Finished fixed ball bearing hinge, universal rotation pin hinge, steel hinge support

    Seismic design and manufacture of ball bearing hinge principle, even regular shape, both in plane or facade structure layout, have sought to make geometry, stiffness regular uniform ductility, increasing the strength and ductility of the structure and components.
    [Universal ball hinge support] finished fixing ball bearing hinges, universal rotation pin hinge, steel hinge bearing, bearing steel truss, steel seismic ball bearing hinges, gymnasium seismic steel ball bearings
    Seismic ball bearing hinge series seismic tension and compression mount includes a fixed bearing, one-way bearing activities, three types of two-way bearing activities, bearing specifications are divided into 22 grades, vertical design bearing capacity, design corner friction coefficient according to the relevant design standards. Their level of capacity, the overall strength of the vertical pulling force than ordinary bearings and bearing a substantial increase. The series bearing elastic damping element, with a clear mechanism of clear, stable structure parameters, excellent damping performance characteristics. The family seat is suitable for large-span spatial structure and large span slab, especially for highly seismic areas of engineering structures.
    A seismic ball bearing hinge design and manufacturing principles
    Regular uniform shape, both in plane or facade structure layout, have sought to make geometry, stiffness regular uniform ductility, increasing the strength and ductility of the structure and components.
    Multi-channel vibration defense.
    Prevent brittle and unstable failure.
    Prevent material aging.
    High-quality manufacturing and installation.
    Second, the seismic performance of the ball bearing hinge parameter index
    Vertical Bearing Capacity: 500-80000KN
    Vertical pulling force: 500-80000KN
    Horizontal Shear: 500-80000KN
    These three types of force can be used to select the appropriate combination, but in special circumstances to be subject to review designs.
