At home and abroad Modular bridge expansion joint device has various types, in addition to the shape and form of shaped steel with rubber seal are different outer F-type bridge expansion joint 60, and the physical and mechanical properties of rubber seals rubber band is basically our indicators specified in roughly the same. Single slit expansion joint device is determined by the Ministry of Transportation Highway Planning and Design Institute, Chang'an University (formerly Xi'an Highway Institute), Xi'an self Chemical Industry Company (formerly Xi'an self Rubber Factory) collaboration developed a series of expansion joint device f-type bridge expansion joints, Modular bridge expansion joints are in a class of device products. 1, the composition of the body was originally welding steel and rubber parts, structural features and principles of the single slit type bridge expansion joint device, formed by the steel beam system and the control box to withstand the support mechanism F-type vehicle loads bridge expansion joints, affects the beam displacement system produced by steel lever and the control arm to control the telescopic device Zhang closing transmission mechanism, as well as rubber seals, anchoring facilities and auxiliary pieces composed. SSF SSF expansion joint device type device type expansion joints, is one of the Academy of Sciences by the Ministry of Railways, Ministry of Transportation and Changshu xinjin 筑路机械厂 rubber products co-developed Modular bridge expansion joint products. 1, the structural features SSF-type steel bridge expansion joint device is combined with rubber 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. Welded steel instead of the overall shape shaped steel structure that middle beam machining railroad rails made of equilateral beam and beam components with general structural steel manufacture.
