SSF-type bridge expansion joints device bridge expansion joints, is by Academy of Railway Sciences, Ministry of Transportation and Changshu xinjin 筑路机械厂 rubber products co-developed one of Modular bridge expansion joint products. 1, the structural characteristics of steel bridge expansion joints and rubber-piece telescopic device. Its structure is supported mainly by the force transmission system and the displacement control system in two parts. Support systems for power transmission power transmission system is supported by the intermediate beams, side beams, bearings and bearing support beam and pressed bearing components, shown in Figure 5-8. Bridge expansion joints with steel welded structure z80 instead of the overall shape of profiled steel bridge expansion joints, that middle beam machining railroad rails from bridge expansion joints c80, equilateral beam and beam components with general structural steel manufacture. Germany Maurer (Maurer) telescopic device bridge expansion joints bridge expansion joints d80, its force in the beam edge beams and stratified (above) after rolling profiled steel welded. Early use of box-shaped steel beams, structural steel beams and corrugated box side rubber strips (Figure 5-18), and provides 60mm and 80mm for the unit modulo two series (Table 5-7). More recent bridge expansion joints using Z-shaped side sill beams and king-shaped rubber band combination with bird-shaped structure (Figure 5-19) to 80mm of unit modulus series of specifications listed in Table 5-8. Bridge expansion joints displacement control system, in addition to have been made by using beams oblique angle change to achieve scalable solutions, and the use of elastic displacement control system as its main mechanism (Figure 5-20) HaoTong bridge expansion joints Rubber _ d80 _ bridge expansion joints supplied by Hao-engineering rubber.
