XF-type bridge expansion joint device bridge expansion joints are oblique-bearing bridge expansion joint device is determined by the Ministry of Railways Institute of Railway Construction, Hebei Hengshui City Rubber Co. and Shijiazhuang Traffic Survey and Design Institute jointly developed in 1993 in The Modular series. Bridge expansion joints and structural features principle: e-60 bridge expansion joints bridge expansion joints, mainly by the side of the 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, under normal circumstances should follow Sunny standards, regulations highway bridge expansion device cqfc40 type bridge expansion joints, also refer to the highway bridge expansion practical manual and other relevant monographs determined by calculation. Single shock absorber when the bridge design, bridge expansion joints taking into account the role of rating earthquake, bridge expansion joints have been damaged may be partially but not when ah deadly disaster joints, therefore, bridge expansion joints using rating cut design displacement shock device type as the basic design parameters of reasonable amount of stretching its design can be determined according to the following formula. Bridge expansion joints Furthermore, due to the level of vibration generated by earthquakes, often, the situation is more complex multi-direction, so in addition to the amount of stretching and accurate use of the design, the more important is the telescopic device itself should have the ability to adapt itself in this regard, bridge expansion joints monograph dedicated manual epilogue, on adaptation research and development of three-dimensional displacement telescopic device made an appeal, which is not only much-needed bridge expansion joints of the bridge project development, bridge seismic design issues also need to be considered. cqfc40 type bridge expansion joints, expansion joints Liupanshui, online ordering factory support provided by Hengshui HaoTong Rubber Company.
