PTFE sliding plate rubber support
PTFE sliding plate rubber support is also called PTFE slide bearings, such as (GJZF4, GYZF4), it is the Teflon plate 1.5mm-3mm thick layer on the surface of viscoelastic laminated rubber bearings.
GJZF4 GYZF4, PTFE sliding plate rubber support PTFE sliding plate rubber support: PTFE sliding plate rubber support is also called PTFE slide bearings, such as (GJZF4, GYZF4 Series), poly tetrafluoroethylene plate is stuck to the surface of the rubber bearing complex layer of 1.5mm-3mm thick. As a result of the Teflon sliding friction coefficient between the beam bottom stainless steel plate is very low, the horizontal displacement of the upper structure of the bridge, from the bridge bearing itself shear deformation limit, it can meet the needs of large displacement bridge. This product has the function of spherical bearings, especially for large displacement bridge. The product characteristics of PTFE laminated rubber bearing has the advantages of simple structure, low cost, no maintenance, easy replacement of shockproof, low building height, this product in 1996 by the Chongqing Municipal Technical Supervision Bureau Inspection and put into production, so in the bridge area is very popular, widely used. PTFE sliding plate rubber support for use: 1, according to the Ministry of Transportation Division Series JT\T4-93 specifications. Can support the activities to use: mainly used in large span bridge beam span of 30 meters. The continuous slab bridge, multi span continuous beam bridge. 2, as the slider block, the surface of the PTFE plate thickness is divided into 1.5 mm, 2 mm, 3 mm and other continuous beam pushing, T beam transverse movement, large equipment slippage. 3, special specifications can be negotiated production by users. The load grade of PTFE plate rubber bearing is divided into 100KN-10000KN, and the bottom plate and stainless steel plate can be supplied. 4, chloroprene rubber type: +60 ~ 25, 2, natural rubber type: +60 ~ --40, 3, three ethylene propylene rubber type: +60 ~ -45
