[Slide] ball bearing hinge bearing laminated rubber tension and compression is designed to pull a ball joint mount screws KZ seismic homegrown manufacturers at the center of the laminated rubber bearing, the bearing plate roof and fell together. In order to meet the vertical sliding bearings, and bearing between the plate and the bottom plate and anchor slipped set stainless steel gusset plates and PTFE slide. Section design] [slide ball bearing hinge section design is reasonable directly related to the safety of the structure, cost and convenience of construction projects. After the structure is determined, you can make a preliminary estimate of the member section based on experience. Including assumptions beams, columns and other components to support cross-sectional shapes and sizes, usually steel beams selectable channels, rolled or welded h beam cross section and so on. According to the case load and bearing ball bearing hinges, the section height is usually a choice between 1/20 ~ 1/50 span. According to China's current steel flange width specification limits determined by the beam spacing between lateral support, try to avoid the calculation of the overall stability of steel beams. Determine the cross-sectional height and flange width, its plate thickness according to the specification of the structure of local stability to preliminary determination. Column section slenderness ratio according to estimates usually 50≤λ≤80, then consider the different stress situation, choose section in the form of steel and other steel or h. [Slide ball bearing hinge tension and compression] pot pot holder bearing tension and compression, usually achieved through a fixed pot bearing center wearing a prestressed reinforcement (prestressed anchor) approach. Prestressed prestressing steel shall be 1.2 times the pulling force to ensure seat not because of bolt elongation disengaged. Prestressed anchor rotation axis can also be set in the pot bearings on both sides, and for pot bearings bearing activities, prestressed rod can only be set on both sides of the shaft bearing. By prestressing steel fixed support center in the seat height range should be equipped with a closed casing to form a rotating seat cushion to make the buffer layer. [Slide] KQGZ ball bearing hinge Seismic Isolation Spherical Bearings adapt to the temperature range is large (-40 to +70 degrees), due to the structure of high-quality non-slip rubber bearing ball bearing hinge, without the presence of rubber bearings rotate on aging affect performance, and therefore better durability. Steel sliding ball joint bearing stable [] in detail the design and construction elements of the calculation should be consistent to ensure the stability of the detailed structure of steel and component design calculations consistent, is the height of the steel structure design needs attention. Requirements for passing moments and moments of connection node does not pass, it should be endowed with sufficient rigidity and flexibility of the truss rod should minimize eccentric respectively. [Slide ball bearing hinge] However, when it comes to performance and stability, there are often different from the strength requirements or special consideration on the structure. For example, Charpy on flexural strength, it does not move hinged bearing on the requirements merely prevent displacement, while allowing rotation in the plane. However, the overall stability of the beam when addressing the above requirements is not enough, the seat needs to be able to prevent the beam around the longitudinal axis of the torsion beam while allowing freedom of rotation and the beam end section warping in the plane to meet the stability analysis of boundary conditions taken. [Slide] KQGZ seismic ball bearing hinge ball bearings suitable for a wide bridge, curved bridge, bridge, ramps and bridges large bridges span space structural engineering, especially in bridge engineering applications of high intensity seismic zone is more applicable . KQGZ spherical bearing is a kind of seismic structural seismic KZ universal ball joint bearing professional supply has tensile properties, and can be used as tension and compression mount use. Seismic Isolation Spherical Bearings KQGZ existing series of product specifications, for different customer choice.
