Wherein, the shock insulation device comprises steel plates 4 which are distributed between the first flange plate 1 and the second flange plate 2 at intervals, and shock pads 5 are arranged between adjacent support plates 73. When the lower buttress moves, the lower buttress can drive the first flange plate 1 to shift relative to the second flange plate 2 of the upper buttress, and shearing force can occur between the steel plates 4 and the shock pads 5 which are sequentially connected together, so that the deformation offset distance of the lower buttress is increased, and the safety of the upper buttress connected with a building is improved. Meanwhile, a fireproof layer 6 is arranged between the first flange plate 1 and the second flange plate 2, and the shock insulation device is positioned in the fireproof layer 6. The fireproof layer 6 has fireproof and heat-insulating effects, can prevent the vibration isolation device from being damaged when a fire disaster occurs, and improves the practicability of the fireproof and vibration isolation support.
As shown in fig. 1, 2, 4 and 5, the first flange plate 1 is provided with resetting portions distributed around the axis of the steel plate 4, and the resetting portions are also located in the fireproof layer 6, so that the fireproof layer 6 also protects the resetting portions from fire.

When the first flange plate 1 is offset towards the left side, each second telescopic rod 16 between the first flange plate 1 and the second flange plate 2 is inclined and stretched, and each second telescopic rod 16 rotates towards the left side around the second flange plate 2, at this time, the second spring 10 correspondingly connected to the second telescopic rod 16 on the first reset portion is stretched, the second telescopic rod 16 correspondingly connected to the second spring 10 on the third reset portion is compressed, the stretched second spring 10 can pull the second telescopic rod 16 connected to the second telescopic rod back by pulling force, and the compressed second spring 10 can push the second telescopic rod 16 connected to the second telescopic rod, so that the sheared steel plate 4 and the shock pad 5 are reset.

For ease of understanding, the space above the second piston 163 in the second outer cylinder 161 is the third chamber 14, and the space below the second piston 163 is the fourth chamber 15. When the second connecting rod 162 is pulled out from the second housing, the second connecting rod 162 drives the second piston 163 to slide upwards in the second housing, the gas in the third chamber 14 is compressed, and the compressed gas acts as a buffer medium to buffer the upper pier connected to the second flange plate 2.

When the first flange plate 1 moves towards the left side, the second outer cylinder 161 on the first reset portion drives the first connecting rod 92 and the first piston 93 connected with the first outer cylinder to slide towards the first outer shell, so that gas in the first chamber 12 is compressed, the gas in the first chamber 12 acts as a buffer medium to buffer and apply thrust to the second piston 163, and the second piston 163 buffers and applies thrust to the first outer cylinder 91 connected with the second piston through the second connecting rod 162, so that the inclined first telescopic rod 9 is reset conveniently. The second telescopic rod 16 of the third resetting portion pulls the first connecting rod 92 and the first piston 93 which are connected with the second telescopic rod to compress the gas in the second chamber 13 in the first outer cylinder 91, and the compressed gas generates thrust to push the rotated second telescopic rod 16 towards the initial position, so that the recovery effect on the first telescopic rod 9 and the shock insulation device after shear deformation is enhanced.
