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 layer and the inner fireproof composite layer cannot fall off or be disconnected; adaptive extension is effectively carried out according to the deformation displacement degree, and the seismic insulation rubber support on the inner side is still wrapped in the whole process. Due to the improvement of the ductility, it is guaranteed that the fireproof composite layer on theouter side is not deformed, torn and damaged when the medium and violent earthquakes and large displacement offset occur, complete fireproof protection is continuously provided, and the fireproof effect under extreme conditions is achieved.
本发明公开了一种高延展性的隔震橡胶支座防火保护结构及其施工工艺，在隔震橡胶支座和柔性防火隔热材的外围还安装高延展性防火结构层，高延展性防火结构层包括：连接固定板和可延展防火隔热层，可延展防火隔热层常态下形成两层防火复合层实现防火防护，中大地震发生时产生较大的形变拉伸位移时，外层防火复合层相对于内层防火复合层形成斜向拉伸，由于二者具有重叠区域，即便拉伸位移过大，也不会造成二者的脱落或断开，有效的根据形变位移程度作出适应的延展，整个过程仍然包裹内侧隔震橡胶支座；延展性能的提升，保障了面对中大型地震、大位移偏移时，外侧的防火复合层不被形变撕裂破损，继续提供完整的防火保护，实现了极端条件下的防火效果。
