Modular bridge expansion joint unit with the rapid development of China's highway construction and urban viaduct, the bridge grew up to get a breakthrough technology, which requires reasonable to have a structure, a large displacement of the bridge expansion joint device to adapt This development needs. However, this type of expansion joint plate rubber products unit, it is difficult to meet the requirements of a large amount of displacement; steel type of expansion joint device, but also difficult to achieve sealed impermeable, and easy to impact on the vehicle, the impact of travel of the vehicle . Therefore, there has been a good use of shock-absorbing cushioning performance and easy to do the sealing rubber material, with high strength and good rigidity shaped steel combination, in the case of a large displacement of the vehicle load can withstand all types Modular bridge expansion joint device series . Such expansion joint device bridge expansion joints, its structure is the same point: the V-shaped cross-section or other cross-sectional shapes of rubber sealing strip (tape) fd80 bridge expansion joints, scarfing edge in the composition of the beam can be shaped steel and steel beams retractable seal, shaped steel beams directly under vehicle loads, and can be based on the amount of bridge expansion joints gqf requirements arbitrarily increase in steel beams and sealing tape (tape), processing and assembly into a variety of expansion joint device series . Its only difference is that the difference between the transmission mechanism in the form and principles of load-bearing shaped steel beams stretching force and passed on. Shaped steel has welded by steel or steel bridge expansion joints d60, has extrusion, but also by the car rolled steel rolling embryo forming or partial segments (layer) rolled welded forming. At present, China has achieved a special shaped hot-rolled steel integrally formed localization. Series of specifications and design parameters of J-75-type expansion joint device series telescopic amount in the range of 0 ~ 1040mm. Its installation is reserved slot size, model and design parameters, listed as shown in Figure 5-6 and Table 5-2.
