[Slide] KQGZ seismic ball bearing hinge ball bearing steel can withstand tensile, compressive, shear (lateral) force, due to the strength and ductility of these bearings is higher than the bridge structure itself strength and ductility, therefore, the use of such support seat at random seismic force, as long as the bridge substructure itself is not destroyed, it will not fall beam, landing gear and other catastrophic consequences. Excellence in quality one-way bearing activities simultaneously, KQGZ spherical bearing ability seismic resistance of 9 degree seismic intensity, it is especially suitable for high-intensity earthquake zone bridge fortification. When [slide] ball bearing hinge structure calculation diagram needs and practical calculation method is based on the schematic design is consistent when single or multi-frame structure, usually not only a stable framework for stability analysis and calculation of the frame column. This approach is used when computing framework COLUMN column length factor, through the framework of the overall stability of the analysis should be drawn so that the column stability calculation is equivalent to the framework of stability calculation. "Steel Design Code" (GB50017-2003) for single or multi-column frame given length factor using five basic assumptions, including: "in the framework of all the columns are simultaneously losing stable steel pot rubber unidirectional movable bearing manufacturer, that while each column reaches its critical load, "according to the stability of the parameters of each column of this assumption, frameworks, common methods rod stability calculation is based on certain simplifying assumptions or typically drawn When designers need to confirm the structure designed to meet these assumptions correct application. [Slide] [slide ball bearing hinge hinge ball bearing] KQGZ earthquake than laminated rubber bearing spherical bearings and pot bearings stiffness, deformation bearing universal joints little cheap rubber bearing activities, Large cars and trains to ensure a smooth shape at high speeds. KQGZ seismic bearings and spherical roller bearings and the rocking shaft bearing joints such as bearings, compared greatly reduced volume and height, light weight, easy installation, the cost is relatively low. [Slide] ball bearing hinge rubber basin basic principles of the basic principles of the load bearing basin rubber bearing force measurement is based on the pot bearing rubber bearing plate under pressure fluid has an approximate nature, rubber uniform distribution of the pressure cell portion, thus forming an oil chamber in the pot bearings rubber, to determine the actual pressure on the carriage and then using an oil chamber of oil pressure variation. [Slide] Since the upper ball joint bearing structural load bearing reaction force size by concrete shrinkage and creep, the combined effect of prestressing loss and other factors. Bearing reaction force at some stage for a test caused by factors can indirectly understand the impact of this factor on the structure. Expected future events based on research on the dynamometer bearing supports, further study the use of bridge bearings to adjust the reaction force statically indeterminate structure, so that the support reactions of the bridge structure more in line with the theoretical value of design to improve the structure stress state. [Slide] ball bearing hinge connecting plate: simply whichever thickness of the beam web thickness plus 4mm, then checking the net Shear and so on. Beam web: net should be checking Shear bolt hole webs, pressure-type high-strength bolted needs local bearing checking the hole wall. Node design must consider the mounting bolts, welding and other construction site space and components, such as lifting the order. Members can not be transported to the site installation is common mistake for beginners. Furthermore, it should as far as possible so that workers can easily locate and temporarily fixed site. Node design should also consider the level of manufacturing processes, such as steel pipe connecting nodes intersecting line of incision CNC machine tools and other equipment needed to complete.
