The description of isolation bearings
The HDR high damping rubber bearing, Its structure is the same as ordinary
Laminated rubber bearings, high damping rubber bearing is improved through
Rubber formula, so that the rubber material damping is increased, so that the
Bearing's damping ratio can reach 15-18%. This series of bearing is suitable for
9 degrees earthquake intensity area of highway and municipal bridge.
By improving the formula, so that the rubber material damping is increased, so that
The bearing's damping ratio increase, achieve the isolation effect.

OUR LEAD RUBBER BEARINGS ON EXHIBITION
Bridge bearings and expansion joint are important parts of whole bridge components, but the amount money that spent on bridge bearing and expansion joint is only 2-3.5%, it is absolutely a wise choice to evaluate it within the whole project to prevent failed choice bringing unnecessary costs.
The types of isolation bearings1. According to the Isolation property points(1)Ordinary rubber isolation bearingOrdinary rubber bearing is vulcanized by multi-layer rubber sheet and steel sheet, And then glue them together; Product specification 100 mm-800mm in diameter, Bearing is capacity of dozens of tons to one thousand tons, have large shearDeformation ability. (2) Lead rubber bearingsThe lead rubber bearing is vulcanized by multi-layer rubber sheet and steel sheetAnd glue them together, then pour lead into center hole; Product specification 200mm -1200 mm in diameter, bearing capacity of dozens of tons to one thousandTons, has large shear deformation ability and yield. (3)High-performance isolation bearingsHigh-performance isolation bearing is composed of excellent performanceIsolation components; Product specification is 200 mm -1200 mm in diameter, Bearing capacity of dozens of tons to one thousand tons, has large shearDeformation ability and yield. High-performance isolation bearing technology isNot only excellent performance, but also has simple structure, low cost, easy toChange after installation. (4)Three-dimensional isolation bearingThree-dimensional isolation bearings with horizontal and vertical shock absorptionAbility of isolation components, set the level of isolation and vertical shock (vibration)Is an organic whole; Product specifications 200 mm - 1500 mm in diameter, levelHas larger shear deformation ability and the yield strength, vertical has biggerBearing capacity and stability. Three-dimensional isolation bearings can verticallyIsolate earthquake, also can isolate the subway and various kinds of vibrationCaused by machine, which is suitable for isolation areas, the rail transit construction, High precision instrument production workshop and a variety of valuable instrumentAnd equipment protection of cultural relics. 2. According to the vibration territory point(1)Floating vibration isolation track/board supportFloating vibration isolation track/board support is composed of rubber dampingBearing or steel spring damping bearing and viscous coupling wall-beam, itsBasic principle is set the damping bearing between rail/plate and foundation, thisProduct has good shock absorption performance, suitable for railway, light rail andUnderground rail suspension; All kinds of mechanical vibration isolation(2)Cultural relics isolation boxCultural relics isolation box is composed of core shock/vibration base and housing, Has a good vibration damping/ability, apply to earthquake action and externalEnvironment vibration excitation of the protection of cultural relics. (3)vibration isolation platformVibration isolation platform has core energy shock/vibration bearing, has a goodAbility to reduce shock/vibration, used for all kinds of high precision equipmentInstrument, banking system, network system, and other important data protection, Prevent earthquake and vibration causing damage to the environment. (4)Bridge isolation bearingBridge isolation bearing is very stiff in nature, however, during earthquake, itBecomes very flexible in horizontal direction so that they can reduce the earthquakeForce upon the bridges by changing its own shape. Most of all, it can spring back toIts original shape after earthquake owing to high elastomeric property. The advantage of isolation bearings1. The trinity of the vertical bearing capacity, level of restoring force and damping(energy absorption)2. Bearing hysteresis characteristics (load -deformation curve) fully, energyConsumption significantly3. Rubber formula improvement, the equivalent damping ratio can reach more than12%4. Low maintenance cost (no other damping device)5. Little residual deformation after the big earthquake, don't need to replace6. High damping bearing surface covered with rubber protection cover, whichPrevents the internal rubber from being affected by ozone, ultraviolet ray, has betterAging resistance, 50 years of equivalent damping ratio less than 2%7. Its low temperature dependency, widely used in different climate regions8. HDR high damping rubber and natural rubber with superior creep properties9. Environmental protection, no pollutionAs your request, the high damping rubber bearing can be manufactured inRectangular or round shapes. Custom sizes and designs are also welcomed. What is the good successful case of the isolation bearingA: In fact, as early as the MID-1990-s, building isolation rubber bearing showed itsExcellent isolation performance. The region of an earthquake, Osaka and kobe, Japan is the real one. On January 17, 1995, Japan kobea 7.2 -magnitudeEarthquake, caused the shocking heavy losses. In the earthquake, 35 kilometersFrom the epicenter of the west of the men in the post office base isolation technologyHas played a very good isolation damping effect, it is in the field of earthquakeHazard level has reached the degree of 7 (equivalent to China's earthquake intensityOf 9~10 degrees), in the earthquake and after the earthquake, the whole building isAs usual.
We ZAOQIANG DACHENG RUBBER Co., Ltd are the state-owned company as the overseas sales company of Hengshui Rubber Co. Ltd, which is iniated in 1954 and located in High and New Technology Industrial Park, Hengshui City, Hebei Province, the company has held the enterprise spirit of "solidarity, progress, pragmatic, contribution, and striving to be the first" and adhered to the quality guideline of " market oriented technical progress, taking the lead in the industry with quality, keeping good faith to ensure customer satisfaction".
