Roads and bridges should be arranged within the support cushion stone steel mesh, bar diameter of not less than 8mm, 50mm * 50mm spacing appropriate for the double curved steel supports, should be connected to the vertical steel reinforcement inside the pier for pouring concrete pad stone strength Ratings should not be less than the C40, while the top surface of the concrete pad stone should be pre-calibrated with the level of foot, and strive to smooth rather 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 should be in the same horizontal plane seat height, 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. In order to facilitate understanding of the customer's control, it is more influential in the international foreign hands in relation to the bridge bearing damping arrangement made the appropriate integration, the reader is referred to the country. If you need further understanding can be found in the relevant standards of the original. Highway bridge bearings international hands synthetic rubber seismic isolation block, mainly for seismic requirements for laminated rubber bearing bridge made provisions tensile supports, highway bridge bearings which includes a three-part leaf spring seat, applied to the bridge isolation block design should adopt the relevant provisions. This standard uses and reduce highway bridge bearings, which uses the formula in order to protect against earthquake damage to buildings or bridges, where authentic isolation device interaction of synthetic rubber layer and stiffening plates stacked into plywood design, our call laminated rubber holder of a class structure type bearings, but according to the seismic requirements for the design of bearings, mounted on the superstructure and substructure inspection, can produce flexible, so that on the highway bridge bearing substructure from the two systems in earthquake , but also generate a buffer force to reduce the displacement of the isolation section, you can also reduce the seismic forces in the isolation period is passed from the foundation to the structure of the energy.
