Industry knowledge
Railway fish bolts are fasteners used to connect rails and fix sleepers to rails. They are used to strengthen the structure and ensure the stability of the railway through the combination of bolts and metal plates.
It is mainly used for the fixed connection between rails and sleepers. The fish plate (metal plate-shaped part) is used to tightly connect the rail joints to prevent the rails from shifting or vibrating.
Application scenarios of fish bolts
1. Track connection
In the laying of railway tracks, fish bolts are often used to connect sleepers and rails. It can ensure the stability of the track, reduce track deviation or shaking, and maintain the smoothness of train travel. In the track engineering of Hong Kong Railway, fish bolts are used in conjunction with rail clamps to ensure that the rails are firmly fixed on the sleepers.
2. Bridge structure
Hong Kong has a complex terrain, and many railway lines pass through bridges and tunnels. In bridge structures, fish bolts are used to connect key components such as bridge decks, brackets, and supports. Its tensile strength and corrosion resistance ensure the safety and stability of the bridge structure and provide a solid foundation for the train.
3. Steel structure support
In some railway maintenance or expansion projects, fish bolts are also used in steel structure support systems. These bolts connect steel beams, brackets and guardrails to ensure the integrity and seismic resistance of the structure.
4. Other mechanical connections
In addition to the above main scenarios, fish bolts are also used in the installation of signal equipment, lighting facilities and other railway ancillary equipment to ensure the stable connection of various mechanical parts.
Each rail bolt is strictly tested and processed with multiple processes, without missing any details. From thread accuracy to surface treatment, GNEE RAIL manufactures products with a meticulous attitude to ensure that both service life and installation adaptability meet the dual standards.
