C40 Shallow expansion joints bridge expansion joints professional supplier

 C40 bridge expansion joints, expansion joints Shallow professional supplier Example: The GQF-F60 (NR), for example, where the F-type, amount of stretching GQF for the transportation industry standard for 60mm, natural rubber type. Example: The GQF-MZL500 (NR), for example, where MZL type, amount of stretching GQF for the transportation industry standards for 500mm, natural rubber type. Highway bridge expansion joints code representation of the People's Republic of China I produced the transportation industry standard representation consistent .NR and CR, said rubber types: NR, said natural rubber, CR represents neoprene bridge stretching device with plastic material Scope: 1 , chloroprene rubber (CR) of the expansion joint device for temperature is -25- + 60 region 2, the use of natural rubber (NR) in the expansion joint device for temperature -40- + 60 areas for expansion joints to determine the amount For calculating the value of stretching a direct impact on joints specification is selected, if the amount of stretching choose unreasonable, directly affect the results extend the product, should also be considered while selecting between the beams, plates telescopic device the size of the gap amount highway bridge expansion joints, to ensure that the expansion joint device and beams, plates fully anchored at both ends, in order to achieve the best results. Therefore, the choice of expansion joints in the specifications, be sure to leave enough margin to ensure the use of expansion joints and durability. Note: GQF-MZL number of salient features die telescopic device is scalable load-bearing structure and displacement control system apart, when the two forces interfering, clear division of labor, so that not only guarantee the security forces, but also to ensure that the affected even when the force displacement
