Ball bearing hinge plates commonly used rubber neoprene, natural rubber and EPDM rubber as a raw material, and prohibited the use of renewable live coriander vulcanized rubber processing seismic activity finished bearing, ball bearing hinge support the normal type of rubber plate with neoprene, cold-type bearing rubber sheet made of natural rubber or EPDM rubber. Rubber sheet rubber with physical and mechanical properties. Teflon plate ball bearing hinges just to providers use requirements for the use of Teflon sheet is also necessary finished strict seismic bearing in mind the relevant standard provisions should be molded from pure material should not be Use cutting boards, and should not use recycled materials, talk back slide finished plates embossed seismic bearing, the average particle size PTFE materials make up a greater than 50, molding pressure should go tetrafluoroethylene dollars depending on the type of raw materials top, generally not less than 30mpa, physical memory performance PTFE molded plate. Pot bearings with PTFE board design should allow pressure to 0mpa. Fabricated Teflon bearing plate and embedded in the gap between the slots according to their diameter size control in 0.5-1.0mm PTFE sheet surface should be smooth, not allowed to have a crack, dress, layered, does not allow impact damage and other mechanical defects, do not allow any entrained impurities. Meanwhile, the sliding surface of the Teflon grease board a plane should not stored fat storage tank and the size is not specified. 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 product development seismic fixed bearing, replace the bearing synchronous lifting program is selected, the replacement bearing money, first based on the structural characteristics of the bridge when change can be made with the implementation of the operation do not be 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.
