Main technical performance of one-way sliding anti-seismic spherical hinge bearing
Can carry vertical load
It has the performance of resisting vertical tension to ensure that the upper and lower structures are not disconnected during vertical earthquakes
br/> It has the performance of resisting horizontal force to ensure that the structure will not be disconnected during horizontal earthquakes
It can adapt to the radial and circumferential displacement requirements
It can adapt to the angle requirements in any direction
The shock-absorbing bearing has good Excellent shock absorption performance
The bearing transmits force through the spherical surface without any necking phenomenon, and the reaction force acting on the upper and lower structures is relatively uniform
The bearing does not use rubber to bear pressure, and there is no impact of rubber aging on the bearing. long life.
One-way sliding anti-seismic spherical hinge bearing
Different from ordinary anti-pull spherical hinge bearings, the shock-absorbing anti-pull spherical hinge bearing not only focuses on connection and limiting, but also focuses on the release of force. Protection of the structure during the process. When the support is subjected to an impact load, the buffer device can slow down the impact force and reduce displacement acceleration through flexible contact, thereby protecting the support itself and the main body of the steel structure. Secondly, a stainless steel plate and a polytetrafluoroethylene slide plate are arranged between each relative displacement surface. The relative sliding between the two achieves displacement. This greatly reduces the friction coefficient and allows flexible movement between the components to avoid the occurrence of crawling.

Design parameters and technical performance
The vertical pressure of the bearing is divided into
The vertical pull-out force of the bearing is determined in Within the vertical pressure
The horizontal shear resistance of the bearing is determined within the vertical pressure
The horizontal displacement stiffness of the bearing is/between
The design rotation angle is also based on the actual situation. Corresponding design is done within
The horizontal displacement is designed for fixed shock absorption. The displacement required for different projects can be designed separately
