[Slide ball bearing steel installation and connection] Either way, the are required to note the following 1. Install embedded positioning plane loaded with structural elevation and whether the size of the design drawings consistency checker at the support and; 2. the bottom surface of the support bearing member concrete strength not less than C30, bearing surface height of not more than four corners 2mm, and the flatness should reach 1/300; 3. [slide] ball bearing steel bearings should be checked prior to installation connection status is normal, not arbitrarily loose and disassemble temporary factory fixtures; 4. welded connections should be checked between the embedded steel and bearing steel before construction of weldability and welding materials and welding technology. There is a gap between the stand and not be embedded steel. If the gap before welding steel ball bearing seismic grid, grouting approach should be taken to fill the post. 5. Supports the use of anchor bolt connections, the bearing surface shall be reserved for anchor holes. Reserved anchor hole center and diagonal position deviation of not more than plus or minus 1mm. 6. [slide] ball bearing steel installation should note the following: ① in upper and lower parts of the bearing structure placed to draw the centerline position on the top and bottom labels bearing centerline to ensure support during installation seat center line of the upper and lower structure parallel to the centerline. The center line of a one-way or two-way sliding bearings sliding bearing sliding direction should coincide, the angle of not more than 5 points. Shall the loose, temporary fixing means lower bearing plate factory, and one shall be arbitrarily when ② bearing mounting and dismounting bearings, seismic steel ball bearings, in order to prevent the occurrence of excessive bearing structure corner which led to capsize. Steel ball bearing slide member to fill the main board of tetrafluoroethylene, without grease lubrication. Although PTFE friction coefficient is more than pure PTFE, but because China is a country of many earthquakes, mounts withstand the horizontal forces from seismic force control, the friction coefficient of PTFE slide not control factor. It can also be divided into fixed and movable type. Seismic tongue disposed in the lower center of the bridge interface. Extending in a short steel box beam, inserted into the piers of steel box, filling high damping material between two steel boxes, to cause buffer damping effect. Seismic tenon also divided into fixed and movable two, stationary seismic joints in steel box along with a leaf spring along the bridge, used to increase the longitudinal stiffness of the seismic joints, and provide some bearings after the earthquake reset capability. High-speed rail bridge were powered by two-span continuous beam, steel ball bearings arranged sliding bearings and laminated rubber bearing mix of fashion, in a continuous beam fixed pier located pot rubber bearings and laminated rubber bearing, steel ball slip earthquake holder for carrying the horizontal beam of the force, set up laminated rubber bearings on both side pier, seismic steel ball bearings SX, can meet the needs of displacement of the beam. Improve utilization - due to the small slide ball bearing steel column section size, compared with the concrete pillars, about 50 percent smaller than a cross-sectional, and flexible bay size, which will increase by 6% to 8% of the effective use of space, but also to achieve free interior space division. Promote the development of supporting industries - steel residential development will be driven by high-quality, high performance of new building materials occur, it will promote the new wall materials, new windows and doors and supporting the development of new products and other environmentally friendly building materials industry. Seismic steel ball bearings GD, Ice manufacturers offer, seismic steel ball bearings provided by the Hengshui-Engineering Rubber Co., Ltd.. Hengshui-Engineering Rubber Co., Ltd.
