In obtaining a large number of reliable experimental data on the basis of the original JTJ 023-85 specification ball bearing laminated rubber bearings rectangle of additional test findings are incorporated in the transportation industry standards, and with the 1993 release of the transportation industry standard " roads and bridges laminated rubber bearings "(JT / T 4-93) .2003 years of experience in the application and summarize previous similar foreign product design, processing, testing and other related content specification elastic spherical bearings, standard on the basis of investigation , ball bearings combined with the actual situation in our country has conducted a number of tests. When laminated rubber bearings used in the bridge, ball bearing mounted between the bridge pier and beam, it is not only able to withstand and transmit loads unidirectional dynamic elastic spherical bearings, but also to adapt the beam end rotation and by rubber bearings shear deformation to adapt to changes in the telescopic bridge superstructure caused by the temperature. It is compared with steel bearings, ball bearing structure is simple, easy machining ball bearings, steel less (only steel bearing 1 / 6-1 / 30), low cost, low damping height, easy installation, and other unique advantages ball bearing design specifications in accordance with the reliability theory to complete the "highway reinforced concrete and prestressed concrete bridge design specifications" (JTG D62-2004), laminated rubber bearings for bridge design parameters have been revised, but for the transportation industry standard JT / 4 -93 was revised rubber bearings and issued a "highway bridges laminated rubber bearings" (JT / T 4 -2004) have been finalized with the 2006 and promulgated with JTG D62 and JT / T 4 -2004 supporting the transportation industry standard "roads and bridges laminated rubber bearings Specifications Series" (JT / T 663-2006). Currently, the laminated rubber bearing ball bearing publish specifications for the implementation of the relevant implementation, standards and world countries in the relevant specifications, standards converge and have the same level. According to the company's product information, technical performance ball bearing activities require unidirectional elastic spherical bearings, LRB part specifications series, strip rubber bearings, in order to control the vertical force generated due to bulge in elastic rubber middle have a hard rubber or synthetic fiber reinforced rubber bearings, ribbon rubber bearings are generally used for small amounts of concrete bridge stretching, such as hollow slab bridges, etc., for the purpose of supporting the vertical force. This type of rubber bearings as A type of bearing used in Japan, which is the horizontal force generated by an earthquake displacement limiting structure may assist other purposes to bear on a small ball bearing span bridge can replace oil blankets, ball bearings and other support of the use or sales of conventional and specialized telescopic pick absorption treatment, such holder in the form of sub Jianzhong frequently used, and a wide variety of structural forms and unidirectional slip elastic spherical bearings meet a variety of special requirements, which generally has the following structural formula in the form of form and structure. Rubber bearing sliding panels can be used on all structures span of less than 6m, and able to withstand deformation due to temperature changes commodities lag caused by contraction, can be used in many ways such activities board, in buildings such as the use of reinforced room top platform and supporting walls separated and the like. When these rubber bearings from two pieces of polystyrene foam lined skateboard composition, some ball bearings lined with side elastomers, some way they sided elastomers, PTFE plate embedded in two skateboard Room to improve Mocha coefficients.
