In order to achieve miniaturization of laminated rubber bearing, even increase the sealing rubber, compared with the highway bridge supports up to reduce costs. Using the rubber bearing itself changed into rubber bearings or insert pin lead rubber bearings, damping requirements can be achieved because the bearing structure in advance of mixed highway bridge bearings do not need support while using vertical and horizontal supporting both types of bearings, providing construction type and shorten the construction period is entirely possible. Since the multi-layered structure can be made, significantly improved vertical stiffness, the traffic generated by the vibration can be reduced. Highway bridge bearings and plain bearings comparison grid ball bearing hinges, hybrid bearings with ordinary laminated rubber bearing the following conditions are different in function in general; highway bridge bearings, plain laminated rubber bearings mainly applicable vertical load bearing function, fit and function rotational displacement, horizontal displacement highway bridge bearings suitable function, to ensure that the function held to overcome limitations due to the layered structure of the constraints generated grid bearing pads, proper natural cycle implementation and bearing in itself guarantee the stability of the case will have a problem. 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 bearing is critical that as much as possible to ensure the parallel beam bottom seat cushion and highway bridges support the top surface of the stone, flat on it with rubber bearings The following 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 of contact with the bearing precast beams shall ensure that the level of adjustment, highway bridge supports cellular or if there should be pre-tilt with sediment slurry leveling tamping. Properly seated rubber bearings, bearing press pouring in place require seismic slip bearing, girder off the beam when the beam should coincide with the longitudinal axis of the bearing centerline, plate girder and box girder longitudinal axis should parallel with the bearing centerline.
