example 1
[0042] See figure 1 , The three-dimensional seismic isolation support in this example is composed of a laminated rubber seismic isolation support and a vertical seismic isolation support connected in series.
[0043] See figure 1 with Figure 4 , The laminated rubber shock isolation support includes an upper connecting plate 14, a lower connecting plate 15, a laminated rubber pad 17 clamped between the upper and lower connecting plates, and six tensile steel cables 16; wherein, the upper The connecting plate 14 and the lower connecting plate 15 are both disc-shaped, and the edge of the upper connecting plate 14 is provided with mounting holes 13; the main body of the laminated rubber pad 17 is made up of a layer of rubber 17-1 and a layer of steel plate 17-2 alternately After being laminated, it is formed by compression and vulcanization, and a rubber protective layer 17-3 is naturally formed around it during the compression and vulcanization process. The upper and lower end fa...
example 2
[0056] This example has the following differences from Example 1:
[0057] See Figure 8-10 Both the first group of pre-compressed steel cables 8 and the second group of pre-compressed steel cables 9 are composed of three pre-compressed steel cables.
[0058] See Figure 8-10 , The upper end of the first group of pre-compressed steel cables 8 and the lower end of the second group of pre-compressed steel cables 9 are respectively fixed on the driving plate 5 and the base by using a steel cable self-locking anchor 19 instead of the eyebolts in Example 1. 3; In this example, the middle of the base 3 needs to be thickened and raised upward to form an inverted washbasin, so as to facilitate the installation of the wire rope self-locking anchor 19.
[0059] See Figure 11~13 And combine Figure 7 , The steel cable self-locking anchor 19 is composed of a mounting hole provided on a mounting plate 19-1, a clamping jaw 19-2 and an anti-loosening bolt 19-4, wherein the mounting plate 19-1 is t...
example 3
[0063] See Figure 14-16 The difference between this example and Example 2 is that the first group of pre-compressed steel cables 8 and the second group of pre-compressed steel cables 9 are both composed of five pre-compressed steel cables.
[0064] Embodiments other than the above in this example are the same as in Example 2.
