Slide ball bearing hinge mechanical properties of steel beam steel beam under transverse loads its axis of symmetry plane, generally only produce moments, shear and deflection in the plane. However, due to the cross-section steel beam is usually high, narrow beam, or trough, lateral bending stiffness and torsional rigidity less elastic sliding hinge bearings may also lose the overall stability of the occurrence of lateral bending torsional buckling [2 ]. For composite beams, the web or flange when relatively thin, but also may occur in the compression zone of local instability and destruction. Slide ball bearing hinge, therefore, should be fully taken into account when designing the steel beam and were checking their bending stress and shear strength, deflection, overall stability and local stability. Sliding ball joints such as the three-hinged arch bearing species hinges can eliminate compression by arch flexibility, temperature changes and stress steel foundation settlement displacement caused by the elastic hinge bearing slide, while the reinforced concrete hinges cheaper than metal hinge construction also more convenient, and does not require special maintenance. Slide ball bearing hinge design of reinforced concrete in addition to the factors, the effect of the hinge good or bad, depends largely on the detail treatment of its construction. Due to unreasonable construction process sliding ball joint bearing hinge, is not ideal, but the example often lead to structural damage exists. Because concrete hinge has its unique advantages, all at home and abroad have a lot of engineering and technical personnel of the long-term comparison and analysis, made a lot of good advice and design. Slide ball bearing hinge hinge common type of concrete reinforced concrete hinge according to its structural form, there are a variety of types of hinge, in the case of a lot to be used on various occasions. According to Qi unidirectional rotating rotation requirements and bi-directional rotation of the points. According to the information, some of the commonly used reinforced concrete hinges largely providers can be summarized into the following categories. [Slide] KQGZ ball bearing hinge Seismic Isolation Spherical Bearings adapt to the temperature range is large (-40 to +70 degrees) grid elastic sliding hinge support prices, due to non-rubber bearing structural truss sliding elastic hinge support, without the presence of the impact of aging on the rubber bearing rotation 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 structure with tensile properties, and can be used as tension and compression mount use.
