Modular bridge expansion joint device With the rapid development of China's highway and urban viaduct construction of waterproof tape joints, expansion joints of growing up to get a breakthrough, which requires to have a reasonable structure, large displacement bridge expansion joint device to meet the needs of this development. However, this type of plate rubber expansion joint device, it is difficult to meet the requirements of a large amount of displacement; steel expansion joint device type, and very difficult to achieve watertight seal, and easy to impact on the vehicle, the impact of travel of the vehicle . Therefore, there has been the use of shock-absorbing cushioning performance is good and easy to do the sealing rubber material, bridge expansion joints with high rigidity good combination of strength shaped steel, a large amount of displacement in the case can withstand the load of all types of vehicles Modular bridge expansion sewing device series. Such expansion joint device structure is the same point: the V-shaped cross-section or other cross-sectional shapes of rubber sealing strip (band) d80 joints prices, scarfing in inner edge shaped steel beams and steel beams composed of scalable seal body, shaped steel beam directly bear the load of the vehicle, and can be based on the amount of stretching required, be increased in steel beams and sealing tape (tape) gqf-c80-type expansion joints, bridge expansion joints processing and assembly into a variety of expansion joint device series. Its only difference is that the difference in the form of the transmission mechanism and principle bearing shaped beams and pass on the stretching force. Shaped steel plates have adopted or welded steel with extruded, bridge expansion joints are also rolling Rolling embryo by car or local segments (layer) rolling welding forming. At present, China has achieved a special shaped steel hot-rolled integrally formed localization. The main components shaped steel American Watson (wotson) bridge expansion joint device bridge expansion joints, that edge beam, the beam are made of high-quality corrosion-resistant carbon steel (ie conform to ASTM A-588 standard steel) and manufacturing. Steel Pass CNC turning machine made, pass standard for comparison. Bridge expansion joints rubber seal embedded solid, reliable, good waterproof performance,, are units of modulus 80mm box-shaped and divided the country in two forms based on a bird-shaped rubber seal shape. The basic structure of the bridge expansion joints and design parameters are: 5-23 and list box as shown in Table 5-10; 5-24 listed and bird-shaped as shown in Table 5-11. z80 bridge expansion joints, expansion joints Zhangzhou, Hengshui Hao-Hao factory direct pass by Hengshui Rubber Company.
