| Design angle: 0.006rad and 0.008rad |
| Equivalent damping ratio: >10% |
| Bearing displacement: the sliding type bearing along the bridge to the design displacement is + 100mm and + 150mm two, the transverse bridge to the design displacement is + 30mm; |
| Fixed type normal design shear strain is 1, earthquake is 2 |
| Friction coefficient: friction coefficient of sliding bearing design is 0.03 |
| Applicable temperature range: -40 C -60 C |
| Floating vibration isolation track/board support | Floating vibration isolation track/board support is composed of rubber damping bearing or steel spring damping bearing and viscous coupling wall-beam, its basic principle sets the damping bearing between rail/plate and foundation, this product has good shock absorption performance,suitable for railway, light railand underground rail suspension; all kinds of mechanical vibration isolation. |
| Cultural relics isolation box | Cultural relics isolation box is composed of core shock/vibration base and housing. Has a good vibration damping/ability, applying to earthquake action and external environment vibration excitation of the protection of cultural relics. |
| Vibration isolation platform | Vibration isolation platform has core energy shock/vibration bearing,has a good ability to reduce shock/vibration, used for all kinds of high precision equipment instrument, banking system, network system, and other important data protection. Prevent earthquake and vibration causing damage to the environment. |
| Bridge isolation bearing | Bridge isolation bearing is very stiff in nature, however,during earthquake,it becomes very flexible in horizontal direction so that it can reduce the earthquake force upon the bridges by changing its own shape. Most of all, it can spring back to its original shape after earthquake owing to high elastomeric property. |
| vertical bearing capacity, horizontal restoring force, damping (energy absorption) trinity; |
| bearing hysteresis characteristics (load - deformation curve) full, energy consumption significantly; |
| rubber formula improvement, equivalent damping ratio of up to 12%; |
| maintenance and management costs are low (no other damping devices); |
| after the earthquake residual deformation is very small, no need to change; |
| high damping bearing surface covered with rubber protection layer, protecting the inner rubber from ozone, ultraviolet radiation effect, with better ageing resistance, 50 years equivalent; |
| damping ratio decreased by less than 2%; |
| The temperature dependence of 7.HDR high damping rubber is lower, which is widely used in different climatic regions; |
| HDR high damping rubber with natural rubber has a better creep performance; |
| Environmental protection without pollution. |
| According to the bridge (housing and other buildings) local earthquake peak acceleration and selected directly corresponding bearing type specifications and should be considered in selection of bearing level stiffness and maximum shear strain test calculated whether meet the requirements of corresponding seismic force. |
| According to the span and the temperature change range, and considering the construction deviation and other factors, such as the selection of the corresponding displacement of the bearing. |
| Should meet the requirements of the space position of the structure of the actual bridge construction, the sleeve and the bolt should avoid the structural stress of the reinforced phase conflict. |
| Production is different according to the angle theta, rubber design shear modulus G value were different, the bridge construction engineer should be according to the actual situation of each bridge selection, in order to optimize the structure of the force and use, to ensure the products to play its due role. |
| 1 bearing arrangement should be considered whether the design displacement of the bearing is satisfied with the bridge due to the braking force, the concrete shrinkage, creep ,temperature, other common function and the displacement demand caused by earthquake. |
| 2 Displacement must not exceed the support design of the normal use of shear strain under normal condition of fixed support, the seismic status of the lower displacement shall not exceed the support design earthquake shear strain. |
| 3 continuous beam single joint length should not be more than 200m, span number should not be more than 6 cross; if you need more than 6 spans, bearing arrangement should be seized too near the displacement of sliding bearing fixed type support meets the displacement demand, again according to the situation of adding type sliding bearing or customization. |
| 4 rectangular fixed bearing is advised to use the bearing short side and the bridge to the parallel arrangement, when the bridge transverse size limit, can use the support long edge longitudinal bridge to the arrangement. |
| 5 when the sliding bearing is set, we should pay attention to the direction of sliding of the sliding bearing and the direction of the main displacement of the bridge. |
