The coating thickness was 2mm and the refractory limit time was measured to be 63 minutes.

In the present embodiment, as a preferable mode, a detailed description is given of a shock absorbing system, however, the invention discloses a shock-absorbing system which comprises any two or more than two of the shape memory alloy stranded wire support shock absorber, an assembled buckling-restrained support, an annular shape memory alloy spring omnibearing shock-absorbing support, a combined shock-absorbing support and an X-shaped energy dissipation shock-absorbing support, wherein two or more shock-absorbing devices in the combination are installed in parallel, and the two shock-absorbing devices are jointly installed in parallel to form the shock-absorbing system, and belongs to the shock-absorbing system of the invention, in particular, the preferred embodiment discloses a shock-absorbing device for superposing bidirectional shock, which comprises two groups of shock-absorbing supports, namely a first shock-absorbing support and a second shock-absorbing support, wherein the first shock-absorbing support is directly contacted with and fixedly connected with the second shock-absorbing, the first isolation bearing is positioned above the second isolation bearing or the first isolation bearing and the second isolation bearing are arranged side by side.

The annular shape memory alloy spring omnibearing shock insulation support is specifically referred to as the shock insulation support in embodiment 3. For the device with two-direction shock absorption, the single device can simply increase the length of the spring to increase the energy consumption level (namely the influence of the energy consumption of the spring) on the compression and the extension of the spring, but the single device is not ideal, the length of the spring is increased to a certain range, and the energy consumption strength cannot be greatly increased, so that the synergistic use of the two combinations is considered, and the energy consumption effect is better compared with the scheme of simply increasing the length of the spring. This scheme has solved the problem that simply increases spring length but can't improve the power consumption effect better promptly.
