1, according to the structure type bridge laminated rubber bearings are classified as follows: Ordinary laminated rubber bearing --- spherical cap round laminated rubber bearing (TCYB series) ,; rectangle ordinary laminated rubber bearing (GJZ series; round ordinary laminated rubber Supports (GYZ series) PTFE laminated rubber bearings ---- round tetrafluoroethylene laminated rubber bearing (GYZF4 series); rectangular tetrafluoroethylene laminated rubber bearing (GJZF4 series) tetrafluoroethylene laminated rubber bearing spherical cap (TCYBF4 series) 2, laminated rubber bearings by plastic types applicable temperature classification as follows: a, neoprene: Temperature + 60 ℃ ∽-25 ℃ b, natural rubber: Temperature + 60 ℃ ∽-40 ℃ c, three Ethylene-propylene rubber: Temperature + 60 ℃ ∽-45 ℃ look forward to sincere cooperation with you, if necessary, contact the image above contact numbers laminated rubber bearing surface sticky complex layer 1.5mm-3mm thick PTFE plate Bridge rubber shock pad can be made into rubber bearing bridge rubber cushion sales, also known as: PTFE skateboard bearings (GJZF4, GYZF4 series) In addition to having all the features of GYZ series rubber bearings outside. Teflon plate (F4 board) and low coefficient of friction between the beam bottom stainless steel plate, the upper structure of the horizontal displacement of the rubber cushion, without bearing shear deformation limit itself to meet a number of bridges require large amount of displacement. The laminated rubber bearings in addition to a spherical cap rubber bearing function, but also particularly suitable for large displacement of the bridge. tetrafluoroethylene laminated rubber bearing not only advanced technology, excellent performance, but also has a simple structure, low price ., maintenance-easy to replace the buffer isolation, low building height and therefore popular in bridge circles, is widely used laminated rubber bearings range:. a movable carriage for use: Mainly used span> 30 meters long-span bridges simply supported beam slab bridge, multi-span continuous beam bridge .b. As a slider block pushing continuous beam, T-beam traversing, large equipment slip rubber bearing load rating .F4 into 100KN-10000KN laminated rubber bearing specifications: 1, according to the Ministry of Communications JT \ T4-2004 specifications series .2, surface mount complex PTFE plate thicknesses of 1.5 mm, 2 mm, 3 mm, etc. .3, special specifications made by the user consultation Production .4, beam bottom plate and stainless steel plate can be equipped with supply .5, rubber bearing model and applicable temperature neoprene type:. + 60 ℃ ~ 25 ℃ 2, natural rubber type: + 60 ℃ ~ --40 ℃ 3 EPDM rubber type: + 60 ℃ ~ -45 ℃
