Embodiment 1
[0030] see Figure 1 to Figure 5 , a separate three-dimensional damping and energy-dissipating seismic isolation bearing, including an upper structure 1, a middle bearing platform 2, a lower foundation bearing platform 3, a horizontal seismic isolation bearing 4, an upper friction plate 5, a lower friction plate 6, and a horizontal limit Block 7, connecting corner block 8, vertical shock-isolation support 9; the superstructure 1 is connected with the horizontal shock-isolation support 3 by bolts; the horizontal shock-isolation support 3 is fixed on the middle bearing platform 2; the middle bearing platform 2. It is fixedly connected with the upper friction plate 5; the upper friction plate 5 is in contact with the lower friction plate 6 and can slide freely; the connecting corner block 8 is a triangular prism, which is fixedly connected with the lower friction plate 6 and the vertical vibration isolation support respectively 9. The vertical shock-isolation support 9 is fixed o...
Embodiment 2
[0034] This embodiment is basically the same as Embodiment 1, and the special features are as follows: Image 6 As shown, three vertical shock-isolation supports 9 are used in this embodiment, and their horizontal positions are arranged symmetrically to the center to form a group of spatially symmetrical outwardly expanding cylindrical structures. The vertical vibration isolation bearing 9 adopts lead core rubber bearing, and every two vertical vibration isolation bearings 9 are in the shape of "eight" with the horizontal line, and are placed obliquely at the same angle, and the inclination angle is according to the vertical The vertical displacement required for the load and vibration isolation is calculated and determined, and adjusted between 0°-90°; when subjected to vertical pressure, the upper friction plate 5 and the lower friction plate 6 undergo a symmetrical outward expansion relative sliding, and the vertical isolation The shock bearing 9 undergoes compression-shear...
