Relations highway bridge bearing installation should pay attention to the installation of the upper structure, namely longitudinal bridge, the lower edge of the beam width, thickness and processing the positional relationship between the firmware and bearing bolts and bolts length. Relationship with the lower structure installation, namely with the bridge of the parapet contact state highway bridge supports full-height display, roads and bridges and bridge abutment contact surface edge distance, and adjacent structures installed relationships that stand on the pier installation, When the relationship between the width and length restrictions, and adjacent structures installed on the piers and road bridge bearing pedestal installation, bridge width and length restrictions. Relationship with anti-fall device and telescopic beam device, and bearing ball bearing hinge to prevent displacement of the beam device may fall and telescopic device relationship, it is generally desirable to prevent the fall of less than bearing displacement device and telescopic beam displacement device amount of bearing, roads and bridges bearing anchor bolts should pay attention to. For the length of anchor bolts, the general provisions of bridge design specifications must be difficult to guarantee the role of anchor bolts, so the use of more than 25mm in diameter of the anchor as well, the number of highway bridge bearings using anchor bolts on the bridge span smaller Supports wish to use two, even long-span bridges also want to control the 6 bit. Fixed bearing on the bridge, when a continuous cold end road bridge bearing fixed, in order to resist earthquakes along the horizontal force along the bridge. When the highway bridge support reaches the yield, stiffness after yielding highway bridge bearings, so LRB's hysteresis curve is equivalent to an initial elastic stiffness and stiffness after yielding fixed bilinear curve has twisted branches The initial elastic stiffness seat, highway bridge bearings, according to the seismic design of highway engineering specifications, minus capital contribution of the elastic modulus of rubber bearing plate bearing the stiffening cross pin lead after deducting the area, bearing the total thickness of the rubber layer. Secondary roads and bridges bearing stiffness and bearing displacement efficient design, cross-sectional area of ??lead pins, roads and bridges yield load bearing highway bridge bearing shear strain, lead bearing shear stress corresponding yield load Lead shear stress. Highway bridge bearings corresponding yield load of lead bearing shear stress 3d3s grid, according to the structure of the test, the LRB initial elastic stiffness, it is desirable for the second stiffness 15 chanting, and with the lead pin diameter increases, bearing the initial elastic stiffness has gradually improved. wjkgz grid bearing seat _ _ Changsha buy bearing manufacturers offer free design HaoTong by Hengshui Rubber Company.
