Embodiment 1
[0048] A prefabricated cantilever frame horizontal and vertical multi-dimensional isolation energy dissipation system, such as Figure 1 to Figure 11 As shown, it includes a horizontal vibration isolation subsystem 1 and a vertical vibration isolation subsystem 2. The horizontal vibration isolation subsystem 1 includes a shape memory alloy (hereinafter referred to as SMA) coil spring limiter 11, a horizontal sliding support and a connecting piece 12 ; The SMA coil spring limiter 11 is connected between the support structure or the top of the foundation 3 and the bottom of the superstructure 5 through the connector 12, and is arranged radially and evenly in a circumferential direction; the sliding support includes a slider 21 and a horizontal sliding track 29, The horizontal slide track 29 is fixedly installed on the bottom of the superstructure 5, and the slide block 21 is in contact with the horizontal slide track 29 to form a horizontal sliding shock isolation mechanism, so t...
Embodiment 21
[0065] A prefabricated cantilever frame horizontal and vertical multi-dimensional shock-isolation and energy-dissipating system is different from Embodiment 1 in that both the SMA rod 24 and the SMA coil spring are large-sized SMAs with a diameter of 12 mm.
Embodiment 22
[0067] A prefabricated cantilever frame horizontal and vertical multi-dimensional shock-isolation energy-dissipating system is different from Embodiment 1 in that both the SMA rod 24 and the SMA coil spring are large-sized SMAs with a diameter of 14mm.
