[Seismic] ball bearing hinge assessment requirements] [seismic ball bearing hinge assessment should be possible to adopt more scientific and rational evaluation of methods of mathematical statistics. As long as the same intensity, the same age, source materials, production process conditions and with the same ratio should be assessed using mathematical methods in order to be able to truly reflect the actual situation. The paper of the same batch beams can each hole or every two, three holes, as a number of small and medium-span bridge piles, capping beam, the number of holes can be used as a batch. The number of each batch of concrete specimens group should have too much, generally no more than 80 - 100 groups. [Seismic] As the ball joint bearing the same batch of the actual range of not more than one quarter, and the average daily temperature is less than 15 degrees is appropriate. Exceeds this range, you should not be regarded as the same batch, and were evaluated. [Seismic] ball bearing hinge assessment methods of mathematical statistics fixed hinge ball bearings, standard deviation S is an important parameter, since the intensity of use on behalf of the intensity of the mean value minus KS, if quite different specimen of finished concrete strength Fixed ball bearing hinge manufacturers, the big S, corresponding strength on behalf of the smaller value. Therefore, [the earthquake] ball bearing hinge construction companies must make possible a more uniform concrete strength, namely to reduce the S value, use it as a standard to measure the quality of enterprises, the construction process should not arbitrarily increase the amount of cement, but otherwise may result in more cement, but the consequences of failure. [Seismic] steel ball bearing hinge construction is a new type of energy saving building system, known as the 21st century's "green building." Therefore, in high-rise buildings, large factories, large-span spatial structure, transportation and energy projects, residential steel buildings can play to their own advantages, and again after the Wenchuan earthquake survey shows the steel structure with strong shocks. [Seismic] KTQZ series ball bearing hinge seismic steel ball bearings are designed according to the bridge seismic requirements. I plant more than 10 years of design, manufacture and use of ball bearings experience; referring to the ball bearing design approach of the European standard EN1337 requirements; using finite element analysis to design optimization. This series of ball bearings suitable for seismic intensity of 7 degrees and 8 degrees bridges. As a result of heavy-duty metal spraying and coating system, better adapted to the acidic, marine and other corrosive atmosphere environment. [Seismic] technical performance ball bearing hinge [seismic] vertical bearing capacity of the ball bearing hinge points 31: 1000,1500,2000,2500,3000,4000,5000,6000,7000,8000,9000,10000,12500, 15000,17500,20000,22500,25000,27500,30000,32500,35000,37500,40000,45000,50000,60000,70000,80000,90000 and 100000kN; 4.2 bearing angle is 0.02rad. 4.3 bearing can withstand a horizontal force to each fixed bearing GD, DX-way bearing activities transverse direction (along the bridge to be placed) or along the bridge (transverse to the placement) for bearing vertical bearing capacity of 15% (for seven seismic zone) and 30% (for eight seismic zone); [seismic] SX-way ball bearing hinge bearing activities because they do not withstand the horizontal forces, so both for seven seismic zone, but also for octave earthquake zone. This series bearing seven seismic zone seismic peak acceleration take 0.10g, eight seismic zone seismic peak acceleration take 0.20g; seismic fixed hinge ball bearings | Ball hinge bearing fixed | fixed hinge bearing finished by Hengshui Guangrun Engineering Rubber Limited.
