Seismic ball bearing hinge [] KTQZ series 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; reference to a ball bearing design method specified European standard EN1337; 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 metal spraying and heavy-duty coating system, better adapted to the acidic atmosphere, oceans and other corrosive environment. [Seismic] ball hinge support technical performance [earthquake] vertical bearing capacity of the ball joint bearing 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 seat angle is 0.02rad. 4.3 holder can withstand a horizontal force to each fixed bearing GD, DX-way movable bearing transverse direction (along the bridge to be placed) or along the bridge (transverse to the place) is bearing vertical bearing capacity of 15% (seven degrees for earthquake zones) and 30% (for the octave earthquake zone); [seismic] SX-way ball bearing hinge bearing activities because they do not bear the horizontal force finished ball joint bearing grid at reasonable prices! Therefore both for the earthquake zone seven times, but also for octave earthquake zone. The series bearing seven degrees seismic zone seismic peak ground acceleration take 0.10g, octave seismic zone seismic peak ground acceleration take 0.20g; steel ball joint holder] [seismic development and installation of steel as a modern "green building" , because of its light weight, short construction period, fast return on investment, easy to install, seismic performance, less environmental pollution, and other characteristics are widely used in residential, plant office, business, sports and exhibition buildings, and developed rapidly. And how will the steel structure to ensure the quality standards, meet the performance in the case of green construction, to achieve environmental protection, it is the construction industry each person must have a profound thought. Seismic ball bearing hinge [] Installation Notes: 1 [the earthquake] is generally used as a ball joint bearing bearing activities, should be used as a fixed support of ordinary laminated rubber bearings supporting the use. 2. [seismic] and press the ball joint bearing design support center exactly in place, the installation must be carefully detailed. Beam bottom plate and the support cushion stone (or lower plate) parallel to the top surface and smooth as possible, to ensure that the seat is completely snug below; with a respective bearing beams on the same plane should again; avoid bearing appear ECCENTRIC pressure, uneven support and void phenomenon. Specific construction methods and ordinary laminated rubber same. 3. [seismic] professional-quality ball bearing hinge ball joint bearing fixed after installation if a problem needs to be adjusted when!, The general practice is from the top end of the beam, and the bottom surface of the seat cushion and support the stone (lower plate) between ball bearing hinge, can spread coat epoxy mortar to adjust. 4. For slope bridge, that is, when there is longitudinal beam, the specification requirements should take measures to make seismic bearings and ball joints stainless steel contact surface remains level. Such as the use made of the beam at the end of embedded plate corresponding to the slope of the wedge when adjusted longitudinal.
