Ball bearings as an effective bridge structure damping device has been applied abroad bridge device. Vertical stiffness, bearing good performance, stable bi-supported bridges superstructure sliding elastic spherical bearings, moderate levels of stiffness, which can meet the earthquake generated large displacement. Better performance, ball bearings have the energy absorbing seismic ground brought a large earthquake resistant ball bearing life expectancy under normal circumstances can reach 50 years. Spherical plain bearings are squeezed into a laminated rubber bearings with lead or multi-pin, a bearing structure in order to improve the performance of rubber bearing structure. LRB withstand the weight and horizontal forces of the bridge structure, lead lag pin can produce plastic deformation to absorb energy and to provide horizontal restoring force by rubber, therefore, shot type support both isolation but also has a good effect Bidirectional slip elastic spherical bearing, type an earthquake zone improve seismic bridge abutment level ideal form. The general structure of rubber bearing structure is simple, according to the Japanese zodiac signs bearing design standards related to damping provided by said pressure is 1500 ~ 2600kn the LRB bearing design and production of finished products. Over a long period of questions about the elastic spherical bearing, spherical bearing in the horizontal displacement earthquake increases, the so-called unitary structure (ie feature to type) is necessary to mount a plurality of functions as constituting integration, in order to collection of various functional units constructed abutment, is ever more commonly used form. Ball bearing special bridge and foundation problems resonate in the soft ground, it must be fully aware of this when using. Supports true reflection of the structural design, since the transfer bridge displacement and force are bi-directional movable elastic spherical bearings, must be arranged to satisfy this condition. Centralized functions constituting the abutment member of a ball bearing structure and the body of each function will be designed as an independent structure, which constitutes the completion of a set of bearing the role of function-separation type bearing structure. According to current thinking and ball bearing case and abroad generally used on roads and bridges, for the use of materials and necessary functions and structure, etc., may consider a variety of forms.
