Ball bearing hinge is determined by a sliding plate and elastomer composition supporting circular basin ancestors, where it is inserted elastomer Xiazuo tank side panels, such as the middle of the dry plate and then seal damping elastomer hinge ball bearing, the intermediate plate and the upper plate know petals projecting upper seat embedded in the middle of a steel sheet to construct a part of the structure. Such activity of the carriage is moved above the level of the sliding plate to the matter, the use of the full range of the rotation function to complete the elastomeric seal, and a fixed abutment, the intermediate plate is embedded in the upper plate to interact directly with the excel on the small plates are replaced only by deformation of the elastomer seal into the rotation function. In the bottom of the basin of the top surface of the rubber sheet insertion compression rings, wooden thing is to organize the elastomer is extruded from the gap under the bottom pot of weeks to avoid the intermediate steel. The late 1950s began to develop abroad and applied ball joint bearing, ball bearing hinge in 1959 successfully developed in Germany and used on the highway bridge, a long time by the operator, and achieved good results the future of the world have specialized manufacturers have pot bearings, and bearing design tonnage is also increasing, the standard design of Japan in 1976, there 0.5-5mn pot bearings, our Ministry of Railways since 1975 to The performance ball bearing hinge conducted a comprehensive study and design completed Red River railway cable-stayed bridge with the bearing, and with the 1990 completion of the industry standard "highway bridge rubber bearing basin" (JT 3141- 90) formulation, to 1999 were developed to form a new industry standard, "highway bridge rubber bearing" carrying capacity of the original standard 1000-2000kn holder, increased to 1000KN, expanding the scope of the current Longitudinal activity ball bearing hinges, ball bearing hinges on a wide range of applications shall be subject to our roads and bridges, and has become one of the main highway bridge abutment formation SX type bidirectional slide ball bearing hinges, the new industry standard is being revised . The number of theoretical studies also wired, can learn from the data page is not so complete and perfect, however, in the country has also been the emergence of practical engineering experience are constantly accumulating, especially in the construction process using computer-controlled synchronous hydraulic jacking also in the development and continuous improvement is expected in the future with some aspects of the technology to achieve rapid development, Synchronous Lifting bearing replacement program is selected, the replacement bearing money, first of all should be based on the structural characteristics of the bridge, with the changing time can Do not carry out the implementation of the operation made equal. Should generally use synchronous lifting construction is reasonable and reliable manner. Order of the equipment used, according to the data, should be considered jacking various unfavorable factors to calculate the weight of more than two times as a lifting device to select the fundamental basis, that is, safe absorption lifting equipment should be greater than 1.2.
