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 supports, to prevent displacement of the beam device may fall and telescopic device relationship, it is generally desirable to prevent the displacement of the bearing displacement is less than the amount of bridge and a telescopic device, etc., roads and bridges bearing anchor bolts should pay attention to. For the length of anchor bolts, the general provisions bearing 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, highway bridge bearing on the number of anchor bolts using grid hinge support bridges span small holder wish to use two, even long-span bridges also want to control the 6 bit. Fixed bearing on the bridge, continuous cold end road bridge bearings Ball bearing fixed time, in order to resist earthquakes along the bridge along the horizontal force. Roads and bridges should be arranged within the support cushion stone bearing steel mesh limit, the bar diameter should be less than 8mm, spacing appropriate for the 50mm * 50mm, should be connected to the vertical steel reinforcement inside the pier for pouring concrete pad stone strength rating not less than C40, while the top surface of the concrete pad stone should be pre-calibrated with a spirit level, and strive to smooth rather than smooth, and ensure that the surface is clean, dry, sand and other fluorine-free. Highway bridge bearing pad stone top surface elevation should strive bearing pad stone top surface will be the same elevation level, this top must be strictly controlled. The same highway bridge support cushion stone height should be less than 0.5mm, its relative height should not exceed 1.5mm, to avoid bias, the initial shear deformation and appear uneven force phenomenon. Roads and bridges now pouring into every branch of installation is relatively simple, highway bridge bearing construction sequence, cleaning and sorting support cushion stone, the first branch before receiving seat cushion top surface of the stone bridge pier or remove loose sand table keep the pad stone top surface clean and free of oil, if the elevation deviation stone piers support cushion is too large, use a dry hard cement mortar to adjust. Ensure flatness and precision elevation pad stone. Limit bearing, bearing in Nantong, Hengshui Hao-Hao factory direct pass by Hengshui Rubber Company. Hengshui Hao-Engineering Rubber Co.
