Product Description

        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, and the main structural forms are C type, F type, Z type, E type, and M type.
        The GQF-C type bridge expansion joint device is a new type of bridge expansion joint device suitable for the construction of highway bridges in China The GQF-C type bridge expansion device adopts an overall hot-rolled 16Mn special-shaped steel. The comprehensive technical performance and technical indicators of the GQF-C type bridge expansion device have reached or exceeded the advanced level of similar international products. The structural type and special-shaped steel rolling are innovative in China and will become a recommended product for the transportation industry standard The product features of GQF-C type bridge expansion device: low building height, domestically produced hot-rolled integral shaped steel with a height of only 50mm. It is suitable for various bridges with a pavement thickness of 80mm or more and an expansion amount of less than or equal to 80mm. It is convenient for replacing the expansion device of old bridges and can be used for the construction of new bridges
The technical requirements for the rubber sealing strip in the middle of the GQF-C bridge expansion device are as follows: the expansion device using chloroprene rubber (CR) sealing rubber tape is suitable for temperatures between -25 ºC -+60 ºC. The device using natural rubber (NR) sealing rubber tape is suitable for temperatures between -40 ºC -+60 ºC
