Bearing laminated rubber bearings are usually divided into two non-stiffening stiffening drink holder. Only one non-stiffening rubber bearing, although under horizontal force bearings to meet the needs of the horizontal shear deformation, but bearing in vertical loads tend to produce vertical deformation. In this case, the carrier is relatively small due to the constraint, and the incompressibility of the rubber, the lateral expansion of only the deformation of rubber, the rubber oil inevitably larger at the larger convex drum tensile deformation on the circumference thereof, thereby generating Stress aging. Such bearing on our roads and bridges is not recommended. In order to withstand large vertical loads can also meet the needs of horizontal displacement, the bridges are generally used stiffened laminated rubber bearing, rubber bearing stiffening plate steel stiffening material can be multi-directional activities ball bearings, glass fiber, cotton, nylon cloth, single-use our bridge stiffening material for steel, other materials not recommended, since as a stiffening plate rubber under vertical loads, steel embedded rubber sheet rubber between will limit the expansion of the convex side drum, vertical deformation corresponding decrease, thus greatly improving the bearing vertical stiffness. In this case, the sum total deformation bearing vertical deformation for each thin rubber sheet. In the design, the general requirements to use rubber bearing at least 30 years or more actual fixed ball bearing (GD type), foreign requirements are higher, such as the use of substandard products, not in three, five, ten it must occur within a few years the problem, when in the long run, will reduce the life of two-way activity rubber bearings ball bearings, and bearing damage occurs early, resulting in economic losses, which is now a major presence of laminated rubber bearings One of the problems, the Hope Project using the unit, not only as the main basis cheap to buy support. Installation and maintenance, the laminated rubber bearing installation and maintenance of ball bearings, but also the effect of laminated rubber bearings using a key influence and life, so in the newly revised industry standard, adds some requirements in this regard. If the installation is unreasonable, not the construction process, the construction process mishandling or branched cushion stone bearing the bottom center of the plate and beam receiving seat centerline do not coincide and so on. After the beam installation is complete, you may have a bias bearing goods does not appear to meet the requirements of the initial shear deformation, which are a direct impact on the effectiveness and use of rubber bearing life, so we must ensure that the construction of the two places and close contact bearings, bearing between the piers, so stand by force, does not allow partial pressure and void phenomenon. Sometimes after encountering construction is completed, the construction of temporary taken to prevent the displacement of fixed setting, no timely removal, in addition, the construction process because the installation of laminated rubber bearing capacity is quite large.
