Hao-engineering rubber, rubber bearing gjzf4, rubber bearings supplied by Hao-engineering rubber. We are Hengshui HaoTong Engineering Rubber Co., Ltd. (www.htgcxj.com) located at: Hebei Hengshui specializes in: grid bearings, bridge expansion joints, water stop, bridge bearings, rubber bearings, spherical bearings by structural steel bearing weight bearing reaction force due to the standard value of 0.5 times the vehicle load (included in the impact factor) bearing reaction force due to the standard value; see Section 8.4.2 specification JTG D62-2004, but excluding automobile braking force caused by shear deformation, the plane bearing gross area, the standard values ??braking force caused by the car load. PTFE slide rubber bearing friction coefficient should meet the following requirements in some of them. The design calculation example in order to help readers understand the bridge design specifications of the relevant provisions "of reinforced concrete and prestressed concrete highway bridge design specifications" (JTG D62-2004), basically in accordance with the provisions of the order specification requirements. Basic data design (according to the specification section 8.4.1) of the use of the seat installed in the warm area, so the concrete abutment contact at room temperature, the friction coefficient σ = 0.3; bearing an average compressive stress of 10mpa. A laminated rubber bearing role (or load) effect standard value rubber bearings gjzf4, weight bearing reaction force for 380kn, vehicle load reaction force for 290kn, weight and vehicle load reaction force for 670kn, temperature drop, concrete shrinkage and bearing shear deformation caused by creep 16.5, automotive braking force for 3.2kn rubber bearings, bearing directly located at 0.5% below the bottom longitudinal beam, along the longitudinal direction of the reaction force is divided into: weight and vehicle load gpz rubber bearings, weight deflection at the fulcrum of inclination φ = 0.0023rad, bearing top surface generated by the longitudinal beam angle position φ = 0.005rad, laminated rubber bearing geometry and mechanical properties. Supports use of 250mm * 300mm * 63mm rectangular laminated rubber bearing rubber bearing gyz200, single rubber thickness of 8mm, total rubber layer is 45mm, bearing steel stiffening short side length of 240mm, bearing stiffened plate length 290mm, hair flat area of ??75000mm, bearing capacity factor of production compressive model. Coordination of the so-called seat and the environment, the impact due to causes bearing on the surrounding environment. For example, due to the impact of bearing vibration generated traffic, bearing the appearance to the landscape, such as the impact should be considered, bearing the economy can not just consider the minimum initial investment costs, but should include inspection management, repair and replacement Low maintenance and management costs were considered. To truly achieve the above functions and role should choose the rational design, manufacturing high quality precision bearings, while the right to do all aspects of construction and installation as well as maintenance and other recurring is the reliable guarantee. Bridge bearing the functional classification of bridge bearings main features additional functions into the basic functions of families, earthquake (including vibration control function), and vibration control functions can be divided according to the needs of individual functions and complex functions, the main function will be bearing induction.
