Support mechanism single slit type bridge expansion joint device from the direction parallel to the bridge joints single group type bridge expansion joints, bridge expansion joints using thick steel plate welded longitudinal steel beams (currently used in the overall shape of profiled steel, referred stringer) and parallel to the axis of the bridge girder transverse support (the beam) of the composition. Stringer is divided into the side stringers and stringers with different forms of cross-section. For d60 Maurer joints bridge expansion joints, located only side rails, no expansion joints in the stringers and beams, its structure arrangement shown in Figure 5-1. Bridge expansion joints of the support mechanism shown in Figure 5-2. J-75 multi-slotted expansion joint device, due to the need to construct a bridge expansion joints on the stringer to Figure 5-3 arranged contact with the beams are connected. That is the number of beams in each group and the number is equal to the stringers. Bridge expansion joints, under normal circumstances should follow Sunny standards, regulations highway bridges telescopic device, also refer to the highway bridge expansion practical manual and other relevant monographs determined by calculation. Single Shallow Seismic Design of Bridges when caulking expansion joints, bridge expansion joints under the action of taking into account the level of a major earthquake, it is possible to partially bridge expansion joints without damage ah deadly disaster, therefore, bridges joints using design displacement grade damping 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. c40 steel joints prices, Guangyuan joints, free installation guide provided by the manufacturer Hengshui HaoTong Rubber Company.
