Rubber ball bearing hinge bearing support and implementation in steel plate with rotation set with flat Teflon plate and stainless steel plate sliding displacement of the bridge to meet the requirements KLQZ seismic bearing steel ball joints, the basic performance requirements , GKQZ under the existing provisions relating to the seismic industry standard steel ball bearing hinges, ball bearing hinge technical performance as follows (1) vertical bearing capacity (reaction force) stand in a vertical design load, the bearing Supports compression deformation value not greater than 2% of the total height, sight port basin deformation ring suppliers shall not be greater than 0.5% spray yellow outer diameter, bearing residual deformation shall not exceed 5% of the total amount of deformation. (2) the level of carrying capacity: horizontal bearing fixed bearing in each direction and a one-way bearing activities of non-slip direction shall not be less than 10% bearing vertical bearing capacity, seismic bearing horizontal bearing capacity of not less than 20% holder of the vertical bearing capacity. (3) Corner: ball bearing hinge vertical rotation angle provisions shall not be less than 0.02rad (4) the friction coefficient: room-based activities designed bearing friction coefficient of less than 0.03 hardy type of activity is not greater than the coefficient of friction bearing design. 0.06 (5) Displacement: When the current ball hinge bearing products, bearing the rebate is divided into 31 according to the corresponding displacement So, bearing activities exceed the value of the amount of displacement of the table, may be appropriate according to actual needs increased. Supports single transverse direction for individual activities have different views on whether to allow the amount of displacement. Supports control only the physical and mechanical performance requirements and component quality. Laminated rubber bearings from the case in recent decades on the highway bridge used, in addition to the transportation industry standards set forth in species, there were a few varieties rebate fulcrum bridge superstructure beyond industry standards for 150 ~ 8000KN of bridge seismic steel ball bearing hinges, and more generally the use of laminated rubber bearings. Ordinary laminated rubber bearing for smaller bridge spans and small displacement PTFE slide rubber bearing suitable for large-span, multi-span continuous GJQZ large displacement seismic steel ball bearing hinges, Charpy and continuous panels structure bridge beams, sliders, etc. It can also be used as a continuous beam of laminated rubber bearings and small push in the T-beam traversing bearings used are usually divided into two non-stiffening stiffening drink holder. Only one non-stiffening rubber bearing, in effect, although bearing horizontal force H level to meet the needs of shear deformation, but in the role of the vertical load bearing R tends to produce vertical deformation does not recommend the use of other materials, stiffening Self-made rubber plate in the vertical loads, steel embedded rubber sheet rubber between will limit the expansion of the convex side drum, vertical deformation is reduced accordingly, thus greatly improving the bearing vertical stiffness HaoTong earthquake engineering rubber ball _KLQZ hinged steel ball bearings _ seismic steel bearing hinge provided by Hao-engineering rubber.
