High-ductility seismic insulation rubber support fireproof protection structure and construction process thereof

The invention discloses a high-ductility seismic insulation rubber support fireproof protection structure and a construction process thereof. The periphery of a seismic insulation rubber support and the periphery of a flexible fireproof heat insulation material are further provided with a high-ductility fireproof structure layer, and the high-ductility fireproof structure layer comprises a connecting fixing plate and an extensible fireproof heat insulation layer; two fireproof composite layers are formed by the extensible fireproof heat insulation layer in the normal state to achieve fireproofprotection, when large deformation stretching displacement is generated during medium and violent earthquakes, the outer fireproof composite layer obliquely stretches relative to the inner fireproofcomposite layer, and due to the fact that the outer fireproof composite layer and the inner fireproof composite layer have an overlapping area, even if the stretching displacement is too large, the outer fireproof composite la
