After consideration of the use of temporary bearing cast body, should be the strength of concrete beam to meet the design requirements, road bridge bearing roof beams and remove the temporary abutment and templates, exact placement of permanent rubber bearings, rubber bearings off the beam when by force, and check whether the beam bearing and close, if there Void phenomenon and with ease, should be timely adjustment process. Precast girder highway bridge bearing installation, installing precast slab rubber bearings The key is to ensure as far as possible in parallel, flat grid ball bearing hinge highway bridge support beam bottom and the top surface of the stone seat, so that it on rubber bearings under full of tight, avoid bearing bias, void and uneven and supported phenomenon. Construction sequence and precautions bias precast beams laminated rubber bearing, bearing void and uneven, according to the pouring of support cushion stone cleaning requirements and challenges, highway bridge bearing pre-deal support cushion stone. Precast beam end bearing is not placed at the bottom of the handle; bottom plane bearing precast beams and should ensure that the level of contact with the seat adjustment, highway bridge bearing cellular or if there should be pre-tilt with sediment slurry leveling tamping. Properly seated rubber bearings, bearing press pouring in place requirements when falling girder beams, beam centerline longitudinal axis should coincide with the bearing plate girder and box girder longitudinal centerline and should stand parallel. When using the role and seismic forces on the grid sliding bearings highway bridge bearing damping bridge, should be less than the ordinary use of non-damping rubber bearings bridge seismic force of 70%, the LRB big earthquake After level displacement should be less than or equal to 2.5, highway bridge bearing lead pin height and diameter should satisfy the formula, based on the principle of Lead configuration requirements can be calculated once the kind of rigid LRB, the secondary stiffness , the characteristic parameters equivalent stiffness and equivalent spherical steel bearing coefficient qz, and come from the original natural cycle bridge computationally intensive statistical analysis of the actual bridge. Meanwhile, combine the damping capacity and bridges cried damping demand for lead-pin line drawn damping bridge design using LRB selection series chart, this is only the principles and methods for our roads and bridges lead pin rubber will do the standardization work of direction, but one should be further research into the issue. Highway bridge bearing applications and should pay attention to the problem of highway bridge bearings and unleaded ordinary rubber bearing pin has a larger and larger compared to the beginning of the elastic stiffness.
