The railway bridge telescopic device is an important connecting component before the beam end of the railway bridge. It plays an important role in the telescopic and waterproof performance of the bridge end. Its quality and waterproof performance will directly affect the durability of the entire bridge. Due to the high durability requirements of the passenger dedicated line, reliable and durable waterproof telescopic devices must be used between the beam joints to protect the beam body and the bridge substructure.
1. Considering the durability requirements, weather-resistant steel is selected as the material of the section steel. Alloy elements are added to the steel to form a protective layer on the surface of the weather-resistant steel, which improves the weather-resistant performance of the steel.
2. The section steel is processed and formed by an integral hot rolling machine. It has good mechanical properties, accurate cross-sectional dimensions, especially the high dimensional accuracy of the cavity, excellent clamping performance for waterproof rubber strips, and reliable waterproof performance.
3. The steel opening faces upwards, which facilitates the installation and replacement of waterproof rubber strips.
4. Considering that it is difficult to replace waterproof rubber strips to close traffic, the ozone concentration of the rubber ozone aging resistance test was increased from 50pphm to 20050pphm. At the same time, the cross-section of the waterproof rubber strips was increased to increase the service life of the waterproof rubber strips.
5. The waterproof rubber strip adopts a unique box-shaped structure. During the expansion and contraction process, the top surface of the waterproof rubber strip is always flush with the top surface of the steel. It not only meets the expansion and contraction performance, but also plays an automatic ballast discharge function. The gap at the beam end on the curve cannot change. When using box-shaped structural rubber strips, belt-type structural rubber strips are used to meet installation requirements.
6. The railway bridge telescopic device does not bear the direct action of the wheels and does not consider the load-bearing requirements. The structural height of the TSSF telescopic device is only 38mm and can be installed in the bridge deck protective layer. There is no need to install installation notches on the beam body, and the construction is simple and convenient.
