Ball bearings and horizontal bearing hinge ball bearing hinge non-slip direction shall not be less than 10% of the vertical bearing capacity, seismic bearing horizontal bearing capacity of not less than 20% vertical bearing capacity, and can withstand not less than vertical to the 20% uplift bearing capacity. Ball bearing hinge is not applicable temperature range, bearing physical and mechanical properties of materials used PTFE sheet, PTFE sheet PTFE sheet bearing use should be made with fresh, pure material molded, not Use cutting boards, you should not use recycled materials Curtain fixed ball bearing hinges, back plates embossed material, poly PTFE sheet material at an average particle size of not greater than 50mm, molding pressure should be less than 30mpa PTFE plate The physical and mechanical properties. Monumental steel ball bearing hinge used, the use of materials such as technical conditions are met adjustable ball joint bearing, tension and compression drink holder designed to be used on the bridge seismic zone basin seismic rubber bearings, spherical bearings and lead pin earthquake rubber bearings, etc., these are almost always the patented product, can be expected in the near future will be the effective use of a fixed bridge engineering ball joint bearing, while monitoring the quality of bridge engineering work has also been strengthened, power ball bearing hinge Experimental study of the performance is also the rise of fixed steel ball bearing hinges to make bridge bearings better meet the needs of our roads and bridges construction. Jacking determine the amount, should be replaced according to the type of bearing is calculated after the rebound is likely to rise from the top of the amount, such as rubber bearings, compressive modulus of elasticity should be calculated in accordance with the holder bearing the traits coefficient allowable value, the ball bearing hinge bearing compression can only be calculated at this time bearing the dead load and live load when subjected to the design adopted under the seismic damping values ??may produce fixed ball bearing hinge and the appropriate value will change whichever is greater as the control of the holder of the most to the total lifting of the control value, the purpose is to control to be able to successfully remove the damaged bearing principle to determine the amount of lifting. Furthermore, the ball bearing hinge when selecting replacement program, in order to avoid damage to the pier at the bone ring girder should be based on the estimated amount of jacking calculated consolidation girder bridge design allowable tensile strength of concrete used As stress control value jacking process, while the ball bearing hinge position to determine the role of Jack, the ball bearing hinge Bin Brigade acting position composite partial pressure of stress, but fraternity ball joint mount to secure local bearing surface type. Step bearing replacement synchronous lifting. Construction preparation.
