[Slide] ball bearing hinge structure principle disc bearing the American public bridge design specifications and performance requirements of the structural characteristics of the disc holder are made specific provisions, disc qualitative component size should be used in the strength limit state lower ball bearing hinge, when designing the displacement and rotation for the most unfavorable combination, and will not interfere with the structure of hard contact structure further displacement or rotation occurs between the metal components it is to adapt to the rotating bearing by deformation polyetherpolyurethane requirements, [slide ball bearing hinge] (1) a clear, rational transfer vertical loads. (2) to ensure the stability of the structure of the system outside the plane, and the overall stability of the structure to provide lateral pivot member. (3) structure for easy installation. (4) meet the necessary strength and stiffness requirements, a reliable connection. Usually between columns supporting cross type. When studs have transportation, traffic domains, placing equipment, etc., may be used between the gantry between support columns and monoclinic type column support. In addition, herringbone, k-shaped, l-shaped and other forms of support, the support system for the common way how to install a sliding ball joint bearing vibration? Under the same amount of steel, the role of cross-support system and support system to improve the human word lateral stiffness is relatively significant. [Slide] ball bearing hinge bearings have other special tension and compression forces on the pull-type rocker shaft bearing, commonly used on steel bridges, typical design structure node node is designed to connect the entire design process is extremely important part of the node or not properly designed, to ensure the integrity of the structure, reliability and cost of construction period and has a direct impact. Carrying out structural design, structural analysis process node should think what form to use, according to the choice of structural components, power transmission characteristics of the different choice of judge is just a node, or semi-rigid hinge node node. [Slide] KQGZ ball bearing hinge Seismic Isolation Spherical Bearings adapt to the temperature range is large (-40 to +70 degrees), due to non-rubber bearing structure, without affecting the aging of rubber bearing rotation performance exist, so the more durability Okay. 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] but unidirectional sliding ball joint bearing vibration conservation finished, 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 torsion beam about the longitudinal axis unidirectional ball bearing hinges 1000kn, while allowing the beam to rotate freely and warp beam end section in a plane, in order to meet the steady 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 structure with 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. [Slide] DHQZ ball bearing hinge spherical steel bearing is reduced seismic Hengshui Rubber Co. Guangrun bearing well-developed products, such holder longitudinal displacement (ZX) and fixed (GD) two categories.
