Rubber bearings | rubber bearing truss plant 13833855982 | rubber bearing is provided by Hao-engineering rubber. Rubber bearings | rubber bearing truss plant 13833855982 | rubber bearing is Hengshui HaoTong Engineering Rubber Co., Ltd. (www.htgcxj.com) 2014 年 new upgrade launched in order to make rubber bearings to achieve these functions, we must indeed master bridge static characteristics and dynamic characteristics, and the appropriate choice of rubber bearings in the form it is very important. Depending on the size and form of bridge rubber bearing on the safety of the load supporting methods and horizontal forces should take full account of the size of the beam due to the amount and direction of stretching temperature changes, as well as live load deflection and torsional rotation produced. Meanwhile, there is a negative reaction force appeared rubber bearings should focus on selecting a form of resistance to the negative reaction force bearing performance. In addition to having rubber bearings main function, it must be to facilitate the construction and durability, ease of maintenance and management, and environmental coordination and economy to be fully considered. Construction rubber bearing most vulnerable rubber bearing structure constraints and upper and lower operating space construction error, therefore, in the design and construction plans for the rubber bearing installation location, ensure that the operating space, construction sequence and processing methods to be as careful study of construction errors. About function integrated and stand structure function separation type, according to the actual structure of foreign materials and structural examples can be considered. Rubber mounting bracket designed by earthquakes are classified at the earthquake off the beam due to the problem of the upper structure of the sliding rubber bearings, rubber bearings must ensure that human life does not appear damaged when security incidents off the beam, while the bridge should be based on important type rubber bearing control performance of the bridge will not reduce the problem is also very important. Accordingly, during an earthquake rubber bearings must be able to effect the inertia force of the upper structure and reliable delivery to the lower structure, the seismic force at all levels generated by the earthquake, should be able to meet the load transfer function and the adaptive function of the displacement of the basic design requirements . Japan's "Road bridge design specifications V- seismic design articles" in accordance with the provisions seismic performance of the carriage into two categories, namely for an earthquake (a relatively high probability of small and medium-scale earthquakes) and secondary earthquake (and has a small probability of occurrence Powerful earthquake) horizontal and vertical forces generated power, rubber bearing function can be guaranteed, but with two horizontal seismic forces generated supplemented by other structures to withstand displacement limit, and called the Class A bracket. Regarding the applicability of these bearings, the rubber bearings using B-type bearing when high damping rubber bearings basic, but because of constraints in the upper abutment structure is difficult to produce large vibration, even bearing damage, limited off beam The bridge may also be less likely to type A support.
