Embodiment 1
[0054] See Figure 1 to Figure 5 , The special-shaped three-dimensional seismic isolation support of the present invention is arranged between the upper and lower structures that need to be isolated, and includes:
[0055] A bottom plate (6) is connected to the lower structure; at least two special-shaped supports (4) are composed of parallel upper and lower sealing plates sandwiching the first elastic block; the upper connecting corner block and the lower connecting corner block (3 and 5) It has a horizontal bottom surface and an inclined top surface, and when the upper connecting corner block is inverted and the lower connecting corner block is superimposed, the bottom surfaces of the two are parallel; a horizontal support (1), the second elastic block is sandwiched by the upper and lower plates Composition; a sliding panel (2); the upper connecting corner block (3) is connected with the special-shaped support (4) and the lower connecting corner block (5) in an upside down posi...
Embodiment 2
[0060] See Image 6 with Figure 7 The difference between the second embodiment and the first embodiment is that the special-shaped support is pre-deformed and the upper connecting corner block (3) is connected upside down with the special-shaped support (4) and the lower connecting corner block (5). Together, the special-shaped support (4) is placed obliquely with respect to the contact slope with the upper and lower connecting corner blocks, the three are in a vertical state, and the special-shaped three-dimensional seismic isolation support has a regular cylindrical space structure as a whole. The pre-deformation treatment enhances the deformability of the special-shaped three-dimensional seismic isolation support.
[0061] When the special-shaped support (4) is not pre-deformed, its shape is a space-wound structure; after the special-shaped support (4) is pre-deformed, its shape is a regular cylindrical space structure.
Embodiment 3
[0063] See Figure 8 , Picture 9 , Picture 10 with Picture 11 The difference between the third embodiment and the second embodiment is that for the special-shaped support 4 adopting the pre-deformation treatment, a vertical tubular sleeve 9 is fixed on the center of the bottom plate (6), and a cylindrical rotating guide 8 is inserted therein. The upper end of the rotating guide rail 8 passes through the central hole opened by the sliding panel 2 and then abuts below the horizontal support 1. The contact surfaces of the rotating guide 8 with the horizontal support 1 and the sliding panel 2 are made of friction materials, and the friction coefficient is within a certain range Change, while rotating the damping material between the guide rail 8 and the sleeve 9. The combined structure of the rotating guide rail (8) and the sleeve (9) acts as a horizontal limit for the special-shaped support (4), and a damping material can be placed between the rotating guide rail (8) and the sle...
