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 GQF-Z40 bridge expansion joints, high rigidity and strength of a good combination of shaped steel bridge expansion joints, in the case of a large amount of displacement can withstand a variety of vehicle loads Type Modular bridge expansion joint device series. Such expansion joint device GQF-C40 bridge expansion joints, its structure is the same point: the V-shaped cross-section or other cross-sectional shapes of rubber sealing strip (tape), scarfing scalable shaped edge on the composition of the steel beams and the steel beams The seal, shaped steel beams directly under vehicle loads, and can be based on the amount of stretching required arbitrarily increase in steel beams and sealing tape (tape), processing and assembly into a variety of expansion joint device products. 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 steel welded by steel or with 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. According to the principle structure of TCS-filled thermoplastic elastomer bridge joints, and must strictly adhere to all the major aspects of construction, should generally use embedded squeeze good stiff presentation of processed gravel, its specifications main floor for 20-40mm, the surface layer To 5-10mm, and requested its value is not more than 30% crushed, flattened and elongated stone content should be less than 15% -20%, and must use special equipment for heating, the heating temperature should be controlled at around 100-150, special The RS composite rubber, the heating temperature in the 190-210, short of 230, the temperature shall not exceed 2h, should pay attention to in the wind more than 级 3 GQF-F60 bridge expansion joints, the temperature is below 10 under the weather, not construction, For different amount of stretching that, according to the material per meter of different slot sizes, TCS bridge joints filled thermoplastic elastomer material, in fact, the construction process can be roughly in accordance with the grooving, clean tank, drying notch, coated adhesive agents, gravel heating, paving gravel, pouring RS line with rubber, leveling is complete. For ease of calculation analysis and practical application, accustomed to the temperature bridge structure changes due to the above causes is subdivided into two parts. Linear and nonlinear temperature changes temperature changes in the design of the bridge structure, should consider the role of temperature, which accounts for structural linear expansion caused by temperature changes of the bridge structure of the vast majority of all the amount of stretching. Analysis of the role of linear temperature variation of the bridge structure, shut-in to determine the temperature variation of the bridge structure, the highest value and the lowest effective temperature effective temperature values.
