[Seismic] ball hinge support the development and construction of steel since the 1980s, Shanghai universal ball hinge support all models, spatial grid structure common in the hangar, terminal hug, stadiums, high, empty, big (height, space, span) used in buildings; energy-saving windows and doors curtain wall construction and residential construction of large public and widely used; since the reform and opening up and development of high-rise steel (including steel reinforced concrete structures), poured into the field of civil construction, steel making building structure, technically more mature and more stable in terms of quality. Steel housing has brought to the housing industry and the construction industry of a deep-seated revolution, from the design, construction, use of new materials into a series of revolutionary changes have emerged, which in the international context of the future of housing the development of new models. Precast beams [seismic] ball bearing hinge construction sequence and precautions usually can be summarized as follows: 1. Press the cast of [seismic] ball joint bearing pad stone cleaning and adjustments required, pre-deal support cushion stone. 2. precast beam end is not placed [seismic] ball bearing hinge at the bottom of the treatment: the bottom plane of contact with the bearing precast beams shall ensure that the level and smooth, if there should be pre-cellular or tilt tamping with cement mortar, leveling. 3. [seismic] ball bearing hinge in place requirements are properly seated press situ beam will hinge ball bearing [earthquake] in the stone pier pad in place according to the design center position. When falling girder beam, T-beam longitudinal axis should coincide with the bearing centerline; plate girder and box girder should be parallel to the longitudinal axis of the bearing centerline. In order to make accurate off the beam, in the erection of the first inter-plate girder or box girder can be pre-plan a good seat at the end of the cross beam centerline position, and mark the position of the center line of the two bearings at the ends of the beam facade The vertical line Shanghai grid ball bearing hinge price, make off with the pier on the beam position coincides with the center line of the ball bearing hinge, after several cross beams can be according to the first cross-reference beam off. [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 systems Yunnan Earthquake ball bearing hinge trustworthy! More able to adapt to the acidic atmosphere, oceans and other corrosive 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; Shanghai universal ball joint bearing all models | ball bearing hinge | factory new technology built by Hengshui wide Run Rubber Limited. Hengshui Guangrun Engineering Rubber Co. (www.grgcxj.cn) (www.grgcxj.cn) strong, credible, Hebei Hengshui site construction materials industry has accumulated a large number of loyal customers.
