First, the introduction of products
Railway basin type rubber bearing consists of an upper base plate, a bottom plate, the middle plate, rubber bearing plate, copper seal, rubber seals, PTFE, SF-1B composite plate, stainless steel plate and other components. The structure and common pot rubber bearing structure, has a good guiding and limiting performance that is suitable for railway simply supported T beam, simply supported beam and continuous beam.
Two, product features
1 the pressure rubber plate in the bottom of the basin is in a three phase constraint state, the energy absorption of the rubber, the energy dissipation function is fully played, and has the advantages of large bearing capacity, shock absorption, and obvious isolation effect;
2) the rotation angle of the support vertical curve is 0.02rad, and at the same time, the rotation of the horizontal curve is flexible;
3) one-way movable bearing sliding friction pair made of stainless steel and SF-1B composite plate has a good guiding and limiting performance, the orientation gap can be accurately controlled, to ensure the stability limit of beam orientation;
4) the dust proof device adopts the combination of the industrial rubber plate and the support plate to ensure that the environment is clean and has no pollution and interference;
5 the upper and lower seat plate exposed parts using precision casting molding, not mechanical processing, is conducive to increase the adhesion of anti-corrosion coating, to extend the anti-corrosion life, but also reduce the amount of steel and manufacturing cost, significant economic benefits;
6) seat board top preset 0 per thousand to 20 per thousand in slope, in order to meet the needs of precast beam slope, simplifies the bearing installation and construction difficulty, improve construction efficiency, convenient for engineering quality control;
7) bearing friction coefficient is less than 0.03, with the use of lubricating grease, which greatly improves the bearing life;
8) ambient temperature range of application (-40 C ~ +60 C), can be widely used in the region.
Three, product application
Railway basin rubber support strict implementation of People's Republic of China railway industry standard TB/T2331-2013< railway bridge basin type rubber bearing >, railway construction letter  No. 285 railway bridge design of the Interim Provisions on the standards of R & D products, components of seismic design code for Railway Engineering > GB50111-2006< regulations and relevant industry standards.
The Joint Design Institute of railway science technology company, has transformed with TPZB (I, II, III, IV, V, VI, VII, VIII) type railway bridge basin type rubber bearing series, suitable for passenger and freight bridge and light rail bridge.
The company obtained the CRCC railway passenger and Freight Bearing certification, TPZB type railway pot rubber bearing has been Xibao passenger dedicated railway, Shijiazhuang Taiyuan Passenger Dedicated Line, Hefei Wuhan railway, Wenzhou Fuzhou railway, Beijing-Shanghai high-speed railway, Rongcheng line and other major domestic railway projects.
