XF-type bridge expansion joint device bridge expansion joints are oblique-bearing bridge expansion joint device z80 bridge expansion joints, is made by the Ministry of Railways Institute of Railway Construction, Hebei Hengshui City Rubber Co. and Shijiazhuang Traffic Survey and Design Institute in 1993 The jointly developed Modular series. Bridge expansion joints and structural features principle: bridge expansion joints, mainly by the edge beam, the beam, the sealing rubber band, diagonal support beams, bearing pressure and compression, displacement control box and anchor steel components. Its edge beam and shaped steel beams using domestic extrusion. Its cross section is arranged as shown in Figure 5-12. Bridge expansion joints required beam length upper structure generated by the seismic force structure and the lower the maximum relative displacement between the top, when a single calculation, do not open the rate of bridge and prevent displacement effect limiting device 160 bridge expansion joints, And judging liquefied foundation to consider when its effects. Ground deformation due to earthquake ground relative displacement occurs when the minimum required beam bridge expansion joints bit longer. Ground deformation earthquake d40-type bridge expansion joints, the impact of the seismic acceleration power is different, but the foundation of types. The distance between two of the lower structure required impact. Xieqiao required skew bridge girder bridge expansion joints required long beam length, parallel to the support line is not asymmetric skew bridge should meet the requirements of the following formula. Xieqiao required for beam length. The length of the row of the upper structure. Bridge expansion joints bend bridge beam length required. z80 Shandong bridge expansion joints bridge expansion joints _ _ ho-ho Rubber pass by Hengshui Rubber Company. Hengshui Hao-Engineering Rubber Co. (www.htgcxj.com) strong, credible, Hebei Hengshui site construction materials industry has accumulated a large number of loyal customers.
