In the choice of ball bearings KQGZ seismic steel ball bearing, should also be noted, as long as the beam end bearing deformation turn to meet the requirements, bearing the thickness of the thinner more favorable, because the bearing to withstand the horizontal forces not by bearing shear deformation again when the overall design is completed the bridge structure, but also give full consideration to the fixed ball bearing, bearing activities and forms part of the curved bridge abutment structure and reasonable layout. In our country has always been a bridge and culvert specifications and industry standards steel ball bearing steel KQGZ earthquake on ball bearings in both design and construction and acceptance requirements must be made with the beam end bearing, bearing, snug contact with the pier and down, the ball-type bearing force uniform, with no void phenomenon, rubber bearings in the best force uniform, with no void phenomenon, to ensure the ball bearing in the best stress state, when the beam has a longitudinal, should be Leveling treatment. Currently, the world bridge normative standards such as the US AASHTO-LRFD Highway Bridge Design Code (2004) EN1337-3 European standards (2005) and others require suppliers KQGZ seismic steel ball bearings DX, when the annual average temperature and constant loads at all Liang bottom relative levels greater than ask 0.01rad, ball bearing steel must be used to make bridges corner wedge zero level to ensure the bearing seat by force, so our bridge design specifications and bearing industry standards are clearly defined when the beam bottom treatment must be leveling Longitudinal than 1%, while when the two longitudinal less than 1%, when selecting the ball bearing deformation regulations will take into account, this can not be ignored. One end of the beam is not some rubber bearings installed one of these are in the construction is completed to carefully check the contents of the remedy remedy, ball bearing installation steps for the construction, maintenance and other issues laminated rubber bearings This revision row Standard also complemented rubber bearings for the majority of engineering who use and reference. Lastly, I hope the majority of engineering and technical personnel once again, for the selection of bridge rubber bearing, ball bearing bridges and culverts must comply with the requirements of the finished product specifications and industry standards KQGZ seismic steel ball bearings SX, the provisions of these requirements are adequate theoretical basis, the ball Supports and summed up in a large number of experiments on an experimental basis, the application is safe. Ball bearings have not been a lot of experiments to summarize, but only from the standpoint of easy construction and installation using some non-standard laminated rubber bearings. Ball bearings use of millions of careful design parameters apply these bearing plate system that is called circular rubber bearings designed parametric inappropriate, nor with the force characteristics of these bearings, for the larger longitudinal bridge Engineering uses rubber bearings, ball bearings rather increase some trouble in the construction process, the beam bottom leveling, and then you can overcome difficulties processed, ball bearings are not critical to make commitments on the next start The bridge support long-term growth of the most disadvantaged and work force, then to ensure that the practice does not reduce the safety factor of ball bearings.
