Bridge sling and stay cable wrapping fireproof protection system and installation method
The invention discloses a bridge sling and stay cable wrapping fireproof protection system and an installation method, and the device comprises a heat insulation layer (2) which is arranged on the surface of a bridge sling or stay cable body (1) and located on the inner layer of the protection system, and the heat insulation layer (2) is heat insulation felt or heat insulation aerogel; the heat insulation felt is made of refractory fibers including ceramic fibers or basalt fibers, and the heat insulation aerogel is formed by composite modification of high silica fibers or organic fibers; the refractory fiber cloth (4) is positioned on the outer layer of the protection system and is made of refractory fibers including ceramic fibers or basalt fibers; the preassembled plastic bag (3) is arranged between the heat insulation layer (2) and the refractory fiber cloth (4), and the preassembled plastic bag (3) is filled with vulcanized flame-retardant sealant. The fireproof materials are integrally fixed in place, on-site wet operation is avoided, on-site construction time is shortened, and the influence of installation of the fireproof materials on traffic is reduced.
本发明公开了一种桥梁吊索斜拉索外包防火保护体系及安装方法，装置包括：设于桥梁吊索或斜拉索索体(1)表面位于保护体系内层的隔热层(2)，所述隔热层(2)为隔热毡或隔热气凝胶，所述隔热毡由包括陶瓷纤维或玄武岩纤维在内的耐火纤维制成，所述隔热气凝胶由高硅氧纤维或有机纤维进行复合改性而成；位于保护体系外层的耐火纤维布(4)，所述耐火纤维布(4)由包括陶瓷纤维或玄武岩纤维在内的耐火纤维制成；以及设于所述隔热层(2)与耐火纤维布(4)之间的预装胶袋(3)，所述预装胶袋(3)内部填充硫化型阻燃密封胶。使防火材料的固定一体到位，避免了现场的湿作业，缩短了现场的施工时间，减小了防火材料安装对交通带来的影响。
