Modular single seam has good durability, comfort, and reliability. Due to its low structural height, it is particularly suitable for the renovation of old bridge expansion devices, and can also be used for the construction of new bridges. Its allowable expansion and contraction amount is 20-120mm, generally C40, C60, C80, D40, D60, D80, D100, D120, ,RG40,RG60,RG80 and the main structural forms are C type, RG type,F type, Z type, E type, and M type.
RG type bridge expansion joint device is a new type of bridge expansion joint device suitable for highway bridge construction in China The RG type bridge expansion device adopts an overall hot-rolled 16Mn special-shaped steel. The comprehensive technical performance and technical indicators of the GQF-RG type bridge expansion device have reached or exceeded the advanced level of similar international products. The structural type and special-shaped steel rolling are both innovative in China and will become a recommended product for the transportation industry standard RG type bridge expansion device product features: low building height, domestically produced hot-rolled integral formed irregular steel with a height of only 50mm. It is suitable for various bridges with bridge deck pavement thickness equal to or greater than 80mm and expansion amount less than or equal to 80mm. It is convenient for replacing old bridge expansion devices and can be used for new bridge construction
The technical requirements for the rubber sealing strip in the middle of the RG type bridge expansion device are as follows: the expansion device using chloroprene rubber (CR) sealing rubber tape is suitable for areas with temperatures between -25 ºC -+60 ºC. The device using natural rubber (NR) sealing rubber tape is suitable for areas with temperatures between -40 ºC -+60 ºC
