Slide ball bearing hinge under vertical loads, the vertical displacement of steel beams generally produced only multi-directional slide ball bearing production for advice, but poor lateral stiffness -shaped cross section or channel section steel beams, when greater freedom length of the beam, the load increased to a certain extent, often quickly produce a greater lateral displacement and torsional deformation, so that the loss of the carrying capacity of the beam then the phenomenon known as loss of overall stability or lateral-torsional buckling. When flexural specimens, the same as a simple tensile test according to the test, the general low-carbon and low-alloy steel ball bearing slide GB finished, there are yield strength and yield level, regarded as ideal elastic plastic body. Sliding bearings and ball joints in the elastic range than assumed curved members still meet the plane when the flexural strain. Therefore, under static load, steel beams bent stress can be divided into three phases. 1. Slide the ball bearing hinge Metz Sonoco (Mesnager) hinge Metz Sonoco (Mesnager) hinge design is reinforced through common hinge neck pad, reinforced with cement mortar to protect or concrete to prevent rebar rust, but does not consider strengthening the role of the hinge reinforcement. In order to obtain good bendability, researchers suggest the hinge pad clearance at least equal to the thickness of the portion of the length of the concrete pad. Meanwhile, the Ministry of choice through the reinforced steel hinges not too chunky, not too thin, otherwise easily distorted. 2. Slide the ball bearing hinges Fred Sinai (Frdyssinet) hinges Fred Sinai (Frdyssinet) hinge in little or no reinforcement through the neck, while the main consideration taken to improve the times to withstand the compressive strength of concrete compressive stress method . In a centralized pressure hinge neck tension caused by the transverse component of the use of the nearby steel grid layout to bear, they arranged a distance, starting from the neck width is equal on both sides of members, reinforced grid layout. Now highway bridge bearings are mainly used where? For example, Beijing TV storey 234 meters, just slide the ball joint bearing steel [body part] 120,000 tons of steel, we build aircraft carriers will not take so much, the Shanghai Tower is being built steel structures. Dubai has built more than 700 meters of the high-rise has not capped, for fear others over it, including South Korea also cover 700 meters tall, all steel construction. Now plant basically steel structures. Bridges is the fastest growing steel industry, the Beijing-Shanghai high-speed railway being built bridges, roads and railways as well as for Yangtze river bridge main span of 336 meters. [Slide] ball bearing hinge can be said of being a bridge from the bridge power to power forward. Then is the airport, are also steel construction. Beijing, Kunming, Wuhan, Guangzhou airport in additional two-way slide ball bearing high quality, after the Games, including Shanghai World Expo and Guangzhou Asian Games, National Games in Jinan, Inner Mongolia's national Olympic Games are now built center, gymnasium, Stadium, Aquatics Centre, the construction of cultural and sports facilities everywhere. These are the use of steel structures. Steel national investment, the government invested more. [Slide] bearing factory ball joints, the general should be clearly marked, indicating the bearing type, tonnage and displacement of the reaction force, in order to avoid confusion during installation. Bearing factory to comply with all relevant industry standards. Bridge support structure is an important component to connect the upper and lower part of the structure, ready to pass the upper structure of the reaction force to the lower part of the structure, it has to adapt to the lower structure and function of displacement should be assigned the horizontal force and adapt to the beam end corner deformation. Further, bearing structure to ensure safety, it is necessary to have to adapt their useful life durability.
