Curved continuous girder bridge bearing arrangement affect the normal use of the bridge for a great, often due to improper bearing arrangement, or to limit support (fixed bearing and unidirectional sliding bearings) are exposed to horizontal forces underestimated, resulting in Some curved continuous girder bridge abutment, occurring at a temperature constraints limit the role of being cut, so that the occurrence of excessive bearing lateral displacement (even reach 20 ~ 30cm), a direct impact on traffic safety on the bridge. Germany EGG-ERT curve continuous beam bridge bearings arranged to do a detailed analysis for curved continuous beam due to the location and the way the fire fixed bearing slide bearing guide line layout is different, will cause a different bridge structure and lateral displacement binding. In order to ensure the seismic steel ball bearing seismic safety and reduce the amount of maintenance ball bearings professional custom steel structures, bearing arrangement i should make minimum constraint bearing on the structure, it must stand clear of permanent displacement and direction. Seismic steel ball bearing displacement by Emperor shrinkage and creep of concrete, and prestressed other causes, which concrete creep and shrinkage of the number and duration affected by many factors and can not be accurately predicted. In the displacement temperature shift in the life of the bridge will usually cause maximum displacement bearing, and the displacement of concrete creep and shrinkage is generally produced in a few years it is nearing completion. Considering the above factors curved continuous girder bridge abutment arrangement can be arranged by the polar radial and tangential arrangement of two ways. Seismic steel ball bearing is a bearing bridge bearing the earliest form. It consists of flat steel plates, steel plates in order to reduce friction on the contact surface, so as not to hinder the longitudinal sliding contact surface can be planed steel and coated with a graphite lubricant on the planer. The stereotype of thin steel plate sandwiched inspection, although helpful, but the stereotype is often squeezed out. If we can remove the dirt, dust, then inlaid with bronze self-lubricating graphite compound tablet will be able to work well. The amount of displacement of the single plate bearing is limited, and the support end of the beam can not be completely free to rotate. We determine the bearing disposal options based on the structural characteristics of the first bridge, around the web for the separation of structural steel damping steel ball bearings can be left and right pieces operations were replaced. Taking into account the structure of the bridge structure for the whole cast, respectively, from the top to avoid shear failure on the deck should be used at the same time from the top way. From the top of the equipment used should be considered unfavorable influence of various factors, access to more than 1.2 times the weight of the lifting calculation as the basis for selecting device. Second calculated bearing compressive modulus of elasticity permissible value (actual compressive elastic modulus have been unable to test measured), calculate the value of a constant external load bearing upper bear bearing according to the shape factor. Preparation for construction (1) according to the determined construction program, good working platform construction site erection, requiring replacement of a set of bearings erection every two brackets, such as the replacement of the bearings require abutment abutment and a location of the erection of a pier work platform, to facilitate the construction and monitoring of the operator to use, the work platform to be solid and reliable, to ensure the safety of personnel. (2) carry out the jack, pump supporting calibration. This bridge calibrated total of 16 sets of flat jacks, including 14 sets of steel from the top of the ball bearing, the other two to spare. (3) selection of the original holder of the same model new stand, and make a new test for detection of bearing work, supporting bearing dust cover.
