway lines in large cities, including Beijing, Tianjin, Shenzhen and Ningbo.
As a specialist in fastening energy systems, communication systems, fire protection technology, evacuation bridges and wind and hydropower systems, the fischer Group is actively involved in many of these projects with its Chinese national company. For example, fischer has now also been involved in several projects to expand the Beijing S-Bahn (metro) network, namely on lines 6, 8, 9, 10, 14, 15, 16, on the airport line and also on the S1 subway line.The company has previously been involved in the construction and expansion of railways in Beijing, Shanghai, Guangzhou, Shenzhen, Wuxi, Wuhan and other metropolitan cities and has gained a leading position and extensive experience in this area.
One of the most commonly used products is the FZA cyclone undercut anchor from Fischer. In Chinese rail projects, this anchor is primarily used for fastening brackets for overhead power cables, especially brackets for overhead power lines. With its special undercut technology, the anchor ensures positive connections and maximum safety. After it has been inserted into the drill hole, the expansion sleeve is driven over the taper with the FZE Plus setting tool and the undercut drill hole is filled form-fitted.
The FHB II high bond anchor from Fischer is used to anchor the important evacuation bridges in the tunnel tubes, either with the appropriate injection mortar or the quick and easy-to-use mortar cartridges. When setting this bolt, which is available in a short and a long version, the cones of the anchor rod are pulled into the mortar shell, which tensions against the hole wall.
In the case of projects that are underground, many cable routes must be laid, for example electrical cables or ventilation pipes. The fischer SaMontec installation system proves to be versatile in Chinese subway and subway projects. The FUS through-hole system is particularly easy to install, making welding or drilling unnecessary. The design combines bolt, washer, rail nut and spring mechanism in one component.
Fischer has developed a highly flexible installation grid from the individual components of the SaMontec system. In addition, the system meets all fire protection tests for the fire-safe installation of single lines and pipe runs.fischer’s commitment is not limited to selling products and systems, but also offers its Chinese builders a comprehensive service. Each project is supported by a professional team that accompanies customers and partners until the project is completed.
Services include system pre-selection, dimensioning consulting, assistance in meeting contracts, on-site installation guidance and project review to ensure quality and on-time delivery.
