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 is small, it may happen lateral bending and torsional buckling lose overall stability [2]. For composite beams, the web or flange when relatively thin, but also may occur in the compression zone of local instability and destruction. So slide ball bearing hinge hinge horizontal sliding bearing, steel beams should be fully taken into account when designing 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 can eliminate compression of an elastic hinge arch, stress and temperature changes caused by the displacement of foundation settlement, while the reinforced concrete hinge hinge cheaper than metal, construction is relatively easy and does not require special conservation . 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 steel hinge with horizontal sliding bearings, but also a lot in the case of being 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] PQXZ ball bearing hinge bearing PQXZ pull tension and compression pressure bearing basin spherical rubber bearing tension and compression in the upper and lower structural steel gusset plate design can withstand the pressure to achieve the bear can pull force from Hebei Hengshui Guangrun Engineering Rubber Co., Ltd. specializes in the development and production of tension and compression PQXZ tension and compression ball bearing basin rubber bearing products. Which hinged truss with vertical sliding bearings, PQXZ-7000kn is pull one pot spherical bearing pressure is bearing roof, steel liner plate and the bottom are a casting basin (made of ZG230-450), the holder Design of vertical bearing capacity of 7000kn, the pulling force of 3070kn bridge with vertical sliding hinge mount, horizontal carrying capacity 5860kn, allow corner for 0.02rad; installation, bearing top, bottom and upper and lower cross member using welding mouth ; PQXZ basin tension and compression rubber ball bearing, to be applied in practice, and achieved good results. [Slide] ball bearing hinge design in steel support usually use the support to improve the stability of the structure or component. Reasonable layout support system can effectively optimize the distribution of the main load-bearing member forces, which can effectively improve the overall stiffness of the distribution, the strengthening of the structure of the weak links, so that the whole structure together to resist horizontal loads, especially earthquakes. Support system designed to comply with the following general principles: [Slide ball bearing hinge support] tension and compression, also known as negative reaction force bearing, can bear negative reaction force bearing, and can be divided into tension and tension rod bearing hinge support categories. Rally hinge support activities can be divided into two kinds of fixed, fixed hinge bearing seat is anchored to the rock bottom end of the beam, fixed on the pier next shake seat top or desk top surface, using steel pins between them connected together; shake seat fixed on the pier between the top surface or desk top surface of the movable block anti-pull down, and the next seat set below the rollers, it can not only withstand the tension, but also along the bridge longitudinal movement of the movable carriage.
