Germany Maurer (Maurer) bridge expansion joints fd80 telescopic device type joints, its force in the beam edge beam and hierarchical (above) after rolling profiled steel welded. Early use of steel box beams, structural steel beams and corrugated box side rubber composition (Figure 5-18), and provides 60mm and 80mm as a unit modulo two series (Table 5-7). More recent bridge expansion joints using Z-shaped side sill beams and king with a bird-shaped rubber band combined structure (Figure 5-19) to 80mm as a unit modulus series of specifications listed in Table 5-8. Bridge expansion joints displacement control system d-type expansion joints, in addition to have been made by the use of beam oblique angle changes to a stretching program, while the use of elastic displacement control system mainly mechanism (Figure 5-20) for bridge expansion joints high grade highways sprung d40 type expansion joints, expansion joints sharp increase in road traffic, axle vehicles traveling on the road speed and the vehicle is growing, people are driving comfort and other requirements are also increasing the use of thick steel plate welded made of vertical steel beams (currently used in the overall shape of profiled steel, called stringers) and parallel to the axis of the bridge girder transverse support (the beam) of the composition. Stringer bridge expansion joints are divided into the side stringers and stringers XF-type bridge expansion joint device has a cross-section of different forms of support are oblique bridge expansion joint device type is determined by the Ministry of Railways Institute of Railway Construction, Hebei Hengshui City Rubber Co., Ltd. and Shijiazhuang Traffic Survey and Design Institute in 1993 jointly developed the Modular series. Bridge expansion joints for use of various types of new bridges, but also for the telescopic device to replace the old bridge into the selection. The product is an interlocking chain-link mechanism bridge expansion joints, has a good stretch uniformity, and won in 1999 the Ministry of Communications Science and Technology Progress Award fd80 type joints joints _ _ Linfen Hengshui Hao-factory outlets by Hengshui Hao-Rubber Limited. Hengshui Hao-Engineering Rubber Co. (www.htgcxj.com) strong, credible, Hebei Hengshui site construction materials industry has accumulated a large number of loyal customers.
