- Product features of special-shaped bridge expansion joints: Low building height. Domestic hot-rolled integrally formed special-shaped steel is as high as possible. The structure is simple and easy to install. It has obvious reliability, comfort and durability. It is suitable for various bridges where the thickness of the bridge deck pavement is greater than or equal to that and the expansion and contraction amount is less than or equal to. It not only facilitates the replacement of expansion joints of old bridges, but also can be used in the construction of new bridges.
Due to improper installation of some expansion joints, the phenomenon of vehicle jumping occurs not only on domestic highway bridges, but also has not yet been solved abroad. Therefore, in order to eliminate steps, prevent vehicle jumping and maintain good road conditions, relevant departments and construction units have adopted many effective measures and methods, which have reduced the disease of vehicle jumping at bridge expansion joints to a great extent. Among them, the installation and construction of bridge expansion joints is an extremely important construction project in highway bridge construction. The quality of installation directly affects the stability and comfort of driving, the service quality and service life of large bridges.
The technical requirements for the middle rubber sealing strip of -type bridge expansion joints: expansion joints using neoprene sealing rubber strips are suitable for areas where the temperature is -℃-+℃. The expansion joint device using natural rubber sealing rubber tape is suitable for areas where the temperature is -℃-+℃.
