Specific embodiment
To further illustrate the technical scheme of the present invention below with reference to the accompanying drawings and specific embodiments.
As shown in Figure 1, change sliding isolated bearing embodiment of the invention, set on the building structure and base for needing shock insulation
Between plinth comprising: a lower connecting plate 8, be fixed on it is described on the basis of；One sliding panel 7 has horizontal upper plane and fixation
On the lower connecting plate 8；One cyclic annular baffle ring 6, is trapped among and is fixed on the surrounding edge of the upper plane of the sliding panel 7
On；One flexible support 3, bottom is fixed with sliding block 4 and is located on the sliding panel 7 in the centre of plane, top is solid
Surely there is support upper junction plate 2；One upper junction plate 1, top surface are fixed on the building structure bottom, bottom surface and the flexible branch
2 top surface of support upper junction plate of support 3 is fixedly connected；The sliding block 4 rubs with the upper planar central position of the sliding panel 7
Wipe the coefficient of friction that coefficient is higher than itself and upper remaining position of plane.
On the basis of the above, the present invention can also have following various advantageous embodiments: the sliding block 4 is polytetrafluoroethylene (PTFE)
Sliding block.
The upper plane of the cyclic annular baffle ring 6 and the sliding panel 7 is fixed by bolt 5.
