| 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. |
| Vertical bearing: through the steel plate to provide a stable and reliable vertical bearing capacity, to ensure the safety and reliability of the daily use of the building. |
| The level of stress: high intensity of natural rubber, and bonding steel plate relay which is reliable, horizontal direction are subjected to daily vibration, wind load and earthquake huge shock wave can ensure the building not because all of a sudden internal damage caused the failure of. |
| Isolation design theory: consumption in seismic transmission level of the vibration energy by means of special damping properties of the composition, in the earthquake, in the vertical direction to provide support to the building and in the horizontal direction not all the energy transfer to buildings. In the seismic wave reciprocating action vibration energy is converted into heat consumed, greatly reducing earthquake on building capacity for destruction. |
| 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. |
