Ball bearing amount is too large spherical bearing pot bearings, the factors affecting the quality and great, so you can not put a lot more work ahead of yellow rubber bearings for posterity, although designed to replace the measures considered, but so many of plate replacement That is called the Department of bearing no small task, so the pot rubber fixed bearing, ball bearing bridge designer and expensive to be a good first off. Bridges and culverts in the revision of norms and bearing industry standards, the project team on disposal of information and international standards, foreign standards and domestic willing to reach all relevant technical levels were fully reflected, revised standards, and norms solicit light system design, construction, production, management and the opinions of experts, but also to seek the views of system-level detection, municipal, quality supervision, the manufacturer's advice. One type of ball bearing type are rubber bearing, in earthquake-prone areas must be considered earthquake building bridges so that when local earthquake can make a bridge to maintain its function, so as to ensure the smooth progress of relief and post-earthquake work. Reduce the losses caused by the earthquake, damping ball bearing design, rubbing the bridge structure can support up ball bearings in so long period of structural vibration while LRB dissipated by vibration energy, thereby reducing the damage to the bridge structure seismic crews. With cement mortar with a test stand, adjust and determine the actual use of the test materials engineering should be used with mortar test should be used with mechanical stirring, mixing time shall not be less than 120s, ball bearings or look-up table are calculated in accordance with the ratio When stirring, should be determined stratification of its consistency and mixing thereof, when not meet the requirements, the amount of material should be adjusted, so far known to meet the requirements, and then try to determine the timing of the reference mortar mixing ratio of the spherical seismic sliding bearing , should at least try with the use of three different mixing ratio, the ball bearing one of the preceding paragraph, the reference mix, ball bearings with other cement ratio should be compared with the benchmark increased or reduced by 10% , to ensure the consistency of the eligibility conditions of stratification, water can be adjusted accordingly. For three different mixing ratio after adjustment, should be required to existing relevant standards of molding, strength testing mortar, ball bearings and selected in line with the requirements of the test with strength and with the minimum amount of cement with a manhole ratio. Reference with cement mortar cement mortar mix ratio. Spherical rubber bearing basin _ _ Lishui bearing manufacturer to find a seat provided by Hengshui Hengshui Hao-Hao Tong Rubber Co. project.
