Supply Baoji GYZF4 tetrafluoroethylene laminated rubber bearings

 This product can be divided into: general type plate bearing and bearing two cold-type plate. One common type of plastic material into the surface using neoprene formulation, used under temperature -25 ℃ ~ + 60 ℃. Cold-type compound formulated with natural rubber, used at a temperature of -40 ℃ ~ + 60 ℃. After 2009, the state proposed to stimulate domestic demand, so that China's high-speed railway passenger line in the period of construction, especially in the winter cold box girder erection during install bridge bearings, often becomes a node control construction progress, and in this process, how to bearing construction quality control at a low temperature environment has become the difficulties of construction. Through the study of the stiffness characteristics of the railway plate bearing the fixed mode, pier stiffness, mass and other structural parameters in response to the impact of the bridge dynamic analysis and comparison of the mechanism developed under the train bridge load dynamic response, affecting the way, features and laws. Tetrafluoroethylene laminated rubber bearing (GJZF4, GYZF4 series), is in the ordinary laminated rubber bearing a thick sticky complex 2-3mm Teflon plates together. PTFE slide mount except vertical stiffness and elastic deformation of ordinary laminated rubber bearing, and can withstand the vertical load and adapt to the beam end rotation, the use of low friction coefficient PTFE plate and stainless steel plate between (μf≤ 0.08) allows the horizontal displacement of the upper bridge construction unrestricted. Span> .30 meters long-span bridges, Charpy Itabashi continuous and multi-span continuous girder bridge bearing activities can make use; push continuous beam, T-beam traversing the slip can be used for large-scale equipment and use the slider. Tetrafluoroethylene rubber plate bearing in the top surface of the paste layer laminated rubber bearing PTFE plate plane with equal size, set a stainless steel plate in the bottom surface of the beam to do with the relative sliding movement. This is the advantage of the relative motion between the friction coefficient is very small features Teflon and stainless steel, making it active support. In addition it has the advantage of laminated rubber bearing, but also meet the requirements of a large amount of horizontal displacement. Thus suitable for large-span simply supported beam and continuous beam and continuous bridge deck. Tetrafluoroethylene skateboard rubber bearing is divided into two types of closed and Simple. For urban bridges and ultraviolet radiation, air pollution and dust severely affected areas, should be closed, and the rest can be employed Simple. Tetrafluoroethylene skateboard rubber bearing type, height should be determined according to the actual size of the displacement and the support reaction force
