Highway bridge laminated rubber bearing a highway bridge laminated rubber bearing (JT / T4) works an ordinary multi-layer laminated rubber bearing rubber sheet and stiffened steel plate, and the plate is formed of all the packages in the rubber elastic material rubber bearings. Bearing plate has sufficient vertical stiffness to the vertical load bearing, the upper structure of the reaction force can be reliably transmitted to the pier, with good flexibility to adapt to the beam end rotation; there are large shear deformation to meet horizontal displacement of the upper structure. 2, tetrafluoroethylene laminated rubber bearings is an adhesive layer thickness 1.5-3mm a Teflon plate made in the ordinary laminated rubber bearing. In addition to ordinary laminated rubber bearing vertical stiffness and elastic deformation, can withstand a vertical load and adapt to the beam end rotation, due to the low friction coefficient of ethylene tetrafluoroethylene and stainless steel plate between the beam bottom (μ≤0.08) allows the upper bridge construction The horizontal displacement is not limited. Please refer to: the scope of application of laminated rubber bearings and tetrafluoroethylene rubber bearings and installation technology II highway bridge laminated rubber bearing code and representation of the structure of the bridge laminated rubber bearing type classified as follows: a round ball crown laminated rubber support Block (TCYB series) ordinary laminated rubber bearing --- rectangle ordinary laminated rubber bearing (GJZ series) Round ordinary laminated rubber bearing (GYZ series) laminated rubber bearings round tetrafluoroethylene laminated rubber bearing (GYZF4 series) --- PTFE laminated rubber bearing laminated rubber bearing rectangular tetrafluoroethylene (GJZF4 series) spherical cap tetrafluoroethylene laminated rubber bearing (TCYBF4 series) The plate bearing itself has sufficient vertical stiffness to meet larger vertical load, and has good flexibility to adapt to the beam end rotation. Also it has a large shear deformation in order to meet the horizontal displacement of the upper structure; can produce a good shock effect, can reduce the effect of dynamic load on the upper structure and pier. Since the laminated rubber bearing with a horizontal cut isotropic, we can deliver good upper structure and more deformed. In turn, the bridge of the use to advantage. Except the ordinary bearing function, but also has a force acts upon the beam end to adjust the position by force through the center of the spherical surface of the rubber layer, gradually spread to the power circle laminated rubber bearing steel and rubber layer, so that branch Block by force, especially for skew bridge, overpass bridge slope places. Third, the laminated rubber bearing according to types of plastic Temperature categorized as follows: a, neoprene: Temperature + 60 ℃ ∽-25 ℃ b, natural rubber: Temperature + 60 ℃ ∽-40 ℃ c, EPDM Fourth, the scope of a laminated rubber bearing, laminated rubber bearings highway bridge applies span of less than 30m, a small displacement of the bridge different plane shapes for different bridge structure, the bridge orthogonal rectangular support.; curved bridge, skew bridge and bridge pier with circular cylindrical bearings. 2, PTFE laminated rubber bearings for large span, multi-span continuous, large amount of displacement bridge simply supported beam structure continuous panels. It also can be used continuous beam by pushing and T-beams traverse the slider rectangular, circular tetrafluoroethylene laminated rubber bearing applications other non-rectangular, circular ordinary laminated rubber bearing the same. Installation and construction of laminated rubber bearings Method five, two installation and construction of highway bridge laminated rubber bearing cast girder bridges ordinary laminated rubber bearing installation more convenient, the construction process is as follows: to keep the top surface of the cleaning pad stone piers. If the bearing pad stone elevation gap is too large, it can be adjusted with cement mortar. The support pad stone by design icon of the center, the center of the stone bearing pad centerline when installing rubber bearings to fit, to ensure that the seat position is accurate. When a beam with two or four seat when necessary, to facilitate the leveling layer of cement mortar can be between the support and bearing pad stone, so bearing automatic leveling at a pressure of bridge body. Before casting the beam, place a larger plane than the bearing support plate, welded steel anchor bars and the beam connection, and treated as part of the supporting steel beam template were pouring water, according to the above method on a support, can so that the beam bearing pad stone bottom plate and the top surface of all the dense paste. Precast rubber bearing installation: key installed precast rubber bearings is to ensure that the parallel beam bottom pad stone top surface, flat, making it and the stand, all of the lower surface of tight, with no bias, off Empty and uneven support tolerance phenomenon. Construction procedures are as follows: to handle support pad stone, the support pad stone elevation consistent. The bottom surface in contact with the bearing precast beams to maintain the level and flat. When a cellular slurry and inclination, to advance with cement mortar tamping, leveling. Properly seated before the rubber bearing and support so bearing pad stone in place exactly as designed. When the girder off the beam, T-beam longitudinal axis to coincide with the bearing centerline; plate girder, the longitudinal axis of the bearing box girder parallel to the centerline. To drop the beam accurately, in the frame of the first inter-plate girder or box girder, can mark the location of two cross bearing center beam at the end, at the end of the facade of the beam position mark both bearing centerline vertical line, so that when the beam fell coincide with the position of the center line of the piers on the phase. After several cross beams can be in accordance with the first span as a reference. When girder beams down to a smooth, prevent pressure bias or generating an initial shear deformation, we can refer to the railway bridge laminated rubber bearing specification table. When installing T-type bridge, when the beam reinforcement bottom width ratio rubber bearings should be between the seat bottom and beam bar plus set larger than the bearing thick steel reinforced concrete pad or do transition, in order to avoid bearing the local pressure, and the stress concentration. Thick steel reinforced concrete pad or use epoxy mortar and adhesive bonded bottom reinforcement beams. After falling beams, seat top surface is level with the beam surface under normal circumstances. Prestressed Simple Beams, its top surface tilting seat later; non-prestressed girder its top surface can seat slightly forward, but the inclination angle shall not exceed 5 ";. laminated rubber bearing (GYZ, GJZ series) usually made up of several layers of rubber sheet and steel plate (steel plate as a rigid stiffener) combination. The layers of rubber and its upper and lower plates by press vulcanization firmly bonded into one, the product has sufficient vertical stiffness to withstand the vertical loads, and Pressure upper structure can reliably transmitted to the pier; there is good flexibility to adapt to the beam end rotation; and a great shear deformation to meet the horizontal displacement of the upper structure; with a simple structure, easy installation, save steel, low prices , maintenance is simple, easy to replace and so on. The product also has good shock effect, can reduce the effect of dynamic load on the bridge span structures and piers. Teflon skateboard rubber bearing (GYZF4, GJZF4 series) is a flat plate rubber bearing the same size and thickness of 2 ~ 3mm PTFE plate using a special adhesive bonding technology to make the rubber bearing surfaces together for vulcanization. It is in addition to a plate bearing the characteristics of the outer , but also to meet support reaction force, a small tonnage and horizontal displacement require large bridges, this seat is not only suitable for large-span simply supported bridge, but also for continuous bridges, but also the role of bridge top Push the slider in the construction of an adaptive temperature neoprene type:. +60 ℃ ~ -25 ℃ natural rubber type: +60 ℃ ~ -40 ℃ EPDM Type: +60 ℃ ~ -45 ℃ load rating 100KN ~ 10000KN, special specifications made by the user prior production.
